The present invention relates to a mobile communication terminal, a control method thereof, and a location-based variable password setting system.

With the development of mobile communication technology, the penetration rate of mobile communication terminals is increasing day by day, and users can use various mobile communication services without limitation of time and space.

By the way, when the user is away from the mobile communication terminal another person can operate the mobile communication terminal to view the information stored in the mobile communication terminal, such as the short message transmission and reception history, call history, incoming call history, address book, etc. A password is set in the communication terminal. However, since the current mobile communication terminal has a single password system, if a password is exposed to another person, the entire information in the mobile communication terminal is provided.

In addition, if the mobile communication terminal is set to the lock mode using a password, there is a problem that a person in close relationship with the user of the mobile communication terminal may cause discomfort when attempting to operate the mobile communication terminal.

The present invention has been made to solve the above-mentioned disadvantages and problems, applying a multi-password system that can set at least two passwords to the mobile communication terminal, but differently set the password according to the place, by a specific password in a specific place Technically, to provide a mobile communication terminal and a control method thereof, and a location-based variable password generation system for improving the security of personal information and protecting privacy by selectively providing only secure information. There is.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the mobile communication terminal means any mobile communication device such as a PCS, a cellular phone, a PDA, a notebook PC, and the like.

1 is a view for explaining the configuration of a mobile communication terminal whose password is changed according to the position according to the present invention.

As shown, the mobile communication terminal 100 is a control unit 10 for controlling the overall operation of the mobile communication terminal 100, a wireless communication unit 20 for performing wireless communication with the mobile communication system, a plurality of GPS satellites GPS receiver 30 for receiving the position coordinates from the memory, memory 40 for storing the data necessary for the operation of the mobile communication terminal, user information, etc., input device 50 for receiving key input, voice input, etc. from the user ), An output device 60 for outputting information required when using various services through the mobile communication terminal and a multiple password module 70 for controlling multiple passwords according to the location, and the output device 60 is voice A voice output unit 62 for output, a speaker 64, and a display unit 66 for visual display of information.

Here, the multi-password module 70 stores the multi-password according to at least one or more locations and at least one data group in the memory 40, and confirms the current location when the password is input through the input device 50, The password inputted to the input device 50 and the password stored in each location in the memory 40 are compared, and if a matching password exists, the corresponding information in the data group secured by the corresponding password is output through the output device 60. to provide. Here, the data group can be arbitrarily classified by the mobile terminal user as needed, and one data group includes one or more data. In addition, the location information is stored in latitude and longitude coordinates, it is preferable to set to have a sufficient margin in consideration of the moving range of the mobile communication terminal in the location. That is, the location information is not a single coordinate but a value having a range that can cover a specific location.

For example, the user of the mobile communication terminal 100 sets the password for data group 1 (address book) to 1111 and the password for data group 2 (address book and call details) to 2222 at the place A. In B, a password for data group 1 (address book and short message view) is set to 3333, and a password for data group 2 (origin / call details) is set to 4444.

When the password 1111 is input to the mobile communication terminal 100 set as described above, the multiple password module 70 of the mobile communication terminal 100 first checks the current location of the mobile communication terminal 100. If the current location coordinate is a coordinate value included in the location A, the multi-password module 70 includes the password 1111 inputted to the input device 50 in at least two or more passwords for the data group set at the current location A. Check if it is In this example, since the password 1111 is set as a password for the data group 1 (address book access), the multi-password module 70 releases the information secured by the password 1111, that is, the address book, and releases the output device 60. Print the address book via

In the above, a case where different passwords are set according to a place and a data type is taken as an example. However, in some cases, the passwords may be set to overlap.

FIG. 2 is a detailed configuration diagram of the multiple password module shown in FIG. 1.

The multi-password module 70 of the mobile communication terminal 100 according to the present invention includes a password generation unit 71, a security parameter setting unit 73, a position determination unit 75, a password determination unit 77 and a data filtering unit. (79).

