(May 2, 2012) New Protocol Enables Wireless and Secure Biometric Acquisition with Web Services
Researchers at the National Institute of Standards and Technology (NIST) have developed and published a new protocol for communicating with biometric sensors over wired and wireless networks—using some of the same technologies that underpin the web.
The new protocol, called WS-Biometric Devices (WS-BD), allows desktops, laptops, tablets and smartphones to access sensors that capture biometric data such as fingerprints, iris images and face images using web services. Web services themselves are not new; for example, video-on-demand services use web services to stream videos to mobile devices and televisions.
The WS-Biometric Devices protocol will greatly simplify setting up and maintaining secure biometric systems for verifying identity because such biometric systems will be easier to assemble with interoperable components compared to current biometrics systems that generally have proprietary device-specific drivers and cables. WS-BD enables interoperability by adding a device-independent web-services layer in the communication protocol between biometric devices and systems.
