Security:

UUID - universal unique identifiers

“…After generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%.

The probability of one duplicate would be about 50% if every person on earth owns 600 million UUIDs…”

fig.9LINUX blog (2007)

UUIDs are generated as needed..there is no registry
