Abstract
An anti-counterfeiting technique presents, to a test thermoreflective mark at a first temperature, a first electromagnetic wave. A first test reflective profile for the test thermoreflective mark associated with the first temperature is recorded. A second electromagnetic wave is presented to the test thermoreflective mark at a second temperature. A second test reflective profile for the test thermoreflective mark associated with the second temperature is recorded. The first test reflective profile is compared with a first control reflective profile that is associated with a genuine thermoreflective mark. The second test reflective profile is compared with a second control reflective profile that is associated with the genuine thermoreflective mark.
