Flash-Based CAPTCHA

[tech_support]

Not so. The virtual machine is on the client; therefore, if the client really wants, it can read any and every variable and value used in the "movie."

Client-side CAPTCHAs are not secure. No, not even if they are in a compiled language.

Meh. I can't spend 3 days working on a CAPTCHA system that fools the bots. What if the user signs up and advertises? I'll just ban.

So... how can I do this?

It's a little more secure than I think you are giving it credit for.

It's certainly slightly secure; the elaborate scheme you created would probably fool most non-specific bots. However, a bot built specifically to spam on your site would have no problem getting through it. This just all seems very pointless to me, especially when it's so much easier to do serverside.

How would you de-compile a compiled flash program?

With a Flash decompiler

I remember asking for that before...

But I'd like to see a CAPTCHA system with images as well.

What type of images?

Tell me exactly how you want the CAPTCHA system to operate, what it should have, what it is preventing sign ups for (i.e. email, to view a page, send a contact form, etc) and what you want it to entail.

I will build you an example, and if you like it we can then move on to better graphics and functionality, if you like

A CAPTCHA to prevent automated registration.

Here's an image that I like:

Okay, but you mentioned audio too, so what do you want to do with that?

[tech_support]

Just a little "Play" button would do.

Are we still talking Flash here? Anyone with a screenreader will be unable to view this anyway...

[tech_support]

I'd like to see both Flash and Graphics.
