| On Authentication With Distortion Constraints (2001) | |||||||||||||||||
Abstract | |||||||||||||||||
| In many multimedia applications, there is a need to authenticate sources subjected to benign degradations such as noise, compression, etc., in addition to potential tampering attacks. Authentication can be enabled through the embedding of suitably chosen markings in the original signal. We develop one information-theoretic formulation of this problem, and identify and interpret the associated fundamental performance limits. | |||||||||||||||||
