DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the configuration of a terminal use restriction system will be described with reference to FIGS. 1 to 3. FIG. FIG. 1 is a configuration diagram of a terminal use restriction system according to an embodiment of the present invention, FIG. 2 is a block diagram illustrating a configuration of a group source terminal included in a terminal use restriction system according to an embodiment of the present invention, 3 is a block diagram illustrating a configuration of a server included in a terminal usage restricting system according to an embodiment of the present invention.

1, the terminal usage restricting system according to an embodiment of the present invention includes a member terminal 10 and an administrator terminal 20, 25 that exchange data with each other via a network N, And a server 40 for providing the server 40 with information.

The network N may be a local area network (LAN), a wide area network (WAN), a value added network (VAN), a personal area network (PAN) mobile radio communication network, Wibro (Wireless Broadband Internet), Mobile WiMAX, HSDPA (High Speed Downlink Packet Access) or satellite communication network.

The member terminal 10 may be implemented as a portable terminal that can be connected to a remote server through the network N or connectable to other terminals and servers. Here, the portable terminal is, for example, a wireless communication device that is guaranteed to be portable and mobility, and includes a PCS (Personal Communication System), a PDC (Personal Digital Cellular), a PHS (Personal Handyphone System), a PDA (Global System for Mobile communications), IMT (International Mobile Telecommunication) -2000, Code Division Multiple Access (CDMA) -2000, W-CDMA (W-CDMA), Wireless Broadband Internet (WIBRO) ), Mobile Worldwide Interoperability for Microwave Access (WiMAX), and the like.

Here, 'member' is a group member belonging to a specific 'group', and is a user registered in the server 40 as a member of a specific group through the administrator terminals 20 and 25 to be described later.

At this time, the member terminal 10 is provided with a use restriction application for restricting the execution of a specific function of the member terminal 10 or restricting the use of the entire terminal according to a command of the server 40, When a certain time comes according to the execution of the usage restricting application or when a use restricting command by push notification is received from the server 40, the use of the terminal is restricted by using the lock function of the terminal. At this time, the use restriction application may be downloaded and installed in a general application market (for example, an application store or a play store), or may be provided in an embedded form in the member terminal 10. [

On the other hand, the administrator terminals 20 and 25 can be implemented in a computer, a portable terminal, or a television, which can be connected to a remote server through the network N or connected to other terminals and servers. Here, the computer includes, for example, a notebook computer, a desktop computer, a laptop computer, and the like, each of which is equipped with a web browser (WEB Browser), and the portable terminal may be a wireless communication device , Personal Communication System (PCS), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), Personal Digital Assistant (PDA), Global System for Mobile communications (GSM), International Mobile Telecommunication (IMT) (W-CDMA), Wibro (Wireless Broadband Internet), Smart Phone, Mobile WiMAX (Mobile Worldwide Interoperability for Microwave Access) (Handheld) based wireless communication device. In addition, the television may include an Internet Protocol Television (IPTV), an Internet television (TV), a terrestrial TV, a cable TV, and the like.

The administrator terminals 20 and 25 access the server 40 as an administrator of the group registered in the server 40 and restrict the usage of the terminals collectively or individually for each member terminal 10 registered as a member .

At this time, the administrator terminals 20 and 25 can be divided into two different terminals according to the embodiment.

In the case where a plurality of members subordinate to one group do not form a small group again, the manager terminals 20 and 25 need not be distinguished from each other. However, when a plurality of members subordinate to one group account form a small group again , The manager terminals 20 and 25 are provided with a contact person terminal 20 that manages each small group and an operator terminal 25 that manages all the members of one group account and manages the contact persons depending on the group account ).

At this time, the representative terminal 20 and the operator terminal 25 are not distinguished by the hardware configuration. It is assumed that the account used for accessing the server 40 is a representative account dependent on one group account, The representative terminal 20 and the operator terminal 25 can be distinguished according to whether the account is the one having the highest level of authority for the group account.

For example, a single unified school account may be assigned to one school, and an operator account that manages these school accounts at the highest level of authority may be assigned to the school account, A teacher account can be assigned to manage students. A student account may also be granted for each student.

