In the description that follows, references to the terms "first \ second \ third" are intended merely to distinguish similar objects and do not denote a particular order, but rather are to be understood that the terms "first \ second \ third" may be interchanged under certain circumstances or sequences of events to enable embodiments of the invention described herein to be practiced in other than those illustrated or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1) Transactions (transactions), equivalent to the computer term "Transaction," include operations that need to be committed to a blockchain network for execution and do not refer solely to transactions in the context of commerce, which embodiments of the present invention follow in view of the convention colloquially used in blockchain technology.

for example, a deployment (deployment) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; the Invoke (Invoke) transaction is used to append records of the transaction in the blockchain by invoking the smart contract and to perform operations on the state database of the blockchain, including update operations (including adding, deleting, and modifying key-value pairs in the state database) and query operations (i.e., querying key-value pairs in the state database).

2) a Block chain (Blockchain) is a storage structure for encrypted, chained transactions formed from blocks (blocks).

for example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.

3) A Blockchain Network (Blockchain Network) incorporates new blocks into a set of nodes of a Blockchain in a consensus manner.

4) ledger (legger) is a general term for blockchains (also called Ledger data) and state databases synchronized with blockchains.

Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting fast query of the transactions in the blockchain.

5) Intelligent Contracts (Smart Contracts), also known as chain codes (chaincodes) or application codes, are programs deployed in nodes of a blockchain network, and the nodes execute the intelligent Contracts called in received transactions to perform operations of updating or querying key-value data of a state database.

6) Consensus (Consensus), a process in a blockchain network, is used to agree on transactions in a block among a plurality of nodes involved, the agreed block is to be appended to the end of the blockchain, and the mechanisms for achieving Consensus include Proof of workload (PoW, Proof of Work), Proof of rights and interests (PoS, Proof of equity (DPoS), Proof of granted of shares (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), and so on.

An exemplary application of the blockchain network provided by the embodiment of the present invention is described below, referring to fig. 1, fig. 1 is a schematic architecture diagram of a traffic management system 100 based on the blockchain network provided by the embodiment of the present invention, where the traffic management system 100 includes a blockchain network 200 (exemplarily shown to include a node 210-1 to a node 210-3), a trusted law enforcement background 300, and clients 400/410, which are described below respectively.

the type of blockchain network 200 is flexible and may be, for example, any of a public chain, a private chain, or a federation chain. Taking a public link as an example, a client running on an electronic device (e.g., a user terminal and a server) of any service agent can access the blockchain network 200 without authorization; taking a federation chain as an example, a client operated by an electronic device (e.g., a terminal/server) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 200, and at this time, the service entity becomes a special node in the blockchain network 200, i.e., a client node.

note that the client node may provide only functionality that supports the initiation of transactions by the business entity (e.g., for uplink storage of data or for querying of data on the chain), and may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity) for the functionality of the conventional (native) node 210 of the blockchain network 200, such as the ranking functionality, consensus services, ledger functionality, etc., described below. Therefore, the data and the service processing logic of the service subject can be migrated into the block chain network 200 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the block chain network 200.

Blockchain network 200 receives a submitted transaction from a business entity (e.g., trusted law enforcement backend 300 shown in fig. 1), executes the transaction to update or query the ledger, and displays various intermediate or final results of the executed transaction in a user interface of the client.

An exemplary application of the blockchain network is described below with an example of a service agent accessing the blockchain network to implement traffic management.

referring to fig. 1, trusted law enforcement back office 300 may access blockchain network 200 after authorization is obtained. The user registers identity information through the client 400, and the identity information of the user is sent to the trusted law enforcement background 300; the trusted law enforcement backend 300 verifies the identity information of the user, and after the verification is passed, the trusted law enforcement backend 300 generates a transaction corresponding to the updating operation/the query operation according to the identity information of the user/the identity information query request of the user, an intelligent contract required to be called for realizing the updating operation/the query operation and parameters transmitted to the intelligent contract are specified in the transaction, the transaction also carries a digital signature signed by the trusted law enforcement backend 300 (for example, a summary of the transaction is encrypted by using a private key in a digital certificate of the trusted law enforcement backend 300), and the transaction is broadcasted to the blockchain network 200.

when the node 210 in the blockchain network 200 receives the transaction, the digital signature carried by the transaction is verified, after the digital signature is successfully verified, whether the trusted law enforcement background 300 has the transaction authority is determined according to the identity information of the trusted law enforcement background 300 carried in the transaction, and the transaction failure is caused by the verification failure of any one of the digital signature and the authority verification. After successful verification, node 210 signs its own digital signature (e.g., by encrypting the digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After the node 210 with the sorting function in the blockchain network 200 receives the transaction successfully verified, the transaction is filled into a new block and broadcasted to the node providing the consensus service in the blockchain network 200.

