Call For Papers

Sharing (in) a Digital World

Our future is shared. The Internet and the web, (personal) data, resources, climate effects, music, genetic information, trading routes, celestial bodies, holiday homes, rides: we have built a globalized world on sharing, and sharing will be the great protagonist of our future. However, sharing is mostly realized through centralized platforms, controlled by dominant industry players, instead of decentralized architectures and communities. Recently, European policymakers have started to provide legal frameworks for sharing, including concepts such as data intermediaries and data sharing obligations.

Experts can work to make sharing secure, safe, and just, to protect the privacy and other rights of those who want to share, and of those who cannot or do not want to. Starting today, the experts of tomorrow can research ways to enable the fair distribution of the benefits – and side-effects – of sharing in a globalized world. How can sharing be realized using today’s technology and building blocks, but with a sustainable and inclusive approach for the shared IT worlds and metaverses of the future? On a structural level, who determines who is – purposefully or carelessly – included in and excluded from accessing, sharing, or deciding, and which narratives are used to justify these positions? How can we address the sharing paradox, i.e. that everyone wants to see what others shared, but people are reluctant to sharing their own information? Which of the technical and organisational approaches to sharing are best suited to protect the rights and freedoms of natural persons?

These questions and issues in the context of privacy and identity management are still nascent. The summer school aims to create a platform for spreading awareness and facilitating interactions and knowledge exchanges around these issues.

The 18th IFIP Summer School on Privacy and Identity Management takes a holistic approach to society and technology. We support interdisciplinary research exchange and foster discussions through keynote lectures, tutorials and workshops. Participants will benefit from presenting their research and receiving meaningful feedbacks. The summer school culminates in the publication of selected papers among those submitted by the participants, in the form of an edited volume published by Springer.

We welcome contributions combining any of the following perspectives:

sociological, legal, technical, ethical, political, surveillance, intersectional, anthropological, economic, historical, media & communication, regulatory, philosophical, critical, disabilites, and psychological studies in the areas around privacy, data protection, and identity management.

The IFIP Summer School encourages not only interdisciplinarity but also broader diversity. It particularly welcomes submissions on how to foster gender and cultural balance in privacy and identity research and policy, and notably tutorials and workshops about how to raise awareness in these matters.

Paper Submission and Review Process

The research paper presentations focus on involving students, and on encouraging the publication of high-quality, thorough research papers by students and young researchers. To this end, the school will have the following process for submissions:

  • Submit an extended abstract of at least 2 and at most 4 pages in Springer LNCS style. From these submissions, the PC chairs select papers within the scope of this call for presentation at the summer school.
  • A full length submission (up to 16 pages), also in Springer LNCS format, is required to be submitted before the summer school by applicants whose abstract has been accepted. The full-length paper will be published in the pre-proceedings.
  • At the summer school each author will give a presentation followed by a discussion. 
  • After the summer school, authors are invited to submit to the proceedings (again 16 pages LNCS). It is expected that they take into account the comments and discussions from the summer school.
  • There will be a review of these submissions by the Programme Committee. Based on these reviews, papers might be accepted, conditionally accepted, or rejected.
  • Accepted and (after satisfactory revision) conditionally accepted papers will be included in the summer school’s proceedings, which will be published by Springer.

Proposals for Workshops and Tutorials

A workshop is an interactive session that is scheduled for one or two hours and focusses on involving students in discussion. In it, participants jointly work on a topic or project that is related to the theme of the summer school. Workshop actitivies are summarized in short papers that recapitulate the outcome and the kinds of discussion raised in the summer school, for inclusion in the proceedings. Proposals for workshops should contain a 2-page statement presenting the topic and summarising the planned activity and the expected contributions from the audience members, e.g. responding to a questionnaire or conducting a small experiment. Proposers should indicate whether any special equipment is needed for the workshop, such as audio-visual systems or computational equipment and support.

Tutorials are one or two hour long presentations. They should deal with topics that are of interest for the interdisciplinary audience in the summer school. Tutorials should provide knowledge on theoretical, empirical, methodological, practical or other aspects relevant for the summer school. Proposals for tutorials should contain a 2-page summary and state the level and background required for audience members to follow the tutorial.

A course certificate for 1,5 ECTS can be granted for students who attend the summer school and write a short essay on how their own research is relevant in relation to or can be inspired by the summer school sessions. A course certificate for 3 ECTS can be granted for students who attend the summer school, submit and present an abstract for a research article, and demonstrate that they have addressed the feedback from the summer school in an extended version or rebuttal. We encourage submissions from students from emerging economies: it is possible to apply for support from the IFIP Digital Equity Fund to ease student travel.

We meet at Ekebergrestauranten at 19:00 for the summer school dinner (in the room named “Store Festsal”). The restaurant’s address is Kongsveien 15, 0193 Oslo, Norway (see map), and you can easily reach it via the tram stop Ekebergsparken (from the city center take the tram line 13 towards “Ljabru” or line 19 towards “Ljabru” or “Bråten”). The dinner is included in the conference fee, including some drinks.

For those interested, there is a sculpture park next to the restaurant, so it might be a good idea to arrive 30-60 minutes early and have a stroll.
