Abstract
This document provides instructions for latent print examiners in marking friction ridge features to maximize consistency among examiners. This document builds upon the Extended Feature Set (EFS) defined in American National Standard for Information Systems: Data Format for the Interchange of Fingerprint, Facial & Other Biometric Information, American National Standards Institute/National Institute of Standards and Technology, Information Technology Laboratory (ANSI/NIST-ITL) 1-2011. These instructions include examples and specific guidance for latent print examiners and minimize references to technical details of the file format.
Three interrelated specifications have been designed to enable vendor-neutral latent automated friction ridge identification systems (AFIS) interoperability: the EFS Profile Specification; the Latent Interoperability Transmission Specification; and this one, the Markup Instructions for Extended Friction Ridge Features. The three documents define data exchange specifications for latent print interoperability and are all based on the EFS features in the ANSI/NIST-ITL (2011) standard.
