Abstract

PROBLEM TO BE SOLVED: To provide a method for inputting a personal identification number or a password, even when being peeped, unlikely to be viewed and capable of protecting key input information from cracking without using a character input key.SOLUTION: When a login ID is input from an input screen and an input column of a personal identification number or a password is selected, a plurality of character strings are displayed on an input screen. When a member operates to move a cursor in a displayed character string and presses a clear key or the like to erase a specific character in the character string, the erased character is stored for each character string. When the erasing operations is finished in all the character strings and the member presses a confirmation key, the plurality of stored characters are arranged in order of the positions of the character strings or in the erased order, and are sent to a server for providing services, with being defined as the personal identification number or the password.

Description

  The present invention relates to restriction of access to a node of a computer system or computer network, and more particularly to a method for inputting a member's personal identification number or password and a program thereof.

  Conventionally, when a personal identification number or password (hereinafter referred to as a personal identification number) is entered, the entered character itself is not displayed, and is generally replaced with another character such as “*”. It is. However, since such an input method cannot confirm the characters input by the user, there is a problem that erroneous input is likely to occur. In particular, in the case of a password that uses characters other than numbers, a small terminal such as a cellular phone has a risk of erroneous input because a plurality of characters other than numbers are assigned to one key.

  For this reason, for example, in Japanese Patent Application Laid-Open No. H10-318707, a character being entered in a password is displayed on the screen until the input is confirmed, and when the input is confirmed by a predetermined operation, the character is deleted with “*”. Such a password input method is described.

  Further, in Patent Document 2, while the password is being entered, it is replaced with a specific character “*”, and when the user presses the “Confirm” button after the input is completed, a confirmation number having the same number of characters as the input password is displayed. When a specific number in the confirmation number (a number that exists in the same position as the confirmation target character in the input PIN) is input, the verification target character is recognized based on the input digit, and the verification target character is A character string input support device or the like that generates and displays a dummy character string that is present at the same position as the remaining characters by random numbers is described.

JP 2001-166843 A JP 2007-188515 A

  The method for inputting a password or the like described in the above-mentioned patent document is provided with means for displaying the original character when necessary by replacing the input character such as the password with another character on the screen. However, in the method of Patent Document 1, a password number is displayed until it is confirmed even in a short time, so if you carefully look at the input screen and key operations, the password number will be known. Danger remains. In the method disclosed in Patent Document 2, it is assumed that a password is input using a character input key. When inputting with a PC (Personal Computer) or the like, information input from a keyboard is stolen. It cannot be prevented that key input is cracked by key logger type spyware and the password is stolen. On the other hand, in recent years, a software keyboard for inputting without using a keyboard is used to prevent cracking. However, there is a problem in a mobile phone having a small screen.

  Therefore, in the present invention, in view of the above-described problems, in any use environment such as a mobile phone or a PC, even if the user looks into the screen, the personal identification number is difficult to be seen, and the character input key is not used. Another object of the present invention is to provide a method for inputting a personal identification number or the like that can protect against cracking of key input information.

  In order to solve the above problems, the password or password input method of the present invention provides the following solution.

  A method for inputting a personal identification number or password for a member to receive a service via a network, wherein the member inputs a login ID from an input screen and selects the input field for the personal identification number or the password. A step of displaying a plurality of character strings on the input screen; and a step of erasing a specific character in the character string from the character string in response to a cursor movement operation and a predetermined key press in the character string. Storing the erased characters for each of the character strings; causing the member to confirm completion of the erasing operation; and receiving the confirmation, the plurality of stored characters And transmitting it to a server providing the service as a password or a password.

  According to such a configuration, when a member inputs a login ID from the login input screen and selects an input field such as a personal identification number, a plurality of character strings are displayed on the input screen, and the member is displayed in the character string displayed. When the cursor is moved and a predetermined key (clear key or the like) is pressed to erase a specific character from the character string, the erased character is stored for each character string. When the erasing operation is completed for all character strings and the member presses the confirmation key, the stored characters are recognized as a password or password and transmitted to a server that provides the service.

  In this way, since the personal identification number or the like can be input only by operating the cursor movement key and the clear key without using the character input key, there is no fear that the key input information is stolen by a malicious program. In addition, since the characters such as “input” passwords are immediately erased from the screen, it is possible to reduce the danger of others looking into the input screen and reading the characters.

