1. What is content generated by artificial intelligence (AI)?

According to Article 3 of the Labeling Measures for Content Generated by Artificial Intelligence, content generated by AI refers to information, such as text, images, audio files, videos, and virtual scenes, that are generated or synthesized using AI technologies.

2. What types of labels are used for content generated by AI?

According to Article 3 of the Labeling Measures for Content Generated by Artificial Intelligence, labels for content generated by AI include explicit labels and implicit labels. An explicit label is added directly to the content generated by AI or the interaction UI in the form of text, audio, graphics, or others, which can be clearly perceived by users. In contrast, an implicit label is added to the AI-generated content file data by using technical measures, and is not easily noticeable to users.

3. In what scenarios should the content generated by AI be labeled?

According to Article 17 of the Provisions on the Administration of Deep Synthesis of Internet-based Information Service, deep synthesis service providers must apply prominent labels (in suitable positions or areas) to AI-generated or AI-edited content when the services may cause public confusion or misunderstanding. Such deep synthesis services include:

(1) Text generation or editing that simulates natural persons, such as intelligent dialogue and intelligent writing;

(2) Voice generation or editing, such as human voice synthesis, voice mimicry, or modifications that significantly change personal identity features;

(3) Human-related image and video generation or editing, such as face generation, face replacement, face manipulation, pose manipulation, or modifications that significantly change personal identity features;

(4) Generation or editing services such as immersive virtual scenes; and

(5) Other services that generate or significantly change information content or functions.

For deep synthesis services beyond the above categories, the deep synthesis service providers shall offer the prominent labeling function and remind deep synthesis service users that prominent labeling is available.

4. Why is it necessary to add explicit labels to the content generated by AI?

According to Article 4 of the Labeling Measures for Content Generated by Artificial Intelligence, if the generation service falls under the scope defined in the first paragraph of Article 17 of the Provisions on the Administration of Deep Synthesis of Internet-based Information Service, service providers must apply explicit labels to the content generated by AI with the following requirements met:

(1) Add a label, such as a textual notice or general symbol, at the beginning, end, or middle (at a suitable position) of the text, or display a prominent label on the interaction UI or around the text.

(2) Add a label, such as a voice prompt or rhythmic audio cue, at the beginning, end, or middle (at a suitable position) of the audio, or display a prominent label on the interaction UI.

(3) Add a prominent label at a suitable position of the image.

(4) Add a prominent label on the initial video frame, at a suitable position around the video playback area, on the end frame, or at a suitable position during the middle of the video.

(5) When presenting a virtual scene, add a prominent label at a suitable position on the initial frame or during the virtual scene service.

(6) In other content generation and synthesis service scenarios, add prominent labels based on the app characteristics.

When offering functions such as downloading, copying, and exporting the content generated by AI, service providers shall ensure that the files contain explicit labels that meet the requirements.

5. What are the specific methods for adding explicit labels to content generated by AI?

(1) Text

a. An explicit label for text content can appear as a text notice or badge.

c. A badge-style explicit label should contain "AI".

d. Explicit labels for text content shall appear at one or more of the following positions:

Note 1: The "short-long, short-short" rhythm corresponds to the Morse code representation of "AI".

d. Explicit labels for audio content shall appear at one or more of the following positions:

i. At the beginning of the audio;

ii. At the end of the audio; and/or

iii. At an appropriate position in the middle of the audio.

Note 2: The "beginning of the audio" refers to the segment before the start of the AI-generated audio content. The "end of the audio" refers to the segment after the AI-generated audio content ends.

Note 3: In high-frequency audio interaction scenarios, such as intelligent voice assistant, intelligent customer service, and intelligent navigation, the "beginning" and "end" of audio refer to the beginning and end of an interaction round.

6. Why is it necessary to add implicit labels to the file metadata of content generated by AI? What is file metadata?

(1) According to Article 5 of the Labeling Measures for Content Generated by Artificial Intelligence, service providers shall add implicit labels to the file metadata of content generated by AI in line with Article 16 of the Provisions on the Administration of Deep Synthesis of Internet-based Information Service (deep synthesis service providers shall take technical measures to add labels that do not interfere with user experience to the content generated or edited by using their services, and shall retain log information in accordance with laws, administrative regulations, and relevant national standards).

(2) File metadata refers to descriptive information embedded in the file header using a specific encoding format. It is used to record details such as the source, attributes, intended use, and copyright status of the file.

7. What are the specific methods for adding implicit labels to the file metadata of content generated by AI?

(1) An implicit label shall contain the following elements:

a. Generation label: attribute information indicating whether the content is generated or synthesized by AI;

c. Content production ID: unique content ID assigned by the generation service provider;

d. Content propagation service provider: name or code of the service provider; and

e. Content propagation ID: unique content ID assigned by the content propagation service provider.

(2) The format of implicit labels added into file metadata must comply with the requirements specified in Appendix E.zip. For more information, please refer to the Labeling Method for Content Generated by Artificial Intelligence and the Notice on Releasing Six Cybersecurity Standard Practice Guides, Including "Labeling Method for Content Generated by Artificial Intelligence—Implicit Labels in File Metadata—Text Files".

(3) Only one implicit label shall be retained in the metadata of each AI-generated content file.

8. Why must materials related to the labeling of content generated by AI be submitted?

According to Article 7 of the Labeling Measures for Content Generated by Artificial Intelligence, when releasing an app or reviewing its eligibility for release, the Internet app distribution platform shall require the Internet app service provider to declare whether AI-generated content services are offered. If such services are provided, the Internet app distribution platform is obligated to verify the materials related to the labeling of the AI-generated content.

9. What are the required documents related to the labeling of content generated by AI?

(1) Statement on implicit labels in file metadata. For the template, see the Statement on Implicit Labels in Metadata of AI-Generated Content Files.zip;

(2) Screenshots showing that explicit labels have been added to the AI-generated content in the app; and

(3) Screenshots showing that implicit labels have been added to the file metadata of the AI-generated content in the app.
