Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance

Interrogates how digital self-surveillance can be turned against us by police, prosecutors, and political whims

For consumers living in a digitally-connected world, smart technologies have built an inescapable trap of digital self-surveillance. Smart cars, smart homes, smart watches, and smart medical devices track our most private activities and intimate patterns. While these devices allow users to receive personal insights by monitoring their every move, that data can be accessed by police and prosecutors looking to find incriminating clues. Digital technology exposes everyone, everywhere, all at once, and we have few laws to regulate it.

In Your Data Will Be Used Against You, Andrew Guthrie Ferguson warns us of how the rise of sensor-driven technology, social media monitoring, and artificial intelligence can be weaponized against democratic values and personal freedoms. At the same time, that data will solve crimes, radically transforming how criminal cases are prosecuted. Ferguson explores how this proliferation of private data in combination with public surveillance networks promises new ways to solve previously unsolvable crimes, but also leaves us vulnerable to governmental overreach and abuse. He argues for legal interventions that address the threat of digital self-surveillance and provides concrete suggestions about how legislators, judges, and communities should respond.

As consumers, citizens, and potential subjects of surveillance, the questions in this book must be confronted now, before the trap of surveillance captures us completely. Providing a stark warning of the dangers of digital self-surveillance, Your Data Will be Used Against You is a defense of civil liberties against the growing threat of data-driven policing.
