Biometrics is an important part of adding multiple factor authentication for identity verification. Traditionally, access control systems have relied on ID cards that can be stolen, lost, shared or copied. With a biometric image associated with a card number there is a secure and efficient way to ensure the person holding a card is the rightful owner.

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.

A4Vision’s 3D facial recognition technology combines high accuracy with minimal user cooperation. The technology utilizes over 40,000 points of data to create a biometric template that is unique to each individual providing for the most precise matching capabilities. The recognition process is performed extremely fast; positive verification of an individual can be accomplished in less then 1 second. The high rates of accuracy and speed characteristics of the A4Vision solution is unprecedented and perfectly suited for fast paced corporate environments.
