Abstract :
In this paper, a verifiable copyright-proving scheme based on lifting wavelet transformation is proposed. Our scheme uses lifting wavelet transform (LWT) and chaotic system on the protected image in order to generate a verification map. Using the verification map, anyone can publicly verify the copyright of the protected image without needing the original image. Experiments show that the scheme can resistant geometric distortions and some intentional attacks. Without modifying the original image, the scheme is not only a robust method but also a lossless one.
