However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the invention described herein can be implemented in an order other than that illustrated or described herein.

The terminology used in the embodiments of this invention is for descriptive purposes only and is not intended to limit the invention.

[0053] Before providing a further detailed description of the embodiments of the present invention, the nouns and terms involved in the embodiments of the present invention will be explained, and the nouns and terms involved in the embodiments of the present invention shall be interpreted as follows.

[0054] See Figure 1 The IoT platform connects multiple terminal data collection devices and multiple application terminals. The terminal data collection devices collect various physical data, including but not limited to various sensors. The application terminals subscribe to various applications on the IoT platform and query the relevant subscribed data through the IoT platform. In this embodiment of the invention, the data reported by the terminal data collection devices collected by the IoT platform is stored in the form of blockchain.

[0055] like Figure 2 As shown, this embodiment of the invention provides a blockchain-based Internet of Things (IoT) data processing method applied to an IoT platform, including steps S100 to S400.

[0056] S100: Obtain the raw data reported by the device, and save the device information and the raw data to the message queue.

[0057] Specifically, the raw data includes physical data collected by the device acquisition terminal, such as temperature, humidity, or switch signals. The device information includes the model, serial number, network status, communication protocol, and other relevant information of the acquisition terminal. The device acquisition terminal reports the collected raw data to the IoT platform. The IoT platform receives the raw data and saves the device information and the raw data to a message queue.

[0058] S200: Based on the device information of the device, perform time-series parsing on the original data to obtain parsing information, and save the parsing information to the message queue.

[0059] The physical model and device information corresponding to the device acquisition terminal can be stored in the configuration database. Since the control commands or data transmission commands between the device acquisition terminal and the Internet of Things (IoT) communicate according to a communication protocol, different device acquisition terminals may use different communication protocols. Therefore, the specific actual physical data needs to be obtained through parsing. In this embodiment, the IoT platform determines the corresponding physical model from the configuration database based on the device information, performs time-series parsing on the original data based on the physical model to obtain parsed information, and then puts the parsed information back into the message queue.

[0060] S300. The parsed information is encrypted and stored in the blockchain node, and the data credential identifier is obtained.

[0061] Specifically, the IoT platform retrieves the parsed data reported by the terminal devices from the message queue, encrypts the reported data according to the key, stores the reported data to the latest blockchain storage node through the uplink interface, synchronizes it to the blockchain node according to the smart contract, and obtains the returned data credential identifier.

[0062] Optionally, encrypting the parsed information, storing the encrypted parsed information on a blockchain node, and obtaining a data credential identifier specifically includes:

[0063] S310. Obtain the application subscription key information and store the key information;

[0064] S320. Match the key information according to the parsed information, and encrypt the parsed information according to the matched key information;

[0065] S330. Store the encrypted parsed information on the blockchain node and synchronize it to the associated blockchain node;

[0066] S340. Obtain the data credential identifier based on the blockchain synchronization interface.

[0067] Specifically, first, the application subscription key information is obtained from the configuration database, cached in real-time memory, and updated according to the mechanism; then, based on the relevant fields in the reported data, the application key is matched according to the application relevance for data encryption; then, the encrypted reported data is uploaded to the nearest blockchain storage node via a smart contract according to the application terminal and blockchain node configuration database, and synchronized to the associated blockchain node within a preset time, such as 10 seconds; finally, the data credential identifier of the encrypted reported data is obtained from the real-time synchronization interface and saved to the message queue.

[0068] S400. Match the route according to the application subscription, and push the parsed information and the data credential identifier to the application terminal through the route, so that the application terminal can verify the parsed data through the blockchain and the data credential identifier after identity authentication.

[0069] Specifically, the application subscription route is obtained from the configuration database according to the product, and the decrypted data and data credential identifier are packaged and pushed to the URL (uniform resource locator) address of the application terminal in multiple directions. After the application terminal receives the push information, the message data is dumped to the historical database.

[0070] Optionally, the step of matching routes based on application subscriptions and pushing the parsed information and the data credential identifier to the application terminal through the route specifically includes:

[0071] S410. Match routes according to the device information and application subscription of the device, and store the parsed information in real-time memory according to the routes;

[0072] S420. The parsing information and the data credential identifier are pushed to the application terminal through the routing.

