Can AI Watermarks Speak Every Language? A Simple Trick
Ever wondered if a hidden signature in AI‑generated text can survive a trip across languages? Scientists discovered that today’s multilingual watermarking often vanishes when a text is translated into medium‑ or low‑resource languages—like a secret ink that fades on cheap paper.
The problem? The AI’s “vocabulary” doesn’t have enough whole‑word pieces for many tongues, so the watermark’s meaning gets lost in translation.
Imagine trying to spot a tiny logo on a poster after it’s been photocopied many times; the details blur and disappear.
The new solution, called STEAM, flips the script by translating the text back to its original language first, then checking for the hidden mark.
This clever back‑translation step restores the signal, making the watermark robust no matter which language you use.
It works with any existing watermark method, needs no changes to the AI, and can be added to new languages with ease.
Now AI can leave a reliable, multilingual fingerprint, helping us track content responsibly and keep the digital world fair for everyone.
