Big Data - Big Security Problems?

Companies, public organisations and intelligence services collect huge amounts of data at an ever increasing speed. This holds great promise for the services we can expect from computer systems but also raises questions from a security and privacy point of view.

In the talk, Ivan Damgård will shed light on some of the stories told about the subject and try to distinguish myth from reality. For instance: Is there always a good reason to collect data? Are our identities and personal data safe on the Internet? Do we have any privacy left out there? Should we care? If yes, what can we do about it?

Ivan Damgård is a professor of Computer Science at Aarhus University and director of the Center for research in the Foundations of Electronic Markets (CFEM), supported by the Danish Strategic Research Council. Damgård’s research is focused on cryptologic methods for protection of data, more specifically he has obtained a number of fundamental results on secure distributed computing. Damgård is a fellow of the International Association for Cryptologic Research (IACR) and the Editor in Chief of the Journal of Cryptology. He is also a co-founder of the companies Cryptomathic and Partisia.­



Case Presentations


Big News: Exploring Newspaper Archives and How People Use Them

Jens Funder Berg, Visiolink; Tonny Skovgård Jensen, National Library

Today's news as well as old news from newspapers are being compiled into huge digital newspaper archives these years. These archives are a new source for research that is yet to be explored. In this case Visiolink will present how they process tens of thousands of new pages each day, delivering digital versions of more than 700 European newspapers and magazines, and how the log files can be analyzed using business intelligence tools. The State and University Library will present their mass digitization project which will digitize 32 million historical newspaper pages in the next 3 years.  Furthermore we will give a few examples of research based on huge newspaper archives. 





Opening Up Municipal Data 

Torben Glock, City of Aarhus; Martin Brynskov, AU

Cities generate and process immense amounts of data, from sensors around the city, to plans and interactions with citizens. Much of this data resides in separate legacy systems and are not easily accessible for analysis, use and inspection. The reason is sometimes technical, sometimes legal or even ethical in nature. Working with Aarhus University, the City of Aarhus has over the years begun to turn this multitude of challenges into a resource for planning and producing the conditions for better lives between the systems, together with its citizens.



Measuring impact across social media 

Anne Jensen, NorthSide Festival; Anja Bechmann, AU

Social media plays an increasingly important role in cultural events worldwide. At concerts and festivals you often see participants with smartphones in the air to document the event. These digital footprints of the participants create a large digital social layer that connects to the event. The research project ‘Measuring impact across social media’ seeks to develop methods and software to improve the collection and analysis of such data to account for structures and patterns in the usage of social media across platforms.



Teledialogue Between Social Workers and Children Placed in Foster Care or at Institutions

Stinne Højer Mathiasen, Herning Municipal; Lars Bo Andersen, AU

Danish children placed in foster care or at institutions are under the formal custody of social services departments. Accordingly, these departments collect a wide array of data on the children, which they manage through case management software. However, the children themselves do not partake directly in this continuous data collection. Rather, their dealings with social workers is often limited to biannual meetings and, in addition, mediated by pedagogues or other adults. On this backdrop, the research project: Teledialogue seeks to develop improved and continuous communication between social workers and children through chat and video conferencing software.
