Websites could battle more bots without interrupting users thanks to reCAPTCHA v3
One of the primary concerns for webmasters is the prevalence of internet bots, automated systems that can rapidly disrupt authentic website traffic and create chaos and noise. One of the most common ways to battle bots has long been to use CAPTCHA, the “Completely Automated Public Turing test to tell Computers and Humans Apart.” You may know CAPTCHAs as the annoying prompts that ask you to type in distorted text or click pictures of trees. However, CAPTCHAs could migrate into the background completely with Google's reCAPTCHA v3, rolling out of beta this week.
According to Google, reCAPTCHA v3 “runs adaptive risk analysis in the background to alert [website owners] of suspicious traffic while letting your human users enjoy a frictionless experience on your site.” In a nutshell, reCAPTCHA v3 runs in the background of sites to which it is assigned and tries to identify patterns associated with authentic users. Each user is given a score that is then relayed to the site administrator.
Admins can set thresholds that let users pass through uninhibited or force users to under further authentication. These scores can also be used by automated systems to block unwanted traffic automatically. The whole system is designed to give admins more customization with how they use the reCAPTCHA system.
The reCAPTCHA v3 system can be deployed now by visiting Google’s developer site.
