Biometría Bioseñales y Seguridad

Biometrics Research Lines cover design of bio-metric identification systems (monomode and multimode techniques security evaluation and life subject detection). Stress detection systems by means of physiological signals. Analysis and detection of bio-markers in human scent for medical and bio-metric applications. Public key cipher (elliptical and hipper-elliptical curve, secure protocols for cipher and signature). Cripto-biometry specially based in iris and fingerprint geometry. Computer security. Medical imaging analysis.

Biometrics: This research line covers topics related to iris biometrics (considering not only identification but also template falsification, fake iris images creation),hand geometry oriented to mobile devices, in-air signature based on accelerometers also oriented to mobile devices, gait and face recognition.

In general, our research lines are focused on applying biometrics to mobile devices in order to increase the security in daily applications.


Biosignals: In addition, our interests cover topics related to stress detection in order to improve Human-Computer Interaction (HCI),  providing more security to biometric systems together with the health management in individuals. On the other hand, within this research line we present the biometric technique based on human odour, of great interest in airports, borders and explosive detections.




Security: The research line related to security covers topics oriented to cryptography and their applications. As a result, security rises our interest on cryptobiometrics (the possibility of combining efficiently cryptography and biometrics). Finally, our experience on risk analysis.
