However, the present invention is not limited to the embodiments disclosed below, and can be embodied in various different forms. This embodiment is provided only for the purpose of completing the disclosure of the present invention and informing the person skilled in the art of the present invention the full scope of the invention. The invention is only defined by the scope of the claims.

  In describing the embodiments of the present invention, detailed descriptions of well-known functions and configurations are omitted when it is determined that the gist of the present invention is unclear. The terms described later are terms defined in consideration of the functions in the embodiments of the present invention, and this may vary depending on the intention or custom of the user or operator. Therefore, the definition should be judged on the basis of the technical idea throughout this specification.

  FIG. 1 is a diagram illustrating a configuration of a terminal control apparatus using a notification message according to an embodiment of the present invention. 1 may include a detection unit 110, an analysis unit 120, and a control unit 130. However, since the terminal control apparatus 100 of FIG. 1 is only one embodiment of the present invention, the idea of the present invention is not limited to FIG. The terminal control device 100 may exist separately from the user terminal 10 to be controlled by the terminal control device 100, but may preferably be embodied in the user terminal 10 as a part of the user terminal 10. . In the following, for the sake of convenience, description will be made on the assumption that the terminal control device 100 is embodied in the user terminal 10.

  The user terminal 10 of the present embodiment is a popular portable electronic device in which a mobile operating system is installed. For example, a smartphone can be mentioned. In the following description, the mobile operating system of the user terminal 10 is assumed to be an Android. However, this is for convenience of explanation and is not intended to limit the idea of the present invention.

  The user terminal 10 can be configured to receive a notification message output request and output a notification message based on the notification message output request. The notification message is a message output through the display of the user terminal 10 in order to notify the user of certain contents, and the predetermined information is sent to the user regardless of whether or not the specific application is being executed. The reason for transmitting is as described above. The output request for the notification message can be generally received from outside the user terminal 10 through a packet-based message, but can be generated within the user terminal 10.

  The detection unit 110 can detect an output request for a notification message received by the user terminal 10. When registering “BroadcastReceiver”, one of the Android components, in the Android notification system (notification system), the detection unit 110 receives a notification message output request and transmits the content of the notification message output request to the analysis unit 120 can do.

  The analysis unit 120 can analyze the output request for the notification message transmitted from the detection unit 110 and determine whether the preset character string is included in the output request for the notification message. The output request for the notification message can include the content of the notification message output by the user terminal 10, and specifically can include a message title, a message body, an icon output together with the message, and the like.

  The control unit 130 can control the user terminal 10 to perform a preset operation based on the determination result of the analysis unit 120. A detailed example of the preset operation performed by the user terminal 10 will be described later. The terminal control device 100 including the control unit 130, the detection unit 110, and the analysis unit 120 can be implemented by a calculation device called a general microprocessor.

  Hereinafter, the operation of the terminal control apparatus 100 according to an embodiment of the present invention will be described in detail with reference to FIG.

  First, the user terminal 10 can receive a notification message output request from the outside. The output request for the notification message can be transmitted from another user terminal connected to the user terminal 10 via a network or a computer such as a server. The network may be a wired or wireless network, and when connected by a wireless network, preferably, a wireless network such as Wi-Fi, 3G, 4G, LTE (registered trademark) (long-term evolution) is used. Can be done. The notification message output request may be transmitted using various applications that can output the notification message. The application may be an online instant messenger (online instant) such as Kakaotalk or Line. or a social network service (SNS) application such as Facebook (registered trademark) or Twitter (registered trademark).

  The output request of the notification message transmitted to the user terminal 10 can be detected by the detection unit 110 of the terminal control apparatus 100 and the content can be transmitted to the analysis unit 120. The analysis unit 120 can analyze the content of the notification message output request and determine whether or not a preset character string exists in the content. The determination process of the analysis unit 120 can be performed using a regular expression, and the determination process using the regular expression is obvious to those skilled in the art, and thus further detailed description is omitted. .

