OASIS XML Common Biometric Format (XCBF) - MS13
The OASIS XML Common Biometric Format (XCBF) Technical Committee is defining a common set of secure XML encodings for the patron formats specified in CBEFF, the Common Biometric Exchange File Format (NISTIR 6529). [Note that in later developments, CBEFF has been renamed the Common Biometric Exchange Framework Format] The patron formats are mandatory data elements (vide NISTR 6529) contained in the Standard Biometric Header (SBH) Block of the CBEFF data structure. The intent is to ensure that data contained in the SBH is described using a common XML schema and that it is therefore capable of being read and interpreted in a common fashion between diverse biometric devices and applications.
The Standard CBEFF Data Fields These XML encodings will be based on the ASN.1 schema defined in ANSI X9.84:2003 Biometrics Information Management and Security. They will conform to the XML Encoding Rules (XER) for ASN.1 defined in ITU-T Recommendation X.693, and rely on the security and processing requirements specified in X9.96 XML Cryptographic Message Syntax (XCMS). Current Status The XCBF 1.0 Committee Specification had an initial TC approval and was submitted for public review and comment through February 28, 2003. More comment resolutions were being worked on. The 1.0 CS document was being revised further and became the 1.1 CS document. The 1.1 level is available since June 24, 2003. The CS 1.1 level is already approved by the TC and is approved for submission to OASIS as an open standard. It is currently going through this submission process. About OASIS OASIS is a not-for-profit, global consortium that drives the development, convergence and adoption of e-business standards. Members themselves set the OASIS technical agenda, using a lightweight, open process expressly designed to promote industry consensus and unite disparate efforts. OASIS produces world-wide standards for security, Web services, XML conformance, business transactions, electronic publishing, topic maps and interoperability within and between marketplaces. About CBEFF CBEFF describes a set of data elements necessary to support biometric technologies in a common way. CBEFF features:
About XML The Extensible Markup Language (XML) is a subset of SGML (Standard Generalized Markup Language. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML. In essence, XML permits far greater flexibility than SGML, or HTML in that it permits the individual tag elements to be specified in terms of their content and use (schemas). It is therefore possible to create far more powerful markup elements and to ‘describe’ data elements in a more thorough and flexible manner.
