There are various facets of privacy, not all related to modern technologies. For example, among the issues that have been debated in many countries are whether it is legal to take pictures or videos of other people in public, how your medical records are handled and so on. However, the most important privacy issue today is the gathering of online data for the creation of personally identifiable information that can then be used for commercial or other purposes.
