网络言论取证技术综述

近年来，人们越来越依赖于公共互联网平台进行信息的自由发布和获取。与此同时，网络空间虚假言论的泛滥也日益严峻，给人们的日常生活和社会治理带来了艰巨的挑战。因此，网络言论取证成为了一个亟需解决的难题。近几年，随着深度神经网络技术的发展，同时给网络虚假言论生成和取证技术带来了新的发展活力，使得这两种对抗技术都得到了快速发展。本文主要关注网络言论的取证技术，分别从文本和语音两方面综述了近些年网络言论取证相关的研究成果。在虚假文本取证方面，本文分别从文本内容真实性校验、文本语义特征分析以及传播模式分析这三个角度综述相关研究成果。在虚假语音取证方面，本文首先介绍了当前语音合成、语音转换延伸等技术的发展现状，然后综述了语音鉴伪和取证技术的最新研究工作。我们希望本文的综述能帮助相关领域研究人员更好地了解网络言论取证领域最新的研究进展，以便研究出更先进的技术并推动该领域的持续进步。 

A Survey for Fake Internet Remarks Forensic Technology

In recent years, people have increasingly relied on public Internet platforms for the free release and access of information. At the same time, the proliferation of fake information in cyberspace has become increasingly severe, bringing arduous challenges to people's daily lives and social governance. Therefore, the effective identification of fake information in cyberspace has become an urgent problem to be solved. In recent years, with the development of deep neural network technology, it has also brought new development vitality to false information generation and detection technology, which has led to the rapid development of these two countermeasures. This paper mainly focuses on the detection and forensics technology of fake remarks on the Internet, and summarizes the research results related to fake remarks detection and forensics on the text and voice respectively. This paper mainly focuses on the forensic technologies of fake Internet remarks, and summarizes the related works from two aspects: text and voice. In terms of fake text forensics, this paper summarizes related researches from three perspectives: text content authenticity verification, text semantic feature analysis, and communication mode analysis. In terms of fake speech forensics, this paper first introduces the current development of speech synthesis, speech conversion extension and other technologies, and then summarizes the latest research works on speech authentication and forensics technology. We hope that this review can help researchers in relevant fields better understand the latest research progress in the field of fake Internet remarks forensics, so as to develop more advanced technology and promote the continuous progress in this field.
