Information technology. Biometric data interchange formats. Vascular image data | Status: Confirmed, Current

1 Scope This part of ISO/IEC 19794 specifies an image interchange format for biometric person identification or verification technologies that utilize human vascular biometric images and may be used for the exchange and comparison of vascular image data. It specifies a data record interchange format for storing, recording, and transmitting vascular biometric information from one or more areas of the human body. It defines the contents, format, and units of measurement for the image exchange. The format consists of mandatory and optional items, including scanning parameters, compressed or uncompressed image specifications and vendor-specific information. Information compiled and formatted in accordance with this part of ISO/IEC 19794 can be recorded on machine-readable media or may be transmitted by data communication facilities. This part of ISO/IEC 19794 also specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to this part of ISO/IEC 19794. Specifically, it establishes

• — test assertions of the structure of the vascular image data format as specified in Clause 8 of this part of ISO/IEC 19794 (Type A Level 1 as defined in ISO/IEC 19794‑1:2011/Amd.1),
• — test assertions of internal consistency by checking the types of values that may be contained within each field (Type A Level 2 as defined in ISO/IEC 19794‑1:2011/Amd.1),
• — tests of semantic assertions (Type A Level 3 as defined in ISO/IEC 19794‑1:2011/Amd.1).

The conformance testing methodology specified in this part of ISO/IEC 19794 does not establish

• — tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security),
• — tests of conformance of systems that do not produce data records conforming to the requirements of this part of ISO/IEC 19794.
