Abstract:
Embodiments of the invention are directed to a method and resulting structures for identifying an integrated circuit (IC) chip using optically-unique features. In a non-limiting embodiment of the invention, an imaging device generates an image of the chip. One or more optical features of the chip within the image can be determined and stored in a local or remote database. Metadata associated with the chip can be generated and linked with the one or more optical features of the chip and a unique identifier of the chip in the database.
