Biometric Data Specification fo

Identity Verification

Changes from January 2005 Draft:

• ANSI/INCITS 378 templates replace A

381 images.

• Addition of verification requirements.• Addition of conformity requirements.• Addition of performance based qualifi• BioAPI has been dropped.
SP 800-76 Template Spec

• Mandatory biometric is now fingerpri• Template specification is the INCITS 

standard.

• 800-76 template specification is an ap

profile of INCITS 378

• 800-76 template specification restricts 

of INCITS 378 :

– No extended data– No proprietary data– Up to three views for each finger.– Restriction of minutia type (bifurcation
Fingerprint Imaging and Re

• Flat fingerprint imaging is specified a

mode of image collection

• The FBI has supported the Type 14 ba

transaction since addition of Appendix Criminal Justice Information Services Fingerprint Transmission Specification 2005.

• Fingerprint images are retained by age• Retention supports regeneration of tem

should amendment of minutiae specifiit necessary.
Facial Data Specificat

• Face specification is INCITS 385 for 

acquisition and storage.

• Face specification is likely not applic

on-card storage. It is more appropriasupport the printed image, and human card issuance and re-issuance.

• Face specification is appropriate for a

face recognition applications where n

• The compression ratio has been relax

suitable for server-side storage.
Common Biometric Exchan

Format (CBEFF) Require

• A CBEFF wrapper is required fo

data on PIV cards.

– Includes mandatory elements.– Includes all agency-optional biome

• A new CBEFF Patron Format w

established.

• The new CBEFF Patron Format 

Patron Format A with:

– Definitive data types for its elemen– Inclusion of the FASC-N, per 800
Verification Requirem

• Sensor meets EFTS/G equiva

specifications. Both enrollmesingle finger sensors will be Fcertified.

• Image output support require

evaluation.

• Threshold calibration require

native PIV Card templates.
Conformance and Guideline 

• Products must have completed MINE

or equivalent to be conformant to SP 

• MINEX report expected on schedule • INCITS M1.3 has a new ad hoc grou

378 minutia angle computation.

• Comment period for December 2005 

Draft has closed. Publication was Fe2006.
800-76 was revised in response to 468 c

from industry and government, from US • Authentication sensor:

– area reduced: min in x-direction 12.8 mm– certification: EFTS Appendix G replaces Appe

• Minutiae Template:

– Add MINEX angle computation.– Maintained <= 128 minutiae.

• Many typos and clarifications.

– Including clarifying figure on notional image f

• NFIQ

– Refined procedure for re-acquiring images on 

measurements of slap segmented images.

• Revamped CBEFF header.

– Flag for encryption is added.– Maintained that all biometric data must be sign
