Description

  The present invention relates to an HDD driver that controls access to an HDD unit having a password lock function, and more particularly to an electronic apparatus such as a printing apparatus including the HDD driver.

  In recent years, not only personal computers (PCs) but also electronic devices such as printing apparatuses are increasingly equipped with hard disk drive units (hereinafter referred to as “HDD units”).

There are several standards for HDD units. Of these, the ATA (AT Attachment) standard restricts (locks) access to the HDD unit by setting a password (hereinafter referred to as “password lock function”). (Refer to Patent Document 1).
JP 2004-78539 A

  Conventionally, when a password is set in the HDD unit, the user once starts up the electronic device including the HDD unit in the BIOS function setting mode, inputs the password by using the password setting function of the BIOS, and then turns on the electronic device. It was necessary to restart.

  However, the work of restarting the electronic device after starting up in the BIOS function setting mode is complicated for the user, and it is considered that there are many users who do not know that the password can be set by the BIOS. Therefore, even if a high security level is required for the HDD unit, such as when highly confidential or property data is recorded, some users continue to use the HDD unit without setting a password. Not a few.

  Here, the invention described in Patent Document 1 employs a configuration in which the BIOS automatically generates a password using a random number table and sets it in the HDD unit.

  According to this configuration, there is no problem of continuing to use without setting a password. However, since the password is always set regardless of the user's intention, the user has high security in the HDD unit. If you don't need a level and think you don't need a password, you can't.

  On the other hand, in the invention described in Patent Document 1, since the generated password is held in the electronic device main body, it is not escaped from the risk of the password being leaked. In this respect, the user needs a high security level for the HDD unit. It can't be said that it is able to cope with the situation.

  Therefore, an object of the present invention is to provide a new technique that allows a user to reliably select a security level that is considered necessary for an HDD unit.

  The HDD driver of the present invention is an HDD driver for controlling access to an HDD unit having a password lock function, and the first type option for the user to determine the password with respect to the password setting, and the HDD driver Presents a menu screen configured to allow selection of a second type of option for determining a password, and a menu means for accepting a selection from the user, and when a first type of option is selected, a predetermined password is input When the password entered by the user via the screen is notified to the HDD unit and password lock setting means and the second type option are selected, the password is automatically created. The created password is notified to the HDD unit and the password is locked. Characterized in that it comprises a an auto password setting means for setting.

  According to this configuration, the user can appropriately select a password setting method for the HDD unit according to the security level that the user considers necessary for the HDD unit.

  Preferably, the menu means presents a menu screen configured to allow selection of a third type option using the HDD unit without setting a password. According to such a configuration, it is possible to appropriately cope with a case where the user thinks that setting of a password is unnecessary.

  Preferably, the menu means presents the menu screen and accepts a selection from the user on condition that the password lock function of the HDD unit is disabled when the electronic device in which the HDD driver is mounted is started up. It is characterized by that. According to such a configuration, it is possible to reliably avoid a situation in which the user continues to use the HDD unit without setting a password, unless the user intentionally does not set a password.

  Preferably, the menu means presents the menu screen and accepts a selection from the user when a third type option has not been selected in the past for the HDD unit. According to such a configuration, once the user has intentionally selected not to set a password, the user is not bothered by the task of selecting the security level every time the user starts up.

  Preferably, the menu means includes, as the second type of options, an option for automatically setting a password based on information unique to an electronic device in which the HDD driver is installed, and the HDD driver. A menu screen configured to be able to select an option for automatically setting a password based on information unique to the electronic device is presented. According to this configuration, in the second type in which the HDD driver automatically creates a password, it is possible to select password setting methods with different security levels corresponding to whether or not the HDD unit can be diverted.

  Also preferably, when the password created by the auto password processing means is notified to the HDD unit to release the password lock, and the password lock cannot be released by the password, the password is not displayed via a predetermined password input screen. It is characterized by comprising an adaptive lock release means for notifying the HDD unit of a password input by a user and trying to release the password lock. According to such a configuration, even when the security level of the password set in the HDD unit is not held in the electronic device in which the HDD driver is mounted, the password can be adaptively released. .

  The electronic device of the present invention includes the HDD driver of the present invention.

