Technical Field

The present invention relates to the field of internet technologies, and in particular, to a method and a system for controlling an electronic lock based on a blockchain network, a request end, and a computer storage medium.

Background

Electronic locks have replaced traditional mechanical locks in many applications due to their ease of use. With the introduction of computers and communication technologies, electronic locks are becoming intelligent, for example, allowing unlocking using digital passwords, smart cards (IC cards, RFID cards, etc.), biometrics (e.g., fingerprints), and the like. Since an electronic lock typically allows multiple users to unlock at the same time or different users to unlock at different times, assigning unlocking privileges among multiple users, especially users of different interests, becomes a problem to be solved.

Taking a door lock as an example, in a rented house type scene, different unlocking persons such as a landlord, an operator and a tenant often have disputes about who has unlocking authority. At present, some house renting operators introduce a cloud management system to carry out unified management on users of the door locks and the door locks. However, the management system has the obvious characteristic of centralization, if the management system is not just, the distributed unlocking authority cannot be convinced by users of all interests, the reliability of the system is low, and the dispute of the unlocking authority cannot be solved.

Fig. 1 is a schematic structural diagram of an electronic lock control system based on a block chain network according to an embodiment of the present application. As shown in fig. 1, the electronic lock control system 10 includes an electronic lock 11, a request end 12, and a blockchain network system 13, and the blockchain network system 13 includes a first blockchain network 131, a second blockchain network 132, and a cross-chain bridge 133.

In the context of the present application, the electronic lock 11 may be a lock that is separate or attached to various carriers and may be manipulated by electronic control. In various embodiments, the electronic lock 11 may be opened by means of a password (e.g., characters), biometric features (e.g., fingerprints, faces, sounds), and the like. In the present embodiment, the electronic lock 11 may be an intelligent door lock. The electronic lock 11 itself does not include an unlocking verification function, and the request terminal 12 receives an unlocking operation including a password or a biometric characteristic and the like, and then transmits the password or the biometric characteristic and the like as a part of the user identification to the blockchain network system 13 for verification through the network. The following description will be given taking a password as an example.

In the present embodiment, the requesting end 12 may be a portable terminal, such as a smart phone, a smart bracelet, a smart watch, smart glasses, and the like. The request end 12 and the electronic lock can interact through wireless communication modes such as Bluetooth, radio frequency, zigbee and the like. The request end 12 is configured to trigger acquisition of a password of the user in response to an unlocking operation of the user. The requester 12 then generates an unlock request that includes a user identification associated with the requester, which may include a password for the user. The requesting end 12 then sends an unlock request to the first blockchain network 131 and reports an unlock request send event to the second blockchain network 132. The unlocking request sending event indicates that the request terminal 12 sends an unlocking request to the first blockchain network 131.

In another embodiment, the request 12 may be a module integrated in the electronic lock 11. The request end 12 and the electronic lock 11 may be connected by wire. The requesting end 12 may include input components (e.g., a keyboard, touch sensor, sound sensor, camera, etc.), a processor, and a communication module (e.g., a wireless communication module or a cellular communication module), among other modules, as necessary to perform the aforementioned functions.

Fig. 2 is a schematic illustration of an unlocking process according to an exemplary embodiment of the present application. As shown in fig. 2, in step S21, the request end 12 receives an unlocking operation of the user 200, for example, collects information (e.g., password) of the user as a user identifier. The request terminal 12 generates an unlocking request based on the unlocking operation and includes the user identification. In one embodiment, in order to protect sensitive information such as the password of the user, the request end 12 encrypts the collected password of the user, for example, calculates a Hash value of the password, and then includes the Hash value of the password and the user ID as the user identifier in the unlocking request. In step S22, the request end 12 sends an unlocking request including the user identifier to the first blockchain network 131 to trigger the first blockchain network 131 to perform unlocking and authentication operations, which will be described later. In step S23, the request end 12 reports an unlocking request sending event including the user identifier to the second blockchain network 132. The present application does not limit the encryption method of the password. In this embodiment, the Hash values of the messages are uploaded to the first blockchain network and the second blockchain network, and the original messages only exist in the request end. The privacy of the sensitive information is maintained while making full use of the sensitive information.

A blockchain network is a collection of a series of centerless nodes that incorporate new blocks into the blockchain in a consensus manner. As shown in fig. 2, a first blockchain network 131 may be configured in the service platform, and a second blockchain network 132 and a cross-chain bridge 133 may be configured in the supervisory platform. The first blockchain network 131 may be used to execute unlock-related contracts and the second blockchain network 132 may be used to execute verification-related contracts. The cross-link bridge 133 mediates the transfer of information from the first blockchain network 131 to the second blockchain network 132.

