Abstract :

Secret images in Conventional visual secret sharing are hidden in shares that are either encoded and stored in digital form or printed on transparencies. The shares can be meaningful images or noisy like image, which may arouse suspicion and may be intercepted. Thus VSS Schemes are risky for the participants who are involved and even for the secret. In order to counter the above problem natural image based VSS Scheme is used that shares the secret image through various communication media to safeguard the participants and the secrets. In (n, n) NVSS scheme, one Secret image is shared over n-1 randomly selected natural images (natural shares) and one noise like image .The secret image and natural shares (in print form) generates the noise like image. The Natural Shares are commonly found and diversity of their selection drastically reduces the suspicion. The system may be made more efficient by introducing the concept of Encryption then Compression(ETC) unlikely the concept of compression then Encryption(CTE).After generating the noise like image by encryption ,it is hidden the compressed and transmitted. The process is reversed at the receiver end. Thus combination of (n, n) NVSS Scheme and ETC gives excellent solution for transmission risk problem.
