[0083] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0084] Blockchain is a digital technology for trust transfer, but it doesn't address the question of whether data is trustworthy before it's uploaded to the blockchain. If data is tampered with or corrupted between the time it's collected by IoT sensors and before it's uploaded to the blockchain, even if the data is uploaded to the blockchain for evidence, its trustworthiness cannot be guaranteed.

[0085] In related technologies, IoT devices are often unable to run the full software functions of blockchain nodes due to resource limitations. Resource limitations include:

[0086] (1) Computing resources are insufficient to support the overhead of the blockchain protocol stack;

[0087] (2) Storage resources are insufficient to store the blockchain ledger, or even the block headers used for simple payment verification;

[0088] (3) Network resources are insufficient to support the inter-node transmission required by the blockchain consensus mechanism.

[0089] Therefore, in traditional IoT chain-linking solutions, IoT devices are used as a means of data collection. Although the collected data (possibly through devices such as IoT gateways) is eventually uploaded to the blockchain; however, since IoT devices cannot run the blockchain node protocol stack, traditional IoT chain-linking solutions cannot achieve data credibility that matches or is close to that of the blockchain technology itself.

[0090] To this end, a one-way trust enhancement solution is proposed, that is, the trustworthiness of IoT devices is enhanced towards the blockchain. Specifically:

[0091] (1) IoT device side: The collected data is signed and processed, and then submitted to the blockchain for evidence storage.

[0092] (2) Blockchain side: The blockchain system, or the blockchain system helps the application system to perform operations such as signature verification on the data submitted by the Internet of Things in order to confirm the credibility of the data collected by the Internet of Things.

[0093] However, in related technologies, one-way trust enhancement solutions impose fixed trustworthiness requirements for IoT data on-chain, or, within the same application system, impose the same trustworthiness requirements on all IoT devices on-chain. Due to varying needs in different scenarios, the most comprehensive trustworthiness requirements are not necessarily required. Otherwise, establishing uniform trustworthiness requirements for all IoT devices would introduce significant limitations and waste resources for certain IoT devices. For example, imposing excessively high trustworthiness requirements on IoT devices in certain scenarios would consume additional computing and storage resources, leading to increased resource consumption and costs.

[0094] The requirements for different scenarios can be found in Table 1.

[0095] Table 1

[0096] To address the above-mentioned issues, a method, device, equipment, and system for uploading IoT data to a blockchain are provided. The method and device are based on the same patent application concept. Since the principles of the method and device are similar, the implementation of the device and method can refer to each other, and any repetitions will not be repeated.

[0097] As shown in Figure 1, the present disclosure provides a method for uploading IoT data to a blockchain. The method is applied to a blockchain node, that is, the method is executed by the blockchain node. The method includes:

[0098] Step 101: receiving first data and credibility verification information submitted by an IoT device, where the credibility verification information is generated by the IoT device based on its own credibility requirements;

[0099] The first data is the raw data collected by the IoT device. It should be noted that due to the varying needs of different scenarios, the corresponding trustworthiness requirements for IoT devices in different scenarios vary. For IoT devices, since trustworthiness verification information is generated based on their own trustworthiness requirements, this can not only ensure data trustworthiness, but also conserve IoT device resources and reduce IoT device costs.

[0100] Step 102: Performing credibility verification on the first data and the credibility verification information using a credibility verification scheme, wherein the credibility verification scheme matches the credibility requirement corresponding to the IoT device;

[0101] If the credibility verification information is generated by the IoT device using a symmetric key to encrypt the first data, the blockchain node uses the first data and the credibility verification information as input parameters for verification. Specifically, the blockchain node encrypts the first data using the symmetric key and compares the encrypted data with the credibility verification information. If they match, step 103 is executed; otherwise, the first data is discarded.

[0102] If the credibility verification information is generated by the IoT device using the private key in the asymmetric key to encrypt the first data, the blockchain node uses the first data and the credibility verification information as input parameters for verification. Specifically, the blockchain node decrypts the credibility verification information using the public key in the asymmetric key and compares the decrypted data with the first data. If they are identical, step 103 is executed; otherwise, the first data is discarded.

[0103] Step 103: If the credibility verification passes, the first data is saved on the blockchain.

[0104] In an optional embodiment, the first data is stored in a preset shared database, wherein each blockchain node on the blockchain can obtain data from the shared database, thereby enabling synchronization of the first data among blockchain nodes.

