As smart devices such as smart phones and tablets have become widespread, mobile banking systems using them have been widely used. The existing mobile banking system performs login by inputting a user's authorized certificate or an ID and password. When a user requests a transaction such as a money transfer, the mobile banking system provides a credit card or an OTP device So that the authentication process must be performed.

Here, the security card is a physical means configured separately from the smart device, and is a card composed of four-digit serial numbers from 1 to 35 respectively. In mobile banking, the authentication server provides the numeric location of the serial number to be filled in, and the user proceeds authentication by directly writing the serial number of the corresponding location through the mobile. At this time, the security card is usually carried by a user in a purse, taken out of the purse whenever necessary, and used the serial numbers described in the security card for authentication. Accordingly, the users use the security card by photographing the security card, storing the image in the form of an image in the smart device, and inquiring the stored image whenever necessary.

As described above, the mobile banking service using the security card has an inconvenience that the user must confirm the security card while holding it. In addition, when an authentication number is input while viewing a physical security card or a security card image at a place where a user is exposed, a surrounding person can easily check the security card information, and there is a high possibility that the security card information is exposed to the outside .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is also referred to as "including" an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated to the contrary.

First, the meaning of the terms used below is defined.

The term " security card " is a card including numbers necessary for transaction authentication through a financial institution, and includes a plurality of serial numbers each of which is composed of four or more digits.

The 'security card serial number' means a combination of four or more digits included in the security card, and each security card serial number includes the sequence number and digits (for example, the front two digits and the back two digits) .

The 'security card password' is a combination of numbers contained in different serial numbers included in the security card, which is information required by a financial institution for transaction authentication. For example, the combination of the last two digits of the first serial number and the preceding digits of the 13th serial number can be the security card password.

The 'security card password location information' is information on locations where the numbers constituting the security card password are arranged on the security card. For example, in the above example, the back two digits of the first serial number and the first two digits of the thirteenth serial number correspond to the security card password position information.

The 'security keypad' refers to the input interface provided to display the security card password to the user and to receive the password.

In the following description, the account password of the user does not necessarily have to be the password of the actual account but may be an arbitrary password preset by the user.

Hereinafter, a system for inputting a security card password according to an embodiment of the present invention will be described in detail with reference to FIG.

The system of one embodiment of the present invention includes a client terminal 100, an authentication server 200, and a secure card server 300. [

The client terminal 100 is preferably a portable terminal such as a smart phone, a tablet PC, a notebook, or the like, but this is merely an example, and may be configured as a terminal such as a desktop in some cases. The authentication server 200 may be a server of a financial institution that performs an authentication process when Internet banking including a transfer of money, an account inquiry, and the like proceeds through the client terminal 100. The secure card server 300 is a server that stores security card information of users (for example, information including security card serial numbers and security card identification numbers included in a security card). In the figure, although the secure card server 300 and the authentication server 200 are shown as separate components, the two servers 200 and 300 may be integrated into one server. The client terminal 100, the authentication server 200, and the secure card server 300 may communicate with each other via a wireless or wired network.

When the user writes the transaction information including the account password and the transfer amount in the client terminal 100, the authentication server 200 can receive the security card password input request. At this time, the client terminal 100 transmits a security card password position information request to the authentication server 200. [

Next, the client terminal 100 receives the security card password location information from the authentication server 200 and transmits it to the secure card server 300. The secure card server 300 can extract the secure card password from the user's secure card information stored in the secure card server 300 by referring to the received secure card password location information. Then, the secure card server 300 transmits the secure card password to the client terminal 100. [

Here, instead of receiving the secure card password from the secure card server 300, the client terminal 100 stores the secure card information of the user in the client terminal 100 itself, refers to the secure card password location information, May be extracted or confirmed.

The client terminal 100 generates a security keypad based on the security card password and the account password of the user, and provides the security keypad to the user. Here, the user confirms the number of the area corresponding to the account password through the security keypad, inputs the confirmed number as the security card password through the input keypad included in the security keypad, and the client terminal 100 accesses the security keypad And sends the password of the security card inputted by the user to the authentication server 200 to request authentication.

In the authentication process according to the embodiment of the present invention, if the user knows only the account password without holding or checking the physical security card through the security keypad, the user can easily input the password of the security card, .

Hereinafter, the structure of the client terminal 100 according to an embodiment of the present invention will be described in detail with reference to FIG. The client terminal 100 includes a security card password input program and may be referred to as a security card password input device. The security card password input program may be a program that is loaded in the financial institution transaction application installed in the client terminal 100 and is called whenever the security card password authentication is required as the transaction information is input from the user. Alternatively, the security card password input program may be an application installed in the client terminal 100 separately from the financial institution transaction application, and may be an application that is called whenever authentication is required.

