State-of-the-Art Visual Cryptography Schemes

Mahmoud E. Hodeish; Dr. V. T. Humbe

Visual Cryptography (VC) is recent technology used to the strengthen security of many applications in various fields. It allows visual information like printed text, handwritten notes, and images to be encrypted by dividing it into shares. The most important characteristic of VCS is that one can visually decrypted the secret image by stacking shares without computation. The current paper aims at introducing a descriptive review for VC, which covering the "state-of-the-art" concept, and classification of schemes. In this paper, we have classified the VC schemes and provide some interpretation on the base of some various measures such as pixel expansion, share generated, format of secret image and number of secret image, which actually deemed as valuable contribution in the field of VC studies.
