  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a network configuration diagram for explaining an application example of the authentication system according to the present embodiment.

  In the network shown in the figure, a user side terminal 1, an image processing device (MFP: Multi Function Peripheral) 2, an MMK (Multimedia Kiosk) 3, a database 4 and a server 5 are mutually connected via an electric communication line such as the Internet. It is connected so that it can communicate. The user side terminal 1 is, for example, a PC or the like owned by the user at home. The MMK 3 is a multi-function terminal device installed in a store that can be used by an unspecified number of users such as a convenience store. Further, the image processing apparatus 2 performs image processing such as image reading and image formation in response to a request from the user terminal 1 or the MMK 3. The server 5 provides a predetermined WEB page to the user side terminal 1, the image processing device 2 and the MMK 3 via the Internet or the like, and various kinds of requests according to requests from the user side terminal 1, the image processing device 2 and the MMK 3 It has a role to perform the process.

  Here, as for the user side terminal 1, the image processing device 2, the MMK 3, the database 4, and the server 5, the means for connecting each other so as to be able to communicate with each other is the Internet. (It does not matter whether it is wired or wireless).

  In the network shown in the figure, the user terminal 1, the image processing device 2, and the MMK 3 can perform authentication processing based on information input by user operation input and information stored in the database 4. Yes.

  FIG. 2 is a functional block diagram for explaining the authentication system according to the present embodiment.

  The authentication system according to the present embodiment includes a character string acquisition unit 101, a character input support unit 102, a timing information acquisition unit 103, an authentication processing unit 104, a reference timing teaching unit 105, a registration unit 106, a CPU 107, a MEMORY 108, a display unit 109, The audio output unit 110 and the operation input unit 111 are provided.

  In the present embodiment, the authentication system is provided in any one of the user side terminal 1, the image processing device 2 and the MMK3, and performs authentication processing in any of the user side terminal 1, the image processing device 2 and the MMK3. Have a role. Hereinafter, as an example, the function of the authentication system provided in the user terminal 1 will be described.

  The character string acquisition unit 101 is a character string (ID information such as an employee number set in advance for the user) as identification information for identifying the user during user authentication (for example, authentication processing for using the MFP 2). Etc.).

  When the character string acquisition unit 101 acquires a character string as identification information for identifying the user, the character input support unit 102 sets a predetermined timing as a reference for the input timing of the character string to the user. Teach.

  Here, the character input support unit 102 can express, for example, voice inflection or volume change timing from the voice output unit 110 (details will be described later), display color change timing on the display screen in the display unit 109, and timing. By indicating to the user the change timing of a figure such as a metronome, the blinking timing of light, the change timing of numerical values, the time, etc., it assists to facilitate the input of identification information at a predetermined input timing. FIG. 3 shows a figure that can measure timing such as a clock when inputting ID information in a window displayed on the display unit 109, thereby making it easier to grasp the timing of the user's ID input. FIG. The authentication screen as shown in the figure is displayed, for example, on the driver screen of the MFP 2 or the like.

  The timing information acquisition unit 103 acquires information on the input timing of the character string acquired by the character string acquisition unit 101 (information on the operation timing of the operation input unit 111 operated when the user inputs a character string). Specifically, the timing information acquisition unit 103 measures the input timing of the character string acquired by the character string acquisition unit 101 for the authentication process, and individual characters constituting the character string are input. The time is stored in the database 4 or the MEMORY 108.

  In the timing information acquisition unit 103, as information regarding the operation timing of the operation input unit 111 operated when the user inputs a character string, an absolute time and a character string at which an operation input of each character constituting the character string is performed are performed. Any one of the relative time intervals in which the operation input of each of the constituent characters is performed is acquired.

  In addition, the timing information acquisition unit 103 not only performs new input of characters but also moves the cursor for character input, deletes input characters, and re-enters characters in the operation input unit 111 operated when the user inputs a character string. Information on the execution timing of at least one of input and pressing of a predetermined function key is also acquired.

  As described above, the character string itself of the identification information is determined based on the finally input character string in the authentication process in the authentication processing unit 104, and the character input timing is executed until the character input is completed. By including the pressing of the specific key, information used for user authentication can be varied according to the individual user, and the security level can be improved.

  Note that the information related to the input timing of the character string acquired by the timing information acquisition unit 103 does not necessarily have to be for each character constituting the character string. For example, the time required for inputting the entire character string, It can also be set as the average time of the timing of inputting individual characters.

  The authentication processing unit 104 performs user authentication processing based on the character string acquired by the character string acquisition unit 101 and the information regarding the input timing acquired by the timing information acquisition unit 103.

