Autonomous drones: opportunity or threat to privacy and security?

I built a small quadcopter myself: I assembled the motors, the Pixhawk flight controller, and a GPS module, then added a Raspberry Pi for image processing. At first, the drone flew freely in my garden, but soon I noticed neighbors complaining about the buzzing noise and the drone flying over their windows. So I implemented a software geofence in the firmware: whenever the drone approaches a delimited area (defined by GPS coordinates I got from Google Maps), it triggers an automatic "return-to-home." This solution worked, but it also showed its limits: if the GPS is jammed or the signal is lost, the drone can cross the virtual barrier without detecting it. This experience convinced me that the simple rule "mandatory geofence" is not enough if it remains a software function that can be disabled or bypassed. We need to combine the software constraint with a hardware lock—for example, a security module that refuses any flight outside the perimeter even if the firmware is reflashed—and require it to be certified by an independent body. At the same time, current legislation (which is mainly based on weight and flight distance) does not adequately address full autonomy scenarios. Encryption standards for command links, requirements for owner identification, and radio spectrum access control would be necessary additions to ensure drones remain useful (mapping, rescue, etc.) without becoming tools for surveillance or attack.
