The present invention relates to a method for locking an application program or data file in a mobile communication terminal, and more particularly, in a mobile communication terminal capable of individually locking by setting a separate password for each application program or data file. It relates to a locking method for an application or data file.

Recently, a mobile communication terminal is a representative communication device that performs information transmission with the other party, and has become an important communication means indispensable in modern life. In addition to the basic call function and text message transmission function, the Internet connection function, photographing function, and music reception function are not only executed, but also a function for capturing video can be realized. Mobile communication terminals having such various functions are becoming a part of our life to become a necessity of life. However, as the use of mobile communication terminals, which are used for such important purposes, has been increasing, the use of mobile communication terminals by others other than users is a problem.

Conventionally, in order to solve this problem, a password is set in a mobile communication terminal to set a lock function. However, since a lock function is set for all functions of the mobile communication terminal, the terminal is set a password every time a user calls or uses various functions. Providing a screen for inputting the user has been inconvenient to enter and use a password every time. In addition, since only one password is set for all functions of the mobile communication terminal to use the lock function, there is a problem in that the use of the mobile communication terminal by another person cannot be prevented when one set password is leaked.

The present invention has been proposed to solve the above problems, the object of which is to lock the application or data file in a mobile communication terminal that can individually perform a lock function by setting a password for each application or data file To provide a method.

The present invention for achieving this object is a first step of storing a password when a user registers a password for the application and a first check whether the lock function for the application is set when the user requests access to the application And a second step of displaying a password input request if the lock function is set, and a fourth step of releasing the lock function for the corresponding application if the received password is a stored password.

In addition, if the lock function for the application is not set as a result of the check in the second step, the process can be performed by allowing access to the program. If the password entered is not a stored password, a password re-entering request is displayed. It is also possible to repeat the re-entry request until the entered password is a registered password.

In addition, when the password corresponding to the application is stored in the first step, a lock function is automatically set for the corresponding application, and a separate password can be set for each application.

According to another embodiment of the present invention, a first step of storing a password when the user registers a password for the data and a second step of checking whether a lock function for the data file is set when the user requests access to the data file; And a fourth step of displaying a password input request if the lock function is set, and a fourth step of releasing the lock function for the corresponding data file if the received password is a stored password.

For each of these data, access rights can be set differently according to the password, and the configurable access rights can include access rights to read the data file only when the corresponding password is entered. In addition, the configurable access rights may include access rights for reading and writing the data file when the corresponding password is entered.

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

1 is an internal configuration diagram showing an internal structure of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication terminal according to the present invention includes an input unit 110, a display unit 120, a controller 130, a wireless circuit unit 140, a memory unit 150, and an audio converter 160. do.

The input unit 110 may use various elements such as a keypad and a touch screen, and is used when a user selects a desired function or inputs information.

The display unit 120 displays the state and operation process of the mobile communication terminal.

The controller 130 controls the overall state and operation of the mobile communication terminal and may include a microprocessor or a digital signal processor (DSP). Particularly, in the present invention, the controller 130 checks whether a lock function is set for the application or data file when the access request is made to the application or data file, and displays a password input request if the lock function is set. If you do not have control and locks set up, you can control the process for the application or data file. That is, according to the present invention, since a separate password can be set individually by setting a separate password for each application or data file, the controller 130 checks whether the locking function is individually set when an access request for the application or data file is made. To judge.

The wireless circuit unit 140 is a transmission / reception circuit for transmitting and receiving voice and control information with a base station wirelessly. Receives a call signal sent by the sender's mobile communication terminal through the antenna and transmits it to the controller 130 or transmits data stored in the memory unit 150 to the receiver's mobile communication terminal through the antenna. do.

The memory unit 150 stores programs and data necessary for the operation and status of the mobile communication terminal or the control of the controller 130, and includes various types of erasable programmable read only memory (EPROM), static random access memory (SRAM), and flash memory. The device can be used. In particular, in the present invention, the memory unit 150 stores a password set for each application program or data file. In addition, when the user sets the access authority method according to the password, the memory unit 150 stores it.

