人体生物特征数据QR编码与识读技术研究

QR code based body biology character of digital coding and biometric identification technology

近年来,在传统安全技术受到不同程度挑战的情况下,人体生物特征验证已成为了安全验证研究的一个热点方向。文中概述了身份验证机制目前存在的问题,研究分析了三种人体生物特征数据的特点,在研究QR码特点的基础上,提出了一种基于QR码的人体生物特征安全验证和信息追溯方法。该方法首先对人体生物特征数据进行预处理以获得满足识读需求的最小数据集合,然后通过扩展了二进制编解码能力的ZXing QR模块,实现了人脸、指纹特征数据的数字化编解码,同时也展示了人体生物特征二维码的信息还原和显示等功能,达到了通过扫描人体生物特征二维码来进行身份验证的目的。实验表明:该方法应用适应性强,具有较高的安全可靠性。

In recent years,the traditional security technology is under the condition of different degrees of challenge,the human body biometric authentication has become a hotpot in the research of the security verification. This paper summarizes the present problems of the authentication mechanism,analyzes the features of the three kinds of human biometric data,on the basis of the research about the characteristics of QR codes,the paper proposes a human biometric security verification and information tracing method which is based on the QR code. Firstly,this method processes for the biological characteristics,to meet the demand of the minimum data set of discrimination,and then though the Zxing QR module whose binary decoding ability is extended,it realized the digital codec of the face,fingerprint. At the same time,it provides the function of reduction and display of the information about the biological characteristics of QR code,it also reached the purposes of authentication by scanning the human biometric QR code. The experiments show that the application has strong adaptability,safety and reliability.
