Secret Image Sharing Using Pseudo-Random Sequence

We propose a new concept which is derived from the cryptography, the substitution of bits in the image and the visual cryptography method. Given some secret data and a set of cover images, in the proposed scheme the secret data is encrypted by the administrator, after that we select the random bit planes of the cover images using the pseudo-random sequence and modify the cover image based on these random bit planes. In our method each participant has a unique modified cover image called stegoimage. Therefore these participants are required to reconstruct the encrypted secret data without destroying of its secrecy. After that administrator decrypt the original data. Experiments show the good quality of the stego-image. The proposed scheme also prevents anyone if steal all the shares will not gaining information about the secret data.
