Doesn't surprise me at all and seems like a good solution to the problem of human verification. It won't take long for AI to catch up to that, but this captcha method might hold for a couple of months.

Not sure what problem everybody here is having with this. The alternative would be device certificate stuff (ala did Apple sign for this being a proper Apple device?). Having to shake your hand sounds a lot more privacy friendly. Are you guys seriously worried that Google is gonna steal your secret handshakes?

I saw a post on the GrapheneOS forum of someone who was accosted by Google with this requirement, so they are certainly using it.

It's interesting the parallels of Google's recaptcha and Cloudflare turnstile.

Cloudflare is free, no image selector, allows VPNs and Tor for the most part, just 0 click with a good ip reputation and 1 click with a bad one.

Recaptcha is paid, trains waymos, sucks millions of hours of human time, asks for camera access, asks for a phone attestation, blocks VPNs/Tor.

Thank god less sites are using ReCAPTCHA.

Looking forward to some other solutions gaining prominence eventually as well.

Like that Anime girl one.

What if you don't have a cam or a hand?

Imagine getting your hand wrongly blacklisted as a fake, and then someday down the road you make a wrong gesture during an online interview and now your real-name is also on the suspicion list.

I could see this being privacy friendly if the user could see exactly what Google was using.

For instance, terminalcam, gives just enough data to reveal liveness without necessarily giving enough information about identity.

can a unique fingerprint (no pun intended) be extracted from hand geometry

My openclaw agent gonna find some way around it.

The non-mandatory internet that requires any captcha at all is becoming non-existent to me.

things are getting out of hand :D
