Information processing apparatus, information processing method and storage medium

A non-transitory computer readable medium for storing an information processing program causing a computer to execute a process comprising:

• authenticating a user in a condition where an authentication medium used for authenticating the user is inserted, the authentication medium storing personal identification information of the user, a private key, and a software program for using the private key and including a processor for running the software program, to thereby establish a verified state in which the user is allowed to use the computer;
• performing data processing including processing related to the private key stored in the authentication medium;
• detecting completion of the private key related processing;
• and
• based on detection of the completion of the private key related processing, changing the verified state of the user having been established as a result of authenticating the user to a user unverified state.

An information processing method comprising:

• authenticating a user in a condition where an authentication medium used for authenticating the user is inserted, the authentication medium storing personal identification information of the user, a private key, and a software program for using the private key and including a processor, implemented at least partially in hardware, for running the software program, to thereby establish a verified state in which the user is allowed to use the computer;
• performing data processing including private key processing in which the private key stored in the authentication medium is used;
• detecting completion of the private key processing;
• and based on detection of the completion of the private key processing, changing the verified state of the user having been established as a result of authenticating the user to a user unverified state.

An information processing apparatus configured to:

• authenticate a user in a condition when an authentication medium, used for authenticating the user, is inserted, the authentication medium storing personal identification information of the user, a private key, and a software program for using the private key and,
• wherein the information processing apparatus comprises,
• a processor, implemented at least partially in hardware, for running the software program, to thereby establish a verified state in which the user is allowed to use the information processing apparatus;
• a signature processor that generates a digest from an input electronic document, the digest and the private key stored in the authentication medium being used to create a digital signature, which is to be attached to the input electronic document;
• and,
• wherein the information processing apparatus is further configured to change the verified state of the user having been established as a result of authenticating the user to a user unverified state after the digital signature is created and before the user is logged out from the information processing apparatus.
