Information technology — Biometric data interchange formats — Part 6: Iris image data

ISO/IEC 19794-6:2005 specifies two alternative image interchange formats for biometric authentication systems that utilize iris recognition. The first is based on a rectilinear image storage format that may be a raw, uncompressed array of intensity values or a compressed format such as that specified by ISO/IEC 15444. The second format is based on a polar image specification that requires certain pre-processing and image segmentation steps, but produces a much more compact data structure that contains only iris information. Data that comply with either one of the iris image formats specified in ISO/IEC 19794-6:2005 are intended to be embedded in a CBEFF-compliant structure in the CBEFF Biometric Data Block (BDB) as specified in ISO/IEC 19785-1.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
ISO/IEC 19794-6 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 37, Biometrics.
ISO/IEC 19794 consists of the following parts, under the general title Information technology — Biometric data
interchange formats:
 Part 1: Framework
 Part 2: Finger minutiae data
 Part 3: Finger pattern spectral data
 Part 4: Finger image data

Introduction
The purpose of this document is to define a standard for exchange of iris image information. This part of
ISO/IEC 19794 contains a specific definition of attributes, a data record format for storing and transmitting the
iris image and certain attributes, a sample record, and conformance criteria.
Currently, exchange of iris information between equipment from different vendors can only be done using a
large-scale image of the entire eye. This is expensive in storage and bandwidth. To provide interoperability
among vendors, it is necessary to define a standard, compact representation of a human iris.
The biometric data record specified in this part of ISO/IEC 19794 shall be embedded in a CBEFF-compliant
structure in the CBEFF Biometric Data Block (BDB).
The International Organization for Standardization (ISO) and the International Electrotechnical Commission
(IEC) draw attention to the fact that it is claimed that compliance with this document may involve the use of
patents concerning iris recognition given in Clause 6 and/or Annex A.
The ISO and IEC take no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the ISO and IEC that he/she is willing to negotiate licenses
under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this
respect, the statement of the holder of this patent right is registered with ISO and IEC. Information may be
obtained from:
Iridian, Technologies, Inc.
Mr. Robert Levin Corporate Counsel
1245 N. Church Street
Moorestown, NJ 08057 USA
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights other than those identified above. ISO and IEC shall not be held responsible for identifying any or all
such patent rights.

Part 6:
Iris image data
1 Scope
This part of ISO/IEC 19794 specifies two alternative image interchange formats for biometric authentication
systems that utilize iris recognition.
The first is based on a rectilinear image storage format that may be a raw, uncompressed array of intensity values
or a compressed format such as that specified by ISO/IEC 15444.
The second format is based on a polar image specification that requires certain pre-processing and image
segmentation steps, but produces a much more compact data structure that contains only iris information.
Data that comply with either one of the iris image formats specified in this part of ISO/IEC 19794 are
intended to be embedded in a CBEFF-compliant structure in the CBEFF Biometric Data Block (BDB) as specified
in ISO/IEC 19785-1.
2 Conformance
Conformity with this part of ISO/IEC 19794 requires compliance with one of the data formats described in
clause 6.  Recommended image quality criteria described in Annex A are expressed in terms of resolution,
contrast, noise level, etc. Because iris recognition applications may have varying image quality requirements,
four different levels of image quality are defined in Annex A. In general, the highest image quality level is
recommended for high-volume, high-security applications where the lowest possible recognition error rates
are required. Lower levels of image quality are appropriate for less demanding applications in which higher
error rates can be tolerated but camera cost is a critical factor.

Information technology — Cross-jurisdictional and societal aspects of implementation of biometric technologies — Pictograms, icons and symbols for use with biometric systems — Part 5: Face applications

The ISO/IEC 24779 series of standards focuses on communication with the data capture subject. This document contains a set of pictograms, icons and symbols to help the general public understand the concepts and procedures for using electronic systems that collect and/or evaluate facial images. Operators can use this document, with the possibility of using additional symbols and information. This set of pictograms, icons and symbols is designed to be used to: — identify the type of biometric sensor; — provide supporting instructions related to facial image collection. To provide this functionality, the set of pictograms, icons and symbols includes both directional pictograms, icons and symbols and action or feedback pictograms, icons and symbols. The facial image pictograms, icons and symbols include: — facial image capture; — single person; — no hat; — no sunglasses; — neutral expression; — hair up; — view direction. Although the pictograms, icons and symbols are presented individually, the pictograms, icons and symbols are intended to be combined to fully illustrate the facial image capture interaction. For example, in a customs or immigration environment, procedures constructed from the individual pictograms, icons and symbols could be presented as: — a series of posters while passengers are in the queue; — a series of transitional frames in a biometric booth; — an animated video or series of transitional frames while passengers are in the queue; — instructional leaflets for passengers to read in the queue.

