An anonymous reader writes "In a breakthrough that could aid spies, keepers of medical records, and parents who want to prevent their kids from 'sexting,' a team of Virginia Tech researchers has created software to remotely put smart phones under lockdown. The phones are given permission to access sensitive data while in a particular room, but when the devices leave the room, the data is completely wiped. A general, for example, could access secret intelligence while visiting a secure government facility without fear that his or her smart phone or tablet computer might later be lost or stolen, the team's lead researcher said. 'This system provides something that has never been available before. It puts physical boundaries around information in cyberspace.'" Unless the phone or other device can also take screenshots, or doesn't have that software installed.
