A New Digital Watermark Algorithm Based on the DWT and SVD

In this paper, we consider the application of the discrete wavelet transform (DWT) and singular value decomposition (SVD) in the digital watermark systerm. Based on this algorithm, it is efficient to protect the rights of the owners' digital content. This paper examines a technique for digital watermarking which utilizes properties of the DWT and SVD. The exeperimental results show that it is roubust against rotating, zoom, compression, adding noise, filtering and cropping.