  In the above input method, more preferably, each character of the character string is arranged according to a random number or a predetermined rule. By doing so, the position of each character in the displayed character string is not fixed, and it becomes difficult to infer the character erased from the movement of the cursor.

  In the present invention, a plurality of erased characters are stored and a password is generated by combining these characters. There are two methods for the combination. In the first method, the erased characters are stored in an order corresponding to the display position on the character string input screen. In this way, the position of the character string corresponds to the digit such as the password, so for example, to input a 4-digit password, a 4-line string is displayed, and each line corresponds to each digit of the password. By doing so, the risk of erroneous input can be reduced.

  In the second method, erased characters are stored in the erased order. In this way, since the order of the erased characters corresponds to the digits such as the password, the risk of guessing the entered (erased) characters from the position of the character string on the screen can be reduced.

  The character to be erased may be designated at a position in the character string in accordance with the operation of a slide switch provided in the input device. In other words, a slide switch provided in the operation input unit is used to move the cursor to a character to be erased. By doing so, the cursor movement operation and the pressing operation of the clear key or the like can be performed simultaneously with both hands or another finger, so that the operability is improved.

  More preferably, the character string includes all alphanumeric characters and a predetermined symbol defined as usable as a password, and if the character to be erased does not fit on the input screen, the character string is displayed on the screen. Scroll horizontally or change the display frame of the character string sequentially.

  The characters used for the password are normally alphanumeric characters and symbols, but it is difficult to display them all in one line of character string because of the screen size in a small portable terminal. Therefore, characters that do not fit in the screen can be displayed by scrolling horizontally using the cursor movement key or the slide switch. Alternatively, the display frames for alphanumeric characters and symbols may be switched each time input of one character is confirmed. For example, when entering a 4-digit password, the display frame should be one line, the first display should be in the thousands, the next display in the hundreds, the next display in the tens, and the last display in the first place. , And display assignment destinations may be sequentially displayed. In this way, it is possible to handle even if all the input frames cannot be displayed on one screen.

  Further, the character string may be displayed by being divided into character blocks of numbers, letters and symbols. That is, each character string may be displayed separately in blocks of numbers, alphabets, and symbols instead of one line. In this way, the trouble of scrolling the screen can be eliminated.

  In addition, when displaying divided into the above character blocks, it is difficult to display a plurality of the same characters in each character block in advance, so that the erased characters are displayed again at the end of the character block. It is preferable to do. For example, if “a” is deleted in the character string “abc... Z”, “bc. This is because the same character may be used multiple times in the password.

  Each of the above input methods is to input a personal identification number etc. by erasing the specified character in the character string, but instead of “erasing”, the selected character is You can do the same thing by “inserting” into the string.

  In order for a member to receive a service via the network, a password or password input method, wherein the member inputs a login ID from the input screen and selects the password or password input field, Displaying a plurality of character strings on the input screen; and inserting a specific character in the character string in the character string in response to a cursor movement operation and a predetermined key press in the character string; Storing the inserted characters for each of the character strings; causing the member to confirm completion of the inserting operation; and accepting the confirmation in response to receiving the confirmation. And transmitting to the server that provides the service as a number or a password.

  In such a configuration, for example, when “a” and “c” are inserted in the character string “abc... Z”, “aabcc. In this case, “input” characters remain on the screen, but on the actual screen, only a large number of characters are arranged in a plurality of character strings.

  The method for inputting a personal identification number or the like according to the present invention can also be understood as an invention of a program that causes a computer to execute each processing step as follows. Such a program may be separately provided by downloading or the like in addition to being incorporated in advance in hardware.

  A computer program for allowing a member to enter a password or password so that the member can receive a service via the network. The member inputs a login ID from the input screen and selects the password or password input field. In response, a step of displaying a plurality of character strings on the input screen, a specific character in the character string in the character string in response to a cursor movement operation and a predetermined key press in the character string. Erasing or inserting the information in the table; storing the erased or inserted characters for each character string; causing the member to confirm completion of the erasing or inserting operation; and receiving the confirmation. In response, the stored plurality of characters as a password or password is transmitted to a server that provides the service. Preparative, and characterized by causing a computer to execute.

  According to the present invention, in any use environment such as a mobile phone or a PC, a personal identification number or the like is not visually recognized even if the user looks into the screen, and is protected against cracking of key input information without using a character input key. It is possible to provide a method for inputting a possible password.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

  FIG. 1 is a block diagram showing an outline of a computer system according to an embodiment of the present invention. The computer system includes an authentication server 100 connected to a network 300. The network 300 can be any computer network. However, in the following description, it is assumed that the computer network is the Internet as a typical example.

