Description

  The present invention relates to an output information processing technique, and more particularly to a process of outputting output information corresponding to input data in order to suppress input errors (typing errors) in an input operation in which input data is kept secret.

  As an input operation for concealing the display of input data, for example, an input operation for echoing an input password is known.

  When a user inputs a combination of letters, numbers, symbols, and the like (hereinafter simply referred to as a character string) as a password, echo characters such as black circles and asterisks are displayed instead of the entered letters. If the character string entered under the echo display is not authenticated as a password, a re-entry operation is prompted, but when the input operation reaches the specified number of times, subsequent user operations are rejected or the password is invalidated. Is processed.

  Simple typos in input operations occur quite often. However, if the input data is concealed, the user cannot confirm during the input operation whether the user has made a typo, so he / she is not aware of the typo and tries to perform the following operations with the entered password. , It may cause the above-mentioned operation rejection and password invalidation.

  For this reason, a reference set value for output data corresponding to the user identification information (user ID) is held, and the output set value of the output data is calculated using the input data and the reference set value. Correspondingly, there is provided a method of changing the output setting of output data and performing a process of outputting so that the user can recognize a typo in an input operation in which the input data is concealed.

  In addition, when the user's past viewing patterns are stored as history information and the video and audio of the input source provided from multiple media are output simultaneously, the user's preference is based on the stored history information. A method for determining the viewing mode of an input source is provided.

  Also, when there is user input, the input state of the object corresponding to the input data item is transitioned, and the inference engine is driven using this transition as a trigger, and based on the rules describing the mutual relationship between the data items, There is provided a method for displaying data items that can be input on the screen to prevent erroneous data items from being input.

  As a password that is a typical example of confidential input data, it is common for a user to use different character strings for each business system to be used, and it is also preferable from the viewpoint of security.

  In the conventional method, the output data (for example, display color) can be displayed based on the output setting corresponding to the input data (for example, password). Can be recognized by the transition pattern.

  However, when multiple different character strings are used as passwords, the display color transition pattern differs for each character string used as the password, so the user must remember the password and the display color transition pattern in pairs. There must be. Then, after storing the correct display color pattern corresponding to the input password, it is necessary to determine whether the displayed pattern is different. Since such a determination becomes more difficult as the number of passwords increases, there is a problem in that the more a password that is preferable for security is used, the more difficult it is to notice a typo during an input operation.

  An object of the present invention is to use the conversion information indicating the output information corresponding to the input position of the input character so that the input character corresponds to the conversion information when outputting the output information corresponding to the input of the character. It is to realize output information processing that can output constant output information as long as it is a character of a character string.

Te, from the character code value of each character in the Rubeki string is input to the second input region corresponding to the identification information, the output value indicating the output information of the output information pattern output in response to said each character the conversion value to, by referring to the conversion information storage unit for storing those set according to the order of characters in the string, N-th the second input region (N is a natural number of 1 or more) input to And character code values of the characters, the output information by using the said N-th converted values set in the conversion information for the identification information input to the first input area, and outputs the N-th as the output information pattern an output value calculating step of calculating an output value of, by referring to the output information storage unit for storing the output information for each of a plurality of different output values, the decision output information for determining the output information corresponding to the N-th output value And an output step for outputting the determined output information to a display screen for displaying the second input area as the output information pattern .

  According to the above disclosed method, as long as the Nth character input in the input area is a character string corresponding to the conversion information stored in advance, it corresponds to the input of the Nth character. Certain output information is output. Therefore, the user can confirm whether the correct character string has been input from the output information corresponding to the character even when using different character strings, for example, as passwords. It can be easily recognized.

  First, an output information processing method disclosed as an embodiment of the present invention will be described.

  In the present embodiment, a computer that executes the disclosed output information processing method (hereinafter referred to as a server) supports character input in an input operation that is executed by a computer used by a user (hereinafter referred to as a client). To execute output information output processing.

  The output information is a display color or pattern displayed corresponding to the input character.

  The output information is defined in association with a plurality of different output values. For example, if the output information is a display color, the output value may be an RGB set value, a value indicating hue / lightness / saturation, or the like, or if it is a pattern, a value indicating a prepared pattern, etc. , Defined as an output value.

