Abstract
In this paper a new (2, 2) visual cryptographic technique has been proposed, where the aspect ratio and the dimension of the secrete image/share with respect to source image remains constant during the process. In the VCTGLI technique grey level of some pixels of the input image has been inverted using random function to generate shares, instead of generating new pixels for shares. The scheme may be more secured and easy to implement like other techniques of visual cryptography.
To expound the effectiveness of the technique the obtained results are compared with the technique of Naor and Shamir [1], Yue and Chiang [2] and Jena and Jena [3] where it has been shown that VCTGLI gives better performance.
