Abstract
Information security is the most important part in the research and development area, government, industry, organization, etc. Recently, cybercrime or related hacking problem increase more and more. So high security is required to secure the information and/or image. Visual Cryptography Scheme (VCS) is a one of the technique to secure the information using simple algorithm while in some other security technique complex algorithm was used. VCS have a simple encryption algorithm which is secure information converting into the different shares and for the decryption process do not required any type of devices or any complex decryption algorithm. Decryption process is done using Human Visual Scheme (HVS). Circular Random Grid shares is better than the rectangular shares because functionality is increased by secure multiple information in circular random grid to provide the confidentiality. In the proposed scheme, secret sharing scheme is that secret information is divided into various meaning full and meaningless shares and is further recovered by superimposing processing and it is seen by HVS. In this Research we are describe every methods of VCS and presented its comparative study using advantages and disadvantages.
