Entrance key managing system and method

The present invention relates to an entrance key management system that avoids unauthorized use of a barcode key displayed by using a mobile terminal.

Conventionally, there is a system in which a key barcode is sent to a visitor such as an apartment, and the visitor uses the barcode as a key at the time of admission (see, for example, Patent Document 1). In this system, it is possible that a malicious third party may copy the barcode key and misuse it.

In addition, there is a system in which a security function is provided assuming such a situation (see, for example, Patent Document 2). In this system, mobile terminals need to implement special security-specific features.<patcit num="1"><text>Japanese Unexamined Patent Publication No. 2004-360200</text></patcit><patcit num="2"><text>Japanese Patent Application Laid-Open No. 2005-120579</text></patcit>

<p> However, by using the barcode as a key, it is possible to unlock even a copy of the barcode in the unlocking and locking system for doors and entrance gates, and it is said that security was taken into consideration in response to such situations. However, when considering the operation, the terminal had to implement a dedicated function.</p><p> Therefore, an object of the present invention is to provide an entrance key management system and a method capable of avoiding unauthorized use of a barcode key displayed by using a general mobile terminal.</p>

<p> In order to solve the above-mentioned problems, in the present invention, the barcode reader installed at the entrance of the building is connected to the barcode key management device via a network, and when entering the building, the key barcode is carried. It is displayed on the LCD of the terminal and read by the barcode reader, and if there is a key managed by the barcode key management device, the entrance is unlocked.</p><p> This barcode key is obtained by displaying the URL that holds the image data of the barcode key with the Web browsing function, and this URL is notified from the barcode key management device by e-mail.</p><p> When a barcode key is used for unlocking, the barcode key management device immediately discards the key data and makes the same barcode key unusable. After that, a new barcode key is generated, and the URL in which the barcode key exists is sent to the mobile terminal by e-mail. These barcode keys and URLs are randomly generated.</p>

<p> According to the present invention, each time a barcode key required for entering a room is used, the barcode key used for unlocking is discarded, a new barcode key is created / registered, and the barcode key exists. Notify the URL to be used. It is possible to prevent a third party from referencing the URL by performing client authentication or user authentication of the mobile terminal when referencing this URL.</p><p> Also, since the barcode key used for unlocking and the URL where the barcode key exists are discarded and newly created, it is impossible to use it for unlocking even if the barcode key is illegally copied. ..</p><p> Furthermore, even if an unused barcode key is copied and used for unlocking, the URL containing the newly generated barcode key will be notified by e-mail to detect unauthorized intrusion. Is possible.</p><p> There is no need for a special terminal to display the barcode key, and the fact that a general mobile phone can be used as a terminal can be mentioned as an advantage.</p>

Next, the best mode of the present invention will be described with reference to the drawings.

FIG. 1 shows the system configuration of this embodiment, and is composed of a mobile terminal 101, a barcode reader 102, and a barcode key management device 103. The bar code reader 102 and the bar code key management device 103 are connected to each other via a network such as the Internet.

The mobile terminal 101 is intended for a portable device such as a mobile phone or a PDA, and has an e-mail function and a Web browsing function. In the present invention, an e-mail sent from the barcode key management device 103 is received, the URL described in the e-mail is displayed by the Web browsing function, and the image data of the barcode key existing in the URL is displayed. To do.

The barcode reader 102 is assumed to be a barcode reader arranged outside a gate or a door, reads a barcode key displayed by the mobile terminal 101, and uses the barcode key data as the barcode key management device 103. Is notified, and the door is unlocked when an unlocking command is returned from the barcode key management device 103.

The barcode key management device 103 manages the barcode key corresponding to each room. The barcode key management device 103 holds a database, and includes the barcode reader 102, the e-mail addresses of persons who are allowed to enter the room, the barcode key data for entering the room, and the bar. The URL where the code key exists is associated. When the bar code reader 102 notifies the bar code key, the unlock command is returned if the bar code key corresponds to the bar code reader 102. Further, a barcode key is generated and a URL in which the barcode key exists is generated and sent to the mobile terminal 101 by e-mail.

Next, the operation of this embodiment will be described in detail with reference to FIG.

