What about using a static effect in the background, but a still static in the foreground? Gif related. If computers can only analyze individual frames, then they can't see the letter.

I call it Static Static-Static.

Also I threw this at Uncensored.AI, it thought it was Captain Kirk being shot. I threw it at ChatGPT, it couldn't figure it out at all. Since it is impossible to screenshot the image without losing the text, it completely fucks up image analysis because it just sees the noise.

>>108103959
Easy cracked

Just capture 2 frames and diff them against each other

Frame1.pixels - Frame2.pixels
Keep diff values < 5
Run more frames for better accuracy

Run OCR on that diff-image, get text

Pro tip: your brain already does this

This is true but how many spambots are actually going to go to that much effort? It's already more steps than "Type XPLDN0"

Take the average of say 20 frames.
The noise cancels itself out to form a smooth gray whilst the message remains undiluted

I like the idea, but has a big flaw.
It can't be detected using conventional AI but it can be automated by an easy filter.

My idea for better captcha has always been IQ test questions with an invisible timer. Even if you get the question right, it still won't let you post if you don't answer in an appropriate amount of time. The intended effect would be to filter Indians, spam and retards.

>>108106424

Computers can definitely analyze multiple frames, and yes llms can too (provided they have enough context length).

You dont even need an LLM though. All you would need to do to get the letter from that gif is dif two or more frames together and get the pixels that don't change, set everything that didn't change to black, then run OCR on it (which has been done for decades and doesn't need to be AI).

Letter based captchas are all equally useless, that's why basically nobody uses them anymore.

The captcha should contain extreme pornographic content so most LLMs will censor themselves and fail the captcha.

Any captcha can be solved, it just takes time and effort. If you put this captcha on 4chen someone will make a script that averages the frames or whatever so they can solve it. I don't think this one would be particularly hard. Once they have a solver they can simply update their spam bots and continue. The same thing happens with every captcha, that's why they make new ones.

By virtue of the gif containing the necessary information to parse the message, a computer can parse still it. It's just slightly harder.
At this point I wonder what's the point in using captchas at all.
>>
>>108109725
At some point it would be easier to replace the captcha with a filter that requires you to include something like “niggers” or “heil Hitler” in your post. If nothing else it would block the troons until they can get a shabbos jeet to fill out the captchas for them
>>
>>108107521
>>108109725
It cannot be detected by an AI but it can still be automated.
If the background static noise is flowing in one direction and the text static noise is flowing in a different direction, we can detect the area of the background at column 1 (or row 1) on the first frame and compare it to the area of column 2 (or row 2) on the second frame, rinse and repeat for all of the rows, then do it 4 or 5 times more but with an offset of -1 each time to get more accuracy:
First batch: col1 at frame1 for all columns.
Second batch: col1 at frame2 for all cols.
Third batch: col1 at frame3 for all cols.
And so on.
Then compare all the batches with a simple logic gate operation and then you have the text. Run OCR and submit the captcha.

>>108109868
You're right, but you're assuming the pixels are always moving column to column. I think a bot developer should attempt to generalize in case the captcha gets more complicated.
Assuming all pixels of one layer are always moving in the same direction, you could probably do a similar algorithm but instead of columns it's patches of the image and you're trying to find the direction the patch is moving into by finding the best nearby match for it in e.g. the next frame.
Assuming all pixels of background layer A move consistently, it won't be difficult to notice when a patch of layer A passes under foreground layer B, and where they intersect by checking which parts of the patch that were consistent before have now become inconsistent.
>It cannot be detected by an AI
This sounds wrong though. Through machine learning you should be able to parse these gifs, they aren't that complex.

It's trivial for an AI agent to generate a diff between two frames and look at the result.
The Turing test was obliterated. There's no reliable way to tell AI agents from humans anymore. It's all a matter of implementation.

There is no need. There are only 4 directions pixels can move. It is much more efficient to bruteforce all 4 tries, you'll get the result anyway.

>Through machine learning
Building a model just for this is total waste of resources and time.
You also need a large number of gifs, more than 1000 (which needs to be created by the captcha, you can't made them yourself), and each one needs a correct solution for each gif.
And remember that each time the captcha is updated, the model becomes useless.

It's interesting how it's easier to discern the moving noise compared to the non-noise.
You could still do the diffference trick. Just have each pixel store how many of it's neighbours (both spatially and temporally) flipped colour. The black sections will have high difference and the white ones low.
