Abstract: The server of a communication system determines a communication growth level that is the level of growth of communication between one user and another user based on the cumulative count of mail send/receive events, and stores the determined growth level in the communication growth level Data Base. When the server receives a profile view request to view the profile of user A from the terminal of user B, the server determines the range of profile information to be opened for user B out of the profile of user A, based on the communication growth level of the pair of user A and user B stored in the communication growth level Data Base.

Abstract: This invention provides a network identity mark issuance/management system which can readily assure credibility of information and credibility in business in virtual worlds such as the Internet world. Upon receiving NIM issuance application information sent out by an applicant from a user terminal, an NIM issuance/management apparatus extracts user IDs registered with NIM authentication terminals from the NIM issuance application information and sends out the appropriate user ID and an authentication request to each of the NIM authentication terminals. When examination result information is received from the NIM authentication terminals in response to the authentication request and if the examination results are “accept,” the NIM issuance/management apparatus issues an NIM and sends it out to the user terminal. The user terminal receives the NIM issued by the NIM issuance/management apparatus via a network and retains it.

Abstract: It enables users to surely and easily manage the subscribed insurance in an insurance contract system which achieves a new contract, change and the like of the contract content through a portable terminal. An agency server generates a software component comprising a user profile of a user, insurance commodity information suitable for the user, a control program and a storage, and installs it to a portable terminal. The user starts the control program in the software component of the portable terminal to generate the contract content of the insurance for the new contract, contract change and the like based on information about the selected insurance commodity, inputted data of the premium and the like, the user profile, a policy number generated by the control program and the content of the storage, and then transmits it to the insurance server through a network. The insurance server, upon receiving the contract content normally, returns ACK.
