Abstract
An information processing apparatus is disclosed that includes an expiration detection unit that detects expiration of a certificate used for verifying the validity of software; a software verification unit that verifies the validity of the software using the certificate; and a storage unit in which the certificate is stored. In the apparatus, the software verification unit previously stores a value uniquely calculated from the software in the storage unit when the certificate has not expired and the software is valid, and verifies the validity of the software using the value uniquely calculated from the software where the certificate has expired or the software is invalid.
