ISO/IEC 30106的这一部分规定了一组定义OO和PI的接口的体系结构。ISO/IEC 30106本部分中定义的组件包括框架、生物识别服务提供商（BSP）、生物识别功能提供商（BFP）和组件注册表。 注:这些组件中的每一个都有ISO/IEC 19784-1中规定的等效组件，因为OO BioAPI旨在作为ISO/IEC 30106本部分的OO解释。 因此，ISO/IEC 30106的这一部分在概念上等同于ISO/IEC 19784-1。ISO/IEC 30106本部分中的概念（例如，BioAPI_单元和组件注册）与ISO/IEC 19784-1中的概念具有相同的含义。虽然ISO/IEC 30106这一部分的概念等同于ISO/IEC 19784-1，但函数之间传递的参数和函数调用顺序存在差异。 这些差异的存在是为了利用面向对象编程语言提供的特性。交叉引用:ISO/IEC 2382-37:2017ISO/IEC 19785-3:2015ISO/IEC 19785-1:2015IEC 19784-1:2006包含以下内容:修订，2019年6月

This part of ISO/IEC 30106 specifies an architecture for a set of interfaces which define the OO BioAPI. Components defined in this part of ISO/IEC 30106 include a framework, Biometric Service Providers (BSPs), Biometric Function Providers (BFPs) and a component registry. NOTE Each of these components have an equivalent component specified in ISO/IEC 19784-1 as the OO BioAPI is intended to be an OO interpretation of this part of ISO/IEC 30106. For this reason, this part of ISO/IEC 30106 is conceptually equivalent to ISO/IEC 19784-1. Concepts present in this part of ISO/IEC 30106 (for example, BioAPI_Unit and component registry) have the same meaning as in ISO/IEC 19784-1. While the conceptual equivalence of this part of ISO/IEC 30106 will be maintained with ISO/IEC 19784-1, there are differences in the parameters passed between functions and the sequence of function calls. These differences exist to take advantage of the features provided by Object Oriented Programming Languages.Cross References:ISO/IEC 2382-37:2017ISO/IEC 19785-3:2015ISO/IEC 19785-1:2015IEC 19784-1:2006Incorporates the following:Amendment, June 2019
