In this paper, the security problems in private cloud storage are discussed and studied, and the main research work includes: 1. The research status of private cloud storage technology at home and abroad is summarized, and the security problems of private cloud storage are pointed out. 2. The data integrity verification technology in private cloud storage is studied, and a data integrity verification protocol for private cloud storage is proposed. The protocol has adaptability, for smaller files, can check all the data blocks to ensure the effectiveness of the results, but for larger files, you can check some of the data block to a certain probability to ensure the integrity of the data, so as to reduce system resources and network bandwidth consumption. 3. This paper studies the load balancing technology in private cloud storage, this paper proposes a method of data slicing and backup based on ID signature, finds storage nodes by using the corresponding relation between file block ID and available storage node ID, and allocates effective storage nodes randomly for corresponding file blocks in the presence of failure nodes, which improves the efficiency of the primary server. The data files that will need to be backed up are partitioned and selected for optimal backup area storage on multiple storage nodes by a specified number of data replicas. 4. Using the above technology, a private cloud storage system based on distributed cluster architecture is designed, which realizes the fragment uploading, downloading and backup of data, and encrypts the data during uploading and downloading, and can verify the data integrity. The innovations of the paper include: (1) The proposed data integrity verification protocol can be dynamically based on the size of the file integrity check, the system requires a small amount of storage overhead and communication overhead, it can guarantee the effective implementation of the Protocol, and as the file increases, the time spent is still kept at a lower value; (2) The improved load balancing technique is to find the storage nodes of all the blocks of the file by using the corresponding relationship between the file Block ID and the available storage node ID in the process of uploading files, which reduces the system time cost and improves the system efficiency compared with the general method. In this paper, a private cloud storage system based on distributed cluster architecture is designed to prove the feasibility and security of each method in theory, so as to ensure that these methods can be applied in practice.