The portable terminal that accesses the server 40 in the student account through the use restriction application is the member terminal 10 and the terminal that accesses the server 40 through the operator account is the operator terminal 25, The terminal accessing the server 40 through the account of the teacher of FIG. 1 may be the representative terminal 20 in FIG.

In addition, as described above, in the case where the manager of a specific group is not classified into the manager and the manager, the distinction between the manager terminal 20 and the operator terminal 25 is unnecessary in FIG. 1 and can function as one component.

On the other hand, the server 40 is a computer capable of communicating with a remote terminal or another server. The server 40 transmits and receives data to and from the member terminal 10 and the administrator terminals 20 and 25 via the network N, And the manager terminal 20 or 25 provides information on whether or not the terminal of each member is locked.

The server 40 communicates with the use restriction application installed in the member terminal 10 and can communicate with the manager application installed on the manager terminals 20 and 25 or the manager web page provided on the manager terminals 20 and 25 .

In the following description, the member terminal 10 is described as a student terminal 10, the representative terminal 20 is represented as a teacher terminal 20, a specific group is limited to a school, The configuration will be described in more detail, but it goes without saying that the present invention is not limited to this embodiment.

Referring to FIG. 2, the student terminal 10 includes an instruction receiving unit 11.

The command receiving unit 11 receives a lock command from the server 40. [ At this time, the server 40 may transmit the same lock command to the students belonging to the specific school or a specific class of the specific school at the same time, or may transmit the same lock command to the students belonging to the specific class according to the setting of the teacher terminal 20 or the operator terminal 25 Lt; / RTI >

At this time, the lock command may include information on the lock start time and the lock release time. In addition, the lock command may include only information on one lock and release, or may include schedule information on a plurality of lock and unlock operations. Alternatively, the lock command does not include information on the lock start time or the lock release time, but may simply include an instruction to simply switch the student terminal 10 to the locked state. In this case, the student terminal 10 may switch the state of the terminal to the locked state immediately upon receipt of the lock command.

The command receiving unit 11 may store information on the lock time and the lock release time included in the received lock command in the student terminal 10.

Alternatively, the lock command may be received at the lock start time with the push notification or as a push notification to the student terminal 10. So that the use restriction application described above can be executed in the confirmation process of the push notification. That is, the server 40 can send a push notification to each student terminal 10 at the lock start time set by the teacher terminal 20 or the operator terminal 25, thereby allowing the student to execute the use restriction application by itself, The application may access the server 40 and receive the lock command. In addition, the lock command can be transmitted to the student terminal 10 through a Short Message Service (SMS) or a Multimedia Message Service (MMS) via a general mobile communication network. In this case, the message by SMS or MMS may include a lock command in a form recognizable by the use restriction application described above. When the SMS or MMS message is received, the use restriction application installed in the student terminal 10 can confirm whether or not the lock command is included in the data included in the message, and when the lock command is included, And the lock performing unit 13, respectively.

The student terminal (10) may be provided with a lock guide (12). The lock guide unit 12 can inform the student about the lock start time or the lock release time included in the received lock command before the arrival of the lock start time.

When the lock start time arrives, the lock guide unit 12 informs that the lock start time comes, and before the lock performing unit 14, which will be described later, restricts the use of the student terminal 10, You can query whether to accept the lock.

At this time, if the push notification is received by the student terminal 10, the lock guide 12 may instruct the student to arrive at the lock start time by displaying a message included in the push notification.

The lock accepting unit 13 provided in the student terminal 10 notifies the lock accepting unit 12 of the acceptance of the lock acceptance request from the student You can get an acceptance sign. That is, the lock accepting unit 13 provides the user with a message to inform the student that the student who is the user of the student terminal 10 agrees with the function lock of the terminal, , And if the student selects the 'confirm' button as the 'accept' command, the server 40 is notified that the student has accepted the lock.

Accordingly, when the student accepts the lock, the lock performing unit 14 restricts the function of the terminal. The lock performing unit 14 restricts the usable functions of the student terminal 10 when the student accepts the lock after the lock start time comes. Of course, according to the embodiment, the lock start time may not be set separately, and the lock may be performed as soon as the lock command is received.