The client terminal 100 includes a secure card password location information requesting unit 110, a secure card password extracting unit 120, a security keypad providing unit 130 and an authentication requesting unit 140. The configurations 110 to 140 may be implemented in the computer readable recording medium of the client terminal 100 as the secure card password input program is installed in the client terminal 100. [

The secure card password location information requesting unit 110 requests and receives the secure card password location information from the authentication server 200. [ When the transaction information including the account password and the transfer amount is input from the user to the financial institution transaction application of the client terminal 100 before the security card password position information is requested, the client terminal 100 transmits the transaction information to the authentication server To the authentication server 200, and receive a security card password authentication request from the authentication server 200. [ Upon receipt of the security card password authentication request, the security card password input program is invoked and executed, and the security card password location information requesting unit 110 can transmit the security card password location information request to the authentication server 200. [

The security card password extraction unit 120 extracts the security card password by referring to the received security card password location information. Specifically, the secure card password location information and user information are transmitted to the secure card server 300. The secure card server 300 retrieves the secure card information corresponding to the received user information among the stored secure card information. The secure card server 300 transmits a combination of numbers corresponding to the secure card password location information among the secure card serial numbers included in the secure card information to the client terminal 100 as a secure card password. The secure card password extracting unit 120 receives the secure card password from the secure card server 300. [

As described above, the security card password may be obtained by storing the user's security card information in the client terminal 100 instead of using the secure card server 300, and acquiring the security card information. In this case, the security card password extracting unit 120 can check the security card password from the security card information of the user stored in the client terminal 100 by referring to the received security card password location information. Here, the security card information may be stored in an application such as an electronic wallet to the client terminal 100, or may be manually entered and saved by the user or extracted and stored in the security card image.

The security keypad supplier 130 provides a security keypad M, which is an input interface for requesting a user to input a security card password. 3A, the security keypad M may be composed of a plurality of subkeypads S1 to S4, and each of the subkeypads S1 to S4 may include a plurality of first integers I1 and a plurality of A second constant I2 and a special symbol. The first and second constants I1 and I2 may be constants of 0 to 9 that do not overlap with each other, . And one second constant I2 may correspond to one first constant I1. The first integer I1 is arranged in the order from the top to the bottom of the first subkeypad S1 in order of magnitude (i.e., in the order of 1, 2, 3, ... 8, 9) except 0, (I2) may be arranged in any order (i.e., randomly). The arrangement combination of the plurality of second constants I2 may be set to be different for each of the sub keypads S1 to S4.

In the keypad described below, the first integers I1 are arranged on the keypad in the order of magnitude as described above, and thus may not be displayed on the keypad but may be omitted. In the following description, it is assumed that each keypad includes a first integer I1 for convenience of explanation.

Each of the sub keypads S1 to S4 serves to display one of several numbers constituting the security card password to the user. Although only the first to fourth sub keypads S1 to S4 are shown in FIG. 3A, four or more sub keypads may be configured according to the number of digits of the secret card password.

3A, the security keypad M may be implemented such that a plurality of sub keypads S1 to S4 are displayed in the screen of the client terminal 100. However, as shown in FIG. 3B, the security keypad M may include one subkeypad S1 To S4 may be displayed on one screen of the client terminal 100. For example, when the first sub keypad S1 is displayed on the one screen of the client terminal 100 and then the first sub keypad S2 is displayed when the first secret card password is input, One sub keypad (S1 to S4) may be provided sequentially in accordance with the step of inputting the password.

What is important here is that the security card password is placed at a position of the first integer I1 equal to the user's account password and the corresponding second integer I2. For example, if the security card password is set to 27, which is the first two digits of the 12th serial number of the security card, and 68, which is the back two digits of the 04th serial number of the security card, and the security card password is "2768" It is assumed that the password is "1234 ". Referring to FIG. 4A, it can be seen that 2, 7, 6, and 8 are arranged in the positions of the second integers I2 corresponding to the numbers 1, 2, 3, and 4 among the first integers I1 . That is, when the user identifies the account password and inputs the second integers I2 corresponding to 1, 2, 3, and 4 corresponding to the account password, even if the user does not know how the security card password is configured, The card passwords 2, 7, 6, and 8 are input. As another example, it is assumed that the security card password is "9138" and the account password of the user is "3587". Referring to FIG. 4B, it can be seen that the security card passwords 9, 1, 3, and 8 are disposed at the positions of the second integer I2 corresponding to the account passwords 3, 5, 8, and 7 of the user. The security keypad provider 130 may extract the account password of the user by using the transaction information input by the user or receiving the transaction information from the authentication server 200 and may receive the password from the secure card server 300, The security keypad M can be generated using the security card password confirmed from the security card information stored in the security keypad 100. [

