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.
Vascular biometric image data that comply with this part of ISO/IEC 19794 are intended to be embedded in a
CBEFF-compliant structure in the CBEFF Biometric Data Block (BDB) as specified in ISO/IEC 19785-1.
