A service program recorded on a portable medium is executed directly or after being installed temporarily in a long-term storage apparatus. A program execution device prevents unrestricted execution of the program when the portable medium is not inserted in the device, from the viewpoint of managing resource access to the device. The program is attached with permission information indicating resource access rights. According to an acquisition route of the program to be executed, first permission information and second permission information indicating different access rights are applied for executing the program.
