Amazon gets US patent for ‘countermeasures’ to protect drone delivery – CNBC

Amazon received a patent that covers technology to give it extra anti-hacking protections when drones are out are doing deliveries, according to the U.S. Patent and Trademark Office.

Amazon, which has dubbed its drone-based delivery service Prime Air, recently had its first actual drone delivery using the technology.

The e-commerce giant initially filed in 2014 for the patented technology covering “countermeasures of threats to an uncrewed autonomous vehicle.”

Amazon said in the filing the UAVs, or drones, can be targets of a “malicious person” using a wireless signal jammer and it indicates there could be “a variety of adverse effects including the UAV crashing.”

The technology patent is based on both a so-called mesh network and the process of several drones communicating with one another through the sharing of data “to confirm or cross-check data such as location, heading, altitude, and so forth” — all designed to detect data differences and possible signs of a drone being compromised.

“Disagreement between data generated by the first UAV with external data from the second UAV may result in the determination that the first UAV is compromised,” the filing explains.

Moreover, the filing reveals that communications links on the mesh network can be encrypted and use other techniques such as “frequency hopping, spread-spectrum, and so forth, to maintain security, reduce interference.”
