Reversible watermarking scheme with image-independent embedding capacity [PDF]
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Phase watermarking of digital images
Proceedings of 3rd IEEE International Conference on Image Processing, 2002 A watermark is an invisible mark placed on an image that can be detected when the image is compared with the original. This mark is designed to identify both the source of an image as well as its intended recipient. The mark should be tolerant to reasonable quality lossy compression of the image using transform coding or vector quantization.

ICA for watermarking digital images [PDF]
J. Mach. Learn. Res., 2003 Summary: We present a domain-independent ICA-based approach to watermarking. This approach can be used on images, music or video to embed either a robust or fragile watermark. In the case of robust watermarking, the method shows high information rate and robustness against malicious and nonmalicious attacks, while keeping a low induced distortion.
