摘要 PROBLEM TO BE SOLVED: To provide a technique that makes it hard to copy a memory device.SOLUTION: A memory information protection system 1A includes: a memory device 20; and an information processor 10 that executes information processing. An information processor 10 includes: a current measurement circuit 120 that measures a consumption current that flows from the information processor 10 to the memory device 20; a change rate computing unit 1021 that calculates the change rate of the consumption current on the basis of the consumption current for a predetermined measurement period; a comparison computing unit 1022 that compares a comparison value which is used as a criterion of determination of whether or not the memory device 20 is an authorized product, with the change rate which is calculated by the change rate computing unit 1021, to output a comparison result that indicates whether or not the comparison value and change rate match with each other; and determination means that determines whether or not the memory device 20 is the authorized product on the basis of the comparison result.
