Personal privacy, in its various aspects, has occupied human beings since the dawn of mankind. The concept of personal privacy has developed and varied throughout human history.In the last two decades, the privacy issue has never left the public agenda. Privacy, and especially various aspects of personal privacy, have repeatedly been at the center of public discourse. The growing preoccupation with personal privacy stems from the great change [1] Information Communication Technologies (ICT) have brought about in all walks of life in the last two decades. The information revolution hasenabled us totranslate personal privacy into information about personal privacy. Personal privacy can therefore be discussed in terms of personal privacy information.In this article, we will present the fundamental challenges that arise from the fact that personal privacy is information. The challenges can be named: a "physical" challenge that originates from the fact that personal privacy is a kind of order, and every order necessarily goes wrong because of the law of naturethat entropy grows in the world. A challenge arising from the essence of information, whatever information that "wants" to disseminate itself in the world. Challenges originating from the structure of the information network and general and psychological factors that accelerate the dispersion of personal information on the network and thus violate personal privacy.And economic reasons that caused personal privacy information to become a commodity.
