Description

Method for Input Of Information Using Virtual-Mouse-Method}

The present invention relates to an information input method and a computer readable recording medium having recorded thereon a program for realizing the method.

The current method of entering secret information from a remote location to a service provider's computer is mostly for entering a password. In the prior art, a method of inputting secret information includes a method of inputting fixed secret information and a method of irregularly inputting secret information.

First, a method of inputting fixed secret information is described as follows.

The service user makes a remote connection to the service provider in order to use the service. When the service user accesses, the service provider requests the secret information from the user to proceed with the service. At this time, an input window for requesting input of secret information appears on the user screen. The service user enters his secret information using the keyboard and transmits it. At this time, the secret information appearing in the secret information input window is represented by unknown characters such as '*' or '#' or not displayed at all so that others cannot see it from the side.

However, the above method has the following problems.

First, even if it is displayed as a character ('*', '#', etc.) that cannot be seen by other people, if you remember the location of the keyboard input by the service user, you can find out the secret information. There is a problem.

Second, if a hacker inputs a combination of secret information indefinitely, there is a problem that the secret information can be found. In particular, the user can more easily find out when the secret information is composed of information related to his or her birth date, telephone number, social security number, and the like.

Third, there is a problem that the information can be found by hacking the user's computer even if the next person enters the secret information so that they cannot see it. Hacking method of the user computer is a method of hacking by saving the input content of the keyboard used by the user. In particular, the hacking program currently being used can easily leak the input contents of the keyboard input by the user.

Fourth, defense against hackers' reverse engineering attacks. In reverse engineering attacks, Trojan horses or viruses that allow third parties to monitor computers and running programs can be read into the user's computer to read the progress and information of service programs. It is an act of giving.

That is, the conventional method of inputting the fixed secret information as described above can enter information such as password, social security number, account number, credit card number, security message, etc., but as described above There is a problem that the security is weak because it can be easily leaked.

Next, a method for making secret information irregularly inputted is as follows.

This method is not fixed secret information, but irregularly changing the secret information every time. In this method, the random number is passed to the user, the random number is combined with the information using a certain function, converted, and then input. The random number index value of the random number table previously promised between the service provider and the user is passed to the random number index value. There is a random index input method for inputting a corresponding random number value. By doing so, the value of entering secret information every time is changed irregularly so that even if the input secret information is leaked, it is of no use.

However, the above method has the following problems.

First, random number and secret information is calculated using a function, and then the random number input method that inputs the result value shows the random value in the process delivered to the user, and the function used is also repeated hacking or other paths. There is a problem that can be known through. The remaining secret information can then be known through mathematical calculations.

Secondly, the random number input method, which indicates that the value passed from the user's computer is not a random value but an index value to find the random number in the random number table, is a method of preventing the random number from being found, but it is a fixed secret when the random number is lost or stolen. There is a problem that the secret information is leaked more easily than the information input method. In other words, the problem with this method is that the random number corresponding to the information is external and anyone who acquires it can easily use the service. Therefore, if a user of a service is lost or stolen, the service provider should be reported as soon as possible to minimize the damage.

Third, the above method can be more secure than the method of inputting fixed secret information, but can not enter information such as social security number, account number, credit card number, secret message that requires security, etc. There is a problem that follows.

Examples of problems in leaking secret information in a service using the conventional technology as described above are as follows.

First, the leakage of personal secret information through the Trojan horse is as follows. Recently, Trojan-based programs have become a social problem because they infiltrate personal computers and leak personal information. In other words, 'Dropper / HotKeysHook' is a Trojan-based hacking program spreading through the Internet, which is expected to cause damage caused by the leakage of confidential information stored on the computer. There is, however, a virus always preceded and the vaccine against it is produced and distributed afterwards, so it is not considered to prevent damage completely.

Next, a problem that occurs when a password is leaked in a communication service will be described. PC communication such as Cheon Lian, Hitel, etc. authenticates users by entering ID and password. Most PC communication service programs require users to enter their passwords on the keyboard, and the input contents are displayed as '*' characters on the screen so that they cannot be seen. If a hacker installs a hacking program on the user's computer, the user's input is saved. In this way, if the user's password is leaked, the corresponding communication service may be used in a direction not intended by the user. In particular, it can be used as a means of posting a slanderous article, using a paid service, etc. by a hacker, or hacking the service or elsewhere. In this case, the user may be charged with a charge that he did not use or suspected of hacking elsewhere. It is also blacklisted from service operators and penalized. It is difficult for service operators to identify unidentified illegal users when hacked.

