TALLAHASSEE, Fla. (AP) - The University of Florida has notified 239 former students that a computer security breach has compromised their Social Security numbers and other personal data.

School officials said they mailed letters to the former students Wednesday. They could not find contact information for another 54 students.

The information was part of a web-accessible archive of computer science class information created by a faculty member in 2003.

The website was removed from a server immediately after it was discovered last month.

The university had used Social Security numbers to double as student identification numbers until 2003 when the practice was stopped.

Officials said they were unsure whether the information was accessed or used.
