Robust Image Sharing Scheme Using One Dimensional Chaotic Logistic Map

Abstract

In today’s world, image sharing has been a vital area of digital industry. Images are transmitted over an insecure transmission channel and are vulnerable to possible attacks. In this paper, we propose a novel technique for secure transmission of images. The method consist of two phases. In the first phase, user has to input a key of 256 bits. Arithmetic mean of the image and chaotic logistic map is used to generate key image. In the second phase, two layered Shamir’s secret sharing scheme(SSS) architecture is used with cascading XoR operation. Receiver can get the secret image back by applying reverse of the proposed method and secret key transmitted through the same insecure channel. In contrast to the previous schemes, our proposed scheme provides better utilization of bandwidth and robust against different possible attacks.
