Social networks have created a plethora of problems regarding privacy and the protection of personal data. The use of social networks has become a key concern of legal scholars, policy-makers and the operators as well as users of those social networks. This pathbreaking book highlights the importance of privacy in the context of today's new electronic communication technologies as it presents conflicting claims to protect national and international security, the freedom of the Internet and economic considerations. Using the New Haven School of Jurisprudence's intellectual framework, the author presents the applicable law on privacy and social media in international and comparative perspective, focusing on the United States, the European Union and its General Data Protection Regulation of 2018 as well as Germany, the United Kingdom and Latin America. The book appraises the law in place, discusses alternatives and presents recommendations in pursuit of a public order of human dignity.
