Threshold Based Region Incrementing Secret Sharing Scheme for Color Images

Authors: P. Mohamed Fathimal, P. Arockia Jansi Rani


In this era of online communication, which transacts data in 0s and 1s, confidentiality is a priced commodity. Ensuring safe transmission of encrypted data and their uncorrupted recovery is a matter of prime concern. Among the several techniques for secure sharing of images, this paper proposes a k out of n region incrementing image sharing scheme for color images. The highlight of this scheme is the use of simple Boolean and arithmetic operations for generating shares and the Lagrange interpolation polynomial for authenticating shares. Additionally, this scheme addresses problems faced by existing algorithms such as color reversal and pixel expansion. This paper regenerates the original secret image whereas the existing systems regenerates only the half toned secret image.

Keywords: Authentication, Access control, Steganography, XOR, secret image sharing, Threshold Secret Sharing Scheme, Pixel Expansion
