with the rapid improvement of computation facilities, healthcare still suffers limited storage space and lacks full utilization of computer infrastructure. That not only adds to the cost burden but also limits the possibility for expansion and integration with other healthcare services. Cloud computing which is based on virtualization, elastic allocation of resources, and pay as you go for used...

Secure multi-party protocols have been proposed for entities (organizations or individuals) that don’t fully trust each other to share sensitive information. Many types of entities need to collect, analyze, and disseminate data rapidly and accurately, without exposing sensitive information to unauthorized or untrusted parties. Solutions based on secure multi-party computation guarantee privacy ...

The emerging hybrid cloud architectures allow organizations (users) to augment the private infrastructure with practically unlimited public cloud resources in order to cost effectively meet their intermittent peak demands. In such scenarios, users first utilize their already paid private computation infrastructure and offload selected tasks to the public cloud when the private resources become ...

Recently, cloud storage and processing have been widely adopted. Mobile users in one family or one team may automatically backup their photos to the same shared cloud storage space. The powerful face detector trained and provided by a 3rd party may be used to retrieve the photo collection which contains a specific group of persons from the cloud storage server. However, the privacy of the mobil...

Network virtualization opens a promising way to support diverse applications over a shared substrate by running multiple virtual networks. Current virtual data centers in cloud computing have flexible mechanisms to partition compute resources but provide little control over how tenants share the network. This paper proposes a utility-maximization model for bandwidth sharing between virtual netw...

With increasing growth of cloud services and the ability to choose from different cloud providers, we propose a new way to connect cooking workflows with a high security cloud storage. We use Activiti for workflow design and JavaScript Object Notation (JSON) for structured data interchange with a sealed cloud storage. This approach supports cooking workflows with instructions from multimedia da...

Cloud computing is becoming more and more adopted as infrastructure for providing service oriented solutions. Such a solution is especially critical when software and hardware resources are remotely distributed. In this paper we illustrate our experience in designing the architecture of a community cloud infrastructure in an industrial project related to integrated logistics (LOGIN) for made in...

In its generally essential structure, cloud balancing furnishes an organization with the capacity to convey requisition requests over any number of application deployments spotted in data centers and through cloud-computing suppliers. Cloud balancing takes a broader perspective of provision conveyance and applies specified limits and administration level agreements to each request. The utilizat...

As businesses are increasingly relying on the cloud to host their services, cloud providers are striving to offer guaranteed and highlyavailable resources. To achieve this goal, recent proposals have advocated to offer both computing and networking resources in the form of Virtual Data Centers (VDCs). Subsequently, several attempts have been made to improve the availability of VDCs through reli...

Companies that process business critical and secret data are reluctant to use utility and cloud computing for the risk that their data gets stolen by rogue system administrators at the hosting company. We describe a system organization that prevents host administrators from directly accessing or installing eaves-dropping software on the machine that holds the client’s valuable data. Clients are...
