Apparently this is in the works: http://www.dailydot.com/technology/lightcense-drone-identification-system/ http://www.dailydot.com/technology/lightcense-drone-identifi... Instead of the standard alphanumerical plates that are affixed to cars, drones would be equipped with a set of bright, multicolored LED lights. The lights would flash in a unique sequence that would correlate to the owner. A smartphone app would identify the pattern and search the database for the operator the vehicle is registered to. pretty ingenious if you ask me.
