Say this is possible terminal.

These days, wireless terminals have become a necessity for individuals and are used in homes, workplaces, and many public places. As a result, it is easier for others to access internal information of the wireless communication terminal.

Various information stored in the wireless communication terminal such as a transmission / reception message, a phone book, a memo, and the like may include contents related to personal privacy or difficult to know by others, contact information, financial relations, or important information on a contract. . In order to protect such information from access by others, various data protection technologies have been developed to prevent exposure to the outside.

If you try to access the data or menu for which the lock function is set by setting the lock function for individual data or collectively setting the lock function for the entire menu (eg phone book), the preset password (password) is set. For example, technology that allows access only when input is received, or technology that hides individual data or menus from the outside.

However, in the case of the conventional data protection technology that protects collectively or for each data as described above, in order to set the protection mode, the user must individually access and set and release each menu or each data to be protected. In order to access the data to be protected, there was an inconvenience in that the user inputs a password one by one.

In addition, the prior art has a problem of causing inconvenience to the user by locking the data that do not need to be protected in the case of protecting the data in a batch.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following exemplary embodiment, a case in which a phone number is used as an identifier for identifying the data protection mode in the wireless communication terminal will be described as an example. That is, data protection is collectively performed on various data related to the telephone number (identifier) set as the operation target of the data protection mode, for example, a message received from the telephone number, registration information on the telephone book for the telephone number. It is possible to set and release modes. In addition, in the following embodiment, the phone number registration information and the reception message on the phone book are described as an example of various data related to the phone number set as an operation target of the data protection mode.

1 is a configuration diagram of an embodiment of a wireless communication terminal having a data protection function using forged data according to the present invention.

As shown in FIG. 1, the wireless communication terminal having a data protection function using forged data according to the present invention includes a wireless transmission / reception unit 11 for transmitting / receiving a wireless signal with an external device through a wireless communication network, and each telephone number. The phonebook that stores the registration information (e.g. name, phone number, title) for the message, send / receive message (e.g. short message / multimedia message), data protection mode release password, and the phone number set as the data protection mode destination. Storage unit 12 for storing forged data (eg, forged message content, forged phone number) for each data, various signals related to data protection mode setting from the user, data protection mode release password, forged data, etc. Input unit (keypad) 13 for receiving the input, the display unit for displaying a screen for counterfeit data or actual data, etc. under the control of the control unit 15 According to various signals related to data protection mode setting received through the LCD 14 and the input unit (keypad) 13, a data protection mode (a plurality of data protection modes exist) for a specific telephone number is set. In response to detecting an attempt to access a phone number and various data related thereto (for example, an incoming message and phone number registration information), an authentication process according to a preset data protection mode release method is performed, and as a result, the input unit (keypad) 13 When the preset data protection mode release password is input (or specified condition is met), the actual data is output through the display unit (LCD) 14, and when no input is received (or specific condition is not met). The control unit 15 outputs the stored forged data through the display unit 14 and the wireless transmission / reception unit 11 under the control of the control unit 15. Converts the received signal into voice and outputs it to the voice output unit (speaker) 17, converts the voice received from the voice input unit (microphone) 18 into a signal and transmits it to the control unit 15 to transmit and receive the radio transmission and reception unit 11 A codec 16 for transmitting through the voice, a voice output unit 17 for outputting the voice received from the codec 16, and receives a voice to the codec 16 And a voice input unit (microphone) 18 for transmission.

At this time, in the present invention, the control unit 15 controls the overall operation of the wireless communication terminal, and at the same time, a data protection function using forged data according to the present invention, that is, a data protection mode operation function (data protection mode setting and release function) To provide. Here, the forgery data is a preset data for protecting specific data to be protected, for example, a received message and phone number registration information (eg, name, phone number, and title) stored in the phone book from access by unauthorized persons. When the authentication process is performed according to the authentication method (e.g., specific key input method or password input method), it means data that the user has already saved to show to others when it fails. That is, for the purpose of protecting the contents of the received message, the contents of the fake message may be stored, and in the case of protecting the phone number registration information, the forged telephone number, the name of the fake name, the title of the fake, etc. may be stored in advance. The counterfeit data may be data input from the user through the input unit (keypad) 13 or may be random (randomly) selected data among various data stored in the existing storage unit 12.

