digital privacy

The privacy is used frequently in ordinary language as well as in philosophical, political and legal discussions, yet there is no single definition or analysis or meaning of the term. Digital technology and the internet have made new threats possible. For example, computer chnologies database, digital cameras, the Web - have profoundly changed what people can know about us and how they can use the information. The first step of protecting privacy is that people have to understand the risks and problems of digital technology. In privacy, there are three key aspects:

1. freedom from intrusion- being left alone
2. control of information about oneself
3. freedom from surveillance
None of these concerns are absolutem, they may need tobe balanced against other concerns, such as publicsafety.

As technology, specifically the internet, takes off, issues of privacy are critically important. For
example, Should Google be allowed to take pictures of people's houses? What happens if someone takes a picture of a private citizen and posts it on the internet? What happens if it is a video?

The formulation of privacy is negative right. The reason is that the important of privacy is protected information, such as bank account, social security, passport, etcs, from other people. These information stored in database and frequently update the information.