  Based on the determination result made by the analysis unit 120, the control unit 130 can control the user terminal 10 to perform a specific operation. Through the process described so far, the user of the user terminal 10 can set the characters already set in the user terminal 10 from another user terminal or server through one of various applications that can output a notification message. By transmitting the output request for the notification message including the queue, the user terminal 10 can be easily controlled at a remote place. For example, the user of the user terminal 10 controls the user terminal 10 to perform an operation corresponding to the character string by transmitting a cacao talk message including a specific character string to the user terminal 10 through the user terminal of an acquaintance. can do. As another example, when a user leaves a Facebook message including a specific character string in the user's own account through an account of an acquaintance at a remote place, the notification message including the character string is displayed on the user terminal 10. Thus, the user terminal 10 can be controlled to perform an operation corresponding to the character string.

  Thus, according to an embodiment of the present invention, a user can easily control his / her user terminal 10 at a remote place through any application having a function of outputting a notification message. However, when the user's contact information is exposed, the user terminal 10 can be controlled by another person at a remote place regardless of the user's intention. It can be set or changed to a character string that cannot be easily guessed by others. Alternatively, the user terminal 10 may be set to perform an operation corresponding to the preset character string only when a specific password is included in the notification message output request together with the preset character string. it can.

  Hereinafter, functions that can be performed by the user terminal 10 under the control of the control unit 130 will be described in detail with reference to examples. As an example, the control unit 130 may perform a lost device control function for controlling the user terminal 10 to be locked when a preset character string is included in the notification message output request.

  A portable electrical device such as a smartphone may store personal information of a user or data for personal use. Accordingly, a user who has lost a portable electronic device may desire to set the lost device in a locked state in order to prevent information leakage by the finder.

  FIG. 2A is a diagram for explaining a conventional lost device control function. Referring to FIG. 2a, when trying to set a lost device in a locked state using SMS (Short Message Service), a specific message and password are sent to the lost device by SMS to enter the locked state for the lost device. It can be seen that setting is possible. However, in the case of the method through SMS, as shown in FIG. 2a, there is a problem that the password for releasing the lock state is easily exposed, and reception of the SMS is excluded according to the priority order.

  Examples of other conventional lost device control methods include a method using an Android push notification through GCM (Google Cloud Messaging). However, the method using GCM also has a problem that the infrastructure construction cost increases. In order to solve such a problem of the prior art, a lost device control function according to an embodiment of the present invention can be used.

  According to the lost device control function, the control unit 130 may cause the user terminal 10 to be locked when the analysis unit 120 determines that the preset character string is included in the notification message output request. Can be controlled. In addition, the control unit 130 controls the lock state to be released when the password included in the output request for the notification message is input to the user terminal 10 through the preset method. be able to. When the contact information is included in the notification message output request together with the already set character string, the control unit 130 controls to notify that the user terminal 10 is set to the contact state. can do.

  FIG. 2b is a diagram for explaining a device control function of a terminal control apparatus using a notification message according to an embodiment of the present invention. Referring to FIG. 2 b, a user who has lost the user terminal 10 can use his user terminal lost from the other person's terminal 11 through an application that can output a notification message (cacao talk according to the example of FIG. 2 b). A packet-based text message including a character string set to 10, a password, and a contact for replying can be transmitted. Referring to FIG. 2b, the character string “#lock” in the message input field is a preset character string for setting to the locked state, the number 1234 is a password for releasing the locked state, A telephone number of 010-0000-0000 corresponds to a contact for reply. Thus, when the input message, that is, the output request for the notification message is transmitted to the user terminal 10, the user terminal 10 can be locked by the character string “#lock”. It is also possible to notify the contact number of 010-0000-0000 that the lock has been established. The lock state can be released by inputting the transmitted password 1234 to the user terminal 10, and such input can be performed on the display of the user terminal 10 by a touch screen function, for example. This can be done by sequentially pressing the areas corresponding to 1, 2, 3, 4 on the output keypad. Even when the lock state is released, the user terminal 10 can notify the contact that the lock state has been released.

