Patent Number: 8,788,848

Title: Optical DNA

Abstract: The claimed subject matter relates to architectures and/or mechanisms that can facilitate issuing, embedding and verification of an optical DNA (o-DNA) signature. A first mechanism is provided for obtaining a set of manufacturing errors inherent in an optical media instance. These errors can be encoded into the o-DNA that can be cryptographically signed with a private key, then embedded into the source optical media instance. A second mechanism is provided that can decrypt the o-DNA with a public key and compare the authenticated errors to the observed errors to ascertain whether the optical media instance is authentic as opposed to a forgery or counterfeit.
