An Authentication/Biometric Control/Component by Arbinger Systems

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 by randomly outputting a small icon-sized image -- a real picture, not skewed text -- created entirely in HTML/CSS, and offering a random selection of descriptions. The user must select the correct descriptor in order to validate. This is a highly flexible component that may be used in many ways.

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 HTML 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.