[0105] In an optional embodiment, saving the first data on a blockchain specifically includes:

[0106] Using a smart contract to write the first data into the blockchain ledger;

[0107] The consensus mechanism is used to synchronize blockchain ledgers between blockchain nodes.

[0108] This embodiment can fully utilize the functions of the blockchain, thereby achieving the purpose of saving resources and equipment costs.

[0109] In some embodiments, before step 102, the method of the present disclosure further includes:

[0110] Obtaining a device identifier of the IoT device;

[0111] According to the device identification and the correspondence between the IoT device and the credibility requirement, a credibility verification scheme that matches the credibility requirement corresponding to the IoT device is determined.

[0112] That is, the blockchain node pre-establishes a correspondence between IoT devices and credibility requirements. Optionally, the correspondence between IoT devices and credibility requirements includes one of the following:

[0113] The correspondence between the device identification of the IoT device, the scenario identification of the scenario in which the IoT device is located, and the trustworthiness requirements;

[0114] The correspondence between the device identifier, the scenario identifier, and the credibility verification scheme;

[0115] The correspondence between the device identifier, the scenario identifier, the credibility requirement, and the credibility verification scheme;

[0116] The correspondence between the device identification and the credibility requirement;

[0117] The correspondence between the device identification and the credibility verification scheme;

[0118] The correspondence between the device identification, the credibility requirement, and the credibility verification scheme.

[0119] In this way, the correspondence between the IoT device and the credibility requirement is queried through the device identification, the credibility requirement corresponding to the IoT device is determined, and a credibility verification scheme matching the credibility requirement is determined based on the credibility requirement.

[0120] Then, the blockchain node establishes a correspondence between the IoT device and the credibility requirement based on the IoT device. In some embodiments, the method of the present disclosure further includes:

[0121] 1) receiving first information sent by the IoT device;

[0122] The first information includes one or more of the following:

[0123] Device identification of IoT devices;

[0124] The scene identifier of the scene where the IoT device is located;

[0125] Credibility requirements;

[0126] Trustworthiness requires verification schemes.

[0127] In an optional embodiment, receiving the first information sent by the IoT device includes:

[0128] Receive a registration request sent by the Internet of Things device, where the registration request includes the first information.

[0129] 2) establishing a correspondence between IoT devices and credibility requirements based on the first information;

[0130] Optionally, the correspondence between the IoT device and the credibility requirement includes one of the following:

[0131] The correspondence between the device identification of the IoT device, the scenario identification of the scenario in which the IoT device is located, and the trustworthiness requirements;

[0132] The correspondence between the device identifier, the scenario identifier, and the credibility verification scheme;

[0133] The correspondence between the device identifier, the scenario identifier, the credibility requirement, and the credibility verification scheme;

[0134] The correspondence between the device identification and the credibility requirement;

[0135] The correspondence between the device identification and the credibility verification scheme;

[0136] The correspondence between the device identification, the credibility requirement, and the credibility verification scheme.

[0137] 3) Save the correspondence between IoT devices and credibility requirements on the blockchain.

[0138] In an optional embodiment, the correspondence between IoT devices and trustworthiness requirements is stored on a blockchain, including:

[0139] Using smart contracts, the correspondence between the IoT devices and the credibility requirements is written into the blockchain ledger;

[0140] The blockchain ledger is synchronized between blockchain nodes using a consensus mechanism.

[0141] This embodiment can fully utilize the functions of the blockchain, thereby achieving the goal of saving resources and equipment costs. It should be noted that when a blockchain node needs to determine a credibility verification scheme, it can use a smart contract to query the blockchain ledger for the correspondence between IoT devices and credibility requirements, thereby determining the credibility requirements corresponding to the IoT device and determining a matching credibility verification scheme based on the credibility requirements.

[0142] This disclosure does not limit the scheme of the correspondence between IoT devices and credibility requirements. Only the following examples are given:

[0143] Device Identifier (ID) – Scenario ID – Credibility Requirements

[0144] Among them, the device ID and scene ID are N:1 mappings, and the scene ID and credibility requirement are 1:1 mappings.

[0145] For example: Smart Thermometer 001 - Comfort Air Conditioning Outlet Room Temperature Monitoring - Trust Level 1 (requires that the submitted data be trustworthy, and allows data loss, duplication, and disorder).