  In the authentication processing unit 104, when the user is required to be authenticated, the character input support unit 101 indicates a character input reference timing. The user refers to this timing and inputs the registered predetermined ID in the same manner as the registered input timing. Authentication is permitted when the ID input by the user and the input timing thereof match the ID and input timing registered in advance.

  The reference timing teaching unit 105 has a role of indicating a predetermined timing as a reference when the identification information of the user is registered to the user. Here, as with the character input support unit 101, the reference timing teaching unit 105 displays, for example, voice inflection and volume change timing from the voice output unit 110, display color change timing and timing on the display screen of the display unit 109. The input timing of identification information at a fixed timing by showing to the user the change timing of graphics such as a clock or metronome (see FIG. 3), the blinking timing of light, the change timing of numerical values, the time, etc. Can be easily registered.

  The registration unit 106 registers in the database 4 a character string as identification information input when the predetermined timing is indicated by the reference timing teaching unit 105 and the input timing of the character string. In this way, when the user registers his / her authentication information, the user's own ID input rhythm should be registered in advance as part of the information used for authentication with reference to the reference timing indicated by the reference timing teaching unit. Can do. The authentication processing unit 104 performs the user authentication processing based on the character string registered in the registration unit 106 and the input timing of the character string.

  The CPU 107 has a role of performing various processes in the authentication system, and also has a role of realizing various functions by executing a program stored in the MEMORY 108. The MEMORY 108 includes, for example, a ROM, a RAM, and the like, and has a role of storing various information and programs used in the authentication system.

  The display unit 109 is configured by a liquid crystal display, a CRT display, or the like, and has a function of displaying the contents of processing performed in the authentication system 1. The audio output unit 110 includes a speaker or the like, and outputs voice, music, beep sound, etc. (hereinafter referred to as audio). The operation input unit 111 includes a keyboard, a mouse, and the like, and has a function of receiving a user operation input. Of course, the functions of the display unit 109 and the operation input unit 111 may be realized by a touch panel display or the like.

  Moreover, in this Embodiment, although all the components which comprise an authentication system showed the example with which the user side terminal 1 was equipped, each component which comprises the authentication system 1 can mutually communicate, It does not matter as long as it functions as a whole.

  Further, it is not always necessary to input a character string as identification information for identifying the user at the time of user authentication on the authentication processing screen set in the user side terminal 1, the image processing device 2, and the driver in the MMK 3. Instead, the configuration may be such that it is performed on a predetermined WEB page for authentication processing provided by the server 5. FIG. 4 is a functional block diagram of the authentication system when the user who operates the user terminal 1 performs the authentication process on the WEB page provided by the server 5.

  In the configuration shown in FIG. 4, the display unit 109, the audio output unit 110, and the component unit that the user actually needs to operate on the user-side terminal 1 and the component unit that has a function of performing a predetermined action on the user. An example in which all components other than the operation input unit 111 are provided in the server 5 is shown.

  Thereby, in order to perform authentication processing on the WEB page, when the user inputs ID information in the ID input field on the authentication screen, the keyboard input timing and input rhythm are acquired as data in the background. And can be temporarily stored in the database 4 or the MEMORY 108.

  In addition, when accepting input of a character string as identification information for identifying the user at the time of user authentication on the WEB page as described above, when the user completes the ID input and issues an authentication request, an ID input field In addition to the character string of the ID information input to, information regarding the input timing (rhythm) of the character string is also transmitted to the authentication processing unit 104. Here, in the case where the character string acquisition unit 101, the timing information acquisition unit 103, and the authentication processing unit 104 are provided in different devices, together with the character string of the ID information acquired on the WEB page, the character When transmitting information related to the input timing (rhythm) of the column to the authentication processing unit 104, the data to be transmitted may be encrypted and transmitted by an encryption technique such as SSL (Secure Socket Layer). .

  The ID character string and the input timing of the character string are acquired not only on the WEB page browsed by the WEB browser but also in the authentication process for accessing the MFP 2, for example, the driver of the MFP 2 ( This can also be realized by incorporating an ID character string and a mechanism for acquiring the input timing of the character string into a driver of a predetermined device.

  When the authentication system according to the present embodiment is applied to MFP 2, operation input unit 111 and display unit 109 are preferably configured by an operation panel that receives an operation input related to predetermined image processing in MFP 2, for example.

  FIG. 5 is a flowchart for explaining an outline of the flow of authentication processing (authentication method) in the authentication system according to the present embodiment. Hereinafter, for convenience of explanation, processing in the authentication system having the configuration of the functional block diagram shown in FIG. 2 will be described.

  When the user opens, for example, the MFP 2 driver screen (FIG. 6) on the display unit 109 in the user terminal 1, various setting items such as “setting”, “print”, and “personal information printing” are displayed.

