BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to electronic information distribution networks. More particularly, this invention relates to an appraisal agent which obtains electronic information from electronic information servers on behalf of an individual
end user.
2. Background
Computer technology is continuously advancing, providing newer computer systems with continuously improved performance. One result of this improved performance is an increased use of computer systems by individuals in a wide variety of business,
academic and personal applications. In some instances, these computer systems are linked together by a network or modems so that the systems can communicate with each other via electronic mail.
The current wide-ranging use of computer systems provides a relatively large potential market to providers of electronic content or information. These providers may include, for example, advertisers and other information publishers such as
newspaper and magazine publishers. Presently, however, there are no systems which allow an individual end user to automatically access specific units of this electronic information from these providers which appeal to him or her. That is, no mechanism
currently exists which allows the individual user to access only that information which has a high probability of appealing to him or her without actually browsing through all of the information himself or herself. Thus, it would be beneficial to
provide a mechanism which allows an individual to automatically access specific units of electronic information which have a high probability of appealing to him or her.
In addition, it would be beneficial to provide a system which automatically retrieves electronic information for an individual user in accordance with the user's characteristics which are observed by the system. That is, a system which
automatically retrieves units of electronic information having a high probability of appealing to the end user.
Furthermore, there are presently no systems for generating and transmitting electronic advertisements to end users operating a computer via an end-to-end electronic information distribution network. Thus, it would be beneficial to provide a
system which allows an individual end user to access specific electronic advertisements which are most appealing to him or her.
In addition, many consumers do not enjoy advertisements being forced upon them. Thus, it would be advantageous to provide a system which gives consumers some control over what types of electronic information they receive and when they receive
it.
The present invention provides for these and other advantageous results.
SUMMARY OF THE INVENTION
An electronic information appraisal agent is described herein. The appraisal agent operates within an electronic information distribution system which includes an electronic information server having multiple electronic information units.
Requests for electronic information are transferred from the appraisal agent to an electronic information server, which compares the contents of the server to a set of search criteria. In one embodiment, the server returns a set of electronic
information to the appraisal agent which matches the search criteria. In another embodiment, the server returns information indicating whether the search criteria matched any information in the server.
In one embodiment, the electronic information distribution system also includes a metering server which is coupled to the electronic information server and the client system. The metering server allows multiple client systems to receive
electronic information units from the electronic information server.

DETAILED DESCRIPTION
In the following detailed description numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be
practiced without these specific details. In other instances well known methods, procedures, components, and circuits have not been described in detail so as not to obscure the present invention.
FIG. 1 shows a network system 10 of one embodiment of the present invention. The network 10 includes a plurality of client systems 12 coupled to a metering server 14 within a local area network (LAN) 16. Alternatively, a single client system 12
may be coupled to a metering server 14. Each client system 12 may be a personal computer that is operated by an end user. Alternatively, each client system 12 may be any other type of consumer consumption device, such as a television set, a game
machine, etc. The server 14 is typically a dedicated computer that provides an interconnect contact node which allows the client systems 12 to communicate with the server 14 and other client systems 12. The server 14 may contain resident modem sharing
software that allows the server 14 and client systems 12 to communicate with a device external to the local network 16. The server 14 is also capable of maintaining resident databases. Both the server 14 and the client systems 12 contain the necessary
interface hardware and software required to transfer information between the components of the system 10.
The metering server 14 is coupled to a publisher unit 18 through a plurality of clearinghouse servers 20. By way of example, the publisher 18 may be connected to the server 14 as part of an overall wide area network (WAN) that allows the server
14 and publisher unit 18 to transfer information. The system 10 may also have a yellow page server 22 coupled to the publisher unit 18 and the metering servers 14. The publisher unit and servers of the WAN system contain the interface hardware and
software necessary to transfer electronic information between the components of the system. As shown in FIG. 1, the system 10 may have multiple client systems 12 coupled to a single metering server 14 and multiple servers 14 coupled to a single
clearinghouse server 20, a regional content database server 21 and a single yellow page server 22. There may be multiple clearinghouse and yellow page servers located at regional centers throughout the country/world. In addition, depending on the size
of a community, there may also be multiple yellow page servers for each local community. Although the publisher 18 is referred to as a publishing unit, it is to be understood that the publisher unit 18 can also be a node for an advertiser 18 and that
the use of the terms publisher and advertiser may be synonymous. Each client system 12 is provided with an interface, such as a graphic user interface (GUI), that allows the end user to participate in the system 10.
