Breaking CAPTCHA

Yes, if you break a CAPTCHA and it is against the site regulations to do so you commit a crime.

CAPTCHA is there for a reason, to prevent people like you from making bots to do evil stuff. That is the only use I can think of that you would need this for, that had to be top secret.

I'm sure you're not going to find the answer here.

Nobody here has the answer, if they did, they would absolutely have to be some sort of evil spam guy trying to h4xx0r his way past CAPTCHAs, after all, that IS the only reason you could ever want to do such a thing, right? ::)

No, you'd do it for two reasons. For fun, or for education. If you know how to break a CAPTCHA, you can probably devise better CAPTCHAs.

So if I put in my site regulations that all viewers must wear a funny hat, any viewer who wears a normal hat, or even, gasp, doesn't wear any hat at all, is committing a crime?

I think the image processing challenge here is intriguing (as an AI problem), and if anything, will push for better solutions to the problem CAPTCHAs are trying to address in the future. If I had reason or interest, I might "want to do such a thing," but there are plenty of other things I'd rather spend my time doing.

On the other hand, why not try to figure it out yourself? Clearly none of us here have done anything to this level, and those of us who have are only interested in helping you under certain conditions (for example, answering why), so there you ahve it.

if you put it in the terms and conditions that users must agree with then probably yes

Depends on country/state/province/etc, and the sanity of said entity.

Believe it or not, just because you agree to terms and conditions, doesn't actually always mean you have to follow them. In the USA if whatever is deemed unconstitutional, you could get out of it. (Or at least it used to be...)

Speaking of accepting rules on sites, I find it amusing when they use a stupid textarea (for some random reason) and have forgotten/are too lame to make it read-only. I usually delete all the text and "accept" the blank agreement, and then I don't have to follow their rules. :)

And stupid. How is anyone supposed to know that you deleted the text or not? You could be lying!

That's their problem for allowing me to modify the agreement as I wish.

Not that I give a shit about those sites' "TOS" anyway, as they are usually lame.

When I sign contracts I usually put a blank paper over the contract, so that it covers everything but the signature. By doing so I have agreed to nothing! Pretty clever huh? ;)

Kent Larsson: It would be valid if you would somehow be able to physically remove the letters printed on the paper.

The point is that no one except you knows that you erased the contract before clicking accept. And I doubt that it would hold in court even if you could prove it.

Sometimes the license text is in a text file, which you can edit using a text editor. Do you erase the file contents in such cases and then "read it"?

Well... it was basically a joke, but the fact that they DO let you edit it is like saying that you can change stuff in a contract as you wish.

True, but I guess it would only work in theory. :)

It makes it easier to read. Similar to what Kent said, it wouldn't hold up in court. Even if you did prove it.

William - I know it may be used for educational purposes, but I've seen KimmoA in action on IRC and I'd dare say he isnt using it educationally, especially because he won't tell us why he wants to break it.

I doubt that anyone here would like to help you in that case. Even if it would have been for some morally just purpose I would think that you are out of luck in creating something truly automatic (all sites, all captcha types). It's still to much an unknown territory, interesting though.

Well... in this case, it's a specific one that actually is very "static", and should be easy to crack. However, I'm not gonna waste time trying to write my own OCR software. That's on the very bottom of my priority list (although I find it highly interesting).

There's a few things that can go wrong when building a CAPTCHA system, and bad programmers aren't a rarity.
