Information exchange/share system, method and program thereof

An information exchange/share system which exchanges, via a communication means, information between a terminal of an information provider which provides the information to be distributed and a terminal of an information requester which requests an access to the distributed information, the system comprising:

• a message sharing/storing unit which stores the information provided from the terminal of the information provider, and accessibility information for setting an information requester which is allowed to access the information;
• an access control function which determines whether or not information requested in an information request message is present in the message sharing/storing unit, and determines, based on the accessibility information, whether or not an information requester which requests the information requested in the information request message from the information requester is allowed to access the information;
• and
• a provision requesting function which creates information-provision request information to the information provider when it is determined that the information requested in the information request message from the terminal of the information requester is already stored in the message sharing/storing unit and that the information requester is not allowed to access the information based on the accessibility information or the information requested in the information request message is not stored in the message sharing/storing unit.

A method for an information exchange/share system which exchanges, via a communication means, information between a terminal of an information provider which provides the information to be distributed and a terminal of an information requester which requests an access to the distributed information, and which includes a message sharing/storing unit which stores the information provided from the terminal of the information provider, and accessibility information for setting an information requester which is allowed to access the information, the method comprising:

• an access control step of checking whether or not information requested in an information request message from the terminal of the information requester is present in the message sharing/storing unit, and of determining, based on the accessibility information, whether or not an information requester which requests the information requested in the information request message is allowed to access to the information;
• and
• an automatic reply step of creating request-reply-message information to the information requester based on the information in the message sharing/storing unit without transmitting the information request message to the terminal of the information provider when it is determined that the information requested in the information request message from the information requester is already stored in the message sharing/storing unit and that the information requester is allowed to access the information.
