With the expanding volume of smart grid data, cloud storage has emerged as a cost-effective scheme for their maintenance. However, storing plaintext data in the cloud may lead to a significant risk of privacy leakage of web data. Existing cryptography-based systems are often inefficient because data must be decrypted to access it. To address these challenges, a new approach for verifiable digital text discovery is proposed. The program allows recovery operations to be performed while ensuring data confidentiality and availability. This new scheme involves: Generating root hashes using Merkle trees and leverage Blockchain guarantees the trustworthiness of search results. In addition, a multi-cloud heterogeneous distributed system storage system is designed to store user data, which has the ability to repair damaged data. This feature not only improves data security, but also ensures data availability. Finally, the security analysis and simulation results verify the security and efficiency of the protocol.
