Digital image steganography has several applications in information security and
communication. Data hiding in encrypted images ensure that both the cover image and the
secret message can be recovered at the receiver end. This work presents a novel data
hiding and image encryption scheme using random diffusion andTwo dimensional Arnold
cat mapping transform. The secret message bits are placed in the least significant bit
positions of the cover image. Then a shared key is used to generate random 8 bit random …
