In the recent years great interest has been shown by both private organizations and independent researchers on Business Processes definition and management, which resulted in the development of several tools for their design and execution, and in proposals of standards for their formal representation, such as BPMN. At the same time, Cloud Computing solutions have reached a good level of maturity,...
Computer networks are becoming more and more important because of variety of services being applied through them, so is the trend of increase of threats to these networks. Traditional approaches of network security like packet filtering, IDS and more advanced IPS suffer from various problems. E.g. These mechanisms are not aware of the resources they are protecting, these mechanisms are independent...
The implementation of cloud computing in tele-health has enabled enormous benefits of improving health-care services as well as active health approaches, such as Patient-Centered Telehealth (PCT). Applying cloud systems enables healthcare users to obtain medical information from multiple cloud-based platforms or sources. Various service deployments meet different customers' needs. As one of the popular...
This paper introduces a novel sensor information fusion system enabling security and surveillance in large scale sensor saturated urban environments. The system is built over state-of-the art sensor networks middleware and provides information fusion at multiple layers. A distinguishing characteristic of the system is that it support seamless integration with semantic web middleware (including ontologies...
Managing a heterogeneous “outer edge” network is complex and error prone. It is typically performed by non-technical users. Effective HAN configuration may be hampered by a poor understanding of HAN service requirements. A challenge is to deploy and maintain meaningful and error-free heterogeneous HAN configurations. This paper explores an integrated solution to address the following requirements:...
The financial services industry presents some unique challenges in data integration, both within firms and across the securities trading process. This paper describes how the industry came to an awareness of the need to define semantics as an industry wide standard, and the methods and processes used to realize that requirement in the form of an industry Semantics Repository. The repository is described...
Automated composition and interaction of semantic web service is one of the most promising challenges in semantic web service research area, in which security research on service composition has attracted more attention. In this paper, we present a framework of Action labeled Kripke Transition System, which can abstract interaction behaviors between distributed web service and translate them into...
In the upcoming ambient intelligence applications, services provided by heterogeneous and often mobile platforms are combined to build intelligent environments. As these mobile services are hosted within different administrative domains, equally respecting security policies of all services becomes a challenge and conflicts between the policies of different domains can occur. The paper proposes an...
