ATHENS, Ohio -- Two Ohio University graduates whose Social Security numbers were among 173,000 possibly stolen from school computers have filed a lawsuit, alleging their right to privacy has been violated.

Donald Jay Kulpa, 31, of Cincinnati, and Kenneth Neben, 34, a former Columbus resident now living in North Bergen, N.J., filed the lawsuit in Columbus on Friday. On the same day, the university's board of trustees agreed to spend up to $4 million to bolster computer security.

The lawsuit, which seeks class-action status, asks a judge to order the school to pay for credit monitoring services for those affected. It also requests compensation for anyone who suffers financial losses from the breaches.
