Introduction

This document defines a biometric fusion information format that establishes a machine-readable data format to describe Statistics of the alignment scores entered during the merge process. GB/T 41814 "Information Technology Biometric Calibration, Enhancement and Fusion Data" It is intended to consist of the following parts. --- Part 1.Fusion information format. The purpose is to specify the format of information fusion between biometric identification systems, which is suitable for biometric identification systems. Design and use of a score-level fusion strategy for a signature recognition system. This document defines the most common and easy-to-use fusion method. graded fusion. The method utilizes two or more systems to deal with an individual's Biometric information and match the processed information with at least one registered sample, and then output a scalar alignment score. these have The scores can be real scores (same person) or counterfeit scores (different people), and then design a fusion scheme to combine the scores for further Define the class boundary between real and fake scores. The distribution of alignment scores depends on the biometric alignment subsystem. The range of scores and the shape of the distribution can vary widely from system to system. Two common fusion methods are as follows. --- In the classification-based process, the existing alignment scores are directly combined to output a decision or score. ---In the normalization-based process, each score needs to be converted to a common interval before fusion. Based on mean and standard deviation Simple normalization methods for statistical parameters such as differences are sometimes effective, while complex normalization methods require knowledge of the overall distribution of scores. Holds any of the common conversion forms. This document supports a Modular approach to biometric system integration. In this method, the alignment and fusion algorithms are still protected by their respective intellectual property rights. Therefore, this document envisages the possibility of an application that utilizes two or more basic acquisition and alignment techniques (e.g. hand shape and fingerprints) to generate a score each, which are then fed into a Fusion module. The logical role of each record in the conceptual multimodal fusion process is shown in Figure 1.
