This book explains strategies, techniques, legal issues and the relationships between digital resistance activities, information warfare actions, liberation technology and human rights. It studies the concept of authority in the digital era and focuses in particular on the actions of so-called digital dissidents. Moving from the difference between hacking and computer crimes, the book explains concepts of hacktivism, the information war between states, a new form of politics (such as open data movements, radical transparency, crowd sourcing and “Twitter Revolutions”), and the hacking of political systems and of state technologies. The book focuses on the protection of human rights in countries with oppressive regimes.
