Abstract
Apparatuses, methods, and systems are disclosed for heat-based authentication. An apparatus includes a processor and a memory that stores code that is executable by the processor. The code is executable by the processor to capture a thermal image of an object placed within a heated environment, identify at least one characteristic of the object based on the thermal image, and determine an authenticity of the object based on the at least one characteristic.
Claims20
An apparatus comprising:
- a processor;
- a memory that stores code executable by the processor to:
- capture a thermal image of an object placed within a heated environment that is configured to uniformly heat the object;
- identify at least one characteristic of the object based on the thermal image, the at least one characteristic comprising a heat-responsive feature that is intentionally incorporated into the object and known prior to capturing the thermal image;
- and
- determine an authenticity of the object based on the at least one characteristic by comparing the thermal image to a reference thermal signature previously linked to the object in a secure data structure.
