Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Currently, services in smart parking are implemented based on conventional centralized systems. The transaction data of the parking of the user is directly stored in the database system of the parking lot, however, the database system of the parking lot generally does not have the capability of safely maintaining the transaction data, and the abuse and the leakage of the transaction data are easily caused. Therefore, the security of the transaction data in the smart parking service is poor, which is a problem to be solved. To this end, as shown in fig. 1, the present application provides a data processing method for intelligent parking based on blockchain.
Step 101: the target parking lot node encrypts the transaction information in a preset encryption mode to obtain encrypted transaction data.
Step 102: the target parking lot node transmits 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 step 101 to step 103, the transaction result is obtained by executing the decrypted transaction information after the transaction processing node decrypts the encrypted transaction data in a preset decryption mode; the decrypted transaction information is obtained by decrypting after the transaction processing node determines that legal consensus of a 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 blockchain.
In step 101 to step 103, the blockchain may be a coalition chain. The alliance node is mainly based on parking lot service providers and comprises traffic management department nodes and other trusted nodes.
In an alternative embodiment, the transaction processing node and the plurality of consensus nodes are determined in the following manner:
If the target parking lot node does not have the designated transaction processing node and/or the designated consensus node is smaller than the preset number threshold, the target parking lot node sends detection information to each blockchain node; the target parking lot node acquires performance attribute information of each blockchain 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 blockchain node and the preset robustness standard.
Wherein each blockchain node is at least one blockchain node in the blockchain other than the target parking lot node.
It should be noted that, the performance attribute information of any blockchain node of the blockchain nodes may include the following items: the net speed of the blockchain node, the workload of the blockchain node, the degree of trustworthiness of the blockchain node (which may be preset, e.g., higher for nodes of a government agency), the weight of the blockchain node (which may be preset, e.g., higher for nodes of a government agency).
It should be noted that there may be a plurality of transaction processing nodes, which may be only one transaction processing node, or may all send the encrypted transaction data to a plurality of consensus nodes, and after the legitimacy consensus of the plurality of consensus nodes on the encrypted transaction data passes, the plurality of transaction processing nodes decrypt the encrypted transaction data by a preset decryption manner, so as to obtain a plurality of decrypted transaction information; the plurality of transaction processing nodes execute the decrypted transaction information respectively to obtain a plurality of transaction results, the transaction results can be commonly known in the transaction processing nodes, one transaction processing node transmits the transaction results to a target parking lot node, or the transaction processing nodes do not commonly know the transaction results, the transaction results are directly transmitted to the target parking lot node, and the target parking lot node only retains one transaction result.
Under the mode based on the transaction processing nodes, a quantity threshold value can be set for a plurality of transaction processing nodes, and under the condition that the quantity of the transaction processing nodes is smaller than the quantity threshold value, the transaction processing nodes are supplemented according to the performance attribute information of the blockchain nodes.
Specifically, 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 blockchain node and the preset robustness standard, and may be as follows:
the target parking lot node obtains the comprehensive grading value of each blockchain node according to the performance attribute information of each blockchain node; determining the transaction processing node and/or the plurality of consensus nodes from the blockchain nodes meeting the preset robustness standard in the blockchain nodes, wherein if M+N blockchain nodes meeting the preset robustness standard are used, the first M blockchain nodes are used as a plurality of transaction nodes, and the last N blockchain nodes are used as a plurality of consensus nodes; m and N are positive integers.
Further, one embodiment is as follows:
If the designated transaction processing node exists in the target parking lot node and the designated consensus node is not smaller than the preset quantity threshold, the target parking lot node sends detection information to the designated transaction processing node and/or the designated consensus node; the target parking lot node acquires performance attribute information of the designated transaction processing node and/or performance attribute information of the designated consensus node; and deleting the block chain nodes which do not accord with the preset robustness standard in the appointed transaction processing node and/or the appointed consensus node by the target parking lot 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 does not have a designated transaction processing node and/or the designated consensus node is smaller than the preset quantity threshold, the designated transaction processing node and/or the block chain node which does not meet the preset robustness standard in the designated consensus node can be deleted according to the comprehensive grading value, and the detailed description is omitted.
In an alternative embodiment, the target parking lot node obtains the data of the set query service through an intelligent contract of the set query service.
The data of the set query service are transaction data and preset query data; the preset query data remains consistent among nodes of the blockchain.
It should be noted that, in a specific structure, the transaction data and protocol information followed by the transaction data are written into the block, and are recorded and stored in a blockchain mode so as to keep distributed consistency. Specifically, the preset query data may include user status data (data indicating whether the user is smart parking or not, data requiring user binding), parking lot description data, vehicle status data, and guarantee distributed consistency. The data are encrypted and stored according to a certain rule, and are accessed by setting intelligent contracts provided by query service, so that the data are ensured not to be abused.
In an alternative embodiment, the user may bind as follows:
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 the user to input data to be bound.
And the target parking lot node acquires the data to be bound input by the user and encrypts the data to be bound to obtain encrypted data to be bound.
And the target parking lot node stores the encrypted data to be bound through the binding intelligent contract of the blockchain.
The target parking lot node broadcasts the encrypted to-be-bound data to other nodes in the blockchain.
