Classification: CPC G | IPC G

Claim 5:
6. The method of claim 1 wherein extracting a characterizing first digital fingerprint based at least in part on the first stereo image data includes:
creating a three-dimensional map of the interior portion of the first physical object, the three-dimensional map including multiple slices of the physical object that are obtained at different depths, at least one slice of the multiple slices including a plurality of points of interest;
converting the three-dimensional map into a digital representation of the interior portion;
generating the first digital fingerprint of the first physical object based on the digital representation, the first digital fingerprint of the physical object including an aggregation of the characterizations of points of interest in each of the multiple slices; and
storing the first digital fingerprint to a non-transitory computer-readable storage medium for at least one of subsequent authentication, tracking, grading, and identification.
