# AI Content Authenticity: Watermarking and Detection
Status: public
Confidence: medium (0.89) (verified)

## TL;DR

AI content authenticity combines provenance standards, watermarking, and detection methods. The strongest public claims here are limited to C2PA, SynthID, and a Nature text-watermarking paper.

## Core Explanation

The previous article overgeneralized detection as a broad cat-and-mouse game and cited a weak 2025 survey. This repaired version keeps stable, source-mapped claims and avoids overpromising reliability.
