BitFlow is starting to promote a new fingerprint scanning system based on optical coherence tomography, or OCT.
The system was pioneered by researchers at the Langevin Institute in Paris, and essentially analyzes patterns of interference that arise when light reflects on the rough surface of the finger. By going a step further and comparing images from multiple angles – a system called full-field OCT, or FF-OCT – the researchers believe this system can quickly and accurately map the “internal fingerprint” of a subject.
BitFlow, meanwhile, is helping the work along with its machine vision technology. Its Cyton CXP4 frame grabber is able to collect video and send it to the host computer quickly, all through a single coaxial cable. Commenting on the technology in a press release, one of the lead researchers on the project asserted that the Cyton CXP4’s performance “enabled us to capture images at the camera’s full speed, giving us a distinct competitive advantage on the innovation curve.” In addition to providing this technology, the company is also in a position to promote the system, and in that same statement invited inquiries through corporate channels.
The system is intended to produce fingerprint biometric data that is less susceptible to spoofing, and could become popular if concerns about the security of 2D scanners rise. But with other 3D imaging systems such as those based on ultrasonic technology emerging at the same time, size and cost will become increasingly important, and the FF-OCT system could face some stiff competition in that area.