Therefore, in the method shown in fig. 1, the state information such as protocol information, vehicle information, entrance information, etc. is maintained using the blockchain hierarchy, so that many invalidation requests are not caused. Further, a transaction processing node and a consensus node are selected for a period of time based on the consensus algorithm, preventing transaction failure due to robustness issues. The method shown in the figure 1 can cover more conventional processes, reduce the development cost of a parking lot and ensure the stability of each node; the information security risk is reduced through schemes such as encryption of 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 of direct use of the access parties without development can be achieved, so that the access wish of a parking lot can be improved, and the robustness of the system is ensured.
Accordingly, the transaction processing node also has steps similar to those of the target parking lot node, and the steps are as follows:
the transaction processing node obtains encrypted transaction data from the target parking lot node.
The transaction processing node transmits the encrypted transaction data to a plurality of consensus nodes.
After the transaction processing node determines that the legitimacy consensus of the plurality of consensus nodes on the encrypted transaction data is passed, 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 through a preset encryption mode by the target parking lot node; 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 blockchain, including: the system comprises a target parking lot node, a transaction processing node and a plurality of consensus nodes. Specifically:
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.
The transaction processing node is configured to send the encrypted transaction data to the plurality of consensus nodes.
The plurality of consensus nodes are used for consensus on the legality of the encrypted transaction data.
The transaction processing node is further configured to decrypt the encrypted transaction data through a preset decryption mode after legal consensus of the plurality of consensus nodes on the encrypted transaction data passes, so as to obtain decrypted transaction information; and executing the decrypted transaction information to obtain a transaction result, and sending the transaction result to the target parking lot node.
The system shown in fig. 2 is for building a smart parking system based on a blockchain. Parking lot service providers can join the alliance chain with parking lot node identities, and government regulators can also choose to join. The front page is respectively responsible for each node. Nodes may be grouped by city. In the public channel of the non-node self-owned channel, the node responsible for the front-end page is selected based on a certain consensus algorithm, and the node is specifically shown in fig. 2. In the system shown in fig. 2, the data needed 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 is: vehicle entrance information, transaction data (not encrypted). In the system, each node of the blockchain is divided into three parts, namely a front subsystem, a rear subsystem and a communication subsystem. The front subsystem is the same as the traditional centralization system, and provides functions of binding vehicles, signing agreements, inquiring historical bills, inquiring nearby parking lots, checking entrance information and the like for users; the rear subsystem may be divided into a transaction module, an intelligent contract module, a data module, and a management module. The communication system provides communication functions between the front and rear subsystems, different nodes. The system modules are shown in fig. 3.
The transaction module is mainly responsible for authenticating the request node when receiving transaction; encrypting and decrypting the private transaction; and the consensus node performs consensus on the transaction data and performs private transactions.
The smart contract module provides a smart contract access interface (API); the account book accesses an 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 in-out data.
The management module is responsible for managing the ingress and egress of member nodes; distributing and modifying signature encryption keys of each member node; and distributing and modifying the authority of each node when calling the intelligent contract API. Specifically, the following interfaces may be included:
Binding state query interface: because the binding state of the vehicle is stored locally, the parking lot can freely select to inquire the state when entering or exiting, and inconvenience caused by network fluctuation and the like is not needed to be worried. And meanwhile, the user data is stored in an encrypted mode, only the content allowed by the node authority can be acquired through the intelligent contract, and excessive use of a parking lot is not required.
In (out of) field notification interface: the in-and-out interface has two roles in the original system design: firstly, the parking amount of the entrance information is displayed for the user, the user is limited to unbind in the field, if the state of unbind in the field is not synchronous, the short money appears in the parking lot lifted first, and the unbind limiting function is not necessary any more along with the fact that the binding state is stored in the local parking lot. Secondly, the user can pay actively (according to the prior investigation and actual situation, the parking lot providing active payment is less). In the system, the data of the vehicle entering and leaving the parking lot does not need to ensure the distributed consistency, otherwise, the waste of the centralized system for storing a large amount of invalid data is not solved at all, and the data of the vehicle entering and leaving the parking lot is only stored by the service provider node of the parking lot. If the user enters from the page of the current node, the user can directly check the local data, if the user enters from the page of the non-current node, the user can check the parking lot data stored in each node to the corresponding node through positioning comparison (the nodes in the same city can be grouped for data synchronization in an optional mode, the data are accessed by the intelligent contract to prevent each node from abusing the data, and the historical entering and exiting data of the node to which the non-data belongs are not stored to prevent resource waste).
Payment (refund) interface: transaction processing nodes and consensus nodes are selected at intervals based on a consensus algorithm (for example, if a traffic department is taken as a node to join a alliance chain and the performance reaches the standard, the traffic department node is preferentially used for processing transactions, if no trusted third party node such as government is available, more abundant resources are used, and each node can also designate part of trusted nodes as own transaction processing 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 reach consensus, the encrypted transaction is decrypted and processed by using the agreed secret key. The encrypted transaction data and the transaction result generation block join the transaction backbone. The method ensures that only the initiating node and the transaction processing node of the private transaction have unencrypted data, and other nodes cannot misuse the data.
