Door lock control method and door lock based on two-factor authentication pattern

The present invention relates to a method of controlling a door lock based on a two-factor authentication pattern and a door lock based on a two-factor authentication pattern, and more particularly, when additional authentication of the user is not performed, the lock state of the door lock is switched to the unlock state or the unlock state is maintained By doing so, the user can receive help from outsiders (acquaintances, neighbors, security guards, security company employees, police, firefighters, etc.)

In particular, the present invention further configures an authentication means in the indoor module of the door lock, and controls the door lock based on the authentication pattern according to the outdoor authentication, indoor authentication, and opening and closing order of the door, thereby protecting the user's property and It relates to a method for controlling a door lock based on a two-factor authentication pattern to protect the body and a door lock based on a two-factor authentication pattern.

Door locks can be divided into mechanical door locks that open and close using metal keys and digital door locks that open and close using electronic keys, and digital door locks with high security and ease of use are mainly used.

The digital door lock can set or unlock the door lock by entering a password or using a magnetic card or IC card. Biometric technology is being developed.

The following prior art document, Republic of Korea Patent Publication No. 10-0919289 'A door lock device having an electric cover and a method for opening and closing the cover,' opens and closes the corresponding authentication means sequentially in order to proceed with the two authentication means in sequence. it was made to be

As such, most of the door lock-related technologies known so far, including the prior art, relate to an authentication means for locking and unlocking a door and a corresponding authentication method.

In other words, the technology related to the door lock so far has been developed focusing on how the user opens the door by using which authentication means.

However, one of the fundamental problems of the digital door lock occurs after unlocking the door. Specifically, it is as follows.

In most door locks, when a user enters a room by opening a door and then closes the door, there is a time interval from closing the door until the locking device of the door operates.

There is a problem that an outsider can invade during this time delay, and a dangerous situation in which an outside intruder is threatened may occur.

In particular, when an outsider follows the user when opening and closing the door as described above, the locking device of the door lock is activated and the user cannot release the lock by resisting the outsider, so that the inside and the outside are completely blocked. Therefore, there is a problem that the user does not receive any help from the outside.

Conversely, the same or similar problems as before may occur even when the user pushes the user in from the front door when the user goes out, or when the user intrudes under the guise of a visitor such as a delivery driver.

Recently, in a situation where the number of women living alone is increasing due to the increase of single-person households, the blind spots of these door locks can expose not only property damage but also physical risks, which is a very serious social problem. there is.

On the other hand, most commonly used door locks unlock the door by entering a number key from the outside.

As described above, even if the password is exposed and the user enters the room with an intruder already in, as described above, if the lock function of the door lock operates and cannot be released, the inside and outside are completely blocked. There is a problem with the state.

As a result, no matter what authentication means and authentication method is used, there is a way to prevent this in the case of intrusion immediately after the user returns home, pushing the user in while going out, or intruding under the guise of a visitor such as a courier. There is also a problem that there is no special solution for the state in which the intruder has already invaded.

In order to solve this problem, a separate method system must be configured, but in a private house, especially a studio for single-person households, it is practically impossible to build an expensive method system for each room, so it is always exposed to the above risks. there was no

Republic of Korea Patent Publication No. 10-0919289 'Door lock device with electric cover and opening and closing method of the cover'

In order to solve the above problems, the present invention additionally configures an authentication means in the indoor module of the door lock, and when additional authentication of the user is not performed, the locked state of the door lock is switched to the unlocked state or the unlocked state is maintained A door lock control method based on a two-factor authentication pattern that can help outsiders (acquaintances, neighbors, security guards, security company employees, police, firefighters, etc.) And it aims to provide a door lock based on a two-factor authentication pattern.

In particular, the present invention is a door lock control method based on a two-factor authentication pattern that can protect the user's property and body in an emergency situation by controlling the door lock based on the outdoor authentication, the indoor authentication, and an authentication pattern according to the opening and closing order of the door. And it aims to provide a door lock based on a two-factor authentication pattern.

In addition, the present invention secures additional authentication waiting time through graceful authentication when the door is opened for a certain period of time if necessary, or reassures the intruder by inputting a deceptive number when an intruder needs to enter an authentication number forcibly. An object of the present invention is to provide a door lock control method based on a two-factor authentication pattern and a door lock based on a two-factor authentication pattern that can actively respond to various situations by performing an alarm operation.

