Optimization Algorithms in Visual Cryptography

EasyChair Preprint 3562

Abstract

Visual Cryptography is a cryptographic technique which intends to hide a secret within images. These images are encrypted into n shares and decrypted without computer calculations. In this work, we briefly describe a new proposed (n,n) Secret Sharing Scheme for grayscale/color images. We will approach the problem by two main algorithms: the algorithm of Cheng et al. and the deterministic (n, n) algorithm of Wang et al. We will modify them such that new obtained secret sharing scheme becomes more efficient and more secure. The scheme uses XOR operation sharing images, algebraic function for creating a secret image for authentication, while the size of the original image and shadows are the same. In the paper, we will make use of Cantor function, which makes possible the generation of respective codes for each participant.

Keyphrases: Cantor function, Secret image sharing, Visual Cryptography, XOR operation