The GUI contains fields that receive or correspond to inputs entered by the end user. The fields may include the user's name and possibly a password. The GUI may also have hidden fields relating to "consumer variables." Consumer variables refer
to demographic, psychographic and other profile information. Demographic information refers to the vital statistics of individuals, such as age, sex, income and marital status. Psychographic information refers to the lifestyle and behavioral
characteristics of individuals, such as likes and dislikes, color preferences and personality traits that show consumer behavioral characteristics. Thus, the consumer variables refer to information such as marital status, color preferences, favorite
sizes and shapes, preferred learning modes, employer, job title, mailing address, phone number, personal and business areas of interest, the willingness to participate in a survey, along with various lifestyle information. This information will be
referred to as user profile data. The end user initially enters the requested data and the non-identifying information is transferred to the metering server 14. That is, the information associated with the end user is compiled and transferred to the
metering server 14 without any indication of the identity of the user (for example, the name and phone number are not included in the compilation). The GUI also allows the user to receive inquiries, request information and consume information by
viewing, storing, printing, etc. The client system may also be provided with tools to create content, advertisements, etc. in the same manner as a publisher/advertiser.
All of the fields in the GUI relating to consumer variables are hidden from the consumer. The display of the GUI is based upon these fields, but the GUI does not display them to the user except when the user brings up a "profile editor", as
discussed in more detail below. Thus, the monitoring of consumer actions and inactions based on these consumer variables and the updating of user profile data is transparent to the consumer. In addition, modifications made to the electronic information
to customize it to a particular consumer are also transparent to the consumer.
The publisher/advertiser 18 is provided with software tools to create electronic information which includes content and advertisements that can be transmitted over the system. The electronic information may allow an end user to access a content
database, or the information may be all or a portion of a content database. By way of example, the content database may be the text and video of an electronic newspaper. The content database may reside within the publisher unit or be located at a
remote location such as the metering server or a regional server that services a plurality of metering servers. The software tools may include a hypertext oriented mark up language that routes distributed end users to the content databases.
In one embodiment, the software tools provided to the publisher/advertiser 18 include software tools for embedding consumer variables within electronic information. The embedded consumer variables enable a client activity monitor and a
consumption device to monitor consumer interaction with the electronic information based on the consumer's interaction with the unit of information currently being consumed. This interaction includes both inputs by the consumer and actions which the
consumer could have taken but chose not to. In one implementation, the publisher/advertiser 18 is provided with a GUI which allows the publisher/advertiser 18 to select certain consumer variables from a set of consumer variables and associate the
selected variables with specific objects or fields within the electronic information. For example, the electronic information may include several option fields from which end users may select. The publisher/advertiser 18 may associate a color
preference variable with these option fields, thereby indicating to the client systems 12 to track the color of the option field selected by the end user.
The publisher/advertiser 18 is also provided with software tools to create electronic information in a wide variety of consumption formats that can be transmitted over the system. These consumption formats include formats such as audio, video,
graphics, animation, text, etc. For example, an advertiser 18 may create an advertisement for a camera which describes the camera in both audio and video format. Both of these consumption formats are transferred to the metering servers 14, and
subsequently to the client systems 12. The end user is then able to consume the advertisement in whichever format he or she prefers, or alternatively in both formats.
In one embodiment, each piece of electronic information received by client system 12 includes a header block which includes the consumer variables and their related objects or fields for that piece of electronic information. For example, the
header block of a given piece of electronic information may include an indicator that a color preference variable is associated with certain option fields. In addition, default colors for particular fields or objects, or a default consumption format,
such as audio or video, for the electronic information may also be included in the header block.
As shown in FIG. 2, each client system 12 includes a session manager 29, a client interface 23, a client activity monitor 24, a content adapter 25, a statistic compilation process 26, and a personal profile database 27. The client interface 23
provides individual users with access to the system 10. Interface 23 may be any of a wide variety of user interaction devices. For example, the client interface 23 may be the display device and input device of a personal computer based on an
Intel(.RTM. microprocessor architecture. Alternatively, the client interface 23 may be a display and input device coupled to, or part of, any of a wide variety of consumer consumption devices, such as a television set or a game machine. In one
embodiment, the client interface 23 is a physical device which is separate from the remainder of client system 12. For example, client interface 23 may be a personal computer system, while the remaining components of client system 12 are contained in a
separate box or similar physical device coupled to the personal computer system. Interface 23 supports any one or more of a wide variety of conventional input methods, including alphanumeric keyboard inputs, voice inputs, cursor control inputs (such as
a mouse or trackball), touchscreen inputs, etc.
