Abstract

An authorization and unlocking method for a door lock is disclosed. A device binding operation is performed to bind a digital key to a digital door lock. The digital key is unlocked. The digital door lock is activated when the digital key is inserted into the digital door lock. It is determined whether the digital key is bound to the digital door lock. A network link between the digital door lock and the digital key is established if the digital key is bound to the digital door lock. It is determined whether the digital door lock is authorized by a remote authorization server. An unlock operation is performed on the digital door lock if the digital door lock is authorized by the remote authorization server.

Claims (45)

1. An authorization and unlocking method for a digital door lock executable by an electronic device, comprising:

performing a device binding operation to bind a digital key to the digital door lock;

unlocking the digital key;

activating the digital door lock when the digital key is inserted into the digital door lock;

determining whether the digital key is bound to the digital door lock;

establishing a network link between the digital door lock and the digital key if the digital key is bound to the digital door lock;

determining whether the digital door lock is authorized by a remote authorization server; and

performing an unlock operation on the digital door lock if the digital door lock is authorized by the remote authorization server.

2. The method of claim 1 , further comprising:

pressing and holding a start button of the digital key for a fixed time to enable the digital key to enter a binding mode;

inserting the digital key into the digital door lock to activate the digital door lock;

determining, by the digital door lock, whether the digital key is an approved device according to a first hardware identification code of the digital key;

returning, by the digital door lock, a second hardware identification code to the digital key, if the digital key is the approved device, and establishing the network link between the digital key and the digital door lock;

sending, by the digital door lock, binding data to the remote authorization server to complete the binding operation as the network link has been established;

receiving, by the remote authorization server, the binding data and responding with a binding code to the digital door lock; and

storing, by the digital door lock, the binding code and transmitting the binding code to the digital key.

3. The method of claim 1 , further comprising:

activating the digital key by a biometric identification to enable the digital key to enter an unlocking mode.

4. The method of claim 1 , further comprising:

rotating the digital key to activate the digital door lock when the digital key is completely inserted into the digital door lock and a positioning point of the digital key is pressed to a snap button of the digital door lock.

5. An authorization and unlocking system for a digital door lock executable by an electronic device, comprising:

a digital key, activated by a biometric identification;

the digital door lock, wherein the digital key and the digital door lock are bound according to a device binding operation; and

a remote authorization server,

wherein:

the digital key activates the digital door lock when the digital key is inserted into the digital door lock,

the digital door lock determines whether the digital key is bound to the digital door lock,

the digital door lock establishes a network link between the digital door lock and the digital key if the digital key is bound to the digital door lock, and

the remote authorization server determines whether the digital door lock is authorized and performs an unlock operation on the digital door lock if the digital door lock is authorized.

6. The system of claim 5 , wherein:

a start button of the digital key is pressed and held for a fixed time to enable the digital key to enter a binding mode,

the digital key is inserted into the digital door lock to activate the digital door lock,

the digital door lock determines whether the digital key is an approved device according to a first hardware identification code of the digital key,

the digital door lock returns a second hardware identification code to the digital key, if the digital key is the approved device, and the network link between the digital key and the digital door lock is established,

the digital door lock sends binding data to the remote authorization server to complete the binding operation as the network link has been established,

the remote authorization server receives the binding data and responds with a binding code to the digital door lock, and

the digital door lock stores the binding code and transmits the binding code to the digital key.

7. The system of claim 5 , wherein:

the digital key is activated by the biometric identification to enable the digital key to enter an unlocking mode.

8. The system of claim 5 , wherein:

the digital key is rotated to activate the digital door lock when the digital key is completely inserted into the digital door lock and a positioning point of the digital key is pressed to a snap button of the digital door lock.

9. An electronic device, comprising:

a binding module, configured to perform a device binding operation to bind a digital key with a digital door lock;

a detecting and activating module, configured to detect that the digital key is inserted into the digital door lock and activate the digital door lock, determine whether the digital key is a bound device, and, if the digital key is the bound device, establish a network link between the digital door lock and the digital key; and

an unlocking module, configured to determine whether the digital door lock has been authorized by a remote authorization server, and if the authorization is successful, perform an unlocking operation on the digital door lock.
