We are living in an age in which digitization will connect more and more physical assets with IT systems and where IoT endpoints will generate a wealth of valuable data. Companies, individual users, and organizations alike therefore have the need to control their own physical or non-physical assets and data sources. At the same time, they recognize the need for, and opportunity to, share access to such data and digitized physical assets. This paper sets out our technology vision for such sharing ecosystems, reports initial work in that direction, identifies challenges for realizing this vision, and seeks feedback and collaboration from the academic access-control community in that R&D space.

The rapid development of communication and network technologies including mobile networks and GPS presents new characteristics of OSNs. These new characteristics pose extra requirements on the access control schemes of OSNs, which cannot be satisfied by relationship-based access control currently. In this paper, we propose a hybrid access control model (HAC) which leverages attributes and relationships to control access to resources. A new policy specification language is developed to define policies considering the relationships and attributes of users. A path checking algorithm is proposed to figure out whether paths between two users can fit in with the hybrid policy. We develop a prototype system and demonstrate the feasibility of the proposed model.

“…Nowadays, many people use their OSN services on mobile devices, e.g., 80% of Twitter's active users are on mobile 6 . To adapt to this trend, major OSNs add new functionalities to their mobile versions, one of which is location sharing, namely checkin, through mobiles' GPS sensors.…”

“…In [3], access control policies are defined by semantic web technologies. The authors of in [9,2] propose to use hybrid logic as the policy language, this logic has been demonstrated quite powerful and later be used in several works including [22,7,14,17,6,15].…”

In recent years, access control in online social networks has attracted academia a considerable amount of attention. Previously, researchers mainly studied this topic from a formal perspective. On the other hand, how users actually use access control in their daily social network life is left largely unexplored. This paper presents the first large-scale empirical study on users' access control usage on Twitter and Instagram. Based on the data of 150k users on Twitter and 280k users on Instagram collected consecutively during three months in New York, we have conducted both static and dynamic analysis on users' access control usage. Our findings include: female users, young users and Asian users are more concerned about their privacy; users who enable access control setting are less active and have smaller online social circles; global events and important festivals can influence users to change their access control setting. Furthermore, we exploit machine learning classifiers to perform an access control setting prediction. Through experiments, the predictor achieves a fair performance with the AUC equals to 0.70, indicating whether a user enables her access control setting or not can be predicted to a certain extent.
