Apple has won a patent for technology that can stop people from using their iPhones to film live events. The company finally won approval for a patent it first submitted in 2009 involving technology that can turn off an iPhones’s photograph and recording functions. An “emitter can generate infrared signals with encoded data that includes commands to disable the recording functions of devices,” the filing reads. “An electronic device can then receive the infrared signals, decode the data and temporarily disable the device’s recording function based on the command.” The technology could protect copyright holders from having their content uploaded to YouTube, but others warn the technology could be used to impinge free speech and expression. There’s no word yet on how or when Apple plans to implement the technology.
