The National Internet Information Office and four other departments issued the "Methods for Identifying AI-Generated Synthetic Content." It encourages service providers to add implicit identifiers such as digital watermarks in the generated synthetic content. If users request generated synthetic content without explicit identifiers from service providers, the service providers may provide such content after clarifying the user's identification obligations and usage responsibilities through a user agreement, and they must legally retain the information of the provided objects and related logs for no less than six months.

The introduction of the "Identification Methods" aims to address specific issues such as the abuse of AI-generated synthetic content, the rampant spread of false information, and the resulting crisis of social trust. Whether it is the inspection needs of review institutions or the compliance needs of content publishers and platforms, there is hope for opportunities under the stimulation of policies. Chen Xiaohua, Executive Dean of the Education and Science Research Institute of CHINA MOBILE, stated: "With the implementation of the 'Identification Methods,' companies that can quickly adapt to and implement the relevant requirements will gain a competitive edge in the market."
