I guess there is no need to explain what is captcha and how it functions. I bet all of you came across it many times while registering a new account, filling out some online forms or downloading something.

Obviously, the main goal and purpose of captcha at any website is to prevent spam. One of the most popular types of it is a text based captcha: usually it’s a combination of random distorted alphanumeric characters, which cannot be comprehended by robots and machines. Sure, humans can recognize the symbols, as we are able to perceive patterns visually.

But does captcha really control spam? Basically, spam is human- or machine-generated bulk messages, distributed online. That’s no news that spam can be used to manipulate online content, post unethical links on sites, access confidential information or spread malicious code.

First of all, captcha helps to distinguish between a human and machine, because more often spam is generated automatically by machine bots.

There are different types of captcha, which help to prevent your website from spam attacks: text or image recognition, logic questions, friend recognition and user interaction. Each type has its own set of advantages and limitations, but more or less can help you to protect your website data and your visitors. Captcha is one of the essential tools for web security, don’t underestimate it.