The node 210 providing the consensus service in the blockchain network 200 performs the consensus process of verifying the new block to reach agreement, the node 210 providing the ledger function appends the new block to the tail of the blockchain, and performs the transaction in the new block: for the transaction of submitting the updated user identity information, updating the key value pair corresponding to the user identity information in the state database; and for the transaction of inquiring the identity information of the user, inquiring the key value pair corresponding to the identity information of the user from the state database, and returning an inquiry result.

then, the user uploads the traffic information to the trusted law enforcement background 300 through the client 400, the trusted law enforcement background 300 authenticates the user submitting the traffic information according to the identity information stored in the blockchain network 200, and performs traffic violation verification on the traffic information submitted by the authenticated user to obtain a verification result of the traffic information. The trusted law enforcement background 300 generates a transaction corresponding to the updating operation/the query operation according to the traffic information/the traffic information query request and the audit information/the audit information query request, specifies an intelligent contract required to be called for realizing the updating operation/the query operation and parameters transmitted to the intelligent contract in the transaction, carries a digital signature signed by the trusted law enforcement background 300, and broadcasts the transaction to the blockchain network 200.

the node 210 providing the consensus service in the blockchain network 200 performs the consensus process on the new block to reach an agreement, the node 210 providing the ledger function appends the new block to the tail of the blockchain, and performs the transaction in the new block: updating key value pairs corresponding to the traffic information/audit results in the account book database for the transaction of submitting the updated traffic information/audit results; and for the transaction of inquiring the traffic information/the checking result, inquiring the key value pair corresponding to the traffic information/the checking result from the account book database, and returning the inquiring result.

the trusted law enforcement background 300 receives a transaction identifier which is returned by the blockchain network 200 and stores the identity information of the user; and associating the transaction identifier of the identity information of the user with the corresponding auditing result, and returning the auditing result to the corresponding user through the client 400.

It is understood that the type of data that can be queried/updated by the service entity in the blockchain network 200 may be implemented by restricting the authority of the transaction that can be initiated by the service entity, for example, when the trusted law enforcement backend 300 has the authority to initiate the transaction for querying traffic information, the user may send a violation query request to the trusted law enforcement backend 300 through the client 410, and generate a transaction broadcast for querying the violation request by the trusted law enforcement backend 300 into the blockchain network 200, so as to obtain corresponding traffic information from the blockchain network 200.

as an example, the client 400 and the client 410 described above may have both a function of uploading traffic information and a function of querying a violation record; the client 400 and the client 410 may also be clients with different functions, for example, the client 400 has a function of uploading traffic information, and the client 410 has a function of querying violation records).

An exemplary functional architecture of a block chain network provided in an embodiment of the present invention is described below, referring to fig. 2, fig. 2 is a functional architecture schematic diagram of a block chain network 200 provided in an embodiment of the present invention, which includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, which are described below respectively.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 210 in the blockchain network 200, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism and service agent identity management.

Wherein the P2P network protocol implements communication between nodes 210 in the blockchain network 200, the data propagation mechanism ensures propagation of transactions in the blockchain network 200, and the data verification mechanism implements reliability of data transmission between nodes 210 based on cryptography methods (e.g., digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service subject added into the block chain network 200 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 200 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access blockchain network 200, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functions of the mechanism for the nodes 210 in the blockchain network 200 to agree on a block (i.e., a consensus mechanism), transaction management, and ledger management.

The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is configured to verify a digital signature carried in the transaction received by the node 210, verify identity information of the service entity, and determine whether the node has an authority to perform the transaction (read related information from the identity management of the service entity) according to the identity information; for the service agents authorized to access the blockchain network 200, the service agents all have digital certificates issued by the certificate authority, and the service agents sign the submitted transactions by using private keys in the digital certificates of the service agents, so that the legal identities of the service agents are declared.

Account book management: for maintaining blockchains and state databases. For the block with the consensus, adding the block to the tail of the block chain; and executing the transaction in the acquired consensus block, updating the key-value pairs in the state database when the transaction comprises an updating operation, inquiring the key-value pairs in the state database when the transaction comprises an inquiring operation, and returning an inquiring result to the business body.

