The right to privacy is enshrined in the U.N.'s Universal Declaration of Human Rights. How it is implemented member states of the UN is of course up for discussion, as is the balance between individual rights and the collective good with regards to the degree the state or other organised entites has the right to interfere with one's privacy. In terms of living life, we should assume little privacy, in a sense this places us on the path towards behaving impeccabbly within every moment.
