Businesses and people together use cloud storage to transfer their vast amounts of data to unknown servers at a significantly lower cost than traditional methods. Several methods have been made to investigate the many aspects of this application scenario, such as efficiency, dependability, and security. Service providers can search and retrieve encrypted data in a cloud storage scenario where customers share their outsourced information with other users and convert their data before outputting it to a cloud storage service. The advanced technologies in cloud computing help them store and retrieve data securely anywhere at any time. Subsequently, in the cloud environment, security problem becomes a massive issue that defends further development in cloud computing and promotes remote data auditing. Several data auditing methods have been discussed in the research fiction, but those schemas still need to be improved for protected data sharing in cloud environments. This paper proposes a data-sharing schema for remote data auditing in a cloud environment. Our proposed method implements the CP-ABE (Attribute-based encryption) schema with minor changes in the access control policy structure to make it suitable for remote data auditing in the cloud environment. The experimental result shows that our protected data-sharing method can reduce data overhead when the user remotely shares the data in the cloud environment.
