The objects, features and advantages of the present invention described above will be more clearly understood through the following detailed description taken in conjunction with the accompanying drawings. For convenience of explanation, the following embodiment describes a method and system for authenticating a user of a personal computer. 1 to 6 will be described in detail with respect to the user authentication method and system using a color pattern according to an embodiment of the present invention.

1 is a block diagram showing a user authentication system using a color pattern according to the present invention. 1, a user authentication system according to the present invention includes a keyboard 10, a mouse 20, a controller 30, a random access memory (RAM) 40, and a read only memory (ROM) 50. ), Pattern data memory 60, cryptographic editing memory 70, cryptographic data memory 80, color display driver 90 and monitor 100. FIG.

The keyboard 10 and the mouse 20 are connected to the control unit 30 to transmit a command or data input by the user to the control unit 30. Here, the keyboard 10 includes a plurality of character keys 12 for inputting characters, a plurality of direction keys 14 for moving the cursor (Cursor) up, down, left, and right directions, and a tab key for tabbing the cursor. (16) and an icon (Icon) on the monitor 100, i.e., a selection key 18 for selecting a color and pattern unit to be described later. The mouse 20 includes a movement signal generator 22 for generating a signal for moving a mouse pointer and a click switch 24 for selecting a color and pattern unit on the monitor 100. Equipped.

The controller 30 controls the RAM 40, the ROM 50, the pattern data memory 60, the password editing memory 70, and the password data memory 80 to control the keyboard 10 or the mouse 20. The user command or data input is processed, and the processed result is provided to the monitor 100 through the color display driver 90.

The RAM 40 includes a general data memory 42 and a password registration flag 44 in which general data is stored. The general data memory 42 stores data that can be changed by the accessed user. The password registration flag 44 indicates whether or not the user has registered password data, and is confirmed by the controller 30 at boot time. In the present embodiment, the password registration flag 44 is set to "1" when encrypted data is registered, and set to "0" when encrypted data is not registered.

Referring to FIG. 2, the ROM 50 includes a system program area 52 in which a system program for controlling the operation of the entire system according to the present invention is stored, and a mode process for processing data stored in the RAM 40. A mode processing program area 54 in which a program is stored, and a control program area 56 in which a control program for registering or comparing encryption data for authentication of a user is stored. Programs stored in the ROM 50 are read and driven by the controller 30. For example, when the user boots the system, the controller 30 reads a program stored in the system program area 52 to activate the entire system. At this time, the controller 30 checks whether the password registration flag 44 is set to "0" or "1", and drives the program for the next operation according to the check result.

The pattern data memory 60 stores a plurality of colors and a plurality of pattern units for generating cipher data to be registered or comparison cipher data to be compared with the registered cipher data, and key values of the respective color / pattern units. Referring to FIG. 3, the pattern data memory 60 includes red, green, blue, blue green, magenta, yellow, white, and black colors 62, and key values 62a for each of the colors 62. FIG. And a plurality of pattern units 64 arranged in the form of a 4x4 matrix, and key values 64a of the respective pattern units 64. In this case, the number of cryptographic data that can be formed using the color and the pattern unit stored in the pattern data memory 60 in this embodiment is about 2.8 x 10 ¹⁴ pieces. As described above, the plurality of colors 62 and the pattern unit 64 stored in the pattern data memory 60 are monitored by the control unit 30 in the form of a color / pattern input unit (see FIG. 6) when the user inputs encrypted data. Displayed on the screen of 100. At this time, the key values 62a and 64a of the respective color and pattern units are not displayed on the screen of the monitor 100. Here, the key value 62a of each color is preferably assigned in combination of the order in the alphabet of the first two digits of the English notation of the color. For example, red is the English letter "RED", "R" is the 18th alphabet, "E" is the fifth alphabet, and the red key value is the first two digits "R" and "RED". "185" in combination with the alphabetical order of "E". When two or more colors having the same alphabet of the first two digits of the English notation exist, the key values of the colors are assigned in combination in the order of the first three digits of the alphabet. For example, since the blue letter is "BLUE" and the black letter is "BLACK", the blue key value is a combination of the first three digits "B", "L" and "U" in alphabetical order. &Quot; 21221 &quot;, and the black key value is " 2121 " combining the first three digits " B &quot;," L " and " A " Accordingly, the green key value is "718", the blue key value is "21221", the blue green key value is "325", the crimson key value is "131", the yellow key value is "255", and the white key value is "238". ", And the black key value is" 2121 ". The key value 64a of each pattern unit is assigned by sequentially combining the coordinate values on the horizontal axis (X axis) and the coordinate values on the vertical axis (Y axis) of each pattern unit. Accordingly, the key values of each pattern unit are 11, ..., 14, 21, ..., 24, 31, ..., 34 and 41, ... 44. On the other hand, the number of the color and the number of the pattern unit can be increased or decreased. If the number is increased, the number of cases that can generate the encrypted data is increased, and if the number is reduced, the encrypted data is reduced. The number of cases that can be generated is reduced.

