Are there any real programmers on GFY or just a bunch of wannabe kids?
 

Can you beat this:

no , those cant be beaten

Good luck :)

What am I looking for? :helpme

that will be tough.......

They can, and they have been beaten with up to 93% success, I've read articles on the Internet, and if its on the Internet it must be true ;)

Everything can be beaten. It just takes time and money.

for the ladies

the captcha system as is used in that scenario is alot harder to "read" programatically... while considerd impossible even by myself; i do think it would be doable with the right algorithmes... the main issue for a system like that would be the computation time... a standard captcha system isvery crackable and can be broken down in a matter of seconds (0.7 seconds is the fastest i have gotten it on a simplistic distortion)...some thing like the ones you are showing have advanced distortion applied and the false-positive ratio can/would go to hell in a hand basket...

anyhow what i am getting to;it can be done but the time the computer would spend attempting to decipher it could actually become slower than a human...

contact me on icq...

oh and in regards to real programmers vs wanna be kids...

i've been programming for the 14 years; i have worked with fortne 100, 500's; global 100's; government agencies... i've got experience with more programming languages than i have fingers and toes... i'm far from a wannabe; so hope that answers your question...

While it may be extremely difficult, anything mathematical is solvable. The program that creates the graphic is based on math, and the program to try and read it would be based on math. It's just a matter of the right formula. While an average programmer might have a hard time with it, a programmer working with the right mathematical brain could do it.

So basically I'm better off hiring a $20.00/day to do whatever I'm trying to do?

$20.00/day = $20.00/day guy

yeah do it.

while mostly true there is one thing that should be mentioned... the idea behind the captcha system is a standard turing test; a method to differentiate from human intelligence and artificial intelligence...the main difference is the use of optics for decoding it... even in a simple captcha system like the one fl_prn_str posted; requires more than mathematics to crack it (i know, i've done it)... while mathematics is the bulk of it there is a need to emulate the optical part of the system, therefor integrating an advanced OCR type system... the main issue is the flexibility that the human brain has when linked with our eyes and the more strict guidelines that a computer program would have to follow...

in the end, yes the one displayed by antonio (a sample captcha from a hotmail signup i presume) is far more complicated than the one fl_prn_str displayed (craigslist example), yet it can eventually be cracked with the write programming... just as a note though, the hotmail one has to be the most complicated one i've seen with very simple modifications... even the aim and yahoo captcha systems would be easier and have a higher hit ratio than the hotmail one...

The key is that this doesn't have to work 90%, 50% or even 25% of the time. If the algorithm decodes it only 10% of the time, and if for example hotmail gives you 5 tries before banning your ip. You only need on average 2 proxies for each signup.

And getting it work 10% of the time is quite doable given enough time and $$$.

obviously a failsafe would always be built in to something like this; however if it's any less than 75% positive it's quite useless... working proxies are not easy to come by anymore; plus they add in a certain level of delay; and in the event of 10% as you suggested you would most likely need alot more proxies than 2... 10 tries does not equal 10% ;)

personally i wouldn't be satisified unless the system was 95% efficient...

I find a lot of these are so ridiculous it takes me 3-4 tries to actually enter it properly myself.

If it does the job (to signup for hotmail accounts for example) it's far from useless. Delay doesn't make any difference, you could just start a seperate thread for each signup. And true that more than 2 proxies may be needed, but I was just trying to illustrate a point that the program can be successful with hit rate of under 50%.

ding ding ding, we have the correct answer :)

well, there's nothing on that website, and google tells me that there used to be some SE tools, so I'm niot sure how does that relate to this thread?

i still disagree; in a realistic scenario your percentages of testing should be based off of at least a 1000 samples... this is to account for severe distortion variations (this obviously has to do with the mathematics), the possiblity of hitting all used characters, etc... now if in such a test environment you manage to achieve 99.7% success, a real world application will easily jump down to a 90% (perhaps even 80%) success rating since you have heavily skewed the probability at that point; not to mention any application you devevlop will be geared at solving those 1000 samples as good as possible...

now if we were to take the same scenario of 1000 samples and even a 50% success rating, you are going to have some problems... so if you only have 5 chances to hit the correct target; your percentage no longer remains 50% success since your pool of data has dramatically decresed... in reality your success rating drops to a mear 12.5% (of the total 5 tries, not each individual guess) because of the odds you had before...

even if you have the time to wait for it to hit (let's say an 8 hour period while you are sleeping) you are not going to have alot of those processes go through...

the bottom line, imho, is that this would require a program that has been well tested and has a very high success rating in the sample environment... a program like this would take time as well as cost a nice ammount; well worth it if the revenue generated from it exceeds the development cost; otherwise as stated in this thread as well as to antonio in icq; it's better to go with the hired hand since it won't be profitable enough for him to make an investment for a program like this...

theres programs that can identify fingerprints off any surface, no reason this couldnt be doable with enough programming

ive done a few, nothing that complex (yet).. but its definately something i plan on playing with in the future :)

That's because you're the greatest programmer in the world!!!! <333333 :)

So Childesh, Use Your Brains
 

hehe all you childesh minds, it's very simply how to defeat those things, create an animated gif and make the first frame blank or better yet a BOGUS word :)

Do you know what I love about some of the images like you have here at the top of the thread is that even humans can't read them... they try a couple of times to get it right... Then they leave your fucking site... Great job running people off!!! You rock!

here is my example (done very quickly) shown here

http://www.megapussy.com/webmasters/beginocr.php

now right click over the image and hit copy or whatever, now
take that to your paint program and paste...

what do you see? :)

Whjen i was taking submits from everyone on TGP, the results
were halirious, All the scammers that post those TGP pages with the virus
and pop up hell's that were submitting starting emailing me... All I get is a
blank gif for the submit code...Man that was so funny when that happened....

Seems their autosubmit OCR cheater script came to site
took a snapshop of the code for them to just sit there and type it in
since the script can only copy the first frame of the animated gif they
got a black image.... theyre tools became worthless..

1st one - Hotmail
2nd one - Yahoo

I have no idea what are you talking about.

it;s not related, i'm feeding se spiders. :-)

Lol, you really got me puzzled with that link ;)

I don't get it. :1orglaugh

dumb
 

poster needs to be more clear what the he is talking about, I guess i misinterpreted thread.

Basically i think he is trying to act like he has some sort of skill in something

yes any code can be beaten. any..

it just takes time and wil power

If a service had a Captcha like this I wouldnt use that service.

this is fucking easy to beat
teksonline's is harder, but still possible ;)

personally I would just pay some indians to do that...

Antonio I dont know or care what you've read I just know first hand those cannot be beaten.

No point. (If) you beat that, they will come up with a more difficult pattern the same day. Waste of resources.. better utilize the them for legal endeavors, you'll make much more money.
