Abstract

The invention discloses a backup data processing method and a backup data processing device, used for verifying whether backup data is tampered, thus improving security of the backup data. The method comprises the steps of when target data is recovered according to the backup data of the target data, generating a digital digest corresponding to the backup data; constructing a first binary tree consisting of the digital digest; computing a first Hash value of the root node of the first binary tree; comparing the first Hash value with a preset identifier of the target data; and when the first Hash value is the same as the identifier of the target data, recovering the target data according to the backup data of the target data. By using the method provided by the invention, whether the backup data is tampered can be verified by comparing the Hash value of the root node of the binary tree corresponding to the backup data with the identifier of the target data, so that data recovery security is improved.

Description

technical field

[0001] The invention relates to the technical field of the Internet, in particular to a backup data processing method and device. Background technique

[0002] Data backup refers to the process of copying all or part of the data set from the application host to other storage media. When the data in the application host is destroyed by an accident, check the integrity and security of the backup data. When the integrity and security of the backup data pass the check, the backup data can be used to restore the data in the application host.

[0003] However, in the prior art, the inspection of data security only checks whether the data is infected by a virus or not. It is impossible to check whether the data has been tampered with by humans. And some institutions involve the security of data is extremely important, such as banks. When performing data recovery, the backup data that has been illegally tampered with is imported into the application host, and the ...
