Helen Nissenbaum, a philosopher, is a professor at Cornell Tech and in the Information Science Department at Cornell University. She is director of the Digital Life Initiative at Cornell Tech, which was launched in 2017 to explore societal perspectives surrounding the development and application of digital technology. Her work on contextual privacy, trust, accountability, security, and values in technology design led her to work with collaborators on projects such as TrackMeNot, a tool to mask a user's real search history by sending search engines a cloud of ‘ghost’ queries, and AdNauseam, a browser extension that obfuscates a user’s browsing data to protect from tracking by advertising networks.

Building on such projects, in 2015, she coauthored a book with Finn Brunton called Obfuscation: A User’s Guide for Privacy and Protest. The book detailed ideas on mitigating and defeating digital surveillance. With concerns about surveillance surging in a time of rising authoritarianism and the advent of powerful artificial intelligence technologies, Justin Hendrix reached out to Professor Nissenbaum to find out what she’s thinking in this moment, and how her ideas can be applied to present day phenomena.
