Q: What is so special about Game of Drones methods compared to other methods?
A: Other methods can detect a nearby drone. But, they all fail to detect whether a specific POI is being streamed by a drone or not, a distinction that depends on the camera angle instead of the drone's location.

Q: Can I apply Game of Drones methods?
A: Yes you can. All you need is a laptop (with Linux OS) and a controlled flickering LED strip.

Q: How is the streamed POI revealed?
A: Modern video encoders use compression (delta framing) algorithms in order to provide high quality streams. There is a strong connection between the percentage of changing pixels in a frame and the bitrate that is required to encode the stream. Forcing a change to the pixels in a streamed video requires a higher bitrate to encode stream.

Q: Does detecting a streamed POI from an encrypted FPV channel require crypto-analysis/hacking skills?
A: No. Anyone with a limited set of computer skills can detect what is being streamed from an encrypted FPV channel by applying our methods.

Q: Can these methods be applied to other FPV channels besides Wi-Fi FPV?
A: Yes. We demonstrated our methods on Wi-Fi FPV, because it is so popular. You can detect a streamed POI from an encrypted FPV channel of any drone that uses delta framing algorithms for video encoding. However, you need to find the demodulation protocol (from layer 1 to layer 2) that converts the intercepted radio signals to binary.

Q: What is the impact of this research?
A: This is a game changer in the battle on privacy. It empowers the victim.

Q: What areas will be influenced by this research?
A: Some armies use drones for their daily tasks. For example, one of the units of the Israel Defense Forces uses the DJI Mavic. In addition, supplying a watermarked radio signal that was intercepted from a drone might even be considered as a proof in a court of law that a drone was used for spying on a specific target.