Next, a description will be given of the damage caused when the password leakage of the Internet game. Games using the Internet are increasing. In particular, the number of users who enjoy a game by joining a service provider that provides a game is increasing. There is a phenomenon that virtual goods acquired in the game are traded by cashing in real life. Therefore, the number of Internet crimes that hack game IDs and sell goods on the Internet with the corresponding IDs is increasing. In addition, in game competitions, a lot of cases of hacking a specific ID to manipulate the odds or damage. Users who have been hacked into game IDs frequently lose the game value they have acquired. Such damage is seen as a case of damage in Internet games such as Lineage and Starcraft's Battle.net.

Next, the damage caused by the leakage of personal information from the Internet service is described as follows. Currently, there are virtual currencies such as cyber money, mileage points and points on the Internet. In these service companies, when a certain amount of virtual currency is collected, there are many events that give a product or a corresponding gift. In these services, illegal users steal IDs and steal other members' cyber money, mileage, points, and other cryptocurrencies.

Next, the problem that occurs when the account number and password leakage in the banking transaction is described as follows. Most commercial banks in Korea are adopting Internet banking. Internet banking is the ability to view banking services over the Internet. When banking on the Internet, the bank delivers the certificate to the user and performs the initialization process. After the process of receiving the certificate, the user uses the account number, various passwords, and issued random number index. However, a certificate is nothing more than a certificate for the computer you use. Therefore, copying the certificate of the computer or using the computer allows access to the bank. In addition, the account number or various passwords entered by the user can be easily obtained by the hacker using the current hacking program. In addition, the random number index table has a limited random number index value, which can be leaked when a hacker repeatedly tracks. Once a hacker obtains personal banking information, it can cause financial damage to the user. In recent years, the environment in which the computer used by the user uses the computer jointly in a company, a school, a PC room, etc. is increasing, and the user using these computers is likely to be harmed.

Next, a description will be given of the problems arising from the securities password leakage in securities transactions. Recently, Internet stock trading (cyber trading) is increasing rapidly. Secret information used in securities trading includes an ID and password for accessing a securities service provider, an account number and a transaction password for the transaction. These secrets can be easily extracted by hackers storing the keyboard contents of the user's computer. If a hacker leaks a user's secret information and makes an arbitrary transaction or transfers stocks between accounts, he may suffer financial damage.

Next, a description will be given of the problems caused by the leakage of credit card information in e-commerce as follows. In recent years, as the number of Internet users has increased rapidly, commerce using the Internet has been increasing rapidly. There are many ways to do business using the Internet. The most commonly used method is to buy a product by entering the credit card number and its password after accessing the trading company. If a service user purchases goods on the Internet through a computer and his information is leaked by a hacker, the leaked credit card information is purchased through the Internet regardless of his intention and suffers financial damage. Even if a credit card number is used, it is easier to illegally use credit card information. In order to strengthen security in services such as Internet banking, Internet transaction, and e-commerce, encryption method such as SSL is adopted. However, these methods encrypt and transmit secret information such as account number and password immediately before transmission. . Therefore, if hacking is performed in the input step, it is difficult to prevent the leakage of secret information. In particular, the recent accident of leaked credit card information in France can make an illegal credit card using only the credit card number, so the leakage of the credit card number may develop into a very serious problem in the future.

As described above, if the secret information is illegally leaked and illegal use of the secret information is made, the user may suffer material and mental damage.

The present invention is to solve the above problems, when the service user enters the secret information, such as his password, social security number or secret message that requires security at a remote location, for illegal leakage of (hacking), etc. Among the secret information input methods on the Internet for providing safety, an information input method using a virtual mouse method and a computer-readable recording medium recording a program for realizing the method are provided. have.

3 is a flow chart of another embodiment of an information input method using a virtual mouse method according to the present invention;

4a to 4f are detailed views illustrating a process of inputting information among information input methods using the virtual mouse method according to the present invention.

5 is an exemplary view of an input window for inputting information using a virtual mouse method according to the present invention.

According to an aspect of the present invention, there is provided an information input method using a virtual mouse method applied to an information processing system, comprising: a first step of outputting a key character index value to a user terminal; The mouse pointer corresponding to the key character indicated by the key character index value is moved by the user, and the character value on the selected screen keyboard and all mouse pointers except the mouse pointer are moved to store the character value on the selected screen keyboard in the terminal. A second step of doing; A third step of repeating the first and second steps by the number of secret letters and receiving the information stored in the terminal to identify key letters for the key letter index values transmitted in the first step for each secret letter; step; A fourth step of extracting one secret character input from the mouse pointer corresponding to the key character using the key character identified for each secret character through the third step and the values stored in the second step; And a fifth step of extracting final secret information by repeating the fourth step by the number of secret characters.

