Abstract
Provided is information processing apparatus, information processing method and a record medium, which can prevent occurrence of manipulation, in a case of accessing a memory, without consuming the access band of the memory. A main-processing unit, a sub-processing unit and a memory for loading a program are provided and process limit information stored in the memory is stored in storing means. The sub-processing unit judges whether a program to be executed is manipulated or not, and loads a program to be executed in the memory in case that the program is not manipulated. The sub-processing unit refers to the process limit information before execution of a program, and not permits execution of the program of the main-processing unit in case that a process by the main-processing unit for information stored in the memory accords with a process included in the process limit information.
