Numeric-Passcode Keystroke Biometric Studies on Smartphones

A keystroke biometric classification system traditionally used on data captured from physical keyboards associated with laptops and personal computers, was extended to evaluate biometric data extracted from mobile devices. The results were compared to the results of similar studies utilizing the same data inputs. Additional results were extracted; including results tied to features native to mo...

Advanced Studies on Reproducibility of Biometric Hashes

The determination of hashes based on biometric data is a recent topic in biometrics as it allows to handle biometric templates in a privacy manner. Two main applications are the generation of secure biometric templates and cryptographic keys. Depending on these applications, there are different requirements with regard to possible errors. On one side, authentication performance based on biometr...

Studies of Biometric Fusion NISTIR 7346; Appendix E: Modeling Biometric Score Distributions

This report discusses lessons learned in the course of developing models of score distributions from large samples of data using kernel density estimation techniques. The methods detailed here were used in the implementation of the Product of Likelihood Ratios and FAR-based fusion techniques. Studies of Biometric Fusion

Studies of Biometric Fusion NISTIR 7346; Appendix C: Evaluation of Selected Biometric Fusion Techniques

This report summarizes and evaluates several common score-level biometric fusion techniques. The literature contains numerous proposals for score-level biometric fusion algorithms. Selecting the most effective fusion techniques depends on operational issues such as accuracy requirements, availability of training data, and the validity of simplifying assumptions. Of the techniques evaluated, pro...
