Most office furniture has a drawer for storing documents. If important documents need to be kept in a drawer provided with office furniture, the user of the office furniture usually locks the drawer with a key.

When office furniture having such a typical type of key-locking drawer is used, it is troublesome for the user to store the key, and the user may suffer from the loss of the key.

In addition, the keys provided in most office furniture are in a simple form, and the key clusters are exposed to the outside in many forms, so that the keys can be easily copied. Therefore, a problem that is very vulnerable to security has been raised.

Apart from the conventional simple key structure, office furniture with a key structure that is difficult to duplicate has also appeared. However, even if the security weakness is solved, there is still a hassle due to the possession and storage of the key.

In order to prevent the key from being held and stored, a system for opening and closing office furniture using fingerprint recognition and a system for opening and closing office furniture using an RFID (Radio Frequency Identification) system have been introduced.

By applying the methods using fingerprint recognition and RFID to the opening and closing of office furniture, the problem of security is solved, and the troubles due to the possession and storage of the key are eliminated. In the case of RFID, the user must carry a card containing the tag, but in the case of fingerprint recognition, there is no need to carry anything.

However, in the method using fingerprint recognition or RFID, the recognition device must be installed for each office furniture. Since the installation cost is excessive, it is difficult to use the device in a home or small business,

FIG. 5 is a flowchart illustrating an operation method of a security system for a depository using an authentication key according to an exemplary embodiment of the present invention. Referring to FIG.

Herein, an operation method of the security system using the authentication key shown in FIG. 1 will be described.

When the local area communication between the digital lock device 200 and the user terminal device 300 is activated (S701), the user terminal device 300 requests the authentication server 400 for authentication setting (S703). The authentication setting request of the user terminal 300 may be performed when the user logs in to the dedicated app or in a predetermined authentication key renewal period.

The authentication server 400 generates an authentication key according to a predetermined OTP scheme (S705), and transmits the authentication key to the user terminal 300 (S707).

When the authentication key is transmitted from the authentication server 400, the user terminal 300 stores the received authentication key in the storage unit 350 (S709). If there is an authentication key previously stored in the storage unit 350, the previous authentication key is discarded and a new authentication key is stored.

The user terminal device 300 transmits the authentication key stored in the storage unit 350 to the digital lock device 200 through the short-range communication unit 320 (S711).

When the authentication key is transmitted from the user terminal device 300, the digital lock device 200 receives the authentication key and stores it in the memory unit 230 (S713). At this time, if there is an authentication key already stored in the memory unit 230, the previous authentication key is discarded and a new authentication key is stored.

The digital lock device 200 releases the digital lock to the storage box 100 by the operation of the motor unit 220 (S715).

Thereafter, when the user terminal device 300 is disconnected from the local communication range and the local communication is disconnected (S717), the digital lock device 200 operates the digital lock lock for the storage box 100 by the operation of the motor unit 220 (S719).

When the user terminal device 300 and the digital lock device 200 are reconnected to each other in a short distance (S721), the user terminal device 300 transmits the authentication key stored in the storage unit 350 via the short- To the locking device 200 (S723).

When the authentication key is transmitted from the user terminal device 300, the digital lock device 200 compares the received authentication key with the authentication key previously stored in the memory unit 230 and performs authentication according to whether the authentication key is matched (S725).

If authentication between the two authentication keys is normally performed in the digital lock device 200, the controller 270 controls the motor unit 220 to release the digital lock of the locker 100 (S727).

The user terminal 300 receives the authentication key transmitted from the authentication server 400 and stores the authentication key in the storage unit 350 in step S809 and transmits the authentication key to the digital lock device 200 through the local communication unit 320 (S811).

When the digital lock device 200 receives the authentication key from the user terminal device 300, the digital lock device 200 stores the received authentication key in the memory 230 (S813).

The user terminal device 300 transmits the digital lock release signal to the digital lock device 200 through the dedicated app before the time of the start of the work (S815). Thereby, the digital lock device 200 releases the digital lock to the storage box 100 (S817). In addition, the user terminal device 300 transmits the user's arrival information to the attendance management server 500 (S819).

The time and attendance management server 500 stores the time and attendance information of the user, for example, the name of the employee and the time of work based on the time information transmitted from the user terminal 300 (S821).

Thereafter, the user terminal device 300 transmits a digital lock lock signal after the work-out time (S823). Thereby, the digital lock device 200 operates the digital lock lock for the storage box 100 (S825).

The close communication between the user terminal device 300 and the digital lock device 200 is disconnected due to the user's leaving work (S827), and the user terminal device 300 transmits the user's worker's home information to the time and attendance management server 500 (S829).

The time and attendance management server 500 stores the time and attendance information of the user, for example, the name of the employee and the time of work based on the user's worker information transmitted from the user terminal 300 (S831).

Although not shown in this embodiment, the step A described in the previous embodiment may be repeated several times between steps S813 and S823.

As described above, when the user terminal device 300 operates the locking and unlocking of the digital lock with respect to the storage, it is possible to manage the employee's working time and the work time by the requested time of the operation. Therefore, time and attendance recording can be performed without requiring a user to perform any operation, and it is not necessary to provide a separate device for time and attendance recording, which is very effective from the viewpoint of cost reduction.
