Description
The present invention relates to a password input system and method.
With the recent increase in the use of unattended ATMs and the active activation of Internet banking and mobile banking using smartphones, tablet computers, PCs, etc., individuals are required to enter passwords for personal identification in public places. It was. Nevertheless, the conventional password input method using a keyboard records a keylogging attack in which a user records button information and finds out a password, or shoulder surfing that finds and looks at a user's password behind a user's shoulder. Shoulder Surfing) has the disadvantage of being very vulnerable to attack. In particular, if a user repeatedly enters the same password, it is highly likely to be exposed to such risks. As described above, many techniques for reinforcing safety in case of repeatedly inputting a password have been proposed. However, even when the input speed is high, the input speed is very slow because the key input time is about 10 seconds.
Therefore, while using the existing password input authentication method using a personal identification number (PIN), a password input system having a fast input speed that not only enhances stability but also requires a key input time of less than 5 seconds is required.
In this regard, Korean Patent Laid-Open Publication No. 2007-0044916 (name of the invention: a method for inputting a password for a mobile communication terminal) includes inputting a password, selecting and storing an input location keypad number, a location corresponding to the input location keypad number. A method of inputting a password includes moving a direction key to map a password number among randomly arranged numbers, and inputting the same using a selected special key.
The present invention is to solve the above-mentioned problems of the prior art, some embodiments of the present invention can enhance the safety while using the existing password input authentication method using the existing PIN, and can also improve the key input speed than the existing It is an object of the present invention to provide a password input system and method.
As a technical means for achieving the above technical problem, the password input system according to the first aspect of the present invention is arranged to output a plurality of random keypad in the keypad interface according to a preset layout, each random keypad is randomly arranged A plurality of character keys, each character key included in each random keypad is a keypad output unit arranged to correspond one-to-one with the plurality of random keypads according to the layout, a password storage unit in which a preset password is stored, a user's random keypad A decryption unit for decrypting a character key corresponding to the input random keypad position into a user input password based on a state of the arrangement of the character keys of the random keypad under preset conditions, the preset password and the input password It includes a comparison unit for comparing the.
In addition, the password input method using a password input system according to a second aspect of the present invention comprises the steps of arranging and outputting a plurality of random keypad in the keypad interface according to a predetermined layout, each letter key included in each random keypad to the layout Disposing one-to-one correspondence with the plurality of random keypads according to the user; when a random keypad input of the user occurs, based on a state of arrangement of the character keys of the random keypad under a preset condition, a character key corresponding to the position of the input random keypad And decrypting the input password of the user, comparing the preset password with the input password, wherein the random keypad includes a plurality of randomly arranged character keys.
According to one embodiment of the above-described problem solving means of the present invention, by entering the temporary password generated through the random keypad on the plurality of random keypads without exposing the password set by the user to the outside, security and convenience is improved In addition, the input speed can be improved.

Meanwhile, the preset layout may be arranged in the same manner as the 3 * 4 numeric key button used in the mobile phone or the ATM. However, in the password input system according to the present invention, the layout of the plurality of random keypads and the plurality of character keys included in the plurality of random keypads may be arranged in a different arrangement as well as an arrangement of 3 * 4.
Each random keypad on the keypad interface includes a plurality of randomly placed character keys. In addition, each character key included in each random keypad is arranged to correspond one-to-one with a plurality of random keypads according to a layout. Referring to FIG. 3, a plurality of random keypads are arranged in an array of 3 * 4 on a keypad interface, and a plurality of character keys are included on each random keypad. Accordingly, the user selects one random keypad among the plurality of random keypads, inputs a plurality of random keypads as key buttons by designating a character key displayed on the selected random keypad as a password.
In addition, referring to FIG. 2, a method of inputting a plurality of random keypads as a key button is as follows. A plurality of random keypads are output on the keypad interface, and each of the plurality of random keypads is one key button. Therefore, when the user inputs the
Next, a random keypad having different colors on the keypad output unit will be described with reference to FIG. 3.

On the other hand, the colors displayed on the plurality of random keypads are displayed at random. In other words, since there is no specific rule for selecting a color, a specific color cannot be continuously assigned to the same position, thereby preventing a password from being exposed to the outside.
Referring back to FIG. 1, the
When the key input occurs on the
Referring to Figure 4 describes the process of decrypting the input password as follows. First, the preset password is called '1234'. The random keypad including the preset password is selected according to a preset condition among the plurality of random keypads. A method of selecting a random keypad according to a preset condition is as described above with reference to FIG. 3. When the

In the password input method using the password input system according to the present invention, first, a plurality of random keypads are arranged in the keypad interface according to a preset layout and output (S610).
In this case, the plurality of random keypads may be output in different colors, and the random keypad may be selected by designating a random keypad having a color preset by the user as a preset condition among the plurality of random keypads.
Also, by specifying a randomly selected color among a plurality of random keypads as a preset condition and outputting the selected color as a voice, the user can listen to the voice output and select a random keypad.
Next, each character key included in each random keypad is arranged to correspond one-to-one with the plurality of random keypads according to the layout (S620). For example, referring to FIG. 3, the plurality of random keypads corresponding to the first letter key '5' on the first random keypad becomes the first
Next, when the user's random keypad input occurs (S630), based on the state of the character key arrangement of the random keypad under a predetermined condition, the character key corresponding to the position of the input random keypad is decoded by the user's input password ( S640). For example, referring to FIGS. 3 and 5, the user checks the position of the preset password '1234' on the
Next, the preset password and the input password is compared (S650). Since the decrypted password as the input password is' 1234, the password is matched with the previously stored password '1234' to check whether the password match.
The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
