We consider a cloud data storage involving three entities, the cloud customer, the cloud business centre which provides services, and the cloud data storage centre. Data stored in the data storage centre comes from a variety of customers and some of these customers may compete with each other in the market place or may own data which comprises confidential information about their own clients. C...

With the vast development in cloud computing model, various organizations and individuals often deploy the cloud without reviewing the security policies and procedures which can cause great risk in their business. Securing data in cloud storage becomes a challenging task not only for the cloud user but also to the Cloud Service Provider (CSP). Storing secret data in unencrypted form is suscepti...

Cloud computing has not only gained enormous popularity, but also been deployed successfully in large scale realworld applications. However, the popularity of the cloud storage also leads to the dilemma between end-user(EU) and cloud storage provider(CSP), i.e, the EU focuses its attention on acquiring cheap cloud storage services, while CSP concerns how to maximize its own revenue by setting p...

Cloud computing is an internet based independence, scalability, elasticity, ubiquitous network access, resource pooling and pay Cloud storage is nowadays very popular storage system. Cloud storage is storing of data storage which is maintained by third party. Cloud storage is saving of digital data in logical pool and physical storage spans multiple servers which are manage by third party. Thir...

Cloud-based storage services have established themselves as a paradigm of choice for supporting bulk storage needs of modern networked services and applications. Although individual storage service providers can be trusted to do their best to reliably store the user data, exclusive reliance on any single provider or storage service leaves the users inherently at risk of being locked out of thei...

Cloud storage is in widespread use by individuals and enterprises but introduces a wide array of attack vectors. A basic step for users is to encrypt their data, but it is not obvious what precise security properties are required for encryption. Furthermore, cloud storage providers often use techniques such as data deduplication for improving efficiency which restricts the application of semant...

The cloud storage provides a least cost means of data storage for the small and large enterprises across the globe. But the main barricade to wide spread adoption of cloud storage is the lake of trust in the technology by its user. The data is stored on multiple servers and the location is concealed from the customers and they are no more in control of the data. This distinctive feature of the ...

This paper presents a duplication-less storage system over the engineering-oriented cloud computing platforms. Our deduplication storage system, which manages data and duplication over the cloud system, consists of two major components, a front-end deduplication application and a mass storage system as backend. Hadoop distributed file system (HDFS) is a common distribution file system on the cl...

Cloud computing is an upcoming efficient networking computing environment. Our work proposes sharing an application across various clients of a host system via cloud computing. The sharing is performed between the host storage system and the remote storage system in a cloud computing environment. The Host storage device of the host system is updated to retrieve the application from the remote s...

Community networks are decentralized communication networks built and operated by citizens, for citizens. The consolidation of todays cloud technologies offers now for community networks the possibility to collectively built community clouds, building upon user-provided networks and extending towards cloud services. Cloud storage and in particular secure and reliable cloud storage, could become...
