Information security is the most important part in the research and development area, government, industry, organization, etc. Recently, cybercrime or related hacking problems have increased more and more. So, high security is required to secure the information and/or image. Visual Cryptography Scheme (VCS) is one of the techniques to secure information using a simple algorithm, while some other security techniques use complex algorithms. VCS has a simple encryption algorithm which secures information by converting it into different shares, and the decryption process does not require any type of devices or any complex decryption algorithm. The decryption process is done using the Human Visual Scheme (HVS). Circular Random Grid extends its functionality by securing more information in a circular grid to provide confidentiality. In the proposed scheme, the methodology of the secret sharing scheme is that secret information is divided into various shares in meaningless form and is further recovered by overlapping these various shares using HVS. In this research, we describe every method of VCS and present its comparative study using advantages and disadvantages.
