Watch What You Say

After spending the last week talking about packet switching, networks, routers ext, I've begun to wonder about how much of our personal information is just floating around. It's kind of weird to think that every e-mail, Facebook pic, banking transaction has been broken down and disseminated into a decentralized network only to be relocated in one place. How much of that do you think is replicated or possibly sent to several destinations? We have put alot of trust in these technologies and we assume that only sender/reciever will have access. The same assumtion should be applied to cell phones. How private are they really? We know from Hollywood movies that criminals and terrorists can be tracked but what about the average network user? With the excessive use of cell phones today we have become obsorbed by an invisible dome of service and survailence. I have a hunch that the iPhones GPS capabilities work both ways, maybe all cell phones have GPS chips and if that was the case anyone of us could be tracked by whoever had access to the technology. Don't worry I'm not suffering from paranoia ( I think), it's just an issue that I have been pondering. I know that accidentally clicking "reply to all" when you don't mean to is bad enough, but having all of your personal info bouncing around a global network on a daily basis is kind of worrysome.
