Description

A method of controlling a locking device from a user terminal and a user terminal {USER DIVICE AND METHOD OF CONTROLLONG LOCKING DEVICE}

The present invention relates to a method of controlling a locking device in a user terminal, and more particularly, to a method of unlocking a locking device in a user terminal using a sound source for sound wave communication.

In general, a door lock system refers to a device that is installed at the entrance of a building and is unlocked when a user inputs a password, and automatically or manually locks when the user goes out. Recently used digital door locks are designed to be unlocked by inputting a password, fingerprint recognition, or contacting or proximity of an electronic key such as a memory card.

However, the input of the password may have poor security due to the exposure of the password, and user convenience may also decrease. In the case of fingerprint recognition, depending on the user, it may not be easy to use because the degree of fingerprint recognition decreases, and the electronic key is inconvenient to carry and may be lost. Accordingly, there is a need for a technology to allow the user to more conveniently unlock the lock.

In order to improve the above problems, research on a more convenient door lock system is continuing.

On the other hand, sound wave communication technology is a technology that sends digital information in a high frequency band sound that humans cannot hear. By using the sound of the high frequency band like Morse code, devices can exchange information without disturbing people by sending and receiving information.

Sound wave communication technology has a similarity with ACR (Auto Content Recognition) in that it identifies information through sound, but sound wave communication technology inserts a predefined sound signal in the inaudible area and detects it. It is different from ACR technology that finds the same content by analyzing the sound and comparing it with other pre-stored sound files. Sound waves in the non-audible area can be reliably recognized even at a low volume, and there is an advantage of being able to be recognized even among devices that cannot connect to communication.

Hereinafter, with reference to FIG. 2, a detailed description will be given of a detailed process in which the method of controlling the locking device 200 using the user terminal 100 in FIG. 1 is performed.

2 is a flowchart of a method of controlling a locking device using a user terminal according to an embodiment. The method of controlling the locking device 200 using the user terminal 100 according to the exemplary embodiment of FIG. 2 may be performed using the user terminal 100 and the locking device 200 illustrated in FIG. 1.

Referring to step S210 of FIG. 2, in the method of controlling the locking device 200 using the user terminal 100 according to an embodiment, the user terminal 100 may receive a sound source for sound wave communication. The user terminal 100 according to an embodiment may receive a sound source for sound wave communication from an external server connected through a network. For example, the external server may be a device that generates and provides a sound source for sound wave communication.

The user terminal 100 according to an embodiment, without a separate program or application, through a commonly used messenger program or text message (eg, MMS), also, a web browser, a social network (SNS) You can receive sound sources for sound wave communication through Internet environments such as Services).

In an embodiment, the user terminal 100 may play a sound source for sound wave communication received through a text message, and the locking device 200 may determine whether to release the lock based on information obtained from the reproduced sound source.

In an embodiment, the user terminal 100 may modify at least a part of the reproduced sound wave communication sound source. For example, a predetermined tag may be added to a specific position of the reproduced sound wave communication sound source, or noise may be added to a specific position of the reproduced sound wave communication sound source, but the method is not limited.

That is, the sound source reproduced once is deformed and cannot be reused, and even if it is shared with others, it is different from the original, so that it cannot be used for unlocking the locking device 200.

When a sound source for sound wave communication is obtained, the locking device 200 may check whether the sound source for sound wave communication is deformed, and release the lock only when an unmodified original is received.

For example, the user terminal 100 may receive and play a sound source for sound wave communication as an attachment file of a message transmitted through MMS or various messenger applications. The sound source for sound wave communication according to the disclosed embodiment may be generated and transmitted from a server, but is not limited thereto, and may be generated and transmitted from various types of master terminals. According to an embodiment, after the master terminal receives a sound source for sound wave communication generated from the server, it may be transmitted to the user terminal 100.

In an embodiment, when a sound source for sound wave communication is received and reproduced through an application, the user terminal 100 may include and reproduce the user's unique information in the sound source for sound wave communication.

When a sound source for sound wave communication is received, the locking device 200 may check not only the key information included therein, but also the unique information of the user, and unlock the lock only when the user is a registered user.

User information may be registered and stored in advance as family user information, and if access to a temporary user is required according to an embodiment, temporary user information may be registered in the locking device 200, and access to the temporary user The number of times allowed may be limited.

For example, the master terminal may be a terminal of a user who can grant permission to unlock the locking device. For example, the master terminal may correspond to a manager terminal of a locking device or a manager terminal of a lodging facility according to the disclosed embodiment, but is not limited thereto.

The master terminal may receive a sound source for sound wave communication generated from a server, or generate a sound source for sound wave communication, and transmit it to the user terminal 100 based on the above-described means.

In the disclosed embodiment, at least some or all of the configurations described as the operation of the server may be performed by the master terminal, and the master terminal may perform an operation of transmitting information to the user terminal alone, but received from the server An operation of transmitting information to the user terminal may be performed based on the information. In addition, it is also possible for the server to transmit information to the user terminal at the request of the master terminal, which is not limited.