[0146] For example: Smart Belt Scale A - Fuel Usage Monitoring - Trust Level 2 (requires that the submitted data be trustworthy, and does not allow data loss or duplication).

[0147] This mapping method uses scenario IDs to categorize trustworthiness requirements and IoT devices, making maintenance and management easier.

[0148] For example, when a new IoT device needs to be replaced in a certain scenario, it is only necessary to establish a corresponding relationship between (device ID, scenario ID).

[0149] For another example, when the credibility requirement of a certain scenario changes, only one set of correspondences (scenario ID, credibility requirement) needs to be changed, without changing multiple correspondences of N (device ID, scenario ID).

[0150] The method for uploading IoT data to a blockchain in the disclosed embodiment receives first data and credibility verification information submitted by an IoT device, wherein the credibility verification information is generated by the IoT device based on its own credibility requirements; a credibility verification scheme is used to perform credibility verification on the first data and the credibility verification information, wherein the credibility verification scheme matches the credibility requirements corresponding to the IoT device; if the credibility verification passes, the first data is saved on the blockchain. In this way, for the IoT device side, since the credibility verification information is generated based on its own credibility requirements, while ensuring data credibility, IoT device resources can be saved and IoT device costs can be reduced; the blockchain node side performs credibility verification on the first data and the credibility verification information based on the credibility verification scheme that matches the credibility requirements corresponding to the IoT device, thereby realizing the uploading of IoT data to the blockchain.

[0151] The present disclosure also provides a method for uploading IoT data to a blockchain, which is applied to an IoT device, i.e., the method is executed by the IoT device. The method includes:

[0152] Generate credibility verification information corresponding to the first data according to its own credibility requirements;

[0153] Submitting the first data and the credibility verification information to a blockchain node, where the first data and the credibility verification information are used by the blockchain node to perform credibility verification; wherein the credibility verification scheme adopted by the blockchain node for credibility verification matches the credibility requirements corresponding to the Internet of Things device.

[0154] Optionally, before generating the credibility verification information corresponding to the first data according to the credibility requirement required by the method, the method further includes:

[0155] Acquire first data or generate first data.

[0156] Optionally, obtaining the first data or generating the first data may refer to collecting the first data or generating the first data.

[0157] As shown in FIG2 , the embodiment of the present disclosure further provides a method for uploading IoT data to a blockchain, which is applied to an IoT device, i.e., the method is executed by the IoT device. The method includes:

[0158] Step 201, collecting first data;

[0159] Step 202: Generate credibility verification information corresponding to the first data according to the credibility requirements required by the device;

[0160] Optionally, according to the credibility requirements required by itself, data security processing is performed on the first data to obtain credibility verification information corresponding to the first data.

[0161] It should be understood that different credibility requirements require different data security processing methods. The following examples are as follows:

[0162] Example 1: Trust Level 1

[0163] Feasibility requirements: The submitted data must be credible, and data loss, duplication, and disorder are allowed.

[0164] VER=SIGN(HASH(SampleData))

[0165] Among them, VER: credibility verification information; SIGN: signature algorithm; HASH: hash algorithm; SampleData: sampled original data.

[0166] Example 2: Trust Level 2

[0167] Feasibility requirements: The submitted data must be credible, and data loss, duplication, and disorder are not allowed.

[0168] VER i =SIGN-1(HASH-1(SampleData i ,DataHis i-1 ))

[0169] And DataHis i =SIGN-2(HASH-2(SampleData i ,DataHis i-1 )),as well as

[0170] DataHis0=DH0

[0171] Among them: VER i: Credibility verification information of the i-th collected and reported data; SIGN-1, SIGN-2: both are signature algorithms; HASH-1, HASH-2: both are hash algorithms; SampleData i : The original data collected for the i-th time; DataHis i : After the i-th collection, calculate the verification information of the collection history; DH0: the initial value of DataHis.

[0172] Step 203: Submit the first data and the credibility verification information to the blockchain node, where the first data and the credibility verification information are used by the blockchain node to perform credibility verification; wherein the credibility verification scheme adopted by the blockchain node for credibility verification matches the credibility requirements corresponding to the IoT device.

[0173] Here, the blockchain node side performs credibility verification on the first data and the credibility verification information based on a credibility verification scheme that matches the credibility requirements corresponding to the IoT device, thereby realizing the uploading of the IoT data to the chain.