  An access control method according to the present invention is an access control method for an HDD unit having a password lock function. Regarding the password setting, a first type option for a user to determine a password, and the HDD driver sets a password. A menu screen configured to be able to select a second type option to be determined is presented, and when a selection is received from the user, and when the first type option is selected, via a predetermined password input screen When the manual password setting step for notifying the HDD unit of the password input by the user and setting the password lock and the second type option is selected, the password is automatically created, and the created password Autopass to notify the HDD unit and set password lock Characterized in that it comprises a chromatography de setting step.

  The access control method of the present invention can be implemented by an information processing unit (computer) included in an electronic device, and a program therefor is installed through various media such as a CD-ROM, a magnetic disk, a semiconductor memory, and a communication network. Or can be loaded. Further, when a printing apparatus is assumed as the electronic device, the case where the program is recorded and distributed on a printing apparatus card or a printing apparatus option board is also included.

  As described above, according to the present invention, it is possible to provide a new technique that enables a user to reliably select a security level considered necessary for an HDD unit.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a schematic configuration of a printer system according to the present embodiment. As shown in FIG. 1, the host device 10 is connected to the printer device 20 via a USB (Universal Serial Bus) interface. The printer device 20 is configured to be accessible to the HDD unit 30 via a predetermined interface. The standard of the predetermined interface is not limited to a specific standard as long as it supports a password lock function. However, the ATA standard will be described below as an example.

  In FIG. 1, the HDD unit 30 is described outside the printer device 20, but the printer device 20 may include the HDD unit 30 as a part thereof.

  The host device 10 includes hardware such as a CPU (processor), ROM, RAM, I / O controller, communication interface, USB host interface, and HDD. Functionally, a printer driver that controls the printer device 20, etc. It has.

  The printer driver is the same as a normal printer driver. In other words, when a print request specifying the printer device 20 is received from a user via an application program operating on the outside or the host device 10, a print job is created based on a predetermined printer control language that the printer device 20 can interpret. This is transmitted to the printer device 20 connected to the host device 10.

  A print job includes, for example, a job ID, output printer model information, a user name (user ID), a file name of a document to be printed, print setting information (number of copies, single-sided / double-sided printing, color / monochrome) Job information such as designation) can be included in the header.

  The printer device 20 has the same configuration as a normal printer device.

  For example, the printer device 20 includes a power supply mechanism that includes a paper feed mechanism that supplies paper into the printer device, a print engine that performs printing, and a paper discharge mechanism that discharges paper outside the printer. A print engine is usually configured to include a paper feed mechanism, a carriage mechanism, a print head, and the like. A serial printer that prints in units of characters, such as an inkjet printer or a thermal transfer printer, a line printer that prints in units of lines, and a page unit. Various print engines corresponding to a page printer or the like for printing can be used.

  In addition, for example, the printer device 20 includes a CPU, ROM, RAM (including nonvolatile RAM), a user interface such as a console panel, a USB device interface, an HDD unit connection interface (HDD host controller, connection connector, etc.) corresponding to the ATA standard. Including an information processing unit including hardware.

  The information processing unit of the printer device 20 has the same function as the information processing unit of the conventional printer device (see FIG. 2). For example, a USB driver 21 that controls communication with the host device 10 connected via the USB device interface, an HDD driver 22 that controls access to the HDD unit 30 connected via the HDD unit connection interface, and the host device 10 Raster format based on the print job and various data stored in the RAM or HDD unit 30, the reception control means 23 for receiving the print job, command, font data, form data, etc. transmitted from the RAM and the HDD unit 30 Based on the control command in the print job, the analysis / image generation means 24 generates one print image for one band or one page and stores it in the image buffer, and prints the print image for a predetermined unit (for example, one pass). Transfer from buffer to print engine , And a print control unit 25 or the like for executing printing by controlling the print engine.

  However, as shown in FIG. 2, the HDD driver 22 of the present embodiment includes a first type option that the user inputs and sets a password, in addition to the function of the conventional HDD driver, A menu screen configured so that the HDD driver can select a second type option for automatically setting a password is presented, and a security level selection menu function for accepting a selection from the user and a first type option selected If a manual password setting function for setting a password lock by notifying the HDD unit of a password input by a user via a predetermined password input screen and a second type option are selected, A password is automatically created, and the created password is notified to the HDD unit. In that it includes an automatic password setting function for setting the word lock, it is different from the conventional HDD driver.

