Description

  The present invention relates to an OS restart method, an OS restart apparatus, and a computer-executable program. More specifically, when restarting an OS, the waiting time of a user is shortened while ensuring security. The present invention relates to an OS restart method, an OS restart device, and a computer executable program.

  In an information processing apparatus such as a personal computer, software such as an OS or an application is often requested to be updated from the viewpoint of version upgrade or function expansion. When the software is updated, it is often necessary to restart the OS. For example, a Windows (registered trademark) OS is required to be restarted about once a month due to a Windows (registered trademark) update or the like. When restarting the OS, in an environment such as a company where password logon is necessary, the process stops until logon, and it is necessary to input the password, log on, and wait for the user profile to be loaded.

  In order to ensure the security of the computer, the user is required to enter various passwords such as a power-on password, supervisor password, and hard disk (HDD) password after the power is turned on by pressing the start button. The Normally, inputting these passwords each time is a cumbersome operation by the user, so a so-called single sign-on (SSO) method that substitutes one password is also employed.

  FIG. 11 is a diagram illustrating an example of timing when the OS is updated at the time of restart. In some cases, the user leaves after the start of OS update / restart and closes the time until the end of update / restart. After the update / restart process (Software Update, POST / BIOS, Main Path Boot Time) is performed, a logon screen is displayed. After returning to the seat, the user enters a password on the logon screen, and after the user profile is loaded, the OS performs normal operations. Here, there is a problem in that the user waits until the user profile is loaded after entering the password, and the user has to wait for the user who wants to use the personal computer quickly.

  As a method of shortening the waiting time, there are a method not using a login password and a method using SSO pre-boot authentication. The method that does not use the login password has a security problem. FIG. 12 is a timing chart for explaining a method of using SSO pre-boot authentication when updating the OS at the time of restart. In this figure, after Update / Restart processing (Software Update, POST / BIOS, Main Path Boot Time) is performed, SSO pre-boot authentication is performed, and after the user profile is loaded, the OS operates normally. I do. In this case, while the user is away, another person can use the personal computer, which is problematic in terms of security. As a method for using the resume function at the time of restart, for example, Patent Document 1 is known.

  As shown in FIG. 1, the OS restart device 1 according to the present invention includes an authentication information input module 2, an authentication module 3, an OS restart module 4, and a screen lock / release module 5. .

  The authentication information input module 2 is for inputting user authentication information. Here, the authentication information is, for example, biometric information (fingerprint, voiceprint, vein, palm shape, retina, iris, etc.), password, USB token, ID, etc., or a combination thereof. The authentication information input module 2 can be configured with a keyboard, a biometric information sensor, a USB memory, and the like.

  The authentication module 3 is for authenticating user authentication information input from the authentication information input module 2, and can be constituted by a hardware or software module, or a combination thereof. The OS restart module 4 is for restarting the OS, and can be realized by, for example, a partial function of the OS, a utility program, a BIOS, or the like. The restart of the OS is performed in the case of OS update, application update or installation, machine trouble, and the like. The screen lock / release module 5 performs screen lock and release of the screen 6, and can be realized by, for example, a partial function of the OS, a utility program, or the like.

  With reference to FIG. 2, an outline of the OS restart procedure of the OS restart device 1 will be described. In FIG. 2, the OS restart module 4 executes OS restart when an OS restart execution instruction is input. When the OS restart module 4 executes OS restart, the user inputs authentication information from the authentication information input module 2 before the shutdown (step S1). The authentication module 3 authenticates user authentication information input from the authentication information input module 2 (step S2). When the OS is restarted after the shutdown, the OS restart module 4 uses the authentication information authenticated before the shutdown from the authentication module 3 or the authentication information associated with the authenticated authentication information as the authentication information for OS logon. And authenticate the logon of the OS and load the user profile (step S3).

