Trust, Mr. Schneier writes, is the glue that binds our societies. Over centuries we have invented various means of ensuring it: moral codes, reputation within a certain community, laws and of course security tools, from embankments, the most primitive kind of defense, to facial-recognition technology.
The liars he worries about most these days are not cyberwarriors or even cybercriminals but private companies and government agencies advancing their own interests, whether for surveillance or commerce. Apple controls the memory on our iPhones. Google keeps tabs on what we search for, and whom we write to, when we use Gmail. We unknowingly pledge allegiance to the companies we do business with.
