It used to be that a city was more private than a village, not because nobody could see what you were doing but because nobody could keep track of what everybody was doing. That sort of privacy cannot survive modern data processing. The computer on which I am writing these words has sufficient storage capacity to hold at least a modest amount of information about every human being in the U.S. and enough processing power to quickly locate any one of those by name or characteristics. From that fact arises the issue of who has what rights with regard to information about me presently in the hands, and minds, of other people.
