Keynote: The Power of Community Participation in Shaping Digital Rights Tech

Maria Xynou, Open Observatory of Network Interference (OONI) Room: ANT-1129 11:00–12:00 Abstract: Control of the internet—such as online surveillance or internet censorship—is a political issue, warranting a political response. The nature of internet control varies from country to country, requiring different responses from communities on the ground. Decentralization, PETs and free and open source software (FOSS) are important means to fight back, but it's also important to engage impacted communities in the design and creation of such technologies to ensure that their needs are met. Through examples from OONI's community-driven approach to global censorship measurement, this talk will share how and why there is power in involving communities from around the world in shaping digital rights protecting technology. Bio: Maria Xynou co-leads the Open Observatory of Network Interference (OONI), a non-profit, free software project measuring internet censorship globally. Since 2016, Maria has published more than 60 reports documenting internet censorship around the world, and has led global OONI community engagement efforts on censorship measurement. Previously, Maria worked with Tactical Tech on investigating the data industry, creating privacy and digital security resources, and facilitating digital security workshops for human rights defenders. Maria also worked with India's Centre for Internet and Society (CIS) on investigating surveillance in India and volunteered with Privacy International.
