It is to be understood that the term 'comprises', 'haves', 'comprises', 'comprises', etc., in the present specification does not preclude the existence or addition of one or more other features or components or combinations thereof in advance. .

In the present invention, a mobile or a mobile terminal refers to an electronic device that can be connected to a network through a wireless Internet or the like through a mobile application such as a smartphone or a tablet PC. In addition, in the present invention, the secret code refers to a code or a symbol relating to identification, verification, or authentication that must be treated or need to be treated as confidential on the network or when connected to the network. Preferably, a password or a password is mentioned.

The input of the secret code in the present invention includes both the input in the process of generating the secret code and the input in the process of confirming the secret code.

First, specific embodiments of the secret code input devices in the mobile terminal of the present invention will be described with reference to FIGS. 1 to 4. 1 to 4 may be provided with various functions, and according to the difference in the implementation function, it is possible to change to various embodiments.

1 is a block diagram schematically illustrating a secret code input device in a mobile terminal according to an embodiment of the present invention, and FIG. 2 is a secret code input device in a mobile terminal according to another embodiment of the present invention. Figure 3 is a block diagram schematically showing, Figure 3 is a block diagram schematically showing a secret code input device in a mobile terminal according to another embodiment of the present invention, Figure 4 is another embodiment of the present invention A block diagram schematically illustrating a secret code input device in a mobile terminal according to an example.

Referring to FIG. 1, referring to one embodiment of the present invention, a password input device in a mobile terminal includes a DB module 110, a block module 120, an input module 140, and a control module 130. It is done by 2 to 4, the control module 130 of FIG. 1 includes a code set generation module 131 and a default processing module 133. That is, the functions performed by the control module 130 of FIG. 1 may be performed in the code set generation module 131 and the default processing module 133 in FIGS. 2 to 4.

First, in FIGS. 1 to 4, the DB module 110 stores at least one or more sets including at least a number set among a number set, an English character set, a special symbol set, and a Korean character set. Preferably, the Korean character set may include a consonant set and a vowel set separately, and the alphabet set and the consonant set and the vowel set of the Korean character may be a mixed set in which alphabets and Korean characters (consonants or vowels) may be selected. . The special symbol set includes special symbols that can be written on the keyboard of a mobile device. Preferably, the DB module 110 is embedded in each mobile terminal in the form of a library as the application is installed. In addition, it is also possible that the DB module 110 is provided from a server (not shown) in the form of an application. In this case, the DB module 110 shown in FIGS. 1 to 4 is connected to a server (not shown). It is understood to mean a module that retrieves data stored from. Hereinafter, the term 'set' in the present specification means a number set, an English character set, a special symbol set, or a Korean character set stored in the DB module 110 unless there is a conflict in the overall meaning.

1 to 4, the block module 120 generates a block corresponding to a plurality of digits for forming a secret code. For example, the number of digits may include four or six digits that are generally used as passwords in the financial sector, or at least six or eight digits of the network access password, and may be fixed, for example, up to sixteen digits. As the blocks of the respective positions are rotated, the block module 120 cycles the numbers, letters or symbols belonging to the set arranged in each block, and stops them and displays them on the blocks. Preferably, each block is configured such that each set is circulated in a virtual chain-like format, for example, one number or letter belonging to each set is displayed on the block. Rotating a block in the present invention does not actually rotate the block, but means that a set placed on the block, such as a set of numbers, a character set, a special symbol set, etc., rotates and rotates on the block.

1 to 4, the input module 140 receives a combination code of numbers, letters, or symbols displayed on each block by the block module 120 as a secret code. The input method will be described in detail later.

Next, look at the control module 130 of FIG. In this case, the function of the control module 130 may be variously implemented according to embodiments. In one embodiment, the control module 130 retrieves each set stored in the DB module 110 and places them in the block generated by the block module 120. At this time, for security purposes, a spacer is inserted at a position corresponding to a sequence of random numbers received and decrypted from the server in each set arranged in the block. In addition, the control module 130 defaults and transmits the secret code received from the input module 140.