The lock performing unit 14 may switch the student terminal 10 to the locked state by using the terminal lock function provided through the application programming interface (API) of the terminal, for example.

In this case, the 'locked state' means that a general function of the student terminal 10 can be used only when a password or the like is input or a predetermined pattern is input, and only limited functions such as an emergency telephone can be performed until the student terminal 10 is released.

At this time, the server 40 sets a lock pattern such as a password for each student terminal 10, and transmits the lock command to the student terminal 10 by including the lock pattern. When the lock receiving unit 14 receives the lock pattern from the server 40 and stores the lock pattern in the lock state, the command receiving unit 11 transmits the lock pattern received from the server 40 The lock state can be set in advance so as to be releasable.

Alternatively, the lock performing unit 14 may generate a lock pattern by itself and perform locking using the lock pattern.

However, when the server 40 generates a lock pattern for a specific student terminal 10, information on the generated lock pattern is transmitted to the teacher terminal 20, which is the person in charge of the group or small group corresponding to the corresponding student terminal 10 So that the student can be released from the locked state by allowing the teacher to notify the student after checking the lock pattern when it is urgently needed.

At this time, the lock pattern may be a randomly selected string by the server 40 or the lock performing unit 14 as a pattern different from the lock pattern set by the student who is the user of the student terminal 10.

On the other hand, the lock performing unit 14 can switch the student terminal 10 from the locked state to the released state when the unlocking time comes. At this time, the lock performing unit 14 may use the above-described lock pattern for unlocking.

Or the lock performing unit 14 may switch the student terminal 10 from the locked state to the released state upon receiving the unlock command from the server 40. [ That is, when the unlocking time is received and stored in advance in the student terminal 10, the lock performing unit 14 can switch the student terminal 10 to the unlocked state at the unlocking time with the lapse of time have.

At this time, the unlock command transmitted from the server 40 to the student terminal 10 may be transmitted to the push notification as in the lock command, or may be transmitted as a message using the SMS or MMS. When the message including the unlock command is transmitted to the student terminal 10 via the SMS or MMS, the use restriction application installed in the student terminal 10 checks the data included in the message to determine whether or not the unlock command is included So that the lock performing unit 14 can switch the student terminal 10 from the locked state to the released state.

At this time, the unlock command can also be transmitted to each student terminal 10 when the teacher terminal 20 requests the server 40 to unlock it.

On the other hand, the unlock command may include information on the lock pattern previously set on the server 40 side for each student, and the use restriction application installed on the student terminal 10 may be included in the lock command or the unlock command, The user can switch the lock state of the student terminal 10 to the unlock state using the lock pattern received by the terminal 10 or display the lock pattern to the user so that the user can directly release the lock state.

On the other hand, if the network connection of the usage restricting application installed in the student terminal 10 is difficult or prohibited, or if the student terminal 10 or the server 40 experiences a temporary error or the like, If the student terminal 10 is still locked even though the lockout time has elapsed or the server 40 has sent an unlock command to the student terminal 10, (40). ≪ / RTI > Alternatively, the lock performing unit 14 may send an unlock request to the server 40 so that the lock can be unlocked exceptionally at the request of the student even before the unlocking time has come.

For this, the lock performing unit 14 may provide a user interface for inputting an unlock request to one side of the lock screen when the student terminal 10 is in a locked state. The server 40 transmits the request to the teacher terminal 20 corresponding to the student and if the student 40 accepts the release of the lock from the teacher terminal 20, The user can release the lock state of the student terminal 10 by resending the lock command to the student terminal 10 again.

Or the student terminal 10 can not directly communicate with the server 40, the lock performing unit 14 transmits an unlock request to the teacher terminal 20 in a message such as SMS or MMS, As shown in FIG. For example, if a student enters an unlock request via a user interface that can enter an unlock request provided on the lock screen of the student terminal 10, the use lock application sends an unlock request and a corresponding student A message including a URL having information as a parameter may be transmitted to the mobile communication number of the teacher terminal 20 via SMS or MMS.

Accordingly, the SMS or MMS message is delivered to the teacher terminal 20, and the teacher can click or touch the URL included in the message to agree to unlock the student terminal 10.