Looking at the data protection mode operation function in more detail as follows.

The control unit 15 is associated with the telephone number such as a message, telephone number registration information, etc. for a specific telephone number according to various signals related to data protection mode setting received through the input unit (keypad) 13. The data protection mode selected by the user among a plurality of data protection modes is also set for various data. The data protection mode includes a plurality of detailed data protection modes, that is, a telephone number forgery mode (outputs a fake telephone number), a message forgery mode (outputs a content of a fake message), and the control unit 15 includes details. You can set the data protection mode individually or in duplicate. At this time, the control unit 15 receives the data protection mode release password and forged data through the input unit (keypad) 13 and stores it in the storage unit 12, and the data through the input unit (keypad) 13 You are selected to release the protection mode. Here, the data protection mode release method, for example, in response to a specific key is input in the state of outputting forged data, or a method of outputting the actual data, or outputting a password input window according to the input of a matching password Various applications are possible, such as a method of outputting forged data as the actual data is output and not received, and according to the data protection mode release method, the data protection mode release password may also be implemented in various forms such as a specific key input signal and a password. Can be. The data protection mode setting as described above may be implemented through a specific sub-menu or main menu related to phonebook protection.

Then, the controller 15 detects an attempt to access a phone number set as an operation target of the data protection mode and various data related thereto, for example, registration information on a phone book for the phone number, or the As various request signals for a message (for example, a short / multimedia message) received from a telephone number are received through the input unit (keypad) 13, an authentication process according to a preset data protection mode release method is performed. For example, in the case of a specific key input release method, once the forged data is output through the display unit (LCD) 14, a specific key (eg, # 124 #) preset as a data protection mode release password is received. Therefore, the actual data is output. As another example, in the case of a password input release method, first output a password input window through the display unit (LCD) 14 to output actual data according to a preset password as a data protection mode release password, and input an incorrect password. Upon receipt (or even if there is no key input within a certain time), counterfeit data is output. In this case, when the actual data is output, the data protection mode for the actual data is temporarily released (not completely released) and the corresponding menu is terminated (for example, the telephone directory is terminated). Resume data protection mode operation for the server.

On the other hand, the control unit 15 does not output the actual data or the counterfeit data by performing an authentication process according to a preset data protection mode releasing method in response to detecting access to specific data that is an operation target of the data protection mode. As soon as this is satisfied, the data protection mode can be automatically released and reset. For example, when entering a preset time zone, the data protection mode is temporarily released (or reset), and the data protection mode is reset (or temporarily released) when it is outside the time zone, or the outdoor / indoor / home / car The data protection mode may be temporarily released or reset as a specific mode is entered in various wireless communication terminal operation modes such as a conference / meeting mode, and then may be controlled to be reset or temporarily released when the operation mode is exited.

In addition, the controller 15 temporarily releases the data protection mode according to various data protection mode release requests. The data protection mode releasing method includes a specific key input releasing method and a password input releasing method for temporarily releasing the data protection mode, and a data protection mode for a predetermined time (for example, from 9 am to 5 pm). The time setting release method for releasing the data, and when the specific profile is selected, that is, enter the specific operation mode (eg, outdoor / indoor / home / car / meeting mode) of the wireless communication terminal to release the data protection mode. Profile release method and the like. In addition, the controller 15 may completely release the data protection mode according to an input from the user.

The data protection mode operation function as described above will be described later in more detail with reference to FIGS. 2 to 7.

