چکیده مقاله:
With the rapid development of information technology piracy is more prominent. Digital watermarking is a new technology to protect the legal owner’s copyrights. Inthis paper, we introduce a blind watermarking algorithm based on DCT and DWT. Using middle frequency band of DCT and 2-levels DWT provides better imperceptibility.Furthermore by using ARNOLD transformation the robustness and security of watermark image is increased. Theresults show that the proposed method have better performance with respect to DWT-Only method. Therefore, the proposed method has enhanced imperceptibility ofwatermarked image and robustness of watermark image against image processing attacks
