Web based Biometric Authentication for data Security

Abstract

There is an increasing need for privacy and information security in present-day scenarios since sensitive information is being stored over internet. Cryptography is considered as an effective solution for ensuring security of data. To address certain limitations, cryptography and biometric combined. The system is known as Cryptobiometric system. Cryptobiometric system which uses biometric traits to protect or generate cryptographic hash. But hash generation based on biometric has some problems with privacy of biometric and revocability of biometric. Hence, there is a need to generate an efficient crypto-biometric system which satisfies privacy and revocability of biometric data. Authentication is the act of proving identity of a computer system user. In contrast with identification, the act of indicating a person or thing’s identity, authentication is the process of verifying that identity.  The Authentication techniques are classified into three, i) Knowledge based ii)Property based iii) Biometric based. This project is to generate a cryptographic hash from cancellable fingerprint template. Authors propose Cartesian transformation to induce cancellable template from fingerprint template of users. The generated hash value is used for authentication purpose.
