Privacy
Appearance
Privacy is the ability to function in society anonymously.
According to Eric Hughes (quoted in http://www.activism.net/cypherpunk/manifesto.html), "Privacy is the power to selectively reveal oneself to the world."
Some ways in which privacy is lost include the following:
--Waiver of privacy right included in the terms of a contract.
--Theft of confidential information.
Some methods which have been used to defend privacy include the following:
--Non-transparent packages
--De jure establishment of privacy rights
