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...
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.
As service-oriented architecture (SOA) continues to grow as a viable approach to systems development, so too does the number of services available. The strength of services in an SOA environment to provide interoperability comes at the cost of reduced privacy, as more interactions between autonomous services require more information to be exchanged. In this paper we define a metamodel for privacy...
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...