  Corresponding to the input of each character of the character string, information indicating any plurality of output information having order is set as an output information pattern. The output information pattern is automatically determined on the server side based on a reference character string (hereinafter referred to as a reference character string) specified by the user, or specified by the user.

  The reference character string is one character string designated by the user among character strings input to an input area that is associated with user identification information and whose display is concealed (hereinafter, “confidential character string”).

  FIG. 1 is a diagram illustrating an example of a screen displayed on the client.

  A screen 100 shown in FIG. 1 is an example of a login screen that performs authentication processing by identifying a user who can use a certain business system by a login ID and a password.

  The screen 100 includes a first input area 110, a second input area 120, and a display unit 130.

  The first input area 110 is an area into which a character string indicating user identification information (for example, login ID) for identifying the user in the system used by the user is input. The second input area 120 is an area where a secret character string (for example, a password) corresponding to the user identification information is input.

  The display unit 130 is an area where output information corresponding to the characters input in the second input area 120 is output. In this embodiment, the output information is the display color of the display unit 130 of the screen 100, and the output value is a set of RGB R, G, and B values indicating the display color (hereinafter referred to as RGB values). .

  The display unit 130 may be provided as the entire background portion of the screen 100.

  FIG. 2 is a diagram for explaining a conversion information generation process example used in the disclosed output information processing method.

  First, the conversion information generation process of FIG. 2 will be described.

  Step S1: The server acquires either a reference character string or an output information pattern designated by the user as information for generating conversion information from the client. The initial output information that is the display color of the initial state of the display unit 130 may be acquired together with the reference character string.

  Step S2: The server acquires a secret character string specified by the user.

  Step S3: Based on the character code value of each character of the secret character string acquired in step S2, the server calculates a conversion value to an output value indicating output information output corresponding to the input of the character. , Generating and storing conversion information indicating the calculated conversion value in correspondence with the character arrangement order of the acquired secret character string.

  Next, an example of generation processing when an output information pattern is specified by the server will be described.

  Based on the secret character string and the reference character string, the server sets the character code value of the Mth character (M is a natural number of 1 or more) of the secret character string and the character code value of the Mth character of the reference character string. And character code difference information indicating the calculated character code difference value in association with the arrangement order of characters in the secret character string is generated.

  As an example, it is assumed that the server acquires the reference character string “s1, s2, s3, s4” and the secret character string “x1, x2, x3, x4”. In addition, the display color D0 (output value d0) in the initial state of the display unit 130 is used.

The server first outputs output indicating the next output information based on the output value d0 indicating the display color D0 in the initial state and the character code value (value indicating the character code) c _s1 of the character s1 of the reference character string. A value d1 (display color D1) is obtained. Similarly, the server obtains the next output value d2 (display color D2) based on the output value d1 and the character code value c s2 of the character _s2, and the character code value c _s3 of the output value d2 and the character s3. Next, the next output value d3 (display color D3) is obtained, and the next output value d4 (display color D4) is obtained based on the output value d3 and the character code value c _s4 of the character s4.

  When the characters of the reference character string “s1, s2, s3, s4” are sequentially input to the second input area 120, the server displays the display colors D0 → D1 → D2 → D3 → D4. The information is displayed in order, and the user confirms the output information pattern when the secret character string registered in the second input area 120 is input.

Further, the server determines the character code value of the Mth character (M is a natural number of 1 or more) of the character string of the secret character string “x1, x2, x3, x4” and the reference character string “s1, s2, s3, s4”. The difference value (character code difference value) from the character code value of the Mth character is calculated. That is, the difference value d _x1 (d _x1 = c _s1 −c _x1 ) of the code value c _x1 of the character x1 with respect to the character code value c _s1 of the character _s1 , and the code value c _x2 of the character x2 with respect to the character code value c _s2 of the character _s2 calculating a difference value dx2, the difference value dx3 code value _{c x3} character x3 for the character code value _{c s3} character s3, the difference value dx4 code value _{c x4} character x4 for the character code value _{c s4} character s4 respectively .