The authentication server 100 includes a CPU (Central
A general computer including a processing unit (ROM), a read only memory (ROM), a random access memory (RAM), and a hard disk drive (HDD), and includes a communication unit 101 that performs communication control via the network 300. I have. The authentication server 100 performs an authentication function for accessing a Web server (not shown) that operates the Web site, but may be configured as a Web server and a single server. The authentication server 100 includes a member information storage unit 102 that stores member information such as a Web site that provides a service to a user, and performs login authentication when accessing a service provided by the member.

  In addition, a large number of terminal devices 200 possessed by the user are connected to the network 300. The terminal device 200 is typically a PC, a PDA (Personal Digital Assistant), or the like, and includes a CPU, a ROM, and a RAM as hardware, and functionally, a communication unit 201 that performs communication control, an HDD, and an optical disk. , A storage unit 202 composed of a non-volatile memory (SD card, USB, etc.), an operation input unit 203 such as a keyboard and a mouse, and a display unit 204 such as an LCD (Liquid Crystal Display) or CRT (Cathode Ray Tube). ing.

  In addition, a large number of mobile terminals 210 and a large number of base stations 400 possessed by the user are connected to the network 300. The mobile terminal 210 is typically a mobile phone, a PHS (Personal Handy-phone System), a smartphone, a tablet terminal or the like, and similarly includes a CPU, a ROM, and a RAM as hardware, and is functionally wireless. A communication unit 211 that controls communication, a storage unit 212 that includes a non-volatile memory (such as an SD card), an operation input unit 213 that includes operation keys (operation buttons) and an electronic pen, and a display unit 214 that includes an LCD. It has. The mobile terminal 210 performs wireless communication with the nearest base station 400 and can communicate with an arbitrary computer such as the authentication server 100 connected to the network 300. Although the portable terminal 210 and the terminal device 200 are functionally equivalent, since the portable terminal 210 is required to be downsized, the operation input unit 213 and the display unit 214 are physically limited.

  The website here provides services only to users (members) who have signed a use contract in advance (for example, bank net banking services), and each member has a contractor number or user ID. A login ID such as a personal identification number and / or a password is assigned in advance. The login ID, password, and the like are stored as a database in the member information storage unit 102 of the authentication server 100. A member who intends to use a service provided on the Web site first logs in to the authentication server 100 using his / her own terminal device 200 or mobile terminal 210 connected to the network 300. In response to an access request from the terminal device 200 or the portable terminal 210, the authentication server 100 displays a login screen (Web page) on the terminal and requests input of a login ID, a password, and the like.

  FIG. 2 is a diagram showing an example of a password input screen according to the first embodiment (embodiment 1) of the present invention. In this embodiment and the following embodiments, a case where a user logs in using a mobile phone will be described. However, the same is basically applied to a PC or the like except that the screen size is different.

  First, a display portion and an input portion of a mobile phone will be briefly described with reference to FIG. As shown in the figure, the mobile phone includes a liquid crystal screen as the display unit 214 and an operation input unit 213 including various operation buttons (operation keys). The operation input unit 213 typically has a cross key 10 for moving the cursor, a center key 11 for confirming input (sometimes referred to as a navigation key together), and a function for making / receiving a call. A call start key 12, a clear key 13 (sometimes referred to as “erase key” or “return key”) for erasing input characters, and a call end key 14 for ending a call are provided. The call start key 12 may also have a function of switching between uppercase and lowercase characters. Further, the call end key 14 often has both a power on / off function and a function for returning to the standby screen.

  15, 16, 17 and 18 shown in the figure are function keys. For example, the key 15 is a menu display function, the key 16 is a mail function or character input mode selection function, the key 17 is a camera function, and the key 18 is a telephone. Assigned to a book function, a Web connection function (Internet connection), an application activation function, or the like. Since there are various functions depending on other manufacturers, a plurality of functions are usually assigned to any function key. 2A includes a “character input key” (not shown) for inputting a telephone number 0 to 9 or characters. None of these character input keys are used in the input method.

