Advantages and features of the present invention, and methods for achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention, and the general knowledge in the art to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used in a sense that can be commonly understood by those skilled in the art. In addition, the terms defined in the commonly used dictionaries are not ideally or excessively interpreted unless they are specifically defined clearly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. As used herein, "comprises" and / or "comprising" does not exclude the presence or addition of one or more other components in addition to the mentioned components.

In the present specification, the 'mobile terminal' or 'user client' includes all the various devices capable of performing arithmetic processing and providing a result to the user. For example, a computer can be a desktop PC, a notebook, as well as a smartphone, a tablet PC, a cellular phone, a PCS phone (Personal Communication Service phone), synchronous / asynchronous The mobile terminal of the International Mobile Telecommunication-2000 (IMT-2000), a Palm Personal Computer (PC), a Personal Digital Assistant (PDA), and the like may also be applicable.

In the present specification, the 'door lock device' refers to a device that performs door locking or unlocking. For example, a door lock device is a device that locks or unlocks a door of a specific space such as a building, a room, and a storage space.

Hereinafter, with reference to the drawings, the inaudible sound wave-based door lock management server, door lock device, door opening and closing authentication method and application in accordance with embodiments of the present invention will be described in detail.

1 is a block diagram of a door lock management system based on an inaudible sound wave according to an embodiment of the present invention.

2 is an internal configuration diagram of a door lock management server based on inaudible sound waves according to an embodiment of the present invention.

1 and 2, the door lock management server based on the inaudible sound wave according to an embodiment of the present invention, the authentication key data receiving unit 110; Authentication performing unit 120; And an open / close signal transmitter 130.

The authentication key data receiving unit 110 serves to receive authentication key data included in the inaudible sound wave signal transmitted from the first user client through a specific door lock device. The inaudible sound wave signal is generated and output at the time of opening and closing request at an inaudible frequency at the first user client. The authentication key data includes at least one of an authentication code of a first user client, time data of the opening and closing request point, and a command key. The command key is key data for controlling to lock or open the door lock.

The authentication code is used to distinguish the user client to open or close the door lock. The authentication code includes phone number authentication information, SNS authentication information or email authentication information. The phone number authentication information or the email authentication information is acquired or generated in the process of the user performing authentication in the application.

For example, when the user's mobile terminal is opened, the door lock authentication application performs a carrier authentication procedure through the telephone number according to the user's selection or recognition of the opening. Through this, the door lock application for authentication uses a code corresponding to the phone number itself or the phone number as the authentication code. In addition, for example, when the user's mobile terminal is not opened (for example, when using a Wi-Fi with an existing mobile phone without opening the phone when traveling abroad), the door lock authentication application may use an email or SNS account. User authentication is performed through the user, and a code corresponding to an e-mail account or an SNS account is obtained according to the authentication result.

In another embodiment, the authentication code further includes application identification information. For example, the application identification information may be identification information given for each application type. That is, when a number of services appear to authenticate the door lock based on the phone number, and the application is provided for each service, the door lock authentication application authenticates the application identification information to convey to the door lock that the application is a service application that can open and close a specific door lock You can include it in your code.

As another example, the application identification information is identification information given at application installation. When the user changes the mobile terminal (ie, changes from the first mobile terminal to the second mobile terminal), the application identification information provided when the door lock application is installed on the first mobile terminal and the door lock application on the second mobile terminal are newly installed. As the application identification information provided is different. Through this, the application identification information given to the user is changed by newly installing the door lock application in the new mobile terminal (ie, the second mobile terminal), and the door lock can be opened and closed by the first mobile terminal in which the door lock application was previously installed. When the first mobile terminal is acquired (for example, the first mobile terminal lost by the user), others may not be able to control the door lock opening and closing. When the user installs an application on another mobile terminal, the door lock management server may store new application identification information with the user information. The time data is used to determine whether the authentication key data is copied by another person. . The authentication procedure execution module 122, which will be described later, serves to distinguish the duplicated authentication key data using the time data. That is, since the time data in the duplicated authentication key data is different from the current time and the error range, the authentication procedure performing module 122, which will be described later, determines whether the time data in the authentication key data is duplicated.

The authentication performing unit 120 determines whether the door is opened or closed based on the authentication key data. The authentication performing unit 120 may determine whether the door lock device is opened or closed in various ways.

In one embodiment, the authentication performing unit 120, the authentication relationship storage module 121; And an authentication procedure performing module 122.

The authentication relationship storage module 121 matches the authentication code of the specific door lock device 200 and the specific first user client 300 and stores matching data. That is, the authentication relationship storage module 121 stores one or more first user clients 300 in which each door lock device 200 can be opened or closed.

