Your phone is watching you, here's your final discovery.

Research scientists at Northwestern University in Boston spent a year trying to determine whether smartphone applications are hiding in secret our private conversations to send personal data to advertisers.

Fortunately, researchers found no evidence to support this long theory. However, they were stumbled by another disturbing information: While your phone may not hear you, it is watching you.

Boston researchers tested 17,260 popular Android apps, many of which are owned by Facebook, and 8,000 send live information to Facebook. The study found that more than half of the surveyed applications had permission to enter the camera and microphone of users. That means they can activate these features at any time, when the app was open.

Scientists used a automated system to interact with apps, looking for any media files sent from them, especially to a third party, broadcast the ON.

When one of the phones in the study used a Gopuff food distribution app, information from the telephone interaction with the app was recorded and sent to a third-side domain connected to the Appsee.

The census sent to the company included the screen where users entered their postal code for offering food.