The user terminal 100 may play a sound source included in the received message.

An embodiment based on such a master terminal can be utilized in various ways.

For example, the master terminal may be a terminal used by the owner of a furniture having a door on which a sound wave door lock is installed, and the user terminal may be a terminal used by a service employee who provides a delivery service for the corresponding furniture.

The master terminal may grant temporary or one-time unlocking rights to the acoustic door lock to the user terminal. For example, the master terminal transmits a message including a sound wave communication sound source capable of releasing the sound wave door lock to the user terminal, and the user terminal may unlock the sound wave door lock by playing a sound source for sound wave communication.

For example, in parcel delivery, registration, quick service, product delivery, etc., when the owner of the delivery target furniture is absent, the master terminal of the corresponding owner sends a message including a sound source for sound wave communication that can unlock the door lock at the door or the delivery box. Can be transmitted to the user terminal. The user terminal can unlock the door lock or the delivery box by playing a sound source for sound wave communication, and then put the product in the house or in the delivery box.

The above-described embodiment may be applied to a general door lock other than an acoustic door lock. For example, the master terminal sets a temporary password for the door lock, and the set temporary password is transmitted to the door lock through a Wi-Fi signal in the furniture. In addition, the master terminal transmits a temporary password to the user terminal, whereby the user can unlock the door lock or the delivery box, and then put the product in the house or in the delivery box.

For example, in the case of a sound wave door lock, the main unlocking method is sound waves, but when it is difficult to use sound waves or when the above embodiment is applied, a password (number) input as an auxiliary means may be provided to unlock the function. In addition, a temporary password setting function can be provided.

Through this, the master terminal can grant the right to temporarily unlock the door lock or the delivery box to an outsider, and when the door lock is opened through this, the door lock can transmit the information to the master terminal. That is, the door lock can transmit information on which an outsider opens and closes using a temporary password to the master terminal in real time.

Further, at least one camera device is installed around the door lock, so that an image until the door lock is unlocked and closed again can be captured. Through this, it is possible to monitor the behavior of outsiders in the process of opening and closing the door lock.

The user terminal 100 according to an exemplary embodiment may receive a sound source for sound wave communication from an external server that generates and provides a sound source for sound wave communication, and receives a sound source for sound wave communication from another user terminal storing and storing the sound source for sound wave communication. For example, in the case of providing accommodation services such as a hotel or a house used as a shared lodging business, or in the case of providing storage services such as unmanned lockers, unmanned courier boxes, unmanned mailboxes, safes, dressing room closets, etc., created on the server The sound source for sound wave communication is first transmitted to the terminal of the service provider, and may be transmitted from the terminal of the service provider to the terminal of the service user, that is, the user terminal 100 by the service provider.

The user terminal 100 according to an embodiment may receive a sound source for sound wave communication from an external server by transmitting information about the user terminal 100 to an external server and performing an authentication procedure.

The sound source for sound wave communication according to an exemplary embodiment may include password information on the locking device 200 and validity information on the validity of the password information. For example, the sound source for sound wave communication according to an embodiment may be obtained by converting password information and validity information for the locking device 200 encoded according to a predetermined rule into sound waves.

The validity information according to an embodiment is information for indicating whether a corresponding password is valid, and may include at least one of information indicating a valid period and information indicating an effective number of uses. For example, password information for the locking device 200 may be set to be periodically changed. Alternatively, according to the validity information, the password information for the locking device 200 may be a one-time (one-time) password, or a password whose number of uses is limited to a predetermined number of two or more times.

Validity information according to an embodiment may be set by a user or may be set as a default value.

For example, in the case of providing accommodation services such as a hotel or a house used as a shared lodging business, the service provider ensures that the password information included in the sound wave communication sound source provided to the user terminal 100 is valid only within the service contract period. Validity information can be set. In addition, when providing storage services such as unmanned lockers, unmanned courier boxes, unmanned mailboxes, safes, and dressing room closets, the service provider provides validity information so that password information included in the sound source for sound wave communication provided to the user terminal 100 is disposable. Can be set. The service provider can save the trouble of directly changing the password information of the locking device 200 when the service contract period expires.

Referring to step S220 of FIG. 2, in the method of controlling the locking device 200 using the user terminal 100 according to an embodiment, the user terminal 100 may reproduce a received sound source for sound wave communication.

The user terminal 100 according to an embodiment may reproduce a sound source for sound wave communication by a user input requesting to reproduce a sound source for sound wave communication. In addition, the user terminal 100 may automatically reproduce a sound source for sound wave communication when a predetermined condition is satisfied. For example, the user terminal 100 according to an embodiment may monitor a playback command for playing a sound wave communication sound source, and when a playback command is obtained, automatically play a sound wave communication sound source without an input from the user. A detailed method of automatically reproducing a sound source for sound wave communication by the user terminal 100 according to an embodiment will be described later with reference to FIG. 5.

The sound source for sound wave communication reproduced in the user terminal 100 according to an embodiment may be a sound source in an inaudible region. By using the sound source in the inaudible area, it is possible to make it difficult for others to attempt to duplicate the sound source, and thus security may be enhanced.

