Compatibility test method.

This document is intended to provide a common, extensible data exchange format for applications that need to exchange vascular images.

The establishment of the format can provide developers with greater freedom in selecting or combining comparison algorithms, making vascular feature information no longer dependent on Modes or other types of pre-defined formats are used to adapt to images collected from different devices and with different sizes, spatial sampling rates, and grayscale ranges.

These vascular image data can contain detailed pixel information without being limited by data storage space or transmission time.

Run your own algorithm to determine whether two vascular records are from the same hand. For example, you can store the registration image in the non-the contact chip enables systems that rely on pattern-based algorithms to verify the identity of the document owner.

This file supports binary and Extensible Markup Language (XML) encoding, which can meet a range of User needs. Extensible specifications in Abstract Syntax Notation One (ASN.1) and ASN.1 SARS this document contains the following encoding rules that form the basis for encoding biometric data in binary tag-length-value format.

It is suitable for environments with limited bandwidth or storage. XML Schema Definitions (XSD) constitutes a XML-encoded Based on biometric data, encoded in XML, this document meets the requirements of modern information technology architecture.

1 Scope

This document.

---Specifies a common extensible data exchange format for representing vascular image data. one is based on the extensible format in ASN.1 the first is a tagged binary data format based on XSD, and the second is a text data format based on XSD. Both can store the same information.

---Gives an example of data record content;

---Proposed minimum requirements, recommended methods and best practices for application in data acquisition;

---Describes the conformance test method, test assertions and test procedures for vascular image data in an extensible format.

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

It is also suitable for manufacturers, testing agencies and end users to conduct compliance testing.
