Typically, there are three accepted ways to authenticate or prove identity to a system or an authorized person.

  • Something you have – like an ID card.
  • Something you know - such as a PIN number.
  • Something you are - a biometric, such as facial features, fingerprints etc.
When two or more of these are used together for an identification decision it is called multi factor authentication. The PIV program is using, at a minimum, dual factor: card plus biometric, which offers a very secure solution that exceeds using cards alone.

The PIV program typically works in what is called verification mode (1:1) matching. The system verifies that the person belongs to the card by matching the biometric template stored on the card to the person standing in front of the access point and biometric device. A4Vision 3D facial recognition technology can perform this matching process in less than one second for very fast throughput.

Every access situation requires unique consideration. For example, at main entry points where volume throughput capability is critical to maintaining a normal flow of people traffic without interruption, it is imperative to have devices that are both fast and non-intrusive. A4Vision has made many advances in facial recognition technology over the past few years with improvements in critical categories -- security levels/accuracy; speed; and the user experience.

A4Vision facial recognition technology utilizes distinctive features of the face to perform authentication. The 3D Images are captured in real time and focus on features where rigid tissue or bone is most apparent and less likely to change over time, which includes the eye socket curvature, nose, chin, etc. The following are some of the significant advantages that this technology enables.

  • Introduces depth as a 3rd axis of measurement allowing facial angles and curves to be measured on a sub-millimeter scale.
  • Not affected by lighting conditions and may even be used in darkness.
  • Robust to different view angles and has the potential to recognize a subject at near 30 degrees.
  • Ability to perform verification matching in milliseconds.
The points above are very important for system flexibility leading to ease of use for users of the technology. For any biometric technology there are several aspects that are required of the solution for a successful deployment. These factors include a system that requires minimal cooperation from the subject, allows for flexibility in positioning and ambient conditions, has a high level of accuracy, and is ergonomically designed to keep people moving quickly through secured areas.
