Comment Id numbers shouldn't be required to be secret (Score 1) 57
The idenfitifaction numbers shouldn't be required to be secret. They should be used for just one purpose - to identify a person in a database, to act as a foreign key so the government databases can join together all data they have on you using it as a key. Or some private company as well.
It shouldn't be ever used to authenticate people, but that's how the SSN is used in the US and what's causing all these problems. It should be required that you show a valid identification document with your picture on it, that also includes your ID number.
If I know someone's ID number here in Estonia, then all I can do is guess their age and sex from it. That's it, when you apply for a credit card you have to show some kind of document, so this fuss about ID numbers being secret is just insane and inconveivable for anyone outside the US.
Here (in Estonia), if we need to identifi and authenticate ourselves to the government or some private company (banks to do online banking, telecoms to check the phone balance or whatever, change the cable tv package) we can use our ID card which has a private key on the chip and requires the knowledge of a PIN code for authentication, another PIN for giving digital signatures.
The Japanese are doing it a bit wrong, they should put their "my number" of id documents like passport or drivers license. Roll it out when peoples documents expire and they have to get new ones.