Session manager 29 transfers data and control information to and from the components of client system 12, and acts as an interface between client system 12 and metering server 14. Electronic information which is transferred to client system 12
is received by session manager 29 and forwarded to client interface 23. In one embodiment, the electronic information is forwarded to client interface 23 via content adapter 25. Content adapter 25 may then modify the electronic information, based on
the end user's data stored in personal profile database 27. Session manager 29 also instructs statistic compilation process 26 to compile the aggregate data stored in personal profile database 27 when the information is requested by metering server 14.
The client activity monitor 24 tracks the consumer variables corresponding to the preferences of the end user(s) of client system 12. When an end user consumes electronic information, and also possibly interacts with that electronic information,
client activity monitor 24 associates the electronic information with the appropriate consumer variables and stores this data in the personal profile database 27. For example, the client activity monitor 24 tracks the color of fields or objects that are
selected most frequently and least frequently by the end user. Similarly, the consumption format chosen most frequently and least frequently by the end user, such as audio or video, is also tracked and stored in personal profile database 27. In one
embodiment, the consumer variables and corresponding fields or objects are indicated in a header block received with the electronic information.
The personal profile database 27 maintains the user profile data for the end user(s) of client system 12. For example, age, gender, income, marital status, color preferences, etc. are stored in personal profile database 27 for each individual
end user of client system 12. In addition, personal profile database 27 may also include additional information such as credit card numbers, social security numbers, mailing addresses, preferred shipping methods, etc. for each individual end user to
facilitate ordering items displayed in advertisements.
Personal profile database 27 is updated with user profile information based on the activity monitored by client activity monitor 24. In one embodiment, this information can also be directly modified by the end user. For example, client
interface 23 may include the ability to access the user profile data for a particular end user which is stored in personal profile database 27, such as through a GUI profile editor. The end user is then able to alter this data, which is then returned to
metering server 14 (via statistic compilation process 26 discussed below), and used by content adapter 25 discussed below.
In one embodiment, the information in personal profile database 27 is protected from access by anyone other than the individual who is associated with the information. For example, the information may be protected on a computer by encrypting the
profile when it is not in use. Alternatively, the information may be stored on a removable nonvolatile storage device, such as a PCMCIA Flash memory card. Thus, an individual may remove the Flash-based profile card from a computer and thereby remove
the risk of exposure of private information to other individuals operating in the network system 10. In addition, since the profile is removable, individual end users can move a profile from computer to computer, such as between office and home.
All of the information stored on the removable storage device is also encrypted. To access the consumer profile, the consumer inserts the card into the client system 12, which prompts the consumer for a personal identification number (PIN) or
password. Upon receiving the correct PIN, the client system 12 decrypts the profile information in the storage device and stores the decrypted profile information in the client system's volatile memory. The consumer is then able to utilize the profile
(transparently). The profile in volatile memory is re-encrypted periodically and stored back to the storage device. When the consumer finishes using the client system 12, the final profile revision is encrypted and stored in the storage device. The
card is then ejected from the client system 12 and pocketed by the consumer, and the un-encrypted profile information in the volatile memory is deleted.
The content adapter 25 customizes electronic content to the individual end user based on the user profile data contained in personal profile database 27. Electronic content received by system 12 from metering server 14 may include fields which
can be customized. Which fields can be customized may be indicated in a header block received with the electronic content. For example, a unit of electronic information may be received with a particular field having the default color of green. If
personal profile database 27 contains sufficient data regarding color preferences for the individual end user, then content adapter 25 changes the color of that particular field from green to whatever color preference is contained in personal profile
database 27 for that individual end user. Similarly, the default consumption format may be video, but if personal profile database 27 indicates that the end user prefers audio format, then content adapter 25 delivers the audio format version of the
electronic information to the client interface 23 rather than the video version.
Data is collected for personal profile database 27 by direct input from the end user and also by client activity monitor 24 monitoring the end user's activity. When the end user consumes a piece of electronic information, each variable (or a
portion of each variable) within the header block for that piece of electronic information is added to the database for this end user. For example, if this piece of electronic information is made available to the end user for consumption in both audio
and video format, and the end user selects the audio format, then this selection is stored in personal profile database 27 for this end user.