Accordingly, when the server 40 receives from the teacher terminal 20 corresponding to the student terminal 10 requesting to unlock the student terminal 10 a request to access the URL including the student information of the student as a parameter, And transmits an unlock command to the student terminal 10 in an SMS or MMS message.

Accordingly, the student terminal 10 can perform unlocking or display lock pattern information according to the unlock command included in the message. At this time, the unlock command may include lock pattern information as described above.

The present invention may further include an attendance confirmation unit 15 for confirming attendance of the student corresponding to the student terminal 10 according to the embodiment. The attendance confirmation unit 15 confirms whether the student is absent or absent, and notifies the lock execution unit 14 of the confirmation. In this case, the lock performing unit 14 can perform locking only when it is confirmed that the student has attended the school.

At this time, confirmation of attendance or absence may be performed in various ways. If a student who is a user of the student terminal 10 himself / herself selects his / her state as 'absent', he or she is absent. Otherwise, can do.

Or the attendance confirmation unit 15 may be configured such that the location of the student terminal 10 corresponds to the student terminal 10 using a position information collection means included in the student terminal 10, for example, a Global Positioning System (GPS) If the student is found to be within a certain distance from the school's offline address location, the student can be treated as absent and otherwise treated as absent. At this time, the attendance confirmation unit 15 can confirm whether or not the attendance is confirmed at the lock start time or a certain time before the lock start time.

The attendance confirmation unit 15 also receives the absence confirmation request from the student terminal 10 and transmits the absence confirmation request to the teacher terminal 20 corresponding to the student terminal 10 and performs the absence check processing at the teacher terminal 20 The student may be treated as absent.

Furthermore, when it is determined that the position of the student terminal 10 is within a certain distance from the off-line address of the school at or before the lock start time, the lock accepting unit 13 determines whether the lock acceptance , And if the student is confirmed to have accepted the lock, the student may be considered to be present.

In this way, the lock performing unit 14 can transmit the information on the attendance or absence of the student to the server 40 so that the teacher terminal 20 can confirm whether or not each student is attending.

Meanwhile, the student terminal 10 according to the embodiment of the present invention may include the pest blocking portion 16. The pest blocking unit 16 confirms whether or not the student intends to access the pest using the network connecting means installed in the student terminal 10 in a state in which the lock performing unit 14 has unlocked the student terminal 10 To block access to pests.

The pest blocking unit 16 may protect the student from pests by blocking the transmission of the search request or blocking the reception of the search result if the search word input by the student includes a predetermined 'harmful word'.

The harmful substance blocking unit 16 may block the transmission of the access request for the URI if the URI (Uniform Resource Identifier) of the information to be accessed by the student is determined to be harmful information set in advance, Reception can be blocked.

At this time, in determining whether the inputted search word belongs to the 'harmful word' or whether the selected URI corresponds to the 'harmful information', the harmful substance blocking unit 16 sends the user terminal 10, or the information contained in the inputted search word or URI is transmitted to the server 40, and compared with the harmful policy data stored in the server 40, so that the harmfulness can be reviewed .

The pest blocking unit 16 compares the data included in the message transmitted through the SMS or the MMS to the student terminal 10 with harmful words or harmful information included in the harmful policy data and includes harmful words or harmful information If it is determined that the harmful word or the harmful information is included, the sender information of the corresponding message and the harmful message data included in the message can be registered and stored in the server 40. Accordingly, a list of harmful message data registered in the server 40 may be provided to the teacher terminal 20 or may be made available to the parents by the web page.

Meanwhile, the student terminal 10 according to the embodiment of the present invention may include a deletion prevention unit 17. The deletion prevention unit 17 may prohibit the deletion of the usage restricting application by using an API supported by the operating system of the student terminal 10 as a means for preventing the use restricting application from being deleted from the student terminal 10 . For example, if you enable the 'administrator privilege' setting for the restricted use application and the student agrees to set the administrator privilege, then one of the policies set by the administrator privilege will be used, Deletion can be made impossible. Of course, this is an example only, and it is possible to prevent the deletion of the use restriction application by using a method supported by the operating system of the student terminal 10 in which the use restriction application is installed, and if the user's consent is needed, You can ask if you agree.

