OK, we talk about facial recognition a lot here on the 4cast. We wouldn't blame you if you suspected we were a little obsessed. But when I caught a random news article about how researchers at University of Chicago have developed a tool—called "Fawkes" in honor of the Guy Fawkes masks sported by protesters—which disrupts the systems that build facial recognition systems, I was intrigued, and it led me into the larger field of data poisoning.