Information technology — Guidelines for slap tenprint fingerprintture

This document provides guidelines to follow during the acquisition process of slap tenprints in order to obtain fingerprints of the best quality possible within acceptable time constraints. Non-cooperative users are out of the scope of this document. When using ten-fingerprint sensors, it is fundamental to know how to use them and how to proceed with the acquisition. This document describes how to capture fingerprints correctly by specifying best practices for slap tenprint captures. It gives recommendations on the following topics: 1) hardware of the fingerprint sensor and its deployment; 2) user guidance; 3) enrolment process including a sample workflow; 4) application software for developers and system integrators; 5) processing, compression and coding of the acquired fingerprint images; 6) operational issues and data logging; 7) evaluation of a solution and its components. Although this document primarily focuses on reaching optimal data quality for enrolment purposes, the recommendations given here are applicable for other purposes. All processes which rely on good quality tenprint slaps can take advantage of the best practices.

Information technology — Guidance for biometric enrolment

This document consolidates information relating to successful, secure and usable implementation of biometric enrolment processes, while indicating risk factors that organisations proposing to use biometric technologies will should address during procurement, design, deployment and operation. Much of the information is generic to many types of application, e.g. from national scale commercial and government applications, to closed systems for in-house operations, and to consumer applications. However, the intended application and its purpose often have influence on the necessary enrolment data quality and are intended to be taken into account when specifying an enrolment system and process. The document points out the differences in operation relating to specific types of application, e.g. where self-enrolment is more appropriate than attended operation. This document focuses on mandatory, attended enrolment at fixed locations. In summary, this document consolidates information relating to better practice implementation of biometric enrolment capability in various business contexts including considerations of process, function (system), and technology, as well as legal/privacy and policy aspects. The document provides guidance on collection and storage of biometric enrolment data and the impact on dependent processes of verification and identification. This document does not include material specific to forensic and law enforcement applications. This document does not contain any mandatory requirements. The following terms are used in this document to provide guidance. The terms "should" and "should not" indicate that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is discouraged but not prohibited. The term "may" indicates a course of action permissible within the limits of the publication. The terms "can" and "cannot" indicate a possibility and capability, whether material, physical or causal.

ISO/IEC 19784-1:2018(Main)
Information technology — Biometric application programming interface — Part 1: BioAPI specification

ISO/IEC 19784-1:2018 defines the Application Programming Interface (API) and Service Provider Interface (SPI) for standard interfaces within a biometric system that support the provision of that biometric system using components from multiple vendors. It provides interworking between such components through adherence to this and to other International Standards. For use in a system that does not include a BioAPI Framework (called a framework-free BioAPI system), only the SPI interface is applicable, with applications interfacing directly to that in a platform-specific manner. NOTE 1 Many clauses and/or sub-clauses of this document are not applicable for implementation of a framework-free BioAPI system. These are identified at the head of the clause of sub-clause. The BioAPI specification is applicable to a broad range of biometric technology types. It is also applicable to a wide variety of biometrically enabled applications, from personal devices, through network security applications, to large complex identification systems. ISO/IEC 19784-1:2018 supports an architecture in which a BioAPI Framework supports multiple simultaneous biometric applications (provided by different vendors), using multiple dynamically installed and loaded (or unloaded) Biometric Service Provider (BSP) components and BioAPI Units (provided by other different vendors), possibly using one of an alternative set of BioAPI Function Provider (BFP) components (provided by other vendors) or by direct management of BioAPI Units. NOTE 2 Where BioAPI Units are provided by a different vendor fom a BSP, a standardised BioAPI Function Provider Interface (FPI) may be needed. This is outside the scope of this document, but is specified by later parts for the different categories of FPI. NOTE 3 Where a BioAPI Framework is not used in a system, the ability to support multiple applications and multiple BSPs is platform-dependent and depends on the nature of the system-integration techniques employed. ISO/IEC 19784-1:2018 is not required (and should normally not be referenced) when a complete biometric system is being procured from a single vendor, particularly if the addition or interchange of biometric hardware, services, or applications is not a feature of that biometric system. (Such systems are sometimes referred to as "embedded systems".) Standardisation of such systems is not in the scope of this document. ISO/IEC 19784-1:2018 does not define security requirements for biometric applications and biometric service providers. NOTE 4 ISO 19092 provides guidelines on security aspects of biometric systems[3]. The performance of biometric systems (particularly in relation to searches of a large population to provide the biometric identification capability) is not in the scope of this document. Trade-offs between interoperability and performance are not in the scope of this document. ISO/IEC 19784-1:2018 specifies a version of the BioAPI specification that is defined to have a version number described as Major 2, Minor 0, or version 2.0. It also specifies a version number described as Major 2, Minor 1, or version 2.1 that provides an enhanced Graphical User Interface. It also specifies a version number described as Major 2, Minor 2, or version 2.2 that provides features supporting fusion and security. Some clauses and sub-clauses apply only to one of these versions, some to two or more. This is identified at the head of the relevant clauses and sub-clauses. NOTE 5 Earlier versions of the BioAPI specification were not International Standards. NOTE 6 The differences between the requirements of the 2.0 specification and the 2.1 specification for framework-free operation relate only to the biometric type values and encodings. Conformance requirements are specified in Clause 5.

