Flash-Based CAPTCHA

[BLiZZaRD]

Just go to your "Dummy Layer" first frame and add:

stop();

to the Actions Panel. The sound will then only play once.

Why is Flash being used for this? :-\

BLiZZaRD, for reference, PHP can be used to generate Flash. The Ming library exists for exactly that purpose.

[BLiZZaRD]

Hmm... I will have to look into that.

I don't often dwell in the Flash/php things very often. Just the high scroe list here and there

Basically, just experimentation. But I'd like to see a CAPTCHA system with images as well.

If I were you, I'd do that server-side too. Doing it with Flash would put some serious strain on the user's computer (and also deny access to people without serverside scripting support). Also, Flash is on the client, so the bots can simply extract the string used to create the CAPTCHA.

Ok. So how would I do that server-side (using PHP)?

[BLiZZaRD]

Working on an example, give me a bit of time

[tech_support]

No prob.

Well, I finally got a free minute.

It isn't pretty, just giving some examples, but I made a Flash CAPTCHA.

Right now it loads 1 of 5 random numerical and 1 of 5 random alphabetical strings from an array into a textbox that is "blocked" by a design.

You enter the letters you see in the empty text box and click the button.

If the alpha numeric code matches it tells you it matches, if they don't match it resets and gives you a new string.

And if you just click the button it prompts you to enter the code.

Not bad really, if I do say so myself.

I could probably add the audio too, if I was positive on how you wanted that to work along with the strings.

I was kinda looking for something like this: http://www.xpanel.com/images/check_f...215&cval=4kg8d

You see the "cval=4kg8d"?

If you click on the link, it'll show 4kg8d.

It uses JavaScript for the rest.
