[0115] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0116] like Figure 1 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to an electronic lock. The method includes:

[0117] Step 101: Obtain the unlocking transaction identifier generated by the blockchain.

[0118] The blockchain distinguishes different unlocking transactions through unlocking transaction identifiers. For example, the current user can initiate different unlocking transactions to the blockchain at different time points. The blockchain can distinguish different unlocking transactions through unlocking transaction identifiers. The unlocking transaction identifier can be a transaction hash. In some application scenarios, the smart contract address can also be used as the unlocking transaction identifier.

[0119] Step 102: Send the unlocking transaction identifier and the stored public key of the lock owner to the server.

[0120] The lock owner's public key can be pre-stored in the electronic lock by the lock owner. The server can obtain the authorized user's public key and unlocking transaction result from the blockchain based on the unlocking transaction identifier. The lock owner's public key is used to verify the identity of the authorized user. If the authorized user's public key is the same as the lock owner's public key, it means that the authorized user is the lock owner.

[0121] The unlocking transaction results include success or failure. The success of the unlocking transaction is used to indicate that the unlocking transaction has passed the verification of the blockchain, and the failure of the unlocking transaction is used to indicate that the unlocking transaction has not passed the verification of the blockchain.

[0122] Step 103: Receive the verification result sent by the server.

[0123] Step 104: Determine whether to unlock the door based on the verification result.

[0124] The verification result is used to indicate whether the unlocking transaction is legal. If it is legal, the electronic lock is opened; otherwise, the electronic lock remains closed.

[0125] In one embodiment of the present invention, the method may further include: sending an unlocking result notification to the access terminal. For example, if the electronic lock is opened, the electronic lock sends an unlocking success notification to the access terminal, otherwise it sends an unlocking failure notification.

[0126] In an embodiment of the present invention, the electronic lock can provide the unlocking transaction identifier to the server, so that the server can obtain the unlocking transaction related information from the blockchain according to the unlocking transaction identifier, thereby verifying the unlocking transaction. In this process, the electronic lock does not transmit information such as private keys or temporary passwords to other parties, preventing such information from being obtained by illegal users, thereby improving the security of the electronic lock.

[0127] In one embodiment of the present invention, sending the unlocking transaction identifier and the stored public key of the lock owner to the server includes:

[0128] The unlocking transaction identifier, the stored public key of the lock owner and the identifier of the electronic lock are sent to the server.

[0129] Considering that a lock owner may own multiple electronic locks, in order to distinguish authorized electronic locks, the embodiment of the present invention also provides the identifier of the current lock to the server.

[0130] like Figure 2 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to a server, including:

[0131] Step 201: receiving the unlocking transaction identifier and the public key of the lock owner sent by the electronic lock.

[0132] Step 202: Obtain the unlocking transaction result and the public key of the authorized user from the blockchain according to the unlocking transaction identifier.

[0133] Step 203: Verify the unlocking transaction according to the unlocking transaction result, the public key of the authorized user and the public key of the lock owner.

[0134] Step 204: Send the verification result to the electronic lock.

[0135] The server verifies the legitimacy of unlocking transactions from multiple angles, which can improve the security of electronic locks.

[0136] In one embodiment of the present invention, the unlocking transaction is verified according to the unlocking transaction result, the public key of the authorized user and the public key of the lock owner, including:

[0137] Determine whether the unlocking transaction is successfully executed according to the unlocking transaction result. If yes, determine whether the public key of the authorized user and the public key of the lock owner are the same. If yes, determine that the unlocking transaction verification is passed.

[0138] The embodiments of the present invention can conveniently verify the legitimacy of the accessing user, the validity of the unlocking transaction, etc. based on the unlocking transaction result. Based on the comparison between the public key of the authorized user and the public key of the lock owner, it can be determined whether the authorized user is the lock owner. The unlocking transaction can be verified from the perspectives of the authorized user and the accessing user, thereby improving the security of the electronic lock. In actual application scenarios, it is also possible to first determine whether the public key of the authorized user is the same as the public key of the lock owner. If they are the same, then determine whether the unlocking transaction is successfully executed based on the unlocking transaction result. Of course, the two verification processes can also be performed simultaneously.

