format and compliance test methods.

This document is intended to provide an extensible data exchange format for applications that need to exchange friction ridge images (e.g., palm print images).

The establishment of a data exchange format can provide developers with greater freedom in selecting or combining comparison algorithms, making fingerprint feature information Rely on pre-defined modes or other types to adapt to different devices, sizes, spatial sampling rates and grayscale ranges.

These fingerprint image data can contain detailed pixel information and are not limited by data storage space or transmission time.

The business can run its own algorithm to determine whether two records are from the same hand. For example, the registration image can be stored in the ID card.

The contactless chip on the document 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.
