Abstract
Data storage nodes that participate in a requested data statistical analysis as participant data storage nodes are determined and divided into a plurality of node sets. Data stored in each participant data storage node associated with a particular node set is encrypted, where the encrypted data is divided into a number of fragments at least equal to a number of participant data storage nodes associated with the particular node set. Each participant data storage node sends a portion of the encrypted data to each of the other participant data storage nodes within the particular node set. Each participant data storage node processes received encrypted data and data remaining on the particular participant data storage node to obtain a processing result. Each participant data storage node sends the processing result to a proxy node, wherein the proxy node performs data statistical analysis based on the processing result.
