Description
Technical Field
The invention relates to the technical crossing field of the Internet of things and block chain information, in particular to a traffic data uplink method and equipment of the Internet of things based on a block chain.
Background
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in a blockchain system. The blockchain is the underlying technology of bitcoin, like a database ledger, which records all transaction records. The system is characterized in that a plurality of nodes are arranged at different parts of the world, and each node maintains a set of same databases. The data is maliciously tampered and difficult to tamper, and the data loss is extremely rare, so that a platform which is fair and transparent and solves the trust crisis is realized.
In the era of the development of the internet of things along with the information technology such as the internet and the like, a sensor, a user, an object and the like are connected together in a new mode, and the information, remote monitoring and management and intelligent network are realized. The current traffic camera is comprehensively installed on a road and used for monitoring the traffic condition of the road, and further, the traffic accident can be restored, the violation of regulations can be inquired, and whether the road is congested or not can be judged according to the data monitored by the camera.
Since the blockchain is a development direction of future technologies, how to combine the blockchain technology with the internet of things and how to link traffic data after combining the blockchain technology with the internet of things further improve user experience, which becomes a challenge of the future technologies.
The above techniques are merely for reference and are not necessarily to be construed as prior art.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to solve the technical problems of how to combine the block chain technology with the Internet of things and how to link the traffic data of the Internet of things.
In order to achieve the above object, in a first aspect, the present invention provides a traffic data uplink method for a block chain based internet of things, including the following steps:
the block chain link point receives traffic data sent by the traffic server, the traffic data is collected by a traffic camera and sent to the traffic server through the Internet of things, and the traffic data comprises: weather conditions, traffic light signals, number of road vehicles and speed of movement of road vehicles;
and carrying out identity verification on the traffic server by the block link point, and if the identity verification passes, carrying out cochain on the traffic data by the block link point after the common identification.
Specifically, the identity verification is to verify the traffic data sent by the traffic server through a public key of the traffic server; the traffic data is data signed with a traffic server private key.
Optionally, the traffic cameras are installed on both sides of the road. The conditions of vehicle traffic and the like on the road are shot through the traffic camera, and the shot information is used as traffic data and sent to the traffic server through the Internet of things. And then the traffic server sends the traffic data to the block chain nodes.
Furthermore, each traffic camera can directly send the detected traffic data to the block chain node through the Internet of things. It can be understood that the connection mode of each traffic camera and the blockchain node is more stable than the connection mode of the traffic server and the blockchain node. Therefore, a mode of transmitting traffic data to the blockchain node through the traffic server may be a preferable scheme.
Specifically, the block link point carries out link up after the traffic data is subjected to the common identification of the practical Byzantine fault-tolerant algorithm PBFT.
It should be noted that the blockchain is a distributed ledger, and may be a private chain, a public chain, or a federation chain.
Specifically, when the block link node receives the traffic data, a transaction including a hash of the traffic data and transaction information thereof can be constructed, and the constructed transaction is broadcasted to the block link network, so that each node stores the transaction in its own block link based on a consensus mechanism, thereby realizing multi-party evidence storage of the traffic data. When the transaction only includes the hash of the traffic data, since the hash of the traffic data is already issued to the blockchain, if the traffic data is tampered, the hash of the tampered traffic data is inconsistent with the hash issued in the blockchain, and therefore, issuing the traffic data to the blockchain is equivalent to storing the traffic data in multiple parties. It should also be noted that when the transaction only includes a hash of the traffic data, the blockchain credit platform typically stores the traffic data in a data repository (non-blockchain), such as RAM, separately.
It should be noted that the transaction described in this specification refers to a piece of data that is created by a user through a client of the blockchain and needs to be finally published to a distributed database of the blockchain. That is, there are narrow and broad categories of transactions in the blockchain. A narrowly defined transaction refers to a transfer of value issued by a user to a blockchain; for example, in a conventional bitcoin blockchain network, the transaction may be a transfer initiated by the user in the blockchain. The broad transaction refers to a piece of business data with business intention, which is issued to the blockchain by a user; for example, an operator may build a federation chain based on actual business requirements, and rely on the federation chain to deploy some other types of online businesses unrelated to value transfer, such as data uplink business, house renting business, vehicle scheduling business, insurance claim settlement business, and the like, in such federation chain, a transaction may be a business message or business request with business intent issued by a user in the federation chain.
