Abstract
A system for detecting changes to circuitry includes: a processor; and a memory, and the memory has stored thereon instructions that, when executed by the processor, cause the processor to: periodically measure physical characteristic data of the circuitry, operational data of the circuitry, and environmental data; periodically capture the measured data; generate a dynamic fingerprint based on an aggregation of a first set of the captured data, and the dynamic fingerprint is a compound data structure encapsulating the aggregated data; associate metadata with the dynamic fingerprint; periodically update the dynamic fingerprint according to successive sets of the captured data; and compare the updated dynamic fingerprint to a previous dynamic fingerprint, to detect the changes to the circuitry.
