Summary:A new DWT (Discrete Wavelet Transform) algorithm is proposed based on data storage. Since the image data stored in the memory position with the image itself are unrelated. The focus of the research is on the image data in memory, relegating the traditional algorithm which is based on the entire image. The image data is divided into the appropriate data blocks, and DWT is carried out for each block independently. At the same time, taking into account the watermark invisibility and robustness and in order to improve the watermark safety and concealment, watermark is encrypted before embedding. Synthetic application of data segmentation, watermark scrambling and multi-resolution analysis in the algorithm is effected. Not only is watermarking invisible, but also has a better robustness for image processing such as noise, filtering, shearing, and so on.
