Trust Management Model for Cloud Computing Environment

Software as a service or (SaaS) is a new software development and deployment paradigm over the cloud and offers Information Technology services dynamically as "on-demand" basis over the internet. Trust is one of the fundamental security concepts on storing and delivering such services. In general, trust factors are integrated into such existent security frameworks in order to add a security level to entities collaborations through the trust relationship. However, deploying trust factor in the secured cloud environment are more complex engineering task due to the existence of heterogeneous types of service providers and consumers. In this paper, a formal trust management model has been introduced to manage the trust and its properties for SaaS in cloud computing environment. The model is capable to represent the direct trust, recommended trust, reputation etc. formally. For the analysis of the trust properties in the cloud environment, the proposed approach estimates the trust value and uncertainty of each peer by computing decay function, number of positive interactions, reputation factor and satisfaction level for the collected information.Comment: 5 Pages, 2 Figures, Conferenc

Security oriented e-infrastructures supporting neurological research and clinical trials

The neurological and wider clinical domains stand to gain greatly from the vision of the grid in providing seamless yet secure access to distributed, heterogeneous computational resources and data sets. Whilst a wealth of clinical data exists within local, regional and national healthcare boundaries, access to and usage of these data sets demands that fine grained security is supported and subsequently enforced. This paper explores the security challenges of the e-health domain, focusing in particular on authorization. The context of these explorations is the MRC funded VOTES (Virtual Organisations for Trials and Epidemiological Studies) and the JISC funded GLASS (Glasgow early adoption of Shibboleth project) which are developing Grid infrastructures for clinical trials with case studies in the brain trauma domain

A survey of Remote Jobs and Communities Program(me) providers: one year in

This working paper reports on a survey of provider organisations conducted almost one year into the implementation of Remote Jobs and Communities Program. Abstract On 1 July 2013, a new labour market and community participation program-the Remote Jobs and Communities Program (RJCP)-started operating across remote Australia. It replaced several other programs, most importantly Job Services Australia (JSA) and the Community Development Employment Projects (CDEP) scheme. JSA has in recent years been Australia\u27s principal \u27mainstream\u27 labour market program in which all unemployment payment recipients in Australia who are able to work are expected to participate. CDEP is a much longer-standing program, originally designed to provide some form of paid work to Indigenous people living in remote communities. RJCP was presented by the Gillard Labor government as offering services that would be locally flexible, be delivered in partnership with communities and have a strong focus on getting people into work.  Its dual focus-on community participation and on jobs-was reflected in arrangements for its administration, jointly managed by the Department  of Families, Housing, Community Services and Indigenous Affairs and the Department of Education, Employment and Workplace Relations. However, a change of government in September 2013 brought RJCP into the Department of the Prime Minister and Cabinet. The new Abbott Coalition government was critical of RJCP and immediately included it in a review of Indigenous employment and training programs, led by Andrew Forrest. This working paper reports on a survey of provider organisations conducted almost one year into the implementation of RJCP. It is part of a larger research project on the implementation of RJCP during its first three years, with funding support from the Australian Research Council and Jobs Australia (Linkage Project 130100226). The project aims to understand how RJCP is developed from a general policy idea to specific grounded practice, at the community, regional and jurisdictional levels. This survey report includes findings about basic arrangements and characteristics of provider organisations; ideas about joblessness in remote areas and welfare conditionality; provider perceptions of the government officials with whom they work; operational details (staffing, money and administrative challenges including information technology (IT) systems); and broader influences on the shaping of program delivery, like Community Action Plans and community perceptions. A second survey in 2015–16 will track developments in these areas over time

The Funder and the Intermediary, in Support of the Artist: A Look at Rationales, Roles, and Relationships

This article, examining the ecology of funders' use of intermediaries and regranting organizations, came about as a direct offshoot of GIA's Research Initiative on Support for Individual Artists, begun in 2011. As the research team worked to map the pathways that support followed from funder to artist, a complex map of options and routes began to emerge, and intermediaries and regranters were often part of that picture. It became increasingly clear that this was an essential and important part of the overall system. It also emerged that this was an area of philanthropic practice that had been little examined, and about which little had been published. Interviews with funders during the research work also revealed that while a number of foundations were using intermediaries, their practices had independently evolved, and a wide range of methods and procedures were in use. What follows is the first tangible product of GIA's Research Initiative on Support for Individual Artists. In her analysis, Claudia Bach provides both an overview of the range of philanthropic practices involving intermediaries and regranters, as well as an exploration of a number of related topics and questions that emerged during the course of this work

D3.2 Cost Concept Model and Gateway Specification

This document introduces a Framework supporting the implementation of a cost concept model against which current and future cost models for curating digital assets can be benchmarked. The value built into this cost concept model leverages the comprehensive engagement by the 4C project with various user communities and builds upon our understanding of the requirements, drivers, obstacles and objectives that various stakeholder groups have relating to digital curation. Ultimately, this concept model should provide a critical input to the development and refinement of cost models as well as helping to ensure that the curation and preservation solutions and services that will inevitably arise from the commercial sector as ‘supply’ respond to a much better understood ‘demand’ for cost-effective and relevant tools. To meet acknowledged gaps in current provision, a nested model of curation which addresses both costs and benefits is provided. The goal of this task was not to create a single, functionally implementable cost modelling application; but rather to design a model based on common concepts and to develop a generic gateway specification that can be used by future model developers, service and solution providers, and by researchers in follow-up research and development projects.<p></p> The Framework includes:<p></p> • A Cost Concept Model—which defines the core concepts that should be included in curation costs models;<p></p> • An Implementation Guide—for the cost concept model that provides guidance and proposes questions that should be considered when developing new cost models and refining existing cost models;<p></p> • A Gateway Specification Template—which provides standard metadata for each of the core cost concepts and is intended for use by future model developers, model users, and service and solution providers to promote interoperability;<p></p> • A Nested Model for Digital Curation—that visualises the core concepts, demonstrates how they interact and places them into context visually by linking them to A Cost and Benefit Model for Curation.<p></p> This Framework provides guidance for data collection and associated calculations in an operational context but will also provide a critical foundation for more strategic thinking around curation such as the Economic Sustainability Reference Model (ESRM).<p></p> Where appropriate, definitions of terms are provided, recommendations are made, and examples from existing models are used to illustrate the principles of the framework

Supporting security-oriented, inter-disciplinary research: crossing the social, clinical and geospatial domains

How many people have had a chronic disease for longer than 5-years in Scotland? How has this impacted upon their choices of employment? Are there any geographical clusters in Scotland where a high-incidence of patients with such long-term illness can be found? How does the life expectancy of such individuals compare with the national averages? Such questions are important to understand the health of nations and the best ways in which health care should be delivered and measured for their impact and success. In tackling such research questions, e-Infrastructures need to provide tailored, secure access to an extensible range of distributed resources including primary and secondary e-Health clinical data; social science data, and geospatial data sets amongst numerous others. In this paper we describe the security models underlying these e-Infrastructures and demonstrate their implementation in supporting secure, federated access to a variety of distributed and heterogeneous data sets exploiting the results of a variety of projects at the National e-Science Centre (NeSC) at the University of Glasgow
