A new (k, n) natural secret image sharing scheme based on Boolean XOR operation to improve the secret image security is presented in this research paper.A natural secret image is encrypted into n meaningless noise-like shares by using a random image of same size as original secret, Boolean XOR operations and circular shifting operations.A distinct identifier is used for each share image by swapping bits of a random number during encoding stage.These share images are transmitted over communication channel.The secret image is reconstructed at the receiving end by using at least k or more number of share images with little computations of Boolean XOR operations and circular shifting operations.The proposed scheme is suitable to gray-scale and color images.The experimental results and comparisons give feasibility and consistency of proposed scheme.
