Hereinafter, a secure communication method and apparatus according to the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a secure communication apparatus according to an embodiment of the present invention.

A mobile terminal 130_n, a network 150 and a service server 170 with a secure communication device 110 according to the present invention.

Hereinafter, the above constituent elements will be discussed in order.

The secure communication device 110 includes a communication unit 111, an input unit 113, an output unit 115, and a control unit 117.

The communication unit 111 may include one or more modules that enable communication with the network 130 located between the mobile terminal 130_n and the mobile terminal (not shown) or the service server 170. [ For example, the communication unit 111 may include a mobile communication unit, a local communication unit, and a wireless Internet unit that communicate with a mobile station.

The mobile communication unit transmits and receives radio signals to and from at least one of a base station, an external terminal, and a server in a mobile communication network. In this case, the wireless signal may include various types of data depending on a voice call signal, a video call signal, and a character / multimedia message transmission / reception.

The wireless Internet part refers to a module for wireless Internet access. Examples of the wireless Internet part include a wireless LAN (WLAN) (Wi-Fi), a wireless broadband (Wibro), a World Interoperability for Microwave Access (Wimax), a High Speed Downlink Packet Access ) May be used.

The short-range communication module is a module for short-range communication. Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), Zigbee, etc. may be used for short range communication technology.

The input unit 113 receives a signal from the communication unit 111 or a user and transfers the signal to the control unit 115 so that the control unit 115 can perform a secure call function.

The output unit 115 outputs an incoming call screen such as caller information to the first display unit (not shown) of the mobile terminal 130_n when a telephone call is received through the communication unit 111, (Not shown) of the mobile terminal 130_n to receive at least one touch operation or a drag operation from the user (hereinafter referred to as 'operation screen'). The second display unit may be formed integrally with the first display unit and may be formed at either the left end or the right end of the first display unit. That is, the operation screen can be outputted to the left end or the right end of the output screen.

2 is a block diagram for explaining the configuration of the controller 117 according to the present invention in detail.

2, the control unit 117 may include an acceptance processing unit 210, a setting unit 230, a cancellation processing unit 250, and a rejection processing unit 270. [

The acceptance processing unit 210 receives at least one touch operation or drag operation input from the user on the operation screen when a telephone call is received and a touch operation for receiving a telephone previously stored in the storage unit 231 of the setting unit 230 (Hereinafter referred to as " call acceptance combination ") to decide whether or not to receive the call.

The call acceptance combination may be set to a direction of a drag operation with at least one candidate icon displayed on the operation screen as a start point. For example, when a drag operation with two candidate icons as start points is set as a call acceptance combination, a first drag operation corresponding to a first direction, which is the direction of a drag operation with a first icon set as a call acceptance combination, After the input, when the second drag operation corresponding to the second direction, which is the direction of the drag operation whose start point is the second icon set in the call acceptance combination, is input, the telephone can be received. However, if a first drag operation that does not match the first icon or the first direction is input, or a second drag operation that does not match the second icon or the second direction is input, the first drag operation and the second drag Operation can be input.

In addition, the call acceptance combination may be set to an area (icon) to which the start point and the end point of the drag operation input to the plurality of candidate icons displayed on the operation screen belong. For example, when the call acceptance combination is set to two drag operations, after the first drag operation is started with the first start icon set as the call acceptance combination as the start point and the second end icon as the end point, When the second drag operation that sets the second start icon as the start point and the second end icon as the end point is inputted, the user can receive the call. However, if a first drag operation that does not match the first start icon or the first end icon is input, or a second drag operation that does not match the second start icon or the second end icon is input, An operation and a second drag operation can be inputted.

Further, the call acceptance combination may be set to a touch operation combination input to at least one candidate icon among a plurality of candidate icons displayed on the operation screen. For example, when two candidate icons are selected, when a first touch operation is inputted to a first icon set as a call acceptance combination and then a second touch operation is inputted to a second icon set as a call acceptance combination, If either the first icon or the second icon does not match, the first touch operation and the second touch operation can be input from the user again.