The password generator 71 receives a password for each location and a data group through the input device 50 and stores it in the memory 40. At this time, the location information is set directly by receiving the position coordinates directly by the user, or sets the designated margin, or when the user inputs the name, transmits the name input by the user to a separate positioning system connected to the mobile communication system and When the coordinates corresponding to the received place name are extracted and transmitted to the mobile communication terminal through the mobile communication system, it may be obtained by setting a margin specified in the received coordinate information. In addition, the multi-password according to the location may be set not only through the mobile communication terminal 10, but also by using a personal computer, and download and use the set password to the mobile communication terminal, which will be described in detail later.

In an embodiment of the present invention, the data stored in the mobile communication terminal may be divided into a general data group and a secure data group. In this case, as shown in FIG. 3, the password is databased and stored in the memory 40. Types of data included in the general data group and the secure data group may be classified according to the location of the mobile terminal user. 3 is an exemplary diagram of a password database created by the present invention, for example, a general password n for data group 1-n and a security password 2-n for data group 2-n are set at location n. I can see that there is.

 In addition, the data of the mobile communication terminal may be further divided into three or more groups as well as general data groups and security data groups according to a user's needs, and different passwords may be set for desired positions for each data group.

The security parameter setting unit 73 activates / deactivates a parameter for determining whether to display data stored in the mobile communication terminal. For example, the security parameters of all data (or data in the secure data group) before the password is entered will be in an active state, and if the password entered through the input device 50 matches the password set at the location The parameter setting unit 73 deactivates a security parameter of data secured by the corresponding password.

When the password is input through the input device 50, the location determining unit 75 determines the current location of the mobile communication terminal using the GPS receiver 30, and the current location coordinates of the mobile communication terminal are set by the user. In addition, the password determination unit 77 checks whether the password entered through the input device 50 is included in the multi-password set at the current position of the mobile communication terminal, and enters the password when a password error occurs Checks if the number of times exceeds the specified upper limit. In addition, the data filtering unit 79 deactivates the security parameter of the data secured by the password input through the input device 50 when the password is determined as a result of the check by the password determination unit 77, the corresponding data is outputted Output through device 60.

For example, when data in a mobile communication terminal is classified into a general data group and a security data group, a security parameter is assigned to data belonging to the security data group and is activated. In this state, when the general password set in the location is input to the mobile communication terminal, the data included in the general data group is output. When the security password set in the location is input, the security assigned to the data belonging to the security data group is input. After deactivating the parameter, output both general data and security data.

4 is a conceptual diagram illustrating a multi-password operating method according to an embodiment of the present invention. In the drawing, a multi-password application device refers to a mobile communication terminal, and sets two passwords in a mobile communication terminal. Indicates.

In this embodiment, the user classifies the data stored in the mobile communication terminal into a general data group and a secure data group. Then, a desired password is set for each of the general data group and the secure data group, and different passwords are set according to the location (see FIG. 3). Here, the general password is a password that secures information that may be disclosed to others, and the security password may be defined as a password that secures information that should not be disclosed to others. When a password is assigned to each of the general data group and the secure data group, the security parameter P of the secure data group is activated.

When the password is input while the password is set as described above, and the input password matches the general password among the passwords set at the current location, the security parameter setting unit 73 of the multi-password module is secured by the secure password. The security parameters of the data 2, the data 4, the data 5, the data 7, the data 8) are kept in an active state, and the data filtering unit 79 performs the rest of the data (data 1, data 3, Data 6, Data 9, and Data 10 are displayed.

On the other hand, if a password is input, and the input password matches the security password among the passwords set at the current location, the security parameter setting unit 79 secures the data (data 2, data 4, data 5, After changing the security parameters of data 7, data 8) to an inactive state, all data are output.

 In addition, the data of the mobile communication terminal may be further divided into three or more groups as well as general data groups and security data groups according to a user's needs, and different passwords may be set for desired positions for each data group.

5 is a flowchart illustrating a method for controlling a mobile communication terminal according to the present invention, which shows a control method when data in the mobile communication terminal is classified into two groups, a general data group and a secure data group.

To this end, the user must first set a password according to at least one location and data group, and as the user sets a password, a process of assigning a security parameter to data belonging to the secure data group and activating it must be performed. do. The location information selected by the user to apply the multi-password is stored in latitude and longitude coordinates, it is preferable to set to have a sufficient margin in consideration of the moving range of the mobile communication terminal in the location. That is, the location information is not a single coordinate, but has a range that can cover a specific location.

