Biometric Template Protection: A Systematic Literature Review of Approaches and Modalities

With the emergence of biometric authentication systems, template protection for biometrics captured attention in the recent years. The privacy concern arises due to storage and misuse of biometric data in various applications. This chapter systematically reviews the published literature on Biometric Template Protection (BTP) during 2005–2016 and covers the methods described in more than hundred articles. It aims to present the current status of BTP schemes by a methodical analysis and taxonomy of BTP approaches, modalities, the fusion of modalities (multi-modal), and hybrid methods. It also presents research implications and extraction outcomes of Systematic Literature Review conducted on BTP schemes. This research work helps researchers and practitioners to find relevant information on BTP methods thereby reducing time and complexity in searching the appropriate studies.
