You can't beat fraud by removing privacy, because the mere fact that a 
person can retain their privacy and oppose another using their identity 
fraudulently proves the fraud.

Giving our private information increases the chance of fraud multiple.  I 
know, I have a father who uses my name, date of birth and address as a 
means of identifying himself as me.

It's hard to prove I'm me, when he knows my details and identifies himself 
as me first.  Who am I?  According to some, I'm not who I claim to be.
