CAPTCHA Security and Why It's Important


It’s easier to put in those wiggly words and numbers than to reclaim your identity. Those wiggly words and numbers are more than just nuisances (and, hey, even we can admit that they’re a little annoying sometimes). CAPTCHA is a program that protects websites against bots by generating and grading tests that humans can pass but current computer programs cannot. It’s an efficient security measure that is protecting websites from harmful viruses and anything that may jeopardize their site and information.

The way it works is relatively simple; humans can read distorted text while computer programs cannot. By filling out the CAPTCHA the website deems your log-in safe and genuine.

CAPTCHAs play an important role in keeping the internet spam-free and making everyone’s experience a little bit better. reCAPTCHA also makes positive use of the human effort spent in solving CAPTCHAs by using the solutions to digitize text, annotate images, and build machine learning datasets. This in turn helps preserve books, improve maps, and solve hard AI problems. says Google.

The Geek Daily has highlighted a few key ways that CAPTCHA’s are helping websites; CAPTCHA prevents the website or blogs from comment spam as well as dictionary attacks. Dictionary attacks are the type of attacks under which an automatically generated script or computer program tries random passwords on login forms in case of unsuccessful login.
