Privacy is a fundamental right recognized by the most important legal instruments for the protection and guarantee of human rights. Privacy by Design, a concept developed in the 1990s by Ann Cavoukian, constitutes both a conceptual and practical development for the defense of that right. We discuss the different views that exist on this discipline from a legal and engineering perspective and put forward the understanding and preliminary conclusions that have been obtained as the result of a research work carried out by a team of doctors in law, security and data scientists and computer engineers. It was of particular interest of this team to incorporate into the research hypotheses the characteristics of the legal normative framework of Latin America and in particular the one of Uruguay.
