Visual cryptography is a method to protect image-based secrets having less computation decoding process. In this technique, number of parts is generated from one image. The parts are sent to the destination and the original image is constructed by stacking all the share images. Different parts are generated for different types of images (binary, gray and color). Naor and Shamir introduced K out of K visual cryptography scheme which is a well known visual cryptography algorithm. In this study K out of N visual Cryptography (by permutation) is implemented using K out of K scheme. Experimental result shows the effectiveness of the approach.