The present invention also provides an information input method using a virtual mouse method applied to an information processing system, comprising: a first step of outputting a key character index value to a user terminal; A second step of storing the changed relative coordinate value of the mouse pointer in the terminal when the mouse pointer corresponding to the key letter index value is moved and selected by the user; After repeating the first and second steps as many as the number of secret characters, receiving the information stored in the terminal, the changed relative coordinate value stored in the second step for each secret character and the key characters transmitted in the first step Determining a starting coordinate value of a key letter with respect to the index value; A fourth step of extracting one secret character input from a mouse pointer corresponding to the key character using the changed relative coordinate value and the start coordinate value of the key character identified for each secret character through the third step; And a fifth step of extracting final secret information by repeating the fourth step by the number of secret characters.

Illegal outflow (hacking, etc.) as used in the present invention is various as follows.

First, a third person can see the information entered by the human eye. This method is to look at the characters on the screen, or to see and detect the position of the hand of the keyboard that is input when it is seen in the form of unknown characters on the screen.

Second, the third party infiltrates illegal software into the user's computer and reads the input contents of the keyboard or mouse input by the user.

Third, the third party infiltrates the user's computer with a Trojan horse or virus that can monitor the computer and the executed program using reverse engineering, and reads the progress and information of the service program.

Fourth, when an input of confidential information is transmitted through the Internet, a third party illegally copies and transmits the contents.

Fifth, in the case of a password which is one of user secret information, a third party repeatedly enters a random number to obtain user authentication.

In the present invention, a virtual mouse method is a method of creating two or more mouse pointers on a screen keyboard, designating a mouse pointer to be used for input using key characters, and inputting information using the mouse pointer. There are two methods for specifying a mouse pointer to be used for input using key characters: a mouse pointer having the same shape as a key character, and a mouse pointer positioned at a key on the screen keyboard having the same shape as the key character. The method of storing the input information includes a method of storing all text values input from each mouse pointer and a method of storing the relative coordinates of the mouse pointer.

The screen keyboard according to the present invention refers to the implementation of the number of letters, numbers, symbols, figures, etc. necessary on the screen for proper input of secret information.

In the present invention, a key character refers to a character used to designate a mouse pointer, which is defined between an inputter and an interpreter.

The key character index method used in the present invention refers to a method of using an index value to designate a key character to be used for input among the random characters shared between a service user and a provider.

The secret information referred to in the present invention refers to various passwords, social security numbers, credit card numbers, account numbers, authentication numbers, etc., and includes letters (Korean, English, Japanese, etc.), numbers, symbols, and combinations thereof.

The secret character referred to in the present invention refers to each letter, number, symbol, etc. constituting secret information.

The important reason for the illegal leakage of secret information is that the information input by the user exists in the input / output device and memory of the user's computer. The input value of the user is passed through the memory and the output device through the input device. If a hacker hacks into a user's computer, the secret information could be leaked at any stage. To prevent this, the user's computer should not know the actual value when the information is entered or transferred. The way that the user computer does not know the secret information is to have the service user enter the secret information using the virtual mouse method and the key character index method. That is, the secret information input to the user's computer is input to other values changed using the virtual mouse method and the key character index method.

On the screen of the user's computer, several mouse pointers are present on each key and move in the same direction each time the user moves. Using the key character index method, the contents delivered by the service provider to the user are composed of key index values, so that the key character used is unknown. If the key character used for input is unknown, the illegal mouse cannot know the actual mouse pointer in the virtual mouse method, and thus illegal users cannot enter meaningful information and cannot know which of the legitimate user input values is meaningful. .

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 1 to 5.

1 is a configuration diagram of an embodiment of an information processing system to which the present invention is applied.

As shown in the figure, the information processing system to which the present invention is applied is largely composed of a service user system 110 and a service operator system 130 and a network 120 connecting the two systems. The network 120 here includes both a wireless network and a wired network.

The service user system 110 processes information transmitted from a network through an input unit 111 for inputting information, an interface 114 for connecting to a network, and an interface 114 or inputs data from the input unit 111. And an information processing unit 113 for processing the data, an output unit 112 for outputting the processed result, and a storage unit 115 for storing various kinds of information. In this case, the information processing unit 113 includes a secret information requester 116 for requesting input of secret information to the user, and a secret information interpreter 117 for interpreting secret information input from the user.

