Billion-dollar fines for Facebook. Cambridge Analytica. Edward Snowden. Apps on our smartphones tracking our every move. Privacy may be a defining issue of our age, but it is also one of the least understood. Our digital world confuses what we know about privacy - what is public, what is private. Do old ethical and legal norms apply to new, digital media? How did the conditions of privacy become so uncertain that we are unsure about our own right to privacy? What can protect us from allowing corporations, governments, hackers and insidious websites to know more about us than we want them to?

Rigorous and engaging, this book examines the minutiae of our digital lives while drawing on a philosophy of ethical and legal frameworks based on the thinking of philosopher Immanuel Kant. With a firm eye on the cutting edge of digital developments, Sacha Molitorisz outlines a robust model of individual consent.

Of urgent importance, this book spells out conceptual and practical steps to ensure our shared future is not dystopian. It shows not only that informed privacy is fundamental to us as individuals, but that in the digital world we need an enforceable regulatory framework to secure our relationships with others and to safeguard our democracies.
