Introduction

The process of presenting prosthetic or human features to the biometric acquisition subsystem in a manner that may interfere with the intended strategy of the biometric system.

This process is called a presentation attack. GB/T 41815 focuses on automatic detection mechanisms for presentation attacks. These mechanisms are called presence attack detection

(PAD) mechanism.

This document constructs a common data format for conveying the type of attack detection method and the results of the attack detection method. this document

Specifies the meaning of the data elements in the presentation attack detection data format, see clause 5.These include an extensible specification based on ASN.1

Tagged binary PAD data format, see A.1 in Appendix A; text PAD data format defined based on XML schema, see Appendix

A.2 in A. Normative Appendix A includes formal coding specifications, and informative Appendix B gives coding examples.

GB/T 41815 "Information Technology Biometric Recognition Present Attack Detection" stipulates the present attack detection phase in the field of biometric identification.

The relevant framework, data format, and test-related content are used to facilitate the evaluation of the design of the attack detection function and its ability.

GB/T 41815 is intended to consist of three parts.

--- Part 1.Framework. The purpose is to establish an overall framework related to attack detection in biometric identification systems.

--- Part 2.Data format. The purpose is to standardize the data format for presenting attack detection.

--- Part 3.Testing and reporting. The purpose is to clearly present the various factors that need to be considered in the assessment of attack detection capabilities and the evaluation

Evaluation principles and methods.

To standardize the objects related to attack detection, it is necessary to first clearly present the attack detection framework as a whole to guide the attack detection.

The definition of classification and tools, secondly, in order to exchange and share related data elements, it is necessary to define a clear and unified data format, and finally in the

When evaluating the presentation attack detection capability, it is necessary to clarify the test object, test environment and test indicators to guide the presentation attack detection capability.

Conduct scientific and objective assessments.
