A method of data integrity detection for fine-grained cloud storage

In the cloud storage service, a fine-grained cloud storage data integrity detection method is proposed to enable users to quickly and easily know the integrity of the data on the cloud server. The file is divided into a file block and then divided into a basic block, through the introduction of bilinear pairs and users randomly selected to detect the data block can detect the integrity of the data indefinitely, in addition, through the introduction of trusted third party to solve cloud user and cloud vendor disputes, to achieve the public verification of cloud storage data. Then the correctness and security analysis of the proposed method is given, and it is proved by experiments that this method can detect the integrity of cloud storage data well.
