That train has already left the station. E.g. If you renew Driving License in most large cities RTO stores digital fingerprints+ photograph. If you register any property transaction in Mumbai, you have to supply digital fingerprints.
Do they simply store prints or do they have software and a process that identifies difference in prints against the same name as well as similarity of prints against different names? Everytime a new entry is made, it has to be checked with all existing records.
That is known as deduplication. It has never ever been tested on more than a few million and has error rates in excess of .025% in laboratory conditions. Work out the maths.
All this system does is, it centralizes this storage and reduces cost since each govt agency does not have to roll its own solution.
I agree. Centralisation makes compilation of inputs and analysis of data easier.
And introduces vulnerabilities and exploits, both technical and political. UK scrapped such a system because of the above and becuse the risks far outweighed the benefits.
