Multiple image sharing scheme for secure communication

Abstract

This paper proposes a multiple image sharing scheme for secure communication of multiple images. The proposed scheme is applied for digital information data to provide a secure transmission, in such a way that only receiver get appropriate information. The proposed scheme, secretly generates n number of shares for multiple images by applying the matrix multiplication and matrix addition method with the help of random matrix under the deformation algorithm in such a way that single share does not reveal any information about the secret images. Receiver only get shares of secret images and a subset of shares is used to identify the secret images. A reformation algorithm is proposed in this work which work on the basis of pixel and manipulation through matrix addition. The proposed algorithm is also applicable for threshold (k, n) secret sharing scheme that is used for reconstruction of the images at receiver end where k ≤ n or shares are clubbed to get secret images. The proposed method is capable of producing images as an output with same size, pixel, contrast and applicable for all types of images (grayscale, binary, colour). Experimental results shows that the proposed scheme is efficient, simple and secure for transferring images in wireless mode.