When sufficient data has been collected for a particular consumer variable, then content adapter 25 uses that consumer variable to customize received electronic content to the end user. The amount of data which is sufficient is dependent on the
particular consumer variable. For example, once personal profile database 27 has collected ten consumption format selections from this end user and all ten have been for video format, content adapter 25 may determine that this is sufficient data to
customize incoming electronic information. However, content adapter 25 may determine that sufficient data has not been collected to customize colors if this end user has selected ten different fields, six of which were purple and four of which were
green.
In one embodiment of the present invention, the end user is able to override any compiled user profile data. For example, even though the end user may select a field with the color purple most frequently, the end user is able to modify the user
profile data to indicate that green is the preferred color. In one implementation, the statistic compilation process 26 uses this input by the end user for its data compilation. Alternatively, the statistic compilation process 26 may use the data
collected by client activity monitor 24 for its data compilation, or the statistic compilation process 26 may utilize both the end user and the data collected by client activity monitor 24.
Statistic compilation process 26 compiles the user profile data contained in personal profile database 27 and transfers the compiled data to metering server 14. Statistic compilation process 26 aggregates the user profile data in personal
profile database 27. That is, statistic compilation process 26 compiles all of the user profile data in personal profile database 27 except for information which identifies a particular individual. For example, information such as the end user's name,
social security number, address and credit card numbers are not included in the compilation. Thus, client system 12 transfers the compiled data to metering server 14 without divulging any confidential information to the advertisers/publishers.
It should be noted that, under certain circumstances, identifying information such as a name and credit card number may be provided to the publisher/advertiser. For example, an advertisement for a camera received by the end user may have a "buy"
option associated with it. If the end user selects the buy option, then session manager 29, transfers the end user's name, credit card number, and address to the advertiser. Given this information, the advertiser is able to charge the purchase price of
the camera to the end user's credit card and ship the camera to the end user.
In one embodiment, client interface 23 provides the end user with access to personal profile database 27 which allows the end user to select certain criteria to be omitted from the compilation process. For example, an end user may select to omit
details such as color preferences, income, marital status, age, gender, etc. Alternatively, for demographic information, the user may not initially provide certain information to the personal profile database 27, thereby preventing its inclusion in the
compilation.
In one embodiment of the present invention, statistic compilation process 26 compiles electronic content-specific information for return to the metering server 14. This information includes, for example, how much time the end user spent
consuming the electronic content, and how much of the content was consumed. For example, a particular advertisement may include ten different screens which are displayed to the end user. If the end user spends 15 seconds viewing the first screen and 15
seconds viewing the second screen and then terminates the advertisement, the statistic compilation process 26 transfers information to the metering server 14 indicating that an individual with this end user's user profile data spent 30 seconds viewing
the electronic information and that the content was 20 percent consumed (that is, two screens out of ten were consumed). Additionally, information indicating the specific elements of the advertisements that were consumed (for example, the first two
screens) is also transferred to the advertiser. Note that, as discussed above, this aggregate information does not reveal the identity of the end user who consumed the advertisement.
In one embodiment of the present invention, the client system 12 also includes an appraisal agent(s) 28. The appraisal agent 28 provides the end user with an agent which can search various yellow page servers 22 to locate electronic content
which matches the end user's user profile data. For example, the end user may desire to view five different electronic advertisements per day. The appraisal agent 28 accesses the user profile data for the end user from the personal profile database 27
to determine the search criteria for this end user, and then sends a request(s) to yellow page servers 22 or content servers 21 to locate electronic information which matches the search criteria. In one implementation, the number of electronic
advertisements a user desires to view per day is included in personal profile database 27. In one embodiment, multiple appraisal agents 28 may be initiated by a single end user, with each appraisal agent 28 performing a different search.
In one embodiment, the appraisal agent 28 sends requests to a yellow page server 22 rather than a content server 21, unless programmed to do otherwise. For example, when the end user instructs the appraisal agent 28 to search for electronic
content, the appraisal agent 28 sends requests to yellow page servers 22. However, if an end user desires articles in a particular area of interest, the user can program the appraisal agent 28 to send requests to a content server 21 rather than a yellow
page server 22.
