Description
Technical Field
The invention relates to the technical crossing field of the Internet of things and a block chain, in particular to a method and a system for uplink of weather data of the Internet of things on the 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 monitoring of the weather data of the Internet of things is more and more convenient for the life of people, and users can arrange clothing and travel by inquiring the weather data published by various weather detection mechanisms.
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 the weather data after combining the blockchain technology with the internet of things, so as to improve user experience, becomes a technical challenge.
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 weather data of the Internet of things.
In order to achieve the above object, in a first aspect, the present invention provides a method for uplink of weather data of an internet of things on a blockchain, including the following steps:
the block chain node receives weather data sent by a weather server, the weather data is collected by a weather detector and sent to the weather server through the Internet of things, and the weather data comprises: geographic location, temperature, wind direction, wind power, humidity, and air quality;
and carrying out identity verification on the weather server by the block link point, and if the identity verification passes, carrying out cochain on the weather data by the block link point after the common identification.
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 chain node receives the weather data, a transaction including hash of the weather data and transaction information thereof can be constructed, and the constructed transaction is broadcasted to the block chain network, so that each node stores the transaction in the block chain thereof based on a consensus mechanism, and thus, multi-party evidence storage of the weather data is realized. When the transaction only includes the hash of the weather data, since the hash of the weather data is already issued to the blockchain, if the weather data is tampered, the hash of the tampered weather data is inconsistent with the hash issued in the blockchain, and therefore, issuing the weather data to the blockchain is equivalent to storing the weather data by multiple parties. It should also be noted that when the transaction only includes a hash of the weather data, the blockchain attestation platform typically stores the weather data in a separate data store (non-blockchain), such as RAM.
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 identity verification is to verify weather data sent by the weather server through a public key of the weather server; the weather data is data signed with a weather server private key.
Optionally, the weather detector is mounted at the detected geographic location, the weather detector comprising: temperature detectors, wind direction and wind force detectors, humidity detectors, and air quality detectors. The temperature sensor detects temperature, the wind direction and wind power detector detects wind direction and wind power, the humidity detector detects air humidity, and the air quality detector detects air quality.
It can be understood that the weather data are detected by the weather detector, sent to the weather server through the internet of things and then sent to the blockchain node by the weather server.
Further, each weather detector can directly send detected weather data to the blockchain node through the internet of things. It can be appreciated that the connection of the weather server to the blockchain node is more stable than the connection of the weather detectors to the blockchain node. Therefore, a mode of sending the weather data to the blockchain node through the weather server can be taken as a preferable scheme.
Specifically, the block link point carries out chaining after a practical Byzantine fault-tolerant algorithm PBFT consensus on the weather data.
In a possible embodiment, the block nodes receive the weather data, and may send the weather data to the user according to a weather inquiry request of the user, or directly send the weather data of the corresponding geographical location to the user when monitoring that the user is at the corresponding geographical location.
In one possible embodiment, the block link point uplink the weather data, which includes the following steps:
if the data volume of the weather data is larger than the storage threshold value of one block, dividing the weather data into a plurality of fragment data smaller than the storage threshold value by a block chain node;
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 weather data, which includes the following steps:
if the data volume of the weather data is larger than the storage threshold value of one block, dividing the weather data into a plurality of fragment data smaller than the storage threshold value by a block chain node;
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.
Optionally, if the weather server determines that the data size of the weather data to be sent is too large and is greater than the set data capacity threshold, the hash value of the weather data may be calculated, and the hash value is sent to the block chain node for uplink. When a user inquires the weather data, whether the weather data stored on the weather 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 weather data, whether the weather data is tampered or not is judged, and storage and authenticity supervision of the weather data based on the weather server and the block chain are achieved.
In a possible embodiment, the weather data is structured data, and each attribute of the weather data is linked, where the attribute of the weather data includes: and collecting data time.
In one possible embodiment, the method further comprises the steps of:
the block link node receives digital currency mortgaged by a weather server, and allocates corresponding resources for the weather server, wherein the resources are used for uplink of weather data sent by the weather server; the resources include: network resources, CPU resources, and memory resources.
Specifically, in the above scheme, the uplink mode of the weather data is to obtain the block chain resource used for uplink of the weather data by mortgage of certain digital currency, and pay the uplink fee of the weather data at the block chain link point.
It is understood that the allocated blockchain resource may be a CPU, a network resource NET or a RAM. The weather data is sent to the blockchain node in a mortgage mode, each time the uplink does not send uplink fee independently, but block chain resources are consumed, and the mortgage is needed to obtain the block chain resources so as to pay the uplink fee of the weather data at the blockchain node.
Optionally, in the above scheme, the uplink mode of the weather data may be replaced by: the weather server sends weather data to the block chain node in a transfer mode so that the block chain node can execute a cochain process, wherein the transfer information sent by the weather server comprises: from address, to address, weather data, commission fees. Specifically, the from address is an address of a weather server, the to address is an address of a blockchain node, and the commission is a cost of resources occupied by uplink of the paid weather data.
Wherein the commission may be digital currency.
It can be understood that, after the identity of the weather server is verified by the block link node, the resource fee check is also required before uplink is performed on the weather data. The resource fee means: and the resource size required by the uplink of the received weather data, wherein the resource fee check refers to judging whether the resource purchased by the weather 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 an uplink system of weather data of the internet of things on a blockchain, including:
the weather data receiving unit is used for receiving weather data sent by the weather server, the weather data is collected by the weather detector and is sent to the weather server through the Internet of things, and the weather data comprises: geographic location, temperature, wind direction, wind power, humidity, and air quality;
