Law of the United States
Even though the right to privacy is not explicitly stated in many constitutions of sovereign nations, many people see it as foundational to a functioning democracy. In general the right to privacy can be found to rest on the provisions of "habeas corpus", which first found official expression under Henry II in 11th century England, but has precedent in Anglo-Saxon law. This provision guarantees the right to freedom from arbitrary government interference, as well as due process of law. This conception of the right to privacy is operant in all countries which have adopted English common law through Acts of Reception. The Law of the United States rests on English common law by this means.
