As in all of my examples that does not quite reflect reality. They produce way more than that.

Reality is sneaking in?

on a 2TB harddrive i can store ~140Mio. Captchakeys

if with compression there are much more

but it seems that nobody wants to help/work with me... but i hope

Because theoretically it's a pure nonsense... The problem is, that the words can be the same, but deformation can be different, the word can be on the other side or the case of the letters can differ. And it's statted on the recaptcha site, that it can be hardened if needed. Even if you use only half of the image and then half of the size, it's about 2^1800 of possible images (for b&w image).

I think that the control word is always easily readable and so probably recognizable with NN or some other tool. So you need 1.detect, which one it is,2.try to recognize

aj, ive told you. If you want to set up a db you can automatically do it, it be quicker than people entering the data in their spare time. But like i said it is totally pointless because the words change the ocr software is updated every day so its a new word a little different with mistakes if there is one. Its on there site that the captcha's are created from scanning in books to make the digital new books added every minute!

This is complete another way. This is a network of people, they solved captcha by hand. Nothing automatic.