Then, the server generates character code difference information “d _x1 , d _x2 , d _x3 , d _x4 ”, and stores it in association with the corresponding user identification information.

  FIG. 3 is a diagram illustrating an example of character code difference information.

  In the character code difference information, system information and a sequence of character code difference values are set in association with the user identification information.

  The system information is information indicating a system in which the user identification information is used. For example, the system information is indicated by information (URL) indicating a storage location of the system login screen.

  In the character code difference information shown in FIG. 3, the character string “s1, s2, s3, s4 (character code value in decimal notation = 75, 76, 77, 78)” corresponding to the login ID = ID 1234 is the reference character string. Yes, "0, 0, 0, 0" is set as the sequence of character code difference values. For the secret character string “x1, x2, x3, x4 (character code value = 82, 81, 80, 79)” corresponding to the login ID = ID1357, the character code difference value “−7, -5, -3, -1 "is stored.

  Next, an example of generation processing when the output information pattern is specified by the user will be described.

  The server obtains an output value indicating the Mth output information of the output information pattern acquired in step S1 from the character code value of the Mth character (M is a natural number of 1 or more) of the secret character string acquired in step S2. Calculate the output conversion value. Then, the server generates output conversion information indicating the calculated output conversion value in association with the sequence of characters in the secret character string.

  As an example, it is assumed that the server acquires the output information pattern “D6, D7, D8, D9” and the secret character string “y1, y2, y3, y4”. In addition, the display color D0 (output value d0) in the initial state of the display unit 130 is used.

Server, display color D0 from the sum of the character code value _{c y1} of output value d0 and characters of the string y1 indicating the value which the output value d6 showing the display color D6 determined (output conversion _value) d y1 _{(d y1} = d6- (c _x1 + d ₀ )) is obtained. Similarly, the server, the character code of the output value d6 output value d7 is determined value indicating the display color D7 from the sum of the character code value _{c y2} character y2 (output conversion _{value) d y2,} the output value d7 and character y3 from the sum of the sum of the values _{c y3,} display color D8 determined output value d8 indicating the value (output conversion _{value) d y3,} the character code value _{c y4} output value d8 character y4, output indicating a display color D9 value d9 is determined value (output conversion _{value) d y4,} respectively obtained. Here, since the output value indicating the display color is a set of RGB values (R value, G value, B value), an output conversion value for each value (R value, G value, B value) is calculated. The

Then, the server generates output conversion information “d _y1 , d _y2 , d _y3 , d _y4 ”, and stores the output conversion information in association with corresponding user identification information.

  FIG. 4 is a diagram illustrating an example of an output information pattern set by the user.

  As shown in FIG. 4A, an output value d6 (R value = 187, G value = 224, B value) indicating the display color D6 as an output information pattern set in the order of display colors D6, D7, D8, D9. = 227), output value d7 indicating display color D7 (R value = 255, G value = 204, B value = 153), output value d8 indicating display color D8 (R value = 204, G value = 153, B value) = 255), an output value d9 (R value = 255, G value = 153, B value = 204) indicating the display color D9 is acquired.

  The server associates the acquired output information pattern with the output order (SEQ) in the output information pattern, as shown in FIG. 4B, and outputs the Nth output value (R value, G value, (B value) is converted into output values (CODE-R, CODE-G, CODE-B) indicating the output information expressed by the difference from the (N-1) th output value and held.

  FIG. 5 is a diagram illustrating an example of output conversion information.

  In the output conversion information, an output conversion value from which an output value indicating the output information is obtained according to the order of the output information indicated in the output information pattern is stored.

  The example of the output conversion information shown in FIG. 5 is for each character in the case of the character string “y1, y2, y3, y4 (character code value = 65, 66, 67, 68)” corresponding to the user identification information (ID 2468). An output conversion value for converting the character code value is converted into an output value indicating the output information pattern shown in FIG.