The user terminal 100 according to an embodiment may convert the received sound source for sound wave communication to reproduce the converted sound source for sound wave communication. For example, the user terminal 100 according to an embodiment may convert a received sound source for sound wave communication using current time information at which a sound source for sound wave communication is reproduced. The user terminal 100 according to an embodiment may convert a sound source for sound wave communication to further include current time information. The user terminal 100 according to an embodiment may convert a sound source for sound wave communication according to a predetermined rule based on current time information.

Security may be enhanced by reproducing a sound source for sound wave communication converted based on current time information in the user terminal 100 according to an exemplary embodiment. For example, if the password is not one-time, another person may attempt to duplicate the sound source. However, by converting and reproducing the sound source for sound wave communication based on the current time information that changes every time the sound source is reproduced, it is possible to make the sound source for sound wave communication duplicated by others invalid.

Referring to step S230 of FIG. 2, in the method of controlling the locking device 200 using the user terminal 100 according to an embodiment, the locking device 200 is a sound source for sound wave communication reproduced in the user terminal 100. Can be obtained. The locking device 200 according to an embodiment may acquire a sound source for sound wave communication through an input interface such as a microphone.

The locking device 200 according to an embodiment may obtain a sound source for sound wave communication before conversion by inversely transforming the sound source obtained through an input interface when the sound source for sound wave communication is converted and reproduced in the user terminal 100. The locking device 200 according to an embodiment may inversely transform the acquired sound source based on current time information at which the sound source is acquired through an input interface. Current time information at which a sound source used in the locking device 200 according to an embodiment is acquired may be the same as current time information at which a sound wave communication sound source used in the user terminal 100 is reproduced.

The locking device 200 according to an embodiment may play a copy-preventing sound source when the reproduction of the sound wave communication sound source from the user terminal 100 is identified. The locking device 200 according to an embodiment may further include an output interface such as a speaker to reproduce a copy-protected sound source. The copy-preventing sound source according to an embodiment may be a sound source for sound wave communication, such as being played in the user terminal 100.

For example, when the reproduction of the sound wave communication sound source from the user terminal 100 is identified, the locking device 200 according to an embodiment may reproduce the copy-preventing sound source so as to overlap with the sound wave communication sound source from the user terminal 100. have. Alternatively, the locking device 200 according to an embodiment may play a copy-protected sound source after the sound source for sound wave communication from the user terminal 100 is reproduced.

The locking device 200 according to an embodiment may randomly reproduce one sound source from among a plurality of copy-preventing sound sources.

By reproducing a copy-preventing sound source in the locking device 200 according to an embodiment, security may be enhanced. For example, if the password is not one-time, another person may attempt to duplicate the sound source, but when the user terminal 100 plays the sound source for sound wave communication including the password, the locking device 200 also plays the copy-protected sound source, It is possible to prevent others from replicating only the sound source for sound wave communication played back in the user terminal 100. For example, a sound source in which a sound source for sound wave communication reproduced in the user terminal 100 and a copy-prevention sound source reproduced in the locking device 200, reproduced by another person, is not effective for unlocking the locking device 200. May not.

The locking device 200 according to an embodiment, when the copy-protection sound source is reproduced, is reproduced from the user terminal 100 by removing the copy-protection sound source played by the locking device 200 from the sound source obtained through the input interface. A sound source for sound wave communication can be obtained.

Referring to step S240 of FIG. 2, in the method of controlling the locking device 200 using the user terminal 100 according to an embodiment, the locking device 200 is unlocked using the acquired sound source for sound wave communication. You can decide whether or not.

The locking device 200 according to an embodiment may determine whether to release the lock by comparing password information included in the obtained sound source for sound wave communication with password information previously stored by receiving from an external server. Alternatively, the locking device 200 according to an embodiment may determine whether to release the lock by transmitting the password information included in the obtained sound source for sound wave communication to an external server and passing through an authentication procedure.

The locking device 200 according to an embodiment may determine whether to release the lock using validity information included in the obtained sound wave communication sound source before authentication of the password information. For example, when it is indicated that validity information included in the obtained sound source for sound wave communication is not valid, the locking device 200 according to an embodiment may terminate the procedure without releasing the lock. When it is indicated that validity information included in the acquired sound source for sound wave communication is valid, the locking device 200 according to an embodiment may perform a procedure for authenticating password information included in the acquired sound source for sound wave communication.

The locking device 200 according to an embodiment, when the lock is released based on the password information included in the acquired sound wave communication sound source, the locking device 200 based on the validity information included in the acquired sound wave communication sound source. Password information stored in advance can be updated. For example, when the validity information indicates that the corresponding password information is one-time use, the locking device 200 may determine to discard the password previously stored in the locking device 200 upon unlocking. When the validity information indicates that the number of times of use of the password information is limited to a predetermined number of two or more times, the number of times of use of the password information previously stored in the locking device 200 may be stored according to the unlocking of the lock.
