The fundamental concept of Privacy is something universally understood by everyone. The right to be left alone, without interference or intrusion is documented in Article 12 of the ‘The United Nations Universal Declaration of Human Rights’ (1948):
Put simply, we are constantly under surveillance: constantly tracked, targeted, profiled, and exploited, sometimes willingly (without consciously realising it)
‘No one shall be subjected to arbitrary interference with his privacy, family, home, or correspondence, nor to attacks upon his honour and reputation. Everyone has the right to the protection of the law against such interference or attacks.’ (1)
