N2 - An innocuous visual secret sharing scheme over natural images is presented in this paper. Secret sharing scheme allows a group of participants to share a secret (i.e., an image) among them. In case of(k, n) visual cryptography any group of k qualified participants among n (where k ≤ n) can reconstruct the secret. This paper presents (n, n) visual cryptography scheme. This scheme does not apply dithering techniques to hide a secret image. Thus, it does not degrade quality of the secret image and in particular, this scheme is far from negative photo effect. Instead of dithering, this scheme spreads data by applying simple arithmetic operations. The rationale of arithmetic operations is presented.
