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.
