“…In community-centered systems, multiple members can contribute to the creation and management of resources, being data or any other object [Damen and Zannone 2013;Hu et al 2013]. The collabora-0:5 tive management of shared resources has a significant impact on their protection.…”

“…This issue is further aggravated by the functionality for information sharing and community building provided by many existing community-centered systems (e.g., tagging). While promoting information sharing, these functionalities can lead to a disclosure of information that is unforeseeable and unexpected by users [Damen and Zannone 2013;McLaughlin and Vitak 2012], who can sense it as a lack of control over their information.…”

“…A typical example of such capabilities is the tagging feature provided by Facebook. It has been shown that tagging could increase the visibility of tagged objects beyond users' expectations [Damen and Zannone 2013;Pesce et al 2012;Wisniewski et al 2015]. In order to deal with these concerns new solutions that allow the understanding of the consequences of enforcing (possible conflicting) protection requirements on shared resources are needed.…”

“…Within collaborative environments, several entities can be involved in the creation, management and protection of sensitive resources [Damen and Zannone 2013;Hu et al 2013;Mazurek et al 2014]. For instance, in social network websites data can be posted by one user, can be hosted in the profile of some other user, and refer to yet other users.…”

“…As a consequence, several research efforts have focused on the design of novel models and mechanisms able to provide fine-grained control over the access and usage of sensitive resources shared in these environments. In particular, much attention has been placed on access control issues in the social computing domain, wherein a large amount of personal content is often shared among users (e.g., Carminati et al 2009;Damen and Zannone 2013;Hu et al 2013;Squicciarini et al 2010;Xiao and Tan 2012;Rajtmajer et al 2016;Vishwamitra et al 2017]).…”

Survey on Access Control for Community-Centered Collaborative Systems

The last decades have seen a growing interest and demand for community-centered collaborative systems and platforms. These systems and platforms aim to provide an environment in which users can collaboratively create, share and manage resources. While offering attractive opportunities for online collaboration and information sharing, they also open several security and privacy issues. This has attracted several research efforts towards the design and implementation of novel access control solutions that can handle the complexity introduced by collaboration. Despite these efforts, transition to practice has been hindered by the lack of maturity of the proposed solutions. The access control mechanisms typically adopted by commercial collaborative systems like online social network websites and collaborative editing platforms, are still rather rudimentary and do not provide users with a sufficient control over their resources. This survey examines the growing literature on access control for collaborative systems centered on communities, and identifies the main challenges to be addressed in order to facilitate the adoption of collaborative access control solutions in real-life settings. Based on the literature study, we delineate a roadmap for future research in the area of access control for community-centered collaborative systems.

As social networks, shared editing platforms and other collaborative systems are becoming increasingly popular, the demands for proper protection of the data created and used within these systems grows. Yet, existing access control mechanisms are not suited for the challenges imposed by collaborative systems. Two main challenges should be addressed: collaborative specification of permissions, while ensuring an appropriate levels of control to the different parties involved, and enabling transparency in decision making in cases where the access requirements of these different parties are in conflict. In this paper we propose a data governance model for collaborative systems, which allows the integration of access requirements specified by different users based on their relation with a data object. We also study the practical feasibility of enabling transparency by comparing different deployment options for transparency in XACML.
