ANSI 378, alternatively ANSI/INCITS 378 is a format that stores a description of the minutae (differentiating features) of fingerprints, for production from a fingerprint scan and use by a fingerprint matcher. It is produced by the American National Standards Institute, and the InterNational Committee for Information Technology Standards, giving its name. There are three major versions:
- ANSI 378-2004; "[w]hen people mention ANSI 378 without specifying version, they usually refer to this original 2004 version."[3]
- ANSI 378-2009, similar but incompatible[3]
- ANSI 378-2009/AM1, a slight variation ("AM" is short for "amendment"[4])

Identification
ANSI 378 files will begin with 46 4D 52 00, which is ASCII "FMR" followed by a zero byte[5]. Following this is the version identifier, which is 20 32 30 00 (" 20" followed by a zero byte) for the 2004 version[6], 30 33 30 00 ("030" then zero byte) for the 2009 version[7], and 30 33 35 00 ("035", zero byte) for the 2009/AM1 version[8]. The magic number and format of the 2004 version are the same as for the related but incompatible ISO 19794-2; [9] gives an algorithm to tell them apart.
