Discussion with Helen Nissenbaum: How should we think about obfuscation?

Celebrating the 385th anniversary of the University of Amsterdam

11okt2017 17.00 - 18.30


Many of our contemporary privacy worries originate in the large scale generation, collection, storage, analysis, and dissemination of data. When thinking about privacy protection, our natural reflex is to come up with solutions that curtail such data practices. A discussion with a.o. Helen Nissenbaum.

In her recent work, Professor Helen Nissenbaum directs our attention to an altogether different privacy protection strategy called ‘obfuscation’. Obfuscation is defined as “the deliberate addition of ambiguous, confusing, or misleading information to interfere with surveillance and data collection”. Instead of trying to curtail data flows, obfuscation is about the disruption of such flows by adding even more data to them. A great example of obfuscation is the TrackMeNot browser plugin. The plugin automatically and continuously sends search queries to the web browser of your choice. As a result, your own search queries disappear in a sea of fake ones, thus enhancing the privacy of your search queries.

As useful as obfuscation can be for the protection of privacy, it is also criticized. Some liken obfuscation to digital pollution and to free-riding. Moreover, obfuscation could also be used for less laudable aims, like hiding one’s identity when engaging in morally dubious behavior. Given its ability to do both good and bad, how should we think about obfuscation?

The panel consists of Joris van Hoboken, Sarah Eskens, and Marijn Sax. Beate Roessler will act as moderator.