Alternatively, the appraisal agent 28 may be programmed by the end user to locate a particular item. For example, the end user may program the appraisal agent 28 to locate, and possibly purchase, a camera. The end user would define the search
criteria for the appraisal agent 28 to find an advertisement(s) for a camera which meets the end user's needs, such as a particular brand, features, price, etc. Once located, the advertisement is returned to the end user. Alternatively, the appraisal
agent 28 may be programmed to purchase an advertised camera once an advertisement is found which matches the search criteria. The appraisal agent 28 may be programmed to locate advertisements in a wide variety of manners. For example, the end user may
input all or part of the search criteria, such as a particular item and manufacturer, directly to the appraisal agent 28 via a GUI. Alternatively, the appraisal agent 28 may obtain the search criteria by accessing the personal profile database 27 of the
client system 12. For example, the appraisal agent 28 may access the personal profile database 27 to determine the end user's income, age, marital status and personal interests. Which characteristics are used as the search criteria may be
pre-programmed in the appraisal agent 28 (for example, income and age), or may be indicated by the end user.
The appraisal agent 28 searches for information by making a request(s) to the yellow page servers 22. This request includes the search criteria and is transferred to the metering server 14. The session manager 38 of the metering server 14
receives and forwards the request to a yellow page server 22. The request is received by the session manager 78 of the yellow page server 22, shown in more detail in FIG. 5. Then, via the interactive process 76, session manager 78 accesses the
advertising database 70 to determine whether electronic information in the advertising database 70 matches the search criteria of the request.
The session manger 78 determines whether a match exists by comparing the search criteria to consumer variables, key words, advertisement text, etc. stored with each advertisement in the advertising database 70. This data may be stored, for
example, in header information along with each advertisement. Whether the session manager 78 determines a match exists is dependent on the request issued by appraisal agent 28. For example, if the appraisal agent 28 is programmed to purchase an item,
such as a camera, having certain features (that is, the search criteria), then an exact match may be required. That is, several search criteria may be listed, such as price, manufacturer, color, etc., and a match occurs only if each one of the several
search criteria are satisfied by a particular advertisement. By way of another example, the appraisal agent 28 may be searching for electronic advertisements which match a set of several search criteria in order to return the advertisements to the end
user. Under these circumstances only a portion of the search criteria, such as four out of seven criteria, may need to be satisfied, as indicated by the user. That is, if an advertisement is found which closely matches the search criteria, then the
advertisement is returned to the end user, even if it isn't an exact match.
If the session manager 78 determines electronic information exists in the advertising database 70 which matches the search criteria, then the matching information is returned to the appraisal agent 28 via the metering server 14. Similarly, if
the appraisal agent is programmed to purchase an item, such as a camera, and a match is found, then the appraisal agent 28 may place an order for the item and return a receipt to the end user, indicating that the item has been purchased.
In one embodiment of the present invention, all financial transactions for such purchases are encrypted in order to maintain consumer privacy. The transactions can be encrypted using any of a wide variety of commercially available encryption
algorithms. In addition, all financial transactions are also digitally signed for authentication purposes. If a requested transaction does not include this digital signature, then the request is denied. This digital signature is input by a consumer,
for example, utilizing a mouse or other cursor control device, or utilizing a pen and touch-sensitive input pad.
If, however, the session manager 78 determines that no electronic information exists in the advertising database 70 which matches the search criteria, then a response is returned to the appraisal agent indicating no match was found. In one
embodiment, this response is indicated to the end user. Alternatively, the appraisal agent 28 may repeat this process by accessing another yellow page server 22. For example, the appraisal agent 28 may first access a local yellow page server 22 in an
attempt to match the search criteria. If the search fails at the local level, the appraisal agent 28 may then access a regional yellow page server 22, and if that search is unacceptable, access a national yellow page server 22, etc.
In an alternate embodiment, the session manager 78 within a yellow page server 22 transfers a request from an appraisal agent 28 to multiple other yellow page servers 22 once the request is received. Thus, multiple yellow page servers 22 attempt
to satisfy the search criteria concurrently, rather than requiring the appraisal agent 28 to send a request to each yellow page server 22 independently. If a yellow page server 22 contains an advertisement which satisfies the request, then the session
manager 78 of that yellow page server 22 returns the matching information to the appraisal agent 28 and notifies the session manager 78 of the yellow page server 22 which received the request from the appraisal agent 28 that a match has been found.
