Abstract
An information processing device having an activation verification function comprises: a module recording portion which stores plural system programs, a security chip having the function of checking the validity of the system programs and a verification portion which inspects the activation states of the system programs. The security chip executes validity checking processing using verification data provided by the system programs. If the security chip cannot confirm the validity of the system programs, the verification portion acquires activation-state information about activated system programs from the activated system programs. If pre-stored verification-information initial values for valid system programs and the acquired activation-state information match with each other, the verification portion determines that the current activation states of the system programs are valid, and the subsequent activation processing for the system programs is advanced.
