The paper proposes a blind spread spectrum watermarking scheme where watermark information is embedded redundantly in the multilevel wavelet coefficients of the cover image. It ha...
This paper describes a robust watermarking algorithm and a collusion-secure fingerprinting scheme based on it. Watermarking robustness is obtained by using the JPEG algorithm to ...
This paper deals with the improvement of the Dirty Paper Trellis Code (DPTC) watermarking algorithm. This watermarking algorithm is known to be one of the best among the high rate ...
Digital watermarking studies have always been driven by the improvement of robustness. Most of articles of this field deal with this criterion, presenting more and more impressive...
Abstract. In this paper a novel theoretical security analysis will be presented for data hiding methods with side-information, based on Costa’s dirty paper scheme. We quantify th...
