ANSI/NIST-ITL 1-2000/6 and EFTS

• Overview and Relationship to BIAS

2
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.

ANSI/NIST-ITL 1-2000

• 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
• Low/High resolution grayscale fingerprint image
  (Type-3/4)
• Low/High resolution binary fingerprint image
  (Type-5/6)
• User-defined image (Type-7)
• Fingerprint minutiae (Type-9)
• Variable resolution latent image (Type-13)
• Variable resolution tenprint image (Type-14)
• Variable resolution palm print image (Type-15)
• Signature images (Type-8)
• Facial images (Type-10)
• SMT images and descriptive details (Type-10)

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

ANSI/NIST-ITL 1-2000 Type-1 Example

• The following example shows a Type-1 tagged-field
  logical record, which describes a TEST
  transaction from SENDER to RECEIVER with a
  transaction control number of TCN001 sent on
  November 1, 2006

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

11
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

12
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

13
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

14
EFTS Example Type-2 Fields
15
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
