Patent 9651944 was granted and assigned to Microsoft on May, 2017 by the United States Patent and Trademark Office.
Unmanned aerial vehicle (UAV) piloting authorization implementations are presented that authorize a pilot to operate a UAV in regulated airspace. In general, a UAV authorization system is employed which incorporates a control authorization unit into a UAV controller device and a control instruction authentication unit into a UAV. The control authorization unit obtains a signed digital certificate associated with a UAV pilot, checks that it is signed by a trusted signatory, and then determines that it is currently valid using cloud or server based validation service. If the digital certificate is currently valid, the pilot is allowed to initiate control instructions via the UAV controller device. The signed digital certificate is attached to any control instructions initiated by the pilot before transmission to the UAV. The control instruction authentication unit goes through a similar procedure to authenticate any received control instruction before allowing the UAV to execute the instruction.
