[中文适用范围]： 本部分 ISO/IEC 19794 规定了用于存储、记录和传输一个或多个手指或手掌图像区域信息的记录交换格式。这可用于手指图像数据的交换和比较。它定义了用于交换手指图像数据的内容、格式和测量单位，这些数据可用于对主体进行注册、验证或识别。信息包括各种必选和可选项目，包括扫描参数、压缩或未压缩图像以及特定于供应商的信息。这些信息旨在供依赖基于手指图像区域信息的自动化设备和系统进行识别或验证的组织之间进行交换。根据本部分 ISO/IEC 19794 编译和格式化的信息可以记录在机器可读介质上，也可以通过数据通信设施传输。 [外文原描述]： ISO/IEC 19794-4:2011 specifies a data record interchange format for storing, recording, and transmitting the information from one or more finger or palm image areas within an ISO/IEC 19785-1 data structure. This can be used for the exchange and comparison of finger image data. It defines the content, format, and units of measurement for the exchange of finger image data that may be used in the verification or identification process of a subject. The information consists of a variety of mandatory and optional items, including scanning parameters, compressed or uncompressed images and vendor-specific information. This information is intended for interchange among organizations that rely on automated devices and systems for identification or verification purposes based on the information from finger image areas. Information compiled and formatted in accordance with ISO/IEC 19794-4:2011 can be recorded on machine-readable media or may be transmitted by data communication facilities.
