什么是指纹模板格式? [英] What is fingerprint template format?

问题描述

我正计划开发一个集成指纹扫描仪的系统.通过阅读一些sdk，我总是会遇到模板格式，例如: ANSI INCITS 378-2004和ISO/IEC 19794-2:2005

I'm planning to develop a system integrating fingerprint scanner. By reading some sdk's, I always encounter template format such as: ANSI INCITS 378-2004 and ISO/IEC 19794-2:2005

我很难理解它.我知道模板是用来存储指纹的术语，但是这些格式彼此之间有什么区别，模板是否来自细节?

I was having hard time understanding it. I know template is the term used to store fingerprint, but how do these format differ from each other and does template came from minutiae?

推荐答案

您提到的生物特征指纹模板格式已经标准化并且被广泛接受，比如说编码"类型的指纹模板详细信息数据整理是独立的指纹读取器扫描仪制造商可以用来保存指纹数据以进行存档.组织可以决定对所有已保存的指纹数据使用ANSI 381，而与用于以下操作的任何类型的指纹读取器无关. X部门，并选择以ISO 19794-2格式保存Y部门的所有手指数据.它们基于其基础编码而彼此不同，并且即使从同一个人的指纹来看，一种格式也不会与另一种格式匹配.至少从我作为生物识别软件解决方案开发商的经验来看，这就是我所观察到的.

The biometric fingerprint template formats you mentioned are standardized and widely accepted end let's say like 'encoding' type of the collation of a fingerprint template's minutia data that independent fingerprint reader scanners manufacturers can use to save fingerprint data for archiving. An organization can decide to use ANSI 381 for all saved fingerprint data irrespective of any type of fingerprint reader scanner used for e.g. department X and opt to save all finger data for department Y in ISO 19794-2 format. They differ from each other based on their underlying encoding and one format will not match with that of another even if from same person's fingerprint. At least from my experience as a developer of biometric software solutions, that is what I have observed.

您可以从Source AFIS项目中了解有关ISO 19794-2的一些信息，网址为 https://sourceafis.machinezoo.com/.

2019年6月更新(由所提及网站的作者撰写):此处描述了ANSI 378(和部分ISO 19794-2)的实际格式:

June 2019 update (by author of the mentioned website): Actual format of ANSI 378 (and partially ISO 19794-2) is described here: https://templates.machinezoo.com/. That should clear any doubt about what is in these files.
