Well, statistically speaking fingerprints are unique enough for a small country. In a big country, things will be different.
One in one hundred million people have identical fingerprints. Identical in the sense that differences are small enough to not be recognizable with
current methods of taking those prints into some database. In courts, identical fingerprint it all it takes.
So, in USA with 300 million people.. If every one of them gives fingerprints into a database, you usually encounter three people that evidently
committed some crime, and it stands in court. This is not a problem because authorities propably don't have a hundred million fingerprints in their
Whenever we get a global database with 7 billion fingerprints, we will get about 70 matches for each crime where fingerprints are used as evidence.
Then, in today's global world, there will be problems and fingerprints will no longer be accepted as solid evidence.
However, when you combine travel data, working times and several other things, you can rule out 69 of those 70 with identical fingerprints and have
your committer of crime convicted.