As described above, when a password is input through the input device 50 of the mobile communication terminal in the state where the password is set (S100), the position determining unit 75 of the multi-password module 70 is received through the GPS receiver 30. The current location coordinates of the mobile communication terminal are checked with reference to the location coordinates (S102). That is, the current location coordinates of the mobile communication terminal is to determine whether the coordinates are included in the location information selected by the user to apply the multiple passwords, and which of the at least one location information is included in the location information.

After confirming the current location of the mobile communication terminal, the password determination unit 77 checks whether the password input in step S100 is a general password set at the current location of the mobile communication terminal (S104), and matches the general password. The data filtering unit 79 filters the data for which the security parameter is activated (S106), and outputs the data for which the security parameter is not set through the output device 60.

On the other hand, if the password entered in step S104 as a result of the determination by the password determination unit 77 does not match the general password, the password determination unit 77 checks whether the password entered again matches the security password (S110). As a result of the check, if the security password matches, the security parameter setting unit 73 switches the security parameter assigned to the data belonging to the secure data group to the inactive state (112), and all the data included in the general data group and the secure data group. The output through the output device 60.

In addition, if the password entered as a result of the check in step S110 does not match the security password, that is, if a password error occurs, check whether the number of password inputs is equal to or lower than a specified password input frequency upper limit (setting value) (S116), If the number of inputs is less than or equal to the set value, the password is re-entered and the process proceeds to step 104 where the subsequent process is performed. On the other hand, if the number of incorrect password inputs exceeds the set value, the mobile terminal can be used after a designated time elapses or the mobile terminal is stopped. It can help prevent accidents.

6 is a view for explaining a location-based variable password setting system applied to the present invention.

The multi-password according to the location is not only directly set through the mobile communication terminal 10, but also set a password through a personal computer, it is also possible to download and use the set password to the mobile communication terminal, Figure 6 The location-based variable password setting system 500 and a communication network configuration to which the system is applied are shown.

The user of the mobile communication terminal 100 accesses the location-based variable password setting system 500 through the Internet 400 using the personal computer 200. And, it is to set a multi-password according to the position, when using a separate location-based variable password setting system 500 in the present invention, even if the user does not know the coordinates of the position to set the password easily set the password It becomes possible.

That is, in the case of setting a password directly on the mobile communication terminal 100, the user directly inputs the location coordinates, or when the user inputs a place name, the mobile communication terminal wirelessly connects to a separate positioning system to locate the location coordinates for the place name. Although it is inconvenient to receive, but if you set the password by wired access to the location-based variable password setting system 500 using a personal computer 200, even if the user does not know the name of the desired location setting password without burden You will be able to carry out the process.

The controller 510 controls the overall operation of the location-based variable password setting system, and the communication network interface 520 enables communication with the Internet 400 and the wireless network 300.

The user manager 530 stores and manages user information (ID, password, mobile communication terminal number, etc.) of the personal computer 200 wired through the Internet 400 in the database 560.

The place name-coordinate conversion unit 540 performs a function of converting the place name of the desired location by the user who wants to set multiple passwords according to the location into coordinate information. At this time, the coordinate information input by the user is preferably set to have a sufficient margin in consideration of the movement of the mobile communication terminal in the location. In addition, when the user selects a desired location, the password setting unit 550 classifies the data group necessary for the data of the mobile communication terminal at the corresponding location, and receives the password of each data group at each location and receives the database 560. Store in

When multiple passwords are set according to the location as described above, the communication network interface 520 transmits the set password database to the corresponding mobile communication terminal by using a push proxy gateway or SMS of the mobile communication system. The password database is loaded so that it can be applied to subsequent mobile communication terminal operations.

In addition, after the password database is transmitted to the mobile communication terminal, it is preferable to perform an authentication process for confirming whether the mobile communication terminal user is a legitimate user before the mobile communication terminal user loads the password. This authentication process is to transmit the user ID, password and the like managed by the user management unit 530 when the location-based variable password setting system 500 transmits a password, the mobile terminal user to receive and load the password database In this case, it is possible to apply all possible authentication methods such as requesting ID and password input and checking whether ID and password match.