The following describes an embodiment of the present invention in further detail with reference to the accompanying drawings. Referring to fig. 4, fig. 4 is a flowchart illustrating a traffic management method based on a blockchain network according to an embodiment of the present invention, and will be described with reference to the steps shown in fig. 4.

In step S101, the trusted law enforcement background receives identity information of a user sent by a client.

In some embodiments, the user registers personal identity information in the client, and the trusted law enforcement back office receives the identity information of the user sent by the client, wherein the identity information of the user may include: name, resident identification number, mobile phone number, home address, vehicle identification belonging to the user, face information of the user and the like.

In step S102, the trusted law enforcement back office authenticates the identity information of the user.

In some embodiments, the trusted law enforcement back office may invoke an interface of an authentication function (e.g., a household authority) to verify the identity information of the user.

as an example, the trusted law enforcement back office 300 may invoke an interface of a household management department, which verifies the identity information by querying the identity information of the user stored by the household management department, for example: and verifying whether the name uploaded by the user corresponds to the resident identification number one by one, and when the name uploaded by the user corresponds to the resident identification number, the trusted law enforcement background 300 can obtain the confirmation that the authentication is passed from the interface of the household registration management department.

In step S103, the trusted law enforcement back office stores the identity information of the user in the blockchain network after the authentication is passed.

In some embodiments, the blockchain network is a public chain, and before step S102, the trusted law enforcement back office may directly access the blockchain network, and the trusted law enforcement back office may freely participate in reading and writing data on the chain.

In other embodiments, the blockchain network is a federation chain, and before step S102, the trusted law enforcement back office requests access to the blockchain network, and receives a digital certificate assigned by the blockchain network to the trusted law enforcement back office, where the digital certificate is used to sign a digital signature with identity information for a user to be sent, so as to declare the identity information of the trusted law enforcement back office to the blockchain network.

as an example, the trusted law enforcement back office 300 generates a key pair by itself, where the key pair includes a public key and a private key, and sends the generated public key to the blockchain network 200, so that a node in the blockchain network 200 having a Certificate Authority (CA) function, that is, the CA node, sends a digital Certificate including the public key to the trusted law enforcement back office 300, where the digital Certificate carries a digital signature signed by the CA node for the public key and the identity information of the trusted law enforcement back office 300, and the digital signature is obtained by the CA node by encrypting with its private key, the public key of the trusted law enforcement back office 300, and the identity information. When the trusted law enforcement background 300 subsequently sends identity information to the blockchain network 200, the trusted law enforcement background carries the digital certificate issued by the CA node. For the digital signature of the information to be saved, after receiving the information, the nodes in the blockchain network 200 sequentially verify the digital certificate and the digital signature to determine the identity of the trusted law enforcement background 300 that sent the information to be saved and the reliability of the information to be saved. When the verification is successful, the information to be saved is saved in the blockchain network 200. When the authentication fails, a denial message (e.g., lack of authority) is returned to the trusted law enforcement back office 300, wherein the trusted law enforcement back office 300 may be a node belonging to a traffic authority (e.g., a traffic police center, a police department of provincial or prefectural municipality, etc.).

Of course, the above-mentioned CA node may also be replaced with a CA authority of a third party.

in some embodiments, the trusted law enforcement back office invokes an interface of an authentication function (e.g., a household management department) to authenticate the identity information of the user; when the interface is confirmed to pass the authentication, the hash value of the original data of the user identity or the original data representing the user identity is stored in the blockchain network.

In some embodiments, the trusted law enforcement back office sends the user identity information to a node belonging to the authentication function in the blockchain network, so that the node of the authentication function generates a new block based on the received user identity information, and when a consensus is obtained for authentication of the identity information in the new block (e.g., whether there is a record of a corresponding user, no traffic violation record, no bad credit record), the new block with the obtained consensus is added to the tail of the blockchain maintained by the node belonging to the authentication function. The nodes of the non-identity information verification functional mechanism in the blockchain network can synchronize blockchains only with the nodes of the traffic violation verification functional mechanism without participating in the node consensus process of the traffic violation verification functional mechanism. Therefore, the deployment cost of the non-identity information verification functional mechanism is reduced, and the network complexity is reduced.

In step S104, the trusted law enforcement back office receives the traffic information sent by the client.