Alternatively, the yellow page server 22 which contains a match may return the matching information to the yellow page server 22 which received the request from the appraisal agent 28, which then returns the matching information to the appraisal agent
28.
When requesting electronic advertisements, the data returned to the end user is dependent on the end user's request. For example, the end user may define certain results which should occur based on how well the electronic information matches the
search criteria. The appraisal agent 28 may be programmed to return the title of the electronic advertisement if it is only a 5% match to the search criteria, an abstract if it is a 25% match to the search criteria, and the entire advertisement if it is
a 95% match to the search criteria. Alternatively, the appraisal agent 28 may be programmed to return only titles, regardless of how well the advertisements match.
In addition, an individual end user may desire to consume only a certain number of electronic advertisements. For example, a user may desire to view only five advertisements per day. This information can be made available to the appraisal agent
28, such as by directly inputting the information to the appraisal agent 28 or storing the information in the personal profile database 27 which is accessed by the appraisal agent 28. Thus, in one embodiment the appraisal agent 28 retrieves the
specified number of electronic advertisements which match the search criteria of the end user each day. Alternatively, the appraisal agent may then display titles of 25 electronic advertisements which match the search criteria for the end user to
review, and allow the end user to select which advertisements he or she will consume.
Thus, by retrieving electronic information which matches the search criteria (which reflects the user profile characteristics of the individual end user), the appraisal agent 28 provides electronic information which has a high probability of
appealing to the end user.
In addition to receiving electronic information in the form of advertisements, the end user of client system 12 may also receive other electronic information, such as electronic content placed in clearinghouse servers 20 by publisher 18 or
electronic content in content database 34 of metering server 14. For example, this electronic content may be a newspaper or magazine article, or an encyclopedia entry. In one embodiment, this electronic content contains the same consumer variables in
header blocks as the electronic advertisements, and is customized by client system 12 in the same manner as discussed above.
As shown in FIG. 3, resident within each metering server 14 is a user profile database 30, a transaction database 32, a content database 34 and an index database 35. The user profile database 30 contains aggregate profile data for the
consumption devices served by the metering server 14 which is collected from the client systems 12, along with subscriber information. In one embodiment, the metering server 14 periodically requests the user profile data stored in the client systems 12.
The transaction database 32 contains the end user's account along with a log of the transaction, including the price of the transaction. The transaction database 32 may also contain the balance and a credit limit for each end user account The
content database 34 contains units of electronic information. The index database 35 contains titles for each electronic information unit. In one embodiment, the metering servers 14 also have access to a regional content database server(s) 21 which
contains a larger content database.
Thus, the metering server 14 contains an account balance, a user identification (such as an account number or a name), and may also include information indicating which information the user subscribes to. User profile data requested by metering
server 14 from the client systems 12 is stored in user profile database 30, along with user profile data corresponding to electronic information being consumed by an end user. As discussed above, this user profile data does not specifically identify the
individual end user. The account balance and user identification is contained in the transaction database 32. Therefore, the only information which is contained in the metering server which identifies an individual end user is that user's
identification and an account balance, thereby maintaining the user's privacy.
In one embodiment, the transaction database 32 also includes, in the log of a transaction, an indicator of the electronic information consumed. By maintaining such a log; the metering server 14 is able to summarize an end user's consumption for
that user's review. For example, the metering server 14 may generate a monthly statement summarizing how much money the end user spent consuming electronic information.
Each metering server 14 also contains a metering process 36, a billing process 37 and a session manager 38. The metering and billing processes 36 and 37 access and process information in response to instructions from the session manager 38. For
example, when an end user requests a unit of information, the request is received by the session manager 38. The session manager 38 instructs the metering process 36 to retrieve the requested unit of information. In one embodiment, the metering process
36 then initially accesses the user profile database 30 to determine whether the end user is a subscriber of the information. If the end user is a subscriber, the metering process 36 retrieves the unit of requested information from the content database
34, wherein the information can be transmitted to the end user.
If the end user is not a subscriber, the metering process 36 calculates the price of the requested information and accesses the transaction database to subtract the price from the balance of the end user's account. The balance is initially
established when the end user requests an account in the system. The balance may be specified by the end user and approved by the clearinghouse server. Approval may be based upon a credit card number or bank account number provided by the end user.
