HTMLCaptcha
is an assembly that allows ASP.NET developers to verify the humanity of the users of their site, using a simple (and effective) method known as CAPTCHA.
It works like this:
HTMLCaptcha randomly outputs a small icon-sized HEC image -- a real picture, not skewed text --
created entirely in HTML/CSS, and then offers a random selection of descriptions. The user must select the correct descriptor in order to validate.

Features & benefits
- Eliminate bot registration and posting
- Add effective human validation to your site and apps. Kill auto-registration and spamming.
- Make it easy on your users
- Eliminate registration altogether (in some cases). Save users from registration burnout.
- No image file generation
- No files to create and save. Image data is encoded entirely in HTML and embedded in the web page. Convenient and fast.
- Image-based CAPTCHA
- Instead of hard to read, skewed text, simple, user selected images are output. Easy for humans, hard for computers.
- Create your own CAPTCHA images
- You can create your own custom CAPTCHA images, making the A.I. problem even harder. Create and use any number of image sets.
- ASP.NET ready
- Simply add a reference to your ASP.NET project and integrate HTMLCaptcha into your web page. Binds easily to ASP.NET controls.
- Integrate seamlessly
- Becomes just another form element in your page. As seamless as adding a form control or outputting some dynamically generated HTML. Becomes more difficult for software
to extract the image from the page contents.
- Hard A.I. validation
- CAPTCHA is a proven technique for minimizing the effectiveness of spam bots and auto-registration. HTMLCaptcha takes this powerful method to the next level in convenience, usability, and security.
