A Digital Watermarking Technique with High Robustness Based on Content of Original Image in Wavelet Domain

In this paper a new digital watermarking technique is proposed based on discrete wavelet transform. In order to enhance the robustness of watermark, watermark was based on the content of the original image. Pesudorandom permutation, division and spectrum spread techniques were used to improve the robustness of watermark. Different from the traditional techniques, in our method, watermarks were emb…
