Users Guide to Export Controlled Distribution of NIST Biometric Image Software (NBIS-EC)



Kenneth Ko


This report documents the export controlled distribution of biometric image software (NBIS-EC). The NBIS-EC software is organized into two major packages: 1. NFSEG is a fingerprint segmentation system useful for segmenting four-finger plain impressions, 2. BOZORTH3 is a minutiae based fingerprint matching system. It is our understanding that this software falls within ECCN 3D980, which covers software associated with the development, production or use of certain equipment controlled in accordance with U.S. concerns about crime control practices in specific countries. This documentation provided the overview of the export controlled distribution of NBIS software, software installation guide, some algorithmic overview of the NBIS export controlled software and Reference Manual describing each program in this distribution.