The deletion prevention unit 17 also continuously transmits a response to the server 40 in response to a request from the server 40 or according to a predetermined schedule so that the server 40 can send the response to the server 40 You can make it possible to confirm that the installed usage restriction application has not been deleted. The server 40 may determine that the use restriction application has been deleted from the student terminal 10 if the response for detection of deletion has not been received from the specific student terminal 10 for a predetermined period or more, ).

In addition, the student terminal 10 senses the occurrence of an emergency, and when the occurrence of an emergency is detected, the current position information of the student terminal 10 is transmitted to the server 40, or the teacher terminal 20 or And an emergency notification unit (not shown) that can be transmitted to the other guardian. At this time, the method of detecting occurrence of an emergency in the student terminal 10 can be performed by detecting whether a preset pattern input (input using a button, a touch panel, an inertial sensor, or the like) occurs, but various other methods can be used .

Alternatively, the emergency notification unit notifies the teacher or the guardian of the location information of the student terminal 10 when an emergency occurs, and makes telephone connection to the mobile communication number of the preset teacher terminal 20 or the guardian's mobile communication number It is possible.

Furthermore, the student terminal 10 according to the embodiment of the present invention may further include a bulletin board providing unit (not shown). The server 40 may divide the small group into small groups so that a separate bulletin board service may be provided for each class, and may register and receive a post from each of the student terminal 10 and the teacher terminal 20 . Then, the collected postings are gathered in small groups and provided to the teacher terminal 20 or the student terminal 10, so that the bulletin board providing unit can provide the students with bulletins related to the class.

Hereinafter, a specific configuration of the server 40 that communicates with the above-described student terminal 10 will be described.

The server (40) includes an information management unit (41). The information management unit 41 receives a request for creating a school account from the administrator terminals 20 and 25, that is, a request for joining a service of a specific school, and stores the school identification information, password, school related information, The information of the requested manager can be input. You can create a school account using the input information. At this time, in order to create an account, it is possible to perform authentication for an administrator individual, for example, cell phone authentication, using information of an individual who has requested to create a school account.

At this time, the school account is created so that at least one manager account corresponding thereto can be created together. Alternatively, the school account and at least one administrator account can be managed in the same single account.

When the school account is created as described above, the information management unit 41 receives a plurality of pieces of manager information that are dependent on the created school account, for example, teacher's personal information and other operator's personal information, and stores the corresponding information in accordance with the school account. At this time, the personal information of the teacher or the operator may include a mobile communication number (telephone number) or an e-mail address of each individual.

Particularly, for each teacher, identification information of a class to be taught by the teacher, for example, information such as 'third grade third class' can be associated and stored.

Also, for each teacher, the teacher's timetable information, for example, the teacher's identification information, such as 2 classes for 1st grade on Monday, 8 classes for 3rd grade on 2nd class on Monday, The schedules may be stored together.

After the information management unit 41 stores the personal information of each teacher, an administrator application installation invitation message or an invitation message to the administrator web page is sent to each teacher terminal 20 using the teacher's mobile communication number or e-mail address . At this time, the invitation message may include link information for accessing the installation page of the manager application or link information for accessing the administrator web page.

Accordingly, the teacher terminal 20 can access the server 40 through the administrator application or the administrator web page by selecting the link information.

Then, the teacher terminal 20 can request creation of a teacher account in order to use the service provided by the server 40. In order to create a teacher account, the information management unit 41 receives a name and a mobile communication number (or an e-mail address) from the teacher terminal 20 requesting creation of a teacher account. Then, a name and a mobile communication number (or an e-mail address) received from the teacher terminal 20 are retrieved from the teacher's personal information of the registered school account in advance, and a specific school account You can create a teacher account as an account that is subordinate to the school account only if it matches the personal information of the teacher registered in.

In addition, the information management unit 41 may receive and store individual student personal information from the teacher terminal 20 or the operator terminal 25 to create a student account that is subordinate to the school account. The student information may also include the name of the student and a mobile communication number or e-mail address. At this time, the respective student information may be grouped into small groups, for example, each class, according to the inputs of the teacher terminal 20 or the operator terminal 25.