In order to achieve the above object, in the door lock control method based on the double authentication pattern according to the present invention, if any one of outdoor authentication and indoor authentication is normally performed, the validity and authentication location of the first authentication, which is the corresponding authentication A first authentication confirmation step of confirming; A door opening/closing confirmation step of sequentially confirming the opening and closing of the door; a second authentication confirmation step of confirming whether a second authentication is performed within a predetermined time after the door is opened or closed, and confirming a location where the second authentication has been performed; and whether to maintain the locked state to determine whether to maintain the locked state of the door lock after confirming the second authentication based on the confirmed first authentication position, opening and closing of the door, whether the second authentication is performed, and the second authentication position decision step;

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is the outdoor side and the door is opened and closed within the normal access time, the door lock is switched to the locked state, and then the second authentication position is the indoor When normal authentication is made on the side, the lock state of the door lock is maintained, and when normal authentication is not made on the indoor side, which is the second authentication position, the lock state of the door lock can be released.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is the outdoor side and the door is opened and closed within the normal access time, the door lock is maintained in the unlocked state, and the second authentication position is the indoor When normal authentication is made on the side, the door lock is switched to a locked state, and when normal authentication is not made on the indoor side, which is the second authentication position, the unlocked state of the door lock can be maintained.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is the outdoor side and the door is opened and closed within the normal access time, the door lock is switched to the locked state, and then the second authentication position is the outdoor When normal authentication is made on the side, the lock state of the door lock is maintained, and when normal authentication is not made on the outdoor side, which is the second authentication position, the lock state of the door lock can be released.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is the outdoor side and the opening and closing of the door is made within the normal access time, in a state in which the door lock is maintained in the unlocked state, the second authentication position is the outdoor When normal authentication is made on the side, the door lock is switched to the locked state, and when normal authentication is not made on the outdoor side, which is the second authentication position, the unlocked state of the door lock can be maintained.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is indoors and the opening and closing of the door is made within the normal access time, the door lock is switched to the locked state, and then the second authentication position is the outdoor When normal authentication is made on the side, the lock state of the door lock is maintained, and when normal authentication is not made on the outdoor side, which is the second authentication position, the lock state of the door lock can be released.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is indoors and the opening and closing of the door is made within the normal access time, in a state in which the door lock is maintained in the unlocked state, the second authentication position is the outdoor When normal authentication is made on the side, the door lock is switched to the locked state, and when normal authentication is not made on the outdoor side, which is the second authentication position, the unlocked state of the door lock can be maintained.

In addition, in the step of determining whether to maintain the locked state, if the first authentication position is indoors and the door is opened and closed within the normal access time, the door lock is switched to the locked state, and then the second authentication position is the indoor When normal authentication is made on the side, the lock state of the door lock is maintained, and when normal authentication is not made on the indoor side, which is the second authentication position, the lock state of the door lock can be released.

In addition, in the step of determining whether to maintain the locked state, when the first authentication position is indoors and the opening and closing of the door is made within the normal access time, in a state in which the door lock is maintained in the unlocked state, the second authentication position is the indoor When normal authentication is made on the side, the door lock is switched to a locked state, and when normal authentication is not made on the indoor side, which is the second authentication position, the unlocked state of the door lock can be maintained.

In addition, when a predetermined time has elapsed in a state in which the door is opened, a grace authentication waiting step of waiting for a grace authentication to delay the execution of the second authentication after a certain time has elapsed; further comprising, wherein the grace authentication waiting step includes: When the grace authentication is normally performed, the current state is maintained for a set grace time after the door is opened, and when the grace authentication is not normally performed, an alarm operation can be performed in response to the set alarm processor.

By means of the above solution, the present invention maintains the locked state of the door by the user's additional authentication in a state where the safety of the indoor space is guaranteed upon returning home. In an emergency, it is possible to receive help from outsiders (acquaintances, neighbors, security guards, security company employees, police, firefighters, etc.)

In addition, the present invention responds according to various situations, such as when an intruder breaks into the room while pushing the user in a situation where the user goes out, or when the corresponding visitor enters the room in a situation where the user checks the visitor from outside the room By doing so, there is an advantage in that it is possible to prevent and actively respond to various types of crimes.

