Visual cryptography by name itself suggests cryptography related to images. It is a branch of cryptography that deals with the encryption and decryption of images. Visual cryptography demonstrates a visual secret sharing scheme in which an image has been divided into n shares and original image can be decrypt with these shares without / less computational efforts. This paper proposed an efficient (n, n) visual secret image sharing method using random grids. This scheme gives the complete retrieval of secret image using XOR stacking without the need of a codebook. The Random Grid based Visual Cryptography results no pixel expansion. The proposed method works for (shares) for retrieval of original image. Experimental results demonstrate that the proposed method produces better results in terms of simplicity, visual quality and performance.
