This post is about a bluetooth mobile lock and unlock in ubuntu operating system in computer.using bluetooth lock for locking your computer will be much secure and safe. Your laptop locks itself down when you step a certain distance away, and opens again once you're in range. Certainly useful in coffee shop and book store situations, but not a bad idea in a house with curious little fingers around, either. This kind of measure is more utility than security device, and the instructions require serious attention (forgetting to undo one step could hose your system), but it's a nice privacy feature and seriously cool tweak at the same time and i hope ubuntu mobile bluetooth lock is useful to you.TO LEARN HOW TO INSTALL BLUETOOTH MOBILE LOCK SECURITY FOR UBUNTU FOLLOW THE LINK BELOW
