In IOT related technology, object data acquisition is one of the important links. In some embodiments, it may be desirable to enable trusted device data collection to secure data, e.g., collecting device data and writing it to a blockchain for trusted preservation, trusted processing. In some scenarios, the device to collect device data does not itself have a network connection function, such as electric bicycles, garbage collection devices, sewage treatment devices, and the like. For this type of device, if device data acquisition is to be implemented, proprietary hardware (e.g., proprietary hardware including control chips, network modules) may be provided on the device in some embodiments, through which acquisition of device data and networking of the acquired device data to a data service platform for storage into a blockchain by the data service platform for storage or further processing. However, setting the proprietary hardware on the device requires increasing costs associated with production, installation, etc. of the proprietary hardware, and the application range of the proprietary hardware is limited, and the adaptation degree with various devices may not be high.

Fig. 1-1 is a schematic diagram of an application scenario of a bluetooth-based data acquisition system according to some embodiments of the present disclosure.

The bluetooth-based data acquisition system provided by some embodiments of the present disclosure may be applicable to various application scenarios in which device data is acquired by a device and transmitted to a data service platform, so that the data service platform may perform trusted storage or further processing of the device data.

As shown in fig. 1-1, a target device 110 and a data service platform 140 may be included in an application scenario 100 of a bluetooth-based data acquisition system.

The target device 110 may be any device that needs to collect device data, such as an electric bicycle, a garbage collection device, a sewage treatment device, etc. The target device 110 itself may not have networking communication capabilities.

Data services platform 140 may be a services platform (which may be referred to as an IOT platform) that is deployed on a processing device (e.g., various processing devices such as a computer, cloud platform, etc.). The data service platform 140 may be used as a service platform for interfacing with a blockchain for providing a store blockchain processing service for data, and the data service platform 140 may also provide data processing functions to enable further processing of the collected device data.

A blockchain may be made up of a plurality of blockchain link points. In some embodiments, the blockchain node may be a variety of computing devices, such as a laptop computer, a desktop computer, a server, and the like. More generally, in a blockchain, a blockchain node may receive a transaction uploaded (or broadcast) to the chain, invoke a corresponding smart contract to complete execution of the transaction, and write the transaction and the results of the transaction execution into blockchain data. In some embodiments, the data service platform 140 may initiate a data logging transaction request to the blockchain network to write data into the blockchain for storage.

The consensus mechanism is a necessary component for the normal operation of the blockchain network and is used for ensuring that the blockchain data stored by each node is kept consistent. Multiple nodes may agree on operations to receive (input of corresponding code), generate (output of corresponding code or intermediate result) data and/or perform by running a consensus protocol, and nodes participating in the consensus may be referred to as consensus nodes. For example, for a plurality of transactions involving a new block, each consensus node may agree on the order of execution of the plurality of transactions by running a consensus protocol.

Blockchain data (also referred to as on-chain data) may include blockchain data and state data (also referred to as global state or world state) that are commonly known, and the writing of blockchain data is also referred to as the uplink. The block data comprises blocks which are continuously generated and are linked in time sequence, and each consensus node can uplink the new block by running a consensus protocol. Consensus passing means that each consensus node can write the same new block to the blockchain data. For example only, in some embodiments, the condition for consensus passing includes consensus nodes exceeding a preset ratio (e.g., 2/3) agreeing to uplink the new block. The status data may include status variables associated with each account, such as a balance of an individual, organization controlled external account, and, for example, a contract status of a contract account.

In some embodiments, as shown in fig. 1-2, based on the application scenario 100 (including the target device 110 and the data service platform 140), the bluetooth-based data acquisition system according to some embodiments of the present disclosure may further include a bluetooth module 120 and a terminal 130.

In some embodiments, a bluetooth module 120 connected to the target device 110 may be installed on the target device 110.

The bluetooth module 120 may employ various types of bluetooth modules according to the need.

In some embodiments, the Bluetooth module 120 may be connected to a control chip or other device component of the target device 110 that may generate device data via a connection so that the Bluetooth module 120 may obtain the device data of the target device 110 via the connection.

The details of the identity registration related process procedure of the bluetooth module 120 may be referred to fig. 3 and the related description thereof, and the details of the device data trusted acquisition related process procedure of the target device 110 may be referred to fig. 2 and the related description thereof.

