A New Data Deletion Scheme for a Blockchain-based De-duplication System in the Cloud

Abstract

Almost all Cloud Service Providers (CSP) takes a principled approach to the storage and deletion of Customer Data. Most of them have engineered their cloud platform to achieve a high degree of speed, availability, durability, and consistency. Their systems are designed to be optimized for these performance attributes and must be carefully balanced with the necessity to achieve accurate and timely data deletion.many researchers have turn their focus toward data storage and how it will be a challenging task for CSPs in term of storage capacity, data management and security, a considerable number of papers has been published containing new models and technique that will allow data De-duplication in a shared environment but few of them have discussed data deletion.In this paper we will be discussing a new approach that will allow a smart deletion of data stored in the file system as well as its reference in the Blockchain since, by its nature, Blockchains does not allow deletion without violating the Blockchain’s consistency, a preexisting de-duplication system will be our base platform on which we will be working to achieve an accurate and secure data deletion using Blockchain technology while preserving its consistency.

Data Modifications in Blockchain Architecture for Big-Data Processing

“…Bosona et al [24] and Li et al [25] also worked on the traceability and access management solutions on supply chain using the blockchain technology. El Khanboubi et al [26] employed a blockchain protocol to enable the smart deletion of duplicated data. In this method, deduplication is easily verified using blockchain features, and automatic deletions are enabled for duplicate data.…”

Deletion-Based Tangle Architecture for Edge Computing

“…Summary blocks are created only in specified intervals, and the expired data between the intervals must wait until the process is triggered. As an alternative approach, Khanboubi et al [20] introduced a data-deletion technique for blockchain-based data deduplication systems. Yang et al [23] moved data deletion rights to the public in cloud data management using blockchain.…”

“…Therefore, a large research gap exists in enabling blockchain for big data processing. To address this issue, researchers have already introduced several state-of-the-art projects enabling data deletions from blockchains [20][21][22]. Based on the observations of the proposed projects, categorizing blockchain data deletion techniques into blocks and selective deletions is possible.…”
