Digital Video Content is now pervasive and services like IPTV are gaining traction on hand held devices too. Android, a software platform from Google, pioneering middleware and applications for handheld devices does not offer support for content management services by design. Motivated by these observations, we propose an aggregate model software platform to offer content management and value added...
Grid-oriented middleware implements basic operations of the grid infrastructure such as coordination of the access to resources, authentication,discovery resources, and quality of service management. However, building a grid-oriented middleware is a complex task due to the complexity of the aforementioned operations, the inherent heterogeneity of grid computing environments and the large number of...
For aspect oriented Web service orchestration, there are two major problems, aspect determination and crosscutting base with aspect. Contrary to other researches focusing on implementation, this paper presents an aspect oriented design method, Themes4BPEL. The novelty of this approach is that it includes five rules to differentiate aspect from base with three views analysis. And the test cases for...
Personalized information services are services which deliver the right information at the right time on a way preferred by the users, and help users to cope with the increasing amount of information available on the Internet. The arrival of the ambient intelligent (Ami) era brings great opportunities to personalized information services. In order to satisfy the users' personalized requirements better...
We developed a framework for reflective middleware that monitors security capabilities that every software component has. The main idea is to monitor the applications, changing or tuning the software components with the explicit goal of making the whole system as secure as possible. The middleware is flexible enough to be configured with the specific needs of the system that is going to be monitored...
The three-tier architecture pattern and its variants have been around for a while and there are several discussions of their properties as well as several patterns. None of these discussions considers security. However, several real systems implement this approach including security. We revisit this pattern to explicitly separate and analyze its security aspects.
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
Privacy helps to establish personal autonomy and create individualism. Privacy is a state or condition of limited access to a person. In particular, information privacy relates to an individual's right to determine how, when, and to what extent information about the self will be released to another person or to an organization. It can be said that privacy is a much broader concept than security; privacy...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
