Abstract
It is an object of the present disclosure to improve robustness against an unintended alteration in data in a volatile memory. An information processing apparatus has a storage unit storing two or more boot programs; a determination unit configured to determine the validity of each of the boot programs; an information generation unit configured to generate volatile information; and a selection unit configured to extract the volatile information at random, selects one of the boot programs on a basis of the extracted volatile information, and in a case where the determination unit determines that the selected boot program is not valid and that another one of the boot programs is valid, perform a process of overwriting the selected boot program with the another boot program.
