Description

Traffic accident handling method, device and equipment based on block chain and storage medium

Technical Field

The present disclosure relates to the field of block chains, and in particular, to a method, an apparatus, a device, and a storage medium for handling a traffic accident based on a block chain.

Background

With the increasing number of automobiles, the density of vehicles running on roads is increased, and the probability of traffic accidents is gradually increased. At present, after a traffic accident occurs, the main processing mode is that a traffic police goes to an accident scene, and by inquiring the condition of a party, the traffic police performs responsibility confirmation by combining with part of evidence such as a vehicle data recorder, a mobile phone video or a monitoring video, and then performs processes such as sanction punishment or damage compensation mediation according to the responsibility confirmation result.

However, in the conventional traffic accident handling method, the accident scene needs to be protected while waiting for the traffic police to go to the accident site. This may cause the road where the accident occurs to have slow traffic or even congestion. Especially during peak vehicle driving periods, follow-up handling of traffic accidents together may cause extensive congestion. And when the person is in time or does not want to influence the passing of other vehicles, the negotiation process is generally selected for minor accidents such as slight scratch and the like. However, the negotiation process is not responsible for accidents, and thus the legal disputes are very many. Meanwhile, when an accident occurs, evidences recorded by equipment such as a vehicle event recorder, a mobile phone video recorder or a monitoring video are very easy to intercept and tamper, so that the distortion of field information is very easy to cause, the difficulty of determining the responsibility of the traffic accident is further increased, and the traffic accident handling process is more complicated.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The traffic accident processing method based on the block chain provided in the embodiment of the application is mainly characterized in that a plurality of parties including a block chain platform, a user node, an equipment node and a processing mechanism node are matched to realize a traffic accident processing process, namely, the user node is used for generating an accident processing request and transmitting the accident processing request to the block chain platform, the equipment node is used for acquiring evidence data and transmitting the evidence data to the block chain platform, the processing mechanism node is used for generating a processing scheme according to the evidence data and transmitting the processing scheme to the block chain platform, so that the user node acquires the processing scheme, and the block chain platform enables all the participating parties to be accommodated in the same block chain to realize data interaction of all the parties and link various data to the block chain in the accident processing process. The following embodiments describe a block chain based traffic accident handling method from a number of different perspectives.

In one embodiment, as shown in fig. 1, when the method for handling a traffic accident based on a block chain is applied to a block chain platform, the method includes the following steps:

step 101, receiving an accident handling request transmitted by a user node, linking the accident handling request to a block chain, and broadcasting the accident handling request in the block chain.

In one embodiment, after a traffic accident occurs, the user node generates an accident handling request for the traffic accident, uploads the accident handling request to the blockchain platform, and broadcasts the accident handling request in the blockchain. And after receiving the accident handling request, the handling mechanism node receives the accident handling request.

In this embodiment, after receiving the accident handling request, the blockchain platform links the accident handling request to the blockchain for storage, so as to ensure that the accident handling request is not deleted or modified.

In one embodiment, the user node is one or more public cloud nodes used in a unified manner, that is, a plurality of end users may connect to the same interface to access the blockchain platform through an interface connection or the like. When a traffic accident occurs and a party user uploads an accident handling request through a corresponding interface, the block chain platform acquires identity information of the user and verifies the identity information. After the verification is passed, the identity information and the accident handling request are linked together to a block chain for storage for subsequent use.

In this embodiment, the identity information of the user may be related information that the user registers autonomously, or may also be terminal information of a terminal used by the user, or other information according to needs and practical situations, and the protection scope of the present application is not limited by specific content of the identity information.

In one embodiment, the accident handling request includes information about the extent to which the traffic accident occurred. The range information may be location information and time information, for example, the range information may be a range corresponding to a first location radius within 50 meters, 12 pm to 12 pm on the day, or other information that may indicate a range. When the accident handling request is broadcasted in the block chain, other nodes verify the accident handling request, and after the equipment nodes in the range information verify the accident handling request, the evidence data related to the traffic accident is transmitted to the block chain platform.

In this embodiment, the devices within a certain range can be determined according to the range information, so that the devices irrelevant to the traffic accident are prevented from being called, and the data irrelevant to the traffic accident is prevented from being uploaded, thereby avoiding the phenomena of resource waste, accident processing speed reduction and the like.

Step 102, obtaining evidence data transmitted by the equipment node, and linking the evidence data to a block chain, wherein the evidence data is obtained by the equipment node according to the accident handling request, and the evidence data is broadcasted in the block chain.

