Abstract
A data retrieval system is provided in which it is obligatory for a user to sign up as a member by registering with the system to register a message on a server. When registering the message, the member specifies at least one e-mail address of a person (permitted user) who is permitted to view the message registered by him/her. A seeker need not register to retrieve a message from the server. However, the seeker should have been specified as a permitted user by at least one member. In other words, as the server returns as a search result only the messages of the member who has specified the e-mail address of the seeker as the permitted user, the seeker who has not been specified as a permitted user by any of the members will be unable to view any message.
