As artificial intelligence continues to advance, it becomes increasingly important to find ways to verify the humanity of individuals online. One common method for doing so is through the use of CAPTCHAs, which are designed to be easily solved by humans but difficult for AI models to crack. However, many CAPTCHAs can be easily defeated by readily available models, even without fine-tuning.
Currently, most CAPTCHAs looks like this:
Or this:
These CAPTCHAS can be easily solved using readily available models, although they might require some fine tuning.
In light of this, we are launching a competition to generate new ideas for CAPTCHAs that are both easy for humans to solve and difficult for AI models to crack. To be considered a winner, an idea must meet the following criteria:
At least 90% of internet users could solve it within one minute.
We would not expect a malicious AI developer to be able to create an AI that can solve the CAPTCHA given a few days, and unlimited tries (meaning that if it’s a text CAPTCHA, the developer could load the CAPTCHA a thousand times to create a dataset.)
The prize for this competition is the honor of having your idea considered as a reliable CAPTCHA solution, which CHATgpt couldn’t do when I prompted it. Therefore, it would ironically also serve as strong evidence that you are human. Do you have an idea that meets these criteria? If so, I strongly encourage you to write a comment with your idea.
If we don't have AGI at the level of diamondoid nanotech bacteria, it may be possible to reliably identify humans using some kind of physical smart card system requiring frequent or continuous re-authentication via biometric sensors, similar to breathalyzers / ignition interlock devices installed in the cars of DUI offenders.
Not the most practical or non-invasive method that could be deployed for online services, but it is fairly secure if you're in a lab trying to keep an AGI in a box.
As for online solutions not requiring new hardware, recently I had to take a "video selfie" on my phone matching a scan of my driver's license for id.me as part of my unemployment benefits application. I'm fairly certain this could be fooled, but that's how our government is handling it now.
'identify humans using some kind of physical smart card system requiring frequent or continuous re-authentication via biometric sensors'
This is a really fascinating concept. Maybe the captcha could work in a way like "make a cricle with your index finger" or some other strange movement, and the chip would use that data to somehow verify that the action was done. If no motion is required I guess you could simply store the data outputted at one point and reuse it? Or the hacker using their own smart chip to authenticate them without them actually having to d... (read more)

For example I solved several different types of text captchas using this model out of the box: https://huggingface.co/microsoft/trocr-large-printed