  The screen lock / release module 5 executes screen lock after the logon of the OS (step S4). After the screen lock, the user inputs authentication information from the authentication information input module 2 (step S5). The authentication module 3 authenticates the user authentication information input from the authentication information input module 2 (step S6). The screen lock / release module 5 acquires the authentication information authenticated after the screen lock from the authentication module 3 or the authentication information associated with the authenticated authentication information as the screen lock release authentication information, and releases the screen lock. The screen lock is released (step S7).

  According to the above configuration, when the OS is restarted, before the shutdown, the authentication module 3 authenticates the authentication information input from the authentication information input module 2 in response to the user operation, and restarts the OS. When the OS is started after the shutdown, the module 4 acquires the authentication information authenticated before the shutdown from the authentication module 3 or the authentication information associated with the authenticated authentication information as the OS logon authentication information. The screen lock / release module 5 executes screen lock after the OS is started, and the authentication module 3 responds to the user operation from the authentication information input module 2 after the screen is locked. The authentication information of the input user is authenticated, and the screen lock / release module 5 The authentication information authenticated after the screen lock from the screen 3 or the authentication information associated with the authenticated authentication information is acquired as the screen lock release authentication information, the screen lock release authentication is performed, and the screen lock is Since the release is performed, when the OS is restarted, it is possible to reduce the waiting time of the user while ensuring the security. In other words, it is possible to reduce the user restraint time when the OS is restarted, that is, the time during which the user cannot operate the PC or the like because the restart process is in progress but cannot leave the seat from the viewpoint of security.

  When screen lock is performed, authentication information authenticated before shutdown or information associated with the authenticated authentication information is acquired from the authentication module 3 as authentication information of an application that requires authentication at startup. You may authenticate and start the said application.

  The fingerprint reader 22 reads the user's fingerprint with a swipe fingerprint sensor and outputs it to the fingerprint authentication device 21. The fingerprint authentication device 21 is a single sign-on-chip that realizes single sign-on that enables authentication from boot to logon to the OS with one fingerprint authentication. The fingerprint authentication device 21 includes a non-volatile memory that stores the fingerprint 101A and a POP (power-on password), SVP (supervisor password), HDP (HDD password), and the like associated with the fingerprint 101. . Although the fingerprint authentication device 21 can register fingerprints of a plurality of users, in the following description, for the sake of simplicity of explanation, it is assumed that a fingerprint of one user is registered.

  FIG. 4 is a schematic diagram showing an outline of a functional configuration related to the restart of the OS of the computer system 10 of FIG. In FIG. 4, the fingerprint reader 22 reads the user's fingerprint and outputs the fingerprint 101 to the fingerprint authentication device 21. The user inputs a fingerprint (for example, swipes a finger) from the fingerprint reader 22 according to the fingerprint input request screen before the OS restart process is shut down and after the screen is locked. The fingerprint authentication device 21 associates the fingerprint 101A with the BIOS PW102A, logon ID / PW103A, screen unlock ID / PW104A, etc., and stores them in the nonvolatile memory.

  The fingerprint authentication device 21 compares the fingerprint 101 input from the fingerprint reader 22 with the stored fingerprint 101A, and authenticates the user when the two match. Since the algorithm for detecting the fingerprint match is well known, its detailed description is omitted. When the BIOS PW is requested from the BIOS 12a and the user authentication is successful, the fingerprint authentication device 21 outputs the stored BIOS PW 102A to the BIOS 12a. When the logon authentication / PW is requested from the OS 30 and the user authentication is successful, the fingerprint authentication device 21 outputs the stored logon ID / PW 103A to the OS 30. Further, the fingerprint authentication device 21 performs fingerprint authentication for canceling the screen lock, and when the user authentication is successful, outputs the stored screen lock / release ID / PW 104A to the OS 30.

  The BIOS 12a requests the BIOS PW from the fingerprint authentication apparatus 21, and performs authentication by checking the BIOS PW 102A input from the fingerprint authentication apparatus 21 in response to the request and the stored BIOS PW 102B.

