(First embodiment)

The fingerprint acquisition unit 11 sets the fingerprint authentication mode when a fingerprint authentication event occurs, and is obtained by the fingerprint sensor 61 of the fingerprint detection unit 60 in the fingerprint authentication mode as shown in S (Sensor) 2 of FIG. 4. When the pattern data is input, the fingerprint data is extracted from the fingerprint pattern data and outputted to the fingerprint authentication unit 12, and in the case of the fingerprint sensor function button mode, the fingerprint pattern data is output to the fingerprint button mode execution unit.

When fingerprint data is input from the fingerprint acquisition unit 11, the fingerprint authentication unit 12 requests registration fingerprint data from the security control unit 50, receives decoded fingerprint data, compares the fingerprint data with the input fingerprint data, and checks whether the fingerprint data is matched. According to the fingerprint authentication to determine the success.

Specifically, the fingerprint button mode execution unit 13 includes a fingerprint button recognition unit 14 and a button function execution unit 15.

In detail, when the fingerprint pattern data of the entire fingerprint sensor recognition region is input from the fingerprint acquisition unit 11, the fingerprint button recognition unit 14 determines the position of the region where the fingerprint data of the fingerprint pattern data is formed.

As shown in FIG. 5, when the user places the fingertip at the center of the fingerprint sensor area as D (Direction) 2, the fingerprint pattern data may be formed as 500. Fingerprint pattern data 500 may be composed of fingerprint data 501 and null data 502.

The fingerprint button recognition unit 14 superimposes the fingerprint pattern data 500 on the button pattern 600 corresponding to the fingerprint recognition sensor area, calculates the distribution of the fingerprint data 501 of the fingerprint pattern data 500, and recognizes the fingerprint. Calculate the position in the sensor area.

When the position is calculated, the fingerprint button recognition unit 14 recognizes that the button mapped to the position is pressed.

For example, the fingerprint button recognition unit 14 recognizes that the selection button S is pressed when the distribution of fingerprint data is concentrated in the center as shown in D2 in FIG. 5, and the fingerprint data 501-5 is stored as in D3. If it is concentrated toward the rear (left) area B side of the fingerprint sensor recognition area, the rear movement button B is recognized as pressed, and as shown in D4, the fingerprint data 501-4 is the next (below) area of the fingerprint sensor recognition area. If it is concentrated on the (N) side, the next button (N) is recognized as being pressed.

In addition, the fingerprint sensor recognition area is divided into nine areas and four corner areas (N / B, B / P, F / P, N / F) are set as buffer (boundary) areas without buttons. The recognition rate can be improved.

In addition, according to an embodiment of the present invention, as shown in D6 and D7 of FIG. 5, the previous movement button P may be allocated to the upper region P of the fingerprint sensor recognition region, but in general, the user may use a fingertip node. Since it is highly likely to press the upper area P and the center area S at the same time as in D7, it is preferable not to assign the previous move button P.

In addition, the fingerprint button recognition unit 14 recognizes that the function selection wait button is pressed when the selection button S is recognized only once, and the function selection button when the selection button S is input twice within a predetermined time. If the selection button S is input three times in succession at a predetermined time interval, the function selection end button may be recognized as being pressed.

The button function execution unit 15 executes a function corresponding to the recognized button when the button pressed by the user in the fingerprint button recognition unit 14 is recognized.

For example, when the main control unit 10 is pressed for more than a predetermined time, the function setting mode is set, and when the fingerprint sensor function button mode is set in the function setting mode, the button function is shown in FIG. Select whether to move the selection window (or cursor, etc.) 601 located in any menu (function) in the function menu table, such as forward (right), backward (left), next (down), or the like. It may be to wait for selection, to select, or to terminate the selection before selecting the menu (function) at the position where the window is placed.

The button function execution unit 15 may arrange the selection window 601 at a default position or a previous execution position when the function setting mode is initially driven.

The button function execution unit 15 executes the corresponding button function in response to the recognized button.

When the function setting mode is set, the button function execution unit 15 has the selection window 601 as' 1. If it is determined that the forward button is recognized while being placed in the 'membership' upper menu, the selection window will be moved to the '1.1 card' menu. However, if the function selection button (select button (S) is input twice in a row) is pressed in the '1.membership' menu, it may be configured as the submenu moves.

