At this time, the position pattern may be a combination of these specific points. Otherwise, the position pattern may be a pattern of continuous lines drawn by the user on the touch panel.

The pressure pattern may be formed by stepping the pressure applied to points on the input pad corresponding to the position pattern. For example, when a user sets a combination of numbers as a position pattern, the degree of pressure applied to points corresponding to the numbers can be respectively set. The degree of this pressure may be set to a strong pressure and a weak pressure, or may be set to be subdivided in stages.

The coordinate processing unit 130 calculates the coordinates of the point where the pointing object is touched based on the input to the input pad 120.

For example, the touch pressure sensor 145 may be disposed in a plate form. As will be described in detail below with reference to FIGS. 4 and 5, the points on the input pad 120 constituting the position pattern may be randomly arranged in the arrangement. In addition, the arrangement of points on the input pad 120 constituting the position pattern can also be arranged at random. In this manner, the security of the password can be further enhanced by randomly setting the arrangement and arrangement of the input points on the input pad 120.

4 is a diagram illustrating an exemplary arrangement of input points.

As shown, the arrangement of points on the touch panel constituting the position pattern can be set at random. For example, when setting the position pattern as a password, the user may set the (4 X 3) arrangement as the input pad 410 or the (6 X 2) arrangement as the input pad 420 .

In one embodiment, even if the user activates the input pad 420 for user authentication, the touch panel may not display any characters, and the user may set the points on the preset input pad 420 at a preset pressure intensity You can enter your password by contacting. As described above, since the user authentication can be performed by touching the position stored by the user without performing any display on the input pad 420, the password security can be further enhanced. In addition, the arrangement of the input points on the input pad 420 can also be set to various arrangements such as (6 X 2), (3 X 4), etc., as well as a universal (4 X 3) Security can be further enhanced.

Alternatively, the arrangement or arrangement of the position patterns may be set randomly, such as with the input pad 520. In this manner, since the position of the input points as well as the character itself of the password is also a condition of the password, the number of cases of the password increases so much that the security of the password can be further strengthened.

Also, although not shown, the security control apparatus according to embodiments of the present invention may further include a separate button allocated to the position pattern. These separate buttons may be disposed on the upper or lower side or the left and right of the input pad. For example, when setting a position pattern as a password, the user may combine the above-described separate buttons with points on the input pad.

FIG. 6 is a diagram showing an example of operating the security control apparatus of FIG. 1;

As shown in FIG. 6, touch pressure sensors may be disposed on the rear surface of the input pad 210 at positions corresponding to specific areas on the input pad 210. 3 to 5, a touch pressure sensor may be assigned for all the coordinate values on the input pad 210, and when the user sets the position pattern as a password, The pattern can be set as shown in Fig. According to an embodiment, the position of the touch pressure sensors disposed on the rear surface of the input pad 210 may be displayed or may not be displayed. Hereinafter, an example of a method of inputting a password to the input pad 210 will be described.

For example, when a user sets a password, the position pattern is set in the order of "top left - center bottom - right bottom - right top" and the pressure pattern is set to "contact strength 3 - contact strength 1 - contact intensity 2 - contact intensity 1 ". The user may touch the finger with a pressure of "contact strength 3" at the upper left of the input pad 210 (first input; 220) for user authentication. Thereafter, the user may sequentially perform the second input 230 to the fourth input 250. As described above, according to the security control method according to the embodiments of the present invention, not only the position of the contact applied to the input pad 120 but also the strength of the contact are detected at the same time so that a trace remains on the input pad 120, Even if the process is exposed, it is possible to prevent analogy or exposure of the password.

Referring to FIG. 7, the user can set a position pattern and a pressure pattern as a password (S10). Next, the input of the pointing object is received through the input pad (S20). Thereafter, the coordinates of the point at which the pointing object is touched based on the input through the input pad are calculated (S30), and the contact strength at the point where the pointing object is touched is measured (S40). Next, the opening and closing of the door is controlled by comparing the coordinates of the contact point and the contact strength with the preset position pattern and the pressure pattern, respectively (S50).
