Lightweight Auditable Secure Cloud Storage With Privacy Enabled Data Storage Optimization

A Secure Storage Management & Auditing Scheme for Cloud Storage

“…We considered a data access control system in multi-authority cloud storage, as described in Fig. 3.1 There are 5 kinds of entities within the system: a security key generation and distribution module which is responsible for generating cryptographic keys and distributing them among data owners and users, data owners are responsible for outsourcing data over cloud, data users can only request for data and download data if respective owner of that data permits it, lastly the third party auditor an audit the data to check integrity of that data [19]. The module works by splitting the original file into chunks and generating a log file with the order in which those chunks should be re-assembled.…”

Role Based Secure Data Access Control for Cost Optimized Cloud Storage Using Data Fragmentation While Maintaining Data Confidentiality

“…Each of these access control models has its own advantages and disadvantages. The choice of access control model will depend on the specific security requirements of the cloud computing environment [4][5] [38] The proposed paper introduces a comprehensive framework for cost-optimized cloud storage that addresses the challenges of maintaining data security, privacy, integrity, and availability at lower cost. The proposed framework leverages a secure authenticity scheme to protect data during storage or transfer over the cloud, and a two-layer security approach that ensures only authorized users can access sensitive data.…”
