Assignee: ALITHEON, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. The system of claim 15 wherein to extract a characterizing first digital fingerprint based at least in part on the first stereo image data, the processor-executable instructions cause the at least one processor to:
create 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;
convert the three-dimensional map into a digital representation of the interior portion, the first digital fingerprint of the physical object including an aggregation of the characterizations of points of interest in each of the multiple slices;
generate the first digital fingerprint of the first physical object based on the digital representation; and
store the first digital fingerprint to a non-transitory computer-readable storage medium for at least one of subsequent authentication, tracking, grading, and identification.