  Here, for example, when the user selects “print personal information”, since the security level of the item needs to be increased, an authentication screen as shown in FIG. 3 is displayed.

  When the character string as identification information for identifying the user is acquired in the character string acquisition step (for example, when an authentication screen as shown in FIG. 3 is displayed), the character input support unit 102 The user is instructed at a predetermined timing as a reference for the input timing of the character string (character input support step) (S101).

  The character string acquisition unit 101 acquires a character string as identification information for identifying the user at the time of user authentication (character string acquisition step) (S102). The input timing teaching by the character input support unit 102 does not necessarily have to be performed prior to the acquisition of the character string in the character string acquisition unit 101. It may be performed until the character string acquisition by the character string acquisition unit 101 is completed.

  The timing information acquisition unit 103 acquires information on the input timing of the character string acquired in the character string acquisition step (information on the operation timing of the operation input unit 111 operated when the user inputs the character string) (timing) Information acquisition step) (S103). Specifically, the timing information acquisition unit 103 acquires the keyboard pressing timing when the user presses the keyboard during user authentication and inputs the identification information of the user. In this way, the timing information acquisition step uses the absolute time and character when the operation input of each character constituting the character string is performed as information related to the operation timing of the operation input unit 111 operated when the user inputs the character string. One of relative time intervals in which operation input of each character constituting the column is performed is acquired.

  The authentication processing unit 104 performs user authentication processing based on the character string acquired in the character string acquisition step and the information regarding the input timing acquired in the timing information acquisition step (authentication processing step) (S104). ). For example, at least one of the character string acquired in the character string acquisition step and the information related to the input timing acquired in the timing information acquisition step does not match the information stored in the database 4. In this case, it is determined that the authentication has failed.

  In the authentication process in the authentication process step described above, if it is determined that the input character string of the user and the input timing of the character string are valid, a personal information selection screen as shown in FIG. It is displayed on the display unit 109. On the personal information selection screen displayed in this way, the user selects a desired item such as “print salary details” or “check work status”, and performs processing such as print processing related to the desired item on the server 5. Request. The server 5 that has received the request transmits print data of the information to the MFP 2, and the user acquires a document printed by the MFP 2. It should be noted that, in order to avoid a document printed by the MFP 2 being acquired by another person, an authentication process may be required to start printing on the MFP 2.

  FIG. 8 is a flowchart showing details of processing in the authentication system according to the present embodiment. When a character is input through the operation input unit 111 (S201), the character is stored in the MEMORY 108 (S202). Then, the timing information acquisition unit 103 acquires the character input time or the character input timing (S203).

  When the character is the first character (S204, Yes), the input timing of the character is stored in the MEMORY 108 (S206). On the other hand, when the character is not the first character (S204, No), the input time or timing of the character input immediately before is compared with the input time or timing of the character (S205).

  Subsequently, when the authentication button is not pressed (S207, No) and there is no predetermined number of characters input (S208, No), the next character input standby state is entered (S209). On the other hand, when the authentication button is pressed (S207, Yes), or when a predetermined number of characters are input (S208, Yes), the authentication processing unit 104 searches the database 4 for authentication information ( S210).

  If any one of the input character string and the input time or timing of the character string does not match the authentication information stored in the database, an authentication error screen is displayed on the display unit 109 (S211, S212, S213). If both the character string and the input time or timing of these character strings match, the authentication is successful.

  FIG. 9 is a flowchart for explaining an outline of the flow of registration processing of user identification information in the authentication system according to the present embodiment.

  The reference timing teaching unit 105 indicates a predetermined timing as a reference when the identification information of the user is registered to the user (reference timing teaching step) (S301). The teaching method for the user at the predetermined timing as a reference here is the same as the teaching method at the predetermined timing as the reference for the input timing of the character string by the character input support unit 102.

  The registration unit 106 registers a character string as identification information input when the predetermined timing is indicated by the reference timing teaching step and the input timing of the character string (registration step) (S302). In the authentication processing step described above, the user authentication processing is performed based on the character string registered in the registration step and the input timing of the character string.

  Note that the character string as identification information and the information related to the input timing of the character string do not necessarily need to be acquired and registered at the same time, and may be acquired at different timings. That is, it is only necessary that these character strings and input timings can be finally registered in the database 4 in association with each other.

  Each step in the processing in the above-described authentication system is realized by causing the CPU 107 to execute an authentication program stored in the MEMORY 108.