In some embodiments, when the user finds that the vehicle has a traffic violation, the user may acquire traffic information through the client and send the traffic information to the trusted law enforcement background, where the traffic information may include data such as video, photos, or words.

As an example, when a user finds an illegal vehicle, such as illegal parking, reverse running, red light running, and the like, the user may use the client 400 to perform 360-degree shooting with reference to illegal shooting standards under the condition of ensuring the security of the user, the client 400 may automatically add information watermarks such as time and position to the shot video to ensure the legality/compliance of the shot video, and finally the user uploads the shot video to the trusted law enforcement background through the client.

In step S105, the trusted law enforcement back office authenticates the user submitting the traffic information according to the stored identity information in the blockchain network.

In some embodiments, the trusted law enforcement background acquires identity information of a user submitting traffic information, verifies the identity information of the user submitting the traffic information according to the identity information which is stored in the blockchain network and passes authentication, and passes authentication when the identity information of the user submitting the traffic information belongs to the identity information which is stored in the blockchain network and passes authentication; and when the identity information of the user submitting the traffic information does not belong to the stored identity information which passes the authentication in the blockchain network, the authentication does not pass.

The embodiment of the invention can ensure high reliability of the traffic information submitted by the user by authenticating the user submitting the traffic information, and can save auditing resources when the traffic information is audited for traffic violation in the follow-up process.

In step S106, the trusted law enforcement background performs a traffic violation audit on the traffic information submitted by the authenticated user, so as to obtain an audit result of the traffic information.

in some embodiments, the trusted law enforcement back office identifies vehicle identification, vehicle behavior, time information, and location information in the traffic information; when the vehicle behavior is determined to be not in accordance with the traffic regulations, generating an auditing result representing the violation of the traffic information based on the vehicle identification, the vehicle behavior, the information, the location information and the violation type; and when the vehicle behavior is determined to be in accordance with the traffic regulations, generating an auditing result representing that the traffic information is not violated based on the vehicle identification, the vehicle behavior, the information, the location information and the type of non-violation.

As an example, the trusted law enforcement back office 300 may extract information such as vehicle identification, vehicle behavior, time and location from traffic information submitted by authenticated users through artificial intelligence and deep image recognition technology. When the vehicle behavior does not conform to the traffic regulations (such as illegal parking, inverse traveling and red light running, and the like), generating an auditing result representing the violation of the traffic information; when the vehicle behavior conforms to the traffic regulations, an audit result is generated which indicates that the traffic information does not violate the regulations.

In step S107, the trusted law enforcement back office saves the traffic information and the audit result in the blockchain network.

In some embodiments, the hash value of the traffic information and the hash value of the audit result are determined, and the hash value of the traffic information and the hash value of the audit result are stored in the block chain network; or, storing the traffic information and the original data of the auditing result in the block chain network.

According to the embodiment of the invention, when the traffic information and the auditing result data volume are small, the original data of the traffic information and the original data of the auditing result are stored in the block chain network, so that the stored data can be conveniently read subsequently; when the traffic information and the audit result have large data volume, the hash value of the traffic information and the hash value of the audit result are stored in the block chain network, so that the storage space of the block chain network can be saved.

In some embodiments, the traffic information and the audit result are sent to a node belonging to a traffic violation audit function in the blockchain network, so that the node generates a new block based on the received traffic information and the audit result, and when a consensus is verified for the traffic information and the audit result in the new block, the consensus-obtained new block is added to the tail of the maintained blockchain. The nodes of the non-traffic violation auditing function mechanism in the blockchain network can synchronize blockchains only with the nodes of the identity information verification mechanism without participating in the node consensus process of the identity information verification mechanism. Therefore, the deployment cost of the non-traffic violation auditing functional mechanism is reduced, and the network complexity is reduced.

In step S108, the trusted law enforcement background associates the audit results with the corresponding identity information of the user respectively.

In some embodiments, the trusted law enforcement back office receives a transaction identifier, returned by the blockchain network, storing identity information of the user; and associating the transaction identification of the identity information of the user with the corresponding auditing result. The transaction identifier storing the identity information of the user may be a hash of a transaction in which the blockchain network stores the identity information of the user. For example, as shown in fig. 9C, there will be a hash of each corresponding transaction in the blockchain network, where the hash of the transaction is a character string composed of 64-bit characters and has uniqueness, for example: 0x28b87aa213f3a591bf8e8c05b3af3939e0e6219d204e5451e63c398a1f6b 2228.

In step S109, the trusted law enforcement back returns the audit result to the client of the corresponding user.

