ETC data right confirmation system based on block chain technology

Abstract

The embodiment of the invention discloses an ETC data right confirmation system based on a block chain technology. The system comprises a toll station system and a block chain platform, wherein the toll station system is used for encrypting transaction flow data by using an encryption key corresponding to a road section owner after the ETC transaction is completed, signing the encrypted transaction flow data by using an identity certificate corresponding to the road section owner, and uploading the signed transaction flow data to the block chain platform; and the block chain platform is used for packaging the signed transaction flow data into a data block, and adding the data block to the block chain after consensus of each block chain node. The technical problem that the right of ETC transaction flow data is difficult to confirm in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of ETC, in particular to an ETC data right confirmation system based on block chain technology. Background technique [0002] When an ETC vehicle passes through the toll lane of the expressway or parking lot, the host computer reads the vehicle entrance and path information, calculates the toll amount, and deducts the OBU on the vehicle through the ETC antenna. After the deduction is successful, the vehicle information and the deduction transaction information It is packaged as transaction flow data in a certain format and uploaded to the ETC settlement center for subsequent fund settlement processes. [0003] With the development of the ETC industry, more and more toll deductions or routing information are generated when ETC vehicles pass through expressways. Through these transaction flow data, traffic flow and vehicle behavior habits can be analyzed, which is an important part of traffic big data....

AI Technical Summary

Problems solved by technology

However, due to the lack of technical means to confirm the data rights of these data, it is impossible to protect the rights and interests of road section owners in subsequent data applications and transactions

In addition, the current ETC transaction flow data only has the transaction content, without the identification content of the ETC antenna or the owner of the road section, which is easy to be copied and forged, and cannot be used as a certificate for data confirmation

[0004] It can be seen that the existing technology lacks a scheme for confirming the rights of ETC transaction flow data