According to the present invention, a combined code and a spacer displayed on a block and input by a secret code by the input module 140 are selected after being inserted into a spacer and then processed by default. Can be different. For example, after arranging a list of a set of DB modules 110 in order, a spacer is inserted at a position corresponding to a sequence of random numbers received from a server (not shown), and then the rest of the list of the set continues. By completing the set displayed on the block in a populated manner, the value entered by the mobile user differs from the default transmitted value, making it difficult to guess the secret code even if an attacker hacks the transmitted value. For example, in each block, if the display value of the selected number, letter or code is equal to or larger than the order value of the decoded random number received from the server, the default value actually transmitted is received by the input module 140. Since it is displayed and inconsistent with the selected value, even if it is exposed to the outside by hacking during the transmission process, it is possible to prevent the correct password from being found. On the other hand, since the server stores the encrypted random number transmitted to the mobile terminal, it is possible to interpret the correct secret code by excluding the spacer in the order of the random numbers inversely to the value received from the mobile.

Specifically, for example, the case of entering a secret code in a set of numbers. In the case of entering a four-digit password in a set of numbers from 0 to 9, a random number [0,3,1,7] is received from a server, and the user can receive a number [3,2, 1,7] as the password value. At this time, '3' displayed in the first block is the fourth number in the number set from 0 to 9, but since the first value of the random number received is '0', the spacer is inserted in the first position of the number set circulating in the first block. As a result, the displayed number '3' input by the user is substantially the fifth pushed-out value. Accordingly, if the input number '3' is processed by default, it is recognized as the fifth number in the set of numbers, and the fifth number in the number set is '4'. In addition, the number '2' input by the user as the second digit of the password is the third number of the set of numbers, while the second value of the random number is '3' and the spacer is inserted in the fourth digit. Since the number '2' which is selectively input still occupies the third digit, the same value of '2' is transmitted when it is transmitted by default. Similarly, the third value '1' of the password entered by the user is originally the second digit, but the third value of the random number '1' is also the second value of the number set, so a space is inserted in the second digit of the number set circulating on the block. The actual displayed number '1' defaults to the third number. The last value entered by the user, '7', is likewise sent to the value '8' when processed by default. As a result, the numeric value transmitted to the server (not shown) becomes [4,2,2,8] instead of [3,2,1,7] input by the user. The server compares the value of each digit of the password input from the mobile terminal with the value of each digit of the transmitted random number, and if the input value is larger, the user inputs the password by performing the operation 'input value-1'. You can check.

In the above description, the number set is described as an example. However, in the case of the alphabet set, the special symbol set, and the Korean character set, the order is determined in advance, and thus, the same may be applied as the number set.

More specifically, with reference to Figures 2 to 4, looks at the embodiments of the password input device in the mobile terminal. 2 to 4, the functions performed by the control module 130 of FIG. 1 are performed by the code set generation module 131 and the default processing module 133 in FIGS. 2 to 4. More preferably, the control module 130 of FIG. 1 further includes the code set changing module 135 of FIGS. 3 and 4.

2 to 4, the code set generation module 131 loads each set stored in the DB module 110 and places them in the block generated by the block module 120. The code set generation module 131 allows a spacer to be inserted at a position corresponding to a sequence of random numbers received and decrypted from a server (not shown) in each set arranged in a block for security. The random number is provided from a server (not shown), and preferably, although not explicitly shown in FIG. 4, the random number is decoded by the encryption / decryption module 150 and then provided to the code set generation module 131.

2 to 4, the default processing module 133 defaults and transmits the secret code received from the input module 140.

Preferably, according to one embodiment, each set of spacers inserted by the control module 130, preferably by the code set generation module 131, is circulated or stopped by the block module 120 on the block. The spacer is not displayed. In short, the state where the spacer is inserted cannot be confirmed on the screen. Accordingly, even if the display state is hacked from the outside, even if the spacer is added to each set of the digits of the secret code received by the input module 140, it is impossible to know, and the security is enhanced.

In addition, the password input device in a mobile terminal according to another aspect of the present invention, as in the previous embodiment, the DB module 110, block module 120, input module 140 and control module 130 ) At this time, the control module 130 is different from the previous embodiment in its function.

First, the DB module 110 stores at least one or more sets including at least a number set among a number set, an English character set, a special symbol set, and a Korean character set, and the block module 120 includes a plurality of sets of secret codes. A block corresponding to the number of digits is generated, and as the block of each digit is rotated, numbers, letters or signs belonging to the set arranged in each block are cycled and displayed on the block. In addition, the input module 140 receives a combination code of numbers, letters, or symbols displayed on each block by the block module 120 as a secret code.

