This whole discussion starts with what the population knows: Google (and many related databases of information) are not only distributing information, they are collecting information. Of course then they can distribute their collected information of our inputs to others. In my opinion, the problem lies in the availability of this knowledge. Presumably, 9 out of 10 citizens do not know that what they like on Facebook or what they search for through Google is recorded and stored in the company's databases. A couple of Austrian lawyers published an article in the International Review of Law, Computers and Technology and made note to mention that, "individual service providers collect more and more information on individual users, which generates privacy problems" (Schweighofer, 2013). The collection of items and inputs happens constantly, yet people do not understand what is happening. Social acceptance of accepting terms of use has cast a shadow around the details that most know nothing about. Details that include the major companies are allowed to collect the many forms of input IF you agree, and you do. We all do.
The interesting part is wondering what you look like in terms of the picture that your inputs draw. I believe in Erasing David they called it a mirror. But consider that everything that a user has done while connected to the internet has been stored under a file that can be linked together, site to site, basically creating a map of where and what they have done while on the internet. My assumption is that there is software out there that has the ability to track connections between profiles like Facebook, Twitter, Instagram, etc... and that if a person was important enough this software could gather a portfolio simply label by name that withholds every piece of your information.
Tracking someone's location cannot be very difficult with the right information these days. Heck, most vehicles have GPS tracking which we think is nice for plotting a route to Grandma's but do not realize that it can AND IS used to track the vehicles location. (I wonder if vehicle manufacturers collect data on where we have been?) The cell phone is no different. Perhaps the only difference is that we take our cell phones, which are more like computers than phones, everywhere and is likely to be on our person at all times.  
It's too late, the cat has been out of the bag for a long time. The newest development is going to be the judgments when people see the truth. If an employer discards a resume because the owner's browser history is "unclean" for example. This is the upcoming social shift. Everyone has secrets, it's just about how acceptable they are.
