ASP.NET and making captcha to protect your forms: 

ASP.NET and making captcha to protect your forms Captcha is generally used to stop automatic submissions and has become almost a common sight wherever users are supposed to submit content. It is generally a test that is administered to human beings by a computer to prove that the human being is really a human being. CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". According to the free encyclopedia Wikipedia. Captcha has been applied across websites as not all submissions done on the web are useful to users. There are spammers who will try to flood websites with an intention to harm your website either for a benefit or just to have fun after seeing you in problem. A puzzle that can be decoded only by a human being is given to the user at a vantage point while submitting information. The effectiveness of your captcha depends upon the puzzle that is generated. It should be such that a machine is not able to decode it but a human being can easily decode it with a bit of common sense. ASP.NET gives you the freedom to choose captchas from texts as well as pictures. These captchas are available in the market either free or for a small cost. One of them goes by the name of BotDetect. This has fifty different captcha algorithms thus giving a wide array to be chosen by the mechanism. Apart from that it has a audio support and a built in reload captcha button. A choice between JPEG, GIF, PNG and BMP image formats.

Slide 2: 

We have the ASP captcha that has been designed to protect forms from spambots that are processed using ASP scripts. This particular method is quite beneficial as it does not require any external components. If a user has filled in a wrong captcha then generally the user is taken back to a empty form; but not while using ASP Captcha. The from is filled automatically once the user is redirected back. The best part is that you don't need any hand coding everything can be done on dreamweaver. Protecting yourself and your site and forms is your responsibility against cyber attackers take all the measures necessary for that.
