Abstract: Collaborative systems deal with shared content which is jointly owned and managed by multiple users. Individual privacy preferences should be taken into account during access control evaluation, resolving conflicts while ensuring the acceptability of collective access decisions. In this work we propose a threshold-based conflict resolution strategy in the context of social networks. The resolution method is based on the information captured in the social graph, supporting the interpersonal relations between users, and the provenance graph, supporting the multi-management of data. A prototype implementation attests the feasibility of the proposed approach.
