Evaluation methodology for fake samples detection in biometrics

Nowadays biometrics is being used in many applications where security is required. This fact causes that new threatens have appeared and that the number of attempts to break biometric systems has increased. From all potential attacks, those involving damage or thefts to users are the most worrying. Most of them could be avoided if acquisition sensors would have suitable approaches for aliveness detection at the capture process. Many providers claim that their products support these methods but unfortunately it has been discovered that some products do not detect fake samples. In this paper a methodology based on Common Criteria is given to evaluate, in an independent way, whether biometric capture devices implement methods for fake samples detection, and till which extent such methods are effective. This methodology has been tested with sensors from different modalities.
