Abstract

Biometric authentication due to its merits compared to traditional authentication methods like password finds its application in several crucial applications like border security, military, network security and forensic applications. However, biometric authentication systems are subjected to several attacks. Providing security to biometric template is an important issue in any biometric authentication system. Different biometric template protection mechanisms are in practice. Anyhow, no single method provides all the required properties of a biometric template. Hybrid template protection mechanisms are better compared to single biometric template protection mechanism. This paper presents a survey of different works that provides hybrid biometric template security.

Abstract

Security is an important component in any authentication system. Biometric authentication is gaining much importance in the current linked scenario. Anyhow, biometric based authentication systems are subjected to a variety of attacks. Stored biometric template attack is one of the severe attacks. Biometric template plays a vital role in biometric authentication. Therefore, ensuring security to biometric template is a demanding issue in the present times. Fuzzy vault is a crypto biometric frame work that provides security to biometric templates. This paper presents a survey on the different work done on fuzzy vault scheme to protect biometric templates.

Abstract

Crypto biometric systems are authentication systems where the concept of biometric authentication is blended with cryptography. Crypto-biometric systems utilize the advantages of biometrics over traditional password based authentication. This paper uses the idea of fuzzy vault cryptographic constructs to protect crucial data like secret encryption key. Fuzzy vault is a proven emerging technology for providing biometric template security. This work constructs two independent fingerprint and iris vaults and a combined multimodal biometric vault. The proposed multimodal biometric fuzzy vault uses the features extracted from both finger print and iris for ensuring high security of the critical data and the biometric template. It is comparatively difficult for an attacker to compromise multi modal biometric fuzzy vault system than single biometric fuzzy vault systems. This work measures the security of the constructed fuzzy vault by means of min-entropy.

Abstract

Keyboard Entropy is a feature, which will try to identify the authenticity of a user when the user is working via a keyboard. The authentication process is done by observing the change in the entropy of the user. The objective of the paper is to design and implement a biometric authentication scheme by means of keyboard entropy to secure all applications, which require password authentication. Username and password pairs as authentication factors are as weak as they are ubiquitous. Use of a single factor of authentication is so weak that multi factor authentication methods are required. The tolerance factor provides a bit of leniency to check the authenticity of user. It is introduced in the master data depending upon how much deviation is caused by the user at different times. This paper proposes two formulae for calculating tolerance value which generates False Acceptance rate (FAR) and False Rejection Rate (FRR).

Keywords
