Social Security Numbers don’t have to be predicted – they are known

A few researchers have done some work in predicting Social Security Numbers. I haven't read the report yet, but am not sure how significant this news is. I think it is fairly common knowledge that there are geographic and time elements to social security numbers.

More importantly, we don't really have to predict SSNs, because they aren't secret. In a typical lifetime, over 150,000 people will have legitimate access to your SSN (my estimate). No need for predictions, it is just available information.

Treating SSNs as secrets is part of our ongoing identity crisis.
