NIST Biometric Image Software
The NIST Biometric Image Software (NBIS) distribution is developed by the National Institute of Standards and Technology (NIST) for the Federal Bureau of Investigation (FBI) and Department of Homeland Security (DHS). This software has been determined to be outside the scope of the EAR (see Part 734.3 of the EAR for exact details) as it has been created solely by employees of the U.S. Government; it is freely distributed with no licensing requirements; and it is considered public domain. Therefore, it is permissible to distribute this software as a free download from the internet. It has been determined that the export control restriction did not apply to the NFSEG and BOZORTH3 software, due to both being outside the scope of EAR(see Part 734.3 of the EAR for exact details); they are freely distributed and considered public domain. The NBIS distribution contains C source code for use with biometrics processing and analysis. The NBIS source code is available to download from NIST Biometric Open Source Server. In addition, the NBIS.Net project provides a Microsoft.NET adapter for NBIS, providing an interface to the original NBIS source.
The NBIS utilities fall under eight general categories:
For detail information on NBIS software, please reference to the following documents:
The source code has been developed using the GNU project's gcc compiler and gmake utility (www.gnu.org) , and has been tested under LINUX, Mac OS-X, and under Windows NT using the free Cygwin library and associated tools (www.cygwin.com).
Recommendations on Biometric Quality Summarization across the Application Domain
Quality summarization NISTIR 7422 provides technical guidance for users of biometric quality algorithms in large-scale enterprise operations. Specifically, it recommends the computation and use of performance-related quality summaries, which, for verification, should serve as measures of the overall expected false non-match rate.
How to Contribute to the NBIS Project
The NIST Image Group appreciates all technical contributions to the NBIS project. If you are interested on contributing to the NBIS project, you are welcome to submit your contribution(s) electronically. To contribute, please send an email to firstname.lastname@example.org with the following information: Name, Organization, Contact Information and a brief description of your contribution(s). After we have received your email, we will contact you for further information.
Terms and conditions:
There is no guarantee that your contribution(s) will be included in the NBIS Main development branch; the integration of outside changes is at the sole discretion of the NIST Image Group. However, any changes that are integrated will fall under the same licensing terms as the original software.
Thank you for your interest in using the NBIS software. Unfortunately, we do not have the resources to provide individual support for this software, but do welcome comments for improvement. At the present time we only provide the source code for download.
This software was developed at the National Institute of Standards and Technology (NIST) by employees of the Federal Government in the course of their official duties.