The authentication relationship storage module 121 receives and stores matching data in various ways. As an example, the authentication relationship storage module 121 may be configured to include an authentication code corresponding to the first user client (for example, a phone number assigned to a mobile terminal corresponding to the first user client) and a specific door lock from a second user client. Receive identification information of the device, and stores the matching data. The first user client and the second user client may be the same user client, or may be different user clients.

When the second user client is a device distinguished from the first user client, the second user client requests the first user client to grant opening and closing authority of at least one door lock device. For example, the second user client may be a user client of a property owner having a plurality of rooms. The second user client generates matching data for the door lock and the first user client by transmitting an authentication code (for example, a telephone number) of the first user client provided from the user to a specific room desired by the user to the door lock management server. . Specifically, when using the phone number as the authentication code, as the phone number is provided to the door lock management server and stored as matching data, the door lock management server may be informed that the door lock opening and closing authority has been granted to the first user client through the phone number. have. In addition, in the case of the first user without a phone number, the first user client is provided at the time of authentication through e-mail or SNS, and provides the code registered in the door lock application to the second user client (for example, The registration code corresponding to the e-mail account or SNS account is displayed on the screen, or the first user client transmits the code to the second user client through various wireless communication methods, and the second user client identifies the door lock device to the door lock management server. The matching data is transmitted by storing the matching data. Also, for example, the second user client may be a client of a parcel delivery courier. The courier delivers the right to request to grant the right to open and close the door lock device to another user's client by registering the door lock management server. The second user client inserts the parcel delivery item of the specific first user into the storage space included in the specific door lock device, inputs a telephone number corresponding to the first user client, and identifies the identification information of the door lock device (or a specific space in the door lock device). Match the phone number and store the matching data. At this time, as the phone number is provided to the door lock management server and stored as matching data, the door lock management server has been granted the right to open and close the door lock to the first user client through the phone number (that is, the parcel delivery item within the storage space of the door lock device). Is stored).

In addition, for example, when a first user makes a reservation at a property that has a plurality of rooms, the first user uses an authentication code (for example, a telephone number or an email account) on a web page through the first user client. Or a code matched to an SNS account), the door lock management server matches and stores the identification information and the authentication code of the room to be reserved. At this time, the door lock management server may store the application identification information of the door lock application installed in the first user.

The authentication procedure performing module 122 serves to determine the opening and closing of a specific door lock device. First, the authentication procedure performing module 122 determines whether the matching data includes a door lock device that provides an authentication code (for example, a phone number) and authentication key data included in the authentication key data. For example, the door lock management server determines whether the phone number included in the authentication key data is included in the matching data, and if the phone number is included in the matching data, the door lock device identification information corresponding to the phone number is the authentication key data. Determine whether it matches the identification information of the door lock device transmitted.

In addition, when the authentication code includes the application identification code, the authentication procedure performing module 122 performs a process of determining whether the authentication key data provided by the service application associated with the door lock. That is, the authentication procedure execution module 122 extracts the application identification information included in the authentication key data, and determines whether the application identification information corresponding to the door lock service.

Thereafter, the authentication procedure execution module 122 determines whether the time data and the current time included in the authentication key data fall within an error range. The first user client acquires the authentication key data included in the inaudible sound wave signal itself or the inaudible sound wave signal generated at the first point in time by the first user client, and opens or closes the door lock at a second point in time after the first point in time. It is necessary to prevent the use. Accordingly, the first user client includes time data corresponding to the time point at which the request is made in the authentication key data, and the authentication procedure execution module 122 compares the current time with the time data in the authentication key data. Through this, it is possible to prevent the door lock opening and closing when the difference between the time data in the authentication key data and the current time becomes large.

The opening and closing signal transmitting unit 130 serves to transmit the opening and closing signal to the door lock device. That is, the open / close signal transmitting unit 130 is approved by the authentication key data received from the first user client and transmits the open / close signal to the door lock device to control the door lock device to be opened or closed.

The inaudible sound wave receiver 211 performs a function of acquiring an inaudible sound wave output from a user client. In one embodiment, the inaudible sound wave receiver 210 is activated after receiving a user operation on the door lock device. If the door lock device 200 continues to drive the inaudible sound wave receiver, the battery consumption may be fast, so that the inaudible sound wave receiver is contacted by a user to open or close the door lock by a user (eg, contacting the body with the door lock device). Or a button manipulation provided in the door lock device), the first audio client may be activated to receive inaudible sound waves provided from the first user client.

The wireless communication unit 212 transmits the non-acoustic sound wave to the door lock management server 100. The wireless communication unit 212 may process the non-acoustic sound as a digital signal and transmit the digital signal to the door lock management server 100, or may extract and transmit the authentication key data corresponding to the non-acoustic sound to the door lock management server 100.

