Security and Privacy in Biometrics: Towards a Holistic Approach

Abstract

Security and privacy in biometric systems have been traditionally seen as two requirements hindering each other. Only in the recent past researchers have started investigating it as a joint optimization problem which needs to be tackled from both a legal, procedural, and a technological point of view. Therefore in this chapter we take a holistic approach and we introduce some basics about the privacy and the security issues which can affect a biometric system and some possible mitigation approaches, both procedural and technological, that can help in designing secure and privacy compliant biometric based recognition systems.