These icons can be implemented as individual identifiers such as characters (animals such as cattle, pigs), alphabets, symbols (#, $, etc.), numbers, shapes (triangles, squares, etc.) A plurality of icons may be arranged. In addition, the arrangement form of these icons can be rearranged and displayed every predetermined period.

Hereinafter, a description will be given on the assumption that two drag operations or two touch operations are performed in accordance with the call admission combination, but this is for the sake of easy explanation and does not limit the number of times of drag operation or touch operation.

The setting unit 230 may include a storage unit 231, a setting screen display unit 233, and an emergency contact setting unit 235.

The storage unit 231 stores a call acceptance combination, an arrangement cycle, an effective frequency and an effective time set by the user.

The call acceptance combination may be set to a combination of touch operations input to at least one of the candidate icons selected from the at least one candidate icon displayed on the incoming call screen as described above.

The arrangement period refers to a period in which the icons displayed on the incoming screen to identify the candidate areas are rearranged. The arrangement order of the icons can be changed when the time passes by the array period. For example, if the icon set in the call acceptance combination is 'A' located in the area A1 and 'B' located in the area B1, the phone can be initially received by inputting the touch operation to the area A1 and area B1, After the 'A' icon is rearranged to the area A2 and the 'B' icon is rearranged to the area B2, the touch operation must be inputted to the area A2 and the area B2 so that the telephone can be received. According to the arrangement period, the arrangement of the icons can be changed to further increase the call security effect.

The validity number means the number of times set to receive a valid call acceptance combination. If an operation that matches the call acceptance combination is not input so as to exceed the valid number, the call rejection processing unit 270 may reject the call. The effective number of times may be set in a range from 3 times to 5 times.

The valid time means a time set for receiving a valid touch operation. If the second operation is not inputted during the valid time after the first operation, the reject processing unit 270 can reject the call. This valid time is meaningful only when the call acceptance combination is composed of a plurality of operations. If the call acceptance combination is set as a single operation, the validity time may not be stored in the storage unit. In the case of inputting by n touch operations, the rejection processing unit 270 can reject the call if the time between the m-th touch operation and the (m + 1) -th touch operation elapses. Where m is a natural number equal to or greater than 1 (n-1).

This valid time is preferably between 1 second and 3 seconds. If it is set shorter than 1 second, unintentional call rejection may occur. If it is set longer than 3 seconds, it may take a long time for call rejection.

The setting screen display unit 233 displays a screen for setting a call acceptance combination on the display of the mobile terminal 130_n and stores the call acceptance combination input from the user on the setting screen in the storage unit 231. [ The above-described call acceptance combination can be set to at least one drag operation or touch operation input to at least one candidate icon displayed on the operation screen as described above.

In addition, the call acceptance combination may be set to the same for all contacts stored in the address book of the terminal, or may be set for individual contacts or individual contact groups.

Here, an individual contact refers to each of the numbers stored in the address book (eg, Gil Suh, Young-Hee, etc.), and an individual contact group means a group of contacts (family, friend, etc.)

When setting the call acceptance combination for each individual contact or individual contact group, the storage unit 231 may store the contact or contact group and the corresponding call acceptance combination information together.

The emergency contact setting unit 235 stores emergency contact information set in advance so that everyone can receive the telephone, which will be described in detail below.

The release processing unit 250 may include an emergency contact execution unit 251 and a switching unit 253. [

The emergency call execution unit 251 cancels the secure call function when the call is received from the emergency contact stored in the emergency contact setting unit 235 or displays the normal call incoming screen (normal call mode) .

The secure call release mode refers to a mode that allows the user to receive a call when an operation is input by the user regardless of the position of the touch operation, the direction of the drag operation, or the end point of the drag operation.

In addition, the general call mode is a mode in which a call connection icon is dragged in a direction set by a manufacturer to receive a call. In general, a method of receiving a call by dragging a call connection icon in the direction of a call end icon may be used.

In addition, the information on the selected mode, including the secure call release mode and the general call mode, and the corresponding emergency contact information may be stored together in the emergency contact setting unit 235. [

The switching unit 253 stores a normal call conversation password preset by the user, and switches the call reception mode to the normal call mode when the normal call conversation password is input through the remote connection.

