From Weak to Strong Watermarking
The informal goal of a watermarking scheme is to “mark” a digital object, such as a picture or video, in such a way that it is difficult for an adversary to remove the mark wit...

On the Possibility of Non-invertible Watermarking Schemes
Recently, there are active discussions on the possibility of non-invertible watermarking scheme. A non-invertible scheme prevents an attacker from deriving a valid watermark from a...

Bit-plane watermarking for zerotree-coded images
In this paper, we develop a robust bit-plane watermarking technique based on zerotree coding. A robust watermark is an imperceptible but indelible code that can be used for owners...
