Content-Adaptive Semi-Fragile Watermarking for Image Authentication
Mohammed Ebrahim Al-Mualla · 2007
This paper presents a content-adaptive semi-fragile watermarking method for image authentication. The method is based on the semi-fragile watermark of Lin, Podilchuk, and Delp. However, the proposed method adapts the strength of the watermark and the detector type according to the content features of the image. Simulation results show that the proposed method outperforms the original method providing lower false positive detection rates.