In some embodiments, the trusted law enforcement back office returns the audit result of the traffic information to the client of the corresponding user according to the information that the audit result is associated with the identity information of the corresponding user, and when the traffic information submitted by the user is audited as a traffic violation, the trusted law enforcement back office may send the audit result to the user and, at the same time, may send, to the user, a credit that can be redeemed for rights and interests from within the blockchain network or outside the blockchain network.

in some embodiments, in step S106, when the vehicle behavior does not conform to the traffic regulations (e.g., parking violation, backward traveling, running red light violation, etc.), and the trusted law enforcement back office generates an audit result representing the violation of the traffic information, the trusted law enforcement back office determines the vehicle identifier in the traffic information and invokes an interface of a traffic management department, and the traffic management department determines personal information (e.g., name, mobile phone number, identification number, etc.) of the vehicle owner corresponding to the vehicle identifier in the traffic information according to the vehicle identifier stored by the traffic management department. The credible law enforcement background can acquire the personal information of the owner of the illegal vehicle from the traffic management department, and then inform the owner of the payment of fine and other matters of the illegal vehicle through short messages or telephones according to the personal information of the owner. Moreover, the related payment record information of the vehicle owner may also be saved in the blockchain network, and the related payment record information saved in the blockchain network may be used as a reference of a credit investigation institution (for example, the credit investigation structure may be accessed in the blockchain network, and used as an observation node to acquire the related payment record information).

Taking the client 400 and the client 410 as different clients as an example to explain the process of querying the violation record, referring to fig. 5, fig. 5 is a flowchart of the traffic management method based on the blockchain network according to the embodiment of the present invention, and based on fig. 4, after step S109, steps S110 to S112 may be included.

in step S110, the trusted law enforcement back office responds to the violation query request.

By way of example, when a user sends a violation query request to trusted law enforcement backend 300 through client 410, the violation query request may include: identity information of the requesting user and/or a vehicle identification of the requesting user.

In step S111, the trusted law enforcement back office queries the traffic information stored in the blockchain network.

As an example, when the identity information of the requesting user is included in the violation query request, the trusted law enforcement backend 300 queries the traffic information corresponding to the identity information stored in the blockchain network 200 according to the identity information of the requesting user.

as an example, when the violation inquiry request includes the vehicle identifier to be inquired, the trusted law enforcement back office 300 inquires the traffic information of the corresponding vehicle identifier stored in the blockchain network 200 according to the vehicle identifier to be inquired.

In step S112, the trusted law enforcement back office returns the violation query result according to the queried traffic information.

As an example, the trusted law enforcement back office 300 sends queried traffic information to the corresponding client 410, where the queried traffic information includes information such as vehicle identification, vehicle behavior, time and place. When the user does not recognize the queried traffic information, the trusted law enforcement back office 300 can be applied for a review through the client 410. When a user applies for a review (without approval for the queried traffic information) to the trusted law enforcement background 300 through the client 410, the trusted law enforcement background 300 verifies the traffic information queried by the user for the review of the user, and re-audits the traffic information queried by the user, and if the audit result of the traffic information queried by the user changes, the trusted law enforcement platform 300 needs to re-submit the changed audit result to the blockchain network 200.

Referring to fig. 6, fig. 6 is a flowchart illustrating a traffic management method based on a blockchain network according to an embodiment of the present invention, and based on fig. 4, step S113 may be included after step S108.

In step S113, when the traffic information submitted by the user is checked as a traffic violation, the trusted law enforcement back office sends the user credits that can be redeemed for rights and interests from within the blockchain network or outside of the blockchain network.

As an example, when the traffic information submitted by the user is checked to be a traffic violation, the trusted law enforcement back office sends a credit (which may be a blockchain credit) that can be redeemed for rights and interests from the blockchain network to the user, wherein a node belonging to the credit exchange mechanism accesses the blockchain network, owns the observation node, and when the user submits the traffic information and the checking result is saved in the blockchain network, the credit exchange mechanism can query the information. When the user has redeemed an entitlement through the client to the points redemption mechanism, the points redemption mechanism may submit a transaction (an update operation that gives the user the points) to the blockchain network.

As an example, when the traffic information submitted by the user is reviewed as a traffic violation, the trusted law enforcement back office sends the user credits that can be redeemed for equity from outside the blockchain network. The block chain network does not include nodes belonging to the point exchange mechanism, and the point exchange mechanism cannot interact with the block chain network but can interact with a trusted law enforcement background. When the user has redeemed the equity to the points redemption mechanism through the client, the points redemption mechanism may send an instruction to the trusted law enforcement back office to reduce the user's points.

