Research team finds disk encryption foils law enforcement efforts

(PhysOrg.com) -- A joint U.S./UK research team has found that common encryption techniques are so good that law enforcement, from local to highly resourceful federal agencies, are unable to get at data on a computer hard disk that could be used to prove the guilt of people using the computer to perpetuate crimes. In looking at the current technology, the team, as they describe in their paper published in Digital Investigation, find that if criminals use commonly available hard drive encryption software, law enforcement very often is unable find anything that can be used against them.
