深度伪造与检测技术综述

深度学习在计算机视觉领域取得了重大成功,超越了众多传统的方法.然而近年来,深度学习技术被滥用在假视频的制作上,使得以Deepfakes为代表的伪造视频在网络上泛滥成灾.这种深度伪造技术通过篡改或替换原始视频的人脸信息,并合成虚假的语音来制作色情电影、虚假新闻、政治谣言等.为了消除此类伪造技术带来的负面影响,众多学者对假...

Survey on Deepfakes and Detection Techniques

Deep learning has achieved great success in in the field of computer vision, surpassing many traditional methods. However, in recent years, deep learning technology has been abused in the production of fake videos, making fake videos represented by Deepfakes flooding on the Internet. This technique produces pornographic movies, fake news, political rumors by tampering or replacing the face information of the original videos and synthesize fake speech. In order to eliminate the negative effects brought by such forgery technologies, many researchers have conducted in-depth research on the identification of fake videos and proposed a series of detection methods to help institutions or communities to identify such fake videos. Nevertheless, the current detection technology still has many limitations such as specific distribution data, specific compression ratio, and so on, far behind the generation technology of fake video. In addition, different researchers handle the problem from different angles. The data sets and evaluation indicators used are not uniform. So far, the academic community still lacks a unified understanding of deep forgery and detection technology. The architecture of deep forgery and detection technology research is not clear. In this review, we review the development of deep forgery and detection technologies. Besides, we systematically summarize and scientifically classify existing research works. Finally, we discussed the social risks posed by the spread of Deepfakes technology, analyzed the limitations of detection technology, and discussed the challenges and potential research directions of detection technology, aiming to provide guidance for follow-up researchers to further promote the development and deployment of Deepfakes detection technology.