The password editing memory 70 generates and stores registration password data or comparison password data by combining at least one color selected by the user and key values for the pattern unit. As shown in Fig. 4, when the user sequentially selects a pattern unit having red and (X, Y) coordinates of (1, 2) as the cipher data, the cipher editing memory 70 has a red key value. The unit key value "18512" is stored by combining "185" and the key value "12" of the selected pattern unit. Subsequently, when the user selects a different color and selects a pattern unit corresponding to the selected color, the encryption editing memory 70 stores another unit key value through the above-described process. In this case, the user may select a plurality of pattern units without limitation for one color, and the color and pattern units selected by the user form a color pattern such as a predetermined picture, figure, or character familiar to the user. . When a predetermined cipher data editing signal is generated from the controller 30, the cipher editing memory 70 combines the stored unit key values regardless of the order of selection of the color and pattern units to combine one cipher data. Create In this embodiment, the cipher editing memory 70 generates the cipher data by arranging the unit key values in the order of the sum of the numbers constituting the unit key value. However, the present invention is not limited thereto, and in another embodiment of the present invention, the encryption editing memory 70 may include data on the selection order of the predetermined pattern unit selected in the encryption data. For example, each of the unit key values of the first selected pattern unit and the last selected pattern unit may be arranged at the beginning and the end of the encryption data to generate encrypted data. At this time, the control unit 30 stores the encrypted data generated by the password editing memory 70 in the encrypted data memory 80 as registration password data, or the registered password stored in the encrypted data memory 80 as comparative password data. Compare with data. As a result of the comparison, when the comparison password data matches the registration password data, the controller 30 generates an authentication signal and allows the user to access the general data memory 42 of the RAM 40. On the other hand, when the comparison result, the comparison password data does not match the registration password data, the control unit 30 generates a signal that cannot be authenticated.

The cipher data memory 80 stores cipher data registered by a user.

The monitor 100 displays data, for example, a color / pattern input unit, provided from the controller 30 through the color display driver 90 on a screen. When the user selects a predetermined color and pattern unit by using the keyboard 10 or the mouse 20, the monitor 100 displays a predetermined color pattern composed of the selected color and pattern unit. Preferably, the screen itself of the monitor 100 is a touch screen capable of generating a selection signal for the color / pattern input unit to be displayed. In this case, the monitor 100 having the touch screen is a user terminal that allows a user to input a predetermined command or data and check the data processed by the controller 30.

5 is a flowchart illustrating a process of authenticating a user and registering cryptographic data using the system of FIG. 1. 1 and 5, when the user boots the system to access data stored in the general data memory 42 of the RAM 40 (S100), the controller 30 may determine the ROM 50. The entire system is activated by driving a system program stored in the system program area 52. Then, the controller 30 checks whether the password registration flag 44 of the RAM 40 is set to "1" (S102).

In the checking step (S102), when it is confirmed that the password registration flag 44 is set to "1", the control unit 30 is a control program stored in the control program area 56 of the ROM 50 Drive to perform the user's authentication procedure.

In this case, the controller 30 first extracts the information stored in the pattern data memory 60 and displays the color / pattern input unit on the monitor 100 (S110). Referring to FIG. 6, the color / pattern input unit includes a plurality of color selection buttons to be selected by a user, a plurality of pattern unit buttons, a confirmation button, and an erase button for deleting the selected pattern unit. Subsequently, when the user selects a color on the color / pattern input unit by using the keyboard 10, the mouse 20, or the touch screen, the controller 30 receives a selection signal for the color (S115). At this time, the controller 30 transmits a color selection signal to the cipher editing memory 70, and the cipher editing memory 70 stores the key value of the selected color (S120). Then, when the user selects the pattern unit on the color / pattern input unit, the control unit 30 receives the selection signal for the pattern unit (S125). In this case, the control unit 30 converts the selected pattern unit into a color received in step S115 and displays it on the monitor 100 (S130). At the same time, the control unit 30 transmits a pattern unit selection signal to the cryptographic editing memory 70, and the cryptographic editing memory 70 stores the key value of the selected pattern unit (S135). Subsequently, the encryption editing memory 70 combines the key value of the color stored in the step S120 and the key value of the pattern unit stored in the step S135 to generate and store a predetermined unit key value (S140). On the other hand, when the user selects one color and then sequentially selects a plurality of pattern units, the encryption editing memory 70 generates and stores unit key values for the selected color and each pattern unit, and displays the monitor ( 100 displays the predetermined color pattern.