[0139] In one embodiment of the present invention, receiving the unlocking transaction identifier and the public key of the lock owner sent by the electronic lock includes:

[0140] Receiving the unlocking transaction identifier, the public key of the lock owner and the identifier of the electronic lock sent by the electronic lock;

[0141] Obtain the unlock transaction result and the public key of the authorized user from the blockchain according to the unlock transaction identifier, including:

[0142] Obtain the authorized lock identifier, unlocking transaction timestamp, unlocking transaction result, and authorized user's public key from the blockchain according to the unlocking transaction identifier;

[0143] If the public key of the authorized user is the same as the public key of the lock owner, the method further comprises:

[0144] Determine whether the identification of the authorization lock and the identification of the electronic lock are the same. If so, determine whether the time interval between the timestamp of the unlocking transaction and the current time is within a preset time threshold. If so, perform a check to determine whether the unlocking transaction has passed.

[0145] The embodiment of the present invention verifies the validity of the unlocking transaction through the timestamp of the unlocking transaction, ensuring the safety of the electronic lock after the time threshold has passed. The lock identification verifies whether the electronic lock is an authorized lock to avoid affecting the safety of other locks of the lock owner. The public key of the lock owner verifies whether the authorized user is the lock owner to prevent illegal users from impersonating the lock owner to authorize other users.

[0146] like Figure 3 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to an access terminal. The method includes:

[0147] Step 301: Send an unlock transaction to the blockchain.

[0148] If the user wants to open the electronic lock, he needs to send an unlocking transaction to the blockchain through the access terminal to trigger the blockchain to execute the unlocking method.

[0149] Step 302: Obtain the unlock transaction identifier generated by the blockchain based on the unlock transaction.

[0150] Step 303: Provide the unlocking transaction identifier to the electronic lock.

[0151] The access end triggers the verification process of the blockchain and the server by initiating an unlocking transaction. This verification process is implemented based on the blockchain, which can prevent the rights and interests information of the electronic lock from being tampered with and improve the security of the entire control process.

[0152] In one embodiment of the present invention, providing the unlocking transaction identifier to the electronic lock includes:

[0153] A QR code is generated according to the unlocking transaction identifier; and the QR code is displayed so that the electronic lock can obtain the unlocking transaction identifier by scanning the QR code.

[0154] In the embodiment of the present invention, the electronic lock can obtain the unlocking transaction identification more conveniently by scanning the QR code. In the actual application scenario, the electronic lock can also obtain the unlocking transaction identification by scanning the barcode. The current user can also view the unlocking transaction identification through the installed access terminal and manually input the unlocking transaction identification into the electronic lock.

[0155] like Figure 4 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to an authorization end, and the method also includes:

[0156] Step 401: Send a create contract transaction to the blockchain so that the blockchain deploys a smart contract according to the create contract transaction.

[0157] Step 402: Send a transfer transaction to the blockchain, so that the blockchain transfers the resources in the contract account from the authorized user to the access user according to the transfer transaction.

[0158] The authorized user can publish the resources to be authorized to the access user to the blockchain by creating a contract transaction. The resources in the contract account are used to represent the key of the electronic lock. The authorized user can transfer the resources in his contract account to the access user through a transfer transaction, that is, transfer the key of the electronic lock to the access user. The embodiment of the present invention stores the key of the electronic lock in the form of resources in the blockchain, and the authorized user can authorize other users to use the key of the electronic lock through the authorization terminal. Due to the immutability of the blockchain, the key of the electronic lock can be circulated more safely between users, ensuring the safety of the electronic lock.

[0159] like Figure 5 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to blockchain. The method includes:

[0160] Step 501: Deploy the smart contract in the blockchain according to the create contract transaction sent by the authorization end.

[0161] Step 502: According to the transfer transaction sent by the authorization end, the resources in the contract account are transferred from the authorized user to the access user.

[0162] Step 503: Call the smart contract according to the unlock transaction sent by the access terminal to generate an unlock transaction identifier and an unlock transaction result.

[0163] Among them, the public key of the authorized user, the unlocking transaction identifier and the unlocking transaction result are stored correspondingly.

[0164] The blockchain stores the keys of electronic locks in the form of resources. Authorized users transfer the keys of electronic locks by transferring resources, and the owner of the resources has the right to unlock the locks. Users can initiate unlocking transactions for the resources in their accounts. For example, the resources in user A's account represent the keys of electronic lock a. If user A wants to open electronic lock a, user A initiates an unlocking transaction, which is used to call the smart contract corresponding to the resource. In one embodiment of the present invention, the transfer transaction includes: accessing the public key of the user;

[0165] Smart contracts also include: validity period;

[0166] The smart contract is called according to the unlock transaction sent by the access end to generate the unlock transaction identifier and unlock transaction result, including:

[0167] Verify whether the current user is the access user based on the public key of the access user. If so, call the unlocking method in the smart contract to determine whether the current time is within the valid time period. If so, generate an unlocking transaction identifier and an unlocking transaction result to indicate that the unlocking transaction is successfully executed.

