Biometrics in a Networked World



Biometrics is generally used within a closed system, for example, an acquisition station may have a single, tethered connection to a biometric sensor requiring the presence of proprietary software. This setup has advantages: (1) it can provide an entire system from a user interface to sensor drivers to the biometric sensor itself; and (2) the user interface may be tailored to the specific device and features that it offers. On the downside, however, interoperability is reduced. If you change the biometric sensor from one model to another, updated software and a new user interface would be required. That is definitely not desirable—having users become familiar with a completely new system costs time and money.

Two new specifications integrating web services into a biometrics system have recently been published: Specification for WS-Biometric Devices (WS-BD), developed by the NIST Biometric Web Services team and published as NIST Special Publication 500-288 [1], and Biometric Identity Assurance Services (BIAS) SOAP (Simple Object Access Protocol – a type of web service) Profile, developed by OASIS BIAS Integration TC.
