| Abstract: | To achieve the copyright protection of digital image,a digital watermarking algorithm based on DWT and image sharing is proposed.The watermarking is embedded the middle-frequency coefficients based on the randomly selected locations.The ECC technique and torus automorphism technique are also used to enhance the security of the watermarking algorithm.The numerous tests and the results obtained the superior performance of the proposed approach. |
