The proposed dynamic access control model is based on description logic (DL) augmented with a default (δ) and an exception ( ) operator to capture context features. Currently, this model has an expressivity almost comparable to OrBAC system (OrBAC (Organization Based Access Control) has been formalized in first order logic), all features needed for real attribution of authorization, i.e., assigning authorization to a user according to its role in an organization in a given context. A notable difference of our model is the allowing of composed context, the addition of new context and the deduction of new authorization depending on context.

“…us, access to OSNs is subject to user-specified policies. Access control systems used in IoT are RBAC (role-based) [21], organization-based (Or-BAC) [22], trust-based [23], capability-based (CapBAC) [24,25], and attribute-based access control (ABAC) [26,27]. In a centralized access control system, rights are assigned by a centralized entity that turns out to be a failure [28].…”

In recent years, online social networks (OSNs) have become an essential part of our social life. In OSNs, users can post resources to predefined groups of users, for example, family, friends, close friends. However, due to these predefined groups of users, few irrelevant users may get access to these published resources. Moreover, the users cannot configure privacy settings due to the lack of technical knowledge and the rigidity of the access control management system. To tackle these issues, we propose a text-based dynamic and fine-grain access control system for OSNs. Our proposed model uses a dynamic clustering algorithm to create user clusters based on the mutual interests of the users. After clustering, the proposed system creates automatic access rules based on the relationship between the users’ clusters and their resources. The proposed system will ensure fine-grained access control and automatic assignment of policies to the text-based resources. We have implemented our system to gauge the applicability, and the results are discussed in the experiments section.

The proposed access control model is based on description logic (DL) augmented with a default (δ) and an exception ( ) operators to capture context feature. Our model is inspired from OrBAC model and has an expressivity almost comparable to it, which means assigning authorization to a user according to its role in an organization in a given context. The most important difference of our model is the allow of composed context, the add of new context and the deduction of new authorization depending on context.
