Methods, apparatus and computer program products implement embodiments of the present invention that include loading a digital model to a digital manufacturing system having a manufacturing tolerance, and manufacturing, by the digital manufacturing system using the digital model, multiple objects. For each given object, one or more fingerprint measurements of the given object are collected from a fingerprint sensing device having a fingerprint resolution better than the manufacturing tolerance, and using the one or more fingerprint measurements, a unique digital fingerprint is created. The unique digital fingerprint can be stored to a provenance database. Subsequent to storing the unique digital fingerprints, one or more authentication measurements of an authentication object can be collected, and using the one or more authentication measurements, an authentication digital fingerprint can be created. The authentication object can be authenticated by locating a given unique digital fingerprint in the provenance database matching the authentication digital fingerprint.
