Paper Abstract

Semi-fragile watermarking methods aim at detecting unacceptable image manipulations, while allowing acceptable manipulations such as lossy compression. In this paper, we propose new semi-fragile authentication watermarking techniques using random bias and non-uniform quantization, to improve the performance of the methods proposed by Lin and Chang. Specifically, the objective is to improve the performance tradeoff between the alteration detection sensitivity and the false detection rate.
