The Rising Threat from Bad Data: "Steven Calderon had a clean record, a clean conscience and no reason to think that his new employer's routine background check would cause any problem at all. Then the sheriff showed up at the office and took him to jail on warrants for child molestation and rape.
A nightmare? Sure, but Calderon figured it was a mistake that could be cleared up pretty quickly. He'd reported the theft of his Social Security number and birth certificate in 1993, so it was obvious that the bad guy was whoever had stolen Calderon's identity."
