X, sometimes referred to as Mr. X, is a fictional character on the American science fiction television series The X-Files. He serves as an informant, leaking information to FBI Special Agents Fox Mulder and Dana Scully to aid their investigation of paranormal cases, dubbed X-Files. The character serves as a replacement for Deep Throat, who had been killed off in the first season finale, The Erlenmeyer Flask.
What Information is Personally Identifiable? Mr. X lives in ZIP code 02138 and was born July 31, 1945. These facts about him were included in an anonymized medical record released to the public. Sounds like Mr. X is pretty anonymous, right? Not if you're Latanya Sweeney, a Carnegie Mellon University computer science professor who showed in 1997 that this information was enough to pin down Mr. X's more familiar identity -- William Weld, the governor of Massachusetts throughout the 1990s.
