Blockchain and Biometrics: A First Look into Opportunities and Challenges
It addresses the problem of enhancing security and efficiency in biometric systems for researchers and practitioners, but is incremental as it provides an overview and discussion without new empirical results.
This study explores the potential of combining blockchain and biometrics to transform operations into faster, more secure, and cheaper approaches, focusing on opportunities, challenges, and blockchain for biometric template protection.
Blockchain technology has become a thriving topic in the last years, making possible to transform old-fashioned operations to more fast, secured, and cheap approaches. In this study we explore the potential of blockchain for biometrics, analyzing how both technologies can mutually benefit each other. The contribution of this study is twofold: 1) we provide a short overview of both blockchain and biometrics, focusing on the opportunities and challenges that arise when combining them, and 2) we discuss in more detail blockchain for biometric template protection.
