Those "Grandma send money to your grandson to bail him out" scams are about to get a lot more interesting. It's one thing to convince your grandparents never to send money to random people calling on your behalf, but if the conversation happens in your voice? How do harden against such an attack when dealing with people who are technologically illiterate?

Perhaps this opens up a market for secure identity verification that is accessable to the layman...

To be fair, these scammers already claim to be the grandson. My grandma got a call from me, from jail, in Mexico. I guess I had a little too much to drink at a wedding, and I had a cold, so my voice was a little off. And I desperately needed to post bail in a foreign country.

It wasn't the voice that tipped my grandma off. Just that I do not drink. So that was close.

This isn't really that hard to fix, and it's basically horse-battery-staple a la Hogwarts dorms. Families need to establish a verification phrase or word and ask "what's the password?" if there is any doubt about identity. Given deepfakery of images, even a video call won't be safe in the future and personal info about people can be datamined, so the "3 security questions" approach is also already useless.
