Abstract

The invention discloses a cloud data operation behavior-oriented trusted traceability method, which comprises the following steps of: setting hook points on a resource object of a user and a key path of an execution command, collecting operation event information of cloud data, and obtaining a traceability log of the cloud data; extracting a log abstract and related metadata of a traceability log, storing the log abstract and the related metadata on a block chain account book, and proposing an on-chain data storage mechanism based on a Merkel mountain range to support fine-grained verification and batch verification of the integrity of the traceability log; constructing a cloud data-oriented traceability model, providing a traceability mechanism combining a super blockchain account book and an ELK Stack technology, ensuring the credibility of a traceability log based on a Merkle mountain algorithm and a traceability log set while realizing an identity verification service, and providing a DAG-based behavior responsibility tracing method based on the credibility of the traceability log.

Description

technical field [0001] The invention relates to the field of big data data traceability, in particular to a trusted traceability method for cloud data operation behavior. Background technique [0002] In the era of big data, the rapid development of cloud computing has solved the problem of limited local resources of users. More and more users and enterprises choose to store data assets on cloud servers to fully enjoy the instant resource on-demand provided by cloud service providers. Assignment services. While massive amounts of data are uploaded locally to public cloud servers by users and enterprises, data security issues have become the focus of attention, especially in untrusted network environments where data leakage, tampering and loss occur from time to time , leading to the fact that the authenticity and reliability of the data cannot be guaranteed, and data traceability is one of the effective solutions to solve these problems. Data traceability refers to the man...
