1. A system that issues an optical DNA (o-DNA) signature to facilitate authentication of optical media, comprising:

  • an examination component that identifies error data that is limited to a set of non-deterministic manufacturing errors extant on an optical media instance, the examination component employs the error data to construct an error fingerprint representative of the optical media instance; and

    an issuing component that generates an o-DNA signature for the optical media instance based at least in part upon the error fingerprint.