  These means and drivers are functionally realized (implemented) when the CPU executes a program stored in a ROM or RAM in the printer device 20, an external storage medium, or the like.

  The HDD unit 30 includes hardware such as a connection interface, a controller, an HD, a drive mechanism, a ROM, and a RAM, and has various functions similar to those of a conventional HDD unit compliant with the ATA standard.

  The security level selection type password processing according to the present invention will be described below with reference to flowcharts defining the operation of the printer device 20 (HDD driver 22) shown in FIGS. In addition, each process (including the partial process to which the code | symbol is not provided) can be arbitrarily changed in order within the range which does not produce contradiction in the processing content, or can be performed in parallel. The HDD driver 22 has various functions, but a description of functions not directly related to the security level selection type password processing is omitted.

  When the printer device 20 is started up (when the power is turned on or reset), the HDD driver 22 executes the following security level selection type password processing as part of the initial processing.

  The HDD driver 22 checks the status of the HDD unit connection interface and determines whether or not the HDD unit is connected to the printer device 20 (S100).

  If it is determined that the HDD driver 22 is not connected, the HDD driver 22 ends the security level selection type password process.

  On the other hand, when determining that it is connected, the HDD driver 22 notifies the Identify Device command to the controller of the HDD unit 30 that is the connection destination (S101).

  The controller of the HDD unit 30 that has received the command refers to the ROM or non-volatile RAM, and the serial number of the HDD unit 30, information related to the password lock function (the presence or absence of the lock function, and the function is valid if there is a lock function) If the lock function is valid, the read-inhibited state or the readable state is read out, and the like is returned to the HDD driver 22 as Identify Device information.

  When the HDD driver 22 acquires the Identify Device information of the HDD unit 30, it determines whether or not the HDD unit 30 has a password lock function based on the information (S102).

  If it is determined that the HDD driver 22 does not have it, the HDD driver 22 ends the security level selection type password processing.

  On the other hand, if it is determined that the password lock function is provided, the HDD driver 22 determines whether the password lock function is valid or invalid based on the Identify Device information (S103).

  If it is determined that the password lock function is invalid, the HDD driver 22 uses the HDD unit without setting a password in the security level selection menu screen described later with respect to the HDD unit 30 (third type). It is determined whether or not the security level is selected (S104).

  Specifically, it can be determined as follows. As will be described later, when the third type of security level is selected in this process, the identification information (such as the serial number) of the HDD unit 30 is stored in a predetermined area of the nonvolatile RAM in S107. Therefore, the identification information of the HDD unit 30 currently connected is extracted from the acquired Identify Device information, and the identification information stored in the predetermined area of the nonvolatile RAM (that is, security level selection type password processing is executed in the past). And the identification information of the HDD unit for which the third type security level is selected at that time. At this time, if a plurality of pieces of identification information are stored, they are compared with each other. If there is matching identification information, it is determined that the security level selection type password processing has been executed in the past for the HDD unit 30 that is currently connected, and the third type security level has been selected at that time. .

  When it is determined that the third type of security level has been selected in the past for the HDD unit 30, the HDD driver 22 ends the security level selection type password process.

  On the other hand, if it is determined that the third type of security level has not been selected in the past for the HDD unit 30, the HDD driver 22 displays a security level selection menu screen on the console panel or the like (S105).

  The security level selection menu screen is configured such that the user can select a first type option that is set by inputting a password and a second type option that the HDD driver automatically sets a password.

  The second type of options are an option for automatically setting a password based on information unique to the printer device 20 (setting a non-reusable password), and a password being automatically set based on non-unique information for the printer device 20 Option (setting a divertable password) to be included.

  As information unique to the printer device 20, for example, a serial number of the device information of the printer device 20 can be used. Since the random numbers assigned to the printer device 20 are unlikely to overlap with each other, they can be used as information inherent to the printer device 20 substantially.

  In addition, as information that is not unique to the printer device 20, for example, a manufacturer name, a model name, or the like in the device information of the printer device 20 can be used. Since such device information is common between printer devices of the same manufacturer and the same model, a password created based on the device information is also common between printer devices of the same manufacturer and the same model, and as a result, the password Can be used (shared) between these printer apparatuses.