  When the user accesses a member-based Web site (for example, a site of a financial institution), a password input screen as shown in FIG. 2A is displayed. When the user inputs the contractor number (login ID) from the contractor number input field 30 on the screen of FIG. 2A and then selects the password input field 40, the password number input of FIG. 2B is entered. A screen is displayed. Here, the numbers from “0” to “9” are displayed in order of 10 digits in each of the rows 50a to 50d. Each row corresponds to one digit of the code number, and this figure shows that the input of a four-digit code number is requested. In this figure, the same number sequence is arranged in each of the rows 50a to 50d, but the arrangement of the numbers in each row may be different. For example, 50a is "01234456789", 50b is "98776543210" in reverse order, and so on.

  The user first moves the cursor from the line 50a to the position of the first digit of the personal identification number by using the cross key 10, and erases the number by pressing the clear key 13. For example, when “1” is deleted, the row 50a is displayed as “02345789” as indicated by 51a in FIG. Similarly, “2”, which is the second digit of the code number from the line 50b, “3”, which is the third digit of the code number from the line 50c, and “4” which is the fourth digit of the code number from the line 50d. Is deleted, the rows become as indicated by 51b to 51d in FIG. That is, a string of numbers in which only specific numbers are deleted is displayed, and “1234” is input as the password.

  Thereafter, when the user presses the confirmation button 60 on the screen, this “1234” is transmitted to the authentication server 100 as a personal identification number. The confirmation button 60 does not exist as an actual key, and may represent a key function at a corresponding position. In this example, the center key 11 corresponds (hereinafter, simply referred to as “confirmation key”). In order to cancel the entered password, the key corresponding to the cancel button 61 on the screen (in this example, the camera mode key 17 corresponds to this and will be simply referred to as “cancel key” hereinafter) is pressed. , You can start over from the beginning.

  This figure shows the case where the password number is four digits, but the same is true even if the number of digits of the password number increases. If the personal identification number is 6 digits, the number of lines displayed is also 6. A password with an arbitrary number of digits can be easily obtained simply by operating the cross key 10 and the clear key 13 (erase button). Also, since the entered password disappears from the screen and is not displayed, it can be difficult to read even if another person looks into the screen. On the other hand, the input person can easily confirm the input number from the sequence of the number sequence on the screen of FIG. 2 (c), and is intuitive and easy to operate because the sequence number column corresponds to the digit number. .

  Alternatively, the display frame of the PIN code is set to one line, and the display of the input line is switched every time the confirmation key is pressed. In the case of a 4-digit password, the thousandth digit is displayed in the first display, and the next display is hundreds. It is also possible to sequentially display the display assignment destination, such as the tenth place in the next display, the first place in the last display, and the first place. In this way, the screen area other than the display frame for the personal identification number can be used for displaying other information.

  FIG. 3 is a diagram showing another example of the password input screen according to the first embodiment (embodiment 1) of the present invention. The numbers displayed in FIG. 2B are arranged in order according to a predetermined rule such as “012345789”. In this example, as shown in FIG. The arrangement of numbers in the 50d line is random. However, it is assumed that only one same number appears in one line. When “1”, “2”, “3”, and “4” are deleted from the respective rows in FIG. 3B as the passwords as in the previous diagram, as shown in 52a to 52d in FIG. 3C. Become. That is, a string of numbers in which only specific numbers are deleted is displayed. In this way, it is possible to make it difficult to read the erased numbers even if other people look into the screen than in the case of FIG. In this example, the same number is one for each row of random numbers, but two of the same numbers can be displayed. For example, a random number sequence from 0 to 9 may be continuously displayed twice such as “0412367589 0412367589” to make it difficult for others to read.

  FIG. 4 is a flowchart showing a password input process flow according to the first embodiment (embodiment 1) of the present invention. This processing flow is a processing procedure performed by executing a corresponding input program by the CPU of the terminal device 200 or the portable terminal 210 when inputting the personal identification number.

  First, in step S10, a number string corresponding to the number of digits of the password is displayed on the screen. The number of digits of the password may be different for each user (for each login ID). Next, in step S11, the numbers in each sequence row are rearranged, and the positions of the numbers after the rearrangement are stored. This rearrangement may be such that the numbers in each row are separated using random numbers, or only the rules for the order of the numbers in each row may be changed. For example, in row 1, “01234456789” (normal order), in row 2, “23456778901” (normal order starting from 2), in row 3, “98765423210” (reverse order starting from 9), and in row 4, “05162733849” (An odd number and an even number are alternately in normal order). Of course, there is an option of not rearranging.

