INCITS 377-2009 [ PDF ] [ Print Edition ]

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 6.2.4.2) and Capture Equipment ID (see 6.2.4.3). 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 6.3.2.2). 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.
