Framework to Improve Data Integrity in Multi Cloud Environment

Abstract

Cloud computing is a network based environment where resources, information and software's are shared and provided to the users according to their demands. Though cloud computing is being widely used in various fields, it has certain drawbacks. Security issue is a concern in cloud computing. The confidentiality and data integrity should be guaranteed to the user who is putting their data over the cloud. This paper proposes a framework that would provide integrity of data of multiple users through Third Party Auditor (TPA) and proposes various algorithms to implement this framework. In the proposed framework concept of multi cloud has been used to provide best cost optimization for various requirements of user. The framework is also divided into three platforms namely: platinum for sensitive data storage, gold for less level of security and silver for least level of security on the data. Finally we have implemented different algorithms for the various platforms in the proposed framework. In the obtained results, we can find that the proposed framework is easy to implement and provides better performance by using the traditional algorithms of network security over the various issues of cloud computing.

Investigation on storage level data integrity strategies in cloud computing: classification, security obstructions, challenges and vulnerability

“…The deployment setup of data integrity strategy is dependent on the environment of the proposed system. Clients can store their data in public cloud set up [98], multi-cloud setup [99,100] or hybrid cloud set up [101]. If data are placed in a public cloud setup, clients lose access control visibility on data due to the outsider data management policy of CSP.…”

Efficient Information Maintenance Using Computational Intelligence in the Multi-Cloud Architecture

“…The cloud architecture is gaining very high importance recently and is becoming predominant on among various applications [3]. The benefits in the cloud [4] and more users to adopt the cloud service which in result causes a huge amount of data flow in the cloud causing difficulties in managing the and maintaining the storage of the information's The cloud paradigm [4] provides the multitudes of services such as the software, infrastructure, communication, network and the monitoring as service either under the public cloud paradigm that is shared among multiple of users or private cloud that is specifically used by one organization or group of similar organizations or the hybrid cloud that includes private cloud paradigm into the public cloud.…”

Implementing DNA Encryption Technique in Web Services to Embed Confidentiality in Cloud

“…Integrity in the document can be realized through XML signature and can also be realized as an identification of authentication and focused on the requirement of the confidentiality. In [7], Thakur and Gupta have implemented the idea of dividing the data into multiple clouds according to the level of integrity and confidentiality required to them and then applied the encryption techniques like Advanced Encryption Standards (AES), Data Encryption Standards (DES), and Digital Signature Standards (DSA). Authors have also compared four of these algorithms.…”
