HON

HON. The HON file format is a standardized data structure defined within the ISO/IEC 19794 series for the representation and exchange of biometric data. It is specifically designed to encapsulate hand geometry information, which involves the measurements and spatial characteristics of a human hand. This format enables the interoperable storage and transmission of hand-based biometric templates between different systems and devices, supporting applications in identity management and access control.

Overview

The HON format provides a precise framework for encoding hand silhouette and contour data captured by specialized scanning devices. It typically stores a mathematical representation derived from key features such as finger lengths, widths, and joint positions. As part of the broader ISO/IEC 19794 family, which includes standards for fingerprint, iris recognition, and facial recognition data, HON ensures consistency and reliability. This interoperability is crucial for systems deployed by organizations like the International Civil Aviation Organization for travel documents and by national agencies such as the United States Department of Homeland Security. The structured data supports matching algorithms used by vendors like NEC Corporation and Idemia.

History

The development of the HON standard was driven by the growing adoption of biometric authentication technologies in the late 20th and early 21st centuries. Work within Subcommittee 37 of Joint Technical Committee 1 (JTC 1) of the International Organization for Standardization and the International Electrotechnical Commission focused on creating a unified format for hand geometry, a modality pioneered in facilities like Los Alamos National Laboratory. Early commercial systems from companies such as Recognition Systems, Inc. demonstrated the need for standardization to avoid vendor lock-in. The inclusion of HON in ISO/IEC 19794 followed the publication of related standards like ANSI INCITS 398 and was influenced by use cases in high-security environments like Nuclear Regulatory Commission sites and the United States Navy.

Applications

Primary applications of the HON format are found in physical access control systems for secure facilities, including data centers, power plants, and laboratories. It is used for time and attendance tracking in industrial settings by corporations such as Siemens and General Electric. The Federal Bureau of Investigation and Interpol may utilize it in conjunction with other biometrics for forensic investigations. Furthermore, the format supports logical access control in financial institutions like JPMorgan Chase and for single sign-on enterprise solutions. Its use extends to border control systems at airports like Heathrow Airport and Changi Airport, often integrated with e-passport readers compliant with ICAO Document 9303.

Standards and Specifications

The HON format is formally specified in parts of the ISO/IEC 19794 standard, particularly those dealing with hand geometry data. It adheres to common biometric data interchange principles defined in ISO/IEC 19785 for the Common Biometric Exchange Formats Framework (CBEFF). Compliance ensures alignment with broader IT security standards such as ISO/IEC 27001 and frameworks like the National Institute of Standards and Technology's Biometric Data Specification. The specification details record structure, data compression methods, and conformance testing procedures, which are referenced in procurement requirements for agencies like the General Services Administration and the Department of Defense. Related interoperability profiles are also found in the International Association for Biometrics guidelines.
