Bruce Schneier, who coined the term "Security Theater" to describe the TSA, has published another book, titled "Data and Goliath".
From "Cryptogram", his monthly newsletter -
After a year of talking about it, my new book is finally published. This is the copy from the inside front flap:
You are under surveillance right now.
Your cell phone provider tracks your location and knows who's with you. Your online and in-store purchasing patterns are recorded, and reveal if you're unemployed, sick, or pregnant. Your e-mails and texts expose your intimate and casual friends. Google knows what you're thinking because it saves your private searches. Facebook can determine your sexual orientation without you ever mentioning it.
The powers that surveil us do more than simply store this information. Corporations use surveillance to manipulate not only the news articles and advertisements we each see, but also the prices we're offered. Governments use surveillance to discriminate, censor, chill free speech, and put people in danger worldwide. And both sides share this information with each other or, even worse, lose it to cybercriminals in huge data breaches.
