Since September 1, the Measures for the Identification of Synthetic Content Generated by Artificial Intelligence has been officially implemented. All AI generated text, pictures, videos and other content must be added with explicit or implicit identification. Internet platforms have responded to the new rules by modifying user protocols, restricting the flow of off shelf illegal content and other measures. This action of "labeling AI content" may seem like a small incision in technological governance, but it is actually a crucial step in rebuilding trust in the digital age. In the information flood of the digital world, 'reality' is becoming the scarcest resource. Once upon a time, the heartwarming videos of "cute kids washing vegetables and burning fire", in-depth analysis by "international military experts", and parenting tips from "virtual foreign early childhood education mentors" made it difficult for many users to distinguish between truth and falsehood, and even misled the public and stirred up emotions. The key to why these "AI magic" can cause trouble lies in "invisible propagation" - they wear real clothes but hide false cores. The new regulations require AI content to "reveal identity", which is equivalent to issuing a "digital ID card" to each generated content, allowing "Li Gui" to have nowhere to hide. This is not only a technological advancement, but also a response to human needs: when grandma browses the "fake grandson" video, the small words "AI technology production" are not cold prompts, but a warm barrier to protect family affection; When users browse 'Military Analysis', the small' composite 'symbol is not a denial of information, but a respect for the right to think. From a global perspective, the identification system has become the "universal language" for AI governance. Countries and regions such as the United States, the European Union, and Singapore are exploring rules for generating content labels, essentially answering a question: how to encourage technological innovation while maintaining the bottom line of authenticity and trust. The uniqueness of China's new regulations lies in the combination of "methods+mandatory national standards", which not only clarifies the responsibility chain of "who generates, who identifies", but also uses specific technical details such as "the height of video text should not be less than 5% of the shortest edge of the screen", turning abstract "norms" into operable "standards". This kind of governance wisdom that combines rigidity and flexibility is like installing a "navigation system" for AI content - it not only marks the "safe zone" of innovation, but also delineates the "warning line" of crossing boundaries. Of course, the implementation of any system may face "growing pains". Some netizens have reported that their original artwork was mistakenly judged by the platform as "suspected AI generated" and encountered flow restrictions; Some creators are also concerned that strict labeling requirements may suppress the vitality of AI technology applications. These issues remind us that to address the abuse of AI, we need to not only "plug" the loopholes of false content, but also "unblock" the channels for originality and innovation. On the one hand, the platform needs to optimize the machine review algorithm, introduce manual review and expert evaluation mechanisms, and avoid the pitfalls of a one size fits all approach; On the other hand, it is advisable to establish an "AI content whitelist" to provide traffic support for high-quality content generated in compliance, allowing "true innovation" and "fake content" to compete fairly in the sunshine. The temperature of technology lies in making people feel at ease; The art of governance lies in moderation of tension and relaxation. When AI generates content that begins to 'reveal identity', what we see is not only the progress of digital rules, but also a society's adherence to 'authenticity' and the value of trust. In the future, with the improvement of the labeling system, perhaps we will become accustomed to small prompts before each piece of AI content - it is not a constraint on technology, but a tribute to human creativity; It's not a restriction on information dissemination, but a safeguard for digital civilization. After all, all technological innovations should ultimately return to a simple purpose: to make every click more reassuring and every trust more secure. (New Society)