More specifically, the present invention additionally configures an authentication means in the indoor module of the door lock, confirms the procedures for outdoor authentication, door opening and closing, and indoor authentication, and then switches the door lock to the locked state or locks it in response In order to maintain the state, and when indoor authentication is not performed for a certain period of time, there is an advantage of being able to request help from the outside by using an alarm sound, voice communication, and text message transmission.

Accordingly, the present invention suppresses the intruder with the help of an outsider in an emergency situation by maintaining the unlocked state of the door lock or releasing the locked state even when the user (resident) does not recognize or respond to the intrusion of an outsider. It has the effect of making it possible.

In particular, the present invention can induce an intruder to escape and protect the user's property and body by disclosing that a quick response is made by automatically connecting a call with the outside (security room, security company, police station, etc.) along with an alarm sound. It has the effect of making it possible.

In addition, the present invention does not install a separate security device or facility, but uses the basic devices and communication network (voice call and data communication) such as a door lock and a smart phone, thereby reducing the cost of installation and operation. There are advantages to minimization.

In particular, the present invention has the advantage that it is possible to obtain sufficient security and method effects with a low-cost device even in a vulnerable residential area where it is difficult to operate an expensive method system, such as a female-only studio in which women live alone. .

The two-factor authentication pattern-based door lock control method and the two-factor authentication pattern-based door lock examples according to the present invention can be applied in various ways. Hereinafter, the most preferred embodiment will be described with reference to the accompanying drawings.

1 is a flowchart illustrating an embodiment of a method for controlling a door lock based on a two-factor authentication pattern according to the present invention.

Referring to Figure 1, the door lock control method based on the two-factor authentication pattern is a first authentication confirmation step (S100), a door opening and closing confirmation step (S200), a second authentication confirmation step (S300), and a determining step ( S400), and unless otherwise specified, each step may be performed by the control module configured inside the door lock.

The first authentication confirmation step (S100) is a step of confirming the validity and authentication location of the first authentication, which is the corresponding authentication, when any one of the outdoor authentication and the indoor authentication is normally performed. Each authentication is performed using a key button. It can be performed by entering a number, and can be applied by changing to fingerprint recognition, pattern recognition, etc. according to the needs of those skilled in the art.

The door opening/closing confirmation step (S200) is a step of sequentially checking the opening and closing of the door, and information on whether the door is currently open, whether it has been opened or closed, and how much time has elapsed in the open state can be checked. The utilization of such information will be described in detail in the process of explaining the control method for each situation below.

The second authentication confirmation step (S300) is a step of confirming whether the second authentication is performed within a predetermined time after the door is opened or closed, and confirming the location where the second authentication has been performed. Together with ( S100 ), it may be a criterion for determining whether the user opened or closed the door for what purpose.

For example, when the first authentication location is the outdoor side and the second authentication location is the indoor side, it may be determined that the user has returned from going out. As another example, when the first authentication location is indoors and the second authentication location is outdoors, it may be determined that the user has gone out. As another example, when the location of the first authentication is indoors and the location of the second authentication is indoors, it may be determined that the door is opened when an outsider visits or to receive delivery or parcel delivery.

In the lock state maintenance determination step (S400), based on the confirmed first authentication position, door opening and closing, second authentication, and second authentication position, the maintenance of the locked state of the door lock after confirming the secondary authentication In the step of determining whether or not, the locking state of the door lock is released to prevent the user from being trapped in the indoor space by an intruder in a state in which the user is disconnected from the outside under certain conditions for the various situations discussed above.

Therefore, in an emergency, by asking for help while maintaining the door in an open state, it is possible to induce an intruder to escape and protect the user's property and body.

Hereinafter, the door lock control method for each situation will be described in more detail.

2 to 9 are flowcharts illustrating specific embodiments of FIG. 1 .

In the case of FIGS. 2 and 3, a situation in which the user enters the room from the outside, such as a situation in which the user returns from going out, will be described.

First, when the user completes outdoor authentication using the outdoor key button of the door lock (S110), opens the door, enters the room, and then closes the door (S210), the door lock may be switched to a locked state (S220) .

