WordPress Captcha Plugins for Your Website Comments, Login and Registration Forms

It is a notorious fact that people are always trying to abuse websites for both recreational and profitable purposes. Automated software or bots are often used to engage in the attack. The issue escalated to the point where. As the abuse became profitable, the scale of abuse grew using automated software (sometimes referred to as bots). To prevent bots from overrunning sites with spam, fraudulent registrations, fake sweepstakes entries, and other nefarious things, publishers responded by testing users to see if they were human or not. This test is known as a Captcha. CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”.

Even though this measure was implemented to enforce security, there were ways in which they could be bypassed. This means even though a captcha should differentiate between human and machine, techniques were use to go around that system. One such procedure was Optical Character Recognition (OCR). OCR is the process by which computers convert human readable text into digital. These values can then be understood by computers. This means a bot could fool a website into thinking it was a human being. Since bots have improved in terms of bypassing CAPTCHA through OCR, most providers have responded by making their puzzles harder to read. You may find the squiggly, chicken scratch captchas annoying and hard to understand but it is for your own protection. Other types of captchas include simple mathematical calculations, choosing an image from a set of images to match a specific word.
