National Institute of Standards and Technology
United States
The National Institute of Standards and Technology in conjunction with the Federal Bureau of Investigation has maintained a database of grayscale fingerprint images, corresponding minutiae and selected latent fingerprints corresponding to fingerprint images in the data set. This data set is known as Special Database 27 (SD-27) and provides 500ppi imagery. In 2010, this data set was expanded to provide 1000ppi imagery to the research community and has been made available for electronic distribution. This data set is herein referred to as SD-27A.
