NOTE: The following article has nothing to do with genealogy. However, it concerns me and I think everyone should be aware of these invasions of privacy.
You probably have a tracking device in your pocket. You are helping government spies, hackers, burglars, and cell phone companies track your every move. Every time you place your cell phone in your pocket or purse, you are on the radar and your movements, position, orientation, and conversations are all open to someone. In fact, that happens whether you place a call or not.
The “smart phones,” such as an Android or Apple phone, provide the most information about your movements and activities, but even the so-called dumb phones are almost as bad. All cell phones track your location. The “smart phones” simply provide additional accuracy as to your location. Instead of tracking you plus or minus a mile or so, a smart phone or even a dumb phone that has a built-in GPS will identify your location within a very few feet at all times.
Want proof? Look above and to the right to see a map available on Google that tracks my recent travels with an Android phone in my pocket. Click on the map to view a larger version. You can see where I traveled in considerable detail.
