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.
