BACKGROUND OF THE INVENTION
This invention relates generally to information retrieval in a computer network. More particularly, it relates to an improved method for providing a set of bookmarks in a browser for retrieving Web pages in an Internet environment.
It is well known to couple a plurality of computer systems into a network of computer systems. In this way, the collective resources available within the network may be shared among users, thus allowing each connected user to enjoy resources
which would not be economically feasible to provide to each user individually. With the growth of the Internet, sharing of computer resources has been brought to a much wider audience. The Internet has become a cultural medium in today's society for
both information and entertainment. Government agencies employ Internet sites for a variety of informational purposes. For many companies, one or more Internet sites are an integral part of their business; these sites are frequently mentioned in the
companies' television, radio and print advertising.
The World Wide Web, or simply "the Web", is the Internet's multimedia information retrieval system. It is the most commonly used method of transferring data in the Internet environment. Other methods exist such as the File Transfer Protocol
(FTP) and Gopher, but have not achieved the popularity of the Web. Client machines accomplish transactions to Web servers using the Hypertext Transfer Protocol (HTTP), which is a known application protocol providing users access to files, e.g., text,
graphics, images, sound, video, using a standard page description language known as the Hypertext Markup Language (HTML). HTML provides basic document formatting and allows the developer to specify "links" to other servers and files. In the Internet
paradigm, a network path to a server is identified by a Uniform Resource Locator (URL) having a special syntax for defining a network connection.
Retrieval of information is generally achieved by the use of an HTML-compatible "browser", e.g., Netscape Navigator, at a client machine. When the user of the browser specifies a link via a URL, the client issues a request to a naming service to
map a hostname in the URL to a particular network IP address at which the server is located. The naming service returns a list of one or more IP addresses that can respond to the request. Using one of the IP addresses, the browser establishes a
connection to a server. If the server is available, it returns a document or other object formatted according to HTML. Web browsers have become the primary interface for access to many network and server services.
The entry of the URL in the entry field of a browser can be a difficult task for many users. While the URL for the main Web page of a major company can be relatively brief, e.g., www.ibm.com, subsidiary pages can have very lengthy URLs in, at
least to the average user, an arcane syntax. Recognizing the difficulties involved, the developers of browsers have provided one useful means of returning to a favorite URL, by the creation of user stored "bookmarks" in the browser.
Web browsers offer many options in the user interface for creating a bookmark list. Basic options let the user add and access a page through a pop-up menu on the location toolbar or through a menu pulldown from the main menu bar. A simple way
to add a bookmark for a favorite page is to enter the URL to travel to the page, once there, open the Bookmarks menu and choose the Add Bookmarks selection. This set of actions adds the URL of the current page as an item in the Bookmarks menu.
Once created, bookmarks offer a means of page retrieval. The user can cause the browser to display his bookmark list and select among his bookmarks to go directly to a favorite page. Thus, the user is not forced to enter a lengthy URL nor
retrace the original tortuous route through the Internet by which he may have arrived at the Web site. Once a bookmark is added to a bookmark list, in general, the bookmark becomes a permanent part of the browser until removed. The permanence and
accessibility of bookmarks have made them a valuable means for personalizing a user's Internet access through the browser.
Yet despite their usefulness, the current arrangement of bookmarks is not without its flaws. As the numbers of web sites and web pages on these sites have increased dramatically, so has the number of bookmarks that a typical web browser user
maintains on his browser. It is not uncommon that hundreds of bookmarks be stored in a bookmark file after a few weeks of web browsing. While folders in some browsers have helped the user group his bookmarks by category, in reality, the bookmark file
is one huge list of bookmarks, all accessible to the user through the browser. This present invention is concerned with providing structure and additional function to this amorphous entity, the bookmark file.
One problem not addressed by the current bookmark schemes is access control. In the current browser environment, all bookmarks are accessible to the user at all times. There are certain environments, e.g., a work environment or a home
environment with young children, in which this power is not an unmixed blessing.
The most common way of adding bookmarks to the bookmark file in the browser is manually intensive. Each bookmark is added one at a time. A user visits a web site, then selects that site as a bookmark entry and, if desired, categorizes it
manually. Furthermore, the current technology used in browsers to update bookmarks, i.e. removing the old address and entering the new one, is very slow and inefficient.
Bookmarks are currently used merely as an aid for navigation on a site by site basis. Once at a web site, the bookmark list is unused in navigation until a new web site in the user's bookmark list is desired. Bookmarks lend a uniform navigation
means to an otherwise unordered Web; it is unfortunate that their utility has been untapped for intrasite navigation.
