This is probably the scariest patent I have seen in a while. Anyone with the right equipment can prevent someone else from recording them.

That includes concerts. But also police overstepping boundaries, mafiosi, riot controllers, etc...

My suggestion is to never buy a phone that has this 'feature'.

Alternatively, if you buy one, also buy a IR filter. This seems easy to defeat, as there's no way the software will require some IR signal to be present to operate.
