Abstract: One objective of this invention is to provide means for selecting, from among an enormous amount of data, truly necessary information, and for distributing such selected information while maintaining the secrecy of personal information. Information, such as public user information, that a user permits to be registered is stored in the server of an information provider, which refers to such information in order to filter information that is to be distributed and to generate information choices. The information choices are then transmitted to the user terminal and the user filters them and makes second choices by referring to secret user information stored in the user terminal. The user then requests from the server the main body of information for such second choices. Upon the receipt of the user's request, the server transmits the requested main body of information and the user terminal receives and displays the information.