The rejection processing unit 270 functions to reject a call that the user does not desire.

If the operation corresponding to the combination of the call acceptance is not input during the effective number of times stored in the low level portion 231, the call can be rejected.

Also, if the (n + 1) th operation is not input during the valid period of time stored in the storage unit 231 after the n-th operation is input, the call can be rejected.

This valid time is preferably between 1 and 3 seconds. If it is set shorter than 1 second, unintentional call rejection may occur. If it is set longer than 3 seconds, it may take a long time for call rejection. There is a bar.

Further, when a drag operation in the vertical direction with the first point or the second point located at the edge area of the operation screen as the start point is input, the call can be rejected. For example, the drag operation may be performed by inputting a drag operation in the vertical direction while touching an edge region of the screen, that is, a portion located at the outer edge of the physical screen region or one point of the bezel portion (upper end or lower end of the operation screen) It says.

In addition, when a horizontally dragging operation in which the call connection icon is the starting point is inputted in the incoming call screen, the call can be rejected.

Hereinafter, a drag operation for rejecting a call such as a drag operation in the horizontal direction with the call connection icon as the start point, a drag operation in the vertical direction with the upper edge region of the operation screen or the lower edge region as the start point is called a call rejection operation .

In addition, when a call rejection operation is input and the call reception is to be rejected, the rejection message can be transmitted from the operation screen.

3 is a flowchart for explaining an embodiment of a method of setting a call acceptance combination according to the present invention.

Referring to FIG. 3, in the setting method according to the present invention, a contact or a contact group for setting a call acceptance combination by a user is selected (S310) and individual setting is started (S320). Here, a contact (eg, Ji-soo, Young-hee, etc.) means an individual number stored in the address book. A contact group (family, friend, co-worker, etc.) means a group of contacts grouped on a predetermined basis. In addition, when the same call acceptance combination is set for all contacts or contact groups, step S310 may be omitted and all settings may be selected in step S320.

When the call acceptance combination setting is started, the setting screen display unit 233 outputs a call acceptance combination setting screen including the call connection icon to the display device of the mobile terminal 170_n (S330). At this time, at least one candidate icon can be displayed together.

(Touch operation or drag operation) for setting a call acceptance combination from the user (S340), and stores the operation in the storage unit 231 as a call acceptance combination (S370).

And may be re-entered a plurality of times to confirm the call acceptance combination. In this case, the operation is input again from the user after step S340 (S350). After comparing the operation received in step S340 and the operation received in step S350 (S360) The received operation is stored in the call acceptance combination (S370), and if not, the operation in step S350 can be re-entered.

If the individual setting is selected in step S320, the contact or the contact group selected in step S310 may be stored together when the call acceptance combination is stored in the storage unit in step S370.

In addition, the service acceptance combination and the corresponding contact or contact group can be stored in the service server 170 in preparation for the failure or loss of the mobile terminal.

4 is a flowchart illustrating an emergency contact setting method according to the present invention.

It is desirable to set a method for allowing all users to receive a telephone call when a mobile terminal such as a smart phone is lost.

As shown in the figure, an emergency contact for contacting a lost mobile terminal when the mobile terminal is lost can be selected or input in the address book (S410). At this time, one or more emergency contacts can be set. Thereafter, the call reception mode of the call received from the emergency contact is selected (S420). The call mode can be selected from the normal call mode and the secure call release mode. When selecting the normal call mode, a general call forwarding screen displaying a call connection icon and a call ending icon is displayed, and a call connection icon can be dragged horizontally to receive a call. Also, when the secure call release mode is selected, the call can be received when an operation is input by the user irrespective of the position of the touch operation, the direction of the drag operation, or the end point of the drag operation. When the emergency contact and the reception mode are input by the user, the emergency contact and the reception mode corresponding to the emergency contact can be stored together in the emergency communication setting unit 235 (S430).

FIG. 5 is a flowchart for explaining a secure call method according to the present invention, FIG. 5A is a flowchart for explaining a state before a secure call function is executed, and FIG. 5B is a flowchart for explaining after a secure call function is executed .

