Claim 0:
1. A digital fingerprinting method, the method comprising:
acquiring first stereo image data of at least an interior portion of a first physical object;
extracting a characterizing first digital fingerprint based at least in part on the first stereo image data; and
inducting the first physical object into a reference database system by storing a record in the reference database system that includes the characterizing first digital fingerprint, wherein the characterizing first digital fingerprint includes characterizations of points of interest that are internal to an exterior surface of the first physical object and uniquely identifies the first physical object from other physical objects of a same type or class of physical objects as the first physical object based on intrinsic characteristics of the first physical object, including intrinsic characteristics of the interior portion of the first physical object, without relying on any tag, label, or other extrinsic identifier added to the first physical object for identification.
