Privacy for Service-Oriented Architecture (SOA) is required to gain the trust of those who would use the technology. Through the use of an independent privacy service (PS), the privacy policies of a service consumer and provider can be compared to create an agreed upon privacy contract. In this paper we further define a metamodel for privacy policy creation and comparison. A trust element is developed...
As many software systems have been turned as Web services, the evolutionary changes of Web services are becoming an important issue. To understand the way in which the change affects the services, we must ascertain parts of the system that will be effected by the change and examine them for additional impacts. In this paper, we propose an impact analysis model based on service dependency. In particular,...
Service-Oriented Architecture (SOA) is a paradigm for creating and encapsulating business processes in the form of loose-coupling, autonomous and abstracted services. Managing the non-functional requirements of SOA such as security, is an over arching problem due to the wide variety of ways the service consumer can access the services offered by the service provider and the equally varied restrictions...
In this paper we propose the creation and use of a privacy policy vocabulary. The elements of this policy will have criteria for comparison, creating hierarchical relationships between those elements that could not otherwise be directly compared. This policy vocabulary can be used in conjunction with the eXtensible Access Control Markup Language (XACML) to provide storage and enforcement.
The WebInVivo project aims at providing automated support for clinical research on neglected diseases. It includes mechanisms for (a) sharing and reusing clinical trial assets, such as protocols, protocol data, workflows and workflow metadata and (b) controlling the protocol life cycle, from modelling to execution. In this project, collaboration in the biomedical area will permeate three segments...
One of the most significant difficulties with developing service-oriented architecture (SOA) concerns its security challenges. In particular, the authorization task is especially demanding because of the diverse access requirements within the various SOA environments, such as the business world, the academic setting and the industry atmosphere. In this paper, we propose a 4-attribute vector authorization...
Software testing is a very expensive and time consuming process. It can account for up to 50% of the total cost of the software development. Distributed systems make software testing a daunting task. The research described in this paper investigates a novel multi-agent framework for testing 3-tier distributed systems. This paper describes the framework architecture as well as the communication mechanism...
SIGMA is a conceptual multiagent system architecture for supervisory systems that aims to improve the integration and coordination of heterogeneous tools and techniques. This paper presents an overview of the analysis and design of SIGMA according to the Gaia methodology and agent UML (AUML) diagrams