For example, the output value of the output information in the initial state in the case of the "0,0,0", adds the string "y1, y2, y3, y4" character code value _{c y1} 1 th character of the output The output conversion value d _y1 (dy1−R = 122, dy1−G = 159) that becomes the output value d6 (CODE−R = 187, CODE−G = 224, CODE−B = 227) set to SEQ = 1 of the information. , Dy1−B = 162) is set.

  In the conversion information generation process described above, the calculation formula used in the process of calculating the output value indicating the output information from the character code difference information, or the calculation used in the process of calculating the output conversion value from the output value of the output information pattern Expressions can be complicated from a security perspective.

  After the conversion information generation processing, when a character is input to the second input area 120 of the screen 100, the server performs output processing of output information corresponding to the character input.

  FIG. 6 is a diagram for explaining an output processing example of output information corresponding to character input.

  Step S10: The server acquires user identification information input in the first input area 110 of the screen 100.

  Step S11: The server specifies conversion information corresponding to the user identification information. Also, the output value indicating the display color of the display unit 130 is initialized.

  Step S12: When a character is input to the second input area 120 of the screen 100, the server acquires the input Nth character.

  Step S13: The server uses the Nth conversion value set in the conversion information based on the character code value of the Nth character input in the second input area 120, and outputs the Nth output value. Calculate

  Step S14: The server determines output information corresponding to the Nth output value as the output information of the Nth character input to the second input area 120.

  Step S15: The server outputs the determined output information to the display unit 130 of the screen 100.

  More specifically, in the process of step S13, the server refers to the character code difference information, and adds the character code value corresponding to the user identification information to the character code value of the Nth character input to the second input area 120. The Nth output value is obtained by adding or subtracting the Nth character code difference value of the difference information.

For example, when the first character x1 is input to the second input area 120, the first difference value d _x1 of the character code difference information is added to the character code value c _x1 of the input character x1, Based on the current output value (output value d0 of display color D0 in the initial state) and the character code value converted by the character code difference value (c _x1 + d _x1 = c _s1 ), the Nth output value is decide.

In this case, even if the character input to the second input area 120 is x1, the character code value c _x1 of the input first character _x1 is set to the character s1 of the reference character string by the character code difference information. Since the character code value c _s1 is converted, the output value d1 is obtained. As a result of the processing in step S15, the same display color D1 as that when the reference character string s1 is input is displayed on the display unit 130 of the screen 100.

Similarly, even when the character x2 is input to the second input area 120, the character code value c _x2 of the input second character _x2 is determined as the reference character string by the character code difference information in the process of step S13. The character is converted to the character code value c s2 of the character _s2 , and is added to the display color (output value d1) output corresponding to the input of the previous character x1 to obtain the output value d2. As a result of the processing in step S15, the same display color D2 as that when the reference character string s2 is input is displayed on the display unit 130.

  Therefore, as long as the character string in which the character code difference information is generated is input in advance, the output information that is the same as the input of the character of the reference character string is output, so the user can input to the second input area 120. Whether or not the correct character is correct can be confirmed by the display color displayed on the display unit 130.

  Alternatively, in the process of step S13, the server refers to the output conversion information, adds the character code value of the Nth character input to the second input area 120 to the N of the output conversion information corresponding to the user identification information. The Nth output value is calculated by adding or subtracting the ith output conversion value.

For example, the second input region 120, the first character y1 is input, the character code value c _y1 character y1 entered, by adding the first output conversion value d _y1 of the output conversion information obtained The Nth output value is determined by the obtained value (c _x1 + d _y1 + d ₀ = d6).

In this case, the character code value cy1 whose character input to the second input area 120 is _y1 is converted into an output value d6 indicating the first output information of the output information pattern by the corresponding output conversion value. As a result of the processing in step S15, the display color D6 designated by the user is displayed on the display unit 130 of the screen 100. Similarly, when the character y2 is input to the second input area 120, the output information (output value d6) corresponding to the character y1 input immediately before and the character code of the input second character y2 Since the output value d7 is obtained from the value c _x2 and the output conversion value, the next D7 is displayed on the display unit 130.

  Therefore, as long as a character string for which output conversion information is generated is input in advance, the same display color as the specified output information pattern is output in the specified order. Whether or not the input character is correct can be confirmed by the display color displayed on the display unit 130.

