Help with reading text from a security image.

[Mating_Professor]

can anyone help me out here on making an ocr to read the text?

[Mark__C]

I doubt you'd be able to do it in vb

If you are asking for help on making a OCR I think you are in the wrong place. If you are asking for help on making a OCR (the device) work in a VB program then if you have the OCR you need to try the mfg. web site and see if they have any APIs that you can download. Sometimes, manufactures of devices, do have APIs for downloading. If so, then there would probably be some kind of a guide on how to implement the APIs in your VB program.

Bahh it is possible to make one in vb, I just don't have the know how on how to make one. :) I'll have to go back and ask a professor at my old college i guess.

Well if you know it can be done in VB and you have a college professor that knows how then why you bother to even ask here? 

[r1chard_cran1um]

cause it's more fun to get bitched about here!!!!!!!!!!

[John-]

we should have a bitch thread
whoever makes it has to start it though
and tell us how they feel towards everyone

[baloney_mahoney]

I didn't see the full question at first but now that I have I am sure it cannot be done. I think he is asking about how to read the text in the Yahoo security pictures but the problem is that there is no text to read, it is all picture (pixels) and there is no way to isolate the pixels that make up the word from the rest of the picture.

[r1chard_cran1um]

the bitching was a joke john

if the words are embedded in the photo as the suggestion is, wouldnt he need the key to unlock the words, kinda like pgp or one of them

[baloney_mahoney]

Yes, he would the key. He thought though that the word could be extracted out with OCR logic but he is way off the tract. I don't know how to do it but I have been told that the key is in the name of the picture. Kinda like how your name is embedded within the cookie. 

[r1chard_cran1um]

i kinda thought the key was seperate but dont quote me, im assuming they send the key and then several locations can have access from several persons

[baloney_mahoney]

Well, maybe one way to find out in general is to ask someone who owns a web site (like here or austins or any place) that uses the picture thingy when you need to login and you have to copy the numbers from the picture into the text box. Maybe, but I am not sure, that whatever method is used could be the same method that Yahoo or any place that uses security pictures uses. I just thought that the security word being hidden within the name of the picture was a logical way to do it. When I wrote a little ID maker I went through all the necessary steps to get the ID made and I didnt see anything that Yahoo was sending that I thought could be the key except the name of the picture so I kinda like agreed with the person that said it was in the picture name.      

[r1chard_cran1um]

it very well could be that way, hopefully if it is figured out someone will post results

[baloney_mahoney]

Yep, then ID makers would be fully automatic.

[Mystical]

It wasn't for yahoo's security image and I have done it. I didn't go ask my college professor because he is 150 miles away and thats a long drive to ask him a single question. (I am mating_professor, but i forgot my password agian). My method would be nearly impossible for yahoo's though.

[Mark__C]

no you cant reverse md5, which is probably what they use for the security picture since thats what they use for everything else. even if u knew the key or word.

[baloney_mahoney]

I don't know about this md5 stuff, I am not that involved in Yahoo funny stuff, but I have given up on that damn security picture-word cuz it just aint worth the f---king  trouble.  

[John-]

doesnt john the ripper decrypt MD5?

[Mark__C]

i dont see how

seeing as its impossible

[$-h-ä-W-ñ]

you guys should ask austin.. or limp.. these to act like they know everything about programming.

[aUsTiN]

If Your Gonna Be A Wise Ass, Atleast Explain Your Logic.

[baloney_mahoney]

I'm beginning to think that this MD5 thingy has really nothing to do with the security-word picture on account that I looked further into an old ID maker I had and the MD5 doesn't even play a part in the return data to Yahoo to verify the word. As a matther of fact, when Yahoo sends the security picture to the program the MD5 has a value of 1 (...&.md5=1&.....) and on sending back the security word it has a value of null (&.v=0&.md5=&.ind=...). 

[$-h-ä-W-ñ]

MD5 i saw that somewhere...oh yeah.... i was cracking with matrix reload and a message keep coming up with MD5.. i didn`t know what could it mean.

and yo austin i not trying to be smart ass.. i have asked you about 5 times now why my comp freezes when ever i go to your site?
and you never answer... but hey atleast i got you intention.. with the last post.

[John-]

he answered you in another post, i dont recall where it is but you were using your spliffy username i think.

[John-]

i think this is it, at least i think it is a reply to you but i am not sure, i might be wrong.

oh yes he did.. lol
thanx john..

no problem

Making an ocr is quiet easy, but it was a standard font Still counting/compairing pixels any picture would work on reading it.

Of course. If the font used is the same all the time. But that is not the case nowadays. I would even go so far to say that if several fonts are used it is conceviable but when you get pictures with twisted and distorted letters it would be next to imposible to determine what pixels make up a character and what pixels do not. I guess the point is that if one wants an OCR to try and interrpet the Yahoo security pictures you just aint going to do it, maybe once in awhile, but for the most part no. 

[Mating_Professor]

you can now shut the **** up ok. It's been done there is a website somewhere that even has a program that reads the secret image on yahoo. It's been out for quiet some time and its work something like a 97% of the time.

[baloney_mahoney]

Well, unless you can prove it I suggest that you shut the **** up
