This book presents the latest research on the challenges and solutions affecting the equilibrium between freedom of speech, freedom of information, information security and the right to informational privacy. Given the complexity of the topics addressed, the book shows how old legal and ethical frameworks may need to be not only updated, but also supplemented and complemented by new conceptual solutions. Neither a conservative attitude (âmore of the sameâ) nor a revolutionary zeal (ânever seen beforeâ) is likely to lead to satisfactory solutions. Instead, more reflection and better conceptual design are needed, not least to harmonise different perspectives and legal frameworks internationally. The focus of the book is on how we may reconcile high levels of information security with robust degrees of informational privacy, also in connection with recent challenges presented by phenomena such as âbig dataâ and security scandals, as well as new legislation initiatives, such as those concerning âthe right to be forgottenâ and the use of personal data in biomedical research. The book seeks to offer analyses and solutions of the new tensions, in order to build a fair, shareable and sustainable balance in this vital area of human interactions.
