Gate News Report, March 16 — Recently, MacRumors analyst Aaron discovered strings related to AI content detection in the code of the X platform app, including “COMPOSE_VIEW_C2PA_AI_DETECTED_TOAST” (post interface C2PA AI detection toast) and “AI generated content detected.” This indicates that X is developing a feature: when user-generated content is identified as AI-generated, a warning will pop up before posting. The feature is based on the C2PA (Content Authenticity Initiative), an open technical standard for tracking content provenance, initiated by companies like Adobe, Microsoft, Google, and Intel. It embeds encrypted signatures in files to trace content sources and creation tools. Platforms such as LinkedIn, TikTok, and Meta already support the C2PA standard. Currently, X’s own AI tool Grok generates images and videos with watermarks, but it has not yet actively detected content created by third-party AI tools.