Information technology — Performance testing of biometric template protection schemes

ISO/IEC 30136:2018 supports evaluation of the accuracy, secrecy, and privacy of biometric template protection schemes. It establishes definitions, terminology, and metrics for stating the performance of such schemes. Particularly, this document establishes requirements for the measurement and reporting of: - theoretical and empirical accuracy of biometric template protection schemes, - theoretical and empirical probability of a successful attack on biometric template protection schemes (single or multiple), and - the information leaked about the original biometric when one or more biometric template protection schemes are compromised. ISO/IEC 30136:2018 also gives guidance on measuring and reporting diversity and unlinkability of templates. ISO/IEC 30136:2018 does not: - establish template protection schemes; - address testing of traditional encryption schemes.

Information technology — Biometric data interchange formats — Part 13: Voice data

ISO/IEC 19794-13:2018 specifies a data interchange format that can be used for storing, recording, and transmitting digitized acoustic human voice data (speech) assumed to be from a single speaker recorded in a single session. This format is designed specifically to support a wide variety of Speaker Identification and Verification (SIV) applications, both text-dependent and text-independent, with minimal assumptions made regarding the voice data capture conditions or the collection environment. Other uses for the data encapsulated in this format, such as automated speech recognition (ASR), may be possible, but are not addressed in this documnet. This document also does not address handling of data that has been processed to the feature or voice model levels. No application-specific requirements, equipment, or features are addressed in this document. This document supports the optional inclusion of non-standardized extended data. This document allows both the original data captured and digitally-processed (enhanced) voice data to be exchanged. A description of any processing of the original source input is intended to be included in the metadata associated with the voice representations (VRs). This document does not address data streaming. Provisions that stored and transmitted biometric data be time-stamped and that cryptographic techniques be used to protect their authenticity, integrity and confidentiality are out of the scope of this document. Information formatted in accordance with this document can be recorded on machine-readable media or can be transmitted by data communication between systems. A general content-oriented subclause describing the voice data interchange format is followed by a subclause addressing an XML schema definition. ISO/IEC 19794-13:2018 includes vocabulary in common use by the speech and speaker recognition community, as well as terminology from other ISO standards.

Information technology — Biometric presentation attack detection — Part 2: Data formats

ISO/IEC 30107-2:2017 defines data formats for conveying the mechanism used in biometric presentation attack detection and for conveying the results of presentation attack detection methods. The attacks considered in the ISO/IEC 30107 series take place at the sensor during the presentation and collection of the biometric characteristics. Any other attacks are outside the scope of this document. ISO/IEC 30107-2:2017 contains the following data formats: a binary format and an XML schema. The data interchange formats in this document are generic, in that they may be applied and used in a wide range of application areas. No application-specific requirements are addressed here. Provisions for the cryptographic protection of the authenticity, integrity, and confidentiality of stored and transmitted presentation attack detection data are beyond the scope of this document. NOTE While addressing security is out of the scope of this document, PAD data may be protected by encoding them into a biometric information record (see ISO/IEC 19785-1) that includes an optional security block.

Information technology — Conformance testing for the biometric application programming interface (BioAPI) — Part 1: Methods and procedures

ISO/IEC 24709-1:2017 specifies the concepts, framework, test methods, and criteria required to test conformity of biometric products claiming conformance to BioAPI (see ISO/IEC 19784-1). Guidelines for specifying BioAPI conformance test suites, writing test assertions, and defining procedures to be followed during the conformance testing are provided. ISO/IEC 24709-1:2017 is concerned with conformance testing of biometric products claiming conformance to BioAPI (see ISO/IEC 19784-1). It is not concerned with testing other characteristics of biometric products or other types of testing of biometric products (i.e. acceptance, performance, robustness, security, etc.) Testing by means of test methods, which are specific to particular biometric products, are not the subject of ISO/IEC 24709-1:2017. ISO/IEC 24709-1:2017 is applicable to the development and use of conformance test method specifications, BioAPI conformance test suites, and conformance testing programs for BioAPI-conformant products. It is intended primarily for use by testing organizations, but can be applied by developers and users of test assertions and test method implementations.
