Abstract

(k, n) visual cryptography is an important data hiding algorithm. Using Shamir's secret sharing, this paper shared a binary secret image into n meaningless shares in order to make the generated shares more like noise images, adding the randomness within the process of sharing. It picked any k shares from n meaningless shares and used Lagrange interpolation to reveal the secret image. This paper applied Shamir's secret sharing to realize a (k,n) visual cryptography, and it neither required code book nor suffered from pixel expansion. Experimental results show the proposed method can realize a (k,n) visual cryptography, and it guarantees correct decoding rate(CDR) of revealed secret image.
