An image encryption algorithm based on a 3D hyperchaotic map and non-uniform block-based hybrid diffusion

This paper presents a new image encryption method that uses a 3D hyperchaotic map (a mathematical system with unpredictable behavior in three dimensions) combined with non-uniform block-based hybrid diffusion (mixing image data in varying-sized chunks to scramble pixel values). The research proposes a cryptographic technique designed to protect images from unauthorized access by making them appear as meaningless noise.
