Description

Password input device and input method using touchpad {PASSWORD INPUT DEVICE USING A TOUCH PAD AND PASSWORD INPUT METHOD OF THE SAME}

The present invention relates to an input device for a digital door lock having a touch pad and an input method thereof. In particular, the present invention relates to a password input device for opening and closing a door such as a front door, a security facility door, a safe, and the like, and a password input method thereof.

The door lock device is provided in the entrance door of a general household, various entrance doors of a company, a store, a public institution, and the door of a safe. The user opens and locks the locked door by entering a preset password. In the past, mechanical door locks have been used, but recently, digital door locks and digital safes with enhanced safety and convenience have been widely used.

The user enters a predetermined password by pressing a key installed on the outside of the door of the door lock housing. In general, however, users tend to use passwords for a long time without changing the password once set. As a result, the user's frequent hand contact causes a problem that the key corresponding to the password becomes dirty, worn, or lost the initial gloss of the product, and thus the password is exposed. Furthermore, it has been pointed out that the problem becomes larger when the input key is made of smooth glossy material, or in the case of a touch pad using a capacitive sensor. As shown in FIG. 6, for example, when the password is “0852”, when the user continuously inputs the input key “0852” to the input key 11 of the touch pad 10 for a long time, a fine trace ( 13) will be produced. Although these minute traces 13 may not be seen at first glance, if you look closely, the traces can be found to recognize the password.

Since the password of the door is the starting point of all security, there has been a need for a technically perfect solution to this problem of the prior art.

As part of such an attempt, Korean Patent Laid-Open Publication No. 2009-41743 discloses a technique of preventing a leak of a password by a fingerprint by distributing fingerprints evenly on a digital door lock keypad by inputting random numbers randomly generated at every input in addition to a password. have. However, according to the prior art of this patent document, there is a problem that a disadvantage arises that the burden has to be burdened every time the user opens the door as a result. That is, each time the door is opened, the user enters a set password, and then enters a random number generated by the door system again, which causes the inconvenience of duplicate input. In the door lock technology, "security" is an important factor, but "fastness" is also a very important factor in terms of door opening and closing, and the patent document ignores this. The user wants to open the door quickly, but since the input action must be repeated for security reasons, there is a delay in opening the door. Therefore, since a method for solving the problem of the password entry mark causes another technical disadvantage, it is not a preferable solution.

The inventor of the present invention has completed the present invention after research efforts to solve these problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of technically completely blocking tracking traces generated by continuous password input and an input device in which the method is implemented.

Another object of the present invention is to realize the above object and to ensure the quickness of opening and closing the door. Therefore, when it comes to speed, there is no big difference compared to the conventional password input method. That is, in addition to the method of inputting the password once by pressing the usual method, the user does not have to perform a separate procedure or action. Therefore, using a plurality of passwords, entering two or more passwords or authentication keys, pressing a normal input key directly, using a separate hardware device that is not familiar to the user, or pressing the password in addition to An approach using the input method of is completely distinct from the present invention, and an object of the present invention is to completely disconnect from such methods.

On the other hand, other unspecified objects of the present invention will be further considered within the range that can be easily inferred from the following detailed description and effects.

In addition, the control unit of the present invention, the module for automatically changing the position of the input point to display on the touch pad when the password input start event of the input start means occurs, a module for detecting the input value of the input point, It is preferable to include a module for mapping the input value and a predetermined password, the module for controlling the operation of the door opening and closing operation unit.

Also, preferably, the input points of the touch pad may be combined with one or more of numbers, letters, symbols, or icons.

A second aspect of the present invention for achieving the object of the present invention, as a password input method using a touchpad:

Generating a password input start event;

When a password input start event occurs, automatically changing positions of input points of the touch pad and expressing the input points on the touch pad at the changed positions;

Through the problem solving means of the present invention as described above, the present invention has the advantage that it is impossible to track the trace generated from the touch pad input point by the hand contact with the user even if using the same password continuously.

In addition, the apparatus and method of the present invention not only prevent the possibility of password leakage due to traces, but also have a remarkable effect of ensuring the promptness of password input.

Although effects not specifically mentioned in the specification of the present invention, it is added that the potential effects expected by the technical features of the present invention are treated as described in the specification of the present invention.

Hereinafter, with reference to the accompanying drawings will be described specific details for the practice of the invention. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured as matters obvious to those skilled in the art, such as related well-known functions, the detailed description thereof will be omitted.

1 shows a schematic configuration of an input device of the present invention. The input device according to the present embodiment includes a touch pad unit including a touch pad 100 and a controller 110 for controlling the operation of the touch pad 100. The input device sets a position value of an input point (not shown) displayed on the touch pad 100 and detects an input value input through the touch pad 100. The input device includes a control unit 200 made of a microcomputer, an input start means 300, a door opening and closing operation unit 400, and a memory 500. In addition, although not shown in the drawing, a power supply unit for supplying driving power is included. The door lock device having the above input device has a predetermined housing fixed at a specific position of the door, and may further include an alarm sound generator or various sensors. In addition, various forms of deformation of the door opening and closing operation unit 400, the detailed configuration of the memory 500, and the specific configuration of the touch pad 100 itself may use various known means, and thus detailed description thereof will be omitted. .

The control unit 200 may include an input point position change module 210, an input value detection module 220, a mapping module 230, and a door operation control module 240. The input point position changing module 210 automatically changes the position value of the input points on the touch pad 100 when the user wants to start inputting a password and displays the changed position on the touch pad 100. The change of position may be random. When the input points of the touch pad 100 are 12, the number of cases that can be changed randomly is 12! = 479,001,600, it is unlikely that the position of the input point will remain at the current position.