  Next, a process of generating character code difference information when the number of characters of the secret character string acquired in the process of step S2 is different from the number of characters of the reference character string will be described.

  In the process of step S3, when the number of characters of the acquired secret character string is smaller than the number of characters of the reference character string, the server uses the character code value of the last character of the acquired character string to calculate each character of the reference character string. Calculate the corresponding character code value.

  For example, the reference character string is “A, B, C, D (character code value = 65, 66, 67, 68)”, and the acquired character string is “C, B, A (character code value = 67, 66, 65) ", the server obtains the character code difference value" -2, 0, 2 "for the first to third characters. Further, a character code difference value “3” between the last (third) character of the secret character string and the fourth character of the reference character string is obtained, and a character code difference of “−2, 0, 2/3” is obtained. Generate information. “2/3” indicates that two output values are determined using two character code difference values “2” and “3” in order corresponding to the input of the third character.

  Conversely, if the number of characters in the acquired character string is greater than the number of characters in the reference character string, the code value of that character is 0 for the characters in the acquired character string that do not have a corresponding character in the reference character string. Find the character code difference value.

  For example, the reference character string is “A, B, C, D (character code value = 65, 66, 67, 68)”, and the acquired secret character string is “E, D, C, B, A (character When the code value = 69, 68, 67, 66, 65) ”, the server obtains the character code difference value“ −4, −2, 0, 2 ”for the first to fourth characters. Further, a value in which the fifth character code value of the secret character string is 0 is set as a character code difference value. Here, since “−65”, the character code difference information “−4, −2, 0, 2, −65” is generated.

  Therefore, even if the number of characters in the secret character string and the reference character string is different, as long as the correct character is input as the secret character string, it is displayed in the same display color pattern. It becomes easy to notice typos.

  Next, first to fifth configuration examples will be described as configuration examples of the output information processing system that performs the output information processing method.

  In the processing according to the first to fifth configuration examples, the user identification information input to the first input area 110 of the screen 100 is, for example, a login ID, and the character string input to the second input area 120 is, for example, , Password. The output information output to the display unit 130 of the screen 100 is a display color (color information) specified by, for example, RGB values.

  FIG. 7 is a diagram illustrating a first configuration example.

  In the first configuration example, the output information processing system includes an output information processing server 1, a client 2, and a shared information management server 3.

  The output information processing server 1 is a device that determines output information corresponding to characters input on the screen 100 displayed on the client 2 and outputs the information to the screen 100.

Are stored in the character code difference value storage unit 13 in association with the user identification information.

  The character code difference value acquisition unit 14 acquires character code difference information corresponding to the user identification information received by the client 2 from the character code difference information storage unit 13 and passes it to the display color calculation unit 15.

  The display color calculation unit 15 calculates an output value corresponding to the character input to the second input unit 120 received by the client 2 based on the acquired character code difference information.

  The client 2 includes a user registration unit 21, a user identification information reception unit 22, a character string reception unit 23, a display processing unit 24, an input device 25. And an output device 26.

  The user registration unit 21 receives input of user identification information, a reference character string, and a secret character string via the input device 25, and transmits these pieces of information to the output information processing server 1.

  The display processing unit 24 displays the display color notified from the output information processing server 1 on the display unit 130 displayed on the output device 26.

  The shared information management server 3 includes a reference character string reception unit 31, a reference character string storage unit 32, and a reference character string acquisition unit 33.

  The reference character string receiving unit 31 acquires the reference character string from the output information processing server 1 and stores it in the reference character string storage unit 32.

  The reference character string acquisition unit 33 acquires a reference character string corresponding to the user from the reference character string storage unit 32 and transmits the reference character string to the output information processing server 1.

  FIG. 8 is a diagram illustrating an example of a processing flow in the first configuration example. FIG. 8A shows an example of a processing flow of character code difference information generation processing, and FIG. 8B shows an example of a processing flow of display color output processing.

  In the processing flow example of FIG. 8A, step S100 corresponds to step S1 of the processing flow shown in FIG. 2, step S102 corresponds to step S2, and steps S103 and S104 correspond to processing of step S3. .