As another example, if it is recognized that the next move button is pressed, the button function execution unit 15 will move the selection window 601 to the upper menu of '2.

7 is a flowchart illustrating a multi-function input method using a fingerprint sensor of a security token card according to the present invention.

Referring to FIG. 7, the main controller 10 checks whether a fingerprint authentication event occurs (S111). The fingerprint authentication event may be generated when power is supplied from the power supply unit 40 or an RF signal reception notification signal is received from the security control unit 50 according to the input of the power button 41. In addition, the fingerprint authentication event may be generated when the power button 41 is input for a predetermined time or more and a function setting mode command is generated.

When the fingerprint authentication event occurs, the main controller 10 checks whether fingerprint data is acquired through the fingerprint detector 60 (S113).

When fingerprint data is obtained, the main controller 10 performs fingerprint authentication through the security controller 50 (S115).

If the result of the fingerprint authentication is successful, the main controller 10 sets the fingerprint sensor function button mode using the fingerprint sensor 61 as the button input device (S117).

When the fingerprint sensor function button mode is set, the main controller 10 checks whether the fingerprint pattern data is acquired through the fingerprint detector 60 (S119).

When the fingerprint pattern data is obtained, the main controller 10 recognizes the position of the fingerprint sensor recognition region pressed by the user's fingertip according to the distribution of the fingerprint data by the fingerprint pattern data corresponding to the fingerprint sensor recognition region (S121).

When the position is recognized, the main controller 10 finds a button corresponding to the position recognized in the button region identification table, and recognizes the found button as a pressed button (S123).

When the pressed button is recognized, the main controller 10 executes a button function corresponding to the recognized button (S125).

8 is a flowchart illustrating a fingerprint authentication method of the multifunction input method using the fingerprint sensor of the security token card according to the first embodiment of the present invention.

Referring to FIG. 8, when fingerprint data is acquired (S113), the main controller 10 activates the security controller 50 if it is not activated (S211).

If the security controller 50 is activated, the main controller 10 transmits registration fingerprint data request information to the security controller 50 (S213). The security control unit 50 receiving the registration fingerprint data request information decrypts the registration fingerprint data stored in the secure storage unit 51 when the registration fingerprint data request information is input from the legitimate main control unit 10. Transfer to the main control unit 10. The security control unit 50 has identification information of the main control unit 10 registered in advance, and compares the identification information of the main control unit 10 included in the registered fingerprint data request information with the identification information registered in advance. The validity of the registration fingerprint data request information may be determined. The identification information may be encrypted so that only the main control unit 10 and the security control unit 50 can be known.

After transmission of the fingerprint request information, the main controller 10 monitors whether registration fingerprint data is received from the security controller 50 (S215), and performs fingerprint authentication when registration fingerprint data is received (S217). After performing the fingerprint authentication, it is determined whether the fingerprint authentication succeeds (S219). If the fingerprint authentication is successful, the process S117 of FIG. It may be configured to perform the above-described Figure 7 again from the beginning after the end of the entire process.

9 is a flowchart illustrating a fingerprint authentication method of a multi-function input method using a fingerprint sensor of a security token card according to a second embodiment of the present invention.

9, if the security controller 50 is not activated, the main controller 10 activates it (S311).

If the security control unit 50 is activated, the main control unit 10 transmits fingerprint authentication request information including the fingerprint data obtained by the security control unit 50 to the security control unit 50 (S313).

At this time, the security controller 50 compares the fingerprint data included in the fingerprint authentication request information with the registered fingerprint data previously stored in the security storage unit 51 to perform fingerprint authentication according to whether or not a match exists, and the authentication result is the main controller. Provided by (10). The security controller 50 may minimize the external leakage of the registered fingerprint data since the security control unit 50 uses the registered fingerprint data internally without outputting it to the outside.

After transmitting the fingerprint authentication request information, the main controller 10 checks whether an authentication result is received from the security controller 50 (S315).

When the authentication result is received, the main controller 10 determines whether the authentication is successful (S317). If the authentication is successful, the main controller 10 performs S117 of FIG. 7 and terminates the process if the authentication is successful.