  When the display of the above screen is completed, it is determined in step S12 whether the cursor is in any number sequence. If the cursor is in the numerical sequence, the process moves to step S13, and it is determined whether or not the clear key has been pressed. If the clear key is pressed, the number at the position where the clear key is pressed is stored (step S14), the number at that position is deleted, and the cursor is advanced by one character (the sequence is shifted to the left by one character) (step) S15). If it is determined in step S12 that the cursor is not in the sequence row or the clear key is not pressed, the process proceeds to step S19 to check whether the cancel key is not pressed. If the cancel key is pressed, the process is terminated and an opportunity for reprocessing is waited. If the cancel key has not been pressed, the process returns to step S12 again.

  After the processing in step S15, it is determined in step S16 whether or not all rows have been processed. If processing for all rows has been completed, it is further determined whether or not the confirmation key has been pressed (step S17). If the confirmation key is pressed, the erased numbers in each line are stored as a password (step S18), and then transmitted to the authentication server 100. Note that if all the rows have not been processed in step S16, or if the confirmation key has not been pressed in step S17, the process returns to step S12.

  In the description of the first embodiment shown in FIGS. 2, 3 and 4, the rows of the numeric strings correspond to the digits of the security code numbers. You may make it recognize as a number. That is, if “1” is deleted in row 4, “2” is deleted in row 3, “3” is deleted in row 2, and “4” is deleted in row 1, the password is “1234”. Alternatively, one large number string may be displayed on the entire screen side by side with a random number or a predetermined rule, and numbers at arbitrary locations may be sequentially deleted to obtain a password. In any of the above cases, the erased order is stored, and the erased numbers arranged in that order are recognized as the personal identification number.

  FIG. 5 is a diagram showing an example of a password input screen according to the second embodiment (embodiment 2) of the present invention. When the user inputs the contractor number on the screen of FIG. 5A and selects the password screen input field, the password input screen of FIG. 5B is displayed. On the screen of the second embodiment, slider display fields as indicated by 53a to 53d are displayed under each numeric string. The user can select a number to be erased by moving the slider (cursor) displayed here to the left or right using the cross key 10.

  It is the same as in the first embodiment that the erased number becomes a personal identification number. However, even if the clear key 13 is not pressed every time on each line, the cursor position on all the lines is designated with this slider, and then the clear key 13 is pressed only once. Thus, all the selected numbers may be deleted (recognized as a password). Further, as shown in FIG. 5C, the display of this slider may disappear once when the clear key 13 is pressed, and may be displayed again when the clear key 13 is pressed again. After the user confirms that numbers have been selected in all rows at the position of the slider, the password is transmitted by pressing the confirmation key.

  FIG. 6 is a diagram showing one configuration of a mobile phone according to a second embodiment (embodiment 2) of the present invention. As described in the previous figure, in the second embodiment, a slider display field indicating the position of the cursor is provided on the personal identification number input screen to make it easier to select a number. In addition, the slide switch 20 provided in the mobile phone as shown in FIG. That is, the position of the cursor is moved by moving the slide switch 20 left and right in the slide area 21. By doing so, it is possible to use the arrow keys in the vertical direction of the cross key 10 to select characters more easily. For example, a line is selected with the vertical arrow key of the cross key 10 and a character to be erased is selected with the slide switch 20. If you use both hands, you can select the vertical direction and the horizontal direction at the same time. This is more advantageous as the number of digits of the code number increases and the number of lines to be selected increases.

  Such a slide switch 20 is not only used for inputting a personal identification number, but also for adjusting the volume of the built-in speaker, adjusting the brightness of the liquid crystal screen, high-speed scrolling in the horizontal (or vertical) direction of the screen, zoom function of the built-in camera, etc. Since it can be used for various other purposes, it is also useful as a new input interface for mobile phones. The slide switch 20 may be provided on either the left or right side of the mobile phone and operated with a thumb or the like, as shown in FIG.

  FIG. 7 is a diagram showing an example of a password input screen according to the third embodiment (embodiment 3) of the present invention. In the first embodiment and the second embodiment, the password number only with numbers is taken up. However, in the following embodiments, it is shown that the present invention can be applied to the input of a password that handles not only numbers but also other characters. The screen example will be described using the example of the mobile phone. However, the function key functions are different from those shown in FIG.

