Biometric Modality Challenges and Future Prospects

Abstract

In this article, the challenges and future prospects in biometrics modalities are discussed. First, typical biometric modalities are introduced. Next, as current challenges in biometrics, a privacy issue and spoofing issues are discussed. For resolving the spoofing issue in system-user management, continuous authentication is necessary for which new biometrics modalities such as brain waves and intrabody propagation signals are introduced. Finally, as future prospects, smell- and taste-based authentication and some new perspectives on biometrics are introduced.
