Technology Advantages
High definition sensing – UPEK high definition sensing captures
the highest quality images for secure authentication and a
convenient user experience.
Capacitive Sensing – UPEK sensors measure feedback
capacitance determined by the presence of 3-dimensional
ridges and valleys of a fingerprint.
Active Pixel Sensing – Each pixel has its own amplifier for
crisp, detailed images.
Live Layer Sensing - UPEK sensors sense both the surface
and the subsurface, or “live layer”, of the skin.
Large Image Area – UPEK sensors scan larger finger areas to enable more accurate authentication and a more accommodating user experience.
Rugged – High sensitivity pixels enable the use of a hard protective coating and the ability to withstand high levels of electrostatic discharge (ESD) for long, trouble-free operation.
Minutiae algorithm – UPEK algorithms extract unique features called “minutiae” from the fingerprint image. Minutia-based matching preserves privacy and minimizes the information that must be stored or transmitted. It is not possible to recreate a fingerprint from the minutia data.
Digital ID Hardware Engine – UPEK’s Digital ID Hardware Engine is a secure processing environment for all biometric operations. Using secure processing protects privacy and insures that biometric results are trustworthy, secure, and accurate. All critical processing is protected from hackers, software viruses and other malware.
Technology Benefits
Security and privacy protection - Reliably recognizes authorized individuals and prevents unauthorized access
Convenience and ease-of-access - Consistently recognizes enrolled users over time and in various environments
Benefits for all - Allows virtually anyone to enjoy the security and convenience benefits of fingerprint authentication