As an example, the user sends a point exchange request to a point exchange mechanism through the client, and the point exchange mechanism returns the user the benefits provided by the point exchange mechanism according to the points of the user, such as discount coupons, cash vouchers, tokens and the like, such as electronic coupons, commodity electronic exchange coupons and food electronic exchange coupons.

In the following, an exemplary application of the embodiments of the present invention in a practical application scenario will be described.

In the related technology, traffic management is mainly carried out by taking a snapshot of vehicles violating the road through a law enforcement snapshot camera and a traffic police, then uploading the vehicle violating the road to a traffic management department, and finally auditing violation information through manual registration.

However, the traffic management in the related art has several problems: firstly, the deployment cost is too high, the coverage area is limited, the snapshot can be carried out only at some traffic intersections, and the traffic violation occurrence rate cannot be well reduced. Secondly, the dependence on the network is too high, the network is easily influenced by environmental factors, and the phenomenon that the network cannot work normally occurs.

in view of the above problems, an embodiment of the present invention provides a traffic management method based on a block chain network, where citizens (i.e. the above-mentioned users) register and authenticate with real names on a client, and the client synchronizes with a national time service center in real time. When a vehicle violation behavior occurs, under the condition of ensuring the safety of the citizen, the citizen refers to the camera shooting standard through the mobile phone client, carries out 360-degree violation field camera shooting, extracts the data characteristics in the video through a technical means, and simultaneously records the occurrence time, space, position and other information in detail. And the illegal information (namely the traffic information) is subjected to uplink storage through a block chain technology, so that traceability and tamper resistance are realized.

Referring to fig. 7, fig. 7 is a schematic node diagram of a blockchain network in a traffic management system based on a blockchain network according to an embodiment of the present invention, which will be described in detail with reference to fig. 7.

According to different business scenes, a plurality of different accounts are supported, and the block chain nodes can be selected to join in a group according to business relations and participate in the data sharing and consensus process of the corresponding accounts. A mechanism A, B, C in fig. 7 represents a participant (e.g., a traffic police center, a police department, an operator or platform organization, etc.) in the traffic management system based on the blockchain network, and nodes (nodes 0 to 5 are exemplarily shown in fig. 7) may represent consensus nodes or observation nodes, wherein the consensus nodes may participate in data synchronization in the blockchain network, and the observation nodes can only inquire data in the blockchain network and cannot participate in data synchronization in the blockchain network. The consensus node and the observation node may be selected according to traffic requirements, for example: the node attributed to the traffic violation review function described above may be a consensus node.

Referring to fig. 8, fig. 8 is a schematic flowchart of a traffic management method based on a blockchain network according to an embodiment of the present invention. The description will be made in conjunction with the respective steps.

In step S202, the trusted mobile phone client uploads the information to the trusted law enforcement background for registration and storage.

In step S203, the trusted law enforcement background encrypts and uploads citizen information to be stored on the trusted block chain platform (i.e., the block chain network), so as to ensure that the privacy of the user is not leaked and ensure the security of the citizen privacy.

In step S204, when illegal vehicles, such as illegal parking and driving in the wrong direction, occur, and the citizen can ensure his own security, the trusted mobile phone client is turned on.

In step S205, citizens use the trusted mobile phone client to perform 360-degree shooting with reference to illegal shooting standards, and the trusted mobile phone client will automatically add information watermarks such as time and location to the shot video to ensure legal compliance of the shot video.

In step S206, the citizen uploads the captured video to the trusted law enforcement background through the trusted mobile phone client.

in step S207, the trusted law enforcement back office may extract information such as vehicle information, time, and location in the video through artificial intelligence and depth image recognition technology, and determine and confirm the violation of the vehicle.

In step S208, the trusted law enforcement background returns the result of the determination to the trusted mobile phone client of the citizen, and rewards the behavior of reporting the violation, such as points, so as to encourage the citizen to actively participate in the behavior of reporting the violation by the citizen, thereby improving the enthusiasm of citizen participation.

in step S209, the trusted law enforcement background uploads the determination result and the traffic information to the trusted block link platform for storage, so as to facilitate the retrenching of the illegal vehicle, and notifies the illegal vehicle of payment of fines and other items through a short message or a telephone.
