Fujitsu Microelectronics America Inc. and 123ID Inc. has introduced new development kits that can enable developers to quickly incorporate fingerprint authentication into Windows-based applications used in network authentication, secure fingerprint ID login, password replacement, file encryption, access control, POS and commercial and government identity-management systems.

The new DKF-UMS Software Developer Kits (DKF-UMS-1120, 1130, 1117 and 1137) incorporate an vector/minutia-based fingerprint authentication algorithm with fingerprint-image-capture software. Built around the Fujitsu MBF200 single touch sensor, which provides 8bit 500dpi forensic quality images, the DFK-UMS supports Windows 2000, XP and Vista systems and provides extensive sensor-calibration routines to accurately image wet, dry or damaged fingers. The different Developer Kits offer open and standard licensing in 1-1 (Verification) and 1-N (Identity) management configurations.

The Fujitsu and 123ID technology provides 32bit dynamic and static libraries, along with reference design documentation for interfacing the MBF200 to the USB 1.1 system and embedded systems. A matching engine can interoperate between the MBF200 sensor and compliant INCITS-378 (M1) templates generated from other fingerprint sensor manufacturers and matching engine providers. The vector/minutia-based fingerprint algorithm outputs 1-Many INCITS-378 NIST-compliant templates and embedded 1-1 FIPS-201 NIST-compliant templates. An executable version of a sample application demonstrates the enrollment, verification and identity management captured with the supplied MBF200 USB module. Sample source code and complete sample project application files for Visual C++, Visual C#, Visual Basic and HTML are included.

Easy biometric security design
"Fingerprint sensor technology is delivering unprecedented levels of security in various platforms and applications," said Philip Hopkins, biometrics product manager, embedded systems business group, FMA. "Our new software kits simplify development of biometric solutions that can complement or replace passwords, tokens and other security systems."

According to Roger Quint, CEO of 123ID, they offer interoperability between different fingerprint scanners in large, interconnected and integrated IT systems as well as the capability of a one-to-many matching solution.

Software modules in the kit include the Capture, Verify, Identify and Minutiae Extraction Modules. The Capture Module calibrates the Fujitsu fingerprint sensor and automatically adjusts the sensor sensitivity to create the optimal image, providing a raw fingerprint image and fingerprint template. The Verify and Identify Modules, which are available in DLL, static libraries and ActiveX form, perform interoperable matching with fingerprints captured on the MBF200 USB touch sensor. The Minutia Extraction Module finds the endings of the ridges and bifurcations in a fingerprint and generates minutia compatible with FIPS-201 NIST specifications. This module also enables batch and massive creation of fingerprint templates for volume testing under 1-Many and Identify conditions.

DKF-UMS is compatible with FIPS 201 and the Fujitsu architecture carries 378 native templates delivered by the 123ID biometric technology. The kit includes a CD with all files, object code, documentation, shield application data, sample code and project files, along with the MBF200 hardware, reference schematic and matching engine libraries in DLL and ActiveX form. The kit is available in single or open license with prices starting at $3,000.
