Database Security Using Multi-Shares Visual Cryptography

摘要

Security is a basic need of today's digital world. The Concept stated in this paper describes utility of Visible Cryptography (VC) to the authentication offacial pictures. In proposed system, photograph of character is taken care of, once entered it is encrypted and decrypted using sterilization set of policies. In this work useful bitwise operation is performed on every pixel with the help of key which is provided by new concept of sterilization algorithm. Initially it is necessary to separate the R, G and B channel from the image and which will be encrypted on Multiple shares and later to convert the image in such way that original image form only when shares are combined in proper sequence. In current innovation, the greater part of VC is implanted as a mystery utilizing various shares.
