Advanced Captcha Image

Post by ziggy3000 »

i need a captcha that works and looks like this one

if you could have it used in an example, that would be great! :D

the captcha doesn't have to look like that, but i want it to look web 2.0

Yeah, you've tried your hand at creating a 20 page thread on creating a syntax highlighter, why not this too? :P

What exactly is one supposed to find in that image? I don't see any text/characters, so the number of lines in the image?
Edit: Or is it missing text becuase nothing was passed to the script? Doh!

Hehe, it's a thought. I've made a few captchas in my day, but you could always just download a pre-made one. Captcha's aren't very difficult to make, but adding all of that extra graphical stuff takes time (and math).

well, i have good news. i have learned enough php to make the exact same captcha image!
well, it's close. i just need help rotating each alphanumeric digit and putting it in a random spot, yet, you can still read it.
and the font seems a little different.
and there's not as many lines, but still works :D

Rather than messing with GD to make the graphical image (which is probably the best idea) you could just make X amount of captcha backgrounds and rotate them in randomly.
Set Search Time - A google chrome extension. When you search only results from the past year (or set time period) are displayed. Helps tremendously when using new technologies to avoid outdated results.

I just made a pretty good Captcha. Right now I'm working on understanding and deciphering some more advanced distortion techniques.

You can rotate text straight through GD if you use custom fonts (which you realllly should).

In my opinion, if one is going to implement a CAPTCHA image generator, he should begin with understanding various and plenty techniques for image recognition, especially OCR. I have a friend who *was* working for a company which develops antiCAPTCHA software for other SPAM companies. ;) They even developed a voice recognition software for SPAMing forums with accessibility features.

So - I don't think it is an easy job to do ...
There are 10 types of people in this world, those who understand binary and those who don't