These problems as well as others are addressed in various embodiments of the present invention.
SUMMARY OF THE INVENTION
Therefore, it is an object of the invention to improve the access control of a browser of the Internet.
It is another object of the invention to facilitate the management of bookmarks in the browser.
It is another object of the invention to improve the presentation and organization of bookmarks in a browser.
It is another object of the invention to flexibly configure a browser for users with different permissions.
These and other objects are accomplished by providing access to the Internet using a plurality of bookmark sets. A plurality of bookmark sets are stored in a computer system having a browser, each bookmark set including a respective set of
Uniform Resource Locators (URLs). One of the bookmark sets is designated as an active bookmark set in the browser. Browser based access to the Internet is allowed according to the URLs in the active bookmark set. When a request to retrieve an Internet
file from a designated URL is detected, e.g., by hyperlink, the designated URL is checked against the URLs in the active bookmark set. Only if there is a match between the designated URL and a respective URL in the active bookmark set is the request
allowed to proceed.
In one preferred embodiment, the creation of a bookmark set is associated with one or more passwords. The entry of the associated password is required to make the bookmark set the active bookmark set in the browser, to modify the bookmark set or
perform other actions related to the bookmark set. Since the bookmark set is a single entity an attribute can be changed for all of the bookmarks in a selected bookmark set in a single operation. Other operations such as deletion of a bookmark set can
similarly be accomplished in a single operation. In one preferred embodiment, when the list of bookmark sets is displayed, only the bookmarks of the active bookmark set are displayed.

DETAILED DESCRIPTION OF THE DRAWINGS
The invention may be run on a variety of computers or collection of computers under a number of different operating systems. The computer could be, for example, a personal computer, a mini computer, mainframe computer or a computer running in a
distributed network of other computers. Although the specific choice of computer is limited only by processor speed and disk storage requirements, computers in the IBM PC series of computers could be used in the present invention. One operating system
which an IBM personal computer may run is IBM's OS/2 Warp 4.0. In the alternative, the computer system might be in the IBM RISC System/6000 (.TM.) line of computers which run on the AIX (.TM.) operating system.
In FIG. 1, a computer 10, comprising a system unit 11, a keyboard 12, a mouse 13 and a display 14 are depicted in block diagram form. The system unit 11 includes a system bus or plurality of system buses 21 to which various components are
coupled and by which communication between the various components is accomplished. The microprocessor 22 is connected to the system bus 21 and is supported by read only memory (ROM) 23 and random access memory (RAM) 24 also connected to system bus 21.
A microprocessor in the IBM PC series of computers is one of the Intel family of microprocessors including the 386, 486 or Pentium microprocessors. However, other microprocessors including, but not limited to, Motorola's family of microprocessors such
as the 68000, 68020 or the 68030 microprocessors and various Reduced Instruction Set Computer (RISC) microprocessors such as the PowerPC chip manufactured by IBM. Other RISC chips made by Hewlett Packard, Sun, Motorola and others may be used in the
specific computer.
The ROM 23 contains among other code the Basic Input-Output system (BIOS) which controls basic hardware operations such as the interaction of the processor and the disk drives and the keyboard. The RAM 24 is the main memory into which the
operating system and application programs are loaded. The memory management chip 25 is connected to the system bus 21 and controls direct memory access operations including, passing data between the RAM 24 and hard disk drive 26 and floppy disk drive
27. The CD ROM 32 also coupled to the system bus 21 is used to store a large amount of data, e.g., a multimedia program or presentation.
Also connected to this system bus 21 are various I/O controllers: The keyboard controller 28, the mouse controller 29, the video controller 30, and the audio controller 31. As might be expected, the keyboard controller 28 provides the hardware
interface for the keyboard 12, the mouse controller 29 provides the hardware interface for mouse 13, the video controller 30 is the hardware interface for the display 14, and the audio controller 31 is the hardware interface for the speakers 15. An I/O
controller 40 such as a Token Ring Adapter enables communication over a network 46 to other similarly configured data processing systems.
