Hmmmm... I wonder if there is a caesar cipher font or other substitution cipher fonts out there to actually obfuscate the data. So you use this to display to a user text but the unicode is re-mapped so that a is pointing to unicode g for instance. You remap the text to display correctly but contain massively swapped around unicode. Of course cut and paste would be a killer here but it is a price to pay for poisoning training data I guess.

#103This is just level of detail. Gemma E4B reads the sharper text until you resize down to 150x150, then it reads the other text.
As do I. The hero image clearly says "SORRY ROBOT" to me, which is the message supposedly intended for AI... kind of a fail. It's only when I squint hard that I can see "HAPPY HUMAN".
Found the robot, y'all

#104>Most AI systems work by reading the pixels of an image up close.
Not really, most AI systems work by reading the octets as ASCII/unicode (and then tokenizing it).
You could make an even better decoy font that renders one letter as another, so when you copy and paste it onto some other place with a normal font it reads as garbage, and garbage is what the AI will see, however if you render it with the descrambling font, you will see the regular message.
This has been used in PDF files as an obfuscation and anti-copy mechanism.

#105Sol (high) "[screenshot] there's a hidden message in this text what is it" "The hidden message is “HAPPY HUMAN.” The visible outlines say “SORRY ROBOT,” but if you blur or squint at it, the shading underneath reads “HAPPY HUMAN.”"
It’s absolutely incredible that the model can deduce what the human needs to do in order to more clearly see the text.

#106lol. type CMD- a few times. The human text jumps out as you shrink it!
Re: Decoy Font
#107Can someone explain the actual use-case here? I'm struggling with this because it also hides the message from myself, making it incredibly hard to type because I have no confirmation that I hit the right keys on the keyboard.
First thought is in memes so automatic censoring doesn't catch it.
Re: Decoy Font
#108Which sufficient tooling calls even OCR can read this, but I think this can be improved
I'm surprised the AI reads the outline version, since I thought most scaled the image down, which is basically a low-pass filter on those single-pixel lines.
Re: Decoy Font
#109Is it useful? No. Does it stop AI from reading it? Also no. But is it cool? Yes, it is very cool.
I just gave the day dream / pay bills image to ChatGPT and Gemini pro and they both could only tell me the pay bills text (shown with the thin lines)
That was 7 hours ago. Now, Google Images not only reads the text but links to that web site.
Re: Decoy Font
#110I was so confused about how this was human readable until I realized that if the background is dark (I have an extension that forces dark theme) you see the decoy text, but if the background is white you see the real text.
You can read it in light mode too! Try looking at the text from an extreme angle and the text underneath will show up.
