A data integrity verification method and system based on a root random number to ensure secure distributed data storage on a public cloud. A new root random number can be generated in response to receiving a file for storage to the public cloud. A unique random number tag for each data chunk associated with the file can be calculated via a shift operation and the tag can be added to the data chunk.
