Picture CAPTCHA for ASP.NET

Picture CAPTCHA for ASP.NET is created as a special and image-based CAPTCHA which prevents spam and bots in a simple and intuitive way for your Web site visitors. Rather than forcing people to decipher warped and distorted characters or words, Confident CAPTCHA presents a grid of randomly-generated pictures and simply asks the user to click on specific pictures to verify that they are human and not a bot. Text-based CAPTCHAs have become so difficult to read that visitors become frustrated and abandon the action or the Web site completely.

Confident CAPTCHA is easy on people while being tough on bots. It improves the user experience, helping increase conversion rates and user interactions on your website. Use Confident CAPTCHA to stop spam and bots on Web forms, comment posts, new account registrations, polls and surveys, and many other areas of your Web site. Confident CAPTCHA is very configurable. The Web site owner can choose: the number of images to display; the number of images that the visitor must click; order of category selection; background color; optional audio verification for the visually impaired.
