Abstract
Privacy, the right to an inviolable private life, is one of the most valued and most fragile possessions in modern human society. According to only one of the best-known definitions, privacy is the right to be left alone; the right for every human being to enjoy a space protected by law from arbitrary encroachment, including that of the government. "Every unjustified violation of individual privacy by the state, whatever the means used, must be regarded as a violation of the Fourth Amendment [to the U.S. Constitution—S.S.]," as U.S. Supreme Court Justice Louis Brandeis noted in his famous opinion on wiretapping.1 Privacy is a fundamental human right, and it has been meticulously studied and analyzed. According to one classification scheme,2 privacy can provisionally be divided into four types: privacy of personal data, physical privacy, territorial privacy, and the privacy of communications.
