What's the big deal?

UIDAI has taken up the herculean task of assigning every single one of India’s 1.2 billion citizens a Unique Identity (UID) number.

If you’re beginning to wonder what the big deal really is, consider this: By 2014, the government wants half of India’s population to be allotted UID numbers. To do that, the Authority will photograph a staggering 600 million Indians, scan 1.2 billion irises, collect six billion fingerprints and record 600 million addresses.

Let’s put this simply. No system in the world has handled anything on this scale. Period.

Think about it.

When the 600 millionth person is assigned a unique 12-digit UID, the system that generates it will have to compare it against 599,999,999 photographs, 1,199,999,998 irises and 12,999,999,990 fingerprints to ensure the number is indeed unique.

By the time the system reaches out to cover every Indian resident, the complexity, well, doubles. When in full flow, the system will be adding a million names to its database every single day until the task is complete.
