Biometric Facial Recognition In Three Dimensions

Biometric Facial Recognition In Three Dimensions

Not just a photo, or an algorithm analyzing a simple X, Y axis, or a PIN number process ... No, not for this Japanese company. What they were really looking for is a system that delivered a sort of "DNA" as in Dynamic Name Association process.

Actual DNA takes way too long but a new type of biometric that goes way beyond simple face recognition seemed to fit the bill.

Face recognition that uses a full three dimensional mapping technique (the first ever of its type) using sub-micron mapping points offered by Bioscrypt, an enterprise access control solution provider, is capable of passive recognition with high performance results in real life environments – typically all that is needed is a glance in the direction of the reader anywhere from 3-6 feet away (video below).

Bioscrypt's facial recognition selected by Japanese agency for access control

Forget ID cards, PINs or 20th century keys, just your face will do. At least that's the premise behind Bioscrypt's VisionAccess 3D Face Reader, which is being deployed by a Japanese government agency. The system will, at sub-second speed, perform multiple facial scans against a database of stored images and corresponding data, granting authorized persons access.

Bioscrypt Inc., a leading provider of enterprise access control solutions, today announced the deployment of its VisionAccess 3D Face Readers at a Japanese Government Agency located in Tokyo. Employees will be identified based on a face match only, without the need for ID cards, keys or PIN technology. In using only biometric identification, the system eliminates the risk of tokens and keys being lost, stolen or misused.

The VisionAccess 3D Face Reader, the world's first three-dimensional facial identification/verification reader with active user feedback, was chosen by the systems integrator, Barrier Reef, as the biometric component of the physical access system to be deployed at the Tokyo based agency because of the unique combination of accuracy and speed of recognition that the system provides.

"The facial recognition units monitor the entry and exit of hundreds of people each day without failure," stated Haruo Kosugi, Director, Barrier Reef. "The agency is extremely pleased with the results and plans on expanding the program to other agencies within the next few months."

"Government agencies around the world continue to rely on Bioscrypt to provide leading edge biometric physical access control technologies to verify the identity of individuals who enter their facilities and with the recent introduction of 3D face solutions, Bioscrypt now offers a greater range of products to meet the demands of partners and end-user prospects," said Robert L. Williams, President and CEO Bioscrypt. "Barrier Reef has proven to be a valued partner for us in the Japanese market and we look forward to continued success with them going forward."

Bioscrypt's advanced 3D facial recognition system uses structured lighting to create a facial grid of 40,000 measurable data points. The system performs multiple facial scans and comparisons against a database of stored images and corresponding data, and conducts accurate identification at sub-second speeds, from which authorized persons are confirmed for access.
