The protection of fundamental rights is increasingly relevant in the digital age. The massive spread of digital and algorithmic technologies raises inherently constitutional questions. Rights and freedoms are exposed both to opportunities and challenges of digital technologies, thus leading to different constitutional responses. This book offers an overview of the most important challenges posed by the rise of cyberspace from a legal standpoint. After some preliminary chapters on the Internet landscape, it focuses on how the advent of digital technologies has impacted content and data, thus exploring the effects in terms of protection of freedom of expression, the right to privacy and data protection. By addressing these topics, this book aims to provide readers with a background to understand the constitutional issues raised by digital technologies.
