Vascular biometric recognition technology has been developed for many years. With the development of imaging equipment technology, blood vessel images collected from different parts of the human body

Like new technologies are constantly improving, some reliable biometric identification methods have been widely used. However, due to the lack of

Interoperable standard formats for information exchange have resulted in little exchange of vascular biometric image information between devices from different vendors.

This document specifies the specifications for the exchange of biometric image information of human blood vessels, including specific attributes, storage and transmission of angiogenesis

The data record format, sample record and conformity standard and test method of object characteristic image.

This document is suitable for the exchange of raw or processed vascular biometric images. It is suitable for applications that are not limited by the required storage capacity

use. The trade-off between resources required for data storage or transmission and increased data quality/accuracy is considered. Its basic purpose is to enable various

Object feature recognition technology can use this document for image exchange.

Appendix C provides compliance testing methods for the interchange formats defined in this document. Appendix D gives the vascular image data record

example. In addition, this document supports both binary encoding and XML encoding to support a range of user requirements. For XML, this document will

Meets the requirements of modern IT architectures; using binary encoding, this file will be able to be used in environments with limited bandwidth or storage. Appendix E refers to

example.

Vascular biometric identification technology can use the back of the hand, palm and fingers, etc., according to the different objects collected, the data format structure, requirements, etc.

Therefore, the data exchange format for vascular biometric identification is specified in parts according to different acquisition objects and image types.

This document specifies a data record interchange format for the storage, recording and transmission of vascular biological data from one or more regions of the human body.

characteristic information. This document specifies the content, format and units of measurement for image exchange. The exchange format consists of mandatory and optional items, including scanning

scan parameters, compressed or uncompressed image descriptions, and vendor-specific information.

The data exchange format specified in this document can be recorded on a machine-readable medium or transmitted on a data communication device.

This document also specifies conformance test methods, test assertions and test procedures applicable to the above-mentioned data record exchange formats. include.

--- Test assertion according to the structure of the blood vessel image data format specified in Chapter 8 of this document;

--- Test assertion internal compliance by checking the types of values that may be contained in each field;

---Semantic assertion test.

The compliance test methods specified in this document do not include.

--- other characteristics of biometric products or other types of testing (eg, acceptance, performance, stability, security);

--- Conformity testing that produces data records that do not comply with the provisions of this document.

This document is applicable to blood vessel biometric image data exchange by vascular biometric identification manufacturers in the storage, recording and transmission links.

At the same time, it is suitable for compliance testing by testing agencies, end users and vascular biometric identification manufacturers.
