Governments and publicly-funded research institutions increasingly open up data collected and created through research. One way to share and use data obtained through research is through Virtual Research Environments (VREs). Insights obtained through open data use in VREs can subsequently provide input for policy making. However, this process involves many privacy, security and trust issues both for VRE developers and for end-users. We still know very little about what strategies can be used to handle these security, privacy and trust issues. This 1,5 hour interactive workshop aims to discuss and refine strategies for handling privacy, security and trust issues of VREs and their users as developed in the European VRE4EIC project. The workshop will facilitate open discussions making use of the interactive Mentimeter tool to involve all participants in the sharing of practices and in sharing feedback on the strategies.@en
