Another thing that interests me to solve this is via hardware. There are devices like Tile, Trackr available in the market but they are easily recognizable and thieves will detach them. Alternatives to that could be: - A paper thin version of above mentioned devices that can be pasted on laptop OR - Replacing a keyboard key with any of the above devices The hardware will do two things: 1) It will tell the location of the device and 2) It will 'factory reset' the device so that the data doesn't fall into wrong hands. What do you think?
