“…However, as the collaboration spaces interconnect to form a distributed network, access control techniques are being more fine-grained and hierarchical. Catering to diverse network environments, different models like Trust Based Access Control [5], Attribute Based Access Control [6] and Task Based Access Control [7] have been widely used.…”

Access control in 3-D virtual reality systems is a wide and still growing topic. A good access control model is a premise for data security, and makes the whole system play its functions reliably. We compare access control techniques in 3D system OpenSim with that of other virtual reality systems. By using a general extended scheme, we analyze the model and the rule of access control in OpenSim. In this scheme, we provide a method of expanding network services for special proposes. Meanwhile, it verifies the feasibility of developing OpenSim's services on the basis of data security.

“…In order to better cater for use case scenarios that involve data sharing across various distributed data stores underpinning decentralized applications, there is a need for tools and technologies that are not only capable of working with distributed data but are also able to manage data resources that come with a variety of usage terms and conditions specified by data producers. However, the vast majority of decentralized web initiatives, which aim to provide users with a greater degree of control over personal resources, manage data access via simple access control mechanisms (Tran et al, 2005;Toninelli et al, 2006;Ouaddah et al, 2016) that are not able to verify that usage conditions are adhered to after access has been granted (Akaichi and Kirrane, 2022b). For example, access control rules can determine if users can retrieve data or not.…”

Decentralization initiatives such as Solid, Digi.me, and ActivityPub aim to give data owners more control over their data and to level the playing field by enabling small companies and individuals to gain access to data, thus stimulating innovation. However, these initiatives typically use access control mechanisms that cannot verify compliance with usage conditions after access has been granted to others. In this paper, we extend the state of the art by proposing a resource governance conceptual framework, entitled ReGov, that facilitates usage control in decentralized web environments. We subsequently demonstrate how our framework can be instantiated by combining blockchain and trusted execution environments. Through blockchain technologies, we record policies expressing the usage conditions associated with resources and monitor their compliance. Our instantiation employs trusted execution environments to enforce said policies, inside data consumers’ devices. We evaluate the framework instantiation through a detailed analysis of requirments derived from a data market motivating scenario, as well as an assessment of the security, privacy, and affordability aspects of our proposal.

“…To answer this main research question, we analyze the requirements for a dApp control framework and conclude that control architecture and governance architecture are responsible for meeting decentralized requirements. In addition, coordination of decentralized control actions, including significant aspects of the consensus between peers and how to incentive collaboration between different peers, need to be investigated [14,15].…”

Effectively managing decentralized applications in cloud environments using a decentralized control paradigm is essential, as current cloud providers usually only offer a control interface for monitoring cloud infrastructures. This study proposes a decentralized service control framework for implementing the control across various organizations and coordinating collaboration among operators in a decentralized application. The proposed framework allows a consortium of organizations to control a shared distributed cloud infrastructure decentralized reliably. A consensus mechanism within the framework enables mutual coordination between the operators. This mechanism also uses an incentive protocol to enforce pro-active behavior and collaboration. We implement the framework with Hyperledger Fabric, and our experiments demonstrate its usability, reliability, and acceptable performance.
