Thermal profiling to validate electronic device authenticity
First Claim
1. A method for determining whether an electronic device is authentic or counterfeit, the method comprising:
- running the electronic device under predetermined operating conditions;
monitoring a thermal profile of the electronic device;
comparing the thermal profile with an expected thermal profile;
determining the electronic device as authentic if the thermal profile has the expected thermal profile; and
determining the electronic device as counterfeit if the thermal profile lacks the expected thermal profile.

Abstract
Counterfeit electronic devices are detected by comparing a thermal profile of the counterfeit device and an authentic device under predetermined operating conditions. A thermal profile for an authentic electronic device is recorded executing an instruction set over time, such as with static infrared images at predetermined times, video infrared images over a predetermined time period or temperature measurements made at predetermined locations of the electronic device. In one embodiment, a thermal profile indicates that a processor device has been used in the place of a field programmable grid array device. In an alternative embodiment, an electromagnetic profile is detected instead of or in addition to the thermal profile. The electromagnetic profile of an authentic device is used to create an expected profile for comparison with an electromagnetic profile of electronic devices under test.

10. A system for identifying electronic devices as authentic or counterfeit, the system comprising:
- a thermal profile database having expected thermal profiles for one or more electronic devices under one or more predetermined operating conditions;
a thermal profile detector operable to detect a thermal profile of an electronic device under test; and an authenticity module interfaced with the thermal profile database and the thermal profile detector, the authenticity module operable to compare a thermal profile of the electronic device under test with an expected thermal profile to identify the electronic device as authentic or counterfeit by determining the electronic device as authentic if the thermal profile has the expected thermal profile; and
determining the electronic device as counterfeit if the thermal profile lacks the expected thermal profile. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
