Overview
ISO/IEC 30106-4:2019 - Information technology - Object oriented BioAPI - Part 4: C++ implementation defines an object‑oriented C++ interface for implementing BioAPI components. The standard specifies a C++ framework and C++ BSP (Biometric Service Provider) interface that mirror the architecture and components described in ISO/IEC 30106-1, while maintaining semantic equivalence with the Java and C# implementations (ISO/IEC 30106-2 and ISO/IEC 30106-3). ISO/IEC 30106-4:2019 is aimed at enabling consistent, interoperable biometric system components across different programming languages.
Key Topics and Technical Requirements
- C++ framework and BSP interfaces: Defines the structure and naming of classes and interfaces for a BioAPI C++ implementation so that BSPs and frameworks interoperate.
- Data types and constants: Covers basic data types, enumerations, and common constructs such as BioAPIData, RegistryID, UUID, and date/time handling.
- Object models and schemas: Describes C++ classes and schemas including ACBioParameters, BIR (Biometric Information Record), BSPSchema, BFPSchema, UnitSchema, UnitList, and GUI bitmap representations.
- Unit and BFP support interfaces: Specifies object‑oriented interfaces for Unit support (IArchive, IComparison, IProcessing, ISensor) and BFP-level behaviour.
- BFP, BSP and Framework level interfaces: Defines interfaces such as IBFP, IBSP, IComponentRegistry, and IFramework for component registration, lifecycle, properties, events and methods.
- Application interaction and error handling: Includes application interaction patterns and exception types (e.g., BioAPIException) for consistent runtime behavior.
- Language parity: Maintains name and interface structure compatibility with the Java and C# parts, even when parameter types differ.
Practical Applications and Who Uses It
- Biometric SDK and BSP vendors: Implementers building C++ biometric service providers that must interoperate with an object‑oriented BioAPI framework.
- System integrators and solution architects: Teams integrating multi‑vendor biometric components into security, access control, or identity platforms.
- Enterprise and government IT: Organizations standardizing biometric modules to ensure portability and consistent behavior across platforms.
- Developers and researchers: C++ developers implementing biometric algorithms, sensor interfaces, or unit-level services who need a standardized API for interoperability.
Benefits include improved interoperability, reduced integration cost, and easier cross‑language porting of biometric components.
