  • We strive to achieve our mission through a partnership between industry and academia, bridging cultures to find solutions to the challenges associated with developing and implementing biometric technologies.
  • Education Over 10 years of experience in education: undergraduate, graduate, distance, and industrial settings. Developed several courses on the application of biometric technologies. Research Apply our research skills to real-world needs and study all aspects of the biometric system. Research focuses on solving issues that are observed in the field. Wide and varied research agenda Performance analysis, Identity management, Usability and user perception of biometric systems. Standards Active with ISO JTC1 SC37 and INCITS M1 biometrics committee. Testing Services The BSPA Lab offers applied research and evaluation services aimed at industry and government to overcome hurdles in operation and selection of biometric systems.
  • Survivability of the bacteria on the device was determined by contaminating each device with a known concentration of bacteria and recovering organisms over a period of time Transferability of bacteria over time from biometric devices was investigated by intentionally contaminating the device surface with one species of bacteria at a time and touching the surface 50 times
  • Health information exchange Commitment techniques and zero-knowledge proofs
  • Consider the scenario in which a clinic and a lab each have a trust relationship with a hospital; however, they do not have a direct trust relation with each other. A physician has a joint appointment at both the clinic and the hospital and can have different identities in both institutions. The scenario takes into account a number of important requirements for different classes of users (doctors, patients), and also requirements of the healthcare providers