When the student terminal 20 or the operator terminal 25 receives the respective student information to be subordinate to the specific school account, the information management unit 41 uses the mobile communication number (or e-mail address) of each student An application installation invitation message can be sent to each student terminal 10 via a text message or e-mail. At this time, the invitation message may include link information for accessing the installation page of the use restriction application.

When the use restriction application is installed in the student terminal 10, the information management unit 41 of the server 40 obtains the name of the student and the mobile communication number from the student terminal 10 accessing the server 40 through the use restriction application (Or e-mail address).

Then, the information management unit 41 performs the personal authentication process for the student corresponding to the inputted information, and then transmits the name and the mobile communication number (or e-mail address) received from the student terminal 10 to the student A student account can be created as an account that is dependent on the school account only if it matches the personal information of the student who is registered in the specific school account by retrieving it from the personal information. At this time, it is possible to perform not only the individual authentication process but also the authentication process of the individual.

In this way, the information management unit 41 stores the information of each operator, teacher, and student operating the terminal use restricting service provided by the server 40 in relation to the school and the school account, the account assigned thereto, and the relationship between the accounts And stores and updates information.

Meanwhile, the server 40 according to the embodiment of the present invention may include a lock setting unit 42. The lock setting unit 42 is set to lock each of the semi- or school-dependent subordinates from the teacher terminal 20 or the operator terminal 25. [ The lock setting can be performed by transmitting to the server 40 information about the lock object, the lock start time, and the lock release time.

The lock target may be an individual, a class, or an entire school, and the lock start time and the lock release time may be set each time or may be set to a schedule (or a timetable) including a plurality of times.

In particular, the timetable itself that is adhered to by the school can be input as information for lock setting. The start and end of the class time can be set as the lock start time and the lock release time in the time table of each class and the lock target can be the student terminals 10 included in the class.

Of course, it is also possible to set a lock in real time at the teacher terminal 20 or the operator terminal 25.

Also, the unlocking time may be set by the time range in which the lock is to be performed, such as after the lock start time is set and after the lock time is set, or after 10 minutes from the lock start time .

In this manner, the server 40 can receive information necessary for performing the lock from the teacher terminal 20 or the operator terminal 25.

The lock command unit 43 provided in the server 40 generates a lock command based on the lock setting information set by the lock setting unit 42 from the teacher terminal 20 or the operator terminal 25 And can transmit it to the student terminal 10 to be locked.

For example, according to the timetable set for a particular class, the start time of the second class is set at 10 o'clock and the end time is set at 10:50. If the class is mathematics, the lock command unit 43 The student terminal 10 of the class can be instructed to set the 10 o'clock angle to the lock start time and 10:50 to the lock release time. That is, lock setting information based on the timetable can be transmitted to each student terminal 10.

At this time, the lock command unit 43 may transmit a lock command including lock setting information related to the lock time to each student terminal 10, and the lock command may be transmitted before the lock start time or with the arrival of the lock start time Lt; / RTI >

The lock command unit 43 can also send a push notification when transmitting the lock command including the above lock setting information to the student terminal 10. [

Alternatively, the lock commander 43 may generate a push notification at the same time as the lock start time or before the elapse of the lock start time, so that the use restriction application is executed according to the push notification at the student terminal 10, When the server 40 accesses the server 40, the lock command generated for the student account of the corresponding student terminal 10 may be transmitted. In this case, if the lock setting is performed in real time, that is, for example, the teacher terminal 20 locks the student terminal 10 of the class student to be locked immediately, the lock command unit 43 locks Command to the student terminal (10). In this case, the student terminal 10 can inquire of the student whether or not the lock is accepted as soon as the lock command is received.

Accordingly, the student terminal 10 can control the student terminal 10 to perform the lock at a predetermined time.

The lock command unit 43 also transmits information about the lock pattern randomly determined for each student terminal 10 to which the lock command is sent together so that the lock performing unit 14 of the student terminal 10 can lock The lock pattern included in the command can be used to perform locking and unlocking operations.