  Step S100: The user registration unit 21 receives a reference character string designated by the user. The reference character string receiving unit 31 stores the reference character string acquired via the user receiving unit 11 in the reference character string storage unit 32 in association with the user (user information).

  Step S102: The user registration unit 21 receives user identification information and a secret character string to be processed. The character code difference value calculation unit 12 acquires the received user identification information and the secret character string via the user reception unit 11.

  Step S104: The character code difference value calculation unit 12 stores the calculated character code difference value sequence in the character code difference information storage unit 13 as character code difference information in association with the user identification information. Thereafter, the character code difference value calculation unit 12 erases the user identification information, the reference character string, and the secret character string used for the processing.

  Step S112: The character string receiving unit 23 monitors whether or not a character is input (typed in) in the second input area 120 of the screen 100. The character string receiving unit 23 waits until a character is input in the second input area 120. When a character is input in the second input area 120 (Y in step S112), the process proceeds to step S113.

  Step S113: When a character is input to the second input area 120, the character string receiving unit 23 acquires the Nth character.

  Step S114: The display color calculation unit 15 calculates the Nth output value for the Nth character acquired by the character string reception unit 23, using the Nth character code difference value of the character code difference information. Further, based on the calculated output value, the Nth display color corresponding to the input of the character is determined and notified to the display processing unit 24.

  Step S115: The display processing unit 24 displays the notified display color on the display unit 130 of the screen 100.

  In the case of the first configuration example, since the reference character string and the character code difference information corresponding to the secret character string are stored in different servers, the reference character string and the character code difference information are leaked simultaneously, The risk that a secret character string is estimated can be reduced.

  FIG. 9 is a diagram illustrating a second configuration example.

  In the second configuration example, the output information processing system includes an output information processing server 1a and a client 2a.

  In the configuration examples after the second configuration example, the processing units given the same reference numerals as the processing units shown in the first configuration example in the figure perform substantially the same operations as the corresponding processing units. is there.

  Step S121: The character code difference value calculation unit 12a calculates a character code difference value based on the character code value of each character of the secret character string and the character code value of the corresponding character of the reference character string.

  Step S122: The character code difference value calculation unit 12a stores the calculated character code difference value sequence in the character code difference information storage unit 13 as character code difference information in association with the user identification information. Thereafter, the character code difference value calculation unit 12a deletes the user identification information, the reference character string, and the secret character string used for the processing.

  Since the output information output process in the second configuration example is the same as the process described in the first configuration example (see FIG. 8B), the description is omitted.

  In the case of the second configuration example, every time the character code difference information corresponding to the secret character string is generated, it takes time to input the reference character string. However, since the reference character string is not stored, the reference character string and the character are not stored. The risk that the code difference information is leaked at the same time and the secret character string is estimated can be further reduced.

An output conversion value for obtaining an output value indicating information is calculated.

  Step S133: The output conversion value calculation unit 16 stores the calculated sequence of output conversion values in the output conversion information storage unit 17 in association with the user identification information as output conversion information. Thereafter, the output conversion value calculation unit 16 deletes the user identification information, the output information pattern, and the secret character string used for the processing.

  Step S150: The output information pattern acquisition unit 27 acquires the output information pattern specified by the user.

  As an example, the output information pattern acquisition unit 27 displays a screen for inputting an output information pattern on the output device 26, and acquires an output value indicating each display color in the output order specified by the user as an output information pattern. .

  Alternatively, the output information pattern acquisition unit 27 displays a screen for inputting an output information pattern on the output device 26, and inputs a secret character string that has already been registered. Then, the output information pattern acquisition unit 27 transmits the input secret character string to the display color calculation unit 19, and refers to the output value indicating the display color determined by the display color calculation unit 19 based on the secret character string. Then, the output values of the display colors in the determined order are acquired as output information patterns and passed to the output conversion value calculation unit 16c.

  Step S151: The output conversion value calculation unit 16c acquires user identification information and a secret character string to be processed via the user registration unit 21c and the user reception unit 11c.
