Facebook patents system that can use your phone's mic to monitor TV habits

The Guardian -------- Facebook has patented a system that can remotely activate the microphone on someone’s phone using inaudible signals broadcast via a television. The patent application describes a system where an audio fingerprint embedded in TV shows or ads, inaudible to human ears, would trigger the phone, tablet or long-rumoured smart speaker to turn on the microphone and start recording “ambient audio of the content item”. The recording could then be matched to a database of content to allow Facebook to identify what the individual was watching – like Shazam for TV, but without the individual choosing to activate the system.
