Effective Cryptosystem Scheme Using Biometric Template

Abstract—Nowadays security is an important issue. Encryption and Decryption is a technique to ensure the security. Having secure and reliable means for communicating with videos and images is becoming a very necessity and its issues must be carefully considered. Hence, network security and data encryption have become important. Nowadays the images and videos are the most usable forms of encryption. There are two types of applications for information transmission over the Internet. The first ones are the online applications and next ones are the web pages, which consider the speed and security respectively as the main issue. In this thesis, encryption algorithms that can fulfil the requirements of these two applications were studied, and were adjusted to meet the requirements of image encryption by using the bio-metric template i.e. palm print. Bio-metric authentication systems are widely used in order to provide authentication without possessing any physical materials. Bio-metric authentication systems are mainly concentrating on security, privacy, and accuracy. In this thesis, propose a provably two way secured biometric authentication system, which concerns of user’s privacy, protection, trust issues, network security, and accuracy. The two way secured means, biometric details are going to be encrypted twice i.e. double encryption. In this system two different encryption algorithms have been used. One is private key cryptography another one is public key cryptography. Authentication by using two way encryption will give additional security when comparing with existing system