The service operator system 130 may include an input unit 131 for inputting information, an interface 135 for connecting to a network, and an information processing unit for extracting information from user information transmitted from the network through the interface 135 ( 134), a data management unit 133 for storing information about the user and information on the key character index value, and an output unit 132 for outputting the processed result.

At this time, the output unit 112 of the service user system 110 serves to show a user the key character index value received from the service operator system 130, and the input unit 111 serves to receive secret information from the user. . The input unit 111 allows the user to input the secret information by using a virtual mouse method. Since the secret information is input using the virtual mouse method, the problem of the method of storing the input contents, which is a problem of the existing input device, is solved. Using the virtual mouse method, which causes multiple mouse pointers to appear on the screen when using the on-screen keyboard, the user's computer does not know which is the actual mouse pointer and therefore cannot know its input. In order to find one's own mouse pointer among several mouse pointers, only the user can find it using the key character color method. The service operator transmits a key character index value corresponding to the key character to be started to the service user, and the service user can find and enter a mouse pointer corresponding to the key character using the key character index method.

In addition, the secret information processing unit 134 of the service operator system 130, the secret information requester 136 for requesting the secret information to the user when attempting to access the user and the secret information interpreter 137 for interpreting the information transmitted from the user It consists of.

The secret information requester 136 manages a key character index value delivered to the user, and performs a key character index value and a secret request to the user. That is, the secret information requester 136 requests the secret information of the user when the user attempts to access the service operator system 130, and the secret information requester 136 requests the secret information from the service user system 110. Pass the number of key character indexes. The key character index value passed to the user is a value shared in advance between the operator and the user.

The secret information interpreter 137 is composed of a module for interpreting secret information from information received from a user. The information transmitted from the service user is interpreted using the key character index value that was delivered when the secret information was requested.

That is, the secret information processing unit 113 performs a task on the secret information request transmitted from the operator or interprets the secret information input from the user.

2 is a flowchart illustrating an embodiment of a secret information input method using a virtual mouse method according to the present invention, and FIG. 5 is an exemplary view of an input window for inputting secret information using a virtual mouse method according to the present invention.

The process in which the user accesses the service operator system 130 from a remote location and processes the input information is as follows.

The service user system 110 connects to the service operator system 130 at a remote location using a wireless network or a wired network (202).

The secret information requester 136 of the service operator system 130 requests an ID input from the service user system 110 (204).

The user inputs an ID through the input unit 111 of the service user system (206).

Steps 202-206 can be omitted after service user authentication.

The secret information requester 136 of the service operator system 130 requests the service user system 110 to input information. At this time, the secret information request and key character index values are passed (208). The transmitted key character index values are stored in the storage unit 115. The output unit 112 of the service user system executes an input window for inputting secret information (an input window in the form of FIG. 4A or 5). The input window consists of a commentary instructing you to enter the secret information, an information box indicating the status of the secret information, a key character index box, and an on-screen keyboard. A mouse pointer appears for each key position on the screen keyboard.

The service user confirms the key character by looking at the key character index value shown in the key character index box (210).

The service user selects the mouse pointer using the key character identified in step 210 (212). At this time, there are two ways to select the mouse pointer. The first method is to select a mouse pointer having the same shape as the key character identified in the process 210 (that is, the key character corresponding to the start index value 1054 in the case of the input window as shown in FIG. '1' is a method of selecting a mouse pointer having a shape of '1'), and the second method is a pointer located on a key of a screen keyboard corresponding to a key character identified in step 210 as a mouse pointer. If the key character corresponding to the start index value 1054 is '1' in FIG. 4F in the case of the input window as shown in FIG. 5, the method of selecting the mouse pointer above '1' on the screen keyboard is selected. have.

The selected character is moved on the screen keyboard by moving the selected mouse pointer (214). At this time, the input device used in the virtual mouse method includes a mouse, a keyboard, a touch screen, etc. The method of selecting a character to be input on the screen keyboard by moving the selected mouse pointer is as follows. First, in the input method using a mouse, the entire mouse pointer is moved like a normal mouse to a desired position, and a mouse button is clicked to input. Second, in the input method using a keyboard, a mouse pointer is moved to a desired position by using an arrow key on the keyboard and the input key is selected. Third, an input method using a touch screen is a method of moving a mouse pointer with a finger or a pen on a touch screen, placing the mouse pointer at a desired position, and selecting and inputting a desired button with a finger or a pen. Fourth, as a method combining the three methods, it refers to a method of moving the mouse pointer to a desired position by using each of the above methods and then inputting the respective methods.

