I.INTRODUCTION In this paper with the potentially unlimited storage space offered by cloud providers, users tend to use a large amount space as they can and vendors continually look for techniques aimed to reduce redundant data and exploit space savings. A technique which has been widely adopted is crossuser deduplication. The simple idea behind deduplication is to accumulate duplicate data onl...

Nowadays,more andmore Internet users use the cloud storage services to store their personal data, especially when the mobile devices which have limited storage capacity popularize. With the cloud storage services, the users can access their personal data at any time and anywhere without storing the data at local. However, the cloud storage service provider is not completely trusted. Therefore, ...

Offshore and outsourced distributed software development models and processes are facing challenges, previously unknown, with respect to computing capacity, bandwidth, storage, security, complexity, reliability, and business uncertainty. Clouds promise to address these challenges by adopting recent advances in virtualization, parallel and distributed systems, utility computing, and software ser...

Cloud is growing technology for enabling ondemand access to a shared pool of configurable server resources (applications, networks, memory, storage, processors and services) with infrastructure that can be rapidly provisioned and released with minimal management efforts. Cloud offers the promise of massive cost savings combined with increased IT agility due to different advantages like pay per ...

Besides well-known benefits, commodity cloud storage also raises concerns that include security, reliability, and consistency. We present Hybris key-value store, the first robust hybrid cloud storage system, aiming at addressing these concerns leveraging both private and public cloud resources. Hybris robustly replicates metadata on trusted private premises (private cloud), separately from data...

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 ...

Physical location of data in cloud storage is an increasingly urgent problem. In a short time, it has evolved from the concern of a few regulated businesses to an important consideration for many cloud storage users. One of the characteristics of cloud storage is fluid transfer of data both within and among the data centres of a cloud provider. However, this has weakened the guarantees with res...

Rendering efficient storage and security for all data is very important for cloud computing. Securing and privacy preserving of data is of high priority when it comes to cloud storage. Therefore to provide efficient storage for cloud data owners and render high security for data this paper proposes Cloud Computing Secure Framework (CCSF). Thus CCSF consists of four segments: 1) Identity Managem...

Safe file sharing mechanism in cloud storage is one of the most significant elements that affects the development of security technology. With application of homomorphic key agreement mechanism, Shamir secret sharing algorithm, Bloom Filter and B-tree search algorithm and Rsync data updating algorithm, a safe file sharing scheme in cloud storage is established based on cloud storage infrastruct...

Cloud storage could be a storage of information on-line in cloud that is accessible from multiple and connected resources. Cloud storage will offer smart accessibility and reliability, sturdy protection, disaster recovery, and lowest price. Cloud storage having vital practicality i.e. securely, with efficiency, flexibly sharing information with others. New public–key cryptography that is named ...
