Context-aware Dynamic Access Control for Pervasive Applications∗
As computing technology becomes more pervasive and mobile services are deployed, applications will need flexible access control mechanisms. Unlike traditional approaches for access control, access decisions for these applications will depend on the combination of the required credentials of users and the context and state of the system. In this paper, we extend the role-based access control mod...
متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
متن کاملDynamic Context Management for Mobile Applications
With the upcoming widespread availability of sensors, more and more applications depend on physical phenomena. Up-to-date real world information is embedded into business processes, in production environments, or in mobile applications, so that such context-aware applications can adapt their behavior to the current situation of their user or environment. For this, a high variety of so-called co...
متن کاملContext Information Management for Pervasive Computing
Pervasive Computing systems have to deal with the contextual information (context), which characterizes the current situation of the involved entities (e.g., users, mobile devices, environment, etc.). This dissertation studies context management issues related to the capability of a pervasive system on adapting its behavior to the involved entities context. Specifically, the interaction between...
متن کاملContext Fusion in Location-Aware Pervasive Applications
Location-awareness is an important aspect of context-aware applications. These applications enhance the functionality of ubiquitous computing services and applications by using numerous location sensing systems with variant precision and confidence levels. There is a need of seamless integration for these systems using a middleware infrastructure. In addition to interoperability of different sy...
