BIOMETRICS 2014 – OCTOBER 21st

ADVANCES IN TESTING AND EVALUATION USING HUMAN-BIOMETRIC SENSOR

INTERACTION MODULES

•Examine the advances in Human Biometric Sensor Interaction model

• Current models

• Work ongoing in the Center

TALK TODAY

WHAT IS THE HUMAN BIOMETRIC SENSOR INTERACTION MODEL

•Traditional biometric testing

• Algorithm testing

• Well established metrics

• Well understood testing methodologies

•Operational testing

• Harder to do

• Access to environments

• Test methodologies dependent in some cases on the test

EVALUATION OF BIOMETRIC TESTING

•Training

• How do users get accustomed to devices?

• Can they remember how to use them?

• How do we provide good training to the users that has a consistent message?

GAPS IN BIOMETRIC TESTING

•Accessibility

• How many people know people who have problems with interacting with a biometric systems?

• How do we deal with accessibility and usability issues?

• Hearing and sight issues

GAPS IN BIOMETRIC TESTING

•Human Factors

• Testing and evaluating biometric systems by looking at how the users interact with the system

• Are performance results different in an operational environment than collect in a lab?

• Are these performance results due to the environment?

GAPS IN BIOMETRIC TESTING

• Is the error always subject centric?

• The role of the device?

• The role of the operator?

GAPS IN BIOMETRIC TESTING

TESTING ENVIRONMENTS ARE MORE COMPLEX

BACKGROUND OF THE HBSI MODEL

HBSI MODEL

•Development of the model

• Initially tested the model on iris, fingerprint

• Then introduced the “Dynamic HBSI model” in partnership with University of Kent, Canterbury

• On to more complex systems such as border gates and mobile platforms

HUMAN BIOMETRIC SENSOR INTERACTION

• Challenges are that devices and biometric systems are:

• Now multifaceted

• Variety of form factors, deployments, applications

• In the hands of more customers

• They become more demanding

• Technology development cycle is short

• Opportunity is how to test and evaluate the interactions without it becoming burdensome to a test facility

CHALLENGES / OPPORTUNITIES

•Border gate – the interaction is more than just presenting your biometric

• Heathrow last night….

USE CASE: BORDER GATES

•Token - the passport

•People traveling - potential incorrect passport

•Throughput issues - how to measure

CHALLENGES

•Token

•False Claim

•Attack

NEW ADDITIONS TO THE HSBI MODEL

• HBSI and Border Gates

• Building a border gate in the center to test various technologies, including iris, fingerprint, documents

• Throughput research

• Usability using the Kinect

• Novel performance metrics such as the Stability Score Index

TESTING AND EVALUATION RESEARCH

•Mobile devices are important as well, and we continue to work in this area:

• Wild testing

• Illumination / Noise / Controlled environments

• Voice, face, signature, palm, and multi-factor authentication
