captcha with voice

ashley98860615

I have been making a captcha verification thing and everything so far works. however i would like to add voice. I thought it would be a simple matter of returning an array of links to files with the image but i can't figure it out. Then i tried using a session and realised the potential security risk.

any ideas?

i'm creating my image using gd and calling it from <img src='verification.php'>

here you go: Audio & Visual CAPTCHA

Looks like a CAPTCHA that would be easily broken with the image, unless you plan to use the audio only.

I like Bokehman's solution: http://bokehman.com/captcha_verification

(looks like he is updating his site currently, so you may be better off checking tomorrow, LOL)

But seriously, his script is really nice so ...

In some of the examples i have found the captcha session code isn't md5'ed before it's stored, doesn't this pose a security risk? However, it seems this is the only way to pass the data correctly between the image and audio functions

never mind, didn't think of md5ing it after it has been passed with the audio page
