Biometric Authentication Systems: Security Concerns and Solutions

Biometrics is a measure of unique and permanent physical or behavioral traits of an individual. As they are unique, they are more reliable in verifying a claimed identity. The Biometric Authentication System is an emerging domain that provides an efficient solution in improving digital security. Biometric authentication is the identification and verification process to determine the identity of a user by measuring characteristics like voice, iris, face, fingerprint samples. Even though Biometric Authentication Systems are better than traditional PIN/Password based authentication systems in most aspects, they are vulnerable to attacks. This paper is an overview of such security concerns of Biometric Authentication Systems, and their possible solutions.
