A Brief Survey of Cloud Data Auditing Mechanism

Abstract

AbstractIn today’s digital world, the demand for cloud storage is increasing. Cloud has attracted a vast number of users in today’s environment because it delivers a wide variety of services. Users can access data from the cloud server whenever they need it, and data owners can store any type of data on it. It provides a cost-effective solution for medium and small businesses, releasing them from the burdens of data storage. The term “cloud storage” refers to data storage on a centralized server that is part of another organization’s infrastructure. The corporation owns and operates the data storage, while the user is charged with the storage space used. Since the data is processed on a cloud server, the accuracy of data storage is jeopardized. Users have a low level of trust in cloud service providers because they can be deceiving at times. These programs often come with a critical concern, and due to newly introduced policies such as GDPR, the organizations can face legal and financial consequences. Since the cloud infrastructure is regulated by a cloud service provider, a separate operating agency, data privacy is critical. As a result, several auditing schemes have been proposed to protect the integrity and confidentiality of cloud records effectively. In this article, we looked at a variety of existing data integrity auditing systems and their outcomes.KeywordsData integrityCloud storageThird-party auditors (TPA)Cloud service provider (CSP)Merkle Tree
