Renonymization: An example
An article in Wired, titled Social Security Numbers Deduced From Public Data, says,
By analyzing a public data set called the “Death Master File,” which contains SSNs and birth information for people who have died, computer scientists from Carnegie Mellon University discovered distinct patterns in how the numbers are assigned. In many cases, knowing the date and state of an individual’s birth was enough to predict a person’s SSN.This is a great example of renonymization, or, as one commentator suggested, renomynization.