Here, it is assumed that the user's account password and the digits (for example, four digits) of the security card password are the same. The first integer I1 corresponding to the account password and the second integer I2 referring to the security card password correspond to the input order of numbers constituting the account password and the order of inputting numbers constituting the security card password They can be arranged to correspond to each other. For example, if the account password is configured to have an input order of 1-> 2-> 3-> 4 and the security card password is configured to have an input order of 2-> 7->> 6-> 8, Quot; 2 "is assigned as the second integer I2 corresponding to the first integer I1 in the sub keypad S1 and the second integer I2 in the second sub keypad S2 is allocated as the second integer I2 corresponding to &Quot; 6 "is assigned as the second integer I2 corresponding to" 3 ", which is the first integer I1 in the third sub keypad S3, Quot; 8 "may be arranged as a second integer I2 corresponding to" 4 ", which is the first integer I1 in the fourth sub keypad S4. At this time, the arrangement of the plurality of second constants I2 is arranged in a different order for each of the sub keypads S1 to S4, and among the second constants I2 in the sub keypads S1 to S4, 2 ", "7 "," 6 ", and "8" corresponding to the card password.

Meanwhile, a security keypad M according to another embodiment of the present invention may be provided. 5A, the security keypad M may include a first keypad image T1, a second keypad image providing button T2, and an input keypad T3. The first keypad image T1 is configured to have a plurality of subkeypad S1 through S4 images wherein each subkeypad S1 through S4 image comprises only a plurality of first integers and a plurality Lt; RTI ID = 0.0 > a < / RTI > Or may be configured to provide a space at a position of a plurality of second integers corresponding to the plurality of first integers, without including a plurality of first integers. That is, the security keypad M of FIG. 3A may have a shape in which spaces are provided at positions of a plurality of second integers.

Then, when a user input to the second keypad image providing button T2 is generated, a second keypad image T4 as shown in FIG. 5B may be provided. The second keypad image T4 may be provided in a shape having the same numerical arrangement structure as the security keypad M described with reference to FIG. 3A. That is, the second keypad image T4 displays the security card password at the position of the second integer corresponding to the first integer corresponding to the user's account password, and the position of the second integer other than the area where the security card password is displayed Lt; RTI ID = 0.0 > a < / RTI > integer combination arranged in any order.

The user can identify the security card password from the position of the second integer corresponding to the account password in the second keypad image T4.

Here, the user can input the security card password identified as above through the input keypad T3. It is preferable that the security card password identified here is inputted through the input keypad T3 instead of the second keypad image T4. This is because when the security card password is input through the second keypad image T4, the account password of the user can be exposed to the outside.

Meanwhile, the security keypad M according to an embodiment of the present invention is not limited to the shapes and structures as shown in FIG. 3A, FIG. 3B, FIG. 5A, and FIG. 5B, and may be configured as a dial pad type, .

The authentication request unit 140 transmits the security card password input by the user via the security keypad M to the authentication server 200 to request authentication.

The client terminal 100 requests the security server password location information to the authentication server 200 in step S102 and the authentication server 200 transmits the security card password location information to the client terminal 100 in response to the request S103).

Then, the client terminal 100 transmits the user information and the security card password location information to the secure card server 300 (S104).

The secure card server 300 is a server that holds security card information of each user, and can retrieve the security card information of the user based on the received user information (S105).

Then, the secure card server 300 can extract the secure card password from the secure card information by referring to the secure card password location information (S106).

The client terminal 100 receives the security card password from the secure card server 300 (S107).

Here, steps S104 to S107 may be omitted when the security card information of the user is stored in the client terminal 100 as described above. In this case, the security card password can be extracted from the stored security card information by referring to the security card password location information.

The client terminal 100 may generate the security keypad M based on the security card password and the account password and provide the security keypad M to the user (S108). The security keypad M includes a plurality of first integers and a plurality of second integers disposed at positions corresponding to the first integers. The security keypad M is a security card password input interface that allows a user to easily and safely input a security card password do. Here, the first integer may be omitted and may be composed of only the second integer, if necessary. At this time, the security card password is placed at the position of the second integer corresponding to the first integer, which is the same as the account password of the user. At this time, the user can confirm the second integer corresponding to the account password and input the security card password using the input keypad included in the security keypad. Since the security keypad M provides the security card password that can be identified only by the user and does not directly provide the security card information, it is possible to prevent information leakage or disclosure by the surrounding persons.

The client terminal 100 transmits the security card password inputted by the user to the security keypad M to the authentication server 200 (S109).

The authentication server 200 receives the transaction information from the client terminal 100 and compares the security card password generated in advance near the time point when the client terminal 100 requests the security card password input and the security card password received in step S109 And performs authentication (S110). After authentication, the user can complete the requested transaction (for example, transfer of funds, inquiry, payment, etc.).
