Across social care, healthcare and public policy, enabled by the "big data" revolution (which has normalized large-scale data-based decision-making), there are moves to "join up" citizen databases to provide care workers with holistic views of families they support. In this context, questions of personal data privacy, security, access, control and (dis-)empowerment are critical considerations for system designers and policy makers alike.To explore the family perspective on this landscape of what we call Family Civic Data, we carried out ethnographic interviews with four North-East families. Our design-gamebased interviews were effective for engaging both adults and children to talk about the impact of this dry, technical topic on their lives. Our findings, delivered in the form of design guidelines, show support for dynamic consent: families would feel most empowered if involved in an ongoing co-operative relationship with state welfare and civic authorities through shared interaction with their data.

In our data-centric world, most services rely on collecting and using personal data. The EU's General Data Protection Regulation (GDPR) aims to enhance individuals' control over their data, but its practical impact is not well understood. We present a 10-participant study, where each participant filed 4-5 data access requests. Through interviews accompanying these requests and discussions scrutinising returned data, it appears that GDPR falls short of its goals due to non-compliance and low-quality responses. Participants found their hopes to understand providers' data practices or harness their own data unmet. This causes increased distrust without any subjective improvement in power, although more transparent providers do earn greater trust. We propose designing more effective, datainclusive and open policies and data access systems to improve both customer relations and individual agency, and also that wider public use of GDPR rights could help with delivering accountability and motivating providers to improve data practices.

The abundance of digital content requires cost-effective technologies to extract the hidden meaning from media objects. However, current approaches fail to deal with the challenges related to cross-media analysis, metadata publishing, querying and recommendation that are necessary to overcome this challenge. In this paper, we describe the EU project MICO (Media in Context) which aims to provide the necessary technologies based on open-source software (OSS) core components

Online services have become increasingly centralized, drawing on notions of the ‘platform economy’ to focus on ecosystem value rather than user value. In parallel, there have been efforts by developers to augment these platforms, empowering platform users in the process. We explored a 12-month participatory-action project, focusing on redesigning portions of Just Eat, an online aggregator for takeaway food ordering, building upon theoretical perspectives from public health and Digital Civics. We document our experiences in identifying user behaviours and motivations across multiple design workshops, including the design of a web-augmentation–based template to disrupt platform provider behaviours, empower service users and increase individual agency. Through this case study, we identify opportunities and mechanisms for platform modification, linking augmentation to adversarial design with outcomes that have the potential to improve the well-being of platform users.
