A Review Paper on Development of Visual Cryptography Technique for Authentication Using Facial Images

Bhagyashri P. Kandalkar [2] | G. D. Dalavi


Abstract: Cryptography refers to the study of science and art for achieving security by encode the messages to make them the data is not readable. For example the readable message is converted into an unreadable message by using cryptographic system and this process called well-structured and systematic. The Cryptography is basically securing the data during the communication between different systems. To provide the security of data during communication in cryptography we together require the Algorithm and Key. In this project, I am presenting a novel technique of in the Development of Visual Cryptography Using low complexity algorithm and bit shifting which image is encrypted at multiple levels using low complexity and bit shifting algorithm method. In encryption secret image is converted into monochromatic image i. e. Red, Green and Blue channels are separated and each channel encrypted using low complexity and bit shifting algorithm. It is a bitwise operation. In this project a modified approach is being proposed for increasing the security of the data. For increasing the security we are basically concentrating on the key part of the cryptography we basically uses the Low complexity and bit shifting algorithm which is designed by the user. Shares obtain at each level are stored in database using that database image is encrypted to further levels. For decryption all the shares are need to be superimposed in proper sequence using these two algorithms. Sender encrypts the message using the secret key and then sends it to the receiver. The receiver decrypts the message to get the secret information. Visual Cryptography (VC) is a technique which encrypts the image and converts it into unreadable format with the help of key by decrypting the image we get original secret image. This paper provides a higher level of security for Development of visual cryptography technique for authentication using facial images.
