Dynamic Data Storage And Verifications In Cloud Environments

Abstract

This project explores a decentralized data management system involving data owners, data processors, fog servers, cloud service providers, and third-party verifiers. The primary goal is to ensure secure data access, authorization, and verification in a distributed environment. The data owner shares sensitive data with a data processor, who uses fog servers for processing. To achieve decentralization, two fog servers are implemented to distribute the workload and enhance system reliability. These fog servers are responsible for managing the data between the data owner and the data processor. The project we have implanting a data share we have used a Homomorphic Encryption The cloud service provider plays a crucial role by maintaining the infrastructure and providing the necessary resources for the servers. Additionally, a third-party verifier is introduced to oversee the integrity and validity of the data access requests. The third-party verifier requests permission from the data owner to view a particular file. If the data owner grants permission, the file is made accessible to the verifier; otherwise, access is denied. This project aims to provide a robust, decentralized architecture that secures data access, ensures privacy, and allows for transparent verification of access requests. By leveraging fog computing, decentralization, and third-party verification, the system ensures that data owners retain control over their files while facilitating secure and authorized data interactions.
