Abstract

The invention discloses a data storage method. The data storage method is used for solving the problem that the truth of the data cannot be guaranteed in the prior art. The method comprises the following steps: confirming a Hash value of a target file; utilizing the Hash value of the target file to construct a Hash tree and extracting a root Hash value of the Hash tree; storing the root Hash value in a block chain, thereby acquiring storage information of the truth of the target file, wherein the storage information includes a sign of a block of the Hash value of the target file, a storage time stamp of the target file and the Hash value of the target file. The invention also discloses a data storage device, a data verification method and a data verification device.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data storage method and device, and a data verification method and device.