One of the preferred implementations of the invention is as sets of instructions 48-52 resident in the random access memory 24 of one or more computer systems configured generally as described above. Until required by the computer system, the
set of instructions may be stored in another computer readable memory, for example, in the hard disk drive 26, or in a removable memory such as an optical disk for eventual use in the CD-ROM 32 or in a floppy disk for eventual use in the floppy disk
drive 27. Further, the set of instructions can be stored in the memory of another computer and transmitted over a local area network or a wide area network such as the Internet when desired by the user. One skilled in the art would appreciate that the
physical storage of the sets of instructions physically changes the medium upon which it is stored electrically, magnetically, or chemically so that the medium carries computer readable information. While it is convenient to describe the invention in
terms of instructions, symbols, characters, or the like, the reader should remember that all of these and similar terms should be associated with the appropriate physical elements.
Further, the invention is often described in terms that could be associated with a human operator. While the operations performed may be in response to user input, no action by a human operator is desirable in any of the operations described
herein which form part of the present invention; the operations are machine operations processing electrical signals to generate other electrical signals.
A web browser is a program that allows viewing the content of the Internet. A well known web browser is Netscape Navigator, however, many browsers exist. Some are general purpose and have many capabilities to provide a variety of functions.
Other are less capable and special purpose. In general, a web browser is a program which is capable of parsing and presenting a document written in HTML, although those skilled in the art would appreciate that other markup languages such as dynamic HTML
and XML will be used in the browsers of the future. In the present invention, the browser must also be equipped with a bookmark manager, a software module which handles sets of bookmarks which provide referents, typically URLs, to various locations in
the Internet. The bookmark manager is preferably part of the browser itself.
Upon starting a web browser, the first page the user sees is the current "home page". The URL of the home page can be regarded as the first bookmark in the browser. Although entry of a URL is one way of browsing the Web, the user may also
traverse to another Web page by clicking highlighted words, images or graphics in a page activating an associated hyperlink to bring another page of related information to the screen. Each hyperlink contains URL location information that serves as an
address of the web site. Navigational aids such as Back and Forward toolbar buttons are available to proceed back or forward to pages which have been previously accessed. Other navigation aids are the bookmarks which are used in the present invention.
In the Internet, the Web server accepts a client request and returns a response back to the client. A series of server computers may be involved in the retrieval of a specific web page. The operation of the server program is governed by a
number of server application functions (SAFs), each of which is configured to execute in a certain stop of a sequence. This sequence, illustrated in FIG. 2, begins with the authorization translation step 75 during which the web server translates any
authorization information sent by the web client into a user and a group. If necessary, the step 75 may decode a message to get the actual client request. At the name translation step 77, the URL associated with the request may or may not be translated
into a system-dependent file name, a redirection URL or a mirror site. In the path checks step 79, the server performs various tests on the resulting path to ensure that the given client may retrieve the document.
In step 81, Multipurpose Internet Mail Extension (MIME) type information, e.g., text/html, image/gif, for the given document is recognized. In the service step 83, the Web server routine selects an internal server function to send the retrieved
information back to the requesting web client. This function can run the normal server service routine to return a file or some other server function, such as a program to return to return a custom document or a CGI program. At the Add Log step 85,
information about the transaction is recorded.
A URL or "Uniform Resource Locator" is defined in RFC 1945, which is incorporated herein by reference. As is well known, the URL is typically of the format: http://somehost/somedirectory?parameters . . . " where "somehost" is the hostname
position of the URL, "somedirectory" is a directory in which the web page may be found. The usual manner in which a URL is resolved into an actual IP address for a web server is through the use of a nameserver. In an internet or intranet network, a
nameserver maps hostnames in URLs to actual network addresses. An example of a nameserver is the Domain Name Service (DNS) currently implemented in the Internet. The process of having a Web client request a hostname and address from a nameserver is
sometimes called resolution. In TCP/IP, the nameserver resolves the hostname into a list of one or more IP addresses which are returned to the Web client on an HTTP request. Each IP address identifies a server which hosts the requested content made by
the browser.
Each bookmark entry is comprised of a URL to a favorite page and an associated descriptive text string which describes the web page in such a way to be easily recognized by the user. The descriptive text can be entered by the user when creating
the bookmark set. Also, the typical browser default, when the user does not enter any descriptive text, is to use the text within an embedded "title" tag which is often sent as part of the HTML header. Other information such as pointers to cached
copies of the web page can be included in the bookmark entry.
Named Internet Bookmark Sets
Current web browsers process bookmarks as single URL entities within a single repository of bookmarks. Some browsers have the capability to organize the bookmarks by folders; however, even if a particular folder is chosen, all bookmarks remain
available for selection without restrictions. While the user can group the bookmarks into several user-specified categories, an entity which operates like the "bookmark set" described by the Applicants is lacking. The inability of prior art browsers to
process groups of bookmarks, particularly subgroups of the overall bookmark list, as an entity is disadvantageous.
