Fusing watermarking and encryption for digital image based on homomorphic algorithm
We proposed a commutative watermarking-enceryption method for the purpose of protecting privacy and copyrights of digital image monitoring system.The method fuses watermarking and encryption based on the homomorphic addition.The method allows the certain permission level peerson to view special quality copies of remote monitoring images,verify the origin of images.There are two advantages of our method.The first one is robustness against JPEG compreession, Filtering and Geometric transfommations.The second one is controlling permission of visiblity.The method is theoretically proved semantically secure.Experirments showed the effectiveness and robustness.
