As more people begin to use drones there is a very definite threat to the privacy of people. It is possible for a drone to record activities of a full neighborhood without the residents being any the wiser. This can be potentially dangerous specially if used with the wrong intention.

Cyber security researchers at Ben-Gurion University of the Negev (BGU) and Weizmann Institute of Science have some ideas that can help. They have come up with a simple method that allows a person with a laptop and a flickering object to check if a drone is recording a specific target.

The Israeli researchers have come up with a couple of ways to check if your privacy has been invaded. The best part of the science project is that it can be done by anyone. It does not require any sophisticated hacking or cryptographic breaking skills. It uses smart film and a software along with something called an FVP channel.

They have done a couple of successful demos wherein the cyber security researchers were able to positively identify that a neighboring drone was indeed recording the house. This could go a long way in military use as well as for civilians who will now be able to prove that their neighbors violated their privacy.
