The fact that one company can hold enough information that someone else can assume your identity on paper is scary. In the U.S. we have 3 bureaus with this information. The credit bureaus, if they are going to continue to hold this information, need to be held to the highest security standards in order to protect the citizens of any nation utilizing them. The crime of allowing the data to be compromised to this extent needs to be punished and a precedent set that makes each of the bureaus question whether they should continue to exist.
Someone fraudulently uses your bankcard? You see it on your statement or the bank notices unusual activity and the bank issues you a new card/number.
Someone fraudulently uses your SSN (and you may not even know it's in use)? Unless you can prove to the U.S. government that you have been damaged in some way by the fraudulent use of your SSN, you won't be issued a new SSN.
I say sign this petition so SSN becomes a worthless commodity and they come up with a new way to ID us all that is more than a simple number:
