Google has introduced reCAPTCHA to fight spam and abuses by robotic software. For years, Google has been using captcha as an essential way to ascertain user is not a robot. It asks users to read distorted text and ask to type in the box before proceeding in the website. It was helpful in preventing spam on the internet.
Google has used captcha for long assuming that robot can’t read or solved distorted texts. But recent report of Google research has shown that even distorted texts can be easily read by robots using artificial intelligence technology with 99.8% accuracy. Hence, it was no longer useful in preventing spam.
To counter this problem, Google developed an Advanced Risk Analysis backend for reCAPTCHA which involves entire user engagement with captcha before, during, and after – helping to determines a user is a human or robot.
Users face lots of problems in reading and solving text in the captcha. Keeping this problem in mind, Google has introduced this re-captcha. It directly asks a user whether they are robot or human. It helps the users to securely verify that they are human by clicking in “I’m not a robot”. Using this new API user no longer needs to see what is there in the box.
However, if the risk analysis engine can’t predict confidently that it is a human or abusive agent, it will quickly show captcha to enter and gather more clues. In this way, it increases security checkpoint for robot preventing spam.
reCAPTCHA is also mobile friendly as it is easy for users to clicking on pictures than typing distorted texts in small devices. Earlier, it was observed that a significant percentage of traffic was lost due to captcha. Platforms like WordPress, Snapchat, Humble Bundle, etc have adopted this and getting higher traffic than ever with faster sites. So, it is high time for you to adopt reCAPTCHA on your website to achieve more conversion and faster site.
