Abstract

This paper investigates the distortion-free robust watermarking by multiple marking. Robust watermarking is first performed. Then, by reversible watermarking, the information needed to invert both the robust and the reversible watermarking is embedded. In case of no attacks, the robust watermark is detected and the authorized party exactly recovers the original. In case of attacks, one can suppose that the robust watermark can still be detected, but the reversibility is lost. The approach relies on the embedded capacity of the reversible watermarking. The overall scheme inherits the robustness of the ?rst marking stage. The selection of the robust and of the reversible watermarking schemes is discussed. In order to improve the robustness of the first marking stage against the second one a joint marking procedure is proposed. A case study of reversible watermarking providing very good robustness against JPEG compression is presented.
