Information Technology - Finger Pattern Data Interchange Format



This is the revised version of Finger Pattern Data Interchange Format, ANSI INCITS 377-2004. This standard
specifies an interchange format for the exchange of pattern-based fingerprint recognition data. It describes
the conversion of a raw fingerprint image to a cropped and down-sampled finger pattern followed
by the cellular representation of the finger pattern image to create the finger-pattern interchange data.
The main points of difference between this revised version and the original standard are the inclusion of
two new fields in the Record Header part of the Finger Pattern Data Record. These new fields are called
Capture Equipment Compliance (see and Capture Equipment ID (see The revised standard
also describes a method to store (optional) Core and Delta information in the Extended Data field of
the Finger Pattern Data record (see The above changes were done to improve the standard's
usability from a commercial point of view and also to harmonize it with ANSI INCITS 378-2004, Finger Minutia
Format for Data Interchange.
