Abstract: An information processing system made up of a plurality of controllers in a vehicle has a tamperproof configuration by including, in a specific controller among the plurality of controllers: a starter putting the specific controller among the plurality of controllers in a executable state which enables the specific controller among the plurality of controllers to execute a preset program; a determiner determining, before the specific controller among the plurality of controllers is put in the executable state, whether software that is memorized in a preset memory area and at least includes the preset program is tampered; and an outputter outputting, to one of processing devices outside the vehicle. In such manner, the tampering of the software is quickly detectable while preventing an increase of communication load of a communication network and/or the information processing system.
