The paper proposes a grayscale images watermark authentication system based on SVD. The grayscale image is divided into the pieces of size 16*16. Each small piece is made into DCT transform and extracted low frequencies to generatethe watermark image. Then, the watermark image is made in Arnold scrambling algorithm and embedded in SVD algorithm. The hash algorithm is used to generate authentication code. In the authentication stage, when the image was tampered and attacked, the system can effectively lock the tamper region.
