in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...

According to Winkler [1], public cloud is based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model. The main benefits of using public cloud services

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...

Cloud computing represents today’s most exciting computing archetype. It gives computing via internet. Cloud systems can be used to enable data sharing capabilities and this can provide abundant of benefits to the user. It is the most important trend in cloud technology for allows users to access data expediently. Privacy and security is the big challenge for stored data in cloud. Most existing...

Worldwide governments are actively looking into cloud computing as a means of increasing efficiency of service delivery and reducing infrastructure costs. As a result of introducing cloud computing, interoperability issues arise and yet it is vital for e-government services to be efficiently achieved; this is also a challenge for the South African government. Systems providing e-services in dif...

This paper presents the various secure data sharing techniques in public clouds. A public cloud allows resources such as applications and storage to be accessible to the public over the internet. Due to the benefits of cloud storage, there has been a growing trend to use the public cloud for secure data sharing and storage. The public cloud storage model should solve the critical issue of data ...

Adoption of cloud infrastructure promises enterprises numerous benefits, such as faster time-to-market and improved scalability enabled by on-demand provisioning of pooled and shared computing resources. In particular, hybrid clouds, by combining the private in-house capacity with the on-demand capacity of public clouds, promise to achieve both increased utilization rate of the in-house infrast...

The objective of this paper is to perform a comprehensive performance comparison of public cloud services for computing and to analyze the correlation between their prices and performance. Eight representative public cloud providers were divided into two groups using market share: small cloud providers and large cloud providers. Results revealed that these offered computing services vary widely...

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...
