Digital watermarking can be used to protect the intellectual property for multimedia data. In this paper, we introduce an image watermarking scheme based on the SVD (Singular Value Decomposition) compression. In particular, we divide the cover image into blocks and apply the SVD to each block; the watermark is embedded in all the non-zero singular values according to the local features of the cover image so as to balance embedding capacity with distortion. The watermarking system we propose is robust against typical attacks, including low-pass and high-pass filtering, as evaluated by the Checkmark benchmarking tool [19]. Copyright 2006 ACM.
