Abstract

The present invention relates to a security-reinforced door lock, the security of which is reinforced, and a gate security management system using the same door lock, wherein: a double-unlock function using a security code stored in a user portable terminal, and a password input by a user's keystrokes may be provided so as to enhance user convenience; after a user enters or exits using a security code, the door lock itself may update the security code and the password together, generate multiple different passwords, and restrict the reuse of a single-used password or permit the reuse thereof only within a predetermined time, so as to allow the entry or exit of people who do not own a terminal in which a security code is stored, and prevent the leakage of the password; and multiple-visitor management for a door lock installed at a facility as well as a door lock for a single-woman household can be facilitated, and high security can be provided.

Dependent claims

A security-reinforced door lock, which is installed on a gate and locks and unlocks the gate, the security-reinforced door lock comprising:

a locking and unlocking means configured to lock or unlock the gate;
a keypad having numeric keys for the input of a password disposed thereon;
a short-distance communication module configured to communicate with a user portable terminal, in which a security code is stored, over a wireless local area network;
a security code reader unit configured to read the security code when the user portable terminal becomes close within a communication radius;
a password storage unit configured to store the password for locking or unlocking the door lock;
a security code storage unit configured to store the security code for opening or closing the door lock;
a locking and unlocking control unit configured to determine whether the security code read by the security code reader unit is identical with the security code stored in the security code storage unit or whether the password input through the keypad is identical with the password stored in the password storage unit and to change a state of the gate into an unlocking state by operating the locking and unlocking means when the security codes are identical or the passwords are identical;
and
a security code/password update unit configured to update both the security code and the password after the locking and unlocking control unit unlocks the locking and unlocking means by determining that the security codes are identical, to store the updated security code and the updated password in the security code storage unit and the password storage unit, respectively, and to transmit the updated security code and the updated password to the user portable terminal.

A gate security management system comprising:

a security-reinforced door lock installed on a gate and configured to lock and unlock the gate, the security-reinforced door lock comprising:
a locking and unlocking control unit configured to determine whether a security code read from a user portable terminal over a wireless local area network or a password input by a user is identical with a prestored security code or a prestored password and to change a state of the gate from a locking state to an unlocking state;
and a security code/password update unit configured to update both the security code and the password after the locking and unlocking control unit unlocks the locking and unlocking means by determining that the security codes are identical and to transmit the updated security code and the updated password to the user portable terminal;
a security management server configured to store and manage the security code and the password for each security-reinforced door lock, to perform a user authentication procedure when a request to issue the security code or a request to issue the password is received from the user portable terminal over a wide band mobile network, and then to remotely issue the security code or the password to the user portable terminal;
and
the user portable terminal configured to receive the updated security code and the updated password from the security-reinforced door lock and relay the updated security code and the updated password to the security management server,
wherein the security management server updates a security code management database and a password management database with the updated security code and the updated password relayed by the user portable terminal, respectively, and manages the updated security code and the updated password.
