Evaluation of Latent Friction Ridge Technology (ELFT) is a series of public tests of one-to-many automated latent friction ridge searching algorithms. Such algorithms are usually part of a larger Automated Biometric Identification System (ABIS). Implementations are provided one or more latent friction ridge images and/or feature sets, and are expected to produce a list of candidates from a large reference database.
Studies of latent friction ridge technology have taken place at the National Institute of Standards and Technology (NIST) since 2006.
There have been several iterations of ELFT over the years. The current version is simply called ELFT. Differentiations of the test will be referred to by changing the version number of the application programming interface (API). Participation in the evaluation is ongoing.
Previous tests with unversioned APIs and time-limited participation were entitled ELFT07 (2006-2007) and ELFT-EFS Evaluations #1 (2008-2011) and #2 (2010-2012).
If you found a bug and can provide steps to reliably reproduce it, or if you have a feature request, please open an issue. Other questions may be addressed to the NIST ELFT team.
The ELFT team sends updates about the ELFT tests to their mailing list. Enter your e-mail address on the mailing list site, or send a blank e-mail to ELFT+subscribe@list.nist.gov to be automatically subscribed.