  In this embodiment, when the user inputs a login ID and selects a password input field, a screen as shown in FIG. 7A is displayed. However, here, the password is assumed to be 6 characters. Each of the character string lines 55a to 55f in FIG. 7A includes not only numbers but also 26 alphabetic characters in order. However, since all characters cannot be displayed on one line because of the screen size, You can scroll left and right by pressing the left and right triangle keys. In addition to numbers and alphabets, symbol characters such as “!” And “#” may be added (except symbols that cannot be used as passwords). Here, for example, when “AKX123” is to be input as a password, the second line is first scrolled to the right so that “K” is displayed, as shown in line 56b of FIG. 7B. Next, the third row (row 56c) is scrolled to the right so that "X" is displayed. For the other lines (55a, 55d, 55e, 55f), since the corresponding characters “A”, “1”, “2”, “3” are already displayed on the screen, there is no need to scroll them.

  When all the characters used in the password are displayed on the screen in this way, the cursor is moved by using the cross key 10 in each line, and the clear key 13 is pressed at that position to sequentially change the characters to be used as the password. to erase. When all characters are erased, the result is as shown in FIG. The password is confirmed and transmitted by pressing the confirmation key in this state, as in the first embodiment. In FIG. 7, all alphabets are uppercase letters, but uppercase and lowercase letters can be used in combination, for example, by using an uppercase / lowercase switching key (referred to as A / a key 12) that is normally provided in a mobile phone. . The A / a key 12 is a key for switching between uppercase and lowercase characters during character input, and is often used also as the call start key 12 as shown in FIG. That is, when the A / a key 12 is pressed at the alphabetical position of each character string row on the password input screen, the upper case letter can be switched to the lower case letter.

  In this example, when all the character strings could not be displayed on one screen, horizontal scrolling was performed. However, all the characters that can be entered are displayed in the display frame on the screen. Each time one character input is confirmed, the display frame may be switched.

  FIG. 8 is a diagram showing an example of a password input screen according to the fourth embodiment (embodiment 4) of the present invention. In this embodiment, a method for inputting a password including characters other than numerals will be described. As shown in the drawing, in this password input screen, each character string is displayed in order by dividing the block into each character type of numbers, uppercase letters, lowercase letters, and symbols.

  The user moves this character block and inputs a password for each character type. To move between the character blocks, the up and down arrow keys of the cross key 10 or the “character input mode key 16” is used. “Character input mode key” is a key for switching the character input mode such as “Kanahan”, “English half”, “Several half”, “Kanzen”, etc. It can also be used as a function to switch blocks.

  Here, for example, consider the case where “Abc # 123” is input as the password. First, when moving to the capital letter block 57b of FIG. 8 (A) and pressing the clear key 13 at the position of “A”, a capital letter block 58b of FIG. 8 (B) is obtained. The erased “A” disappears from the original position, but is displayed as indicated by an underline at the end of the English capital letter block 58b. The reason for not completely erasing is that “A” may be designated subsequently. Subsequently, when the same operation is performed on the lower-case letter block 57c and the symbol block 57d, “bc” and “#” are displayed as indicated by 58c and 58d in FIG. 8B. Further, when moving to 57a and erasing “123”, the result becomes 58a in FIG. However, it is assumed here that characters are entered in the order of deletion. For example, if the number block 57a is erased in the order of “123”, this becomes a sequence of characters of the password. In this way, the input of “Abc # 123” is completed. In this screen, the uppercase / lowercase block 57b and the lowercase / lowercase block 57c are displayed separately. However, when the uppercase / lowercase switch key (A / a key 12) is provided, 57b and 57c are displayed in one block. You may do it.

  Since the password is not confirmed until the “confirmation key” (not shown) is pressed, after this, for example, the process returns to 58b and “B” is deleted, and the password becomes “Abc # 123B”. In the case of correcting the password, it is assumed that a “cancel key” (not shown) is pressed and entered again from the beginning. In this way, an arbitrary character string can be input as a password without pressing the “character input key”. The erased characters are displayed at the end of the character block. However, even if another person looks into this screen, it is not easy to determine which character is pressed in what order.

  FIG. 9 is a diagram showing an example of a password input processing flow according to the fourth embodiment (embodiment 4) of the present invention. This processing flow is a processing procedure performed by the CPU of the terminal device 200 or the portable terminal 210 when inputting a password.

