Watermarking Without Standards Is Not AI Governance
This position paper argues that current AI watermarking efforts risk becoming mere symbolic compliance due to a misalignment between regulatory expectations and technical limitations, and proposes a three-layer framework of standards, audit infrastructure, and enforcement to ensure effective governance.

The Big Idea: A Broken Promise
Imagine the government tells all the bakeries in town, "You must put a special, invisible stamp on every loaf of bread you bake so people know it's real and not made by a robot." This is what AI Watermarking is supposed to be: a hidden signature in AI-generated text, images, or audio that proves, "Hey, a computer made this."
The paper argues that right now, the government is asking for these stamps, but the bakers (AI companies) are putting on fake stamps or stamps that wash off in the rain. Because there are no strict rules on how the stamp must be made or who gets to check it, the whole system is just a "box-checking exercise." It looks like safety, but it doesn't actually protect us.
The authors say: Without strict standards and independent inspectors, watermarking is not real governance; it's just a symbol.
The Three Big Problems (The "Why It's Failing" Section)
The paper identifies three main reasons why current watermarking isn't working:
1. The "Strong Enough" Mystery
The Problem: Laws say watermarks must be "robust" (hard to remove), but they don't define what "robust" means.
The Analogy: Imagine a law says, "Your car brakes must be strong enough to stop the car." But it doesn't say how fast the car can be going or how far it needs to stop.
- If a car stops in 10 feet from 5 mph, is that "strong enough"?
- If a car stops in 100 feet from 60 mph, is that "strong enough"?
In the Paper: AI companies claim their watermarks are "robust," but if you just change a few words in a sentence or add a little static to an audio file, the watermark disappears. Because there's no standard test (like a crash test), companies can claim they are compliant even when their watermarks are weak.
2. The "Black Box" Detective
The Problem: Governments want independent experts (like researchers or regulators) to be able to check if a piece of content has a watermark. But currently, only the AI company knows how to check.
The Analogy: Imagine a bank says, "We have a special lock on our vault." But they refuse to show the key to the police or the auditors. They just say, "Trust us, the lock is there."
In the Paper: To check a watermark, you often need a secret key or a specific tool that only the company (like Google or Meta) has. If they don't share the tool, no one can verify if the watermark is actually there or if it's just a lie.
3. The "Voluntary" Trap
The Problem: Governments are hoping AI companies will voluntarily do the right thing.
The Analogy: Imagine a neighborhood where the HOA asks everyone to pick up their dog poop. They hope everyone does it because it's the "nice thing to do." But if you don't, there's no fine.
In the Paper: Companies know that making a really strong, unbreakable watermark is expensive and risky. If they make it too strong, hackers might figure out how to break it. If they make it too weak, they save money. Without a law forcing them to do it, they will choose the "cheap and weak" option just to say they tried.
The Solution: The Three-Layer Cake
The authors propose a new system to fix this, which they call a Three-Layer Framework. Think of it like building a secure house:
Layer 1: The Blueprint (Technical Standards)
- What it is: We need a universal rulebook for how to make the stamp.
- The Analogy: Instead of saying "make a strong lock," we say, "The lock must survive being dropped from a 10-foot ladder, soaked in water, and hit with a hammer."
- How it works: We need a shared library of tests. If an AI company wants to sell their product, they have to run their watermark through these standard tests (e.g., "Does the watermark survive if I summarize the text?"). If it fails the test, it doesn't get a license.
Layer 2: The Inspector (Audit Infrastructure)
- What it is: We need independent people to check the work.
- The Analogy: You don't just trust the builder to say the house is safe. You hire a third-party inspector who has a checklist.
- How it works: Independent labs (not the AI companies themselves) would test the watermarks. They would use "black box" testing (they don't need to see the secret code, they just test the output). If the system passes, they give it a "Certified Safe" seal.
Layer 3: The Police (Enforcement)
- What it is: Real consequences for lying or failing.
- The Analogy: If the builder lies about the lock, or if the inspector says it's broken, the builder gets fined or can't sell the house.
- How it works: If a company claims their AI is safe but fails the audit, they face fines or are banned from selling in certain areas (like schools or hospitals). This makes it too expensive for them to cut corners.
Why This Matters
The paper concludes that if we don't fix this, watermarking will become a "security theater."
It's like an airport security line where everyone puts their shoes in a bin, but the scanners are broken. Everyone looks like they are being safe, but a bad actor could easily slip a weapon through.
The Takeaway:
To actually govern AI and stop misinformation, we can't just ask companies to "try their best." We need:
- Clear rules on how strong the watermarks must be.
- Independent inspectors to check the work.
- Real penalties for companies that fake it.
Without these three things, AI governance is just a suggestion, not a law.
