Abstract
To improve security and robustness of digital watermarking algorithm, after studied various advantages and disadvantages of the common watermarking algorithm, this paper proposed an improved chaotic mixing algorithm based on the concept of Rubik's cube for watermarking images.First of all, obtained noise signals from the original watermark by the Rubik's cube algorithm to improve the security.It combined with DCT, DWT and SVD in embedding the watermark in order to improve the invisibility and robustness.Experimental results show that the algorithm has good robustness against noise, normal image processing,image compression,and also has invisibility.关键词