  Furthermore, the security level selection menu screen according to the present embodiment is configured such that a third type option using the HDD unit can be selected without setting a password.

  Next, the HDD driver 22 waits for an input from the user (S106). And if selection is received from a user via the said menu screen, it will transfer to the process corresponding to the choice which the user selected.

  When the third type option is selected, the HDD driver 22 extracts the identification information (such as a serial number) of the HDD unit 30 from the acquired Identify Device information and stores it in a predetermined area of the nonvolatile RAM ( S107), the security level selection type password processing is terminated.

  In the third type, since no password is set in the HDD unit 30, the security level based on the password is the lowest, but when the individual user uses the printer device 20 at home, the HDD unit 30 has a high security level. If it is considered unnecessary, selecting this third type can save time and effort related to password processing.

  When the first type option is selected, the HDD driver 22 displays a predetermined password input screen on the console panel or the like, acquires a password input by the user via the input screen (S108), and S111. Proceed to step.

  In the first type, information related to a password is stored in the printer device 20 although there is a trouble that the user has to input the password each time in password processing (setting, cancellation, invalidation, etc.). Since there is no need to avoid the risk of a password leaking from the apparatus body, a high security level can be secured.

  When the non-reusable password setting is selected from the second type options, the HDD driver 22 reads out unique information, for example, device information such as a serial number, by referring to the ROM, RAM, and the like of the printer device 20, Based on the unique information (hereinafter referred to as “password creation unique information”), a password for the HDD unit 30 is automatically created (S109), and the process proceeds to S111. Instead of reading out and using the serial number or the like, a random number may be generated and stored in the non-volatile RAM of the printer device 20 and used as the password creation unique information of the printer device 20.

  When the reusable password setting is selected from among the second type options, the HDD driver 22 refers to the ROM, RAM, etc. of the printer device 20 to provide non-unique information such as a manufacturer name, model name, etc. The information is read, and a password for the HDD unit 30 is automatically created based on the non-unique information (hereinafter referred to as “password creation non-unique information”) (S110).

  As a method for creating a password from the unique information for password creation and the non-unique information, for example, an anagram technique may be used. For example, when the non-unique information for password creation is model information “LP-8000C”, a password “P08C0-L0” can be created by replacing each character in a predetermined order. In addition to simply replacing the characters, for example, the character code of each character may be replaced with another character by changing to another character, or using various conventional encryption techniques other than the anagram method You may create a password. However, this password creation logic (in the case of the anagram method, the replacement order, etc.) is fixed, and therefore the same password is created every time.

  The second type can reduce the burden on the user because the user does not need to input the password each time in password processing (setting, cancellation, invalidation, etc.) while ensuring security by the password. It is considered that the security level is lower than the case where the user enters and sets the password in that there is a risk that the password creation unique information, non-unique information, and password creation logic will leak.

  Also, when creating a password that cannot be diverted, although the convenience is reduced in that the HDD unit 30 cannot be accessed from another printer device or the like, the security level is increased. On the other hand, when a reusable password is created, it can be diverted to other printer devices and the like, which is more convenient. However, as the number of devices that can access the HDD unit 30 increases, the security level is considered to be lower than that of non-reusable passwords.

  When the password creation unique information is a random number, the random number can be used as it is as a password.

  After acquiring or creating a password, the HDD driver 22 notifies the controller of the HDD unit 30 of the password together with a security set password command (S111).

  Upon receiving the security set password command, the controller of the HDD unit 30 stores the password received together with the command in a nonvolatile RAM or the like in the HDD unit 30 and enables the password lock function. When the password lock function is enabled, the access restriction status of the HDD unit 30 takes a read prohibition state as a default value when the power is turned on or reset. Next, the controller of the HDD unit 30 replies to the HDD driver 22 that a password has been set. On the other hand, if the password lock function could not be enabled for some reason, such as being unable to store the password (if the password could not be set), the controller of the HDD unit 30 maintains the password lock function disabled and the HDD A reply that the password could not be set is returned to the driver 22.

