标准摘要
[中文适用范围]： ISO/IEC 19794的这一部分规定了生物识别人员识别或验证技术的图像交换格式，该技术利用人体血管生物识别图像，并可用于血管图像数据的交换和比较。 它指定了一种数据记录交换格式，用于存储、记录和传输来自人体一个或多个区域的血管生物特征信息。 它定义了图像交换的内容、格式和测量单位。 该格式由强制和可选项目组成，包括扫描参数、压缩或未压缩图像规格以及供应商特定信息。 根据 ISO/IEC 19794 本部分编译和格式化的信息可以记录在机器可读介质上或可以通过数据通信设施传输。 符合 ISO/IEC 19794 这一部分的血管生物识别图像数据旨在嵌入到 ISO/IEC 19785-1 中指定的 CBEFF 生物识别数据块 (BDB) 中符合 CBEFF 的结构中。 [外文原描述]： ISO/IEC 19794-9:2007 defines the exchange of human vascular biometric image information. It defines a specific definition of attributes, a data record format for storing and transmitting vascular biometric images and certain attributes, a sample record and conformance criteria. ISO/IEC 19794-9:2007 is intended for applications requiring the exchange of raw or processed vascular biometric images. It is intended for applications not limited by the amount of storage required. It is a compromise or a trade-off between the resources required for data storage or transmission and the potential for improved data quality/accuracy. Basically, it is to enable various algorithms to identify or verify the vascular biometric image data transferred from other image sources. Currently available vascular biometric technologies that may utilize ISO/IEC 19794-9:2007 for image exchange are technologies that use the back of the hand, palm and finger.
