Abstract
PURPOSE:To prevent personal information from leaking to the outside, by enciphering resident fundamental register data stored in a resident fundamental register file, by using a cipher key which has been determined in advance. CONSTITUTION:A cipher processing part 3 is constituted of an enciphering part 31, a key managing part 32, and a decoding part 33, and at the time of inputting the resident fundamental register data, the resident fundamental register data is enciphered by an enciphering means by using a cipher key which has been determined in advance and stored in a resident fundamental register file 4. In such a way, even if the resident fundamental register file 4 is carried out and it is tried to read out the resident fundamental register data by using a means such as file dumping, etc., the resident fundamental register cannot be decoded since it is enciphered, therefore, it can be prevented that personal information on the resident fundamental register data stored in the resident fundamental register file 4 leaks out to the outside.
