Keynote: The Power of Community Participation in Shaping Digital Rights Tech [video]
Maria Xynou, Open Observatory of Network
Interference (OONI)Room: ANT-112910:00–11:00Abstract: 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.
