Using the Internet often means you leave a trail behind you. This is part of life in the digital age. Every time you use a credit card you create a record in several computers. Other computers may be storing information about you such as your medical history, driving record, tax filings and so on. This means citizens in the digital age should know their rights.
Many governments already have laws to protect private information.
For example, the US has many laws restricting access to sensitive information such as medical and credit records. You might be surprised to know Hungary passed a law in 1991 to prevent misuse of information associated with the national identity card. Yet the growth of new technologies is outpacing legislation. Cellular phones and satellite navigation systems can report the locations of their users. It's not difficult to imagine how these and other technologies could be abused.