In addition, the wireless communication unit 212 receives the door opening and closing information calculated based on the authentication code (for example, telephone number) and time data included in the authentication key data in the non-audible sound wave from the door lock management server 100 Play a role. That is, the door lock apparatus 200 does not directly determine whether the door lock is opened or closed, but the authentication code (eg, a phone number) and time included in the authentication key data in the door lock management server 100 through the wireless communication unit 212. Receive the result data (that is, door opening and closing information) determined by the data.

The controller 213 controls door opening and closing based on the door opening and closing information. That is, when the control unit 213 receives a result from the door lock management server 100 that the authentication code (for example, a phone number) and door lock identification information included in the authentication key data correspond to a matching relationship stored in the matching data, The door may be opened or closed at the request of the first user client 300.

Detailed description of the previously described configuration will be omitted.

The inaudible sound wave receiver 221 (same as 211) performs a role of acquiring an inaudible sound wave output from a user client.

The wireless communication unit 222 receives one or more authentication codes (eg, phone numbers) approved for opening and closing the door lock from the door lock management server. That is, the door lock device 200 is an authentication code corresponding to the first user client granted the control authority for a specific door lock device or a specific door in the door lock device from the door lock management server 100 to perform the door control by itself (eg For example, a telephone number). The wireless communication unit 222 may periodically receive an authentication code (for example, a phone number) of a user client having control authority, and a new user client has control authority or an existing user client adds control authority. If deprived, a verification code (eg, a telephone number) can be received in real time. In addition, when there are a plurality of user clients capable of controlling a specific door lock device or a door in the door lock device, the door lock device 200 may include authentication codes (for example, authentication codes) of a plurality of user clients having control authority through the wireless communication unit 222. , Phone numbers) and can be stored internally. For example, when the door lock device 200 is a device having a plurality of article storage space and has a door that can be opened and closed for each article storage space, the door lock device 200 can control the door of each article storage space Receive and store authentication codes (eg, phone numbers) of one or more user clients having authority through the wireless communication unit 222. That is, the door lock device 200 matches and stores authentication codes (eg, phone numbers) of at least one user client having each door and control authority thereto.

In addition, the wireless communication unit 222 may receive application identification information corresponding to the authentication code while receiving information on a specific door lock device or a door in the door lock device and one or more authentication codes corresponding thereto from the door lock management server. The door lock device 200 may prevent another person from controlling a specific door lock device or a specific door through a door lock application installed in an existing mobile terminal when changing the mobile terminal while maintaining a phone number through application identification information.

Figure 5 is a flow chart of the inaudible sound wave-based door opening and closing authentication method according to another embodiment of the present invention.

Referring to Figure 5, the non-audible sound wave-based door opening and closing authentication method according to another embodiment of the present invention, the door lock authentication application for obtaining the authentication code of the first user client (S200); And generating, by the door lock authentication application, authentication key data including the authentication code and time data at the time of the output request, and outputting an audible sound wave corresponding to the authentication key data. It includes; step (S400). Hereinafter, a detailed description of each step will be described.

The application for door lock authentication acquires an authentication code of the first user client (S200). The authentication code includes a phone number assigned to the first user client or a code obtained through an e-mail or an SNS messenger of the first user having the first user client. The phone number is embedded in a mobile terminal or USIM installed with a door lock authentication application or is input and stored by a user in the door lock authentication application. When the telephone number is directly input to the door lock authentication application by the user, the first user client may authenticate that the telephone number of the user client is passed through the telephone number authentication procedure.

In response to a user's door opening and closing request input, the door lock authentication application generates authentication key data including the authentication code (for example, a phone number) and time data at the time of the output request, and corresponds to the authentication key data. The non-audible sound wave is output (S400). The non-audible sound signal is generated by encoding authentication key data, and is obtained by the door lock apparatus and then transmitted to the door lock management server 100 to be used to determine whether the door lock is opened or closed.

In another embodiment, the non-audible sound wave output step (S400) is performed when the application for door lock authentication is close to the door lock device or recognizes the identification code of the door lock device. In addition to providing a non-acoustic signal to the door lock device, if the non-acoustic sound is continuously output, a pattern or an encryption method combining the telephone number and the time data in the authentication key data may leak to the outside, and thus the door lock of the first user client. It is necessary to prevent the audible sound wave signal from being output when the application for authentication does not approach the door lock device.

Thus, for example, the door lock authentication application is performed after the identification code (for example, QR code, barcode, etc.) attached to the door lock device or output on the screen of the door lock device is recognized. In addition, as another example, the door lock authentication application is performed after it is recognized that the door lock device 200 is approached by a beacon signal output from the wireless communication unit of the door lock device 200.

In another embodiment, the door lock authentication application generates authentication key data further including application identification information stored therein.
