Re: Voice ID, over the phone, for financial security?
"Given how alike family members can sound and given the quality of the average phone line"
I've recently had a few phone conversations with a cousin for the first time in years and it's amazing how like her mother she sounds. I'd be surprised if the system could tell them apart.
In passing I discovered that mailname@hotmail.com doesn't go to the same mailbox as mailname@hotmail.co.uk. I'd assumed they would and the fact that it isn't seems to open the door to impersonation without faffing with UTF look-alike characters.