In some embodiments, bluetooth module 120 may also include a trusted execution environment in which the aforementioned business applications may be placed for execution. The trusted execution environment (Trusted Execution Environment, TEE) is a secure area on the processor of the device that ensures the security, confidentiality and integrity of code and data loaded into the environment, thereby ensuring the trustworthiness of the results obtained after execution of the code program in the module/device with the trusted execution environment. Exemplary trusted execution environments may include trusted execution environments based on Software Guard Extensions (SGX), secure Encrypted Virtualization, or trust zone technologies, among others. Taking SGX as an example, when a program is executed in a trusted execution environment, the program is protected by enclaspe, and the outside world cannot tamper with data located in the enclaspe or affect the execution process of the program.

The terminal 130 may include one or more terminals, and may be various types of terminals, for example, mobile terminals such as a mobile phone, and may also be a Gateway (Gateway), and the like. The terminal 130 may have a bluetooth communication function and a networking communication function. In some embodiments, terminal 130 may include components such as bluetooth modules, network modules (which may be used to implement networking communications), processors, memory units, and the like. In some embodiments, terminal 130 may also include a trusted execution environment similar to bluetooth module 120 described previously. The terminal 130 may be provided here by way of example only, and may be other processing devices having similar functionality.

In some embodiments, bluetooth module 120 may perform bluetooth communication with terminal 130 (e.g., terminal 130 may search for a bluetooth module via bluetooth functionality and may establish bluetooth communication with a bluetooth module via bluetooth pairing), and terminal 130 may interact with data service platform 140 via networking, such that bluetooth module 120, terminal 130, data service platform 140 may participate in implementing an identity registration-related process of bluetooth module 120, a device data trusted acquisition-related process of target device 110. The details of the identity registration related process procedure of the bluetooth module 120 may be referred to fig. 3 and the related description thereof, and the details of the device data trusted acquisition related process procedure of the target device 110 may be referred to fig. 2 and the related description thereof.

Fig. 2 is an exemplary interaction flow diagram of a bluetooth-based data collection method according to some embodiments of the present description.

As shown in fig. 2, an interaction flow of a bluetooth module (e.g., bluetooth module 120), a processing device (e.g., terminal 130), and a data service platform (e.g., data service platform 140) is shown.

In some embodiments, the processing device may be a device or system for bluetooth communication with a bluetooth module and interaction with a data server, and the processing device may have bluetooth communication functions and networking communication functions. The processing device may comprise a processing device or a system of processing devices. By way of example, the processing device may be various types of terminals (e.g., cell phones, tablets, gateways, etc.), computing devices (e.g., laptop computers, desktop computers, servers, etc.), and the like. In some embodiments, the processing device may include components such as bluetooth modules, network modules (which may be used to implement networking communications), processors, memory units, and the like. The bluetooth module may perform bluetooth communication with the processing device, and the processing device may interact with the data service platform in a networking manner, so that the bluetooth module, the processing device, and the data service platform may participate in a relevant processing procedure for implementing the bluetooth-based data acquisition method in some embodiments of the present disclosure, so that trusted device data acquisition of the target device 110 may be implemented.

For convenience of explanation, the steps in the flowchart 200 of the present specification are mainly described by taking bluetooth module execution (e.g., steps 210, 220, 230) and processing device execution (e.g., step 240) as examples.

The bluetooth-based data acquisition method 200 may include:

step 210, obtaining device data of a target device.

In some embodiments, step 210 may be performed by a device data acquisition module.

The device data of the target device may include various data related to the target device. Taking an electric bicycle available for lease as an example, the device data may include a device identifier (for example, identifier information indicating a device identity such as a device ID) of the electric bicycle, a timestamp of the data, a single mileage of the lease, a total mileage of the lease, an electric quantity, an electric current, a voltage, a battery state of charge (SOC) and a battery state of health (SOH) of the electric bicycle.

In some embodiments, the bluetooth module may obtain various device data of the target device based on the data acquisition request, and as an example, the processing device may send the data acquisition request to the bluetooth module by performing bluetooth communication with the bluetooth module, and the bluetooth module may obtain various device data of the target device based on the data acquisition request. In some embodiments, the bluetooth module may also periodically acquire or otherwise automatically acquire various device data of the target device at a preset acquisition period.