[0174] The method for uploading IoT data to a blockchain in an embodiment of the present disclosure collects first data; generates credibility verification information corresponding to the first data based on its own credibility requirements; submits the first data and the credibility verification information to a blockchain node, and the first data and the credibility verification information are used by the blockchain node to perform credibility verification; wherein the credibility verification scheme adopted by the blockchain node for credibility verification matches the credibility requirements corresponding to the IoT device. In this way, since the credibility verification information is generated based on its own credibility requirements, while ensuring the credibility of the data, it can also save IoT device resources and reduce IoT device costs.

[0175] In some embodiments, the method of the present disclosure further comprises:

[0176] Sending first information to the blockchain node, where the first information is used by the blockchain node to establish a correspondence between the IoT device and the credibility requirement; wherein the first information includes one or more of the following:

[0177] Device identification of IoT devices;

[0178] The scene identifier of the scene where the IoT device is located;

[0179] Credibility requirements;

[0180] Trustworthiness requires verification schemes.

[0181] In an optional embodiment, the sending the first information to the blockchain node includes:

[0182] Send a registration request to the blockchain node, where the registration request includes the first information.

[0183] That is to say, through the registration process between the IoT device and the blockchain node, the relevant information of the IoT device (first information), mainly the credibility requirements or credibility requirement verification scheme corresponding to the IoT device, is reported to the blockchain node, so that the blockchain node can establish a correspondence between the IoT device and the credibility requirements.

[0184] Optionally, the correspondence between the IoT device and the credibility requirement includes one of the following:

[0185] The correspondence between the device identification of the IoT device, the scenario identification of the scenario in which the IoT device is located, and the trustworthiness requirements;

[0186] The correspondence between the device identifier, the scenario identifier, and the credibility verification scheme;

[0187] The correspondence between the device identifier, the scenario identifier, the credibility requirement, and the credibility verification scheme;

[0188] The correspondence between the device identification and the credibility requirement;

[0189] The correspondence between the device identification and the credibility verification scheme;

[0190] The correspondence between the device identification, the credibility requirement, and the credibility verification scheme.

[0191] In some embodiments, before executing step 203, the method of the embodiment of the present disclosure may further include:

[0192] A trustworthy verification scheme is required to register IoT devices with blockchain nodes. This is done to cope with changes in IoT device scenarios or when IoT devices are re-registered, so that blockchain nodes can verify the data submitted by IoT devices in a timely and accurate manner.

[0193] Referring to Figure 3, the following describes the registration process between IoT device 1 and a blockchain node. The registration process between IoT device 2 and a blockchain node is the same and can be simply referred to in Figure 3.

[0194] Step 0: IoT device 1 prepares to enable the device and determines the required trustworthiness requirements;

[0195] Step 1: IoT device 1 initiates a registration request to blockchain node 2. The registration request includes device identification, scenario identification, credibility requirements, etc.

[0196] Step 2: After receiving the registration request, blockchain node 2 establishes a corresponding relationship between the IoT device and the credibility requirement.

[0197] Step 3: Use the consensus mechanism to synchronize the correspondence between IoT devices and trustworthiness requirements on the chain.

[0198] Here, blockchain node 2 is provided with an IoT device registration module, and blockchain node 1 and blockchain node 4 are provided with a receiving verification module.

[0199] It should be noted that to share the load of blockchain nodes, each functional module can be located on different blockchain nodes, or it can be located on the same blockchain node. Even if each functional module is located on different blockchain nodes, the data on the blockchain is shared synchronously through the consensus mechanism.

[0200] Referring to Figure 4 , the following describes the data collection and upload process for IoT device 1. The process for IoT device 2 is the same and can be simply referred to in Figure 4 , which will not be further illustrated.

[0201] Step 1: IoT device 1 collects raw data;

[0202] Step 2: IoT device 1 performs data security processing on the original data based on its own credibility requirements and generates credibility verification information;

[0203] Step 3: IoT device 1 submits the original data and credibility verification information to blockchain node 1;

[0204] Step 4: Blockchain node 1 determines a credibility verification scheme based on the device ID of IoT device 1.

[0205] Here, blockchain node 1 determines the corresponding credibility verification scheme based on the device ID of IoT device 1 by querying the correspondence between IoT devices and credibility requirements.
