In this paper, we propose a novel scheme that can achieve data privacy by hybrid cloud, which consists of public and private cloud, and reduce storage and computation in private cloud, as well as communication overhead between private and public cloud. Meanwhile, we propose a novel algorithm to process private image data. Our experimental results show that (1) our algorithm achieves data privac...

In this research, we have built a framework of disaster recovery such as against earthquake, tsunami disaster and a heavy floods for e-Learning environment. Especially, our proposed framework is based on private cloud collaboration. We build a prototype system based on IaaS architecture, and this prototype system is constructed by several private cloud fabrics. These private cloud fabrics are o...

As the most basic cloud service model, Infrastructure as a Service (IaaS) has been widely used for serving the evergrowing computing demand due to the prevalence of the cloud. Using pools of hypervisors within the cloud, IaaS can support a large number of Virtual Machines (VMs) and scale services in a highly dynamic manner. However, it is well-known that the VMs in IaaS are vulnerable to co-res...

This poster session describes the selection criteria and process used for evaluating three repository software offerings and cloud platforms, with pros and cons. It describes implementation of workflows, representations of PREMIS metadata for objects in the repository, documenting fixity checks performed on datastreams, mapping of “rights” elements in DC datastreams to PREMIS “rightsExtension” ...

Cloud computing changed recently business view regarding their Information System through an on-demand provisioning of computing resources. Recent discussions about data security requirements in cloud computing environment tend to conflict with other requirement including usability and economic. In hybrid clouds that combine private and public clouds usage, private clouds are able both to exter...

Cloud Computing, the emerging technology, delivers IT capabilities as services-on-demand using internet. Though the Cloud technology possesses lot many benefits, it suffer several challenges which hinders the adoption of public cloud by many organizations. Since the consumer has to depend on the cloud provider’s infrastructure that is not completely controlled internally by the consumer, the ma...

Now a day's cloud computing became an attractive area of research and practices over the last few years. An increased number of private and public sector organizations have either adopted cloud company based solutions or seriously consider moving to cloud computing. In this paper we initiated a project designing and setting up a private cloud infrastructure in an academic environment. The ...

Private Virtual Infrastructure is a security architecture for cloud computing which uses a new trust model to share the responsibility of security in cloud computing between the service provider and client, decreasing the risk exposure to both. Private Virtual Infrastructure is under control of the information owner while the cloud fabric is under control of the service provider. The Private Vi...

Using data from 192 undergraduates asked to imagine a stressful experience, this study finds support for two primary contentions of a dual-process theory of supportive message outcomes: (a) message content impacts anticipated affect improvement (AAI) when processing motivation is high but not when low and (b) processing extent mediates the relationship between verbal person centeredness (VPC) a...
