In one embodiment, after detecting the status update record of the smart cabinet A, the cross-chain server 120 will compare the current usage status of the smart cabinet A and the identification number of the electronic device 140 with the lock information to confirm the smart lock. Cabinet A is locked.

Next, the control method 400 of the IoT device then executes step S436 , after the verification of the lock information is successful, the cross-chain server 120 updates the smart contract corresponding to the selected IoT device 130 . In one embodiment, after confirming that the smart cabinet A has been locked, the cross-chain server 120 will update the smart contract corresponding to the smart cabinet A to update the status of the smart cabinet A. For example, if the smart cabinet A is locked and The status that is in use can be "locked in use".

Next, the control method 400 for the IoT device then executes step S437 , the cross-chain server 120 transmits the status corresponding to the selected IoT device 130 to the electronic device 140 , and updates the status corresponding to the selected IoT device 130 in the merchant server 150 . In one embodiment, after updating the smart contract, the cross-chain server 120 will transmit the status corresponding to the smart cabinet A to the electronic device 140 , and update the status corresponding to the smart cabinet A in the merchant server 150 .

In another embodiment, the user may also choose not to reserve the IoT device 130, that is, the process of step S410 is not performed, and only the processes of steps S420-S430 are performed, since step S420 is to unlock the IoT device 130 and step S430 is to The IoT device 130 is locked. Therefore, in general, the process of step S430 usually occurs together with the process of step S420. Only in special abnormal situations, step S420 will occur independently of step S430, for example, the user does not close the cabinet. The door, or the unlocking of the cabinet door is abnormal, etc.

From the implementation of the above case, it can be seen that this case is mainly to improve the management rigidity and security and privacy disputes of the previous centralized management, and the existing non-centralized management mechanism cannot conduct real-time transactions due to the long blockchain transaction time. The IoT device contract management service is used to retain the features of centralized management, flexible deployment, and data security and reliability, enabling instant interaction of IoT devices, and reducing the cost of IoT device development and deployment.

Additionally, the above illustrations contain sequential exemplary steps, but the steps do not have to be performed in the order shown. It is within the contemplation of this disclosure to perform the steps in a different order. These steps may be added, replaced, changed order and/or omitted as appropriate within the spirit and scope of the embodiments of the present disclosure.

Although this case has been disclosed above in terms of implementation, it is not intended to limit this case. Anyone who is familiar with this technique can make various changes and modifications without departing from the spirit and scope of this case. Therefore, the protection scope of this case shall be The scope as defined by the appended claims shall prevail.
