摘要

To provide an information processing device capable of performing self-authenticity determination with high accuracy.SOLUTION: An authenticity determination unit 50 comprises: a current value acquisition unit 52 for acquiring a plurality of actual measurement current values measured by a current measurement unit at a plurality of points of measurement timing from a current measurement unit; a pattern creation unit 53 for creating an actual measurement current value pattern by arraying the plurality of actual measurement current values acquired by the current value acquisition unit 52 in a time-series order; and a pattern comparison unit 54 for comparing the actual measurement current value pattern created by the pattern creation unit 53 with a reference current value pattern which has been created in advance for a genuine product. The authenticity determination unit 50 determines whether a host device 2 is a genuine product or a non-genuine product on the basis of a comparison result, obtained by the pattern comparison unit 54, between the actual measurement current value pattern created by the pattern creation unit 53 for a first prescribed period and the reference current value pattern which has been created in advance for a first prescribed period.SELECTED DRAWING: Figure 4
