Face deepfake technology has matured, and related cases have increased year by year, with a wide range of impacts. However, with the rise of new AIGC (such as language model text generation, AI drawing, etc.) technologies, deepfake technology will be upgraded again and expanded to more levels. These new technologies are likely to generate more criminal cases. Therefore, we will sort out the context of deepfake technology from the past to the future. Our content will cover deepfake technology demonstration, real case study, technical introduction, and introduction of deepfake identification technology.
