Funnily enough, my "full id" (full name, city, profession plus year) isn't unique to me unless you add a date of birth.
Maybe it's not unique with a date of birth either, but statistically it should be.
It's a regional thing, but roughly translates to "John Smith, programmer from NY, born 1995"
"Abel Davidson Carpenter of Helsinki born in the year 2020" is probably good enough an identifier.
Obviously has some issues, but it's interesting to see that this "ancient" scheme would still hold up these days.
