What are the implications of a data-driven society?

In the wake of the scandal involving Cambridge Analytica, and as Europe prepares to grapple with new data protection legislation (GDPR), researchers, advocates and technology experts are meeting at Cardiff University to discuss what the pervasive collection and use of people's personal data means for democracy and social justice. More than 200 international experts are attending the first ever 'Data Justice' conference to share knowledge on how both public authorities and private businesses collect, analyse and use the data of citizens, and discuss solutions for the challenges of the 'datafication' of society. "The misuse of personal data to influence elections, but also the increasing application of data analytics and algorithmic decision-making in the public sector, show that the use of and control over data has become a key question of our time," said Dr Arne Hintz, one of the conference organisers and co-directors of Cardiff University's Data Justice Lab which is hosting the event. "As digital citizens, we are increasingly profiled and categorised according to the data we produce, and our future lives are heavily impacted by this. Many cases of discrimination and wrongful assessments through data have been documented, and we need to have a better understanding of the implications for society," added Dr Lina Dencik, conference co-organiser and co-director of the Data Justice Lab. The conference has generated international attention, raising participant numbers far above what the organisers expected, with participants arriving from around the globe, including the US, India, Australia and South Africa.
