New computer technology can identify partial, smudged or 'warped' fingerprints in seconds
New computer technology can identify partial, smudged or 'warped' fingerprints in seconds.
Worn and ravaged hands have for a long time been a stumbling block for fingerprint access control readers. NPL has recently verified new computer technology developed by the University of Warwick that can identify partial, smudged or 'warped' fingerprints in seconds.
The technology developed by the University of Warwick and verified by NPL is able to identify partial, distorted, scratched, smudged, or otherwise warped fingerprints in just a few seconds. This technology has been taken forward by University of Warwick spin out company, Warwick Warp, and it has recently been deployed for security and staff management on six building sites.
This biometrics system works reliably with poor quality fingerprints, the type routinely seen in the construction industry, as it is fast, accurate and eliminates the 'buddy punching' problems of older card-based access systems.
Warwick Warp's fingerprint technology gave the best overall accuracy in NPL's benchmark tests, and a test of 36 fingerprint technologies by the National Institute of Standards and Technology (NIST) in the US ranked it third overall.