On the other hand, the storage unit 12 stores the operation program and the system program of the control unit 15, the operation program and the system program is stored in the normal ROM (ROM) area and can be erased as necessary. The storage unit 12 also includes a RAM for temporarily storing data generated during execution of various operation programs. In addition, the storage unit 12 is a phone book that stores registration information (eg, name, phone number, title) for each phone number, transmission / reception message (eg short / multimedia message), data protection mode release It stores the password (or specific condition for canceling data protection mode), and forged data (eg forged message contents, forged phone number) for each data related to the phone number set as the data protection mode target. In addition, the storage unit 12 stores a program for providing a user with an interface related to setting and releasing the data protection mode.

The input unit 13 includes a plurality of numeric keys (letter keys), menu keys, and function keys for performing various functions, and outputs key data to the controller 15 according to external operations. In addition, the input unit 13 may provide various signals related to data protection mode setting from the user, that is, a data protection mode setting request signal, a data protection mode operation target phone number input (selection) signal (hereinafter referred to as a phone number input signal), It is used to receive a detailed data protection mode selection signal, a data protection mode release method selection signal, a data protection mode release password (or a specific condition for the release of the data protection mode), and forged data.

The display unit 14 is a display device such as a liquid crystal display (LCD). The display unit 14 displays the state of the wireless communication terminal, the progress of the program, and the like under the control of the control unit 15. That is, the overall state of the wireless communication terminal and the contents received are displayed. In addition, the display unit 14 outputs an interface related to setting and releasing the data protection mode under the control of the controller 15, and outputs the interface to the storage unit 12 according to a result of performing an authentication process according to a preset data protection mode releasing method. Outputs the previously stored forged data (eg forged message content) or the actual data (eg actual message content).

2 is a flowchart illustrating a method for setting a data protection mode in a wireless communication terminal according to the present invention. The data protection mode may be implemented to be set through a menu related to data protection mode setting, for example, an interface of a main menu of a wireless communication terminal or a specific submenu related to protection of a phone book.

First, the control unit 15 receives a data protection mode setting request signal through the input unit (keypad) 13, outputs an interface for setting the data protection mode, and receives a specific telephone number as the data protection mode operation target ( 201). The phone number is directly input by the user through the input unit (keypad) 13 or selected through a phone book search.

Subsequently, the controller 15 determines whether the detailed data protection mode of the plurality of data protection modes is selected according to the input of the detailed data protection mode selection signal through the input unit (keypad) 13 ( 202). In this example, a telephone number forgery mode for forging a telephone number displayed in a phone book, a transmission / reception message, and the like, and a message forgery mode for forging the contents of a transmission / reception message (for example, the content of a short message / multimedia message) are given as an example. Let's explain.

As a result of the detailed data protection mode determination 202, in the case of the telephone number forged mode, a fake telephone number and a fake title are input as the fake data (203). For example, "010-123-2233" may be input as a counterfeit telephone number, and "Hong Gil-dong-workplace boss" may be input as a counterfeit title.

In addition, the detailed data protection mode determination result 202, in the case of the message forgery mode, receives the contents of the forgery message as the forgery data (204). For example, if you want to falsify a short message, text content such as "Be faithful to your job." If you want to falsify a multimedia message, multimedia content (eg text, photo, music files) can be used as the fake message content. Can be chosen. In the detailed data protection mode as described above, one detailed data protection mode may be set, but two or more detailed data protection modes may be set repeatedly. A more detailed description thereof will be described with reference to FIGS. 4 to 7.

Thereafter, the controller 15 receives a data protection mode release method selection signal through an input unit (keypad) 15 to determine which data protection mode release method is selected from among the plurality of data protection mode release methods. Determine (205). Here, a specific key input release method, a password input release method, a time setting release method, and a profile release method will be described as an example.

As a result of determining the data protection mode release method 205, in the case of a specific key / password input release method, for example, a specific key such as "# 124 #" or a password such as "1234" is input (206), and time setting is released. In the case of the method, a time zone in which the data protection mode should not be operated, for example, 9 am to 5 pm is input (207), and in the case of the profile release method, a specific profile, for example, an indoor mode selection signal, is input (208). ).