[When registering / updating data]

When signing a contract to use a room, give the room manager (management company, real estate agent, landlord, etc.) the e-mail address of the mobile terminal 101 of the person who uses the room. The administrator registers this e-mail address in the barcode key management device 103 (S11). By this work, the barcode key management device 103 generates and registers a barcode key for the registered e-mail address (S12), and further generates and registers a URL in which the barcode key exists (S13). Send the generated URL to your email address (S14).

[At the time of admission]

When the occupant enters the room, he / she accesses the site of the URL held by the barcode key management device 103 notified by e-mail with a Web browser (S15), and the bar sent from the barcode key management device 103 (S16). The code key is displayed (S17), and the bar code key displayed on the mobile terminal 101 is held over the bar code reader 102 to attempt to unlock the entrance. The barcode reader 102 that has read the barcode key displayed on the mobile terminal 101 held over notifies the barcode key to the barcode key management device 103 (S18).

The barcode key management device 103 verifies the barcode key based on the ID of the barcode reader that has notified the barcode key and the data of the barcode key (S19). If the bar code key is a key held in the database of the bar code key management device 103 and the key is used in the correct room (bar code reader 102), the room is unlocked. Otherwise it returns an error (S20). If it is identified that the barcode key is used correctly (S20), the barcode key used for unlocking is discarded (S21), a new barcode key is created / registered (S22), and the barcode key exists. Create / register a new URL to be used (S23), and send the URL to the e-mail address associated with the barcode key used for unlocking (S24).

Through these processes, it is possible to introduce technologies such as client authentication and user authentication of mobile terminals when referencing a URL to obtain a barcode key, and it is possible to avoid referencing the URL by a third party. ..

Next, Example 2 of the present invention will be described with reference to FIG.

In the first embodiment, it was assumed that the entrance and exit were one room, but in this embodiment, there are multiple departments in one building such as a company, or multiple companies in one building. Imagine a building with multiple rooms inside, with different organizations using one gate, such as inside. FIG. 3 shows an example assuming this, in which a building gate and a door of each room exist as an entrance, and a barcode reader 102 is installed in the gate and each room.

In the first embodiment, when the barcode key is used to unlock the room, the barcode key is discarded and the URL of the newly generated barcode key is transmitted. In the example, when a barcode key is used to unlock the gate of a building, not only the barcode key of the gate but also the URL of the barcode key of each room according to the user who used the barcode key is sent. It is that.

[Company X a section employee]

When an employee of Section A of Company X unlocks the gate, the URL of the barcode key for the gate is newly sent, and the URL of the barcode key of the room of Company X and the server room of Company X is also sent. Also, if you use the barcode key to enter the two rooms, the URL of the barcode key of the room you entered will be sent.

[Company X b section employee]

When the employee of Section b of Company X unlocks the gate, the URL of the barcode key for the gate is newly sent, and the URL of the barcode key of the room of Company X and the server room of Company X is also sent. Also, if you use the barcode key to enter the two rooms, the URL of the barcode key corresponding to the room you entered will be sent.

[Company Y employee]

When an employee of Company Y unlocks the gate, the URL of the barcode key for the gate is newly sent, and the URL of the room barcode key of Company Y is also sent. Also, when the door of Company Y's room is unlocked, the URL of the barcode key for that door is newly sent.

[Visitor of Section b of Company X]

The visitor of the b section of the X company has the e-mail address of the mobile terminal 101 registered in advance by the employee of the b section of the X company, and the URL of the barcode key is also transmitted by this. When this visitor unlocks the gate, a new URL for the bar code key for the gate is sent, and the URL for the bar code key for the room in section b of company X is also sent. Also, when the door of the room in Section b of Company X is unlocked, the URL of the barcode key for that door is newly sent.

[Maintenance contractor]

Building maintenance contractors are authorized to enter all rooms for tasks such as cleaning and air conditioning adjustments, and when the gate is unlocked, a new URL for the gate barcode key is sent, and in addition The URL of the barcode key for all rooms will be sent. Also, if you use the barcode key when entering each room, the URL of the barcode key of the room you entered will be sent.

As described above, when the gate is unlocked, the URL of the barcode key to enter each room is sent according to the attributes of the person who unlocked the gate, so the barcode key is sent outside the building. Even if the copy is copied and misused, it is possible to avoid invasion of each room in it. It is also possible to restrict entry to unauthorized rooms in the building.

In addition to admission management for condominiums and other condominiums and office buildings, it can also be used for admission management for hotels and the like used by an unspecified number of people by using a general mobile phone as a terminal.
