Smart Sensors Limited, a spin-out from the University of Bath, UK, has
introduced version 2 of its MIRLIN software toolkit, enabling security system
developers to create iris recognition systems capable of 2 million matches per
second, four times faster than other current technologies. Functions include
image acquisition, enrollment, and verification or determination of identity
(ID) from human irises.
Analyzing a digital image of the iris using techniques similar to those employed
in video encoding, the Smart Sensors patented solution requires less processing
power than alternative methods and the software code can operate in only around
300 Kilobytes of memory on a silicon chip. As a result, systems can be based on
small, low-cost microcontrollers with less processing power than an ordinary
personal computer. This makes the technology suitable for use in fixed or
battery-operated, handheld equipment.
Smart Sensors` MIRLIN software development kits (SDK) enable systems to be
optimized for the best combination of speed and accuracy. Images can be scanned
in segments from 18 degrees to 0.72 degrees wide, depending on the accuracy
required. The technology works with iris characteristics that generally conform
to ISO/IEC standards but it is capable of delivering accurate results with
images that are significantly poorer than those defined by the standard.
The SDK can work with a variety of image sources, including several
manufacturers` iris cameras. Versions are available to support various
processors and operating systems. To make licensing more attractive for
customers, the company only charges a fee for each product or each server on a
network, not for every user or enrollment. Customers are supported through
service level agreements that provide bug fixes and product enhancements.
Smart Sensors, which is based in the SETsquared business incubator at the
University of Bath, has recently been awarded the Frost & Sullivan “Global Iris
Biometric Systems Technology Innovation of the Year Award” for 2009.
