Auditing method and device for data file access based on a block chain

Abstract

The invention provides an auditing method and device for data file access based on a block chain. The method comprises the following steps: receiving a request for data file access; Judging whether auditing is needed or not according to the access type of the data file access request; When it is judged that auditing needs to be carried out, corresponding auditing data is generated corresponding tothe data file access request, and the auditing data is written into a local storage space and a block chain; Processing the data file access request, and returning a result corresponding to the datafile access request to the application; The auditing device comprises an interface communication unit, a data auditing unit and a data operation unit. According to the invention, the reliability and credibility of audit data can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a block chain-based auditing method and equipment for data file access. Background technique [0002] With the development of IT technology, using the network for information exchange and processing has become a relatively common communication method, which undoubtedly improves the efficiency of information transmission and exchange, but also increases the risk of private data information leakage. [0003] In the prior art, auditing access to private data files is a more effective way to protect sensitive data. Specifically, the auditing equipment for auditing is usually based on a single point or a local area network, and an audit module is embedded on the file system or inside the file system. The audit module monitors the access process of data files in real time, generates access records, and then records the results Local storage space stored on the local machine or...

Problems solved by technology

[0004] However, in the actual application process, the above-mentioned audit equipment has two risks. One is the reliability risk of the audit information, such as failure of the location where the audit information is stored or damage to the storage medium, resulting in the loss and irrecoverability of the audit information; On the other hand, the credibility risk of audit information, because the audit information is stored in a stand-alone or local storage space, the data itself does not have a complete anti-tampering capability, then there is a theoretical modification of the audit information, including malicious addition Or delete access records, etc., which will affect the credibility of audit information
