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

On 24 June 2025, the National Cybersecurity Standardisation Technical Committee of China (TC260) opened a public consultation on the Cybersecurity Standard Practice Guide – Artificial Intelligence Generated Synthetic Content Identification Methods: File Metadata Implicit Identification for Audio Files until 6 July 2025. The consultation focuses on the draft technical guide, which is based on the mandatory national standard GB 45438-2025 Cybersecurity Technology—Identification Methods for AI-Generated Synthetic Content. The guide provides technical guidance for embedding metadata in audio files, including formats such as WAV, MP3, OGG, FLAC, and M4A, to identify AI-generated or synthetic content. It outlines native embedded metadata and XMP-based metadata schemes with implementation methods. The consultation invited stakeholders, including AI audio content service providers and network information disseminators, to submit feedback.
