Information technology — Biometric application programming interface — Part 1: BioAPI specification

Information technology — Biometric application programming interface — Part 1: BioAPI specification

ISO/IEC 19784-1:2006 provides a defined interface that allows a software application to communicate with (utilize the services of) one or more biometric technologies. It includes a high-level generic biometric authentication model suited to a broad range of biometrically enabled applications and to most forms of biometric technology. An architectural model is described which enables components of a biometric system to be provided by different vendors, and to interwork through fully-defined Application Programming Interfaces (APIs), corresponding Service Provider Interfaces (SPIs), and associated data structures. ISO/IEC 19784-1:2006 covers the basic biometric functions of enrollment, verification and identification, and includes a database interface to allow an application to manage the storage of biometric records. Conformance requirements are identified and informative annexes, including sample code, are provided. ISO/IEC 19784-1:2006 specifies a biometric data structure which is compatible with ISO/IEC 19785 and 19794.

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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 19784-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 37, Biometrics.
ISO/IEC 19784 consists of the following parts, under the general title Information technology — Biometric
application programming interface:
⎯ Part 1: BioAPI specification
⎯ Part 2: Biometric archive function provider interface
This is the first ISO/IEC standard on BioAPI. Previous versions were published by ANSI and the BioAPI
Consortium. As the last official non-ISO release was designated Version 1.1, this ISO/IEC 19784-1 version is
designated Version 2.0. This is to distinguish the versions of BioAPI products in the marketplace.

Introduction
This part of ISO/IEC 19784, the BioAPI specification, provides a high-level generic biometric authentication
model suited to most forms of biometric technology. No explicit support for multimodal biometrics is currently
provided.
An architectural model is described which enables components of a biometric system to be provided by
different vendors, and to interwork through fully-defined Application Programming Interfaces (APIs).
A key feature of the architecture is the BioAPI Framework, which supports calls by one or more application
components (provided by different vendors, and potentially running concurrently) using the BioAPI API
specification. The BioAPI Framework provides this support by invoking (through a Service Provider Interface,
SPI) one or more biometric service provider (BSP) components (provided by different vendors, and potentially
running concurrently) which can be dynamically loaded and invoked as required by an application component.
At the lowest level there is hardware or software that performs biometric functions such as capture, matching,
or archiving. These parts

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 — Use of biometrics in video surveillance systems — Part 1: System design and specification

The ISO 30137 series is applicable to the use of biometrics in VSS (also known as Closed Circuit Television or CCTV systems) for a number of scenarios, including real-time operation against watchlists and in post event analysis of video data. In most cases, the biometric mode of choice will be face recognition, but this document also provides guidance for other modalities such as gait recognition. This document: — defines the key terms for use in the specification of biometric technologies in a VSS, including metrics for defining performance; — provides guidance on selection of camera types, placement of cameras, image specification etc. for the operation of a biometric recognition capability in conjunction with a VSS; — provides guidance on the composition of the gallery (or watchlist) against which facial images from the VSS are compared, including the selection of appropriate images of sufficient quality, and the size of the gallery in relation to performance requirements; — makes recommendations on data formats for facial images and other relevant information (including metadata) obtained from video footage, used in watchlist images, or from observations made by human operators; — establishes general principles for supporting the operator of the VSS, including user interfaces and processes to ensure efficient and effective operation, and highlights the need to have suitably trained personnel; — highlights the need for robust governance processes to provide assurance that the implemented security, privacy and personal data protection measures specific to the use of biometric technologies with a VSS (e.g. internationally recognizable signage) are fit for purpose, and that societal considerations are reflected in the deployed system. This document also provides information on related recognition and detection tasks in a VSS such as: — estimation of crowd densities; — determining patterns of movement of individuals; — identification of individuals appearing in more than one camera; — use of other biometric modalities such as gait or iris; — use of specialized software to infer attributes of individuals, e.g. estimation of gender and age; — interfaces to other related functionality, e.g. video analytics to measure queue lengths or to alert for abandoned baggage.

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.

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.

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 — Biometrics — Overview and application

ISO/IEC TR 24741:2018 describes the history of biometrics and what biometrics does, the various biometric technologies in general use today (for example, fingerprint recognition and face recognition) and the architecture of the systems and the system processes that allow automated recognition using those technologies. It also provides information about the application of biometrics in various business domains such as border management, law enforcement and driver licensing, the societal and jurisdiction considerations that are typically taken into account in biometric systems, and the international standards that underpin their use.
