  1. 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.

  3. 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)

  4. 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:

  5. ANSI/NIST-ITL 1-2000 Type-1 Record

  6. 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 1.001:127GS1.002:0300GS1.003:1US1RS2US00GS1.004:TESTGS1.005:20061101GS1.006:1GS1.007:RECEIVERGS1.008:SENDERGS1.009:TCN001GS1.011:0GS1.012:0FS

  7. ANSI/NIST-ITL 1-2000 Type-2 Record

  8. ANSI/NIST-ITL 1-2000 Type-4 Record

  9. ANSI/NIST-ITL 1-2000 Type-14 Record

  10. 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

  16. EFTS Transactions => BIAS Services