  The OS 30 includes a restart processing unit 31 and a screen lock / release unit 32. The restart processing unit 31 is for performing processing for restarting the OS 30. When the OS 30 is restarted, the restart processing unit 31 displays a fingerprint input request screen on the LCD 16 before the shutdown. Further, the restart processing unit 31 requests the logon ID / PW from the fingerprint authentication device 21, and in response to the request, the logon ID / PW 103A input from the fingerprint authentication device 21 and the stored logon ID / PW 103C. If the two match, logon processing is performed.

  The screen lock / release unit 32 executes screen lock after the OS 30 is started in the restart process of the OS 30. The screen lock / release unit 32 displays a fingerprint input request screen on the LCD 16 for releasing the screen lock after the screen lock. The screen lock / release unit 32 executes screen lock after the OS 30 is activated, and displays a fingerprint input request screen on the LCD 16 after the screen lock.

  FIG. 5 is a flowchart for explaining an outline of the OS restart operation of the computer system 10 shown in FIG. FIG. 6 is a diagram illustrating a display example of the LCD 16 when the OS is restarted. With reference to FIG. 5 and FIG. 6, the operation when the OS is restarted automatically or in response to an operation instruction of HID 19 will be described.

  5, first, the restart processing unit 31 of the OS 30 starts a restart (see FIG. 6 (101)), and displays a fingerprint input request screen (see FIG. 6 (102)) on the LCD 16 (step U11). . When the user inputs the fingerprint 101 with the fingerprint reader 22 in accordance with the fingerprint input request screen (step S11), the fingerprint authentication device 21 determines whether or not the fingerprint 101 input from the fingerprint reader 22 matches the stored fingerprint 101A. Is determined (step S12). When the fingerprints match (“Yes” in step S12), the fingerprint authentication device 21 notifies the OS 30 of successful fingerprint authentication (step S14). When the fingerprints do not match (“No” in step S12), The OS 30 is notified of the fingerprint authentication failure (step S13). When the restart processing unit 31 receives the notification of the fingerprint authentication failure, the restart processing unit 31 displays that the fingerprints do not match on the fingerprint input request screen.

  Upon receiving the notification of the success of fingerprint authentication, the restart processing unit 31 starts shutdown (see FIG. 6 (103)) (step U12). When the shutdown is completed (step U13), the BIOS 12a is started (step T11). ). The BIOS 12a requests the BIOS PW from the fingerprint authentication device 21 (step T12). The fingerprint authentication device 21 sends out the BIOS PW102A associated with the fingerprint 101A to the BIOS 12a in response to the request (step S15).

  The BIOS 12a determines whether or not the BIOS PW102A input from the fingerprint authentication device 21 matches the stored BIOS PW102B. If they match, the BIOS 12a starts the boot loader of the restart processing unit 31 (Step S1). T13), the boot loader starts the OS startup process (see FIG. 6 (104)) (step U14). The BIOS 12a displays an authentication failure on the LCD 16 when the BIOS PW102A and the BIOS PW102B do not match.

  When the startup process of the OS 30 ends (step U15), the restart processing unit 31 requests the logon ID / PW from the fingerprint authentication device 21 (step U6). In response to the request, the fingerprint authentication device 21 sends the logon ID / PW 103A associated with the fingerprint 101A and a screen lock execution command to the OS 30.

  The restart processing unit 31 determines whether or not the logon ID / PW 103A input from the fingerprint authentication device 21 matches the stored logon ID / PW 103C. If they match, the user profile loading process is performed. (Refer to FIG. 6 (105)) (step U19), the screen lock / release unit 32 executes screen lock according to the screen lock execution command of the fingerprint authentication device 21, and after the screen lock, a fingerprint input request A screen (see FIG. 6 (106)) is displayed on the LCD 16 (step U18). If the logon ID / PW 103A does not match the stored logon ID / PW 103C, the restart processing unit 31 displays an authentication failure on the LCD 16.

