Track determination method, device and system based on blockchain, and electronic equipment

Abstract

The invention provides a track determination method, a device and a system based on a blockchain, and electronic equipment, which can be used in the block chain field, the financial field and the like, and the method comprises the following steps: receiving a track acquisition request from a client, the track acquisition request comprising a user identifier and a query condition, the query condition comprises at least one of a time range and a regional range; in response to the track acquisition request, respectively acquiring sub-track information sets matched with the user identifier and the query condition from at least two block chain networks, each piece of sub-track information in the sub-track information sets having a track information identifier including time information; combining and sorting the sub-track information in the one or more sub-track information sets based on the time information to obtain a track information set; and sending the associated information of the track information set to the client, so that the client displays the associated information of the track information set.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain and the financial field, and more specifically, to a method, device, system and electronic equipment for determining a trajectory based on blockchain. Background technique [0002] The blockchain system encrypts and hashes data and data operation records through cryptographic methods, thereby forming an open, transparent, non-tamperable, and traceable distributed database accounting system. This technology can be widely used in payment and settlement, deposit and collection of evidence, value transfer, supply chain finance, user credit investigation, regulatory audit and other fields. [0003] Taking the scene of finding a citizen’s recent activity track as an example, the relevant technology is mainly based on questionnaire survey, which integrates the location of telecom operators, security videos, public transport tickets and other information, and obtains the approximate personal i...

Problems solved by technology

[0004] In the process of realizing the concept of the present disclosure, the applicant found that there are at least the following problems in related technologies: banking systems, telecommunications operating systems, public security systems, and public transportation systems usually have their own blockchain networks, and each blockchain network only records Partial trajectory information, it is not easy to obtain more comprehensive trajectory information of citizens
