The development of information systems in healthcare has grown considerably in recent years. With the evolution of systems based on distributed processing, using the Internet and cloud computing systems can develop much more effective and efficient, particularly in the health field. The proposed system involves the creation of databases, distributed or not, with integration of Web services that may...
The Web Service has been extended to the back-end database. In this paper, we propose a novel method of user behavior analysis in semantic network. We use the weight value to analyze and record user behavior and then check user behavior record with the signatures which are generated by the Intrusion Detection System (IDS). If a user record matches with signatures, the system will pass the record to...
The dynamic nature of the Internet poses various challenges to the successful execution of composite Web services. Failures are samples of these challenges. It needs to be addressed for the smooth progress of Web service composition. Unfortunately, the de facto standard for modeling composition namely BPEL is not equipped with mechanisms that let Web services "heal" themselves in case of...
Several vulnerability analysis techniques in web-based applications detect and report on different types of vulnerabilities. However, no single technique provides a generic technology-independent handling of Web-based vulnerabilities. In this paper we present our experience with and experimental exemplification of using the application vulnerability description language (AVDL) to realize a unified...
This paper proposed a two layer authorization mechanism, including traditional password system and rhythm recognition. The whole system includes two phases: preprocessing and usual operation for users. In preprocessing phase, users type password in a specific rhythm in order to record and analyse the characteristics of behaviour of users. In the second phase, how to verify a user in usual operation...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In recent years, organizations have been shifting focus to their core business competencies, and reducing total cost of ownership (TCO) associated with training and management of their IT infrastructure. In the same motif, organizations are establishing security and survivability frameworks as an integral part of their business strategy so as to provide an acceptable quality-of-service for their clients...
