Recently, artificial intelligence has been successfully used in fields, such as computer vision, voice, and big data analysis. However, various problems, such as security, privacy, and ethics, also occur owing to the development of artificial intelligence. One such problem are deepfakes. Deepfake is a compound word for deep learning and fake. It refers to a fake video created using artificial intelligence technology or the production process itself. Deepfakes can be exploited for political abuse, pornography, and fake information. This paper proposes a method to determine integrity by analyzing the computer vision features of digital content. The proposed method extracts the rate of change in the computer vision features of adjacent frames and then checks whether the video is manipulated. The test demonstrated the highest detection rate of 97% compared to the existing method or machine learning method. It also maintained the highest detection rate of 96%, even for the test that manipulates the matrix of the image to avoid the convolutional neural network detection method.
最近,人工智能已经成功应用于计算机视觉、语音和大数据分析等领域。然而,由于人工智能的发展,也出现了各种安全、隐私和伦理问题。其中一个问题是深度伪造。深度伪造是深度学习和伪造的组合词。它是指使用人工智能技术或制作过程本身创建的假视频。深度伪造可被用于政治滥用、色情和虚假信息。本文提出了一种通过分析数字内容的计算机视觉特征来确定完整性的方法。该方法提取相邻帧的计算机视觉特征的变化率,然后检查视频是否被操纵。与现有方法或机器学习方法相比,该测试的检测率最高可达 97%。即使对于操纵图像矩阵以避免卷积神经网络检测方法的测试,它也保持了最高的 96%的检测率。