Thus, the color pattern consisting of the color and the plurality of pattern units can be implemented regardless of the order of selecting the color and the pattern unit can be stored more easily than the number or a combination of numbers and letters.

At this time, the controller 30 checks whether a confirmation signal is received from the user (S145). In the checking step (S145), when the confirmation signal is received, the controller 30 generates an encrypted data edit signal, and the encrypted edit memory 70 uses one stored unit key value or multiple unit key values. Combination to generate the comparison password data (S150). At this time, the controller 30 compares the generated comparison password data with the registration password data stored in the encryption data memory 80 (S155). In the comparison step (S155), when the registration password data and the comparison password data match, the control unit 30 allows the user to access data stored in the general data memory 42 of the RAM 40 (S160). At this time, when a user requests access to predetermined data, the controller 30 drives a mode processing program stored in the mode processing program area 54 of the ROM 50 to process data desired by the user. And, in the comparison step (S155), if the registration password data and the comparison password data is inconsistent, the control unit 30 generates a non-authentication signal and displays a display indicating non-authentication on the monitor 100 ( S165).

On the other hand, in the irradiation step (S145), if the confirmation signal is not received, the controller 30 repeats the color selection signal receiving step (S115).

On the other hand, if it is confirmed in step S102 that the password registration flag 44 is set to "0", the controller 30 checks whether the user requests password registration (S210). In the checking step (S210), when the user requests a password registration, the controller 30 drives a control program stored in the control program area 56 of the ROM 50 to register the user's password. Perform

In this case, the controller 30 extracts the information stored in the pattern data memory 60 and displays the color / pattern input unit on the monitor 100 (S215). Then, the control unit 30 receives a selection signal for a specific color (S220), storing a key value of a specific color selected in the encryption editing memory 70 (S225), and a selection signal for a specific pattern unit. Receiving (S230), displaying the selected specific pattern unit on the monitor 100 in the selected specific color (S235), and storing the key value of the selected specific pattern unit in the encryption editing memory 70 (S240). In step S245, the unit key value is generated by combining the selected specific color and the key value of the specific pattern unit, and the step S250 of checking whether a confirmation signal is received from the user is sequentially performed. Here, each step (S220, S225, S230, S235, S240, S245, S250) is substantially the same as each step (S115, S120, S125, S130, S135, S140, S145) for generating the above-described comparison code data Since the same, detailed description thereof will be omitted.

Then, in the checking step (S250), when the confirmation signal is received, the controller 30 generates an encrypted data edit signal. In this case, the encryption editing memory 70 generates predetermined registration encryption data by combining the unit key values stored in response to the encryption data editing signal (S255). At this time, the controller 30 stores the generated registration password data in the encryption data memory 80 (S260). Then, the controller 30 performs a step S160 of allowing a user to access data stored in the general data memory 42 of the RAM 40. On the other hand, in the irradiation step (S250), if the confirmation signal is not received, the controller 30 repeats the step (S220) of receiving a selection signal for a specific color.

In addition, in the checking step (S210), when there is no user's password registration request, the controller 30 allows the user to access data stored in the general data memory 42 of the RAM 40. (S160).

In addition, the above-described embodiments of the present invention may be written as a program that can be executed in a computer. And, using a medium used in a computer, it can be implemented in a general-purpose digital computer for operating the program. The medium may be a magnetic recording medium (for example, a ROM, a floppy disk, a hard disk, etc.), an optical reading medium (for example, a CD-ROM, a DVD, etc.) and a carrier wave (for example, Recording media such as, for example, transmission via the Internet.

