This paper studied the image tamper detection and recovery watermarking scheme based on the discrete wavelet transformation(DWT) and the singular value decomposition (SVD).By the property of DWT and SVD , we design two watermarks which are embedded into the high-frequency bands of the DWT domain.One watermark is from the U component of the SVD domain and used for detecting the intentional content modification and indicating the modified location, and another watermark is from the low-frequency of DWT and used for recovering the image. The watermark generation and watermark embedding are disposed in the image itself. The experimental results show that the proposed scheme can resist the mild modifications of digital image and be able to detect and recovery the malicious modifications precisely.
