Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the 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 invention.
The services in intelligent parking are currently implemented based on a traditional centralized system. The transaction data of the user parking is directly stored in the database system of the parking lot, but the database system of the parking lot generally does not have the capability of safely maintaining the transaction data, and the transaction data is easily abused and leaked. Therefore, the safety of the processing process of the transaction data in the current intelligent parking service is poor, which is a problem to be solved urgently. Therefore, as shown in fig. 1, the present application provides a data processing method for intelligent parking based on a block chain.
Step 101: and the target parking lot node encrypts the transaction information in a preset encryption mode to obtain encrypted transaction data.
Step 102: and the target parking lot node sends the encrypted transaction data to a transaction processing node.
The transaction processing node meets a preset robustness criterion.
Step 103: and the target parking lot node acquires a transaction result from the transaction processing node, generates a block according to the encrypted transaction data and the transaction result, and writes the block into the target parking lot node.
In steps 101 to 103, the transaction result is obtained by executing the decrypted transaction information after the transaction processing node decrypts the encrypted transaction data by a preset decryption mode; the decrypted transaction information is obtained by decrypting the encrypted transaction data after the transaction processing node determines that the legality consensus of the plurality of consensus nodes on the encrypted transaction data passes; the target parking lot node, the transaction processing node and the plurality of consensus nodes are all nodes in a block chain.
In step 101 to step 103, the block chain may be a federation chain. The alliance node is mainly a parking lot service provider and comprises a traffic management department node and other credible nodes.
In an alternative embodiment, the transaction processing node and the plurality of consensus nodes are determined by:
if the target parking lot node does not have the appointed transaction processing node and/or the appointed consensus node is smaller than a preset quantity threshold value, the target parking lot node sends detection information to each block chain node; the target parking lot node acquires performance attribute information of each block chain node; and the target parking lot node determines the transaction processing node and/or the plurality of consensus nodes according to the performance attribute information of each block chain node and the preset robustness standard.
And each block chain node is at least one block chain node except the target parking lot node in the block chain.
It should be noted that the performance attribute information of any one block link node of each block link point may include the following items: the network speed of the block chain nodes, the workload of the block chain link points, the credibility of the block chain nodes (which can be preset, for example, the credibility of the nodes in the government department is higher), and the weight of the block chain link points (which can be preset, for example, the credibility of the nodes in the government department is higher).
It should be noted that there may be a plurality of transaction processing nodes, only one transaction processing node may be sent to the consensus node, or the plurality of transaction processing nodes all send the encrypted transaction data to the plurality of consensus nodes, and after the plurality of consensus nodes pass the validity consensus on the encrypted transaction data, the plurality of transaction processing nodes decrypt the encrypted transaction data in a preset decryption manner to obtain a plurality of decrypted transaction information; the plurality of transaction processing nodes respectively execute the plurality of decrypted transaction information to obtain a plurality of transaction results, the transaction results can be commonly known in the plurality of transaction processing nodes, and one transaction processing node sends the transaction results to the target parking lot node, or the transaction results are not commonly known in the plurality of transaction processing nodes and directly sent to the target parking lot node, and only one transaction result is reserved in the target parking lot node.
In a transaction processing node-based manner, a quantity threshold may also be set for the plurality of transaction processing nodes, and the transaction processing nodes are supplemented according to the performance attribute information of the blockchain node when the number of the plurality of transaction processing nodes is less than the quantity threshold.
Specifically, the target parking lot node determines the transaction processing node and/or the multiple consensus nodes according to the performance attribute information of each block link node and the preset robustness standard, and the determination may be as follows:
the target parking lot node acquires the comprehensive scoring value of each block chain node according to the performance attribute information of each block chain node; determining the transaction processing nodes and/or the multiple consensus nodes from the block chain nodes meeting the preset robustness standard in the block chain nodes, and if the number of the block chain nodes meeting the preset robustness standard is M + N, taking the first M block chain nodes as multiple transaction nodes and taking the last N block chain nodes as multiple consensus nodes; m and N are positive integers.
