When the user inputs the identification information and password information from input means 40, receiving means receives the identification information and the password information, based on the identification information and the password information, reading means reads authority information corresponding to the password information from an authentication information table 60, and output means outputs the identification information and the read authority information to the operating system (OS) 20.

Description

  The present invention relates to an authentication method in the case of performing user authentication processing at the time of login processing to a system such as a computer.

  Conventionally, when a user logs in to an operating system or application system of a computer, the following processing is performed.

  A pair of identification information and password information is managed in advance for each user, and the user inputs the identification information and the password information, and performs personal authentication by matching or mismatching of the information.

  When the user authentication is performed, the authority is given based on the authority information set in advance corresponding to the identification information input and designated.

  The authority includes the authority to manage the operating system or application system of the computer, the administrator authority that can access all resources, and the limited user authority that cannot access some resources of the operating system or application program. There is. A resource means application software, a hardware device, or the like that configures and operates a computer system. For example, an external storage device connected to a computer, a printer, an application program, data, and the like.

  FIG. 4 shows states of administrator authority and restricted user authority.

  In FIG. 4, the administrator authority can read or write access to resource 1, resource 2, and resource 3, whereas the limited user authority allows read or write access to resource 1. This indicates that the read-only access to the resource 2 is possible and the read-write access to the resource 3 is impossible.

  In addition, there are operating systems in which the authority is not divided into two kinds of authority, that is, administrator authority and limited user authority, but is divided into more kinds of authority.

  The advantage of using the restricted user authority is that the important file operating on the operating system cannot be deleted with the restricted user authority, so that the safety of the entire system is improved. Therefore, it is desirable to use a limited operating authority for daily use of the operating system. On the other hand, when a new device is added to a computer device or when an application program is newly added, processing with administrator authority may be required to perform settings for operating them. Some application software requires administrator authority depending on the application to be operated. Therefore, in such a case, it is necessary to log in and use with administrator authority. From the above, it is desirable to use the operating system by properly using both authorities.

  In addition, there is a type in which authority is determined by adding management information to each identification information and managing the identification information (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2004-62241

  Conventional operating systems and application systems employ a configuration in which authority information is assigned for each piece of identification information. Therefore, even if the user is the same person, separate identification information is given for each authority. Furthermore, the user has to set environment information separately for the identification information for each authority.

  Here, the environmental information is information that is used for an operating system or application system, such as information for connecting to a network, information such as screen layout, application program usage information, hardware usage information, etc. Information about the environment.

  As described above, the user needs to repeatedly perform the same setting for each identification information, which requires a lot of time and labor. Furthermore, this operation is necessary every time new identification information is set, which is very burdensome for the user.

  The present invention functions as receiving means for receiving identification information and password information, reading means for reading out authority information corresponding to the password information from the identification information and password information, and output means for outputting the identification information and the authority information. It is characterized by that.

  The receiving means further includes means for receiving authority information, and the reading means reads the authority information when the identification information, password information, and authority information match the previously stored identification information, password information, and authority information. It is made to function as a means.

  Further, the password information is biometric information. Further, the password information is any one of fingerprint, palm print, iris, retina, blood vessel, vein pattern, handwriting, and voice print.

  With the configuration of the present invention, even if the identification information is the same, if the password and authority are different, it is possible to log in with a plurality of different authorities with the same identification information, and environmental information is recreated for each authority. There is no need.

  In addition, the user may select whether you want to log in with any authority in advance, in order to enter the password that corresponds to its authority, by entering the password for different authority, that the user be logged in with authority other than the desired privileges Disappears.

  Furthermore, password information for logging in can be logged in with different authorities depending on fingerprints, palm prints, irises, retinas, blood vessels, vein patterns, handwriting, voice prints, and the like.

FIG. 1 shows a system configuration diagram.

  The computer apparatus 10 includes an operating system (hereinafter referred to as OS) 20 and an authentication authority management program 30.

  The OS 20 provides basic functions used by other application software such as information input / output to / from the computer and management of connected devices, and is a program that functions to manage the entire computer system. is there.

  The authentication authority management program 30 is a program that causes a computer to function as a reception unit, a collation unit, an authority acquisition unit, and a transmission unit, and functions when a user logs in to the OS.

