Description

Reliable Internet of Things trading system and method based on trust algorithm trading mechanism

The invention belongs to a reliable internet transaction system and method based on a trust algorithm transaction mechanism, and particularly relates to a transaction system and method for an application in an internet of things service, and each mechanism can automatically operate.

In general, a good IoT service relies on a large amount of data analysis, and the ubiquitous IoT device is capable of providing a large amount of data for data analysis. Therefore, in the case of a full supply and demand situation, the establishment of the Internet of Things data economy is imperative.

And a complete IoT data economy system emphasizes the reliability, intelligence and automation of the transaction process. However, the existing data transaction mechanism cannot meet all the requirements, so it is necessary to design a complete data transaction mechanism to establish a reliable IoT data economy system.

The blockchain (Blockchain) described in the current Internet of Things data economy system is a decentralized and decentralized data computing and preservation platform that is achieved by using the Internet. This principle is the application of the hash function and the decentralized data storage to achieve the content of the control block without specific roles. In addition, for asymmetric symmetry (Asymmetric Cryptography), each party holds a pair of keys, respectively For the private key (public key) and the public key (public key), the message is encrypted by the other party's public key, but can only be decrypted by the other party's private key.

The current state of the art is missing as follows:

1. Lack of transparent data trading methods. In the past, the trading platform was controlled by the operator, and the transaction process and transaction content could not be known by other people. Therefore, when dealing with transaction disputes, there is no good way to deal with them.

2. The data transaction process is not automated enough. IoT data transactions need to handle fast and large transactions, so all actions that take place in the transaction are automated. It is like paying, picking up and handling transaction disputes. RIDES performs the corresponding process and content design for the above actions, enabling the IoT data transaction to be implemented.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventors of the present invention have improved and innovated, and after years of painstaking research, they finally succeeded in researching and developing the reliable IoT trading system and method based on the trust algorithm trading mechanism.

To achieve the above objectives, the data transaction mechanism proposed by the present invention consists of five components: blockchain flow, secure data flow, dispute resolution, intelligent decision making, and information management under the chain. First of all, in order to ensure the reliability of the gold flow, we use the blockchain technology to meet the needs of the transaction records that are open and cannot be tampered with; in order to achieve the security of the data flow, the data will be transmitted through the secure channel established by the secure data flow module; With a specially designed smart contract, the gold stream and data stream will be further integrated to ensure that the buyer can obtain the desired information and sell it. In order to get the expected reward. In addition, this mechanism provides a dispute resolution process to deal with possible transaction disputes. In the smart part, the buyer purchases the most cost-effective data through the value evaluation unit and the trust module based on its own information. The supplier uses the value assessment unit to estimate the target value curve of the transaction and make a reasonable bid to get the highest return. Applying this information economy system to IoT services, the above mechanisms can operate automatically.

A reliable IoT trading system based on a trust algorithm trading mechanism, which mainly comprises an information manager module under the chain, which is used for receiving and transmitting all information of the demander and the supplier, and includes a bulletin board and a zone from the chain. Blockchain; intelligent decision-making module is designed to assist demanders and suppliers to achieve the set goals, and to assist decision-makers and suppliers to automate decision-making; based on blockchain flow module, it deals with all actions related to smart contracts. And a secure data flow module to form a trust-based algorithm trading mechanism; the secure data flow module protects the data transmission through the designed asymmetric encryption, and is based on the trust based on the blockchain gold flow module. The algorithmic trading mechanism; and the dispute handling module are the disputes for all transactions in the chain of information manager modules and smart decision modules, and record the supplier's return records.

The information management module under the chain is for the information manager, the demander and the supplier through the chain to confirm whether the deployed smart contract meets its needs. The smart decision module is based on the contract collector in the system ( Contract Collector), the supplier and the demander, according to their respective needs, through the value evaluation unit and the trust evaluation unit, and then the decision makers choose to trade with the existing object, or deploy the contract themselves, the decision is automated, based on The contract collected by the Contract Collector in the trading system, the supplier and the demander, according to their respective needs, through the value evaluation unit and the trust evaluation unit, and then the smart decision module automatically selects to trade with the existing object, or by itself. Deployment contract.

A reliable IoT transaction method based on the trust algorithm trading mechanism, which mainly includes: an information manager under the chain, through which the information manager, the demander and the supplier can confirm whether the deployed smart contract meets the demand; The smart decision module, according to the contract collected by the contract collector in the system, the supplier and the demander according to their respective needs, through the value evaluation unit and the trust evaluation unit, and then the decision maker chooses to trade with the existing object, or Self-deployment contracts; trust-based algorithmic trading mechanisms; and dispute handling.

The trading mechanism includes smart decision making, transaction information generation, data acquisition, transaction execution, and dispute resolution.

Smart decision-making is for contracts collected according to the contract collector in the system. Suppliers and demanders use the value evaluation unit and the trust evaluation unit according to their respective needs, and then the decision makers choose to trade with existing objects, or It is your own deployment contract.

The transaction information is generated, including the decision of the deployment decision by the smart decision module, the contract constructor will establish a smart contract according to the needs of the contract deployer; and the contract compiler (Contractor) Compiler) and Contractor Deployment, deploy the contract to the blockchain and send the transaction information to the bulletin board.

Data acquisition, including supplier supply information information, and the collected sensing data is encrypted by a random key through an encryption module; the encrypted sensing data is determined to be stored in the cloud or via a data delivery module. It is the local memory; after the storage is completed, the URL of the storage location is transmitted to the contract based on the Blockchain-based Financial Flow Module for contract deployment or editing of the message to the demander.

Transaction execution, including if the demander wants to trade with the supplier, it needs to generate a payment message based on the blockchain gold flow module and transfer it to the contract account for payment; after the supplier confirms that the payment has been successful, the Wrapped Key is generated. And according to the delivery method on the contract, the Wrapped Key is transmitted to the delivery location.

The data application, including the data execution module, decrypts and applies the Wrapped Key from the receiving location; if there is a problem in the transaction process, it will enter the dispute processing module to perform subsequent actions.

Dispute resolution, including the data execution module, believes that there is a problem with the data or key, and will send a dispute message to the pick-up location; if the key is transmitted by the blockchain, it will send the dispute information to the smart contract and monitor the fairness of the smart contract. The third party judges the correctness of the key and the correctness of the data, and records the trial result on the contract. If the supplier does evil, it will be refunded from the contract account to the demander's account; if the non-blockchain transfer key, it must be re-re- Pass the Wrapped Key once.

The invention provides a trust algorithm based transaction mechanism By relying on the Internet of Things trading system and method, when compared with other conventional technologies, it has the following advantages:

1. The transaction process is transparent. Through the smart contracts designed for IoT data transactions, all transaction processes are recorded in the blockchain, and the blockchain is not easy to tamper with, and everyone has a feature to effectively record the transaction process.

2. Establish a process for handling disputes in IoT data transactions, so that the entire transaction process is not handled by humans.

3. A specially designed smart contract can be used to expose the information required for the transaction in the contract, and design the payment mechanism and transaction data through the contract, as well as the processing mechanism after the transaction dispute, so that the entire IoT data transaction process can be completely Human intervention is required.

4. Use the smart contract as the basis for handling transaction disputes, deal with the two types of disputes such as the correctness of the key and the correctness of the data, and record the trial results on the blockchain, and carry out the automatic refund action through the smart contract.
