Validity checking system, validity checking method, information processing card, checking device, and authentication apparatus

A validity checking system comprising:

• an information processing card that has an information processing function;
• and
• an authentication system that performs mutual authentication with the information processing card,
• wherein
• the information processing card includes:
• a validity authenticating unit that authenticates validity of the authentication system;
• and
• an impersonation preventing unit that performs an impersonation preventing process on a result of the authentication performed by the validity authenticating unit, and
• the validity checking system further comprises:
• a verification device that includes a verifying unit that receives the authentication result that is subjected to the impersonation preventing process and is output from the information processing card, and verifies the authentication result;
• and
• a checking device remotely connected with the authentication system, which checking device includes a verification result output unit that outputs a result of the verification received from the verification device to a user in a perceptible manner.

A validity checking method that is used in a validity checking system that includes an information processing card, an authentication system that performs mutual authentication with the information processing card, and a checking device that receives information output from the information processing card,

• the validity checking method comprising:
• a validity authenticating step of authenticating validity of the authentication system, the validity authenticating step being carried out by the information processing card;
• an impersonation preventing step of carrying out an impersonation preventing process on a result of the authentication performed in the validity authenticating step, the impersonation preventing step being carried out by the information processing card;
• an authentication result outputting step of outputting the authentication result subjected to the impersonation preventing process to outside, the authentication result outputting step being carried out by the information processing card;
• a verifying step of receiving the authentication result that is subjected to the impersonation preventing process and is output from the information processing card, and verifying the authentication result, the verifying step being carried out by the checking device that is remotely connected with the authentication system;
• and
• a verification result outputting step of outputting a result of the verification performed in the verifying step to a user in a perceptible manner, the verification result outputting step being carried out by the checking device.