Due to the difference in function, the first blockchain network 131 and the second blockchain network 132 are set to networks of two different attributes. In this embodiment, the response time of the first blockchain network 131 is faster than that of the second blockchain network 132, and is the time required for the blockchain network to complete a request from the receipt of the request. For example, the response time of the first blockchain network 131 is in the order of seconds. The response time of the second blockchain network 132 is on the order of minutes, typically tens of minutes. In addition, the second blockchain network 132 has a higher degree of trust than the first blockchain network 131.

Further, as shown in fig. 2, the first blockchain network 131 is configured to receive an unlocking request of the request terminal 12; and executing unlocking intelligent contract C1 in response to the unlocking request to compare the user identification with the pre-registered user identification, and issuing an unlocking instruction to the request end 12 if the comparison is successful.

In the field of block chains, a Smart Contract (Smart Contract) is a computer protocol aiming at propagating, verifying or executing a Contract in an informatization mode, a developer formulates a set of rules through the Smart Contract, and then the rules are deployed on a line, a person interacts with the Smart Contract, and a machine completes part of a service, so that cheating behaviors possibly caused when the person executes the service are avoided. In this embodiment, some rules, such as unlocking verification, lock state message saving, lock user role and authority management of the first blockchain network 131, record unlocking request sending event of the second blockchain network 132, record lock state message, compare lock state message and unlocking verification message, etc., may be formulated in advance through an intelligent contract. The relevant contracts are then deployed onto the first blockchain network 131 and the second blockchain network 132, respectively. Specifically, the first blockchain network 131 compares the Hash value and the user ID of the received password with the Hash value and the user ID of the password registered by the user in advance by performing unlocking verification at step S24, and if the comparison is consistent, performs step S25 to issue an unlocking instruction to the requesting terminal 12, and at the same time, may perform step S26 to send the unlocking execution result to the second blockchain network 132. The sequence of step S25 and step S26 is not limited in the present application, and both may be executed simultaneously or sequentially, and the sequence of execution is not limited in the present application.

As shown in fig. 2, the request end 12 is further configured to receive an unlocking instruction issued by the first blockchain network 131 after the first blockchain network 131 is successfully verified, and then execute step S27 to forward the unlocking instruction to the electronic lock 11.

The second blockchain network 132 is configured to receive an unlocking request transmission event of the request terminal 12; receiving an unlocking execution result; and recording the unlocking request sending event. Specifically, the second blockchain network 132 records the unlocking request transmission event for subsequent evidence preservation supervision at step S28. The second blockchain network 132 may store and maintain the registered subscriber identity using the received unlock request to send events and/or other information.

The embodiment gives consideration to the reliability and the response time of decentralization through the double block chain network. The unlocking request is received through the first block chain network 131 with short response time to verify whether the unlocking request is successful, and if the verification is successful, an unlocking instruction is sent to the request terminal 12, so that the real-time requirements of control types such as unlocking and the like are well met. The second blockchain network 132 with high trust level is used for storing and certifying and monitoring the first blockchain network 131, and an alarm is given when the first blockchain network 131 is not trusted, so that the trust level of the whole blockchain system is ensured.

Fig. 3 is a schematic diagram of a lock state saving process according to an exemplary embodiment of the present application. As shown in fig. 3, the first blockchain network 131 is further configured to receive a lock status message of the requesting terminal 12 and/or the electronic lock 11. Specifically, when the electronic lock 11 has an IP network function and the electronic lock 11 can directly interact with the first blockchain network 131 in a communication manner, the electronic lock 11 is configured to encapsulate the lock status into a lock status message, and then execute step S31a to send the lock status message to the first blockchain network 131 and the second blockchain network 132, and correspondingly, the first blockchain network 131 is configured to receive the lock status message of the electronic lock 11. When the electronic lock 11 does not have the IP network function and cannot directly interact with the first blockchain network 131, the electronic lock 11 performs step S31b to report the lock status information to the requesting end 12, the requesting end 12 is further configured to receive the lock status information of the electronic lock 11, and then performs step S32 to send the lock status message to the first blockchain network 131 and the second blockchain network 132, and the first blockchain network 131 is configured to receive the lock status message of the requesting end 12. First blockchain network 131 then saves the lock status message in response to the lock status message at step S33.

