Blockchain-based method and system for processing traffic violation event

1. A blockchain-based method for processing a traffic violation event, comprising the following steps:

obtaining traffic violation reporting information provided by a first vehicle node stored in a blockchain;

obtaining an associated evidence data identifier in the traffic violation reporting information;

obtaining, according to the evidence data identifier, evidence data provided by a second vehicle node stored in the blockchain;

determining, according to the traffic violation reporting information and the associated evidence data, whether the traffic violation reporting information is valid;

determining, according to the traffic violation reporting information and the associated evidence data, whether the traffic violation reporting information is valid;

determining whether a quantity of second vehicle nodes providing the associated evidence data is greater than or equal to a preset first threshold, if the quantity of second vehicle nodes providing the evidence data is less than the preset first threshold;

identifying vehicle identification information in the traffic violation reporting information, and after anonymous processing is performed on the vehicle identification information, sending the traffic violation reporting information obtained after anonymous processing to an event auditor terminal; and

determining validity of the traffic violation reporting information according to an auditing result of the event auditor terminal.

2. The blockchain-based method for processing a traffic violation event according to claim 1 , wherein if the quantity of second vehicle nodes providing the evidence data is less than the preset first threshold, sending the traffic violation reporting information to a plurality of event auditor terminals; and

the determining validity of the traffic violation reporting information according to an auditing result of the event auditor terminal comprises the following steps:

determining whether a quantity of received auditing results of traffic violation confirmation is greater than a preset second threshold; and

if yes, determining that a traffic violation event in the traffic violation reporting information is valid; or

otherwise, determining that a traffic violation event in the traffic violation reporting information is invalid.

3. The blockchain-based method for processing a traffic violation event according to claim 1 , wherein the traffic violation reporting information comprises traffic violation event information, information about a vehicle in traffic violation, and an associated evidence data identifier, the evidence data comprises an evidence data identifier, traffic violation event information, and information about a vehicle in traffic violation that are of the evidence data, and the traffic violation event information comprises at least one of a traffic violation event time, a traffic violation event position, and a traffic violation event type.

4. The blockchain-based method for processing a traffic violation event according to claim 3 , wherein the method further comprises the following steps:

collecting, by the first vehicle node, a road image, and sending a proving request to the second vehicle node when a traffic violation event is detected in the road image, the proving request comprising information about a to-be-proved vehicle in traffic violation and information about a to-be-proved traffic violation event;

collecting, by the second vehicle node receiving the proving request, an image of the to-be-proved vehicle in traffic violation, and determining whether there is a traffic violation event consistent with the proving request;

if yes, storing, by the second vehicle node, the evidence data in the blockchain, and sending the evidence data identifier to the first vehicle node; and

storing, by the first vehicle node, the traffic violation reporting information in the blockchain.

5. The blockchain-based method for processing a traffic violation event according to claim 4 , when the first vehicle node stores the traffic violation reporting information in the blockchain, comprising: after encrypting information about the first vehicle node in the traffic violation reporting information using a private key, storing, by the first vehicle node, the traffic violation reporting information in the blockchain.

6. The blockchain-based method for processing a traffic violation event according to claim 1 , after the determining that the traffic violation reporting information is valid, further comprising the following steps:

counting a quantity of second vehicle nodes providing an evidence material; and

allocating, according to a preset point allocation rule for vehicle reporting and vehicle proving, award points to the first vehicle node and the second vehicle node that provides the evidence material.

7. The blockchain-based method for processing a traffic violation event according to claim 1 , after the determining that the traffic violation reporting information is valid, further comprising the following steps:

processing a vehicle in traffic violation according to a preset traffic violation processing rule and storing a processing result in the blockchain.

8. A blockchain-based system for processing a traffic violation event configured to implement the blockchain-based method for processing a traffic violation event according to claim 1 , wherein the system comprises:

a reporting information obtaining module configured to obtain traffic violation reporting information provided by a first vehicle node stored in a blockchain;

an evidence data obtaining module configured to: obtain an associated evidence data identifier in the traffic violation reporting information, and obtain, according to the evidence data identifier, evidence data provided by a second vehicle node stored in the blockchain; and

a reporting information determining module configured to determine, according to the traffic violation reporting information and the associated evidence data, whether the traffic violation reporting information is valid.
