Secure Deduplication for Cloud Storage Using Interactive Message-Locked Encryption with Convergent Encryption, To Reduce Storage Space

Abstract

The digital data stored in the cloud requires much space due to copy of the same data. It can b e reduced by dedupilcation, eliminating the copy of the repeated data in the cloud provided services. Identifying common checkoff data both files storing them only once. Deduplication can yield cost savings by increasing the utility of a given amount of storage. Unfortunately, deduplication has many security problems so more than one encryption is required to authenticate data. We have developed a solution that provides both data security and space efficiency in server storage and distributed content checksum storage systems. Here we adopt a method called interactive Message-Locked Encryption with Convergent Encryption (iMLEwCE). In this iMLEwCE the data is encrypted firstly then the cipher text is again encrypted. Block-level deduplication is used to reduce the storage space. Encryption keys are generated in a consistent configuration of data dependency from the chunk data. The identical chunks will always encrypt to the same cipher text. The keys configuration cannot be deduced by the hacker from the encrypted chunk data. So the information is protected from cloud server. This paper focuses on reducing the storage space and providing security in online cloud deduplication.

Orphanage Management Using IPFS and Hyperledger Fabric

“…Reports and prescriptions of patients can be stored using hash values of the patient ID, and only authorized persons can make transactions to retrieve stored reports. [3] The proposed blockchain-based architecture for e-healthcare systems offers several benefits, including improved security and privacy, greater transparency and accountability, and interoperability between different healthcare providers. By keeping the patient at the center of the system, the proposed architecture aims to provide a more patient-centric approach to healthcare data management.…”

“…Land Record Management using IPFS and Hyperledger Fabric [3] Land ownership records in many countries are fragmented and not available in a comprehensive single location, which creates inefficiencies and challenges for property buyers. The proposed solution presented in this paper involves bringing all stakeholders for a piece of land/property onto a single peer-topeer, decentralized network using Hyperledger Fabric, a blockchain framework.…”

Securing Cloud Data Against Cyber-Attacks Using Hybrid Aes With MHT Algorithm

“…Cloud computing handles larger data resources in world, all these resources are monitored in secure way [4]. The data storage is major problem in online cloud storage; the hybrid iMLEwCE algorithm provides better solution for this kind of problem [5]. The process of creating the virtual structure for big data system is known to be big data virtualization.…”