Here, the data protection mode release method may be set in duplicate according to the characteristics of each data protection mode release method. That is, the user may preset two different types of data protection mode release methods, and then perform an authentication process according to one of the data protection mode release methods, so that the data protection mode may be released upon success. For example, when the specific key input release method and the time setting release method are set to be duplicated, when the authentication process according to the specific key input release method is successfully performed in the time zone operating in the data protection mode, the time setting release method is performed. The data protection mode can be released (in this case, temporary release) even if it violates the setting value of.

Subsequently, the controller 15 controls the counterfeit data received from the user through the input unit (keypad) 13 and a specific condition (specific time zone or profile) for releasing the data protection mode release password (specific key or password) or data protection mode. ) Is stored in the storage unit 12 (209).

3 is a flowchart illustrating an operation of a data protection mode when a message is received in a wireless communication terminal according to the present invention. Here, the data protection mode operation when receiving a message (for example, a short message / multimedia message) among various situations on the wireless communication terminal will be described as an example. In addition, a case where a specific key / password input release method is used as the data protection mode release method will be described as an example.

First, the control unit 15 determines whether or not to receive the message (301), if not received, performs a general operation in the wireless communication terminal (310), and terminates, if received, the transmission telephone number of the received message is In operation 302, it is determined whether or not the telephone number is set as the data protection mode operation target (ie, whether or not a message is received from the telephone number set as the data protection mode operation target).

As a result of determining whether the data protection mode is set (302), if the data protection mode is not set, after performing a general operation when receiving a message (311), and exits if the data protection mode is set, which data protection mode is released. It is determined whether the method is set (303).

In the result of determining whether the data protection mode release method is set (303), in the case of a specific key input release method, forgery data stored in the storage unit 12, that is, the content of the forgery message is output through the display unit (LCD) 14 ( 304) Then, it is determined whether or not a specific key corresponding to the data protection mode release password stored in the storage unit 12 is received through the input unit (keypad) 13 (305). In response to the input of the specific key corresponding to the input of the actual data, that is, the actual message content through the display unit (LCD) 14 (306) (here, if the specific key is not input, it ends).

On the other hand, in the result of determining whether the data protection mode release method is set (303), in the case of the password input release method, a predetermined password input window is output through the display unit (LCD) 14 (307) and stored in the storage unit 12 beforehand. It is determined whether a password corresponding to the data protection mode release password has been input (308), and according to the input of a password matching the data protection mode release password, the process proceeds to step 306 of outputting the actually received message content. In operation 309, the content of the forgery message stored in the storage unit 12 is output as it is not received.

In the above embodiment, a specific key input release method and a password input release method have been described as an example. For example, when a password input release method and a profile release method are set together, authentication is performed according to one of the two release methods. As soon as the process has been performed successfully, it is possible to release data protection mode (in this case, temporary release). That is, if the data protection mode is temporarily released in the indoor mode by the profile release method, the authentication process according to the password input release method is performed even if a message is received from the telephone number preset in the data protection mode while the wireless communication terminal is operating in the indoor mode. It is possible to output the actual data without doing this.

4 is a flowchart illustrating a data protection mode operation process when a list is output in a wireless communication terminal according to the present invention. Hereinafter, a specific key input release method will be described as an example of a data protection mode release method.

First, as the control unit 15 receives a request signal for outputting a list through an input unit (keypad) 13 from a user (401), a forgery list for a corresponding list (for example, a phone book list or a message list). And outputs (402). In this case, the counterfeit list may be a counterfeit data item that is preset in the data protection mode, and the other items may be a list other than the counterfeit data.

Thereafter, the controller 15 determines whether a specific key (for example, # 124 #) corresponding to the data protection mode release password has been input (403), and outputs the actual list according to the input (404), Terminate when no input is received. Of course, instead of receiving a specific key corresponding to the data protection mode release password, the actual list may be output even when a predetermined specific condition for releasing the data protection mode is satisfied.

5 is a flowchart illustrating an operation of a data protection mode when a specific item in a list is output in a wireless communication terminal according to the present invention. Here, the password input release method will be described as an example of the data protection mode release method.

