ISO/IEC 19785-3:2007规定了几种符合ISO/IEC 19785-1要求的用户格式。ISO/IEC 19785-1定义了标准化生物特征信息记录（BIR）的基本结构，该结构由三部分组成:标准生物特征头（SBH）、生物特征数据块（BDB）和安全块（SB）。CBEFF还定义了几个可用于SBHs和SBs的数据元素及其标准化抽象值（CBEFF将BDB视为不透明数据）。CBEFF还建立了机制，通过这些机制，CBEFF称为“赞助人”的组织可以指定和发布BIR格式规范，这些规范又被称为“赞助人格式”。CBEFF使用户能够开发完全标准化和可互操作的BIR规范，但又特别适合特定应用环境的要求。CBEFF为仅包含一个BDB（简单BIR）和至少包含一个BDB（复杂BIR）的BIR定义规则。CBEFF定义了用于标识BDB格式及其安全属性（加密和完整性）的强制性数据元素。所有其他CBEFF定义的数据元素和抽象值都是可选的。CBEFF使用户能够根据应用程序环境的要求定义额外的数据元素和抽象值

ISO/IEC 19785-3:2007 specifies several patron formats that conform to the requirements of ISO/IEC 19785-1.ISO/IEC 19785-1 defines a basic structure for standardized biometric information records (BIRs) that consists of three parts, the standard biometric header (SBH), the biometric data block (BDB), and the security block (SB). CBEFF also defines several data elements and their standardized abstract values that can be used in SBHs and SBs (CBEFF treats the BDB as opaque data). CBEFF also establishes mechanisms by which organizations, called “patrons” by CBEFF, can specify and publish BIR format specifications, which are in turn called “patron formats”. CBEFF enables patrons to develop BIR specifications that are fully standardized and interoperable, yet are specifically adapted to the requirements of a particular application environment.CBEFF defines rules for BIRs that contain only one BDB (simple BIR) and that contain at least one BDB (complex BIR). CBEFF defines mandatory data elements that identify the format of a BDB and its security attributes (encryption and integrity). All the other CBEFF-defined data elements and abstract values are optional. CBEFF enables patrons to define additional data elements and abstract values as required by the application environment