When a character is input, the processing unit 113 of the service user system 110 stores all the character values indicated by the respective mouse pointers in the storage unit 113 to store one of the secret characters of the secret information composed of a plurality of secret characters. The input process ends (216).

The process (210 to 216) is repeated by the number of secret characters of the secret information to be input by the service user (218).

The information processing unit 113 transmits the text values (the text values generated through the process of 218) for each secret text constituting the secret information stored in the storage 115 to the service operator system 130 (220).

The service operator system 130 grasps a key character corresponding to a key character index value for each secret character of the secret information transmitted when the secret information is input (222).

The secret information interpreter 136 of the service operator system 130 stores the text values stored in association with the first secret text among the received text values (the text values received through the process 220). By extracting the character corresponding to the identified key character, one secret character is extracted from the secret information consisting of a plurality of secret characters (224).

The processes 220 to 224 are repeated by the number of secret characters of secret information input by the service user (226).

Finally, the secret information input by the user is identified through the above process (228).

3 is a flowchart illustrating another secret information input method using the virtual mouse method according to the present invention.

The process in which the user accesses the service operator system 130 from a remote location and processes the input information is as follows.

Processes 302 to 314 for inputting one secret character constituting secret information by accessing the service operator system 130 by the service user are the same as the processes 202 to 214 described with reference to FIG. 2.

When one secret character of the secret information of the user is input through the above process, the information processing unit 113 of the service user system 110 stores the changed relative coordinates of the mouse pointer in the storage unit 115 (316). This part is different from the process in FIG.

The process (310 to 316) is repeated by the number of secret characters of the secret information input by the service user (318).

The information processing unit 113 transmits the relative coordinates (relative coordinates generated through the process 318) for each secret character constituting the secret information stored in the storage 115 to the service operator system (320).

The service operator system 130 grasps the key character corresponding to the key character index value for each secret character of the secret information transmitted when the secret information is input (322).

By extracting the characters input by the service user by adding the starting coordinates of the key characters identified in the process 320 and 322 and the delivered relative coordinates, one secret character is extracted from the secret information consisting of a plurality of secret characters (324). .

The process 320 to 324 is repeated by the number of secret characters of the secret information input by the service user (326).

Finally, the secret information input by the user is identified through the above process (328).

The method 216 of storing and transmitting the text values indicated by the mouse pointers as in the process of FIG. 2 has an advantage that the process of the service operator system 130 is fast, but the load is placed on the network 120. It has the disadvantage of being.

On the contrary, the method of storing the changed relative coordinates of the mouse pointer as in the process of FIG. 3 may have an advantage that the service user system 110 or the network 120 does not have a load, but the service operator system 130. There is a disadvantage in that the throughput is increased due to the increase in throughput.

Therefore, an appropriate method is used depending on the configuration of the system to be applied of the two methods.

In addition, the information input method using the virtual mouse method described with reference to FIGS. 2 and 3 may not be executed online only as described with reference to FIG. 1.

That is, the service operator system 130 of FIG. 1 may be viewed as a single user system. In this case, in a offline state not connected to a network, a user may use his or her own terminal (that is, the service operator illustrated in FIG. 1). System 130 may be a terminal of a user) to input information using a virtual mouse method.

For example, if a user using the personal computer 130 wants to use the virtual mouse method described above as a secret information input method in his computer, there is no transfer of information through the network 130. When secret information is input through the input unit 131 in the same process as in FIGS. 2 and 3 according to the secret information request from the secret information requester 136, necessary materials are stored in the data management unit 133 and the information interpreter 137 interprets the information input by the user using the information stored in the data management unit 133.

A concrete use example is as follows.

First, a user wants to lock his computer.

Secondly, when a user enters a password for files used by the user.

In addition, in various cases where confidential information should be input offline, the same method may be used as in FIGS. 2 and 3. That is, the information input method using the virtual mouse method described with reference to FIGS. 2 and 3 may be used in various ways in a terminal offline.

4A to 4F are detailed views illustrating a process of inputting information in the secret information input method using the virtual mouse method according to the present invention, and the information input process 210 to 218 and 310 to FIG. 2 or 3. 318) is described as an example of inputting the information 'TEST'. 4F illustrates key character index tables used in the processes of FIGS. 4A to 4E.