The audio converter 160 processes the voice signal of the user input through the microphone (MIC) in a form for transmitting the voice signal through the wireless circuit unit 140, and the voice signal of the call partner input through the wireless circuit unit 140 or the like. It serves to process various audio signals generated by the controller 130 into signals of a type that can be output from the speaker SPK.

Next, FIG. 2 is a flowchart illustrating a lock function setting according to the present invention.

The user selects an application or data file to execute the lock function (S201). First, an embodiment of selecting an application program will be described below. For example, as shown in FIG. 4A, when a user selects an application item, the terminal displays an application program including a built-in call record, message management, camera, phone number management, and game. Display. An example of the screen at this time is shown in Fig. 4B.

Examples of screens at the time of selecting a data file are shown in Figs. 4A, 4F, and 4G. In FIG. 4A, when a user selects a data file, each item for an MP3 file, a video file, and a photo file embedded in the terminal is displayed as shown in FIG. 4F. If the user selects an MP3 file item, the terminal displays all the MP3 files embedded in the terminal for the user to select. An example of the screen at this time is shown in Fig. 4G.

 That is, since the present invention is to set a separate password by setting a separate password for each application or data file, first of all, the application or data file to be executed is selected.                     

In such a situation, a password for the corresponding application or data file is registered (S203). For example, if a user selects a lock function for message management as shown in FIG. 4B, the terminal provides a screen for inputting a password to set a lock function for message management. When the user enters a separate password for message management, the terminal provides a screen for accessing different access rights according to the password.

In addition, for the data file, selecting the data file in the same manner as in the embodiment of the application program provides a screen for inputting a password and a screen for setting access rights according to the password.

For example, a password-based access method is to grant access to the application or data file only according to the password, or to make it inaccessible or read / write. In other words, the access rights for the application or data file are set differently according to the entered password. An example of the screen at this time is shown in FIG. 4D.

In this manner, information about the password set for each application or data file is stored (S205).

3 is a flowchart illustrating a locking and unlocking process for an application program or a data file according to the present invention.

When the user requests access to an application or data file (S301), the terminal checks whether a lock function for the application or data file is set (S303). In other words, if the user selects an application program consisting of message management, incoming / outgoing call recording, camera shooting, phonebook management, or a data file composed of MP3 files, video files, photo files, etc., the terminal selects the selected application or data. This is to check if the file has been previously locked.

If the check result lock function of step 303 is not set, access to the corresponding application or data file is allowed to perform the corresponding process (S305). For example, if the user requests access to the camera function and the terminal checks whether the lock function is set to the camera function, if the lock function is not set, the user can allow access to the camera function and use the camera function. To control.

On the other hand, if the verification result lock function is set in step 303, a password input request is displayed on the screen (S307). The password is the password saved when setting the lock function. As described above with reference to FIG. 2, since a password is set for each application or data file, when the terminal displays a password input request on a screen, the user must input a password corresponding to the application program or data file to be accessed.

When the user enters a password on the provided password input screen, it is checked whether the received password is a stored password (S309). As a result of the check, if the input password matches the stored password, the lock on the corresponding application or data file is released (S313).

As described above with reference to FIG. 2, access to the corresponding application or data file may be accessed by different access rights according to a password. For example, if you set the user to read and write the access method for the password you set when you set up a password for message management, and you set the password to match the password you entered to unlock the message management. It's about controlling what a user can read and write about.

If you set the password for message management to read only the access method for the password you set, you will be able to read the message and write the message even if the password you set later matches the password you entered.

That is, according to the present invention, an access right for an application or a data file can be set differently according to a password, so that even one application or data file can be given differently according to a password.

On the other hand, if the received password does not match the stored password as a result of the check in step 309 (S311) and displays the password re-entry request on the screen and repeats the re-entry request until the input password is the stored password.

As mentioned above, although this invention was demonstrated using the Example, these Examples are illustrative and not restrictive. Those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit of the invention.

As described above, according to the present invention, a method of locking an application program or data file in a mobile communication terminal capable of setting a lock function for each application program or data file is provided. Since the present invention can individually set a lock function for an application program or a data file, only a necessary function desired by a user can be set to provide a convenience for the user.

In addition, since a password can be set for each application or data file, even if one password is leaked to another user, the application or data file using a different password provides convenience for the user to use it with confidence.
