Is Privacy An Illusion?

Every phone number appears in a database. Everyone of your favorite web site keeps track of your computer. With many other factors, our privacy is under a invisible threats. Sometimes, our privacy could be invaded by others through the use internet. Since now we are living in a global community, not everyone know your name, your social ID number, or even your phone number. Through some of the browser and other online program people can "stock" you. Skype, Facebook, Twitter, or even online shopping website could let other people stock you. In today modern society, I think our privacy is at risk, since there are so many hacker around the world right now. Personally, I think my privacy is at risk because people might be reading or tracing my computer ID now. Until now, the companies have not develop a program that can effectively block the outside intruder when they are trying to hack in for someone's privacy. Concerned that the physical safety of individuals, it is important for everyone to protect their own privacy.
