An Efficient Data Storage Technique for User Files in Cloud

A remote data storage service provided by cloud providers is known as cloud storage. It substitutes an online-accessible central storage repository for the need for nearby physical storage devices. Cloud storage is efficient due to its wide range of accessibility. An efficient approach for managing file storage in cloud computing environments is presented in this paper. The proposed method utilizes the concept of dividing files into blocks and combining them to generate file hashes using Merkle hash tree (MHT). These file hashes facilitate quick and reliable data integrity verification. Upon transmission of multiple files to the Cloud Service Provider (CSP), a secure storage process is implemented within the cloud environment. The data packets are organized and managed through a $B+$ tree structure. The proposed scheme also supports dynamic file operations. Where users can modify files, and for each modification, a new file hash is generated by merging the block hashes through MHT. By combining the efficiency of Merkle hash tree and B+ tree structures, this proposed system offers a dependable solution for effectively managing files in cloud storage. This method makes a significant contribution to the fields of cloud computing and file management by improving data security, integrity, and accessibility.