In one embodiment, the device node is also one or more public cloud nodes used in a unified manner, that is, a plurality of devices may be connected to the same interface to access the blockchain platform through an interface connection or the like. When the equipment node receives the accident handling request, the evidence data which is provided by the plurality of equipment and is relevant to the traffic accident can be obtained through the same interface. The equipment for providing evidence data can be various types of Internet of Things (IOT), such as a camera, a vehicle data recorder, a mobile phone, a sensor, and The like. Before uploading data, the accident handling request is verified, after the data is successfully verified, data uploading authorization is carried out, and corresponding authorization information is also linked to the block chain for storage. The authorization information comprises equipment information corresponding to the Internet of things equipment.

In one embodiment, the evidence data is a hash value of the traffic accident related evidence, wherein the related evidence includes at least one of video data, picture data, text data, voice data, and sensor data.

In this embodiment, the blockchain is difficult to store a large file, and is slow to read, especially a video file, etc., after hash processing is performed on large file data, the size of uplink data can be greatly reduced, corresponding related data is still stored offline, and when the related data needs to be recalled to check whether the data is tampered, only the related data needs to be hashed again to obtain a hash value, and the hash value is compared with the hash value on the chain.

Step 103, acquiring the processing scheme transmitted by the processing mechanism node, and linking the processing scheme to the block chain, wherein the processing scheme is generated by the processing mechanism node according to the evidence data, and the processing scheme is broadcasted in the block chain, so that the user node acquires the processing scheme.

In one embodiment, after the processing mechanism node obtains the evidence data, it may first determine whether the collected evidence data is sufficient to support the processing of the traffic accident, and when it is determined that the evidence data is available, complete the processes of on-line responsibility determination, division of compensation amount, deduction and the like according to the evidence data, and generate an on-chain processing scheme; and when the support is determined not to be possible, generating an on-site treatment scheme.

In one embodiment, the processing scheme is an on-chain processing scheme, wherein the on-chain processing scheme includes responsibility identification, sanction penalties, and damage compensation. Broadcasting the processing scheme in the blockchain so that after the user node acquires the processing scheme, the user node can check the specific content of the processing scheme and decide whether to complain or not, and when the user thinks that the processing scheme can accept the processing scheme without complaining, generating confirmation information; when the user considers that the processing scheme can not accept the required complaint, complaint information is generated. The block chain platform performs different processing according to specific information transmitted by the user node, specifically as follows:

when the confirmation information transmitted by the user node is acquired, linking the claim settlement institution node according to the confirmation information, wherein the claim settlement institution node is used for executing an on-chain processing scheme through a preset intelligent contract, an accident responsible person delivers the claim compensation on line and deducts the score, an accident victim obtains the claim compensation, and the claim settlement institution carries out corresponding claim compensation; after the complaint information transmitted by the user node is acquired, the complaint information is broadcasted in the block chain, so that the processing mechanism node acquires the complaint information.

In this embodiment, the specific content of the preset intelligent contract may be set manually or obtained through a preset algorithm, and the protection range of the present application is not limited by the specific setting mode of the preset intelligent contract.

In this embodiment, the confirmation information or the complaint information and the data of the execution process of the corresponding processing scheme are all linked to the blockchain for storage.

and step 203, acquiring the related data of the traffic accident, which is acquired according to the data calling request, so that the monitoring organization node acquires the related data, wherein the related data comprises an accident handling request, evidence data and a handling scheme.

In this embodiment, the monitoring organization node may be a fixed block chain node, which is convenient for the monitoring organization to monitor the traffic accident handling process and timely call the relevant data as the evidence when a legal dispute occurs. The related data may also include intermediate data generated during the traffic accident handling process, that is, any data related to the traffic accident on the block chain may be retrieved by the monitoring authority.

In one embodiment, the Blockchain platform may be a Blockchain as a Service (BaaS) platform. The BaaS platform is mainly responsible for bringing block chain link points of all participants into the same alliance chain and maintaining account book data together; meanwhile, an encryption and decryption protocol is used for chain data transmitted by each node in the block chain, and confidentiality and integrity of the data are guaranteed. The Protocol may use various protocols, for example, a hypertext Transfer Protocol over Secure Socket Layer (HTTPS), a hypertext Transfer Protocol (HTTP), a File Transfer Protocol (FTP), and the like, and the scope of protection of the present application is not limited by the specific implementation form of the Protocol.

In this embodiment, the underlying resource of the block chain is implemented by multiple deployment modes, which may be one or more of a public cloud, a private cloud, a physical machine, and a virtual machine, or may be other deployment modes capable of implementing related functions.
