Abstract :
Reversible watermarking system with correlated watermarks and covertexts is studied. Necessary and sufficient conditions are derived such that the receiver can reproduce watermarks and covertexts within some distortions to original ones respectively, even watermarked signals are disturbed by an attacker. Furthermore, some interesting special cases are explored.
