An SVD-based Self-Embedding Watermarking Method for Image Authentication

This paper presents a new self-embedding watermarking method for image authentication, which extracts image features from the U component of the SVD domain to generate watermark. In the new method, the watermark generating and watermark embedding are disposed in the image itself, and the received image authentication needs no information about the original image or watermark. The method increases watermark security and prevents forged watermark. Experimental results show that the new method can identify intentional content modification and incidental tampering, and also indicate the location where a modification takes place