Another embodiment of the input point position change module 210 may be disclosed. Since fluctuations in the position values of the input points may cause small confusion for the user upon input, a simplified position value change pattern can be given to minimize this. For example, when a user sets a password and stores it in a memory, the data conversion table may be programmatically organized to create a position value change pattern in order to distribute traces left on the password input point according to the user's password input. In the case of 12 input points of the touch pad 100, since the password is usually made up of four digits, three patterns are created and stored, and “Pattern 1 → Pattern 2 → Pattern 3 → Pattern 1 → Repeat” and the like. You can set the same conversion rule.

Referring to Figure 2, Figure 2 (a) is a pattern 1, Figure 2 (b) is a pattern 2, Figure 2 (c) is a pattern 3. As shown in pattern 1, if the password is "2580", pressing it continuously may leave a predetermined mark only at the corresponding input points. However, if the user wants to open the door again by entering the password, the input point position changing module 210 changes the position of the input points of the password according to the pattern 2. When the next input start event occurs, the input point location change module 210 changes the location of the input points of the password according to pattern 3. As a result, even if the user continues to use the same password without changing it, the traces remaining on the input point can be evenly distributed. In this way, the input point location changing module 210 can change the location of the input points by patterning the number of limited cases, and the pattern is changed by the program of the control unit at the time when the password set by the user is set and stored. Automatically generated.

The input value detection module 220 detects the input password input value when the user inputs a password on the touch pad 100 having the changed input points. The mapping module 230 compares the set password stored in the memory 500 with the detected input value to determine whether the mapping module 230 matches. The door operation control module 240 transmits a control signal to the door opening and closing operation unit 400 when the input value and the set password match, so that the door is opened.

The input initiation means 300 generates an input initiation event. As the input start event is transmitted to the control unit 200, the input point position changing module 210 of the control unit 200 automatically changes the position of the input point of the touch pad 100. The input start event may occur in various forms. This depends on various hardware and / or software variations of the input initiation means 300. For example, if the door device housing has a cover, and the touchpad 100 is opened only by opening the cover, the opening of the cover may be recognized as a time when a user enters a password to open the door. Therefore, in this embodiment, the cover serves as an input start means, and the control unit 200 determines whether the cover is opened and, when the cover is opened, recognizes that an input start event has occurred, and then inputs the input point position change module 210. It can work.

In addition, another variation of the input initiation means 300 may be a button provided in the door apparatus housing. This button may be a mechanical button or an electronic button that senses whether or not a user's hand touch is pressed. In this embodiment, the user sets a password after pressing the corresponding button. Therefore, in the present embodiment, the button is provided in the housing of the door apparatus, and the control unit 200 determines whether the button is pressed, and if the button is pressed, recognizes that an input start event has occurred and recognizes that an input start event has occurred. 210 can be operated.

In addition, another variation of the input start means 300 may be any one of “*”, “#” of the input points of the touch pad 100, or numbers, letters, and icons visually displayed on the touch pad. Input points of the touch pad 100 are generally provided with "*" and "#", and usually the former generates a password input start and the latter generates a signal of password input end. Therefore, in the present invention, among the input points of the touch pad 100, “*” may be the input start means 300. In addition, “#” may be an input start means, since it may be easily modified depending on how to set in the microcomputer. In addition, it may be a specific number of the touch pad 100 from the same point of view. In addition, the value and arrangement of the input points set on the touch pad 100 are generally composed of numbers and symbols (*, #), as shown in FIG. There is no technical difficulty in displaying. Therefore, in this case, the input start means 300 may be numbers, letters, or icons that are visually displayed on the touch pad.

In addition, another variation of the input initiation means 300 may be a means for recognizing a user's hand contact applied to the touch pad. For example, when the user sweeps the surface of the touch pad by hand, the user's hand touch is sensed to express an input point of the touch pad and wait for a password input. Accordingly, in the present embodiment, the input initiation means 300 is a means for recognizing a user's hand contact, and the control unit 200 determines whether the user's hand is swept over the touch pad 100, and the user When the hand contact is recognized, it may be determined that an input start event has occurred to operate the input point position change module 210.

3 illustrates the entire process of a password input method using a touch pad according to the present invention. When the input start means generates a password input start event by the various modifications described above (S10), the input point position changing module of the control unit automatically changes the positions of the input points of the touch pad to change the input points to the changed positions. It is displayed on the touch pad (S11). Preferably, the positions of the input points can be randomly changed. A change in the random manner is shown in FIGS. 4 and 5. FIG. 5 shows an example of a change when an input start event following the change of FIG. 4 occurs. More preferably, the position change can be patterned and the position of the input points can be changed in accordance with the pattern. In addition, other methods can be used to automatically change the position of the input points. This is illustrated in FIG. 2.

Next, the input point detection module of the control unit detects an input point input through the touch pad, that is, a password input by the user (S30). The detected input point and the preset password are mapped, that is, compared to determine whether they match (S13). When the detected input point and the preset password coincide, the door is opened by commanding the opening operation of the door opening / closing operation unit (S14).

In the present specification, the input points of the touch pad have been described based on a combination of numbers and symbols (*, #). However, since the touch pad input system is generally selected in the industry, the input points of the touch pad are described based on the convenience. It's just that. The input point of the touch pad may be composed of text or other symbols or icons. Including an icon shaped as an image at the input point can emphasize the visual impact of the touchpad. Therefore, it may be understood that the input point of the touch pad of the present invention is combined with one or more of numbers, letters, symbols, or icons.

On the other hand, the scope of protection of the present invention is not limited by the embodiments explicitly described above. Further, it should be noted that the protection scope of the present invention may not be limited due to obvious changes or substitutions in the technical field to which the present invention belongs.
