Survey on Access Control for Community-Centered Collaborative Systems

Abstract

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.

Recommendations to Enhance Privacy and Usability of Smart Toys

“…Although the FTC continues to levy hefty fines against companies violating COPPA, adopting effective privacy controls remains a challenge in the field [13]. To address this challenge, we sought to review the main security vulnerabilities of some current smart toys and their resulting user privacy concerns and impact.…”

Access control technologies for Big Data management systems: literature review and future trends

“…Finally, a policy analysis framework is also required for community centered collaborative systems, such as online social networks and collaborative editing platforms, which may be seen as federated applications that handle Big Data. Recent surveys pointed out that these systems typically provide rudimentary forms of access control (Paci et al 2018). A key requirement for access control models tailored for collaborative systems is to allow users to understand collaborative decisions, as well as to inspect users access preferences, and to evaluate their effects (Paci et al 2018).…”

Therefore, the definition of a reasoning framework capable of operating within such federated environments with multiparty access control models appears as a research challenge of paramount importance.…”

Trust and Privacy in Knowledge Graphs

“…There are many definitions for privacy -see for example [31]; [24][33] present surveys on multi-party privacy. Tavani [35] classified privacy theories into four broad types: the nonintrusion, seclusion, limitation, and control theories.…”