  At this time, if the password is exposed through a notification message output on the display of the user terminal 10, the purpose of setting to the locked state cannot be achieved. Therefore, when the user terminal 10 outputs the notification message, the control unit 130 can control to output only the part excluding the password, or control the output of the notification message itself. You can also Thereby, as shown in FIG. 2b, exposure due to the output of the notification message can be prevented.

  Through the lost device control function according to the embodiment of the present invention as described above, the user of the lost user terminal 10 can easily use his / her user terminal 10 through the corresponding application if the application has a function of outputting a notification message. By setting the lock state, personal information leakage can be prevented. In addition, the lost device control function according to the embodiment of the present invention provides a function for preventing the password from being exposed, so that a higher level of security is achieved in setting the lost user terminal 10 to the locked state. can do.

  Hereinafter, embodiments relating to other functions that can be performed by the user terminal 10 under the control of the control unit 130 will be described in detail. More specifically, the control unit 130 checks the notification message in order to control the user terminal 10 not to output the notification message when the preset character string is included in the notification message output request. Can carry out the function. If the analysis unit 120 determines that URL (uniform resource locator) information is included in the notification message output request, the control unit 130 checks whether the URL of the URL is malignant, A URL check function for controlling to output the result can be performed.

  Recently, there are many cases where unsolicited advertisements or notifications are made through notification messages of mobile operating systems. Accordingly, there is a situation in which a user of a portable electronic device in which a mobile operating system is installed should perform a troublesome action of deleting such unnecessary notification messages one by one. Also, due to the many unnecessary notification messages, important notification messages may be missed. In the following contents, the present embodiment described in detail can provide a solution for such a problem.

  FIG. 3 is a diagram illustrating a notification message checking function of a terminal control apparatus using a notification message according to an embodiment of the present invention. Referring to FIG. 3, in the case of an advertising message, which is a typical type of message that the user is likely not to receive, terms related to shopping such as “discount”, “sale”, “coupon”, etc. It can be seen that is often included. As described above, the control unit 130 outputs a notification message based on one or more preset character strings defined with reference to a character string mainly included in a type of message that the user does not want to receive. Control may be performed so that the user terminal 10 does not output a notification message corresponding to the output request for the notification message when the request includes more than a predetermined number of character strings among the predetermined character strings. it can. The preset number can be 1, but a larger natural number can also be used. In addition, the preset character string can be changed according to the needs of the user. Through such a notification message inspection function, the user can block unwanted notification messages and can always effectively check only necessary messages, so that convenience in using the terminal can be improved.

  FIG. 4 is a diagram illustrating a URL checking function of the terminal control apparatus using a notification message according to an embodiment of the present invention. Referring to FIG. 4, it can be seen that URL information pointing to a specific web page may be included in the notification message. Such a URL may include a malicious URL that may cause the user terminal 10 to be damaged by the malicious code when connecting to a web page corresponding to the URL. Therefore, in this embodiment, when URL information is included in the output request for the notification message, the control unit 130 controls the user terminal 10 to check whether the URL is malignant and output the result of the check. be able to. Such inspection and output can be performed simultaneously with the arrival of the message, but can be performed when the user tries to connect to the web page corresponding to the URL. The form of the test result output may be, for example, a form of warning message output through the display of the user terminal 10. By such a URL inspection function, the user can prevent the user terminal 10 from being damaged by the malicious code in advance.

  On the other hand, when different notification messages are output several times, the output state of the notification message output first may be canceled by the notification message output later. At this time, the user may not be able to confirm the previously output notification message. If the previously output notification message is an important message, a situation in which the user is troubled may occur. Accordingly, when the notification message output request includes important contents, the control unit 130 performs control so that the user terminal 10 continues to hold the state of outputting the notification message corresponding to the notification message output request. be able to. Whether or not important contents are included can be determined based on whether or not a preset character string is included in the output request for the notification message. With such a function, it is possible to prevent a disadvantage that may occur when the user cannot confirm an important notification message.

  FIG. 5 is a diagram illustrating a procedure of a terminal control method using a notification message according to an embodiment of the present invention. However, since the terminal control method of FIG. 5 is only one embodiment of the present invention, the idea of the present invention is not limitedly interpreted by FIG.
