Abstract

A new transparent and robust watermarking method against JPEG compression attack based on a perceptual approach is proposed. The main idea is to embed the watermark into regions where the blocking artifact has no effect on the watermark. These regions are identified by using a spatial prediction model of blocking effect. A JND (Just-Noticeable-Difference) model is then used to control the embedding strength in order to ensure robustness and transparency of the watermarking. The performance of the proposed method is evaluated on a set of images and some common “signal processing" attacks.
