Abstract—Digital watermarking is a method for protecting copyrighted materials such as digital images. This paper presents a new color watermark embedding technique with circulation, based on non-overlapping Singular Value Decomposition (SVD) for hiding important information in images. First, the real-color original image is decomposed into three components R, G and B. The blue component and the watermark performed by Chebyshev chaotic map are divided into non-overlapping blocks, respectively. Then an SVD is performed on each partitioned blocks. Second, the Singular Values (SVs) of watermark are embedded into the singular value matrix of blue component with circulation. Extracting any consecutive four rows and columns from the blocked watermarked image can get complete watermark information. Every watermark bits have been embedded several times and their embedding position are consecutive in the selected original image. That is why, our proposed scheme is naturally secure to geometric attacks and compound attacks, and it is also strongly robust against common image processing attacks.