In some embodiments, the bluetooth module may further obtain a data model, where the data model may include data content to be obtained, for example, may include a type of data to be obtained (such as a device identifier, a timestamp, a single mileage rented, a total mileage rented, etc.), and may further include a data format specification of various data, such as a data value type, a data value range, etc. In some embodiments, the data model may be agreed upon by the data services platform and pre-saved to the bluetooth module. In some embodiments, the data model may also be sent by the data service platform to the processing device and sent by the processing device to the bluetooth module via bluetooth communication.

In some embodiments, the bluetooth module may obtain device data of the target device based on the data model, such that one or more data specified in the data model may be obtained (in some embodiments, data values of the one or more data may also conform to the data format specification specified in the data model).

In some embodiments, after the bluetooth module obtains the device data, data inspection, cleaning, arrangement, combination, and other data arrangement may be performed on the device data.

And 220, performing trusted processing on the device data based on the Bluetooth module private key to obtain trusted device data.

In some embodiments, step 220 may be performed by a trusted processing module.

For the information security protection of the device data, the bluetooth module may correspond to a public key (referred to as a bluetooth module public key) and a private key (referred to as a bluetooth module private key). The public key of the Bluetooth module and the private key of the Bluetooth module are a key pair, the public key of the Bluetooth module can be issued outwards, for example, the public key of the Bluetooth module is held by a data service platform, and the private key of the Bluetooth module is held by the Bluetooth module. The public and private keys of the bluetooth module may be generated by the bluetooth module, for example, by a key pair generation algorithm in a service application embedded in the bluetooth module.

The trusted processing refers to processing for protecting the data by information security technology, and the trusted processing can enable the data to have trusted properties, wherein the trusted properties can comprise tamper resistance of the data, authenticity of the data can be guaranteed, and the like. The information security technology may refer to information technology that may implement data tamper resistance or authenticity verification, such as encryption, signing, processing in trusted units, and store blockchain tamper resistance.

The data obtained after the trusted processing of the device data is referred to as trusted device data.

In some embodiments, the bluetooth module performing trusted processing of device data based on the bluetooth module private key may include: and signing the device data based on the Bluetooth module private key. For example, the bluetooth module may generate a digest of the device data based on a digest algorithm and encrypt the digest with a bluetooth module private key to generate a digital signature, thereby protecting the security of the device data by signing. In some embodiments, trusted processing of device data by the bluetooth module may also include other processes that may secure device data.

In some embodiments, in order to protect the bluetooth module private key by using the information security technology, the bluetooth module may store the bluetooth module private key by using a secure storage method, and further may perform trusted processing on the device data based on the bluetooth module private key stored by using the secure storage method.

The secure storage method of the bluetooth module private key may include various storage methods capable of performing information security protection on the bluetooth module private key to avoid disclosure, for example, the secure storage method may be used to store the bluetooth module private key after confusion processing, may also be used to store the bluetooth module private key by other white-box encryption methods, and may also be used to store the bluetooth module private key by secure storage methods such as files, software systems, etc.

The confusion processing performed on the private key may be processing that can make the private key obscure in the memory (for example, processing that stores the private key as hexadecimal characters or replaces characters in a key string, etc.), when the private key is stored after the confusion processing, when the bluetooth module signs or decrypts by using the private key, the corresponding anti-confusion processing is performed on the private key before performing the cryptographic operation.

White-box encryption refers to an encryption method capable of resisting white-box attacks, and can be realized through various existing cryptographic algorithms capable of realizing white-box encryption.

When the private key is stored in a file form, the security of the private key is usually protected by a password, for example, the file storing the private key is encrypted by the password, and when the private key is used for signing or decrypting, the private key file needs to be read into a memory or a cryptographic module for cryptographic operation. When the secret key is stored in a software system mode, the security of the storage and access of the secret key is managed by the software system, and the storage form and the security of the secret key can be different under different software systems.

And 230, transmitting the trusted device data and the blockchain uplink identifier of the Bluetooth module to the processing device through Bluetooth communication with the processing device.

In some embodiments, step 230 may be performed by a data output module.

In order to realize the trusted device data obtained by the Bluetooth module is trusted on the blockchain, the Bluetooth module can be provided with a corresponding blockchain uplink identifier, the blockchain uplink identifier can be used for indicating that the identity of the corresponding Bluetooth module is authenticated, and the data transmitted by the Bluetooth module can be written into the blockchain for storage. The blockchain uplink identification may be determined by the data service platform and sent to the bluetooth module via the processing device for acquisition by the bluetooth module. For more details on the bluetooth module acquiring blockchain uplink identification see fig. 3 and its associated description.

