Abstract: AI face-changing originates from deep forgery technology, which involves a large amount of face information and data attributes. AI face-changing has been widely used due to its high fidelity and low operating threshold. However, the abuse of this technology leads to higher risk of infringement of private rights such as copyright and personality right, information security risk and crime prevention and control risk. At present, the legal regulation of AI face-changing technology outside China mainly exists two modes: decentralized legislative regulation and unified legislative regulation. China has not yet established a systematic regulation system, which should be improved from the following aspects in the future. First, to clear that the basic regulation principle is reasonable under the premise of distinguishing application scenarios. Second, a preevent and in-event regulation system is to be established, to clarify the technical ethics of developers and the labeling and declaration obligations of producers, to ensure the right to know and consent of information subjects, and to strengthen the content review obligations of communication platforms. Third, to construct the regulatory system of data and algorithm as the core.Fourth, to strictly investigate civil legal liability and intensify criminal sanctions.
