Technology challenges for privacy: the case of decentralized social media

UA2.220 (Guillissen)
Cristina DeLisle
As decentralized social media gathers more users, the privacy by design and default principles from the GDPR are in accordance to the design model it proposes. This talk is going to tackle the main advantages and challenges this approach brings, from the perspective of the data protection legislation and privacy architectural strategies.

Social media platforms have been a central feature in our generation and as we grow more toward understanding their power and taking part in their evolution, we realize the challenges they impose. One of those is how to protect personal data of users, and ensure that the processing is done in accordance with legislation such as GDPR. Decentralized social media has developed as a space where personal data ownership is a priority, coming as an alternative to centralized platforms. Not coincidentally, they are mostly open source software, as transparency and offering control of the data to the users go hand in hand with this ambition. Blockchain based social media networks, and projects built on top of the ActivityPub protocol are some of the most popular examples of alternatives which have gathered significant numbers of users or data subjects, under the GDPR. One of the main architectural strategies in building software which is privacy by default and design is data separation. It states that the processing of personal data should be performed whenever possible in a distributed manner. As the GDPR lists privacy by design and default as core principles, decentralized social networking poses a significant advantage compared to centralized solutions. One heuristic to take from this is if the future is privacy-oriented, then social media will be decentralized. This talk is going to offer an analysis of the main benefits and challenges that decentralized social medial pose, from the points of view of personal data protection legislation and privacy design patterns for software architecture.

In a perfect world, lawyers (and the entire legal system) should not be necessary. And in a perfect FOSS world, everyone respects each and every provision of every license. The reality is, however, very different, and enforcement may be a necessary evil. This need does not mean we have to open the gates to be flooded by "copyleft trolls", but to establish a sound enforcement policy, in order to unleash the lawyers only for the most blatant and repeated violations

Projects today often have thousands of FOSS dependencies. Since risk flows downstream in the supply chain; projects inherit and pass on the risks of all their dependencies. In response, licensing bill of materials tools often seek to push well-formed licensing inventory data upstream in an effort to ease downstream compliance challenges. At the same time, there has been a stark increase in license violations, especially, though not exclusively, on copyleft licenses. Is this approach to improving ...

How can we give users standing in free/open software/hardware? How can we motivate end users to care about FOSS if they can't express their preference? What tools do we have beyond the "court of public opinion"? Can we invent a NEW legal hack?

Photography policies have begun to appear at free-software events in recent years. These policies typically seek to address personal privacy concerns for event attendees, but they sometimes conflict with the event's desire to record talks, Q&A periods, and social gatherings in public spaces. If not drafted with care, photo policies also run the risk of creating ambiguities for journalists, other attendees making personal photo or video recordings, and members of event-hosting organizations or ...

We have seen several licenses proposed as "open source" that carry some obligation or restriction related to ethics or other social goals. Is this a good direction for FOSS license drafting?
