The zero-bit watermarking technique uses the feature of images to generate watermarks to be authenticator of the digital multimedia, and makes host media without any distortion. It is highly desired in quality-sensitivity imagery, such as medical images and legal images, where even the small distortion introduced by embedding watermark is unacceptable. In this paper, we propose a zero-bit watermarking algorithm based on singular value decomposition (SVD) and digital wavelet transform (DWT). The… CONTINUE READING