Further, an embodiment is as follows:
if the appointed transaction processing node exists in the target parking lot node and the appointed consensus node is not smaller than the preset quantity threshold value, the target parking lot node sends detection information to the appointed transaction processing node and/or the appointed consensus node; the target parking lot node acquires the performance attribute information of the appointed transaction processing node and/or the performance attribute information of the appointed consensus node; and the target parking lot node deletes the block chain link points which do not accord with the preset robustness standard in the appointed transaction processing node and/or the appointed consensus node according to the performance attribute information of the appointed transaction processing node and/or the performance attribute information of the appointed consensus node.
Referring to the situation that the target parking lot node has no designated transaction processing node and/or the designated common identification node is smaller than the preset number threshold, the designated transaction processing node and/or the designated common identification node may also be deleted according to the comprehensive score value, and details are not repeated herein.
In an optional implementation manner, the target parking lot node obtains the data of the set query service by setting an intelligent contract of the query service.
The data of the set query service is transaction data and preset query data; the preset query data is kept consistent in each node of the block chain.
It should be noted that, in a specific structure, the transaction data and the protocol information followed by the transaction data are written into the blocks, and the storage is recorded in a block chain mode so as to maintain distributed consistency. Specifically, the preset query data may include user status data (data indicating whether the user is a smart parking, data requiring user binding), parking lot description data, and vehicle status data to ensure distributed consistency. The data are encrypted and stored according to a certain rule, and the data are ensured not to be abused by setting intelligent contract access provided by query service.
In an alternative embodiment, the user may bind according to the following steps:
and the target parking lot node acquires a user binding request.
And the target parking lot node displays indication information in a front-end page according to the user binding request. The indication information is used for indicating a user to input the data to be bound.
And the target parking lot node acquires and encrypts the data to be bound input by the user to acquire encrypted data to be bound.
And the target parking lot node stores the encrypted data to be bound through a binding intelligent contract of the block chain.
And the target parking lot node broadcasts the encrypted data to be bound to other nodes in the block chain.
Therefore, in the method shown in fig. 1, the use of the state information such as the block chain system maintenance protocol information, the vehicle information, and the entry information does not cause many invalid requests. Further, a transaction processing node and a consensus node are selected for a period of time based on a consensus algorithm, preventing transaction failures due to robustness issues. The method shown in fig. 1 can cover more conventional processes, reduce the development cost of the parking lot, and ensure the stability of each node; the information security risk is reduced by schemes of encrypting private transactions, intelligent contract management data and the like. With the increase of access parties, the system scheme is continuously perfected, and finally the degree that the access parties are free from development and direct use can be achieved, so that the access willingness of the parking lot can be improved, and the robustness of the system is guaranteed.
Correspondingly, the transaction processing node also has steps similar to those of the target parking lot node, which are as follows:
the transaction processing node obtains encrypted transaction data from the target parking lot node.
And the transaction processing node sends the encrypted transaction data to a plurality of consensus nodes.
And after the transaction processing node determines that the plurality of consensus nodes pass the legality consensus of the encrypted transaction data, the transaction processing node decrypts the encrypted transaction data in a preset decryption mode to obtain decrypted transaction information.
And the transaction processing node executes the decrypted transaction information, obtains a transaction result and sends the transaction result to the target parking lot node.
The encrypted transaction data is obtained by encrypting transaction information by the target parking lot node in a preset encryption mode; the transaction processing node meets a preset robustness criterion.
It should be noted that the method in fig. 1 is applicable to the system shown in fig. 2, and as shown in fig. 2, an embodiment of the present invention further provides a data processing system for intelligent parking based on a block chain, including: the system comprises a target parking lot node, a transaction processing node and a plurality of consensus nodes. Specifically, the method comprises the following steps:
and the target parking lot node is used for encrypting the transaction information in a preset encryption mode to obtain encrypted transaction data and sending the encrypted transaction data to the transaction processing node.
The transaction processing node meets a preset robustness criterion.
And the transaction processing node is used for sending the encrypted transaction data to the plurality of consensus nodes.
And the plurality of consensus nodes are used for realizing the legality consensus of the encrypted transaction data.
The transaction processing node is further configured to decrypt the encrypted transaction data in a preset decryption manner after the plurality of consensus nodes pass the legality consensus of the encrypted transaction data, so as to obtain decrypted transaction information; and executing the decrypted transaction information, obtaining a transaction result, and sending the transaction result to the target parking lot node.
