A new OASIS technical committee is being formed. The OASIS XML
Common Biometric Format Technical Committee (XCBF TC) has been proposed
by the following members of OASIS: Phillip H. Griffin, Griffin
Consulting; John Larmouth, Individual member; Bancroft Scott, OSS
Nokalva; and Paul Thorpe, OSS Nokalva.
The proposal for a new TC meets the requirements of the OASIS TC Process
(see http://oasis-open.org/committees/process.shtml), and is appended to
this message. The proposal, which includes a statement of purpose, list
of deliverables, and proposed schedule, will constitute the TC's
charter. The TC Process allows these items to be clarified (revised) by
the TC members; such clarifications (revisions), as well as submissions
of technology for consideration by the TC and the beginning of technical
discussions, may occur no sooner than the TC's first meeting.
To become a member of this new TC you must 1) be an employee of an OASIS
member organization or an Individual member of OASIS; 2) notify the TC
chair, Phillip H. Griffin (phil.griffin@ASN-1.com), of your intent to
participate at least 15 days prior to the first meeting; and 3)
participate in the first meeting on 18 March 2002. You should also
subscribe to the TC's discussion list. Note that membership in OASIS TCs
is by individual, and not by organization. You must be eligible for
participation at the time you time you notify the chair.
The private mail list xcbf@lists.oasis-open.org is for committee
discussions. TC members as well as any other interested OASIS members
should subscribe to the list by going to the mail list web page at
http://lists.oasis-open.org/ob/adm.pl, or by sending a message to
xcbf-request@lists.oasis-open.org with the word "subscribe" as the body
of the message. (Note that subscribing to the mail list does not make
you a member of the TC; to become a member you must contact the TC chair
as described in the preceeding paragraph.)
A public comment list xcbf-comment@lists.oasis-open.org will be
available for the public to make comments on the work of this TC; the
public may subscribe to this list by going to the mail list web page at
http://lists.oasis-open.org/ob/adm.pl, or by sending a message to
xcbf-comment-request@lists.oasis-open.org with the word "subscribe" as
the body of the message.
The archives of both of these mail lists are visible to the public at

Name of the TC
The name of the technical committee is OASIS TC "XML Common Biometric
Format", usually abbreviated as the XCBF TC.
Statement of purpose
Biometrics are used to prove or help prove identity based on human
characteristics such as DNA, fingerprints, iris scans, hand geometry,
etc. This Technical Committee will define a common set of XML 1.0
encodings for the patron formats defined in CBEFF, the Common Biometric
Exchange File Format (NISTIR 6529, available at
http://www.nist.gov/NISTIR-6529-CBEFF). These formats will be specified
in accordance with the ASN.1 schema definitions published in ANS
X9.84:2000 Biometrics Information Management and Security For The
Financial Services Industry© (available from the ANSI electronic
bookstore at http://www.ansi.org).
Neither of the existing biometric standards, CBEFF and X9.84, provide an
XML schema for securing, displaying, logging or performing database
queries using biometric information. All of the security mechanisms
provided in these standards are based strictly on binary, not XML,
representations of information. There needs to be a standard way for
such tasks to be done using XML; this is the reason for forming the XCBF
TC. Provision of a standard XML schema for biometrics will also serve to
promote interoperability and data exchange among the different patron
formats defined in CBEFF.
The Common Biometric Exchange File Format defines a common set of data
elements necessary to support multiple biometric technologies and to
promote interoperability of biometric-based application programs and
systems by allowing for biometric data exchange. CBEFF describes a set
of "required" and "optional" data fields, a "domain of use", and "CBEFF
Patron" formats that utilize some combination of these standard
elements.
Patron formats specify encoding of the data elements and any additional
(non-common) data elements. The two defined CBEFF Patron formats are
the BioAPI Biometric Identification Record (BIR) format specified in the
BioAPI Consortium BioAPI Specification Version 1.0 and the X9.84:2000
BiometricSyntax type. But all of the encoding formats defined in CBEFF
and X9.84 are binary encodings, making their use in XML systems and
applications limited or difficult.
A common XML schema that can carry the values in all of the CBEFF
standard elements will promote the ability to exchange biometric
information, between users of binary patron formats, and with XML-aware
applications and systems. As new patron formats are added to CBEFF in
future revisions, a common XML schema based on the X9.84 definitions
should make it possible to exchange data with applications implemented
using earlier versions of CBEFF.
Common, underlying type definitions will allow information to be
validated and exchanged without ambiguity. The exact same values
specified in binary encodings will be used in XML representations of
these values. This feature of the work will serve to promote
interoperable solutions.
The canonical variant of the XML Encoding Rules (CXER) will produce
inputs suitable for cryptographic enhancement of the XML representations
of X9.84 biometric objects, but which in that standard are expected to
be processed solely in binary. All processing and security requirements
used by this TC will be harmonized with standardization of the XML
formats of CMS messages undertaken by ANSI X9F working groups.
Proposed list of deliverables and projected dates
* Published document defining the ASN.1/XML CBEFF schema, an
introduction and overview of canonical DER, PER, and XER,
and the processing and security requirements needed for the
creation and verification of all cryptographic types defined
in X9.84, in the form of XML encoded objects
* Published working module including ASN.1 XML Markup Value
Notation examples of X9.84 biometric types defined in the
CBEFF standard, along with the underlying ASN.1 schema
* Published example DER, PER and XER encodings of values of
X9.84 biometric types and equivalent BIR encodings
* Published documentation of new CBEFF patron formats that
may become standard during the period of this work, in
particular an anticipated smart card patron format
* Initial drafts of all deliverables: May 30 2002
* Draft version of working module: November 2002
* Draft version of example binary encodings of XML values:
March 2003
* Draft final versions of all remaining deliverables: May 2003
* Final versions of any new CBEFF formats: July 2003
* Final versions of all deliverables: November 2003
In order to achieve maximum interoperability between the efforts of
various standards organizations, these XCBF deliverables may depend on
work being done by ANSI X9F working groups and the new INCITS M1
Biometrics TC, so the completion of these deliverables may be affected
by delays (if any) in the work of these groups. Though the schedule
extends into November 2003, it is hoped that this work can be concluded
no later than May 2003.
Language in which the TC will conduct business: English. Speakers of
other languages are encouraged to participate.
Date, time, and place of first meeting
18 March 2002, 11 AM EST conference call. (Some participants will be
calling in together from the Hotel Barcelona Universal, Barcelona, Spain
during the UBL TC meeting. Contact the chair to meet this group.)
Proposed meeting schedule for the first year
* Monday March 18, 2002, conference call
* Thursday, May 16, 2002, Somerset, NJ USA.
* Thursday, August 22, 2002, Net Meeting/conference call
* Tuesday, November 19, 2002, Geneva, Switzerland
(just prior to the ITU-T SG17 meeting)
* Further dates for 2003 to be announced
