| Abstract: | To prevent that existing single watermarking from being easily attacked and to enhance the security of the general encryption method of multi-watermarking,this paper proposes the algorithm of graded embedding multi-watermarking,based on encryption of hyperchaos.This algorithm of graded embedding multi-watermarking uses hyperchaos sequence to encrypt multi-watermarking,graded embedding of multi-watermarking in original image.In the process of extracting watermarking,this graded Embedding multi-watermarking a... |