In other words, in a situation in which the user returns from going out, when the user enters the room and the door is closed, the door lock may be operated quickly to lock the corresponding door from being opened. Here, the time until the user opens the door and enters the room and then closes the door again in a state where no special situation occurs is referred to as the normal access time. can be determined and the door lock can be switched to the locked state.

After that, when the user performs indoor authentication (second authentication) within a certain time (S310) and the authentication is normally performed (S410), it is determined that the user's safety in the room is secured and the door lock is maintained in the locked state. It can be (S411). Here, the indoor authentication may be performed by at least one of a key button, a fingerprint input, and a pattern input.

If normal authentication is not performed on the indoor side, which is the second authentication location (S410), it is determined that there is an intruder or other special circumstances have occurred, and the lock state of the door lock can be released to receive help from the outside (S410). S412).

Thereafter, when the normal second authentication is performed, it goes without saying that the door lock can be switched back to the locked state.

At this time, as shown in FIG. 3 , it is possible to maintain the unlocked state of the door lock after opening and closing the door ( S210 ) ( S230 ). This is to prevent a case in which the door lock cannot be evacuated to the outdoors due to locking in an emergency situation, and whether the door lock is locked may be preset by the user.

When the door lock is maintained in the unlocked state as described above (S230), when normal authentication is performed on the indoor side (S421), it can be switched to the locked state (S422), and when normal authentication is not performed on the indoor side (S421) It is possible to maintain the released state (S423).

In the case of Figs. 4 and 5, it is for explaining a case where a user puts things inside the room from the outside, and a process for responding to an intruder according to the pattern of the two-factor authentication procedure will be described.

First, when the user completes the outdoor authentication using the outdoor key button of the door lock (S110), opens the door while the user is outdoors, puts the desired object into the room, and then closes the door (S210), the door lock It may be switched to the locked state (S220).

In other words, if the user has something to do outside while shopping or other reasons, when the user moves the item to the room and then closes the door, the door lock operates quickly to lock the door to prevent it from being opened. can

Thereafter, when the user performs outdoor authentication (second authentication) within a predetermined time (S320) and the corresponding authentication is normally performed (S410), the locked state of the door lock can be maintained (S411).

If normal authentication is not performed at the outdoor side, which is the second authentication location (S410), it is determined that a special situation such as a user is in danger has occurred, and the lock state of the door lock is released so that the user can evacuate to the room. It can be done (S412).

Thereafter, when the third authentication is performed on the indoor side, of course, the door lock can be switched back to the locked state.

At this time, as shown in FIG. 5 , it is possible to maintain the unlocked state of the door lock after opening and closing the door ( S210 ) ( S230 ). This is to prevent a case in which the user cannot quickly evacuate to the room due to the locking of the door lock in an emergency situation such as when the user is in danger, as described above. Whether the door lock is locked may be preset by the user.

If the door lock is maintained in the unlocked state as described above (S230), when normal authentication is performed on the outdoor side (S421), it can be switched to the locked state (S422), and when normal authentication is not performed on the outdoor side (S421) It is possible to maintain the released state (S423).

In addition, as described above, after evacuating the room in a dangerous situation, it goes without saying that the door lock can be switched back to the locked state when the third authentication is performed on the indoor side.

6 and 7 , this is to describe a situation in which a user goes out from an indoor environment, such as a situation in which the user goes out.

First, when the user completes the indoor authentication using the indoor key button of the door lock (S120), opens the door, goes outside, and then closes the door (S210), the door lock can be switched to the locked state (S220) .

After that, when the user performs outdoor authentication (second authentication) within a certain time (S320) and the authentication is normally performed (S410), it is determined that the safety of the user outside the door is secured and the door lock is maintained in a locked state It can be (S411).

If normal authentication is not performed on the outdoor side, which is the second authentication location (S421), it is determined that the user is in a dangerous situation, and the door lock can be released so that the user can quickly evacuate to the room (S412). ).

Thereafter, when the user evacuates to the indoor side to avoid danger, or when the risk outside the door is resolved and goes out again, the door lock can be switched to the locked state when normal secondary authentication is performed on the indoor or outdoor side.

