Mobile Biometric Data Transmission


Mobile Identification
The ANSI/NIST-ITL standard has formed the basis for transmission of biometric data in law enforcement related applications throughout the world. In July 2009, NIST published the Mobile ID Device Best Practice Recommendation, Version as Special Publication 500-280, commonly referred to as the Mobile ID BPR. It included many specifications that were eventually incorporated into the 2011 version of the ANSI/NIST-ITL standard Data Format for the Interchange of Fingerprint, Facial Other Biometric Information, NIST Special Publication 500-290. Since the publication of the Mobile ID BPR, several companies have marketed products with claims of conformance to its specifications.

A major change influenced by the Mobile ID BPR was the addition of Subject Acquisition Profile (SAP) levels for facial acquisition from mobile devices. Subject Acquisition Profiles for Fingerprint (FAP) and Iris (IAP) were also added to the standard based upon the Mobile ID BPR.

However, the Security and Encryption, Communication Protocols, and Profiles (Military and Law Enforcement) were not incorporated into ANSI/NIST-ITL 1-2011.

The addition of new modalities to the ANSI/NIST-ITL 1-2011 standard that can be acquired in a mobile environment (such as DNA and voice), as well as practical experience gained in applying the concepts of the Mobile ID BPR led to requests to update the document, and incorporate it as part of the standard itself. A major area that was asked to be considered was the development of a 'lite' version of the transmission standard for mobile use. This has been specifically addressed in this Supplement.

This Supplement does not re-specify the elements of the Mobile ID BPR that were incorporated into ANSI/NIST-ITL 1-2011. It is possible and in many cases highly desirable to use a full ANSI/NIST-ITL transmission format, even when acquiring data in a mobile environment. However, some circumstances may dictate smaller communication packages, or Standard operating procedures (SOPs) may dictate that the person collecting the biometric data in the mobile environment do a minimum of, or no data entry 'on location,” with data entry performed at another location. This data entry could even be based directly upon voice capture of spoken information from the operator at the time of biometric sample collection.

Part of this document is normative and some is informative. They are clearly marked. To highlight the practical aspects of deploying mobile ID devices, there is a section in this document discussing several 'real life' examples.