For example, it is possible to include a list of bookmarks in an electronic message to another user. However, this takes a lot of manual work by one user to make the list and more work by a second user to incorporate the list into the second
user's browser's bookmark list. It is not possible to request a downloadable bookmark set which is smoothly integrated in the bookmark file of prior art browsers in a single operation.
As another example, in prior art browsers, bookmarks can not be installed as a set, nor once installed can bookmarks be managed, e.g., stored, selected or deleted, as a bookmark set. When installing bookmark entries, prior art web browsers
require the users to install each bookmark individually rather than installating a group of bookmarks as a set. Prior art web browsers do not support the concept of deleting a bookmark set, where all the bookmark entries are deleted as a set. The
maintenance of bookmark entries in the prior art web browsers requires manual intervention, handling individual URLs for all bookmark entries.
This invention creates the concept of "bookmark sets" to provide greater capability than exists in the prior art bookmark technology.
A bookmark set is an entity which has attributes of its own, e.g., active vs. inactive, and manages attributes and behavior, e.g., dynamic vs. static, of its individual bookmarks. A bookmark set is a finite collection of bookmarks that have
static and dynamic characteristics. An action such as selection, deletion or e-mail transmission can be accomplished for the entire set in a single operation by the user.
Since the bookmark list in prior art web browsers is basically one huge list, they allow unrestricted access to all bookmark entries, regardless of classification. The present invention adds the concept of an "active" bookmark set. Each
bookmark set is a collection of bookmark entries that can be made active or inactive as a working set. The active bookmark set comprises the only bookmarks which can be accessed through the bookmark mechanism.
In some embodiments below, the active bookmark set is the only list of web sites, including their subdirectories, that can be visited by use of the browser. In these embodiments, the main "user" is the program developer, the system administrator
or parent, who allows less privileged users limited access to the Internet. Those web sites outside the active set require special password permission to access. In these embodiments, a bookmark set is not only a collection of URLs, but precludes an
unprivileged user from unlimited browsing or adding more URLs to the bookmark set. This is not possible in current browsers in which the bookmark function can not be configured to limit the bookmark list to a specific URL set.
Bookmark sets allow the user to create specific sets of URLs depending on his or her needs. For example, a privileged user can configure an Office bookmark set, a Home bookmark set and a Daughter bookmark set to satisfy each of the environments
and users of the browser. Some or all of the bookmark sets may be password protected to use. In some embodiments, there is an additional password to modify or create a bookmark set. A sample "work" bookmark set is given below:
Work:
www.HTML.Reference/Definitions"//Descriptors/index.html
www.Javasoft.Javadefinition.com
w3.myproject/FVN.results.com
w3.status report.project office/myproject.status
w3.server.performance/my project.results
w3.myproject/resources1/people
The text descriptors are the "Title Page" that comes in the HTTP header.
The invention allows the association of a home page with each respective bookmark set. Thus, when the user switches the active bookmark set from his Home bookmark set to his Work bookmark set, his home page switches as well. An alternative
embodiment is to have a home page bookmark set. Each successive activation of the home page button of the browser would open a different home page window until all of the configured home pages were retrieved.
As described above, the invention allows the user to create specific and unique bookmark sets for each of the tasks for which he uses the browser. Although the bookmark set could be designated active in many ways, a bookmark set can be activated
through a browser configuration option. For example, by a "Select active bookmark set" option in a bookmark pulldown, the user can specify the unique bookmark set that is active at any one session.
For example, on a portable computer which is used both at home and work, a user can have a "work" bookmark set, a "hobbies" bookmark set, a "news" bookmark set, a "kids" bookmark set and a "financial" bookmark set using this invention. The
members of the household who use the computer can possess the appropriate passwords to the appropriate bookmark sets. They make their bookmark sets active through the use of the bookmark pulldown.
The user at work can select his "work" bookmark set as his active bookmark set. All other bookmark sets are inactive and can only be activated through the browser preferences menu. For the privileged user, the ability to manage bookmark sets as
a collection of bookmarks instead of managing one URL at a time like in the folder paradigm is advantageous. For example, the ability to change an attribute of all the bookmarks, e.g., inactive, active, dynamic, static, or to perform an action such as
deletion or password protection for all the bookmarks in the active set is part of the invention. Also, the privileged user may exercise control over the web sites to which non-priviledged users have access.