  The receiving means is means for receiving the identification information and password information received from the input means 40 via the OS 20, and the collating means is means for comparing the identification information and password information with information stored in the authentication information table 60. The acquisition unit is a unit that extracts authority information based on the collation result of the collation unit, and the transmission unit is a unit that transmits identification information and authority information to the OS 20.

  The input unit 40 is connected to the computer apparatus 10 and is a unit that receives input of identification information, password information, and the like from the user.

  The output means 50 is connected to the computer apparatus 10 and is a means for displaying a processing result performed by the computer apparatus 10 to the user. The authentication authority management program 30 described later outputs the identification information and authority information to the OS 20 instead of the output means 50.

  The authentication information table 60 is a data table that stores user information when performing authentication processing. FIG. 2 shows a data configuration example of the authentication information table 60. The authentication information table 60 includes user identification information 61, a password 62, and authority information 63. The identification information is information given to each user. In this figure, “MYID01”, “MYID11”,. . . It is. The password 62 is information given for each authority of the user, and is “PWD01” and “PWD02” with respect to “MYID01” in the figure. The authority 63 is information given in correspondence with the password 62, and in this figure, “PWD01” corresponds to “administrator” and “PWD02” corresponds to “restricted user”.

  In the case where the OS 20 has a plurality of levels of authority of 3 or more, it is possible to cope with the problem by increasing the items of the password 62 and the authority 63.

  FIG. 8 shows an example of the data structure of the authentication information table 60 when biometric information is used as a password. In the password 62 item in the figure, the left palm corresponds to the administrator authority, and the right palm corresponds to the restricted user authority. Thus, by assigning hands, fingers, eyes, etc. according to the authority, it is possible to log in easily.

  Here, as an example of hardware constituting the computer device 10 and the authentication information table 60 in the system configuration of the present invention, a CPU, a ROM, a RAM, an HDD (hard disk drive), and an HD (hard disk) , An FDD (flexible disk drive), and an FD (flexible disk) as an example of a removable recording medium. Each component is connected by a bus. The CPU controls the entire computer device 10. The ROM stores a program such as a boot program. The RAM is used as a work area for the CPU. The HDD controls reading / writing of data with respect to the HD according to the control of the CPU. The HD stores data written under the control of the HDD. The FDD controls reading / writing of data with respect to the FD according to the control of the CPU. The FD stores data written under the control of the FDD, or causes the information processing apparatus to read data recorded on the FD. As a removable recording medium, in addition to the FD, a CD-ROM (CD-R, CD-RW), MO, DVD (Digital Versatile Disk), memory card, or the like may be used.

  In addition, as an example of hardware constituting the output means 50 in the system configuration of the present invention, a window (browser) relating to data such as a document, an image, and function information is displayed as a display, such as a cursor, an icon or a tool box. indicate. For example, CRT, TFT liquid crystal display, plasma display and the like.

  The functions are realized by the CPU executing the OS 20, the authentication authority management program 30 and the like stored in the ROM, RAM, HD, FD, and the like. In addition, various data stored in the authentication information table 60 and a part of the data table may be generated and deleted as needed in a RAM used for work area purposes.

  In addition, as an example of hardware configuring the input unit 40 in the system configuration of the present invention, the keyboard includes keys for inputting characters, numbers, various instructions, and the like, and inputs data. It may be a touch panel type input pad. The mouse moves the cursor, selects a range, or moves and changes the size of the window. A trackball, a joystick, or the like may be used as long as it has a similar function as a pointing device.

  Furthermore, an apparatus for biometric authentication that recognizes fingerprints, palm prints, irises, retinas, blood vessels, vein patterns, handwriting, voiceprints and the like to enable biometric authentication is also included.

  FIG. 3 shows a flowchart of the authentication process. This flowchart describes a process in which the authentication authority management program 30 functions to allow the computer to send information for logging in to the OS after receiving information necessary for logging in from the user. It is.

  First, based on the login screen displayed on the output unit 50, the user inputs the user identification information and password by the input unit 40.

  FIG. 5 shows an example of a login screen displayed on the output unit 50.

  In the screen of FIG. 5, “ID:” is displayed as identification information and “Pass:” is displayed as password information, and there are input items in the right column of each.

