What Captcha does? How does it work? Basically this tool requires the typing of the letters from a distorted image into a letterbox to determine whether the user is a machine or a human. It was originally designed to prevent scripts and robots (or “bots”) from spamming or pulling content from websites. While this tool is appreciated by website owners and hosts, it was found to be very irritating for users and website visitors because they feel forced to prove they are not robots. Some find this tool to be completely useless since it sometimes fails to recognize if the letters are correct even if they are, or let you in even though the words are totally different.
The main reason Captcha was not approved by everyone is mainly because it presents serious problems for users with hearing or visual impairments, also users complain that their everyday work activity is slowed by words illegible for people without any disabilities at all. Even though the tool provides an audio CAPTCHA that can be downloaded as a file, designed to help people with visual impairments to read the file, it sometimes contains background noises that can be obstructive. The Australian Communications Consumer Action Network’s CEO Teresa Corbin has stated “CAPTCHAs fundamentally fail to properly recognize people with disabilities as humans.”
No Captcha reCaptcha is Google’s new idea. This tool is considered to be less annoying for users and website visitors because it doesn`t ask you to type the letters from a image just to prove you are human. Instead it requires the user to type in his or her name, e-mail address and favorite color, then he or her will have to check the box that says “I`m not a robot”.
This new API can already be found across the web and according to Vinay Shet, Product Manager, websites that adopted this tool like Snapchat, WordPress and Humble Bundle are already reporting great feedback for this new tool. Even though many websites use the new API, Google does say that this is not the end of CAPTCHAs, as users will still encounter them while surfing the web.
