Compartive Analysis of Visual Crptography Schemes

Visual cryptography is a technique to encrypt images, any handwritten notes or typed text which is in the form of images. Security is major aspect when transmitting information in modern era of information technology. Cryptography is basically uses the techniques of mathematics to provide the basic aspects of information technology such as confidentialities, data security, and authentication. The VCS is a method that hides a secret image by partitioning it into small parts. A distinguish property of VCS is that one can easily decrypt the encrypted image by superimposing parts without any mathematical computation as we did in cryptography.

In this work we are analyzing the different techniques in Visual Cryptography on parameters of security efficiency and computation techniques.
