AI face-swapping technology, known as Deepfake, has gradually become widespread against the backdrop of rapid technological advancement, attracting significant attention. A strikingly realistic live stream video of Musk has sparked heated discussions online, drawing a large audience and revealing the potential and risks of the technology. Deepfake technology is not only used for live streams but can also create highly realistic social media videos, such as a fake Musk TikTok account, which has garnered an impressive number of likes and shares, making it hard to distinguish truth from falsehood. However, the application of this technology has also led to a series of issues, particularly the increased risk of telecommunication fraud.

As the realism of AI-generated images increases, people begin to question the authenticity of videos. A video released by 'Quantum Bit' on Bilibili discusses how to identify AI-produced videos, triggering widespread interest. The video introduces some intuitive recognition methods, such as observing whether characters' movements and expressions are natural, as well as the coordination of voice, mouth shapes, and emotions. In the face of a vast number of videos, AI recognition technology becomes crucial. The traces left by AI face swapping technology during the splicing process serve as important clues for AI recognition. The research team developed classifiers from dimensions such as models, motion, and geometry.