  First, in step S20, numerals, uppercase letters, lowercase letters, and symbols are displayed in character blocks divided by character type. Next, in step S21, it is determined whether the cursor is in any character block. Further, in step S22, it is determined whether or not the clear key 13 has been pressed. If the clear key is pressed, the character at the position where the clear key 13 is pressed is stored in step S23. At this time, the order in which the clear key is pressed is also stored. If it is determined in step S21 that the cursor is not in the character block or the clear key 13 is not pressed in step S22, the process proceeds to step S27, where it is determined whether the cancel key is pressed, and the cancel key is pressed. If so, the process ends.

  When the process of step S23 is completed, the process proceeds to step S24, where the character at the position where the clear key 13 is pressed is deleted, the character is additionally displayed at the end of the character block, and the cursor is positioned at the character position. When the clear key 13 is pressed again for the additionally displayed character, the character is further recognized as a password character and additionally displayed at the end of the character block. In step S25, it is determined whether or not the confirmation key has been pressed. If the confirmation key is pressed, the process proceeds to step S26, and the characters are stored as an input password in the order in which the clear key 13 is pressed. Thereafter, the input password is transmitted to the authentication server 100. Until the confirmation key is pressed, the process returns to step S21 to accept additional input of password characters.

  FIG. 10 is a diagram showing another example of the password input screen according to the fifth example (Example 5) of the present invention. In the first to fourth embodiments, it has been shown that the password or the password character is input by deleting the character. However, in the fifth embodiment, the character is not deleted (Delete) but inserted (Insert). Shows that you can enter the password in the same way.

  The password input screen in FIG. 10 (A) is the same as that in FIG. 8 (A), but the lowercase letter block is omitted (if uppercase letters are used, the uppercase / lowercase letter switching key is used). Here, consider the case where “TANAKA @ 2011” is input as the password. First, when the user moves the cursor to the English capital letter block 57b and presses the clear key 13 at the position "T", "T" is inserted to the left of the character "T". In this case, the clear key 13 plays the role of an insertion key (Insert key), not an erasure. Of course, if an insertion key is mounted, it may be used.

  Subsequently, when the “clear key” is pressed in this order for “A”, “N”, “A”, “K”, and “A” in the same uppercase letter block 57b, FIG. As shown by 59b. That is, “T”, “N”, and “K” are input once, “A” is input three times, and the “clear key” is input in the order of pressing. Similarly, when “@” is selected in the symbol block 57c and “2”, “0”, “1”, “1” are sequentially selected in the number block 57a, the displayed character string finally becomes As shown in FIG. That is, the password “TANAKA @ 2011” is input. After that, when a confirmation key (not shown) is pressed, it goes without saying that the password is confirmed and transmitted to the authentication server 100.

  By doing in this way, it becomes easier for the user to confirm the input character than when the selected character moves to the end of the character block as shown in FIG. You may make it use properly depending on the case.

  FIG. 11 is a diagram showing another example of the password input processing flow according to the fifth embodiment (embodiment 5) of the present invention. This figure shows the processing flow on the input screen of FIG. 10, but only the processing flow of FIG. 9 and step S24a are different. That is, in step S24a, instead of deleting the character at the position where the clear key 13 is pressed, the same character is inserted to the left and the cursor position is returned to the left by one character. (See underlined characters in FIG. 10). The other steps are exactly the same as those in FIG.

  In the fifth embodiment of FIGS. 10 and 11, the characters in the character string are not “erased” but “inserted”. In this case, the entered character remains on the screen, but since the character is simply a large number of characters arranged in a plurality of character strings, the password is not easily detected even if the character is looked into the screen. Further, the “deletion” and “insertion” may be combined with further contrivance. In other words, erasure may be performed with the clear key, insertion may be performed with another appropriate key, and the character at that position may be recognized as a password regardless of which key is pressed.

  In the above embodiments, the mobile phone screen has been described as an example. However, even in the case of a terminal device such as a PC, only the screen size is different, and a similar method for inputting a personal identification number or the like is possible. is there. In the case of a PC, the “cross key 10” described in each embodiment corresponds to “←”, “→”, “↑”, “↓” (arrow keys) or a mouse on the keyboard, and the “clear key 13” is In the keyboard, the “Delete key” (in the case of the first to fourth embodiments) or the “Insert key” (in the case of the fifth embodiment), the “confirmation key” can be replaced with the “Enter key” of the keyboard. Recently, there are many softwares for emulating a mobile phone screen on a PC screen. By using such software, the same user interface can be used on a PC.

  As mentioned above, although this invention was demonstrated using embodiment (Example), it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. Further, it is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
