Enhancing Security in Biometric Authentication Systems using Dynamic Third-factor

Abstract

The use of biometric data for authentication in a networked environment brings both security guarantee and fear to many. It poses strong authentication because of its uniqueness; however, unlike passwords and smartcards, biometric information is non-repudiable. Therefore, it should be treated with utmost confidentiality and protection. Authentications hould be improved further because as people and machines advances the designs of security approaches and mechanisms, the threat increases in volume and variability also. In this paper, a dynamic third-factor authenticator for Biometric Authentication Systems is proposed. Not only that it protects biometric information, it also possesses the quality of dynamism that ensures security by addressing the threat before it takes place. This proposed enhancement follows the standards and guidelines prescribed for digital identity and data security.