At this time, as shown in FIG. 7 , after the door is opened and closed (S210), the door lock may be maintained in a released state (S230). In other words, in a situation in which the user goes out, if the user opens the door and goes outside, the door lock is maintained in a released state even if the door is subsequently closed. Here, the reason for maintaining the unlocked state of the door lock when going out is to allow the user to quickly evacuate to the room when an intruder is waiting in front of the door or a dangerous situation occurs in front of the door when going out.

If the door lock is maintained in the unlocked state in this way (S230), when normal authentication is performed on the outdoor side (S421), it can be switched to the locked state (S422), and when normal authentication is not performed on the indoor side (S421) It is possible to maintain the released state (S423).

In the case of FIGS. 8 and 9, the user opens the door to allow visitors from inside the room, or opens the door to receive goods such as delivery or parcel delivery, etc., in which the user is located indoors. This is to explain the situation in which the door is temporarily opened.

First, the user completes the indoor authentication using the indoor key button of the door lock (S120), receives an item after opening the door, or when a visitor enters and closes the door again (S210), the door lock is switched to the locked state can be (S220).

After that, when the user performs indoor authentication (second authentication) within a certain period of time (S310) and the authentication is normally performed (S410), it is determined that the user's safety is secured indoors, and the door lock can be maintained in a locked state. There is (S411).

If normal authentication is not performed on the indoor side, which is the second authentication location (S410), it is determined that the user is in a dangerous situation by an intruder disguised as a delivery man or courier, and the lock state of the door lock can be released (S412). ).

Thereafter, when the second authentication is normally performed on the indoor side, the door lock can be switched back to the locked state.

At this time, as shown in FIG. 9 , after opening and closing the door ( S210 ), it is possible to maintain the unlocked state ( S230 ).

In this way, in the state in which the door lock is maintained in the unlocked state (S230), when normal authentication is performed on the indoor side (S421), it can be switched to the locked state (S422), and when normal authentication is not performed on the indoor side (S421) ) can maintain the released state (S423).

Therefore, in various situations, by controlling the operation of the door lock according to the authentication pattern for each situation, the user's property and body are protected by preventing the user from being blocked from the outside in a situation where the user is trapped indoors in a dangerous situation and receiving help from the outside. can protect

10 is a flowchart illustrating another embodiment of FIG. 1 .

Referring to FIG. 10 , the method for controlling a door lock based on a two-factor authentication pattern of the present invention may further include a waiting step for deferred authentication ( S250 ) and a step of performing an alarm operation ( S500 ).

The grace authentication waiting step (S250) is a step of waiting for the grace authentication to defer the execution of the second authentication after a certain time has elapsed when a certain period of time has elapsed while the door is opened. This can be done if it is necessary to open for a period of time.

For example, when an item such as a parcel delivery service is placed in front of the door in a situation in which the user returns home after going out, it is necessary to open the door for a certain period of time in order to move the item into the room. As another example, it is necessary to open the door for a certain period of time in order to dispose of household waste or recyclables in a situation in which the user goes out. As another example, it is necessary to open the door for a certain period of time in order to move items such as delivery or courier service indoors or to move items brought by visitors into the room.

Such a deferred authentication standby step (S250) will be described in more detail below.

In the alarm operation performing step (S500), when the door lock is switched to the unlocked state or maintained in the unlocked state according to each situation by the above-described fund state maintenance determination step (S400), it is determined that the user is in a dangerous situation and a set alarm This is a step of performing an alarm operation in response to the process, which will also be described in more detail below.

11 is a flowchart illustrating a specific embodiment of step 'S250' shown in FIG. 10 .

Referring to FIG. 11 , when the door is opened after the first authentication is performed, the graceful authentication may be waited for a predetermined time ( S251 ).

In this case, if the grace authentication is normally performed (S252), the current state in which the door is opened may be maintained for a set grace time from the time the door is opened (S253). In other words, it is possible not to perform a separate step such as second authentication verification during the grace period.

After that, before the grace time elapses (S254), when the door is closed (S255), the second authentication by the indoor or outdoor authentication is waited for a certain period of time, and the second authentication is normally performed by the user. In the ground (S256), it is determined that the user has finished the desired business, and the door lock can be switched to the locked state (S257).

If the grace time has elapsed (S254), the door is closed (S255), and the normal secondary authentication is not performed (S256), it is determined that the user is in a dangerous situation and an alarm processor to be described below can be performed. (S258).

