Visual Cryptography is based on cryptography

where n images are encoded in a way that only the human

visual system can decrypt the hidden message without any

cryptographic computations when all shares are stacked

together. This paper presents an improved algorithm based

on Chang’s and Yu visual cryptography scheme for hiding

a colored image into multiple colored cover images. This

scheme achieves lossless recovery and reduces the noise in

the cover images without adding any computational

complexity.
