DATA MONITORING PROGRAM, DATA MONITORING METHOD, AND DATA MONITORING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent information leakage.

SOLUTION: Using a surveillance program which executes encryption and decryption of data as well as surveillance of the data, a client terminal 10 generates first encrypted data from that data. Moreover, the client terminal 10 adds the surveillance program to the first encrypted data. The client terminal 10 also generates second encrypted data by executing other encryption different from the previous encryption applied to the first encrypted data to which the surveillance program is added.
