Multimedia content authentication: fundamental limits

In many multimedia applications, there is a need to authenticate a source that has been subjected to benign degradations in addition to potential tampering attacks. We develop a meaningful formulation of this problem, and identify and interpret the associated information-theoretic performance limits. The associated systems are shown to perform dramatically better than frequently proposed approaches based on information embedding techniques.
