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 (108, 326, 804 906, or 1108). A first mechanism (102, 302, 902, or 1102) is provided for obtaining a set of manufacturing errors (202 or 802) inherent in an optical media instance (200, 306, 800, or 1106). These errors can be encoded into the o-DNA that can be cryptographically signed with a private key (320), then embedded into the source optical media instance. A second mechanism (908 or 1110) 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.
