Visual Cryptography Technique for Banking Application

Information is increasingly important in our day to day life. It gets more value when shared with others, .It is possible to share the information like audio, video and image easily, due to advances in technologies related to networking and communication. It may give rise to safety related issues. Attackers may try to access unauthorized data and misuse it. Certain techniques are required to solve this problem. For sharing information secretly, some techniques are used termed as Secret sharing schemes. When it comes to visual information like image and video, it is termed as Visual secret sharing scheme. A technique used for protecting image-based secrets is Visual cryptography (VC). In visual cryptography scheme secret image is split into some shares, which separately reveals no knowledge about the secret information. Then participants gets the shares. By stacking these shares directly, secret information can be revealed and visually recognized. To combine to reveal the secret image, all shares are necessary. Many visual cryptographic techniques have been evolved day by day.
