AB - This research aims to enhance photo encryption security by developing a sophisticated technique. This method uses homomorphic encryption to address challenges in encrypting visible spectrum pictures. Each red–green–blue (RGB) channel of the image is divided into smaller sub-values, encrypted separately using an optimized homomorphic encryption algorithm, and then combined for further encryption. Additionally, a novel approach involves combining surrounding pixels to embed extra data during encryption. The process allows for compression and decompression of encrypted components for easier storage or transmission. After decryption, the initial pixel values are recovered, removing any unnecessary data and condensing each channel's pixel intensity into just two sub-values. Multiple security evaluations confirm the method's robustness and resistance, emphasizing its strong security features for encrypted images.
