Face
Face biometrics are being used for an increasing number of use cases that pose a range of unique challenges and threats to usability and security.
Face biometric systems and their performance are highly subject to quality issues and potential bias and are the primary subject of presentation attacks using fake biometrics such as masks. Especially in critical contexts, they are often supported by human identity resolvers – who also need training and assessment of performance to ensure good business outcomes.
Face biometrics are used:
In mobile devices, as part of device security mechanisms.
To assess ‘selfie’ images captured by a remote party using cameras in their mobile devices (for instance, for eIDV at digital identity onboarding).
With controlled capture environments in contexts like national border controls.
In semi-controlled capture scenarios such as at the entranceway to a gambling facility.
In uncontrolled capture scenarios such as monitoring CCTV covering a public area.
What Could We Provide?
BixeLab provides a range of testing and analysis services to assess face biometric systems including matching accuracy, quality impacts, bias analysis, and susceptibility to sophisticated presentation attacks. This includes end-to-end investigation and testing of capture, quality and demographic issues, liveness detection and threat scenarios for digital identity systems. Further, BixeLab provides suitability assessments for people who are candidates for manual identity resolution roles, training for these people once selected, and assessment programmes to ensure continuing achievement of high performance.
We can provide you with an understanding of your overall solution’s accuracy, quality, and vulnerabilities – across both your biometric systems, and human identity resolution where appropriate. An understanding of performance provides a basis for significant enhancement through tuning of parameters and thresholds, and management and upskilling of relevant staff.
