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 using information that is read from the memory device 20. The information processor 10 includes: a power controller 110 that supplies power to the memory device 20; a current measurement circuit 120 that measures consumption current that flows from the information processor 10 to the memory device 20; and determination means that calculates the amount of change of the consumption current per unit time as a change rate of the consumption current, and determines whether or not the memory device 20 is an authorized product on the basis of the calculated change rate. |
