To comply with personal data protection regulations, systems that handle personal data must ensure that they verify users’ consent to use their information for a specific purpose. Validating consent is not a simple task, as the purpose typically begins ...

In the Internet of Things (IoT) epoch, the seamless communication of smart devices through autonomous collaboration demands real-time IoT networks to possess a high level of intelligence. However, the resource-constrained nature of IoT limits the ...

Authorization mechanisms are essential for securing microservice-based applications, with Attribute Based Access Control (ABAC) being a prominent choice for fine-grained authorization. A decentralized authorization mechanism allows the transfer of ...

With the rapid development of information technology, the traditional access control model has faced challenges in meeting the demands of practical applications. As a result, the ABAC model has emerged as a more flexible and adaptable solution, ...

The innovation process typically follows a predefined sequence of phases: idea generation, screening, evaluation/selection, development, and launch/diffusion. This process exhibits a dynamic and cyclic structure. At each stage, potential ideas may ...

In order to improve the degree of data sharing between enterprises and departments in the supply chain and strengthen the data access transparency and privacy protection ability, a hierarchical access control mechanism for supply chain data based on ...

Personal health records (PHRs) have significant value for health management, accurate diagnosis, and disease research. However, PHR sharing may raise owners’ concerns about security deficiency and privacy leakage. The current mainstream PHR ...

This position paper presents a method to ease the management of data security from the user point of view. Nowadays, users have many ways to access the same data: direct connection to the host, shared filesystem or web drive-like solutions. This ...

In today's increasingly complex and dynamic environments, traditional access control models often fail to adequately address the diverse requirements and security challenges. Various models have evolved to handle the security issues all dimensions of ...

The graph data model is increasingly used in practice due to its flexibility in modeling complex real-life data. However, some security features (e.g., access control) are not receiving sufficient attention from researchers since that graph ...

In recent years, supply chains have evolved into huge ecosystems, demanding trust, provenance, and data privacy. Since blockchain technology (BCT) allows for the development of a distributed environment, it is ideal for supply chain management (...

• A multi-blockchain data privacy-preserving framework with fine-grained access control.
• Two separate ledgers to store business operations and contracts to maximize scalability.
• The architecture guarantees an efficient, scalable and ...

Modern healthcare institutions are now equipped to provide telecare services because of substantial improvements in telecommunication. Numerous services are provided through the telecare system. For efficient utilization of telecare service, ...

Since Software-Defined Networking (SDN) allows apps to interact with network-critical resources at the control plane through northbound interface, people hope that these apps have the same level of trust as the controller. Most researchers use ...

Access control is one of the key mechanisms used for protecting system resources. While each of the existing access control models has its own benefits, it is difficult to satisfy all the requirements of a contemporary system with a single model. ...

One of the challenges in Attribute-Based Access Control (ABAC) implementation is acquiring sufficient metadata against entities and attributes. Intelligent mining and extracting ABAC policies and attributes make ABAC implementation more feasible ...

Internet of Things (IoT) has become an essential technology in different daily life domains including health, industry and finance among many others. The implementation of IoT systems requires different underlying technologies such as applications,...

Recent emergencies, such as the COVID-19 pandemic have shown how timely information sharing is essential to promptly and effectively react to emergencies. Internet of Things has magnified the possibility of acquiring information from ...

Attribute-Based Access Control (ABAC) is one of the most popular and fits access control methods for the Internet of Things (IoT). Yet, despite its popularity, just a few works address the attribute management and retrieval challenges ...

Supply chain finance (SCF) provides credit for small and medium-sized enterprises with low credit lines and small financing scales. The resulting financial credit data and related business transaction data are highly confidential and private. ...

The use of the Cloud computing has been constantly on the rise. However, there are many challenges associated with the Cloud, such as high bandwidth requirements, data security, vendor lock-in and others. The recent rise of decentralized file systems (...
