Abstract

An information processing apparatus holding a secure chip includes a determination unit that determines whether the information processing apparatus returns from an idle state; a detection unit that, if the determination unit determines that the information processing apparatus returns from the idle state, detects initialization of the secure chip before starting application software; and a control unit that, if the detection unit detects the initialization of the secure chip, controls an operation of the information processing apparatus so that a hash value of the application software is not registered in the secure chip that is initialized.
