A method of providing an electronic business card (EBC) access and organization service on the Web. The cardholder database is accessible and searchable from any browser connected to the Internet or the EBC service may be installed behind a conventional firewall and thus accessible only to internet users. The service thus provides easy access to cardholder contact information with privacy assured by use of integrated access restrictions. Access to and delivery of contact information by the service is not limited to a Web browser interface as commonly known today. The service provides multi-mode access and/or data delivery interfaces. The service also provides an export feature that formats search results into a pre-defined file structure readable by conventional contact management programs. Custom export file formats may also be defined to provide even wider connectivity and cross-platform utility. Access to individual records is controlled at both the record level and the field level, with multiple privacy levels for each field, in addition to the well-known "public" and "private" levels. Users having certain permissions are permitted to read a defined group of records, though not necessarily all fields in each record. A location tracking feature is also provided to allow the cardholder to rapidly designate a pre-defined contact location. Alternately, the cardholder may define a temporary contact location not normally stored in the database system. Electronic mail sent by the cardholder is automatically formatted to contain a signature hypertext link directing recipients of the email to the EBC service. This hyperlink enables the recipient of the email to rapidly access the EBC system to locate the cardholder and/or obtain additional information.

A system, apparatus and method automatically update address information of a user's outgoing and incoming messages to/from a communication network thereby relieving the user of the burden of manually entering address changes into a user address book. A plurality of users are coupled through terminals to a server in the communication network for exchanging telephone, CATV, Internet, intranet for messaging, facsimile, etc purposes. The server includes a message store; stored message profile; and is coupled to a change server linked to a network. The change server includes search rules and change options provided by the users in directing the change server in finding correct and alternative address information when erroneous or unknown information is detected in the outgoing and incoming messages. Each user address book includes a series of contacts for each user. Each contact is identified by an identification number, ID, including a name and address. The server detects message headers where a "Send To Address" is not in the address book. The change server is activated and accesses external databases for correct or alternative addresses in accordance with search rules provided by the user. The alternative or correct address books address information is installed in the users address book and the "Send To Message" process is executed. For returned messages incorporating erroneous information, the search server is again activated to access the databases for correct address information, after which the user's address book is updated thereby eliminating the time-consuming, irritating manual process of updating the user address book for outgoing and incoming messages.

A display of a card exchange device is split by a split line according to the number of card exchange persons and their seating state, and each card data is displayed in an area of a position corresponding to the seating state. Accordingly, an electronic card exchange device that is effective in business talks just after the card exchange can be provided.

Profiles in personal communication devices are updated by a method called lazy updates or demand-driven updates. In a lazy update, information is transmitted between users of personal communication devices and updates are performed only when the users communicate for other purposes. Users and service providers may update their profiles as often as they wish. Then, when a call or service request is initiated based on a given profile, the initiator of the call or service request ensures that the profile that is being used is sufficiently up-to-date for the present purpose and, if it is not, updates the profile. Lazy updates can occur when communication occurs for reasons other than solely updating the information. Examples of such updates include modification of a user's schedule or changes in the services that a service provider offers. Updates that affect future communication, such as changes in address information, telephone numbers or email addresses, happen much less frequently. However, updates such as these must occur at the time the update occurs, rather at some indefinite time in the future. Such updates are typically sent to certain designated key recipients, such as to individuals in frequent contact with the user or to selected services providers.

A method and system for setting up and managing secure data/audio/video conferences with a wide range of topologies is described. The disclosed method and system allow extending the range of topologies possible with the H.323 conferencing standards while overcoming T.120 negotiating constraints. Security in such conferences may be based on a trusted node system or on more complex security procedures. Furthermore, the taught conference topologies fully utilize the T.120 standards while also permitting the reach of the conferences to the extent enabled by the H.323 standards by implementing additional modules to manage the setting up and tearing down of one or more conference connections. In addition, the method and system allow for dynamically adjusting conference connections to improve bandwidth usage and utilize H.323 support for gatekeepers.
