Security Evaluation of Behavioral Biometric Systems

Abstract

For establishing trust in the security of IT products, security evaluations by independent third-party testing laboratories are the first choice. In some fields of application of biometric methods (e.g., for protecting private keys for qualified electronic signatures), a security evaluation is even required by legislation. The common criteria for IT security evaluation form the basis for security evaluations for which wide international recognition is desired. Within the common criteria, predefined security assurance requirements describe actions to be carried out by the developers of the product and by the evaluators. The assurance components that require clarification in the context of biometric systems are related to vulnerability assessment. This chapter reviews the state of the art and gives a gentle introduction to the methodology for evaluating the security of biometric systems, in particular of behavioral biometric verification systems.
