This part is part 2 of GB/T 26237.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section refers to ISO/IEC JTC1/SC37FCD "Information technology Biometrics data exchange format Part 2.

Introduction

GB/T 26237 is used to support interoperability and data exchange between biometric applications and systems. The standard details of the understanding the application of biometrics in the identification of personal identification systems, whether applied in an open system environment or by a single application Closed system completed. Additional information on this standard is available in GB/T 26237.1-2010.

In order to implement the interoperable biometric system, this part establishes the data exchange format of the detail point. It is with the generation Management, and detailed data processing of the system or unit. The use of detail points as fingerprint data is a representation in many applications Domain widely used technology.

This section defines the details of extracting key points (referred to as fine nodes) from the fingerprint ridge pattern. This includes identifying fine points the description of the type, the method of locating the minutiae on the image, the definition of the coordinate system used, and the angle calculation method associated with each detail point.

Information technology - Biometrics data exchange format Part 2. Fingerprint detail data

1 Scope

This part of GB/T 26237 specifies the concept and data format used in the fingerprint-based fingerprint representation of GB/T 26237.

This part is also generic and can be used in areas involving automatic fingerprint recognition. GB/T 26237 also contains the relevant terms of the set How to determine the description of the details of the point, for the general use and card to use the required data format and compliance information. In the appendix to this section Provides the steps, values, and decision parameters for matching.

Although the fingerprint and palmprint image data are included in GB/T 26237.4, this part only includes fingerprints and does not apply to palm prints.

2 Compliance

Biometric records that meet the following regulatory requirements comply with this part of GB/T 26237.

a) The relationship between the data structure, the data value, and the data element is defined by Chapter 8 (Finger Detail Record Format) and Chapter 9 (Fingerprint detail point card on the biometric feature comparison format) to define;

b) The relationship between the data values and the biometric input data generated from the biometric data records is defined by Chapter 8 (Hand Refers to the detail node record format) and Chapter 9 (Fingerprint Fingerprints on the biometric feature comparison format) to define.

If the output of the biometric data record conforms to this part (as defined above) and is consistent with the execution of the system the system that generates biometric data records will follow this section. The system does not have to have all the possibilities to cover this part of the cover Aspects of the biometric data record, only need to generate the implementation of the Declaration of Conformity (ICS) supported by the record. The implementation of the declaration of conformity should be made this is supplemented by a template provided by ISO/IEC 29109-2 (Compliance Test Method for Biometric Identification Data Exchange Records).