The Bluetooth module can send the acquired trusted device data and the blockchain uplink identifier of the Bluetooth module to the processing device through Bluetooth communication with the processing device, so that the processing device can provide the trusted device data and the blockchain uplink identifier for the data service platform to realize the processing of the trusted device data in the blockchain.

Step 240, by interacting with the data service platform: providing the trusted device data and the blockchain uplink identifier so that the data service platform can perform blockchain storage processing of the trusted device data.

In some embodiments, step 240 may be performed by a service platform interaction module.

In some embodiments, the processing device may interact with the data service platform in a networked manner, the processing device may send the obtained trusted device data and blockchain uplink identification to the data service platform, and the data service platform may perform the store blockchain processing of the trusted device data.

In some embodiments, the store blockchain processing by the data service platform may include: and performing data verification, and performing whether to store the trusted device data into the blockchain based on the result of the data verification. For example, if the data check passes, the trusted device data may be stored in the blockchain, and if the data check fails, the trusted device data may not be stored in the blockchain.

In some embodiments, the data verification may include a trusted verification of trusted device data based on the bluetooth module public key, the trusted verification referred to as a first trusted verification. In some embodiments, as previously described, the trusted device data may be signed based on a bluetooth module private key, and the first trusted verification may include: acquiring a digital signature of the trusted device data; the digital signature is verified based on the bluetooth module public key and trusted device data.

In some embodiments, the data verification may further include performing a device data repetition verification on the trusted device data. In some embodiments, the bluetooth module may send a plurality of pieces of trusted device data to the processing device, where there may be two or more pieces of identical duplicate data from one target device, and the device data duplicate checking may specifically refer to verifying whether the two or more pieces of data are identical duplicate data from one target device. In some embodiments, the trusted device data may include information such as a device identifier, a timestamp, etc. of the target device, where the device repetition check may be implemented by verifying whether the information such as the device identifier, the timestamp, etc. of the target device in the two or more pieces of data is the same, and if the information is the same, the same repeated data may be determined, otherwise, the repeated data is different data.

In some embodiments, the data verification may further include performing a data model verification on the trusted device data. In some embodiments, the bluetooth module may be device data acquired based on a data model agreed upon by the data service platform, which includes the data content to be acquired. Data model verification may refer to verifying the data content of trusted device data, verifying whether its data content complies with the data content specified in the data model, such as the specified data or data, and may also verify whether the data value of the data or data complies with the data format specification specified in the data model.

In some embodiments, data verification may also include numerical conversion of some parameters in the trusted device data (e.g., converting data values in decimal, 16-ary, etc. format to other types of readable data such as text), verifying whether some parameters in the trusted device data are accurate (e.g., parameters such as time stamps).

In some embodiments, the data verification may further include verifying the blockchain uplink identifier of the bluetooth module, for example, verifying whether the blockchain uplink identifier of the bluetooth module is valid, where the verification may be implemented to verify the identity validity of the bluetooth module, that is, whether the bluetooth module performs identity registration for data uplink.

In some embodiments, a data check is passed if all of the checks included in the data check are verified as passing. In some embodiments, if any of the checks included in the data check fails, the data check fails.

In some embodiments, the data service platform may implement the logging of trusted device data into the blockchain in a variety of possible ways as the data verification passes. As an example, the data service platform may send the certification transaction to the blockchain, which may include trusted device data (and may also include a trusted ID of the trusted device data, which may be an ID given by the data service platform to the trusted device data, different trusted device data having different IDs). When the authenticated transaction is transmitted to the blockchain network, nodes in the blockchain can verify the authenticated transaction based on a consensus algorithm, and the authenticated transaction containing the trusted device data is written into the blockchain. In some embodiments, for example, when the data size of the device data is large, the data service platform may further hash the trusted device data to obtain a hash value of the device data, and may write the hash value of the device data into the blockchain through the foregoing certification transaction.

In some embodiments, the blockchain may return the trusted device data to the blockchain's uplink result to the data service platform, which may also further return the uplink result to the processing device.

