The overview of trends and challenges in mobile biometrics

Currently, various biometric modalities are used to perform human identification or user verification. Although the research results are promising, the constant development of biometric systems is needed. Recently, biometric systems are also implemented for mobile devices, services and applications. In this article, the review of current trends in mobile biometrics is discussed. The paper also describes the most challenging aspects like aging, template protection or wide users’ acceptance. Finally, palmprints are described as the trait that may give promising results and could be implemented widely in mobile biometrics.
