ASP.NET captcha

Overview

CAPTCHA is the acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart,” and is the most popular technique used to prevent computer programs from sending automated requests to web servers. These can be used for meta-searching search engines, performing dictionary attacks in login pages, or sending spam using mail servers.
