A federal district judge dismissed much of a class-action lawsuit filed against the Department of Defense, its TRICARE insurance program and Science Applications International Corp. over a massive data breach. In September 2011, a thief broke into a SAIC employee's car, taking a GPS system and backup tapes that contained protected health information--names, addresses and lab tests. The data breach affected 4.7 million people, including military members and their families. In the May 9 ruling, the judge said that 22 of the 33 plaintiffs selected to participate in the suit on behalf of the entire class cannot demonstrate harm. Article