An illustrative method of creating a bookmark set according to the invention is shown in FIG. 3. Those skilled in the art will recognize that other steps in other user interfaces may be used to assemble a bookmark set. In step 101, the bookmark
manager is activated in response to user selection of the bookmark item on the browser pulldown menu. In step 103, after the menu item "Create named bookmark sets" is selected through a browser preferences menu in the browser, a creation routine for the
bookmark set is initiated. In step 105, the user is prompted for a password. Step 107 tests whether the password was entered successfully. If not entered successfully within the number of attempts allowed by the browser security protocol, the process
ends, step 109. At this point, other actions such as browser lockup, disconnect from the network as well as various alarms are possible.
Presuming the user successfully enters a password, in step 111, a new bookmark file is allocated for the new bookmark set. In the preferred embodiment, a bookmark set definition is contained within a single bookmark file. At the time of the
creation of the bookmark set, the user is prompted for a name for the set, step 113. Next, the user can specify a URL, i.e. bookmark, that belongs to the set, step 115. A text descriptor for each bookmark is also added in this step. The system tests
each bookmark and that a bookmark set name and at least one URL is added to the bookmark set, step 117. If not, the user is prompted that there is not enough information to create a bookmark list, step 119, and given an opportunity to provide the
missing information. In step 121, the user is asked whether there is another bookmark to add to the set. If so, the process returns to step 115.
The user is queried whether the bookmark set is to be password protected, in step 123. The user is prompted for the password which becomes part of the bookmark set, step 125. Step 127 represents the creation of the bookmark set and the addition
of its name into a menu of selectable bookmark sets. Once created, the users with the appropriate permissions can access the bookmark set.
The selection of the active bookmark set through the browser preferences menu is shown in FIG. 4. In step 151, the names of the selectable bookmark sets are displayed in tabular form by the browser. Those password protected may be marked by
some indicia, e.g., an icon or coloration. In step 153, in response to user selection of a bookmark set to be active, the system retrieves password information for the bookmark set, if any. If there is password protection, the user is prompted for the
password, step 155. If it is not correctly entered, step 156, after the allowed number of attempts, the process exits, step 157. Various lockup actions as described above may take place if the user attempts to access a bookmark set for which he lacks
the correct password.
If the password is correctly entered, in step 159, the selected bookmark set becomes the active set. In step 161, the browser uses entries in the active bookmark set to list the available bookmark URLs, typically as the text strings which
accompany the actual URLs. In step 163, the current page is saved as a bookmark in response to a user action in the interface, e.g., selection of "add to bookmark set" option. The save action for a bookmark for the page saves the bookmark to the active
bookmark set. In this way, the bookmark manager can automatically add bookmarks to the active bookmark set without actually requiring the user to type out the URL and text descriptor, step 165. This action of adding URLs to the bookmark set can be
protected by a separate password, if desired (not shown). In step 167, a test detects that the user has indicated that he wants to modify a bookmark in the active bookmark set. A password may be required (not shown). If allowed to change the password,
the system modifies the password in response to user input, step 168. The bookmark manager also detects whether the user wants to delete the entire bookmark set, step 169. If allowed, the bookmark manager deletes the active set in step 170 and returns
to step 151 to present the bookmark set list. The bookmark manager also detects whether the user wants to rename the bookmark set, step 171. If allowed, the active bookmark set is renamed. Only bookmarks in the active set are available for
modification, deletion or renaming in the preferred embodiment of the invention.
Other changes such as changing an attribute of the bookmark set or the type of password protection for the bookmark set are not illustrated in the figure. While any alteration of the bookmark set may be password protected by an additional level
of security, in one embodiment of the invention, a user who has access to a bookmark set automatically has the right to modify it.
The use of active and inactive bookmark sets not only provides a convenient grouping of URLs to organize the browser environment, but in one preferred embodiment, as a method to preclude the user from visiting Web sites not included in the
bookmark set. In this embodiment, only when the bookmark set is active can the user access the URLs associated with the bookmark set. (In other embodiments, the restriction only applies to access through the bookmark list pulldown menu, but not through
other means.) As shown in FIG. 5, the browser checks whether a URL is in the active bookmark list before allowing the user to browse or retrieve web pages at the site.
