0302-9743 arance in the academic community in the early 1990s, great progress has been made in understanding both the capabilities and the weaknesses of digital watermarking. On the theoretical side, we all are now well aware of the fact that digital watermarking is best viewed as a form of communication usin

In each category, some prominent representatives are selected. The principles, merits, drawbacks and applications of these algorithms are analyzed and addressed.

As a result, the watermark visibility is noticeably decreased, while at the same time enhancing its energy. The theoretic analysis of the detector is done to illustrate the affect of the filter on detection value. And the experimental results prove the effectiveness of the new approach.

Rudolf Egg,Cathrin Schauer,Peter K?hler transcoding. We analyzed the effect of video transcoding for watermark signal. Based on the analysis, metadata based approach is proposed to keep watermark in the video transcoding under QoS guaranteeing service environment. We performed experiments with widely used watermark algorithms to verify that the proposed watermarking system is useful.

In this study, the existing reversible data hiding algorithms, including some newest schemes, have been classified into three categories: 1) Those developed for fragile authentication; 2) Those developed for achieving high data embedding capacity; 3) Those developed for semi-fragi

Informed Detection Revisited detection, recent work has focused on blind detection, because it is considered more challenging and general. Further, recent work on “dirty-paper watermarking” has suggested that informed detection provides no benefits over blind detection..This paper discusses the dirty-paper assumptions and ques

A Counter-Geometric Distortions Data Hiding Scheme Using Double Channels in Color Imagesby a 6-parameters affine transformation. Our scheme is designed for color images, which is combined with error-correcting code, double-channels steganography, feature point extraction, and triangle warping. Two color spaces of RGB images are considered two independent channels, one for synchronizati
