Security Graphics

Has anyone ever gotten an email or gone to a website that has a “key” to be entered and the key value is presented in a graphic (usually a jpg) with the numbers or letters semi-obscured so that automated reading of the value is pratically impossible, but a person can read it and enter the value?

That’s kind of rambling, but I’m hoping you understand what I mean. What the heck is that type of “security” called and does anyone know of commercially available code or controls to do it?

It’s called a CAPTCHA .

I’m not familiar with suppliers of that type of stuff, but searching on that term produces quite a few results.

You can get HumanVerify, a free CAPTCHA system you can use on your website.
