This paper presents an image encryption scheme for secure digital images based on secret sharing and coupled map lattices. In this scheme, the secret image is encrypted before the sharing phase based on key sequences generated by chaotic map lattices. Experimental results and analysis show that the proposed scheme has better security and can be easily protects both confidentiality and loss-tolerance simultaneously in shadow images.