The control module 130 retrieves each set stored in the DB module 110 and places the blocks in the block generated by the block module 120. And, unlike in the previous embodiment, the control module 130 is a sequence of random numbers received and decrypted from a server (not shown) within each set of digits of the secret code received from the input module 140 for security purposes. Insert the spacer at the position corresponding to the value and insert the spacer and transmit the default value corresponding to the above-mentioned input password.

In the present embodiment, the description of the default processing by inserting the spacers at positions corresponding to the order of the random numbers in the control module 130 may be apparent to those skilled in the art from those described in the above embodiments.

2 to 4, referring to another embodiment, the control module 130 having a different function includes a code set generation module 131 and a default processing module 133.

According to one embodiment, the code set generation module 131 in FIGS. 2 to 4 retrieves each set stored in the DB module 110 and places them in the block generated by the block module 120.

On the other hand, as a characteristic in comparison with the above-described embodiment, the default processing module 133 is received from a server (not shown) in each set of digits of the secret code input from the input module 140 for security purposes. The spacer is inserted at a position corresponding to the sequence of the decoded random numbers, and after inserting the spacer, the value corresponding to the input secret code described above is processed by default and transmitted. In this case, the random number is provided from a server (not shown), and is preferably provided to the default processing module 133 after decrypting in the encryption / decryption module 150 as shown in FIG. 4.

In the present embodiment, the description of the default processing by inserting the spacers at positions corresponding to the order of the random numbers in the default processing module 133 is performed by inserting the spacers by the code set generation module 131 described in the previous embodiment. It will be apparent to those skilled in the art from the processing.

Preferably, another embodiment of the present invention will be described with reference to FIGS. 3 and 4.

3 and 4, in one embodiment of the password input device in the mobile terminal, the control module 130 further comprises a code set changing module 135 in the foregoing embodiments. The code set changing module 135 in the present embodiment converts the set arranged in the block by the code set generating module 131 into another set stored in the DB module 110 according to the setting input. Accordingly, the setting of the code set can be changed or stored according to the taste of the mobile user. For example, a password required for network access or the like may be generated by combining not only numbers but also English characters, and the user may select a different set such as a number set or an English character set even if a set on a block corresponding to each digit of the password is initially determined. It becomes possible.

Even if the code set changing module 135 is provided in the present embodiment, the code set changing module 135 is used for the management of a secret code in a server (not shown) that provides an application, for example, in the case of inputting an account password of a financial institution. ) Can be disabled. Of course, it is also possible at this time to shift the position order of the blocks as described below. This is because the order of the blocks can be changed so that the desired number or letter can be placed where the user wants.

Preferably, according to another embodiment of the present invention, in the embodiment of the password input device in the mobile terminal according to Figures 1 to 4, the rotation of the block in the block module 120 is a touch on the block Rotate in the up or down direction dragged by touch & drag. In this embodiment, the touch and drag is rotated in a row direction such as 'pickerview' or 'spindle' used in an iPhone or an Android phone, for example, a number or letter belonging to a set that is rotated. It is moving to appear.

Further preferably, according to another embodiment of the present invention, in the embodiment of the secret code input device in the mobile terminal according to Figs. 1 to 4, the block module 120 is the control module of Fig. 1 according to the setting input 130, preferably, the code set generation module 131 of Figs. 2 to 4 moves the position order of the blocks in which each set is arranged. Accordingly, in addition to rotating within each set, each set itself circulating on the block moves its own seat and the desired set is arranged in a desired order, so that a user can easily input a secret code of each digit according to the user's taste. Will be. For example, even if a set corresponding to each digit of the secret code in the application, for example, a number set, an alphabet set, a special symbol set, a Korean character set, or the like is set, the user can move the digit of the block when the password is input. By placing the desired set in place of the desired place, the user can generate and enter the desired secret code.

Preferably, in one embodiment, the control module 130 according to Fig. 1, preferably the code set generation module 131 according to Figs. 2 to 4 is set in advance in each block according to the settings in the application Place the set of modules 110. Accordingly, the type of the set circulated in each block for inputting the secret code can be set initially, so that the secret code of the desired type can be properly input even on the server (not shown). For example, in order to generate a strong security password on the server side, not only a number but also a set of characters, preferably an alphabetic character, may be initially placed within the initial digit range. Of course, in the present embodiment, the configuration of the embodiment that enables the configuration of the preceding code set change module 135 and / or the position shift of the block may be further included and applied.
