An anonymous reader quotes a report from Reuters: The United Nations' aviation agency is backing the creation of a single global drone registry, as part of broader efforts to come up with common rules for flying and tracking unmanned aircraft. While the International Civil Aviation Organization cannot impose regulations on countries, ICAO has proposed formation of the registry during a Montreal symposium this month to make data accessible in real time, said Stephen Creamer, director of ICAO's air navigation bureau. The single registry would eschew multiple databases in favor of a one-stop-shop that would allow law enforcement to remotely identify and track unmanned aircraft, along with their operator and owner. It's not yet clear who would operate such a database, although ICAO could possibly fill that role. The proposal, however, could face push back from users, after hobbyists successfully challenged the creation of a U.S. drone registry by the Federal Aviation Administration in court earlier this year.
