ISO IEC 19784-1-2018 PDF

Full title and description

Information technology — Biometric application programming interface — Part 1: BioAPI specification. This International Standard specifies the BioAPI Application Programming Interface (API) and the Service Provider Interface (SPI) to enable interoperable biometric systems composed of components from multiple vendors, supporting both a framework-based BioAPI architecture and a framework‑free SPI usage model.

Abstract

ISO/IEC 19784-1:2018 defines interfaces and behaviour for biometric applications, Biometric Service Providers (BSPs), Biometric Function Providers (BFPs) and BioAPI Units so that components from different vendors can interoperate. It describes versioned BioAPI releases (major version 2 with minor releases 2.0, 2.1 and 2.2), conformance requirements and the separation of framework and framework‑free operation; it does not itself specify security or performance metrics.

General information

• Status: Published (International Standard; confirmed stage).
• Publication date: April 2018 (official ISO publication month; several national catalogs record 22–23 March 2018).
• Publisher: ISO and IEC (joint ISO/IEC standard produced under JTC 1/SC 37).
• ICS / categories: 35.240.15 (Identification cards. Chip cards. Biometrics).
• Edition / version: Edition 2 (BioAPI Major 2; supports minor 2.0, 2.1 and 2.2 feature sets).
• Number of pages: 234.

Scope

Specifies the BioAPI framework and SPI that allow multiple biometric applications and multiple service/provider components to operate together; supports both a framework-based architecture (a BioAPI Framework that dynamically loads BSPs and BFPs) and framework‑free operation where only the SPI is used. The standard is applicable across a broad range of biometric technologies and application types but intentionally excludes explicit security and large-scale performance requirements. Conformance clauses are provided for implementers.

Key topics and requirements

• BioAPI architecture: framework-based and framework‑free models.
• Definition of the BioAPI Application Programming Interface (API) and the Service Provider Interface (SPI).
• Component model: applications, Biometric Service Providers (BSPs), Biometric Function Providers (BFPs), BioAPI Units and optional Biometric Archive Function Providers (BAFPs).
• Versioning: Major 2 with defined minor releases (2.0, 2.1, 2.2) addressing GUI, fusion and security-related support features.
• Conformance statements and normative clauses for implementers (conformance requirements specified in Clause 5).
• Interoperability focus; security and performance requirements are out of scope (other standards cover those aspects).

Typical use and users

Software and hardware vendors implementing biometric modules (BSPs, BFPs, sensor providers), system integrators building multi-vendor biometric solutions, developers of biometric applications that need a standard API for portability, and organizations (government identity programs, access control, border management, large enterprise authentication) that require component-level interoperability. Researchers and test labs use the specification to validate conformance and integration.

Related standards

Other parts of the BioAPI / related families include ISO/IEC 19784-2 (Biometric archive function provider interface) and ISO/IEC 19784-4 (sensor function provider interface), as well as broader biometric data interchange and security standards such as the ISO/IEC 19794 series (biometric data interchange formats) and ISO 19092 for biometric security guidance. Implementers commonly use ISO/IEC 19784-1 together with these companion documents.

FAQ

Q: What is this standard?

A: ISO/IEC 19784-1:2018 is the BioAPI specification that defines the API and service-provider interfaces enabling interoperable biometric components and applications.

Q: What does it cover?

A: It covers the interface definitions, component model (applications, BSPs, BFPs, BioAPI Units), versioning for BioAPI 2.x, and conformance requirements to support multi-vendor interoperability; it does not set security or system performance criteria.

Q: Who typically uses it?

A: Biometric module vendors, system integrators, application developers, government identity and border agencies, and test/conformance laboratories building or validating interoperable biometric solutions.

Q: Is it current or superseded?

A: ISO/IEC 19784-1:2018 is published and listed as an active International Standard (confirmed stage) and is not shown as withdrawn or superseded as of March 2, 2026. National catalogs may show publication day details (March 22–23, 2018) while ISO’s official publication month is April 2018. Standards are subject to periodic review (typically every five years).

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO/IEC 19784 series (BioAPI). Other parts address archive interfaces, sensor function provider interfaces and related corrigenda or technical corrigenda; it also complements the ISO/IEC 19794 biometric data interchange series and other SC 37 work items.

Q: What are the key keywords?

A: BioAPI, biometric API, Service Provider Interface (SPI), Biometric Service Provider (BSP), Biometric Function Provider (BFP), interoperability, conformance, biometric units, framework-free, biometric integration.