Through the embodiments, the trusted device data of the target device can be obtained through the bluetooth module arranged on the target device, the bluetooth module can send the trusted device data and the blockchain uplink identifier of the bluetooth module to the processing device through bluetooth communication, and the further processing device can interact with the data server to provide the trusted device data and the blockchain uplink identifier of the bluetooth module for the data server to store the trusted device data into the blockchain. Therefore, the method can realize the trusted acquisition and the blockchain trusted storage of the equipment data based on the existing or set more general Bluetooth module (such as the Bluetooth module set in the electronic car key of the rented electric bicycle) on the target equipment, and has wide application range and lower cost.

As shown in fig. 3, an interaction flow of a bluetooth module (e.g., bluetooth module 120), a processing device (e.g., processing device 130), and a data service platform (e.g., data service platform 140) is shown. In some embodiments, the processing device has a bluetooth communication function, the bluetooth module may perform bluetooth communication with the processing device, and the processing device may interact with the data service platform in a networking manner, so that the bluetooth module, the processing device, and the data service platform may participate in a related processing procedure for implementing the bluetooth module identity registration method in some embodiments of the present disclosure, so that identity registration of the bluetooth module may be implemented, so as to facilitate trusted uplink of trusted device data acquired by the bluetooth module.

The steps in the flow 300 of this specification are mainly described by taking the bluetooth module identity registration related flow (for example, steps 310, 320, 330, and 360) executed by the bluetooth module, and the bluetooth module identity registration related flow (for example, steps 340 and 350) executed by the processing device as examples.

The bluetooth module identity registration method 300 may include:

step 310, a bluetooth public-private key pair is generated.

In some embodiments the bluetooth module may perform identity registration related procedures automatically or based on an initialization request. As an example, the processing device may send an initialization request to the bluetooth module by performing bluetooth communication with the bluetooth module, and the bluetooth module may perform an identity registration related procedure based on the initialization request.

In some embodiments, after receiving the initialization request, the bluetooth module may first confirm whether the public-private key pair of the present party and the blockchain uplink identifier of the present party already exist in the present storage. If the public and private key pair and/or the blockchain uplink identifier of the method exist, the Bluetooth module can be indicated to successfully register the identity, and the identity registration can not be repeated. If the public and private key pair of the user does not exist, the public and private key pair of the user is generated, and if the blockchain uplink identifier of the user does not exist, the follow-up identity registration related flow is continued.

In some embodiments, the bluetooth module may include status information in the storage for indicating the identity registration status of the bluetooth module, and checking the status information may help determine whether the bluetooth module has successfully performed identity registration. For example, a state information being initialized may indicate that the bluetooth module has successfully performed identity registration, and a state information being uninitialized may indicate that the bluetooth module has not performed identity registration.

In some embodiments, the bluetooth module may receive multiple initialization requests sent by one or more processing devices, where one of the initialization requests (e.g., the first initialization request received by the bluetooth module) may be locked, and the bluetooth module may simply perform an identity registration related procedure based on the locked initialization request, wait for other initialization requests without lock, and unlock the locked initialization request after the identity registration related procedure corresponding to the locked initialization request is finished (e.g., after a bluetooth public-private key pair is generated). At this time, since the bluetooth public-private key pair already exists, the bluetooth module may not generate the public-private key pair based on other initialization requests. In some embodiments, the bluetooth module may further perform a de-registration process (e.g., the bluetooth module may still perform a subsequent identity registration process based on other initialization requests, but the data server may verify whether the bluetooth module has completed identity registration during identity registration, and if so, may not perform re-registration.

In some embodiments, in order to protect the public and private key pair by using the information security technology, after the bluetooth module generates the public and private key pair, the public and private key pair may be saved by using a secure storage method, and a specific description of the secure storage method of the key may be found in fig. 2 and related description thereof.

And 320, performing trusted processing on the identity information of the Bluetooth module based on a pre-stored private key of the data service platform to obtain trusted identity information, wherein the identity information comprises Bluetooth module equipment information and a Bluetooth module public key.

The bluetooth module may obtain identity information of the present invention, where the identity information may include bluetooth module device information and a bluetooth module public key, and the bluetooth module device information may include bluetooth module device identification information (e.g., device ID, device address MAC, IMEI number, etc.).

The data server may correspond to a public key (referred to as a data server public key) and a private key (referred to as a data server private key). The public key and the data server private key of the Bluetooth module are also a key pair, the data server public key can be issued outwards, the data server private key is held by the Bluetooth module and can be stored in the Bluetooth module in a safe and leak-proof transmission mode such as encryption transmission and the like so as to be used when registering the identity (for example, the data server private key is embedded in the Bluetooth module in a trusted third party embedding mode).