An embodiment of the recording medium records a method for authenticating a user, and registers data for authentication of the user by combining a key value of each color and pattern unit constituting at least one specific color pattern input by the user. A) module for storing in the memory; A B) module for providing a color / pattern input unit configured to input a color pattern to the user through a user terminal; A C) module which generates comparison password data by combining key values of each of the color and pattern units constituting the color pattern input by the user on the color / pattern input unit; A module for confirming whether the registration password data and the comparison password data match; And an E) module for generating an authentication signal for the user when the registration password data and the comparison password data match.

Functional modules for implementing the present invention as described above can be easily implemented by programmers with average knowledge in the technical field to which the present invention belongs.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. . For example, in the above-described embodiment, the computer is illustrated and described as authenticating a user who wants to access data stored in the RAM 40, but the present invention is not limited thereto. It can also be used to authenticate a user accessing another computer or website through a predetermined communication network such as the Internet using a terminal equipped with a mouse and a monitor.

In addition, the key value of the color and the pattern unit is not limited to the above-described embodiment, but in another embodiment of the present invention, the system administrator may arbitrarily set the number or a combination of numbers and letters.

In addition, in the above-described embodiment, the registration password data is shown and described as being generated by combining the key values of the color unit and the pattern unit constituting one color pattern, but in another embodiment of the present invention, the registration password data is a plurality of consecutive numbers. It can be generated by combining the key values of the plurality of colors and the pattern unit, respectively constituting the color pattern of. In this case, in the system of the present invention, when the user who inputs the first color pattern clicks the next pattern button shown in Fig. 6, a new color / pattern input unit is displayed on the monitor 100 so that the user can input the next pattern. It becomes possible. By such a method, when a user inputs a plurality of color patterns, the plurality of color patterns are superimposed and displayed on the monitor 100 continuously.

Furthermore, in the above-described embodiment, although the encryption data is illustrated and described as being generated by combining the key values of the color unit and the pattern unit sequentially selected by the user, in another embodiment of the present invention, the pattern does not include the user in the color pattern. By selecting and deleting a unit, and selecting a color, it can be implemented to combine the selected color with the key values of the pattern unit which remain undeleted to generate encrypted data.

Meanwhile, when a plurality of users using the authentication method and system of the present invention configured as described above form a predetermined group (family), the users may register the group (family) password data. For example, in the case of a family group consisting of parents and children, the family group registers the family (group) password data using color patterns unknown to other groups or users, and sets the unique pattern of the parent to the family password data. In addition to this, it is possible to register encrypted data of all family members. In this case, the data stored in the general data memory 42 is divided into data that can be accessed using only family password data and data that can only be accessed by inputting a unique pattern added to the family password data. This can be applied to prevent a child from being exposed to harmful information by differentiating the data accessible to the parent and the data accessible to the child when the whole family subscribes to the information providing site using the data communication network. have. In addition, users in the family can remember the password data easily through other users in the family, even if the user forgets the family password data only by remembering their own unique patterns.

In another embodiment of the present invention, the registration password data may be composed of two data parts, for example, an identifier (I.D.) data for distinguishing a user from another user and a password data for identifying the user. In this case, the color / pattern input unit includes an I.D. input unit for inputting a color and pattern unit corresponding to I.D. data and a password input unit for inputting a color and pattern unit corresponding to password data. Here, the controller 30 displays the color and pattern units selected on the I.D. input unit on the monitor 100 and hides the color and pattern units selected on the password input unit so that they are not displayed on the monitor 100. As a variant of this, the color / pattern input unit may include a button for setting whether to input a color pattern corresponding to ID data or a color pattern corresponding to password data before selecting the color and pattern unit. . In this case, the controller 30 displays or hides the color and pattern unit selected according to the button setting signal on the monitor 100. As such, when the color pattern corresponding to some of the color patterns input through the color / pattern input unit, that is, the color pattern corresponding to the password data is hidden on the monitor 100, the authentication method and system of the present invention expose the user's registration password data to other users. Can be effectively prevented.

Therefore, the true technical protection scope of the present invention will be defined by the appended claims technical spirit.

According to the user authentication method and system using the color pattern of the present invention as described above, since the encryption data is generated regardless of the order of selecting the color and the pattern unit, regardless of the number of color and pattern units, Passwords are easier and more convenient to remember than a combination of numbers and letters.

Further, according to the user authentication method and system of the present invention, since the user can easily store the password, by increasing the number of color and pattern units to be selected, by greatly increasing the number of cases where encrypted data can be generated, The possibility of hacking can be significantly reduced.
