China: TC260 closed consultation on Guidelines on Identification Methods for AI-Generated Synthetic Audio Content

On 6 July 2025, the National Cybersecurity Standardisation Technical Committee of China (TC260) closed its public consultation on the Cybersecurity Standard Practice Guide – Artificial Intelligence Generated Synthetic Content Identification Methods: File Metadata Implicit Identification for Audio Files. The consultation sought input on metadata embedding techniques for AI-generated audio in formats such as WAV, MP3, OGG, FLAC, and M4A, covering native and XMP-based approaches. The draft aligns with mandatory national standard GB 45438-2025 and aims to standardise implicit identification practices for AI-generated content. Submitted feedback will inform revisions before finalisation.
