Reversible and Blind Database Watermarking Using Difference Expansion

International Journal of Digital Crime and Forensics, 2008
There has been significant research in the field of database watermarking recently. However, there has not been sufficient attention given to the requirement of providing reversibility (the ability to revert back to original relation from watermarked relation) and blindness (not needing the original relation for detection purpose) at the same time ...

Local-Prediction-Based Difference Expansion Reversible Watermarking

IEEE Transactions on Image Processing, 2014
This paper investigates the use of local prediction in difference expansion reversible watermarking. For each pixel, a least square predictor is computed on a square block centered on the pixel and the corresponding prediction error is expanded. The same predictor is recovered at detection without any additional information.
