AI总结:

本文综述了针对语音识别系统的后门攻击,提出评估标准与分类法,分析现有攻击与防御方法,并指出开放问题和未来研究方向。

摘要:

语音识别系统(VRSs)利用深度学习进行语音识别和说话人识别。它们已被广泛部署在各种实际应用中,从智能语音助手到电话监控和生物特征认证。然而,先前的研究揭示了VRSs易受后门攻击的脆弱性,这对VRSs的安全和隐私构成了重大威胁。不幸的是,现有文献缺乏对此主题的全面综述。本文通过针对VRSs的后门攻击进行综合调查来填补这一研究空白。我们首先概述VRSs和后门攻击,阐明其基础知识。然后,我们提出一套评估标准来评估后门攻击方法的性能。接下来,我们从不同角度提出针对VRSs的后门攻击的综合分类法,并分析不同类别的特征。之后,我们全面回顾现有的攻击方法,并基于所提出的标准分析其优缺点。此外,我们回顾经典的后门防御方法和通用音频防御技术。然后,我们讨论将它们部署在VRSs上的可行性。最后,我们指出几个开放问题,并进一步提出未来研究方向,以激励VRSs安全研究。

英文摘要:

Voice Recognition Systems (VRSs) employ deep learning for speech recognition and speaker recognition. They have been widely deployed in various real-world applications, from intelligent voice assistance to telephony surveillance and biometric authentication. However, prior research has revealed the vulnerability of VRSs to backdoor attacks, which pose a significant threat to the security and privacy of VRSs. Unfortunately, existing literature lacks a thorough review on this topic. This paper fills this research gap by conducting a comprehensive survey on backdoor attacks against VRSs. We first present an overview of VRSs and backdoor attacks, elucidating their basic knowledge. Then we propose a set of evaluation criteria to assess the performance of backdoor attack methods. Next, we present a comprehensive taxonomy of backdoor attacks against VRSs from different perspectives and analyze the characteristic of different categories. After that, we comprehensively review existing attack methods and analyze their pros and cons based on the proposed criteria. Furthermore, we review classic backdoor defense methods and generic audio defense techniques. Then we discuss the feasibility of deploying them on VRSs. Finally, we figure out several open issues and further suggest future research directions to motivate the research of VRSs security.
