CONSTITUTION: A user DB(121) stores user information such as a name, an address, an age, a school, a password etc. A meeting DB(122) records meeting information such as a meeting name, participators, a password, an operator etc. A cryptogram manufacturing program(123) creates a meeting code key and a group identification key by managing a coded secret sharing directory. A certification program(124) is linked with the user DB(121) by a predetermined period and certifies a validity of an identity information file. An identity information file manufacturing program(125) creates an identity information file by linking with the user DB(121), the meeting DB(122). and the cryptogram manufacturing program(123). A control unit(126) contacts to a P2P program being mounted in a user's terminal and controls each programs and records information inputted/outputted to each DB.
