Abstract

In an information processing apparatus, a second central processing unit (CPU) uses an alteration detection program stored in a second memory to perform alteration detection on a program to be executed at a time of activation of a first CPU stored in a first memory. In a case where no alteration is detected in the program to be executed at the time of activation, the second CPU activates the first CPU using the program to be executed at the time of activation, and uses the activated first CPU to switch a program to be executed by the second CPU from the alteration detection program stored in the second memory to another processing program stored in the first memory.
