Finger Data Interchange Format, Standardization
Set of ISO Standards that define common formats to encode information related to finger-based biometrics. Those formats are defined to allow interoperability among different vendors worldwide, and have been developed by the international community taking part in ISO/IEC JTC1/SC37 standardization subcommittee. Those documents define not only the way a fingerprint image has to be encoded, but also the way a feature vector composed of minutiae points has to be stored and/or transmitted. Furthermore, formats for the spectral data of the finger, as well as its skeletal data are defined.
Standardization is essential for the wide-spread adoption of technologies in open mass applications. Fingerprint recognition is not only the most prominent biometric measure, but also the biometric trait with the largest databases and the best long-term experience. Fingerprints are used in applications such as...
