Online Social Networks (OSNs) have an infamous history of privacy and security issues. One approach to avoid the collection of massive amounts of sensitive user data at a central point is a decentralized architecture.
An event invitation feature - allowing a user to create an event and invite other users who then can confirm their attendance - is part of the standard functionality of OSNs. Implementing this feature in a Privacy-Preserving Decentralized Online Social Network (DOSN) is non-trivial because there is no fully trusted broker to guarantee fairness to all parties involved.
In this work we look into decentralized protocols for implementing event invitation features. We formalize possible security and privacy properties of such a feature and propose a secure implementation allowing different types of information related to the event (e.g., how many people are invited/attending, who is invited/attending) to be shared with different groups of users (e.g., only invited/attending users).
The results can be applied in the context of Privacy-Preserving DOSNs, but might also be useful in other domains such as Collaborative-Working Environment (CWE) and their corresponding collaborative-specific tools (i.e., groupware).
