Well, you have to provide the full name. Bummer :D

I assume the news would also be much shorter but slighly more confusing if we just called all "Joe"s "Joe" ?

Whereas they would be much less ambiguous but slighly harder if we all had a uuid assigned at birth. (Or maybe a checksum of our DNA ?)

Checksum wouldn't work for identical twins

Would work for many using whole genomes. CpG methylation patterns could also work.

"Despite the important role that monozygotic twins have played in genetics research, little is known about their genomic differences. Here we show that monozygotic twins differ on average by 5.2 early developmental mutations and that approximately 15% of monozygotic twins have a substantial number of these early developmental mutations specific to one of them."

USCIS stores a hash of your face when you enter and exit the United States. It's why they make you look at the camera.

A hash like a trapdoor, impossible to get properties of the face back? Or a hash in the sense of not a picture but just some important parameters, but still reproducible?
