Novel self-embedding holographic watermarking image encryption protection scheme

Abstract

For digital image transmission security and information copyright, a new holographic image self-embedding watermarking encryption scheme is proposed. Firstly, the plaintext is converted to the RGB three-color channel, the corresponding phase hologram is obtained by holographic technology and the watermark is self-embedded in the frequency domain. Secondly, by applying Hilbert transform principle and genetic center law, a complete set of image encryption algorithm 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 therefore has practical significance.

Dynamical analysis of a new memristive map with offset boosting and extreme multistability

“…In recent years, chaotic systems have received much attention in the fields of communication encryption [22][23][24][25][26], and control optimization [27][28][29], due to the highly complex and unpredictable motion trajectories [30][31][32][33]. Among them, chaotic maps attract the interest of researchers due to the advantages of antijamming, easy numerical simulation, and implementation [34][35][36][37].…”

An extreme multistable circuit based on a new memcapacitor and a new meminductor

“…Among them, hyperchaos, intermittent chaos and multistability are well worth studying [28,29], thereof, multistable states are of great interest in the industry [30,31]. In conclusion, complex chaotic systems can emit anti-interference and complex chaotic signals [32,33], therefore have extremely promising applications in the field of engineering and secure communication [34][35][36][37][38].…”