  When the user inputs a fingerprint with the fingerprint reader 22 in accordance with the display of the fingerprint input request screen (step S17), the fingerprint authentication apparatus 21 matches the fingerprint 101A in which the fingerprint 101 input from the fingerprint reader 22 is stored. It is determined whether or not (step S18). If the fingerprints match (“Yes” in step S18), the fingerprint authentication device 21 sends the screen lock release ID / PW 104A associated with the fingerprint 101A to the screen lock / release unit 32.

  After the user profile loading process ends (step U19), the screen lock / release unit 32 matches the screen unlock ID / PW 104A input from the fingerprint authentication device 21 with the stored screen unlock ID / PW 104C. If they match, the screen lock is released (see FIG. 6 (107)) (step U20). As a result, the user can use the computer system 10. The screen lock / release unit 32 displays an authentication failure on the LCD 16 when the screen unlock ID / PW 104A input from the fingerprint authentication device 21 does not match the stored screen unlock ID / PW 104C. .

  FIG. 7 is a diagram illustrating an example of timing when the OS is updated at the time of restart in the present embodiment. The user can leave the desk after inputting the fingerprint at the start of the restart. After Update / Restart processing (Software Update, POST / BIOS, Main Path Boot Time) is performed, the user is automatically logged on with single sign-on, and the user profile is loaded and screen lock is executed. When the user returns to the seat and inputs a fingerprint, the screen lock is released and the computer system can be used. In the prior art (see FIG. 11), after the user returns to the seat and inputs the logon password, the user profile is loaded, and during that time, a waiting time occurs, whereas in the present embodiment, the user profile Since the computer system can be used after the screen lock is released, it is possible to significantly reduce the waiting time of the user when the OS is restarted.

  According to the first embodiment, when the OS is restarted, the fingerprint input request screen for prompting the user to input a fingerprint is displayed before shutdown and after the screen is locked. It is possible to ensure security and shorten the waiting time when the OS is restarted with a simple operation of simply inputting.

Here, a case will be described in which the application A requires user authentication at the time of activation.

  The fingerprint authentication device 21 further stores the fingerprint 101A in association with the ID / PW of the application A in the nonvolatile memory.

  In response to a request from the application activation unit 33, the fingerprint authentication device 21 outputs the ID / PW 105A of the application A associated with the authenticated fingerprint 101A to the application activation unit 33.

  The OS 30 further includes an application activation unit 33. The application activation unit 33 requests the fingerprint authentication apparatus 21 for the ID / PW of the application A, and the ID / PW 105A of the application A input from the fingerprint authentication apparatus 21 in response to the request and the ID / PW of the stored application A Checking with the PW 105C is performed, and if the two match, processing for starting the application A is performed. In addition, the application activation unit 33 has a resume function. When the OS 30 is restarted while the application A is being executed, the status information (interruption information) of the application A is stored in the HDD 14 or the like, and the OS 30 is restarted. Later, the state of the application A is restored (reproduced) according to the state information.

After inputting the fingerprint 101 and receiving the notification of successful fingerprint authentication (steps U11, S11, and S14), the application activation unit 33 of the OS 30 stores the status information of the fingerprint authentication application A (step U31). After saving the status information of the application A, shutdown is started (step U12).

  After completing the loading of the user profile (step U19), the application activation unit 33 requests the fingerprint authentication apparatus 21 for the ID / PW of the application A (step U32). The fingerprint authentication device 21 sends the ID / PW 105A of the application A associated with the fingerprint 101A to the application activation unit 33 (step S31).

  When the application A ID / PW 105A input from the fingerprint authentication device 21 matches the stored application A ID / PW 105A, the application activation unit 33 activates the application A and restores the state before the restart. (Step U32).

  When the screen lock is released by the user's fingerprint input (step U20), the application A can be used from the state before the restart (see FIG. 10 (202)).

  According to the second embodiment, the application starting unit 33 acquires the ID / PW of the application A from the fingerprint authentication device 21 and authenticates the screen when the OS 30 is restarted, and starts the application A. Therefore, it is possible to reduce the waiting time of the application activation user while ensuring security for the application that requires authentication at the time of activation.
