For digital image transmission security and information copyright,a new holographic image self-embedding water-marking encryption scheme is proposed.Firstly,the plaintext is converted to the RGB three-color channel,the correspond-ing phase hologram is obtained by holographic technology and the watermark is self-embedded in the frequency domain.Secondly,by applying the Hilbert transform principle and genetic center law,a complete set of image encryption algorithms is constructed to realize the encryption of image information.Finally,simulation results and security analysis indicate that the scheme can effectively encrypt and decrypt image information and realize the copyright protection of information.The introduced scheme can provide some support for relevant theoretical research,and has practical significance.
