Abstract
Recently, digital multimedia contents can be easily accessed and modified by various digital technology. For protecting copyrights or intellectual properties of original data, digital watermarking technique has been attracted considerably. In this paper, we propose a robust watermarking scheme for digital images based on the lifting filters which provides a simple construction of second generation wavelets. The original image is transformed into wavelet domain by two sets of lifting filters; one is for usual wavelet filter, the other is for embedding watermarks whose locations are created randomly with secret key. We accomplish the Stirmark benchmark test(www.watermark.org) to demonstrate the robustness of our watermarking scheme to JPEG compression attacks, and others as well. 1.