  The user uses the input means 40 to input identification information and a password in the input items, and then presses a button on the “OK” screen. In this case, for example, it is assumed that the button on the screen is pressed by clicking with the mouse.

  The identification information and password input by the input means 40 are received by the computer device 10 and received by the OS 20, and the receiving means that is a function of the authentication authority management program 30 receives the identification information and password information from the OS 20 (S101). ).

  The verification unit that causes the computer to function by the authentication authority management program 30 searches whether the identification information received in S101 exists in the identification information 61 of the authentication information table 60 (S102).

  When the corresponding identification information 61 does not exist in the authentication information table 60 (S103: No), login failure information is transmitted to the OS 20 as login failure (S107).

  On the other hand, when the corresponding identification information 61 exists in the authentication information table 60 (S103: Yes), the password 62 in the record corresponding to the identification information 61 in the authentication information table 60 is searched (S104).

  If the password 62 does not exist in the record corresponding to the identification information 61 in the authentication information table 60 (S105: No), the login failure information is transmitted to the OS 20 as a login failure (S107).

  On the other hand, when the password 62 exists in the record corresponding to the identification information 61 of the authentication information table 60 (S105: Yes), the authority information 63 corresponding to the matching password 62 is read, and the identification information 61 and the login success information are displayed. In addition, it is transmitted to the OS 20 (S106).

  When the OS 20 receives the identification information 61 and the authority information 63 from the transmission unit, the OS 20 sets an environment corresponding to the user based on the identification information 61, and sets a resource access restriction based on the authority information 63.

(Example 2)
Next, processing when selecting and inputting authority information when inputting login information will be described.

  In this embodiment, since the user selects and inputs authority information in advance, if the authority that the user wants to log in differs from the authority corresponding to the password that was actually entered, the login information is output because the authority information is different. As a result, it is possible to eliminate the state in which the user logs in with an authority different from the authority desired and continues to use without noticing.

  FIG. 6 shows a flowchart (2) of the authentication process. This flowchart describes the processing from when the authentication authority management program 30 receives information necessary for logging in to the computer from the user until the information for logging in the user is transmitted to the OS. . In addition, the same code | symbol is attached | subjected about the step which performs the process similar to the flowchart of FIG. 3, and description is abbreviate | omitted.

  FIG. 7 shows a login screen example (2) displayed on the output means 50.

  In the screen of FIG. 7, “ID:” is displayed as identification information, “Pass:” is displayed as password information, and “authority:” to be logged in are displayed. The authority may be selected based on a preset authority type.

  The user uses the input means 40 to input identification information, password, and authority to log in to the input items, and presses a button on the “OK” screen. In this case, for example, it is assumed that the button on the screen is pressed by clicking with the mouse.

  The identification information and password input by the input unit 40 are received by the computer apparatus 10 and received by the OS 20, and the reception unit that is a function of the authentication authority management program 30 receives the identification information, password information, and authority information from the OS 20. (S201). Thereafter, the same processing as in FIG. 3 is performed. However, when the corresponding password 62 exists in the record corresponding to the identification information 61 of the authentication information table 60 (S105: Yes), the authority information 63 corresponding to the corresponding password 62 record is displayed. It is determined whether or not the input authority information matches (S206).

If the authority information 63 does not match (S206: No), login failure information is transmitted to the OS 20 as login failure (S107).

  On the other hand, when the authority information 63 matches (S206: Yes), the authority information 63 corresponding to the matching password 62 is read, and the identification information 61 and the login success information are combined and transmitted to the OS 20 (S106). Thereafter, the same processing as in the first embodiment is performed.

  As described above, the authority corresponding to the password is assigned by the identification information and the password information to which the authority determination at the time of login is input. Accordingly, various environments in the OS corresponding to the identification information 61 are called, and access restrictions on resources are applied based on the authority information 63.

  According to the present invention, the user can set up his / her environment only once, and can succeed to the environment even when other authority is acquired at a later date.

  In the present embodiment, the embodiment regarding the OS has been described. However, the present invention is applicable not only to the OS but also to an application system.

In this embodiment, since the case where the OS 20 and the authentication authority management program 30 are clearly separated is described, the information flow is described as being received from the OS 20 and transmitted to the OS 20. When it is incorporated in a part, it is an internal process.
