INFORMATION PROCESSOR, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent information leakage by controlling access to files stored in a client terminal without degrading accessibility.

SOLUTION: An information processor can communicate with a server which determines whether to transmit a key for decrypting files stored in the information processor according to topology of the information processor to a network. The information processor detects the topology to the network, transmits a key acquisition request including the detected topology to the server, and acquires a decryption key transmitted from the server, then decrypts the files stored in the information processor by using the decryption key.
