Design and Analysis of Secured, Revocable Iris based Biometrics Authentication System

In the present scenario, the major concern in today's society is about securing information and providing personal privacy. Researches from decade proven that Biometric authentication systems are commercially spreading and widely used for large scale authentication systems. Due to this, there is an immense growth in biometric authentication systems for data protection. This paper is mainly concerned about protection of biometric templates generated and stored in the system to avoid the misuse of these templates by fraudulent user in order to access the data of the legitimate. We make use of chaotic logistic maps, to obtain highly random keys which are highly sensitive to initial conditions, for providing security to iris templates.
