BWS IconBiometric Web Services

Combining biometrics and web services to enable multimodal biometric interoperability and enhance mobile identification and remote authentication.

N E W S

  • The OASIS Biometrics TC has opened a ballot to approve WS-Biometric Devices v1.0 Committee Specification Draft 03 as a Committee Specification.
  • NIST is seeking potential collaborators for a Statement of Use that would help progress the OASIS WS-Biometric Devices v1.0 to an OASIS standard. Specifically, we seek a partner that could work with NIST in testing the interoperability of WS-Biometric Devices services. Please contact us for more information.

Overview

"Web services" is a general term given to machine-to-machine communication using the same protocols that underlie the web. Our computers, cellular phone, set-top boxes (i.e., digital video recorders, cable boxes)—even our alarm clocks—all natively understand these common protocols. By using Web services as a means for interoperability, the capabilities and reach of biometrics is significantly improved.

Web services make it easier to allow

  • Wireless communication over commonly available equipment; for example the same sorts of wireless routers commonly found in homes today.
  • Worldwide connectivity. Any device that can visit a Web page can use the same underlying protocols to communicate with a biometric sensor; no platform-specific middleware (software) is necessary.
  • Secure communications biometric capabilities via widely implemented security protocols such as TLS (formerly known as SSL).
 

 Camera Web Services for Biometric Devices (WS-Biometric Devices)

WS-Biometric Devices, or WS-BD, is a new command & control protocol for biometric devices. It uses the language for the web; proprietary knowledge of sensor interfaces are no longer required. Desktop, laptop, tablet, and smartphone applications can access sensors just as easily as they can navigate to a website.

Specification

The WS-Biometric Devices specification has been published as NIST Special Publication 500-288.

NIST continually welcomes feedback, comments, and questions on the specification for consideration during updates. Send your comments directly to the WS-Biometric Devices team by emailing 500-288comments@nist.gov.

Reference Implementations

NIST has written two reference implementations against the WS-Biometric Devices specification. To help ensure the quality of the specification, they were developed independently on two different platforms. See the included README files for more information.

ZIP icon.NET Reference Implementation (06 September 2013) (ZIP, 899 KB)

ZIP iconJava Reference Implementation (v1.1.28) (ZIP, 393 KB)

The .NET reference implementation has been written in Visual Basic .NET, but is accessible from any .NET programming language. Both implementations include comprehensive integration tests that demonstrate how to use the specification and the implementation.

Reference Application

NIST has authored a reference application that showcases the WS-Biometric Devices (WS-BD) specification. The wsabi application (web services for acquiring biometric information) is a touchscreen-based app for collecting biometric data from WS-Biometric Device -capable sensors.

The (iOS / Objective-C) source code for wsabi is located at the project's GitHub repository:

The user interface for wsabi was generated through a series of formal usability tests. NIST IR 8003, Design and Testing of a Mobile Touchscreen Interface for Multi-Modal Biometric Capture documents the user testing resulting recommendations for general purpose biometric capture with touch & gesture.

 BIAS Biometric Identity Assurance Services

BIAS defines a framework to deploy and invoke biometric operations, such as enrolling, identifying (comparing one to many), and verifying (comparing one to one) biometric information over a service-oriented architecture. It is a high-level abstraction that supports any biometric modality or data format.

OASIS Standard

The OASIS BIAS TC has developed a Simple Object Access Protocol (SOAP) Profile aligning to INCITS 442:2010 – Biometric Identity Assurance Services (BIAS).

The OASIS BIAS SOAP Profile became an official OASIS standard on 24 May 2012. The OASIS Biometrics TC continues to maintain the BIAS standard.

Reference Implementation

NIST developed a reference implementation to complement the 24 May 2012 standard. There are two components: a service and a client. The service is written in Visual Basic.Net and the client in Adobe Flex. It is a functional service which matches fingerprints using the Bozorth3 algorithm from NBIS.Net.

 Wrench_Double NIST Biometric Image Software for .NET (NBIS.NET)

The NIST Biometric Image Software (NBIS) distribution contains C source code for use in biometrics processing and analysis. NBIS.NET is an interoperability layer that provides a direct in-process interface to the native NBIS libraries directly from .NET.

ZIP iconDownload NBIS.Net for NBIS 4.2.0 (31 October 2013) (ZIP 4,386 KB)

The 31 October 2013 version has been updated to support NBIS 4.2.0. NBIS.NET only support 32-bit (Intel x86) architectures. Please contact us if you are interested in collaborating on (Intel/AMD) 64-bit support.