In step 201, the user has selected a next URL to browse, either by entry in the URL field of the browser or by activating the hyperlink in a browsed page. The reader should note that in some preferred embodiments of the browser, there is no
field in which to enter a URL so that the user is more constrained to the bookmark set. In step 203, the browser checks the selected URL against the list of URLs in the active bookmark set. If a match for the URL is not found, or in a subdirectory of a
listed URL, step 205, a panel is shown to the user indicating an error has occurred; e.g., "The requested web site can not be browsed with the current active bookmark set", step 206. A privileged user could change bookmark sets, step 207. In the
alternative, a permitted URL can be chosen, back to step 201. Persistent attempts to reach unlisted URLs could result in a browser lockup or an alarm. If the URL is listed, in step 209, the browser retrieves the web page associated with the URL and
proceeds normally.
Important implementions of the bookmark set include unique point of sale or other special purpose applications. In one implementation of the bookmark set, a user receives a CD-ROM in the mail or with a magazine. The CD-ROM contains a browser
equipped with the bookmark manager and a single active bookmark set. Thus, the browser can only access the URL addresses that the vendor wants to advertise.
Also, the kiosk or point of sale environment is another potential application for bookmark sets. In a kiosk, typically sponsored by a vendor, the browser may only have access to specific addresses. This prevents the user from accessing
unrelated URLs, wasting the vendor's resources. The retailer which owns the kiosk can rent out the kiosk to interested vendors. It is an easy matter to switch the active bookmark set with a change of vendors.
FIGS. 6A and 6B respectively show the user interface of prior art bookmark technology and the user interface of the bookmark technology of the present invention. As shown in FIG. 6A, in the prior art interface, all of the bookmarks 251 stored in
the browser are made available to the user for selection. The only possible organization of the bookmark list is by folders or topics.
FIG. 6B shows a user interface of a browser using the bookmark set technology. Notice that the user has only one active bookmark set 261 at a time. In the example, the user has three bookmark sets, Children 263, Home 261 and Office 265, and
only the Home bookmark set 261 is available using the bookmarks pulldown menu. Referring to the bookmark set manager, a user will see the current bookmarks associated with the active bookmark set. To modify or access an inactive bookmark set, if he is
allowed, the user first makes it the active bookmark set.
Internet Blacklist Bookmark Set
In this embodiment of the invention, a special type of bookmark set, the blacklist bookmark set, is introduced.
As noted above, prior art Web browsers allow unrestricted user access to any URL on the internet. A system administrator or parent that wants to restrict access to specific URLs or to a set of URLs requires an add-on program to the web browser
that filters TCP/IP addresses. This method lacks granularity, any desired URL at the same TCP/IP address is restricted as well as the undesired ones. By using the TCP/IP address as the determiner, both the acceptable and as well as the unacceptable
URLs become inaccessible to the browser.
There is no control mechanism within the prior art browser itself. As the filtering application is outside the browser, the prior art browser still makes the attempt to connect to a prohibited URL. This arrangement results in unnecessary use of
client system resources.
It would be much more useful to restrict access to unique URLs using the browser itself. While the embodiment above provides one means of controlling access to the web to the list of active bookmarks, its control is primarily a positive one.
The user has access to all of the URLs reachable from a particular Web site. This is not a fine filtering arrangement.
Thus, the invention adds the blacklist bookmark set to allow a system administrator or any browser user to specify one or more URLs, as a set of URLs for which restricted access is desired. The blacklist bookmark set contains a number of
blacklisted URLs to which a web browser user is prohibited from accessing, no matter what bookmark set is active. In effect, the blacklist bookmark set is a second active bookmark set which is always active and qualifies the access granted to the
Internet by the other active bookmark set. The use of two bookmark sets can provide a fine filtering mechanism with a minimum of URL entry.
As the reader will recall, some of the embodiments of the active bookmark set above use the active bookmark set only as a filter for bookmark access to URLs. If this is the case, the blacklist bookmark set will be the only filter. In one
embodiment of the blacklist bookmark set, it is used alone without an active permissive bookmark set of the embodiment above.
In the preferred embodiment, the blacklist bookmark set is created and modified through the browser preferences menu. The method of creating a blacklist bookmark set is similar to that described in connection with FIG. 3 above. However, at
least the removal of blacklisted bookmarks should be password protected. To add a bookmark to the blacklist bookmark set rather than the active bookmark set, the blacklist bookmark option in the browser preferences should be chosen.
The web browser user can access any URL in the current active bookmark set, except those listed in the blacklist bookmark set. In one preferred embodiment, only the system administrator can add, remove or modify blacklist bookmarks through the
browser preferences menu. However, in an alternative | | |
