Customer will be responsible for their own duties, tax, and VAT. Contact 301 975 2200 or data@nist.gov if you have questions. A sample of the data contained in this database is available via anonymous ftp at sequoyah.ncsl.nist.gov in the files print9.txt and prints9.tar. [13,961]. The NIST database of mated fingerprint card pairs consists of multiple volumes. Currently five volumes have been released. Each volume will be a 3-disk set with each CD-ROM containing 90 mated card pairs of segmented 8-bit gray scale fingerprint images (900 fingerprint image pairs per CD-ROM). Each segmented image is 832 by 768 pixels and classified using the National Crime Information Center (NCIC) classes given by the FBI. The images are compressed using a non-standard implementation of the JPEG lossless compression algorithm. Each CD-ROM requires approximately 630-660 megabytes of storage compressed and 1.0-1.2 gigabytes uncompressed (1.8:1 average compression ratio). The database also includes example software which was written on a SUN 4/470 SPARCserver. The software is the same code used with NIST Special Database 4. NIST Special Database 9 has the following features:
The database is a valuable tool for evaluating fingerprint systems using a statistical sample of fingerprints which approximate a natural horizontal slice of the NCIC classifications.