Meanwhile, the server 40 according to the embodiment of the present invention may include a lock confirmation unit 44. [ The lock confirmation unit 44 receives a notification from the student terminal 10 to confirm that the lock has been accepted within a predetermined time from the lock start time. If the lock acceptance notification is not received within a predetermined period of time in the student terminal 10 or the lock rejection is not accepted within a predetermined time by the student terminal 10 and the lock rejection notification is transmitted, the student terminal 10 is in the unlocked state And confirms that the student terminal 10 is in a locked state when a lock acceptance notification is received.

Or the lock confirmation unit 44 may confirm that the student corresponding to the corresponding student terminal 10 is present or absent as the generation of the acceptance signal for the lock.

The server 40 according to an embodiment of the present invention may include a status informing unit 45. [ The status informing unit 45 can provide status information on at least one of the lock status of the student terminal 10 corresponding to the teacher, the attendance status of the teacher, and the installation state of the use restriction application to the teacher terminal 20.

At this time, the subject who receives the current status information for the students in the specific class is sent to the teacher terminal 20 who accesses the server 40 by using the teacher account set as the class teacher at the class, or the teacher in charge of the current class time based on the class time table And a teacher terminal 20 that accesses the server 40 using a teacher account set to the teacher account.

In this case, when the cycle of performing the lock is every class time, the lock of the student terminal 10 is set to be performed at the beginning of each class time, and the current status information of the class students is set to the teacher .

In addition, if the lock cycle is one day, the student terminal 10 is set to be locked at the start of each school shift time, and the current status information of the class students can be provided to the class teacher have.

As described above, the status information may include at least one of the lock status of the student terminal 10, the status of the student terminal 10, and the installation status of the use restriction application. The lock status may be a lock acceptance notification Or whether or not any of the lock acceptance notification and the lock reject notification has been received can be determined. It is also determined whether or not the attendance is determined based on whether or not the reception of the lock acceptance notification received by the lock confirmation unit 44 or the receipt of any of the lock acceptance notification and the lock rejection notification, Or may be determined by combining lock acceptance and position information.

The status informing unit 45 can notify at least one of the location information of the student terminal 10 or the information on whether the student terminal 10 is located within a certain distance from the offline address location of the school from the student terminal 10 So that the status information can be generated.

Or the status informing unit 45 can confirm whether or not the use restriction application is installed in the student terminal 10. If a response is received from the deletion prevention unit 17 of the student terminal 10, When the lock acceptance notification is received, it is confirmed that the use restriction application is installed and the installation state is maintained, and can be guided to the teacher terminal 20.

Meanwhile, the server 40 according to the embodiment of the present invention may include a pest management unit 46. [ The pest management unit 46 stores the harmful policy data necessary for judging whether the information contained in the search word or the URI transmitted from the pest blocking unit 16 is harmful words or harmful information, It is possible to judge the harmfulness to the information contained in the search word or the URI and notify the student terminal 10 again.

Hereinafter, the terminal usage restricting method using the above-described configuration will be described step by step.

FIG. 4 is a flowchart illustrating a method for restricting the use of a terminal according to an embodiment of the present invention. FIG. 5 illustrates an example of a screen provided to a group manager terminal according to a method of restricting use of a terminal according to an embodiment of the present invention Fig.

As shown in FIG. 4, the terminal usage restricting method according to an embodiment of the present invention starts from a step S401 in which a lock command is transmitted from a server 40 to a specific student terminal 10. At this time, the lock command includes information on the lock start time and the release time, or includes information for causing the lock to be performed from immediately after the start, or may include information for performing the lock for a predetermined time from the lock start time. Or lock schedule information may be included so that a plurality of locks are performed.

Accordingly, the student terminal 10 waits until a lock command is received or until a lock start time arrives (S101) (S102). Then, a lock acknowledge message (S106).

At this time, the student terminal 10 may optionally determine whether the student terminal 10 is an object to be excluded before outputting the lock confirmation message according to the embodiment. For example, if the current position is confirmed (S103) and it is confirmed that the current address is within a certain distance from the offline address of the school (S104), a lock confirmation message may be output (S106). If it is determined in step S104 that the position of the student terminal 10 is out of a certain distance from the school, the student terminal 10 can send a absence notification to the server 40 (S105).

