'Person of Interest': Cell phones spying on you

Tech Industry
-If I told you that on you right now there's a 2 way multi platform automatic wireless surveillance device, you might not be real happy about that, but don't be too upset because you signed up for it when sign up for a smart phone and that's a key reality on the new CBS show person of interest. -You smart phone has GPS to know where you are, memory to keep records of what you did on it all day and 3G and Wi-Fi to send that information to Facebook, Google, Apple, Microsoft, and other companies. Without even knowing it, you leave an amazing crumb trail of information about yourself. -If you have a phone and has Wi-Fi and has Bluetooth and it's on all the time, it's very simple for people to take advantage of that to turn your phone into a spy that you take with you everywhere. -And that is one of the key battles in the real world. Who has the right to the information and when. -The programs seem to delete has a relevant numbers. Now, you're trying to save them. -I said, I tell you the truth. -While privacy policy sorts out, there are some things you can do. Get familiar with the location settings on your phone. For example, do you want your pictures tagged with place and time you took them? Do you want all your apps to have access to your GPS location? You can often switch that off, but know that 911 operators will always see where you are if you call from a cellphone and look at the settings for all your apps like Facebook that often have their own location privacy settings. Taking these steps can help keep smart surveillance more on TV and less in your life for now. In San Francisco, I'm Brian Cooley, CNET.com for CBS news. -I'm sorry I haven't called I think-- -I understand.
