reCAPTCHA v3: Google today announced an update to reCAPTCHA technology available from 2007 to tackle bots on the web.
reCAPTCHA v3, therefore, is the new edition and this is a complete update of it technology reCAPTCHA that we knew until today.
The good news is that the new system will no longer require any user interaction. Of course you will remember the first days of reCAPTCHA v1, when everyone was trying to read a corrupted 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 uses a new secret and proprietary Google technology to distinguish bots from normal traffic by “observing” the behavior of a website's users.
Google says that by observing how normal users interact in a σελίδα and its parts, will be able to detect strange behavior, 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 than reCAPTCHA v2, but webmasters have had plenty of time to test the 3 version with a beta session that started 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 will not allow Google to make these decisions on its own, as was the case for 1 and 2.
ReCAPTCHA v3 will be available to everyone later this week. More info at official announcement of Google.