Alternatively, after the lock start time arrives, it may be checked whether the corresponding student terminal 10 is already absent, and the lock acknowledgment message may be output only if the absence process is not performed (S106). The absent process may be a case where the student terminal 10 requests the absence confirmation from the teacher terminal 20 or the teacher terminal 20 has absent the student terminal 10 in advance.

The lock confirmation message may include a message to guide that the lock start time comes, and a user interface to inquire whether or not to accept the lock.

Accordingly, if the student terminal 10 has input the intention of accepting the lock, the lock is performed (S109). However, if a pseudo rejection of lock is entered or a pseudo indication of acceptance is not inputted until a certain time has elapsed after the lock confirmation message is displayed, the student terminal 10 notifies the server 40 of the lock rejection notification S108 Can be selectively sent. That is, the lock rejection notification may or may not be sent.

Meanwhile, step S109 in which the lock is performed may be performed by switching the student terminal 10 to the locked state. At this time, the transition to the lock state may be performed using the lock pattern included in the lock command.

At this time, the student terminal 10 can send a lock acceptance notification to the server 40 (S110) if it is confirmed that the acceptance of acceptance of the lock is inputted in the step S107.

Then, the student terminal 10 waits until the lock release time comes (S111) (S112), and then releases the lock (S113). At this time, if a lock pattern is required, the lock pattern received from the server 40 may be used in the lock command.

On the other hand, when the lock acceptance notification is received from the student terminal 10 in response to the lock command provided to the student terminal 10, the server 40 collects whether or not the lock acceptance notification from the student terminal 10 is received for each class, (S402), and may transmit the current status information to the teacher in charge of the class or the class teacher in the class (S403). That is, only the student corresponding to the student terminal 10 receiving the lock acceptance notification may be processed for attendance, or the status information may be created by confirming that the terminal is locked. The student corresponding to the student terminal 10 in which the lock acceptance notification is not received or the lock rejection notification is received may confirm that the terminal is in the released state or process the absence information to create the current state information.

Or step S402, it is possible to collect together the absent notifications that can be transmitted in step S105.

In this case, depending on whether or not the absence notification is received, it is possible to check whether or not the user is present and to confirm whether or not the lock acceptance notification has been received. In this case, it is possible to judge separately whether the entrance and the terminal are locked / unlocked.

That is, the student can confirm that the student is present at the same time the lock acceptance is received and the lock acceptance notification is received in the server 40, or the lock and departure of the terminal can be judged separately .

According to one embodiment of the present invention, as shown in FIG. 5, a list of specific class students is provided in the teacher terminal 20 or the operator terminal 25. In addition to this, whether or not the use restriction application for each student is installed may be displayed as non-installed / installed / deleted. The non-installed state may mean that the personal information of the corresponding student is inputted through the administrator terminals 20 and 25 and stored in the server 40, but a student account corresponding to the corresponding student is not created.

The installation state is a state in which personal information of the student is registered, a corresponding student account is created, and furthermore, a continuous response is effectively received from the student terminal 10. On the other hand, the deletion state may mean a state in which a suspicious application is actually suspected to have been deleted because the student's student account has been validly created but no valid response has been received for a certain period of time or more.

Meanwhile, in the embodiment of the present invention, the presence or absence of each student can be displayed together with the teacher terminal 20 or the operator terminal 25. Whether or not attendance is possible may be determined depending on whether the teacher terminal 20 is selectively inputting or whether the student terminal 10 has transmitted the 'absent notification' in step S105 of FIG. 4 or the student terminal 10 4 in step S110 of FIG.

In the lock column, the lock or unlock status of the student terminal 10 of each student can be displayed. This can be determined depending on whether or not the lock acceptance notification of S110 in FIG. 4 was received from the student terminal 10 by the server 40. FIG.

Further, the teacher terminal 20 can selectively check information on the lock pattern assigned to each student. The teacher terminal 20 can checkably provide the lock pattern to switch the student terminal 10 of the specific student to the released state in a special situation. When the lock pattern of the specific student terminal 10 is confirmed at the teacher terminal 20, the server 40 newly changes the lock pattern for the student terminal 10 to change the lock pattern of the student terminal 10 to the teacher terminal 20 and the student terminal 10.
