With the rapid development of information technology piracy is more prominent. Digital watermarking is a new technology to protect the legal owner’s copyrights. In this paper, we introduce a blind watermarking algorithm based on DCT and DWT. Using middle frequency band of DCT and 2levels DWT provides better imperceptibility. Furthermore by using ARNOLD transformation the robustness and security of watermark image is increased. The results show that the proposed method have better performance… CONTINUE READING
