Problems solved by technology

[0007] Since the transmission paths of different source data are different, all types of source data need to be screened when tracing the source of information, making the amount of data during screening larger. The reason is that when the source data is stored Classification is not performed according to the corresponding scenario, resulting in a large amount of data traversed during concurrent processing by the system

Abstract

The present invention provides a block chain-based information traceability method and system, comprising: receiving a traceability request, the traceability request includes a category tag, a time tag, and a content tag; Access to obtain target path data, the target path data is one of single-source path data or multi-source path data; determine the corresponding first-level data set based on the time tag, and the target path data includes multiple first-level data sets; The content tag determines a corresponding secondary data set, the primary data set includes at least one secondary data set; path information in the secondary data set is extracted, and at least one information source is obtained based on the path information. The technical solution provided by the present invention can quickly locate the information source according to different tags in the traceability request when tracing the source of the information, reduces the amount of data traversal when searching for the information source, saves the search time of the information source, and has high efficiency.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a blockchain-based information traceability method and system. Background technique [0002] Information traceability includes single-source information traceability and multi-source information traceability. [0003] Single-source information traceability refers to the problem of information traceability when the source node of information dissemination is a single source node. On a social network, the network itself is abstracted into a graph structure, and information is propagated from point to point along edges. In some cases, since only the state of some nodes is observed, or only the subgraph formed after the propagation result occurs, it is impossible to directly determine which node the information propagation starts from, so information traceability is required. [0004] Multi-source information traceability refers to the problem of information ...