When the service user connects to the service operator system 130 (202) and enters an ID (202,204), the start index value is passed to 1054 as shown in FIG. 4A, and the key corresponding to 1054 is '1'. Search through the character index table (FIG. 4F). The mouse pointer of the same shape is found among the mice displayed on the screen keyboard in the shape of the key letter '1' (in FIG. 4A, the mouse shaped like the key letter 1 is positioned on the keyboard 't'). Then, move the mouse pointer to 'T', which is the secret letter you want to enter, and click.

After entering 'T' with the mouse pointer (the mouse pointer in the shape of the key character '1' in Fig. 4b is located above the 'T'), the index value is set as shown in Fig. 4b for the second secret character. Passed to 1055, the key character index table finds that the key character corresponding to 1055 is 'n'. The mouse pointer in the shape of the key letter 'n' is found among the mouse pointers displayed on the screen keyboard (in FIG. 4B, the mouse pointer in the shape of the key letter 'n' is located on the keyboard '='). Then, move the mouse pointer to 'E', which is the secret letter, and click.

After entering 'E' with the mouse pointer (the mouse pointer in the shape of the key character 'n' in Fig. 4c is located above the 'E' character), the index value is shown for the third secret as shown in Fig. 4c. This is passed to 1056, and the key character index table finds that the key character corresponding to 1056 is 'F'. The mouse pointer in the shape of the key letter 'F' is found among the mouse pointers displayed on the screen keyboard (the mouse pointer in the shape of the key letter 'F' is located above the '!' Character in FIG. 4C). Then move the mouse pointer to 'S' which is the information you want to input and click.

After entering 'S' with the mouse pointer (the mouse pointer in the shape of the key letter 'F' in Fig. 4d is located above the 'S' character), the index value is set as shown in Fig. 4d for the fourth secret character. Passed through 1057, the key character corresponding to 1057 is 'P'. The mouse pointer in the shape of the key letter P is found among the mouse pointers displayed on the screen keyboard (the mouse pointer in the shape of the key letter 'P' is located above the 'I' in FIG. 4D). Then move the mouse pointer to 'T' which is the information you want to input and click.

Inputting 'T' with the mouse pointer (the mouse pointer in the shape of the key letter 'P' in FIG. 4E is located on the 'T') completes the input of secret information by entering all four digits of the secret character.

Brief description of the application examples of the present invention as described above are as follows.

First, it is used for the transfer of state secret information.

Second, it provides security for banking and securities transactions.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

In the present invention as described above, even when the secret information input by the user is stored in the user's computer by inputting the secret information using the virtual mouse method and the key character index method, the information cannot be easily obtained even if the third party observes the input process. It is difficult to know the secret information that is difficult to leak information has an excellent effect.

In addition, when a random number index method or a one-time password type password generator and receiver used by a bank are lost / stolen directly, the password may be leaked directly, and the key character index information according to the present invention may be lost. / If stolen, it is not a direct leak of confidential information, so it has an excellent effect of not being able to authenticate a user by itself.

In addition, the present invention has an excellent effect that it is possible to avoid being hacked to intercept the character value generated in the keyboard during password input, which is a problem of the method using the existing keyboard.

In addition, the present invention has an excellent effect that can be provided even if the hacking during transmission because the secret information is modified and stored and transmitted using the virtual mouse method.

In addition, the present invention has an excellent effect that can be effectively used for the transfer of information requiring security, such as credit card numbers, account numbers, social security numbers, secret messages, as well as passwords, while the existing methods are limited to passwords. .

In addition, since the present invention uses a key character index method, hacking can be prevented through repeated tracking of a hacker, and even if a service user loses key character index information, user authentication can be performed using the method according to the present invention. There is an excellent effect that the illegal entry of secret information is impossible because illegal access of the acquirer who does not know the password is not allowed.

Briefly summarized the effects of the present invention as described above are as follows.

First, the service user computer does not know the actual value of the secret information entered.

Second, even if the values entered by hacking the service user computer are leaked, they cannot be interpreted.

Third, the key character used by the service user as the reference coordinate of the input is irregularly changed at every attempt, so that a regular pattern does not occur, so it is difficult to trace even if the user inputs a fixed value such as a password or credit card number repeatedly.

Fourth, even if the service user loses the key character index information, if the user authenticates by the method according to the present invention, illegal access of the acquirer who does not know the password is not allowed, and thus illegal input of the information is impossible.
