Security, privacy, and usability challenges in selfie biometrics

Abstract

From biometric image acquisition to matching to decision making, designing a selfie biometric system is riddled with security, privacy, and usability challenges. In this chapter, we provide a discussion of some of these challenges, examine some real-world examples, and discuss both existing solutions and potential new solutions. The majority of these issues will be discussed in the context of mobile devices, as they comprise a major platform for selfie biometrics; face, voice, and fingerprint biometric modalities are the most popular modalities used with mobile devices.