[0168] The authorized user and the access user can agree in advance on a valid time period, for example, 14:00-18:00.

[0169] In the embodiment of the present invention, the unlocking transaction is signed with the private key of the accessing user. Therefore, the embodiment of the present invention verifies the signature by the public key of the accessing user to determine whether the current user who sends the unlocking transaction is the accessing user who holds the resource. The present invention verifies the unlocking transaction from the two perspectives of valid time and accessing user to improve the security of the electronic lock. In the actual application scenario, it is possible to first verify whether the current time is within the valid time period, and then verify whether the current user is the accessing user. The two verification processes can also be verified simultaneously.

[0170] In one embodiment of the present invention, the smart contract is an NFT (Non-Fungible Token) smart contract, and the resource is an NFT. In actual application scenarios, NFTs can be issued on the blockchain based on ERC-721, ERC-1155 protocols, etc. NFTs can be used as key certificates to facilitate transfers. If an authorized user authorizes multiple electronic locks, multiple smart contracts can be deployed in the blockchain, and each smart contract corresponds to an NFT.

[0171] like Figure 6 As shown, an embodiment of the present invention provides a lock control method based on blockchain, which is applied to an electronic lock. The method includes:

[0172] Step 601: Obtain the unlocking transaction identifier generated by the blockchain.

[0173] Step 602: Obtain the unlocking transaction result and the public key of the authorized user from the blockchain according to the unlocking transaction identifier.

[0174] Step 603: Verify the unlocking transaction according to the unlocking transaction result, the public key of the authorized user and the stored public key of the lock owner.

[0175] Step 604: Determine whether to unlock the door based on the verification result.

[0176] The embodiment of the present invention integrates the functions of the server in the above embodiment into the electronic lock, shortens the control process and improves the control efficiency. The server is separated from the electronic lock to reduce the cost of the electronic lock.

[0177] In one embodiment of the present invention, the unlocking transaction is verified according to the unlocking transaction result, the public key of the authorized user and the stored public key of the lock owner, including:

[0178] Determine whether the unlocking transaction is successfully executed according to the unlocking transaction result. If yes, determine whether the public key of the authorized user and the public key of the lock owner are the same. If yes, determine that the unlocking transaction verification is passed.

[0179] In one embodiment of the present invention, obtaining the unlocking transaction result and the public key of the authorized user from the blockchain according to the unlocking transaction identifier includes:

[0180] Obtain the authorized lock identifier, unlocking transaction timestamp, unlocking transaction result, and authorized user's public key from the blockchain according to the unlocking transaction identifier;

[0181] If the public key of the authorized user is the same as the public key of the lock owner, the method further comprises:

[0182] Determine whether the identification of the authorization lock and the identification of the electronic lock are the same. If so, determine whether the time interval between the timestamp of the unlocking transaction and the current time is within a preset time threshold. If so, perform a check to determine whether the unlocking transaction has passed.

[0183] like Figure 7 As shown, an embodiment of the present invention provides a blockchain-based lock control method, which is applied to a blockchain-based lock control system. The method includes:

[0184] Step 701: The authorization end sends a create contract transaction to the blockchain.

[0185] The access user and the authorized user communicate in advance to determine the valid time period, such as 8:00-9:00.

[0186] Step 702: The blockchain deploys a smart contract based on the creation of the contract transaction; wherein the smart contract includes the public key of the authorized user.

[0187] This smart contract is an NFT smart contract, which records the following information: the identification of the authorized lock, the effective time period, the public key of the authorized user, and the unlocking method. Call the unlocking method to execute: determine whether the current time is within the effective time period. If so, the unlocking transaction result is successful, otherwise, the unlocking transaction result is failed. The signature of the NFT owner must be held when calling the unlocking method, that is, the unlocking transaction must be signed with the private key of the access user. The public key of the authorized user and the identification of the authorized lock are not allowed to be modified, but the authorized user can modify the effective time period.

[0188] The creation contract transaction is signed with the private key of the authorized user. The blockchain can verify whether the creation contract transaction is initiated by the authorized user based on the public key of the authorized user included in the creation contract transaction. If the public key carried in the creation contract transaction does not match the private key used for the signature, the blockchain will not respond to the creation contract transaction to prevent illegal users from endangering the security of the electronic lock.

[0189] After the smart contract is deployed on the blockchain, an NFT is obtained in the contract account, which can be transferred to other users.

[0190] The authorization end and the access end may be a blockchain wallet, or other applications that can implement the embodiments of the present invention.

[0191] Step 703: The authorization end sends the transfer transaction to the blockchain.

