摘要：

This paper proposed a new robust digital image watermarking technique to protect the data. In this paper digital watermarking technique is proposed using median filter function based on discrete wavelet transform and singular value decomposition. Original image is passed through median filter function to make the image smooth, then first level wavelet transform is applied. Embedding is done in high frequency band by modifying the singular value of watermark and original image. Various techniques are proposed to hide the data but current technique shows robustness against various attacks.
