Title: METHOD FOR GENERATING OFFLINE VERIFICATION CODE BASED ON SMART DOOR LOCK SYSTEM, AND SYSTEM THEREOF
Abstract:
A method for generating an offline verification code based on a smart door lock system, and a system thereof, the method comprising: in response to an unlocking event, a mobile terminal (701) records the trigger time of the unlocking event (S201); in response to the unlocking event, the mobile terminal (701) sends a request containing unlocking verification information to a cloud server (702), the request containing unlocking verification information being used for requesting the cloud server (702) to return a smart door lock (703) verification code, the unlocking verification information comprising a private key seed of a smart door lock (703) and the trigger time (S202); and the mobile terminal (701) receives the smart door lock (703) verification code generated by the cloud server (702) on the basis of the private key seed and the trigger time, and uses same to open the smart door lock (703). The present method solves the problem of a smart door lock (702) being unable to issue a password to open the door in situations including gateway power cuts, network disconnection, wireless faults, or not having a gateway installed, does not require the installation inside the lock of a communication module for interacting with a network gateway and a cloud server (72), and greatly reduces power consumption.