[0192] Before step 703, the guest user provides his public key to the authorized user, which can be done verbally or through the access terminal. The transfer transaction may include the address of the contract account, the public key of the authorized user, and other information.

[0193] Step 704: The blockchain transfers the resources in the contract account from the authorized user to the accessing user based on the transfer transaction.

[0194] After the smart contract is deployed on the blockchain, the authorized user can view the NFT he holds through the blockchain wallet and transfer it to the visiting user through the blockchain wallet. After the blockchain transfers the NFT from the authorized user to the visiting user, the visiting user can receive the NFT from the authorized user in his blockchain wallet.

[0195] The transfer transaction is signed with the private key of the authorized user, and the blockchain can verify whether the transfer transaction is legal based on the public key of the authorized user.

[0196] In actual application scenarios, a transfer transaction may also include a transfer method, which determines whether the transfer transaction is signed with the private key of the authorized user. Specifically, the blockchain calls the transfer method in the smart contract according to the transfer transaction to determine whether the transfer transaction is signed with the private key of the authorized user. If so, the resources in the contract account are transferred from the authorized user to the access user.

[0197] The smart contract can also include the attribute: owner, which is used to record the holder of the electronic lock key, that is, the holder of the resource.

[0198] Step 705: The access end sends an unlocking transaction to the blockchain.

[0199] The access end sends an unlocking transaction to the blockchain for the NFT held by the accessing user, and the unlocking transaction is signed with the accessing user's private key.

[0200] Step 706: The blockchain calls the smart contract according to the unlocking transaction and generates an unlocking transaction identifier and an unlocking transaction result; wherein the authorized user's public key, unlocking transaction identifier and unlocking transaction result are stored correspondingly.

[0201] The blockchain calls the unlocking method in the smart contract according to the unlocking transaction and obtains the unlocking transaction result and transaction hash.

[0202] Step 707: The access end obtains the unlocking transaction identifier and provides the unlocking transaction identifier to the electronic lock.

[0203] The access end queries the blockchain and obtains the transaction hash. The electronic lock obtains the transaction hash by scanning the QR code.

[0204] Step 708: The electronic lock sends the unlocking transaction identifier and the stored public key of the lock owner to the server.

[0205] The electronic lock sends the pre-stored lock owner's public key and transaction hash to the server.

[0206] Step 709: The server obtains the unlocking transaction result and the public key of the authorized user from the blockchain according to the unlocking transaction identifier, verifies the unlocking transaction according to the unlocking transaction result, the public key of the authorized user and the public key of the lock owner, and sends the verification result to the electronic lock.

[0207] Step 710: The electronic lock determines whether to unlock based on the verification result.

[0208] For the unlocking transaction initiated by the current user, on the one hand, the blockchain verifies whether the current user is an authorized user based on the smart contract. On the other hand, the server or the electronic lock can determine whether the authorized user is the lock owner by comparing the public key of the lock owner with the public key of the authorized user. The verification results of the above two aspects are combined to determine whether to open the electronic lock, which can improve the security of remote control of the electronic lock. The embodiment of the present invention saves the ownership of the electronic lock in the blockchain in the form of resources to prevent the ownership of the electronic lock from being obtained by illegal users. At the same time, temporary passwords or private keys of authorized users and other information are not transmitted in the network, further improving the security of the electronic lock.

[0209] like Figure 8 As shown, an embodiment of the present invention provides a lock control method based on blockchain, including:

[0210] Step 801: The authorization end sends a create contract transaction to the blockchain.

[0211] Step 802: The blockchain deploys a smart contract based on the creation of the contract transaction; wherein the smart contract includes the public key of the authorized user.

[0212] Step 803: The authorization end sends a transfer transaction to the blockchain.

[0213] Step 804: The blockchain transfers the resources in the contract account from the authorized user to the accessing user based on the transfer transaction.

[0214] Step 805: The access end sends an unlocking transaction to the blockchain.

[0215] Step 806: The blockchain calls the smart contract according to the unlocking transaction and generates an unlocking transaction identifier and an unlocking transaction result; wherein the authorized user's public key, unlocking transaction identifier and unlocking transaction result are stored correspondingly.

[0216] Step 807: The access end obtains the unlocking transaction identifier and provides the unlocking transaction identifier to the electronic lock.

[0217] Step 808: The electronic lock obtains the unlocking transaction result and the public key of the authorized user from the blockchain according to the unlocking transaction identifier, verifies the unlocking transaction according to the unlocking transaction result, the public key of the authorized user and the stored public key of the lock owner, and determines whether to unlock the lock according to the verification result.
