ANSI/NIST-ITL 1-2000/6 and EFTS
Overview and Relationship to BIAS
Introduction

ANSI/NIST-ITL 1-2000: Data Format for the Interchange of
Fingerprint, Facial, & Scar Mark & Tattoo (SMT) Information


An approved ANSI standard for describing the fingerprint data
interchange format used by Law Enforcement agencies (e.g., FBI,
State and Local Police)
Currently being updated with a number of changes, including an
XML representation.


This update, commonly referred to as ANSI/NIST-ITL 1-2006, has not yet
been approved. A proposed draft is currently in review.
EFTS: Electronic Fingerprint Transmission Specification


A specific implementation of the ANSI/NIST-ITL 1-2000 standard,
describing how to communicate with the FBI IAFIS.
Will be updated to reflect changes in ANSI/NIST-ITL 1-2006 and
renamed to EBTS: Electronic Biometric Transmission Specification.

Defines 16 record types for exchanging various pieces of
information (Logical Records):



Transaction itself (Type-1)
Demographic/Rap sheet (Type-2)
Fingerprint and Palm Print images and fingerprint minutiae

ANSI/NIST-ITL 1-2000



A transaction file is composed of one or more logical records
The logical records utilize either tagged fields or fixed-length binary
fields
Logical records and information in the tagged-field records are delimited
by separator characters:
ASCII Character
Description
FS
Separates logical records of a file or is the terminating
character of a transaction.
GS
Separates fields of a logical record
RS
Separates multiple data entries (subfields) of an information
field
US
Separates individual information items of the field or subfield

ANSI/NIST-ITL 1-2006 Changes

Includes an XML representation of the standard








Base-64 encoding of binary image data
Global Justice XML Data Model (GJXDM) objects used when
available
Adds a logical record for iris images (Type-17)
Adds a logical record for other biometrics [CBEFF-encoded]
(Type-99)
Harmonizes minutiae record (Type-9) with INCITS 378
Substantially changes the facial record (Type-10)
Provides specifications for “identification flat” data (Type-14)
Adds image quality information to various logical records

ANSI/NIST-ITL 1-2006 Timeline




Proposed draft recently posted at
http://fingerprint.nist.gov/standard
Comments are due by November 27, 2006
Updated draft will be canvassed (balloted) in December
Assuming approval, draft will be submitted to ANSI for
finalization in 1Q 2007

Will probably be called ANSI/NIST-ITL 1-2007

ANSI/NIST-ITL Relationship to BIAS

Although in a different format, ANSI/NIST-ITL 1-2000/6
transaction files could be translated to BIAS services


ANSI/NIST-ITL 1-2000/6 does not describe any specific transaction
types, so specific mappings cannot be provided
ANSI/NIST-ITL 1-2000/6 biometric data representations can
be mapped to the proposed BIAS biometric data
representation, which uses CBEFF


Format types for ANSI/NIST-ITL 1-2000 records have been defined
(Reference: INCITS M1 Standing Document SD2,
http://www.incits.org/tc_home/m1htm/2006docs/m1060018.htm)
The ANSI/NIST-ITL Type-99 record specifies a CBEFF patron format
11
EFTS

Defines the transactions and their required logical
records/fields for communicating with the FBI IAFIS


Extends/customizes/implements the ANSI/NIST-ITL 1-2000 standard
Example: Criminal Ten-Print Submission (Answer Required)




Type of Transaction: CAR
Logical Record Requirements: one Type-1, one Type-2, zero to four
Type-10, and fourteen Type-4
Defines Type-2 fields for use with EFTS transactions
(examples follow on next slide)
Sets other requirements/specifications, such as:


Minimum image quality specifications
Allowed image compression techniques

EFTS Relationship to BIAS



EFTS transaction types can be mapped to BIAS services
(see following slide)
EFTS Type-2 records (demographic data) can be utilized in
the BIAS biographic representation as-is
No differences from ANSI/NIST-ITL 1-2000/6 for the
biometric data mapping