  In this embodiment, the function for implementing the invention is recorded in advance in the apparatus. However, the present invention is not limited to this, and the same function may be downloaded from the network to the apparatus, and the same function is recorded. What is stored in the medium may be installed in the apparatus. The recording medium may be any form as long as the recording medium can store the program and can be read by the apparatus, such as a CD-ROM. Further, the function obtained by installing or downloading in advance may be realized in cooperation with an OS (operating system) or the like inside the apparatus.

  In the above example, one ID character string is assigned to one user. However, the present invention is not limited to this, and according to the present embodiment, one ID character string is assigned. The column can also be used to authenticate multiple users.

  For example, as shown in FIG. 10, one “department ID” is assigned and registered for each department (group), and a user belonging to the department is assigned a department ID assigned to the department to which the user belongs. Register your own input timing and input time. In this case, the character string of the department ID corresponds to identification information for identifying the group to which the user belongs, and input timing and input time correspond to identification information for identifying the user.

  In this way, by using a configuration in which one ID character string is assigned to each department, for example, usage information aggregation (for example, the number of printed sheets) of the MFP 2 can be performed in both department units (for each department ID) and individual units (for each input timing). Can be aggregated. Thus, according to the present embodiment, the number of issued IDs is reduced to facilitate the management of IDs and the association with shared information, and the association with personal information according to the input timing and input time is also possible. be able to.

  FIG. 11 is a flowchart for explaining a method of managing a processing history for each user.

  For example, in the authentication process for using the MFP 2, when the authentication process (S 401) in the authentication process unit 104 is successful (S 402, Yes), the authentication process unit 104 stores the identification information of the user who has succeeded in the authentication in the MEMORY 108 or the database 4. (S403).

  Subsequently, when the user selects a function to be used in the MFP 2 (S404), history information on the use of the selected function is stored in the MEMORY 108 or the database 4 (S405). Then, the history information is associated with the user identification information and stored in the MEMORY 108 or the like (S406). When another function is used again (S407, Yes), the process returns to the selection of the used function (S408). On the other hand, when the use of the function of the MFP 2 is completed (S407, No), the process ends.

  FIG. 12 is a flowchart for explaining a management method of the usage record using the department ID described above by the administrator.

  When the authentication system administrator succeeds in the authentication process (S501) by the authentication processing unit 104 (S502, Yes), the administrator proceeds to selection of an item to be confirmed (S503). Here, when it is desired to check the usage status for each department (S504, for each department), the usage status for each department is displayed on the display unit 109 (S505).

  On the other hand, when the administrator wants to check the usage status for each user (S504, for each individual), the usage status for each user that can be grasped by the administrator is displayed on the display unit 109 (S506). When the administrator confirms other information (S507, Yes), the process returns to the selection of the item to be confirmed (S508). On the other hand, when the confirmation of information is completed (S507, No), the process ends.

  As a specific example, when the MFP 2 is used and authentication processing by the authentication system according to the present embodiment is required, simple information such as the number of copies can be aggregated for each group. On the other hand, if you want to print a document containing personal information through the MFP, you can improve the security level for personal information by disabling printing even if the information is spooled but not authenticated. Can be made.

  In addition, as an application example described above, by performing authentication processing on the MFP 2 (directly or indirectly through another device) first, a list of information that can be printed by the user can be displayed and printed. On the contrary, it is possible to prevent access to information including personal information unless the authentication process is performed.

  As another application example, an ID character string is shared for each group, and an operation associated with information different for each user such as input time and input timing can be arbitrarily added by each member of the group. Good. At the stage when the group ID is first registered, the input timing of the members of the group is not registered. After that, when registering a certain operation method (such as a shortcut or communication with an address book partner), the input timing of an ID for using the method is also registered.

  In addition, if the MFP 2 has various functions according to the settings such as “print data stored inside” and “send scanned contents by e-mail”, set these settings. When the user of the group performs, the operation for using the setting is registered in association with the input timing of each user's ID, and the customization corresponding to each user can be performed.

  As described above, according to the present embodiment, the timing and rhythm of character input in the authentication process are not set as one of independent security check items, but as part of personal classification information corresponding to an ID. I handle it. Therefore, it can be used as a more secure authentication method. By incorporating the authentication function of the authentication system according to the present embodiment into a driver, application, or the like to form a software authentication on an existing device, it can be realized at a lower cost than hardware authentication.

  In addition, by teaching the timing that serves as the input reference when inputting the ID character string, it is possible to easily measure the timing when the user inputs information.

  In addition, according to the present embodiment, since a plurality of users can be authenticated with one ID character string, it is possible to cope with an increase in the number of users to be authenticated without increasing the number of IDs issued as much as possible. Can do. In addition, the security level can be maintained even if the number of digits of the ID character string is reduced, and the number of operation inputs by the user during the authentication process can be reduced.

  Although the present invention has been described in detail according to particular embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
