Scientists in Finland have developed a new way to protect mobile phone’s owner from theft or unauthorized use. With the motion sensors technology, the phone will be able to record its owner movement and walking habit. It will periodically check to see that it is still in the possession of its legitimate owner by measuring the current stride and comparing it against that stored in its memory. If it fail to identify the current owner, in other words, the phone has possibly fall into a wrong hand, when the user try to make a call or access its memory, the phone will automatically prompt for a password.

The current prototype phone has 96% of the time correctly identified when someone other than its owner was carrying it. But according to Heikki Ailisto, one of the scientist at VTT Technical Research Centre of Finland who develop this technology, the system will only work best when it was attached to a user’s belt and proved much less reliable when carried in a bag or purse.