The system shown in fig. 2 is a building of an intelligent parking system based on a block chain. The parking lot service provider can join the alliance chain with the parking lot node identity, and the government regulatory department can also choose to join. The front-end pages are respectively responsible for each node. The nodes may be grouped by city. In a public channel which is not a node own channel, a node responsible for a front-end page is selected based on a certain consensus algorithm, as shown in fig. 2. In the system shown in fig. 2, the data required to ensure distributed consistency may be: protocol chain, transaction chain (transaction data encryption), vehicle status data, user status data, parking lot data. The data stored by each node includes: vehicle entry information, transaction data (unencrypted). In the system, each node of the block chain is divided into a front terminal system, a rear terminal system and a communication subsystem in total. The front terminal system is the same as the traditional centralized system and provides functions of binding vehicles, signing an agreement, inquiring historical bills, inquiring nearby parking lots, viewing admission information and the like for a user; the back terminal system can be divided into a transaction module, an intelligent contract module, a data module and a management module. The communication system provides a communication function between the front-end subsystem and the rear-end subsystem and between different nodes. The system modules are shown in fig. 3.
The transaction module is mainly responsible for authenticating the request node when receiving the transaction; encrypting and decrypting the private transaction; and the consensus node performs consensus on the transaction data and executes the privacy transaction.
The intelligent contract module provides an intelligent contract access interface (API); the account book accesses the API; acquiring a trusted (recommended) node API; a subscription API and a signature encryption API.
The data module comprises subscription data; transaction data; user status data; parking lot data; vehicle ingress and egress data.
The management module is responsible for managing the access of the member nodes; distributing and modifying the signature encryption key of each member node; and distributing and modifying the authority of each node when calling the intelligent contract API. In particular, the following interfaces may be included:
binding state query interface: because the vehicle binding state is stored locally, the parking lot can freely select to carry out state query when entering or leaving, and inconvenience caused by network fluctuation and the like does not need to be worried. Meanwhile, the user data is encrypted and stored, and the content allowed by the node authority can be obtained only through an intelligent contract without worrying about the overuse of the parking lot.
In (out) field notification interface: the in-out interface has two functions in the original system design: firstly, show the information parking amount of money of registering and restrict the user and unbundle in the scene for the user, the user unbundles in the scene if the state synchronization can lead to earlier the parking area of lifting the pole to appear the short money, keeps in the parking area local along with the state of binding, and the function of restricting unbundling is no longer necessary. Secondly, the user can conveniently carry out active payment (according to the previous investigation and the actual situation, the parking lot providing the active payment is less). In the system, the distributed consistency of the vehicle entering and leaving data is not required to be ensured, otherwise, the waste of a large amount of invalid data stored by a centralized system is not completely solved, and the vehicle entering and leaving data only can be stored by a service provider node to which a parking lot belongs. If the user enters from the page of the current node, the user can directly check local data, and if the user enters from the page of the non-current node, the user can inquire the corresponding node by positioning and comparing the parking lot data stored in each node (optionally, the nodes in the same city can be grouped for data synchronization, the data is accessed by a smart contract to prevent each node from abusing the data, and the historical entrance and exit data of the node to which the non-data belongs is not stored to prevent resource waste).
Payment (refund) interface: and selecting transaction processing nodes and consensus nodes at intervals based on a consensus algorithm (for example, if a traffic management department joins the alliance chain as a node and the performance reaches the standard, the traffic management department node is preferentially used for processing transactions, if no credible third party node such as a government and the like exists, a free node with rich resources is used, each node can also designate part of credible nodes as own transaction processing nodes, and the nodes with higher credibility are selected as transaction consensus nodes). The transaction initiating node encrypts the transaction information and sends the encrypted transaction information to the transaction processing node, and after the transaction processing node and the consensus node achieve consensus, the encrypted transaction is decrypted and processed by using the agreed secret key. And the encrypted transaction data and the transaction result generation block are added into the transaction main chain. The method and the device ensure that only the initiating node and the transaction processing node have non-encrypted data for the private transaction and other nodes cannot abuse the data.
The payment result query interface shares the transaction result with all nodes, and only the data of the local area needs to be queried if the payment result needs to be queried.
