example 2

[0068] Example 2, when a user requests to delete certain entries in the database, the behavior data corresponding to the user's deletion operation, such as the user name of the user, the location of the deleted entry, and the number of deletions, can be recorded. The behavior data corresponding to each user deletion operation can be used as the audit information, or when abnormal deletion is detected, the behavior data corresponding to the abnormal deletion operation can be used as the audit information. For example, if it is detected that a user name deletes a large number of entries at one time, such as more than 1,000 items, the user name, the location of deletion, and the number of deletions can be recorded.

[0069] After the audit server generates audit information such as an audit log (audit log), an audit report can be generated according to the audit log.

Abstract

The embodiment of the invention provides a database auditing method and a database auditing device based on a block chain. The method comprises the steps of acquiring database auditing information; storing the database auditing information in a specified file system; calculating abstract information of the database auditing information; and storing the abstract information and the file informationof the database auditing information into a block chain cluster according to a block chain storage rule, wherein the file information is relevant information of the database auditing information in the specified file system. The database auditing information is stored in the specified file system, the abstract information of the database auditing information is stored in the block chain cluster,the data volume stored in the block chain cluster is small, the abstract information and the file information of the auditing information can be prevented from tampering by use of a consensus mechanism of the block chain cluster to achieve the purpose of preventing the auditing information and the abstract information thereof from tampering, thereby being beneficial to performing safety managementon a database.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based database audit method and device. Background technique [0002] Traditional database audit information, such as user login, database access and operation information, is usually recorded in a file or stored in another database. [0003] The database audit information is stored in the form of files or database records, and the risk of being tampered with is high, which is not conducive to the security management of the database. Contents of the invention [0004] Embodiments of the present invention provide a blockchain-based database audit method and device to solve one or more technical problems in the prior art. [0005] In the first aspect, the embodiment of the present invention provides a blockchain-based database audit method, including: [0006] Acquiring database audit information, the database audit information is information generated b...
