Data and Goliath is the new book from security expert Bruce Schneier has a new book out on the importance of information security and privacy in the digial age. It looks like an interesting read. There was a short overview of the idea of the book in Data & Goliath’s Big Idea
Data and Goliath is a book about surveillance, both government and corporate. It’s an exploration in three parts: what’s happening, why it matters, and what to do about it. This is a big and important issue, and one that I’ve been working on for decades now. We’ve been on a headlong path of more and more surveillance, fueled by fear–of terrorism mostly–on the government side, and convenience on the corporate side. My goal was to step back and say “wait a minute; does any of this make sense?” I’m proud of the book, and hope it will contribute to the debate.
But there’s a big idea here too, and that’s the balance between group interest and self-interest. Data about us is individually private, and at the same time valuable to all us collectively. How do we decide between the two? If President Obama tells us that we have to sacrifice the privacy of our data to keep our society safe from terrorism, how do we decide if that’s a good trade-off? If Google and Facebook offer us free services in exchange for allowing them to build intimate dossiers on us, how do we know whether to take the deal?
There are a lot of these sorts of deals on offer. Waze gives us real-time traffic information, but does it by collecting the location data of everyone using the service. The medical community wants our detailed health data to perform all sorts of health studies and to get early warning of pandemics. The government wants to know all about you to better deliver social services. Google wants to know everything about you for marketing purposes, but will “pay” you with free search, free e-mail, and the like.
Here’s another one I describe in the book: “Social media researcher Reynol Junco analyzes the study habits of his students. Many textbooks are online, and the textbook websites collect an enormous amount of data about how–and how often–students interact with the course material. Junco augments that information with surveillance of his students’ other computer activities. This is incredibly invasive research, but its duration is limited and he is gaining new understanding about how both good and bad students study–and has developed interventions aimed at improving how students learn. Did the group benefit of this study outweigh the individual privacy interest of the subjects who took part in it?”
Again and again, it’s the same trade-off: individual value versus group value.
