Modified LSBR and Pixel Sieve Technique to in Visual Cryptography for Multiple Colored Images

Abstract Visual cryptography is a method for protecting image-based secrets that has a computation-free decoding process. In this paper we propose a new color visual cryptography scheme. Pixel Sieve method was proposed recently to encode an image into shares. Our proposed method suggested a way to encrypt multiple color images using symmetric key encryption procedure where we are using the idea of LSBR and pixel sieve method in a modified way. The proposed method is applied on several images and showed good result without any distortion. The algorithm proposed by this scheme reduces a considerable time for encryption and decryption in a much easier way and ensures the lossless transmissions of images.