Specifically, the block link points receive the traffic data, and can judge whether the road is congested according to the number of road vehicles and the moving speed of the road vehicles in the traffic data. For example: and if the number of the vehicles in the road exceeds a preset vehicle threshold value, or the moving speed of the vehicles exceeding the preset proportion in the road is less than a preset vehicle speed threshold value, judging that the road is congested.
In one possible embodiment, the block link point sends the query result of whether the road is congested to the user based on the determination result of the traffic data according to the query request of the user.
In one possible embodiment, the block link point directly pushes the traffic information of whether the road is congested to the user based on the judgment result of the traffic data.
In one possible embodiment, the block link point uplink the traffic data, which includes the following steps:
if the data volume of the traffic data is larger than the storage threshold value of one block, dividing the traffic data into a plurality of fragment data smaller than the storage threshold value by a block link point;
the block chain node stores a plurality of fragment data into a plurality of blocks of the block chain node respectively.
In one possible embodiment, the block link point uplink the traffic data, which includes the following steps:
if the data volume of the traffic data is larger than the storage threshold value of one block, dividing the traffic data into a plurality of fragment data smaller than the storage threshold value by a block link point;
the block link point stores a first piece of fragment data in the plurality of pieces of fragment data to a current block link point;
and the block chain nodes randomly select other block chain nodes except the current block chain link point in a mode of verifying a random function VRF, and the other block chain link points store the data except the first piece of fragment data in the plurality of pieces of fragment data.
Alternatively, if the traffic server determines that the data size of the traffic data to be sent is too large and is greater than the set data capacity threshold, the hash value of the traffic data may be calculated and sent to the blockchain node for uplink. When a user inquires the traffic data, whether the traffic data stored on the traffic server is real or not can be verified through inquiring the hash value on the link point of the block and the corresponding relation between the hash value and the original traffic data, whether the traffic data is tampered or not is judged, and storage and authenticity supervision of the traffic data based on the traffic server and the block chain are achieved.
In one possible embodiment, the traffic data is structured data, and each attribute of the traffic data is linked, and the attribute of the traffic data includes: geographic location and time.
In one possible embodiment, the method further comprises the steps of:
the block chain node receives digital currency mortised by a traffic server, and allocates corresponding resources for the traffic server, wherein the resources are used for uplink of traffic data sent by the traffic server; the resources include: network resources, CPU resources, and memory resources.
Specifically, in the above scheme, the uplink mode of the traffic data is to obtain the block chain resource used for uplink of the traffic data by mortgage of a certain digital currency, and pay the uplink fee of the traffic data at the block chain node.
It is understood that the allocated blockchain resource may be a CPU, a network resource NET or a RAM. The traffic data is sent to the blockchain node in a mortgage manner, each time the uplink does not send uplink fee independently, but the blockchain resources are consumed, and the mortgage is needed to obtain the blockchain resources so as to pay the uplink fee of the traffic data at the blockchain node.
Optionally, in the above scheme, the uplink mode of the traffic data may be replaced by: the traffic server sends traffic data to the block chain nodes in a transfer mode so that the block chain nodes can execute a cochain process, wherein transfer information sent by the traffic server comprises: from address, to address, traffic data, commission fees. Specifically, the from address is an address of a traffic server, the to address is an address of a blockchain node, and the commission charge is a charge of resources occupied by uplink of the paid traffic data.
Wherein the commission may be digital currency.
It can be understood that after the block link node passes the authentication of the traffic server, the resource fee check is also needed before the uplink of the traffic data. The resource fee means: the resource size and resource fee check of the received traffic data uplink refers to judging whether the resource purchased by the traffic server is larger than the resource fee, if so, the resource fee check is passed, otherwise, the check is not passed.
In a second aspect, the present invention provides a traffic data uplink device of an internet of things based on a block chain, including:
the traffic data receiving unit is used for receiving traffic data sent by the traffic server, the traffic data is collected by a traffic camera and is sent to the traffic server through the Internet of things, and the traffic data comprises: weather conditions, traffic light signals, number of road vehicles and speed of movement of road vehicles;
and the traffic data uplink unit is used for carrying out identity verification on the traffic server, and if the identity verification passes, the block link point carries out uplink after the traffic data is identified together.