First, in response to receiving an output request signal for a specific item from a list (eg, a received message list), the controller 15 determines whether the selected specific item is an operation target of the data protection mode (501). 502). That is, it is determined whether the phone number-related data is set as the operation target of the data protection mode.

As a result of the determination (502), when the data protection mode is set, it is determined whether or not a password corresponding to the data protection mode release password has been input (503). If it is not received (504), if not received forgery data (for example, the content of the forgery message) is output (505).

On the other hand, if the determination result 502, the data protection mode is not set, the process proceeds to the step of outputting the actual data (504).

6A and 6B illustrate an exemplary embodiment of a dual data protection mode operation process when a phone book is output in a wireless communication terminal according to the present invention. Here, an example in which a specific key input release method is set as the data protection mode release method will be described.

As shown in FIG. 6A, as the output of the telephone book list is requested, a counterfeit telephone number as counterfeit data and an actual telephone number as actual data are output together (61). Of course, the user cannot distinguish the fake data and the real data from each other until the data protection mode is released. Subsequently, in response to receiving a data protection mode release password (that is, a specific key corresponding to the data protection mode release password) from the user, the actual phonebook list is output (62). In other words, it outputs actual phone numbers, not fake telephone numbers. For example, the counterfeit phone number "011-123-2233" is output in the list display mode, but the actual phone number "011-232-3456" may be output as the data protection mode release password is input. As another example, the fake telephone number "016-234-3456" is output, but the actual telephone number "011-908-3476" may be output as the data protection mode release password is input. Here, in order to distinguish between the target phone number and the non-target phone number of the data protection mode from the outputted phone book list, the target phone of the data protection mode by changing colors (eg red) or fonts (eg italic). You can print the number.

On the other hand, as shown in Figure 6b in response to the request for the output of the registration information of the telephone number set as the operation target of the data protection mode, forged registration information, that is, forged telephone number, fake name, fake title, etc. (63). For example, "082-26-1223-2233" as a fake telephone number, "Hong Gil Dong" as a fake name, and "Oversea buyer" as a fake title can be output. Here, some detailed items (eg, registration time) that do not require protection may output actual data. Subsequently, in response to receiving the data protection mode release password from the user, actual data, that is, actual telephone number "016-576-2723" and the actual title "girlfriend" are output (64).

Here, the data protection mode may be set dually (or multiplely) for each step of the menu. That is, when the phone book list is output, the data protection mode is operated, and the counterfeit data is output. However, when the data protection mode release password is input, a list of the actual phone numbers is output. After receiving the selection signal, the data protection mode is output again, and the counterfeit data is output, and the data protection mode release password (the value may differ from the data protection mode release password received above). Data can be output. In addition, when the data protection mode is set in duplicate (or multiple) in each step of the menu, the detailed data protection mode set in each step may be different.

7A and 7B are diagrams illustrating an embodiment of a dual data protection mode operation process when a received short message list is output in a wireless communication terminal according to the present invention.

As shown in FIG. 7A, the received short message list is outputted together with the fake data and the actual data (71), and the actual data, that is, the actual received short message list is output as the data protection mode release password is input (72). ). For example, "!! Go to work on Sunday !!" is output as counterfeit data, but the actual data "8 am go fishing" can be output as the data protection mode release password is input.

On the other hand, as shown in Figure 7b, in response to the output request signal for the message received from the telephone number set as the target of the data protection mode, forgery data, that is, the fake telephone number "011-123-2233" and the fake message Contents "** How are you? ** Regardless of your friends." An old friend printed "(73), but the actual phone number" 016-576-2732 "and the actual message message" I love you. Work hard today. "

In the above detailed description, the telephone number is an example of an identifier that is a subject of the data protection mode. However, all data related to the identifier is collectively assigned as a specific value unique within the wireless communication terminal such as a person's name. Can be protected.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention outputs forged data to unauthenticated persons and actual data to authenticated users when an attempt is made to access data preset as an operation target of the data protection mode. It has the effect of protecting important information.
