Captcha stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”. A captcha is a type of challange response system programme to stop spamming. It is work as security checks to prevent hacking of a web form.
What is use of CAPTCHA
Captcha ask a user to perform a type of task that a bot can’t do. These tasks involve JPEG Or GIFs Images because while bots can identify the existence of an image by reading source code, they cannot tell what the image depicts. Sometime CAPTCHAs are so difficult that human also haven’t understand. So there is always an option for requesting a new Captcha.
Bypassing CAPTCHA
If you are the one like me who don’t want to waste time in solving Captcha then there are many browser addon like Rumola, Captcha Be Gone, AntiCaptcha etc. which might helps you to bypass the Captcha. These Browsing Add-on are created by third parties so users should be aware that the browser extension could expose their browsing activity to untrusted sources. As CAPTCHAs are also evolving new security and it can be difficult for the add-on programs to keep bypassing it up and another reason not to use CAPTCHA bypasses is that the performance of the extensions are inconsistent means sometimes they work, sometimes not !. You can try your luck!
