The book starts by exploring boundaries of international privacy law in upholding privacy and data protection in the digital ecosystem where threats to privacy are increasingly transnational, sophisticated and privatized. It then explores the potential of global privacy initiatives, namely Internet bills of rights, universalization of regional systems of data privacy protection, and the multi-level privacy discourse at the United Nations, in reimagining the normative contours of international privacy law. Having shown limitations of global privacy initiatives, the book proposes a pragmatic approach that could make international privacy law better-equipped in the digital age.
