Abstract
A novel method for embedding watermarks into a host image in the frequency domain is proposed. Unlike the traditional techniques, the method addresses that watermark is embedded into the lower frequency. The watermark is self-extractable and the algorithm is simple. Experimental results demonstrate that the watermark is robust to various attacks.
