RELATIONSHIP BASED INFORMATION SHARING CONTROL SYSTEM AND METHOD OF USE

摘要

User-to-user (U2U) relationship-based access control has become the most prevalent approach for modeling access control in online social networks (OSNs), where authorization is typically made by tracking the existence of a U2U relationship of particular type and/or depth between the accessing user and the resource owner. However, today's OSN applications allow various user activities that cannot be controlled by using U2U relationships alone. Disclosed herein is a relationship-based access control model for OSNs that incorporates not only U2U relationships but also user-to-resource (U2R) and resource-to-resource (R2R) relationships. Furthermore, while most access control approaches for OSNs only focus on controlling users' normal usage activities, disclosed herein is a model that also captures controls on users' administrative activities. Authorization policies are defined in terms of patterns of relationship paths on social graph and the hopcount limits of these paths.
