Abstract
Visual Cryptography is an exciting area of research and is widely being used in diverse applications such as online banking, internet voting, cloud computing, biometrics, etc. It is one of the powerful encryption tool that can be used to hide visual information and can be decrypted by the human-visual system without requiring the use of any decryption technique. This paper examines the vital aspects of visual cryptography and analyse the findingsafter going through an extensive literature review. The major emphasis of present study is to highlight the key visual cryptography schemes and recent advances in the area of visual cryptography.
