Let’s be honest, ticking the correct checkboxes in Google CAPTCHA is difficult for human beings. Maybe, Google has taken a cue and has ended the CAPTCHA check box mechanism. The puzzle boxes have been replaced with a behavioral analysis mechanism to ease the captcha related issues faced by the users.
CAPTCHA or “Completely Automated Public Turing Test to tell Computers and Humans Apart” is deployed by Google on websites to make sure that human beings and not robots access the websites.
Google has improved the CAPTCHA mechanism over the years. Earlier, users had to enter some distorted numbers and alphabets that appeared. Then came the mechanism which included picture matching puzzles.
Ticking CAPTCHA boxes was a challenge for those suffering from vision-related syndromes. Therefore, Google has introduced reCAPTCHA v3, which returns a score on the basis of a user’s behavioral analysis. Using this score, the company can determine the authenticity of the connection. Websites can allow or disallow users on this basis of this score.
Websites can also customize this score by making a filter that analyzes the connection from CAPTCHA score and any previous information of the user stored by the website. The score can also be used as a signal to train a machine learning model by websites.
A new feature named ‘Action’ has also been introduced in reCAPTCH v3 that is aimed to curb cyber attacks. CAPTCHA scores from different websites can be studied to decipher a pattern used by the attackers.
Wei Liu, Google Product Manager of reCAPTCHA said in an official blog post, “We are fundamentally changing how sites can test for human vs. bot activities, by returning a score…and eliminating the need to interrupt users with challenges at all,”
