PROBLEM TO BE SOLVED: To surely secure the secrecy protection of secret information managed on an information processor without forcing work burden. SOLUTION: Through a radio communication part 35, a CPU 30 performs short-distance radio communication with an object (certificate device for storing the information of access right) put on the body of a person having the right capable of accessing the secret information not to be known by the other person during the work of that information and performs certifying processing while using security related data 36 so as to detect whether the person having the access right is located close or not. When it is detected the person having the access right gets away, the secret information during that work is automatically enciphered and the secret information during work before enciphering is automatically erased so that the other person can not know the secret information. |
