Fingerprint Biometric System Delivers A Sound Solution

When most people think of a machine that scans ones finger in order to gain entry to documents or a place, they think to themselves “well, this is a little like a page scanner capturing text from a document” … and most solutions feature this type of reflective image capture process.

A new process is beginning to find its way into applications that would greatly improve the development of the fingerprint image captured. The technology applied is “Ultrasound” and this approach has some significant advantages over a standard scan approach.

For example, oily, wet or dirty fingers won't be an issue any more when it comes to capturing accurate fingerprints, according to L-1 Identity Solutions, which announced a partnership to produce a fingerprint scan using high frequency sound waves, the same technology used in the medical profession.

L-1 Identity Solutions and Ultra-Scan develop new live scan device based on ultrasonic imaging

STAMFORD, Conn. -- L-1 Identity Solutions, Inc. announced a partnership with Ultra-Scan Corporation for the development and supply of a revolutionary new live scan biometric fingerprint reader based on ultrasonic imaging technology.

Capturing biometric fingerprint images with high frequency sound waves that are immune to surface conditions extends fingerprint total image accuracy into conditions where it has not been possible before with other scanning technologies. Further, the new device is expected to be significantly smaller and lighter than any solution on the market today. If successful, ultrasonic imaging represents a possible paradigm shift that could supplement or replace optical fingerprint sensors for a number of biometric capture applications.
“Ultra-Scan's fingerprint technology is pushing the science of biometrics to yet another level of performance which will have a broader range of application,” said Robert V. LaPenta, Chairman, President and CEO of L-1 Identity Solutions. “Additionally, utilizing the new, ultrasonic solid state technology developed and patented by Ultra-Scan, these new devices could provide a smaller form factor for mobile and fixed applications, as well as offer a higher level of reliability and ruggedness than presently available.”

Operating much like a photo copier, optical scanners work well for capturing fingerprint images by taking a photo of the fingerprints placed on the glass surface.

Ultra-Scan’s technology, which works similar to medical ultrasound, effectively images through “real-world” contamination found on the finger or built up on the platen surface, to always capture a detailed image of the fingerprints being scanned. This low power device will withstand high degrees of shock and vibration making it ideal for a wide variety of applications.
