I suppose it was inevitable that the DRM wars would come to the world of drones. Reporting for the Wall Street Journal today, Jack Nicas notes that:
In response to the drone crash at the White House this week, the Chinese maker of the device that crashed said it is updating its drones to disable them from flying over much of Washington, D.C.SZ DJI Technology Co. of Shenzhen, China, plans to send a firmware update in the next week that, if downloaded, would prevent DJI drones from taking off within the restricted flight zone that covers much of the U.S. capital, company spokesman Michael Perry said.
Washington Post reporter Brian Fung explains what this means technologically:
The [DJI firmware] update will add a list of GPS coordinates to the drone’s computer telling it where it can and can’t go. Here’s how that system works generally: When a drone comes within five miles of an airport, Perry explained, an altitude restriction gets applied to the drone so that it doesn’t interfere with manned aircraft. Within 1.5 miles, the drone will be automatically grounded and won’t be able to fly at all, requiring the user to either pull away from the no-fly zone or personally retrieve the device from where it landed. The concept of triggering certain actions when reaching a specific geographic area is called “geofencing,” and it’s a common technology in smartphones. Since 2011, iPhone owners have been able to create reminders that alert them when they arrive at specific locations, such as the office.
This is complete overkill and it almost certainly will not work in practice. First, this is just DRM for drones, and just as DRM has failed in most other cases, it will fail here as well. If you sell somebody a drone that doesn’t work within a 15-mile radius of a major metropolitan area, they’ll be online minutes later looking for a hack to get it working properly. And you better believe they will find one. Continue reading →
