Facebook wants to activate the microphone of your mobile phone with the help of commercials on the TV and get even more data

It seems that the fear of invading Facebook's privacy by its users is far from over. This is because the company has just registered a patent which, if used, can secretly activate the microphones of your smartphone when performing commercials.

The patent is described as a signal can instruct the smartphone to record "surround sound" surrounding the device, identify the owner information of the smartphone user then send a sample of the audio to Facebook for badysis.

"The online system, based on and identifies the individual and the corresponding content element and records an impression on the content element after the determination that there was a print of the certified content element identified, "reveals the patent.

A non-audible sound signal for human ears is issued during an advertisement so that the smartphones of its users can understand the signal and start recording.

The call would be extremely useful for recording the reaction of viewers during advertising but obviously that recording their audio secretly and without permission from the user is something that we all very much afraid, especially after the great controversies

The smartphone interprets the high-pitched signal in advertising or other content.

An "ambient audio print" is then generated which is stored in an "online system" which also identifies information about the person to whom the smartphone belongs .

The data is sent to Facebook, which discovers if the person looked at the ad and if there was a commitment.

This information would be used by Facebook to allow the social network to indicate more relevant ads to users. ] In the picture above, Zuckerberg appears next to his laptop which has a camera and microphone covered with tape. Is this the best way not to become so exposed to Zuckerberg's own social networking tools?

Despite registering the patent, Facebook states that it has no intention of implementing technology . In a statement, Facebook vice president Allen Lo said the patent had been registered "to prevent aggression from other companies," noting that "patents tend to favor technology-oriented to the future and may be marketed by other companies.
