If you’ve listened to even a handful of my shows, you are well aware that you’re being tracked around the web. But even I was surprised by some of the things I learned in the recent white paper from the Electronic Frontier Foundation entitled “Behind the One-Way Mirror: A Deep Dive Into the Technology of Corporate Surveillance”. One of the prime authors of this report, Bennett Cyphers, came on my show to walk us through the myriad and shocking ways that ad tech companies have found to identity us as we surf the web, use our smartphones, and even walk around the real world.

Bennett Cyphers is a staff technologist on the Tech Projects team at the Electronic Frontier Foundation (EFF). He contributes to a variety of different projects within EFF, most of them tied to privacy and competition. In the past year, he’s worked on the tracker-blocking browser extension Privacy Badger, provided technical advice to lawyers and activists, and read and re-read the California Consumer Privacy Act. Before coming to EFF, he was a policy intern at Access Now and earned a Master’s degree for work on privacy-preserving machine learning. In his spare time he designs t-shirts for fake punk rock bands.
