So.. yeah, the bottom line here is that the font has to render from something.

In this case, it's rendering from a hidden input element:

Gee.. yeah, that's entirely indecipherable.

If you want to erect security between AI and content, then ...

yeah, just don't bother. It's not even worth the trouble and it's quite likely impossible at scale anyway.

What is making it hard to read for so many people? My eyes aren't young or healthy, but it is as clear as day for me. Wonder with screens play are role.

I tried with my phone vertical and couldn’t see anything. In horizontal ie bigger image it was clear as day. I think a lot of the variance is probably screens.

Earlier quoted context omitted.

It’s been years since captcha was contributing to labeling.

Indeed, they don't contribute to labeling. The self driving companies figured out long ago that machine learning is way too expensive. Instead, Google is using its large network of willing humans to inform automated driving decisions in real time. So the next time you're asked to click the pictures with the bicycles or traffic lights? Please do so before it's too late. (/s, if that's necessary)

> For example, it would be interesting to incorporate Ghost Font into CAPTCHA systems, as most systems are easily solved by AI today. It seems to me like it should be easy enough to take Ghost Font, apply normal video compression techniques, and analyze the compressed signal to recover the visual outline of the letters, which you would then analyze with OCR (or an AI I guess ...). In other words, a novel CAPTCHA tech…

I took just two screenshots and applied some filters and got https://fingswotidun.com/images/GhostFont_2_samples.jpg https://fingswotidun.com/images/GhostFont_b_2_samples.jpg An AI would be able to take consecutive frames rather than hamfistedly pressing the screenshot button, then accumulate enough samples to clearly make out the text from a clip shorter than the time it would take for a human to read it.

"Written in ghost font" is the decoy message. Your filters got those words.

The real message is "only a human can read this" and your filters didn't get these words.

(But I think there should be a way to catch them)
