A novel technique for encoding images using Chen model and computer-generated holograms

Abstract In this work, computer-generated hologram technology was used to encode information and link it to one of the chaotic system models (Chen), using the Matlab program. The results showed that the information (images) can be easily identified using computer-generated holograms through the process of computer holographic reconstruction of the images to be encrypted, and this process is undesirable in secure communications, But when linking with the chaotic Chen system through several mathematical operations including addition, multiplication and division, the resulting holograms of the image to be encrypted and the hologram of the Chen system, where the results showed complete encryption of the images to be encrypted and the disappearance of their features using the division process.
