[研究目的]人工智能的快速发展为深度伪造信息识别研究带来了新的挑战,通过精细萃取深度伪造信息特征和充分挖掘信息特征的关联机制,可以为人工智能生成信息治理提供科学的参考依据.[研究方法]以217条国内外深度伪造案例视频为研究对象,利用程序化编码萃取深度伪造视频的信息特征,运用复杂网络和随机森林算法揭示信息特征的结构关联和影响关联,并构建融合深度伪造信息特征及关联计算的动态理论模型.[研究结论]结果发现深度伪造信息具有预警特征、技术特征、内容特征和参与特征4个聚合维度、12个二阶特征和125个子特征,其中技术特征和预警特征是区别于一般虚假信息的独特特征.预警特征是结构关联网络中的关键节点,与技术特征强关联;参与特征和内容特征结构关联度高;深度伪造告知和技术与深度伪造信息关注度之间存在强烈的关联性.
Information Features Extraction and the Correlation Calculation of the Deep Fake Videos
[Research purpose]The rapid development of artificial intelligence has brought about new challenges to the research of deep fake information recognition.This paper can provide a scientific support for AI generated information governance through fine extraction of deep fake information features and sufficient exploration of the correlation mechanism of information features.[Research method]With the case of 217 domestic and overseas deep fake videos as the research object,using procedural coding to extract the information features of deep fake videos,and applying complex network and random forest algorithms to reveal the structural and causal correlation of the infor-mation features,we construct a comprehensive model that integrates the information features and its correlation effects.[Research conclu-sion]The results show that deep fake information has 4 aggregated dimensions including warning feature,technical feature,content feature and engagement feature,with 12 second-order features and 125 sub-features.The technical feature and warning feature are the unique fea-tures distinguishing from general disinformation.While warning feature is the key node in the structural association network and strongly related to the technical feature,and engagement feature and content feature are high in structural correlation.We also find that there is a strong causal correlation between the deep fake notification technology and the attention paid to the deep fake information.
