We all have had a laugh while ticking off the ‘I am not a robot,’ check box. What is the point of it anyway? Well, Google is taking away your joke with the newly announced reCAPTCHA service. The service can tell the humans apart from bots without requiring any additional input from the user.
Unlike the CAPTCHAs and reCAPTCHAs available previously, the new one uses machine learning and enhanced risk analysis engine that analyzes web browsing behavior. Now you won’t have to stare at a twisted or blur image to solve a CAPTCHA unless your browsing patterns are suspicious.
CAPTCHAs do have a point; they prevent malicious bots from attacking websites which otherwise can be spammed or subjected to some kind of exploitation. So yes, the web developers need to make sure if the user entering their site is a human or a bot.
All the CAPTCHAs that you have solved to this day have helped strengthen Google’s machine learning algorithm by enriching the database for digitizing and transcribing images to text. Google even uses this information in transcribing books and improving maps.
