Abstract

The invention discloses a data checking method, and the method is executed in computing equipment and comprises the following steps: acquiring a plurality of block files corresponding to file data, wherein the plurality of block files comprise process data generated in a data checking process; checking whether the deleted block file exists in a deletion list or not to determine whether the deleted block file is recovered or not; respectively calculating hash values of the plurality of block files, and performing calculating to obtain a to-be-verified root hash value according to the hash values of the plurality of block files; and comparing the root hash value to be verified with a root hash value stored in the computing device to determine whether the file data is modified. The invention also discloses a corresponding computing device. According to the data checking method, the efficiency of checking the data integrity is improved, and the data security is ensured.

Description

Technical field

[0001] The present invention relates to the field of computer technology, and more particularly to a data inspection method and a computing device. Background technique

[0002] Currently, when encrypted with metadata, the file data is generally divided into fixed-size block files to prevent data information. For attackers, even if you get these block files, you cannot get information on the directory structure, file name, file size, and other information. However, these encrypted block files are in the transmission or stored procedure, the data content is still possible to be tampered with by an attacker. For example, the specific tamper means, for example, modify the rear data of the block file, replaced with the old version of the block file, and the recovery has been deleted. Block file, etc.

[0003] In accordance with the prior art solution, an ID check is added to the block file. Specifically, the program generates a file name as a block file, and stores th...
