Rapid and radical digitalization and the “fourth industrial revolution” are generally associated with progress, but also pose significant risks to privacy rights and democracy. This article proposes a public law reading of the South African Constitution to respond to the dangers posed by disruptive technological change, in light of the constitution's rights-orientated and rule-of-law-centred approach to interpreting the right to privacy. It examines the legal resources available in the South African legal system and, specifically, its constitution. The article emphasizes the way South African privacy jurisprudence infuses the right to privacy with the value of dignity, and how this allows an interpretation that sees privacy as a public, as well as private, right. The article concludes that this rights jurisprudence, alongside the constitutional principles of proportionality, subsidiarity and supremacy, has established a working foundation to articulate the right to privacy in a way that is suitable in the digital age.
