ELECTRONIC CIRCUIT COMPONENT AUTHENTICITY DETERMINATION METHOD
First Claim
1. An electronic circuit component authenticity determination method, comprising:
- operating an electronic circuit component under a predetermined condition at a time of manufacturing or initialization of the electronic circuit component, measuring a waveform of one of power consumption and an electromagnetic wave at a time of the operation, and storing the waveform as first waveform data;
operating an authenticity determination target electronic circuit component under the predetermined condition, measuring a waveform of one of power consumption and an electromagnetic wave, and temporarily storing the waveform as second waveform data; and
comparing the stored first waveform data with the second waveform data, determining that the electronic circuit component is a genuine when the waveform data match, and determining that the electronic circuit component is a counterfeit product when the waveform data are different.

Abstract
This invention provides an electronic circuit component authenticity determination method capable of determining whether an electronic circuit component is a component manufactured by an authorized manufacturer. The electronic circuit component is operated under a predetermined condition at the time of manufacturing or initialization of the electronic circuit component. The waveform of power consumption or an electromagnetic wave at the time of the operation is measured and stored as first waveform data. An authenticity determination target electronic circuit component is operated under the predetermined condition. The waveform of power consumption or an electromagnetic wave is measured and temporarily stored as second waveform data. The stored first waveform data is compared with the second waveform data. It is determined that the electronic circuit component is a genuine when the waveform data match. It is determined that the electronic circuit component is a counterfeit product when the waveform data are different.
