An SVD-Based Watermarking Method for Image Authenticion

For image content authentication, a secure self-embedding watermarking method based on the singular value decomposition (SVD) is proposed. In the proposed 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. By adjusting the threshold of the detector, a trade-off between the robustness to JPEG compression and the probability of miss detection can be made. The proposed method is robustness and can detect a tampered area with high sensitivity. This is confirmed by experimental results.
