International Workshop on Usability and Biometrics: NIST Welcome

1. International Workshop on Usability and Biometrics:NIST Welcome Martin Herman, Ph.D. Chief, Information Access Division

2. Purpose of Workshop – identify gaps and opportunities for further research and standards in biometric usability • NIST’s Information Access Division is a co-host

3. Usability and Biometrics • NIST IAD has a history of biometrics research going back decades • NIST IAD has a history of usability research since the mid 1990’s • Recognized that usability could enhance performance of biometric systems (e.g., system throughput; biometric sample quality)

4. NIST biometrics work focuses on • Needs of industry, government, and academia in R&D for enhancing biometric technologies • Needs from USA Patriot Act and Enhanced Border Security and Visa Entry Reform Act • NIST works very closely with DHS and supports US-VISIT (entry/exit system for foreign visitors) • Needs for law enforcement & Intelligence Community • NIST works very closely with the FBI • Integrated Automated Fingerprint Identification System (IAFIS) – largest biometrics database in the world; Next Generation Identification (NGI) • NIST works closely with National Institute of Justice on DNA • NIST works closely with the R&D components of the Intelligence Community • Needs for Homeland Security Presidential Directive-12 • Personal Identity Verification (PIV) ID card for federal employees and contractors • Needs defined by White House National Science & Technology Council (NSTC) Subcommittee on Biometrics and Identity Management • “National Biometrics Challenge”

5. What NIST does in biometrics • Standards Development • Work with others to accelerate the development of consensus-based standards which are closely coupled to the stated needs of private industry • Development of test and evaluation methods • Develop metrics, testing design, evaluation methodology, performance & conformance testing, data collection and formatting • Perform tests and evaluations • On both research systems and vendor products • Develop and transfer technology

6. NIST biometrics modalities • Fingerprints (Includes Latent Fingerprints) • Face • Iris • Voice • DNA • Multimodal

7. NIST biometric standards activities • NIST Standards • ANSI/NIST ITL 1-2007 - Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information – used in law enforcement and interagency biometric data exchange • NIST Special Publication 800-76-1 -- Biometric Specification for Personal Identity Verification – as part of FIPS for PIV cards • American National Standards • International Committee for Information Technology Standards (INCITS) • International Standards • International Organization for Standardization/International Electrotechnical Commission (ISO/IEC)

8. Finger Projects • [ELFT] Evaluation of Latent Fingerprint Technologies • Evaluate and advance latent fingerprint matching technologies • Fast Fingerprint Capture Evaluation • Develop methods and standards for evaluating next generation fingerprint acquisition systems; e.g. contactless and 3D • [MINEX] Minutia Exchange Tests • MINEX04 -- Interoperability of INCITS 378 fingerprint template • Ongoing MINEX -- Supports compliance for Personal Identity Verification (PIV) program • MINEXII -- Fingerprint template interoperability with Match-on-Card technologies • [PFT] Proprietary Fingerprint Template Testing • SDK fingerprint matcher tests • [SlapSeg] Slap Segmentation Tests • Evaluate the performance of slap fingerprint segmentors

9. Face Projects • [FRVG] Face Recognition Grand Challenge • Advance state of the possible with face recognition • [FRVT] Face Recognition Vendor Tests • Evaluate state of the possible with face recognition • Evaluation of Face for US-VISIT

10. Iris Projects • [ICE] Iris Challenge Evaluation • Evaluate the accuracy of iris matching technologies • [IREX08] Iris Exchange Test • Study and compare accuracy and interoperability as related to iris compression levels and alternative image formats • Evaluation of Iris for US-VISIT

11. Voice Projects • Speaker Recognition Tests • Evaluation of speaker identification technologies • Voice Biometrics • Develop methods for standardized voice enrollment followed later by 1-to-many speaker identification

12. DNA Projects • Develop standards and methods for processing and matching DNA

13. Multiple Biometrics • Large-Scale USG Systems (e.g. FBI IAFIS/NGI & DHS US-VISIT) • Conduct benchmarking & performance evaluations • Develop and evaluate next generation biometric capabilities & integration of standards • Evaluate system interoperability • [MBARK] Multimodal Biometric Application Resource Kit • Develop client-side technologies and standards for multimodal biometric acquisition • [MBGC] Multiple Biometric Grand Challenge • Evaluate performance with multimodal use of face and iris • Quality • Develop standards and methods for evaluating and utilizing biometric sample quality

14. Recent NIST IAD usability research • Usability engineering • Industry Usability Reporting (IUSR) Project • Goal: Develop family of usability standards to support reporting on the usability lifecycle process. This includes requirements, formative, and summative testing • Common Industry Format (CIF) for Usability: Approved by ISO SC7-SC4: Software Product Quality Requirements and Evaluation (SQuaRE) - Common Industry Format (CIF) for Usability – General Framework for Usability-related Information • Interactive Intelligent Systems • Today’s computing power resides with end users (as opposed to central computing facilities). Novel interfaces (e.g. virtual environments and wearable devices) and novel interactions (e.g. haptic devices, touch screens, speech) require novel evaluation methods and new metrics for measuring system effectiveness • Evaluation includes principles of usability (efficiency, effectiveness, user satisfaction), but also whether novel technologies actually provide utility to the end user. • Applied interactive system utility measurements against some hard problems in both the intelligence community (IC) and the military (DARPA). • Usability and Accessibility for Voting Systems • Today’s voting systems have poor usability and accessibility. NIST was called upon in the HAVA Act to provide technical assistance to develop standards and test methods to improve voting system usability and accessibility.
