Digital door lock having unique master key and method of operating the same

Abstract

Provided are a digital door lock having a unique master key and a method of operating the same. The digital lock can issue a master key, can be operated using a terminal having the master key and canbe operated using a terminal having a slave key distributed by a user of the terminal having the master key, regardless of whether the digital door lock is connected to a network.

Description

technical field [0001] The invention relates to a wireless communication device such as a digital door lock. In particular, it relates to a wireless communication device having a unique master key (Master Key) and capable of transmitting and receiving the master key and a terminal device through short-range wireless communication (Short-range Wireless Communication). Background technique [0002] As a conventional method of restricting qualifications for controlling a device, a lock may be mounted to the device, and the device can be controlled only when a key is inserted into the lock to become an ON state. However, the physical key has many inconveniences in that it is easy to copy, and it is necessary to actually provide the physical key in order to give others the control authority of the device. [0003] In order to solve the above inconvenience, the lock and key can be realized by software. For example, as an example of the device, there is provided a product develop...

AI Technical Summary

Problems solved by technology

However, the physical key has many inconveniences in that it is easy to copy, and it is necessary to actually provide the physical key in order to give others the control authority of the device, etc.

However, a server connected to the digital door lock is required, so it is useless if the digital door lock is not connected to the server

For example, in order to perform key services such as issuing keys to visitors from the user of the terminal to which the master key was issued, the master key is registered with the server when the master key of the digital door lock is issued, but the master key is not registered due to moving. In the case of setting up the Internet in the house, even the distribution of the master key of the digital door lock cannot be realized

[0005] Also, concerns were raised about scenarios where key data is compromised

In a case where key data for operating the digital door lock is leaked due to hacking or the like, the digital door lock may be improperly manipulated using the leaked key data
