However the methods right now are not 100% effective as concertgoers are still taking photos and videos even when told not to, but it seems that Apple has come up with an idea that could stop them in their tracks. This is according to a recently discovered patent which outlines an idea Apple has to prevent users from taking photos or videos in concerts.
How does this work? Basically the concert organizer will have a device that emits infrared signals. Whenever a phone is pointed at the stage, it will receive that infrared signal which would then have the ability to disable the phone’s camera/recording function, thus rendering the user’s phone useless as a camera for the time being.
Alternatively to prevent bootlegging, the infrared signal could also deliver a watermark to the photos or videos so that whoever is recording it can’t claim that it is their property. That being said, the patent was filed back in 2011 and given that we’re in 2016, it’s safe to say that if Apple was planning on implementing such a feature, they would have done it by now.
