摘要：

This paper proposes implementation of digital image watermarking using 3-level discrete wavelet transform. In this experimentation, digital image watermarking algorithm uses discrete wavelet transform (DWT) for decomposing cover image and watermark image. A defined algorithm does not change any information of the cover image. Information obtained from low frequency DWT coefficient of cover image and the watermark image is being used in order to get watermark embedding. Watermark extraction has been simply done by wavelet decomposition of watermarked image and cover image.
