ISO/IEC 24708:2008规定了一组消息（BIP消息）的语法、语义和编码，这些消息使符合BioAPI的应用程序（参见ISO/IEC 19784-1）能够跨节点或进程边界请求符合BioAPI标准的生物特征服务提供商（BSP）中的生物特征操作，并通知这些远程BSP中的事件。它还规定了BioAPI框架（ISO/IEC 19784-1中规定）的架构和行为的扩展，该框架支持BIP消息的创建、处理、发送和接收。 它适用于BioAPI的所有分布式应用。

ISO/IEC 24708:2008 specifies the syntax, semantics, and encodings of a set of messages (BIP messages) that enable a BioAPI-conforming application (see ISO/IEC 19784-1) to request biometric operations in BioAPI-conforming biometric service providers (BSPs) across node or process boundaries, and to be notified of events originating in those remote BSPs. It also specifies extensions to the architecture and behaviour of the BioAPI framework (specified in ISO/IEC 19784-1) that supports the creation, processing, sending and reception of BIP messages. It is applicable to all distributed applications of BioAPI.
