Study of the noise immunity of biometric templates to external influences during transmission by mobile networks

Abstract

The article is devoted to the study of the immunity of biometric templates to interference and fading during transmission over the LTE network. The widespread use of remote biometric authentication systems, primarily in remote mobile payment systems, determines the relevance of the chosen topic, and the development of mobile networks, and, first of all, the use of technologies that are more protected from attacks like LTE increases its practical focus. However, when authentication information is transmitted, even over a secure channel, it can be subject to interference and fading. That is why it is important to study their impact on the integrity of the biometric template that will be used to authenticate the user in the system. The paper analyzes the dependence of the quality of the authentication system on the parameters of the mobile communication channel (bit error rate, signal-to-noise ratio) and the parameters of the mobile device that transmits information (MIMO scheme, code rate, modulation scheme), which improves the quality of the remote biometric authentication systems by reasonably choosing the transmission parameters and taking into account the parameters of the communication channel.