The balance may be updated by the clearinghouse server when the end user pays his bill. If the balance minus price is greater than zero, the metering process 36 retrieves the information and sends the same to the end user. If the balance minus price is
less than zero, the metering process 36 does not retrieve the information and may send a message to the end user that the balance has been exceeded. The initial balance of the account is typically set by a credit limit.
In one embodiment, requests for information are made by the appraisal agent 28. In this embodiment, the metering process 36 checks whether the content database 34 contains information matching the search criteria provided by appraisal agent 28.
If a match exists, then electronic information is returned to the client system 12, provided the end user which initiated appraisal agent 28 is a subscriber of the information, or has a sufficient balance in his or her account to pay for the electronic
information.
By way of another example, a clearinghouse server 20 may request billing information from the metering server 14 about the end users, or a specific end user. The session manager 38 receives the request and instructs the billing process 37 to
retrieve the information. The billing process 37 then retrieves the billing information from the transaction database 32 and transfers the information to the clearinghouse server 20. The clearinghouse server 20 may also request user profile data,
wherein the billing process 37 retrieves the profile data from the user profile database 30. Additionally, the information may be targeted to end users with specific profiles. Upon receiving and storing the targeted information in the content database
34, the metering process 36 accesses the user profile database 30 to find end users with matching profiles. The metering process 36 then sends the content titles to the end users with matching profiles.
In one embodiment, the software tools also provide an interactivity builder to allow the end user to interact with the electronic information. For example, the electronic information may be a content database that is analogous to the "yellow
pages" of a phone book. The yellow page content database may contain a plurality of advertisements that can be viewed by the end user. The software tools may allow the publisher to build an object that allows the end user to search the contents of the
content database. The software tools may also allow the publisher/advertiser to combine different types of information. For example, the publisher can combine video, audio, graphics, animation and text all within the same unit of electronic information
provided to the end user.
The software tools include "cost type" and "cost value" fields that accompany each unit of electronic information. The cost type and cost value can be utilized to calculate a price that can be either credited to or debited from the end users.
The fields allow the publisher/advertiser 18 to establish the manner in which the information will be charged to the end user's account. One example of a cost type is "pay per view" payment method, wherein the end user pays an associated cost each time
the user consumes a unit of information. This cost may also be proportional to the amount consumed, so that the cost is higher for consuming the entire unit information rather than a smaller portion, such as the abstract. This type of payment may be
desirable for information which is typically seldom consumed by the end user. Other cost types include payment on a per byte or word of information viewed by the end user, or payment for the period of time that the user consumes the information. These
cost types may be desirable when the end user is accessing a database that contains, for example, corporate or individual credit information, or the drawings and text of a patent database.
The user may also subscribe to units of information, either individually, or through a group such as the employer of the end user. For example, the end user may wish to subscribe to a news database that provides the end user news information
upon command for a monthly, yearly, etc. charge. The cost types may also include a one-time charge for a unit of information, wherein the end user is granted access-to the unit of information for the life of the unit.
The cost types may be provided as part of a menu that can be selected by the publisher. For example, the menu may appear to the publisher as follows:
"Pay Per View"
"Pay Per Byte"
"Pay Per Time"
. . "
The cost value is provided in a different field and may be embodied by a simple data entry by the publisher. For example, if the pay per view cost type is selected, the publisher may enter "$1.00". If the pay per byte cost type is selected, the
publisher may enter "$0.10 per Mbyte", and so forth and so on. The tools may also allow the publisher to associate a plurality of cost types and corresponding cost values with the same content of information.
In addition to debit models, the software tools may also allow the publisher/advertiser 18 to build a credit model which credits the end user's account each time the user views a unit of information. This model is particularly useful for
advertisers who may want to credit the end user's account to encourage the user to consume an advertisement. By way of example, the credit model can be used in association with the yellow pages content database. The publisher/advertiser may also be
provided with a field that allows the publisher/advertiser to select between credit and debit.
In one embodiment, the software tools allow the publisher/advertiser 18 to request certain profile data associated with the consumption of a unit of information. For example, associated with a unit of information may be a request to provide the
publisher/advertiser with certain user profile data such as the age or income of the viewers who viewed the information. Additionally, the tools may also allow the publisher to request that the unit of information be directed only to end users that have
a certain profile. For example, the publisher/advertiser may request that a unit of information be directed only to male end users or end users that have historically viewed news items. The target user profile may be associated with a pricing hierarchy
for advertising information, such that a targeted end user receives a larger price credit than an end user that was not targeted by the advertiser.
