Biometry is a wide-used and pervasive approach to verify people identity, based on the presence of some unique characteristics, having precise properties (i.e. biometric characteristics). On the other hand, optical detection of random features is widely used for recognizing object authenticity. In this paper we explain how these two approaches are similar; random features can be seen as "fingerprint" of inanimate objects. Some parallelisms with well-known biometrics solutions are reported, to emphasize the similarity of the two approaches.
