Interesting reference. Based on the contents of this reference, you should
not use SSN for a primary key unless you work for the IRS or a
state/county/city taxing authority. The SSA is arguing that use of SSN
should be restricted to taxing authorities and banned from use by other
government authorities (such as state driver license bureaux) and commercial
organizations. I applaud the intent of the SSA, by seriously doubt that
this can be accomplished. Its use is very much embedded in US society
today.