12 is a flowchart illustrating a specific embodiment of step 'S500' shown in FIG. 10 .

Referring to FIG. 12 , when a user's risk is detected for each situation as shown in FIG. 11 , the control module determines that it is a dangerous situation such as intrusion by an outsider ( S501 ), and an alarm operation such as outputting an alarm sound in response to a predetermined alarm process can be performed (S502).

At this time, if the current situation is due to the delay of the second authentication and is not a dangerous situation such as an outsider intrusion, the user may cancel the alarm operation (S503).

Accordingly, when the second authentication is performed or a separate release number is input (S503), the control module stops the output of the alarm sound (S507) and informs a helper or a related company that the dangerous situation is released. (S508). Here, the helper may include acquaintances and neighbors, security company employees, security guards, police officers, and the like. In addition, the release of the alarm operation is not limited to the method of inputting a release number by means of a key button, and may be changed to various authentication means and authentication methods according to a request of those skilled in the art.

On the other hand, if an alarm sounds in a situation where an outsider has invaded, the intruder may threaten the user and force the user to cancel the alarm.

Accordingly, when the user enters a deceptive number under the guise of canceling the alarm (S504), the external alarm operation such as the output of the alarm sound is stopped (S505), and the internal alarm operation to notify the helper or related company of the dangerous situation continues. It can be done (S506).

Therefore, the door lock of the present invention operates as if the alarm has been released externally to induce an intruder to be relieved, and to inform the emergency situation to helpers such as acquaintances and neighbors, related companies (security companies), police stations, guard rooms, etc. to quickly detect intruders. can be suppressed.

Of course, after the alarm sound is output (S502), even when both the release number and the deceptive number are not input (S503 and S504), it is possible to inform the helper or related companies that a dangerous situation has occurred (S506).

13 is a block diagram illustrating an embodiment of a door lock based on a two-factor authentication pattern according to the present invention.

Referring to FIG. 13 , the double authentication door lock 100 may include an outdoor module 110 , an indoor module 120 , a control module 130 , a lock module 140 , and a speaker 150 .

The outdoor module 110 receives outdoor authentication information by a user's manipulation, and may include an outdoor key button 111 .

The indoor module 120 receives indoor authentication information by a user's manipulation, and may include an indoor key button 121 for receiving numeric information, and is used to obtain user's fingerprint information according to a request of those skilled in the art. At least one of a fingerprint input unit 122 including an optical sensor and a pattern input unit 123 including a touch screen for receiving a pattern of a specific shape may be further included.

As such, it goes without saying that the fingerprint input unit and the pattern input unit configured in the indoor module 120 may also be configured in the outdoor module 110 .

In the case of the indoor module 120, as described above, deceptive authentication to deceive an intruder can be performed. For this purpose, two or more authentication means can be configured, and a release operation or a deceptive operation can be performed according to the authentication order of each authentication means. can be performed.

Of course, as shown in FIG. 12 , a release operation or a deception operation can be performed even by the indoor key button 121 as one authentication means, and a release operation (thumb fingerprint recognition) or deception can be performed using the fingerprint input unit 122. An operation (fingerprint recognition of the index finger) can be performed.

The control module 130 checks the chronological order of authentication made by the outdoor module 110 and the indoor module 120, and determines whether the first authentication position, opening/closing of the door, second authentication, and the second authentication are performed. Based on the location of the vehicle authentication, it is possible to determine whether to maintain the locked state of the door lock and whether to perform the alarm operation by the alarm processor according to the door lock control method shown in FIGS. 1 to 12 after confirming the location of the second authentication.

The locking module 140 is for controlling the locking state of the door, and may change the state of the door to the locked state or to the unlocked state by the operation of the solenoid 141 .

The speaker 150 is for outputting an alarm sound, and may output a voice if necessary. For example, when connected to the security room in case of a dangerous situation, it is possible to enable voice calls with the security guard, and for this purpose, a microphone can be further conceived.

In particular, the control module 130 'a dangerous situation has been received through the speaker 150 in order to disguise that a voice call is connected to the outside. Field agents will arrive in 5 minutes.' You can induce the intruder to escape by outputting a notice such as '.