The second blockchain network 132 is further configured to receive a lock status message of the requesting end 12 and/or the electronic lock 11. Similarly, the detailed description may refer to the configuration of the first blockchain network 131 according to whether the electronic lock 11 has the IP network function, and will not be described herein again. The second blockchain network 132 then performs lock status verification in step S35 in response to the lock status information of the requesting end 12 and/or the lock status information of the electronic lock 11. Specifically, the process of verifying the lock status may be comparing the received lock status information with the unlocking execution result stored on the second blockchain network 132, and if the received lock status information is consistent, the result indicates compliance, otherwise, the result indicates non-compliance. Generally speaking, the lock status message sent by the electronic lock is real, so if the unlocking execution result is inconsistent with the lock status message, it means that the first blockchain network 131 does not report the real unlocking execution result, and the reliability of the unlocking execution result is questionable, and the second blockchain network 132 thus records the comparison result for the supervision of the supervision platform where the second blockchain network is located on the service platform.

In some embodiments, the second blockchain network is further configured to issue an alarm when the unlocking execution result received from the first blockchain network 131 is found to be inconsistent with the lock status message received from the requesting terminal 12 and/or the electronic lock 11. The warning mode may be sending a warning instruction to the request end 12 and/or the electronic lock 11, the request end 12 and/or the electronic lock 11 receiving the warning instruction, and prompting the stakeholder in a vibration or sound mode, or displaying warning information through a display screen of the request end 12 and/or the electronic lock 11 to prompt the stakeholder, and the prompting mode is not limited in the present application. According to the method and the device, through the comparison and the verification of the electronic lock, the request end and the information ring of the first block chain network and the second block chain network, a certain part can be attacked and abnormal, and an alarm can be sent out in time. The safety factor of the system is improved, meanwhile, maintenance personnel can conveniently and quickly locate the abnormal position, and the maintenance difficulty is reduced.

Fig. 4 is a flowchart illustrating user registration according to an exemplary embodiment of the present application. As shown in fig. 4, the request end 12 is configured to trigger execution of step S41 to collect user information (e.g., password) in response to the registration operation of the user 200. A registration request is then generated and sent at step S42, the registration request including the user identification associated with the requesting end 12. In this embodiment, the user identification includes a user password Hash value and a user ID. The first blockchain network 131 is further configured to receive a registration request including the user identification, and in response to the registration request, the first blockchain network 131 performs lock user role and authority management, sets the user role and authority, and maintains the registered user identification at step S43. Specifically, the lock user role and authority management may be the following rules:

1) the roles of the lock users are as follows: landlord, operator (landlord) and tenant.

2) The landlord has the right to collect rent and the right to grant the role of an operator or a tenant, and once the landlord grants the role of other users, the right to unlock the landlord is recovered;

3) the operator has the right of collecting operation fee, house maintenance guarantee, lease invitation and charge, and the right of granting the role of tenant, once the operator grants the role of tenant to other users, the unlocking right is recovered;

4) the user is granted the tenant role and has independent lock opening and closing rights.

The multi-party cooperative control is introduced to the control of the door lock through the lock user role and the authority management contract, the real appeal of each right and interest party of the rental room type intelligent door lock is fully met, the transaction between each party and the lock can not be falsified, and meanwhile, the unlocking right of only one party is ensured at any time, so that the interest of each party is powerfully guaranteed. Moreover, the cooperation relationship of all parties of the intelligent door lock is bound by the intelligent contract, and the cooperation surrounding the lock is also driven by the intelligent contract to be executed; this also allows parties to complete contracts that can be signed at different locations and executed, greatly facilitating the labor costs of intelligent door lock management.

After the first blockchain network 131 performs lock user role and authority management, a user role and authority are set for each user. The user identification can be associated with the user role and the rights by the user ID. This allows for the user identity and user role and privileges to be certified on the first blockchain network 131. The format of the complete user registration information can be user ID, password Hash value, role and authority. The password Hash value is uploaded to the first blockchain network 131, and the original password exists only in the individual request terminal. The privacy of the sensitive information is maintained while the sensitive information is fully utilized. And the Hash value of the password of the electronic lock user is stored in the uplink, so that the electronic lock can be used for infinite times after being registered once, and the electronic lock does not need to be registered again if a tenant changes a house, thereby improving the experience satisfaction degree of the user.

The present application further provides an electronic lock control method based on a block chain network, which will be described below with reference to the accompanying drawings.

Fig. 5 is a flowchart illustrating a method 50 for controlling an electronic lock based on a blockchain network according to an exemplary embodiment of the present application, where the method may be performed by the above-mentioned blockchain network system 13, and as shown in fig. 5, the method 50 includes:
