reCAPTCHA v3: Google today announced an update to its reCAPTCHA technology since 2007 to tackle bots on the World Wide Web.
The good news is that the new system will no longer require any user interaction. You will of course remember the first days of reCAPTCHA v1, when everyone was trying to read a distorted text or the days of v2, when we were trying to find "shop windows", "road signs" and "cars" for 1-2 minutes.
ReCAPTCHA v3 will use a new secret and proprietary technology of Google to distinguish bots from normal traffic, "observing" the behavior of users of a site.
Google says that by observing how regular users interact on a page and its sections, it will be able to detect strange behaviors, bots or unwanted actions.
New visitors will receive "risk ratings" based on their source of traffic or actions they take on a site. The scores will start from 0,1 (bad) and will reach 1 (good). According to the company, the webmasters will be able to decide how their site will react based on the above rating.
The whole system is much more complicated compared to reCAPTCHA v2, but webmasters had plenty of time to try out version 3 with a beta period starting last May.
The biggest advantage of reCAPTCHA v3 is that site owners can now control and decide how their pages will react to bots and not allow Google to make these decisions on its own, as it did with versions 1 and 2.
ReCAPTCHA v3 will be available to everyone later this week. More information at official announcement of Google.
