    Decoy Font: A TTF font that hides what you type

    Decoy Font combines every letter with a decoy, making it harder for AI to read what you type. Type a message to try it out or download the TTF directly.

                In selection 2, you don’t seem to be selecting an image. You’re selecting text.

                In method 1, it’s doing OCR. In method 2, its just reading the raw text data you selected. This is how you can copy text from thing A and Font A, and paste it into thing B with font B (depending on Thing B’s paste settings)

                Nice ! I didn’t think the font had a serious purpose before I saw your excellent example…

                  Here’s the text my phone extracted from that image:

                  FUCK THE POUXCE

                  What does this say?

                  It says “THIN BLUE LINE.”

                  The word BLUE is split between the second and third lines:

                  THIN

                  BLU

                      It works at full resolution, but it’s a cat and mouse game. If something like this becomes popular, then all that needs to be done is to start passing images through a filter first (blur, lower resolution, etc.), or just train a new vision model that can pick out both the blurred message as well as the decoy message.

                          The downloadable font is especially vulnerable since each letter is a straight map, so easily trainable

                          Well, I’m glad that we now have a font that makes it look like I’m not wearing my glasses… when I’m wearing my glasses.

                                  Screen readers read text directly, the point of this is to be used in images, which screen readers don’t read anyway.

                                      Facedeer is a bad faith troll and AI evangelist, in case anybody is wondering why he’s pretending to care about accessibility.

                                              By “bad faith troll and AI evangelist” XLE means “someone I disagree with about this topic, and therefore that I follow around obsessively accusing of being a troll.”

                                              He’s really rather sad that way, I notice that every thread I’ve been in over the past few days with any relation to AI he’s been adding this comment to. Guess he noticed me again. At least he’s stopped calling me a literal bot or accusing me of being “from Reddit” as if that meant something nefarious.

                                            My iPhone reads text from images. I wonder how it’d do with this?

                                                You can take a screenshot or save the image directly. My iPhone reads the blurry text without issue, so this may be more related to LLMs in particular, or of the image is compressed before the analysis, the illusion is broken

                                                    Amazon Rekgnition struggles a little more but it’s still reading the blurry text instead of the lines

                                                  And if this sort of font became common (and actually kept working) then screen readers never would be able to read these. The point remains that accessibility is being sacrificed for the sake of some kind of general “anti-AI” movement.

                                                      There’s no way this will become common. Non-visually impaired people don’t want to read like that either.

                                                          Back when generative image AIs first came into general awareness with Dalle-3 and Stable Diffusion and so forth, there was a fad of changing image alt text into deliberately misleading nonsense. Which, of course, was not great for the visually impaired back then either. It was ineffective and short lived, but it’s still pretty annoying seeing people proudly declaring their intent to make things deliberately difficult for people who rely on technology for this kind of stuff. So IMO worth pointing out.

                                                      Most AI systems work by reading the pixels of an image up close

                                                      In the case of text aren’t LLM’s reading actual text ?Whats the usecase here ? For any text I dont want to be readable by ai scrapers and such, I need to use this font and render as image(s)?

                                                          This is not for the case of using text, it’s for protecting text in images. The problem with adding invisible text is that LLMs can defeat it by screenshotting and using OCR. This tries to plug that loophole.

                                                              Invisible text doesn’t work for images though, which is what this is specific for. Invisible text is also defeated by taking a screenshot, so if you use this too then you have a chance of defeating both LLMs that read the text as well as those that screenshot and OCR.
