gif captcha Nanonymous No.8865 [D][S][L][A][C] >>8922
maybe it's a stupid idea, but would it be possible to implement a captcha with a gif?
basically a gif image with randoms letters but they appear and disappear and have some other distortions that change with time, done in a way that it loops

would it be harder to crack? is it anti-user or pro-user? is it too much slow to make gifs on server?

Nanonymous No.8866 [D] >>8868
That would definitially would make it more difficult to do and OCR on the captcha, but only if it is animated in a way that makes it hard to tell when transistion from one letter to another is finished.

what happened to the stupid questions/questions that don't deserve their own thread ?

Nanonymous No.8868 [D] >>8921
>>8866 (observed and noted)
you could do lot of stuff with the gif animation, for example you could move the letters around, making change color to them, make them change sizes
also you don't need to show one letter at a time, you can show like three toghever and then other three for example

it's more like a stupid idea that i wanted to share, not really a question, even if i phrased it as a question to generate discussion

brb going to register patent on this and steal the idea

go ahead ^_^ but before be a good boy and make a version in lua for nanochan, seems like the hapa nigger broke the captcha today

Difficult CAPTCHA is almost insolvable not only for computers but also humans!

anti-user
simply displaing one letter at a time, as previous morons have tried, does not make it any harder to crack at all. nor does flasing the entire image. both of those only make it more annoying for the user.
the only way would be go full in and make something that only becomes coherent through aspects of the human vision system similar to the temporal integration system. and who knows it still might be complete shit

you don't have to show only one letter at a time
you can show a captcha like the one we currently have but make the image shake and move around randomly to make it more difficult for ai

>make the image shake and move around randomly to make it more difficult for ai
This makes it harder for humans, and no harder for ai. AI can pause the gif, and compare different frames at the same time, while humans can't.

Just a reminder that a gif can be split up into a set of individual frames so it may not be as difficult to crack as you think.

it's called an algorithm

presumably the characters would morph as they move, otherwise the crap would be completely useless (whereas with morphing it would be only possibly useless)