As shown in FIG. 5A, when the call signal is received, the call destination number is collated with the emergency contact registered in the emergency contact setting section 237 (S510). If it is determined that the called number matches the registered emergency call number, the emergency call execution unit 251 of the release processing unit 250 checks whether the call reception mode registered in the emergency call execution unit 251 is the normal call mode or the secure call release mode (S511) (S521). If the mode is the secure call release mode, the secure call function is canceled (S512), and the start point of the drag operation or the direction of the drag operation When an operation is input from the user regardless of the end point of the drag operation or the position of the touch operation (S513), the call is connected to receive the telephone (S570). If the destination number does not match the emergency number registered in advance, the storage unit 231 of the setting unit 230 determines whether the secure call function is the entire setting (S515). If the destination number is not the entire setting, (S520). When the number is not set individually, a general call screen is displayed (S521), and a call can be received. If the secure call function is set for the entire contact, or if the called number belongs to the individually set contact or contact group, the secure processing function is executed in the acceptance processing unit 213 (S525).

The operation after the secure communication function is executed is as shown in FIG. 5B.

Referring to FIG. 5B, when the secure call function is executed, an operation screen including an incoming call screen including a call connection icon and at least one candidate icon is output (S530). At this time, at least one icon may be further output on the incoming call screen. Thereafter, the first operation is input from the user (S535). The first operation may be an operation for receiving a call, or an operation for rejecting a call. It is confirmed whether the first operation is a call rejection operation (S540). If the first operation is a call rejection operation, the call is rejected (S541). If no operation is input during the valid period of time, the reject processing unit 270 checks whether the valid period has elapsed until the second operation is input (S545) (S541). If the second operation is inputted before the expiration time has elapsed (S550), it is checked whether all the operations set as the call acceptance combination are completed (S555). If not, the operations of S545 and S550 may be repeated. If all the operations set in the call acceptance combination are inputted, the received operations are compared with the call acceptance combinations stored in the storage unit 231 (S560). If they do not match, the effective number stored in the storage unit 231 is exceeded (S565). If the answer is YES, the rejection processing unit 270 rejects the call (S541). The rejection count has not been exceeded and the call can be input again from the first operation in step S535. If the input operation and the call acceptance combination stored in the storage unit 231 coincide with each other, the call is received and the call is connected (S570).

6 is a diagram for explaining the call admission combination setting screen according to the present invention in more detail.

Referring to FIG. 6, the setting screen according to the present invention includes an incoming call screen DP_1 in which an operation button BT_n is displayed and an operation screen DP_2 including at least one candidate icon CA. Although the drawing shows that the operation screen DP_2 is located on the right side of the incoming screen DP_1, it can be formed on the left side of the incoming screen DP_1 as described above.

The candidate icon CA may be implemented in various forms such as an alphabet icon, a character icon, a numeric icon, and a graphic icon, and the form is not limited thereto as long as the candidate icon CA can be distinguished from each other.

In addition, although seven candidate icons CA are shown in the figure, it is obvious that the number can be changed.

The operation button BT may include a button BT_1 for retrying the operation combination input and an confirmation button BT_2 for allowing the storage unit 231 to store the drag operation combination input.

The user can input and select the operation on the candidate icons CA and then select the OK button BT_2 and store the received combination in the call acceptance combination.

When the number of the candidate icons CA is n, and the number of the call acceptance combinations is set to the start icon and direction of the dragging operation of m times, the number of candidate icons CA is (2n) m, The number of cases is (nP2) m. In addition, the number of cases in which the call acceptance combination is set to the position (touch icon) of m touch operations is nm.

When the number of candidate icons is seven and the call acceptance combination is made by two operations, the number is set to 196 when the drag operation is set to the start icon and direction, the start icon is set to 1,764 when the drag operation is set to the start icon and the end icon, If it is set to the touch operation position, the security effect can be sufficiently secured by 49.

FIG. 7A illustrates a case where a call acceptance combination is set to a start point and a direction of two drag operations, FIG. 7B illustrates a case where a call acceptance combination Is set as a start point and an end point of two drag operations, and Fig. 7C shows a case where the call acceptance combination is set by two touch operations.