In order to protect the information security technology of the identity data, the Bluetooth module can perform trusted processing on the identity information based on a pre-stored private key of the data service platform to obtain trusted identity information.

In some embodiments, the trusted processing of the identity information by the bluetooth module based on the data server private key may include: the identity information is signed based on the data server private key. The Bluetooth module can generate a digest of the identity information based on a digest algorithm, and encrypt the digest with a private key of a data server to generate a digital signature, so that the security of the identity information is protected by signing. In some embodiments, the trusted processing of identity information by the bluetooth module may also include other processes that may secure identity information.

The trusted processing of identity information based on the data service platform private key may be similar to the trusted processing of device data based on the bluetooth module private key described above, and more specific details may be found in fig. 2 and related description.

And step 330, transmitting the trusted identity information to the processing equipment through Bluetooth communication with the processing equipment.

The bluetooth module may send the trusted identity information to the processing device by bluetooth communication with the processing device, so that the processing device may subsequently provide the trusted identity information to the data service platform to enable identity registration of the bluetooth module for data uplink.

Step 340, by interacting with the data service platform: and providing the trusted identity information so that the data service platform can register the identity of the Bluetooth module.

In some embodiments, the processing device may interact with the data service platform in a networked manner, the processing device may send the obtained trusted identity number to the data service platform, and the data service platform may perform identity registration of the bluetooth module.

In some embodiments, the identity registration related procedure performed by the data service platform may include: and performing a trusted verification on the trusted identity information, wherein the trusted verification is called a second trusted verification, and performing identity registration of the Bluetooth module based on the trusted identity information or not based on the result of the second trusted verification. For example, if the second trusted verification passes, the identity registration of the bluetooth module may be successfully performed, and if the second trusted verification fails, the identity registration of the bluetooth module may not be performed or the identity registration fails.

In some embodiments, as previously described, the trusted identity information may be signed based on a private key of the data service platform, and the second trusted verification may include: acquiring a digital signature of the trusted identity information; the digital signature is verified based on the data service platform public key and the trusted identity information.

In some embodiments, the data service platform may employ various possible identity registration methods to perform identity registration of the bluetooth module for data uplink of the bluetooth module. As an example, the data service platform may send a contract transaction to the blockchain, which may include trusted identity information, and may also include a trusted ID for the trusted identity information (the trusted ID for the trusted identity information may be an ID given by the data service platform for the trusted identity information, different trusted identity information having different IDs). When a contract transaction is transmitted to the blockchain network, nodes in the blockchain can process the contract transaction (which can include verifying the contract transaction), after the processing is completed (e.g., the contract transaction is verified, etc.), the blockchain can return a corresponding transaction hash to the data service platform, and the data service platform can determine a blockchain uplink identification of the bluetooth module based on the hash transaction (e.g., the hash transaction is used as the blockchain uplink identification).

Step 350, obtaining the blockchain uplink identifier determined by the data service platform after the identity registration is successful.

In some embodiments, if the identity registration of the bluetooth module is successful, it may obtain the blockchain uplink identification of the bluetooth module. The data service platform may return the obtained blockchain uplink identification to the processing device to cause the processing device to obtain the blockchain uplink identification.

Step 360, obtaining the blockchain uplink identifier by bluetooth communication with a processing device.

In some embodiments, the processing device may send the blockchain uplink identifier obtained after the identity of the bluetooth module is successfully registered to the bluetooth module by performing bluetooth communication with the bluetooth module.

Through the embodiments, the bluetooth module arranged on the target device can perform trusted processing on the identity information based on the pre-stored private key of the data service platform to obtain the trusted identity information, and the bluetooth module can send the trusted identity information to the processing device through bluetooth communication, and the further processing device can interact with the data service end to realize that the trusted identity information is provided to the data service end for identity registration of the bluetooth module for data uplink. Therefore, the trusted identity registration of the Bluetooth module connected with the target equipment can be realized, and further the trusted acquisition of equipment data and the trusted storage of the blockchain based on the more general Bluetooth module (such as the Bluetooth module arranged in the electronic car key of the electric bicycle for leasing) existing or arranged on the target equipment can be realized.
