Duale AI's implementation of C2PA text marking (C2PA 2.4 Annex A.8)
Hide a site domain inside a visible name using invisible, passphrase-keyed Unicode. If the name leaks, find out which site leaked it. Single self-contained HTML file, no dependencies.
📜 给任意文字加隐形水印：Unicode 变体选择符隐形层（Reed-Solomon 纠错 + 可选 AES-GCM-256）+ AI 可读 emoji 签名条。纯浏览器本地运行，无服务器 / 无构建 / 零网络请求，编码规范完全公开。Post-hoc invisible text watermarking — 100% client-side, zero network requests, fully public spec.