[0073] Specifically, firstly, based on the product and application subscription relationship, the optimal route is selected from the push routing rule base to store the reported data in real-time memory; then, based on the route URL dimension, the collected decrypted data and data credential identifier are packaged and pushed to the application terminal receiving URL by message push.

[0074] Implementing this embodiment of the invention has the following beneficial effects: In this embodiment, after the IoT platform obtains the raw data reported by the device, it parses the raw data to obtain parsed information, encrypts the parsed information and stores it in the blockchain node, and obtains a data credential identifier. In addition, the IoT platform matches routes according to application subscriptions and pushes the parsed information and data credential identifier to the application terminal through the route. After receiving the parsed information pushed by the IoT platform, the application terminal obtains the stored parsed information from the blockchain through the data credential identifier, and performs data verification on the parsed information pushed by the IoT platform and the parsed information stored in the blockchain, thereby realizing the credibility verification of the data collected by the terminal device and the data received by the application terminal.

[0075] like Figure 3 As shown, this embodiment of the invention provides a blockchain-based Internet of Things (IoT) data processing system applied to an IoT platform, comprising:

[0076] The first module is used to obtain the raw data reported by the device and save the device information and the raw data to the message queue;

[0077] The second module is used to perform time-series parsing on the original data based on the device information of the device to obtain parsed information, and save the parsed information to the message queue;

[0078] The third module is used to encrypt the parsed information, store the encrypted parsed information on the blockchain node, and obtain the data credential identifier.

[0079] The fourth module is used to match routes according to application subscriptions and push the parsed information and the data credential identifier to the application terminal through the route, so that the application terminal can verify the parsed data through the blockchain and the data credential identifier after identity authentication.

[0081] See Figure 4 This invention provides a blockchain-based Internet of Things (IoT) data processing method, applied to an application terminal, including steps S500 to S700.

[0082] S500 obtains the parsed information and data credential identifier pushed by the IoT platform, and performs identity verification through the IoT verification interface.

[0083] The application terminal retrieves stored application data from the message queue of the IoT platform, and parses the collected data and data credential identifier reported by the device. Based on the on-chain data credential identifier, the application terminal performs identity authentication through the blockchain credential verification interface of the IoT platform, using the application terminal's key and secret. The key and secret information are obtained from the configuration database.

[0084] S600. After successful identity verification, the stored parsing information is obtained from the blockchain node based on the data credential identifier.

[0085] After the application terminal's authentication is successful, it retrieves the parsing information (or decrypted data) stored in the blockchain from the blockchain node based on the data credential identifier.

[0086] Optionally, obtaining the stored parsing information from the blockchain node based on the data credential identifier specifically includes:

[0087] S610. Determine the blockchain node based on the application subscription;

[0088] S620. Obtain the encrypted parsing information from the blockchain node according to the data credential identifier, and decrypt the encrypted parsing information to obtain the stored parsing information.

[0089] Specifically, firstly, the application terminal selects a blockchain node based on the application and blockchain configuration library; then, it obtains the collected data reported by the device terminal from the blockchain node through data credential identification.

[0090] S700 performs data verification on the parsing information pushed by the IoT platform and the stored parsing information.

[0091] Specifically, the application terminal compares the data collected by the device connected to the IoT platform with the data stored on the blockchain to verify whether the data is consistent.

[0092] Implementing this embodiment of the invention has the following beneficial effects: In this embodiment, after the IoT platform obtains the raw data reported by the device, it parses the raw data to obtain parsed information, encrypts the parsed information and stores it in the blockchain node, and obtains a data credential identifier. In addition, the IoT platform matches routes according to application subscriptions and pushes the parsed information and data credential identifier to the application terminal through the route. After receiving the parsed information pushed by the IoT platform, the application terminal obtains the stored parsed information from the blockchain through the data credential identifier, and performs data verification on the parsed information pushed by the IoT platform and the parsed information stored in the blockchain, thereby realizing the credibility verification of the data collected by the terminal device and the data received by the application terminal.

[0096] The seventh module is used to perform data verification on the parsing information pushed by the IoT platform and the parsing information stored therein.