  When the HDD driver 22 receives a reply to the security set password command from the HDD unit 30, the HDD driver 22 determines whether or not a password can be set in the HDD unit 30 based on the reply content (S112).

  If it is determined that the password could not be set, the HDD driver 22 displays a message such as “Password could not be set” on the console panel or the like (S113), and ends the security level selection type password processing. When a password is created, the created password is discarded without being stored in the printer device 20 (for example, not stored in the nonvolatile RAM) upon completion of the security level selection type password process. (The same applies hereinafter).

  If it is determined that the password has been set, the security level selection type password processing is terminated.

  When the password is set, the access restriction status of the HDD unit 30 takes a read prohibition state as a default value at the next power-on or reset.

  On the other hand, if it is determined in S103 that the password lock function is valid, the HDD driver 22 executes adaptive lock release processing (S114 to S123).

  That is, the HDD driver 22 reads non-unique information for password creation from the ROM or the nonvolatile RAM, and automatically creates a first password candidate based on the information (S114).

  Along with the security unlock command, the created first password candidate is notified to the controller of the HDD unit 30 (S115), and an attempt is made to cancel the password lock.

  The controller of the HDD unit 30 that has received the security unlock command checks whether or not the password received together with the command matches the password stored in the nonvolatile RAM or the like in the HDD unit 30. When the passwords match, the controller of the HDD unit 30 changes the access restriction status of the HDD unit 30 from the read-inhibited state (default value at power-on or reset) to the readable state, and to the HDD driver 22 Reply that password lock is released. On the other hand, if the passwords do not match, the controller of the HDD unit 30 keeps the status of the HDD unit 30 in a read-inhibited state, and returns to the HDD driver 22 that the password lock could not be released.

  Upon receiving a reply to the security unlock command from the HDD unit 30, the HDD driver 22 determines whether or not the password lock of the HDD unit 30 has been released based on the reply content (S116).

  If the HDD driver 22 determines that the password has been canceled, the security level selection type password processing ends.

  On the other hand, if it is determined that the password could not be canceled, the HDD driver 22 reads the password creation specific information from the ROM or the nonvolatile RAM, and automatically creates a second password candidate based on this (S117).

  Then, together with the security unlock command, the created second password candidate is notified to the controller of the HDD unit 30 (S118) to attempt to unlock the password.

  When the HDD driver 22 receives a reply to the security unlock command from the HDD unit 30 operating in the same manner as described above, it determines whether the password lock of the HDD unit 30 has been released based on the reply content (S119).

  If the HDD driver 22 determines that the password has been canceled, the security level selection type password processing ends.

  On the other hand, if it is determined that the password could not be canceled, the HDD driver 22 displays a predetermined password input screen on the console panel or the like, and acquires the password input by the user via the input screen (S120).

  Then, along with the security unlock command, the acquired password is notified to the controller of the HDD unit 30 (S121), and an attempt is made to release the password lock.

  When the HDD driver 22 receives a reply to the security unlock command from the HDD unit 30 from the HDD unit 30 operating in the same manner as described above, it determines whether the password lock of the HDD unit 30 has been released based on the reply content (S122). ).

  If the HDD driver 22 determines that the password has been canceled, the security level selection type password processing ends.

  On the other hand, if it is determined that the password could not be canceled, the HDD driver 22 displays a message such as “The HDD cannot be used because the passwords do not match” on the console panel (S123), and the security level selection type password processing is terminated. In addition, when it cannot cancel | release, you may comprise so that the process of S120-S122 may be repeated to predetermined times (for example, 3 times).

  As described above, the HDD driver 22 according to the present embodiment can select the first type of option for the user to determine the password and the second type of option for the HDD driver 22 to determine the password. When the configured security level selection menu screen is presented and the user selects the first type option, the password entered by the user via the predetermined password input screen is notified to the HDD unit 30 and the password lock is performed. When the setting is made and the user selects the second type of option, the password is automatically created, and the created password is notified to the HDD unit 30 to set the password lock. Depending on the security level that the user considers necessary for the HDD unit, Password method of setting the knit 30 can be appropriately selected.

  The HDD driver 22 is configured to present a security level selection menu screen on condition that the password lock function of the HDD unit 30 is disabled when the printer device 20 is started up. Except for the case where no password is set, it is possible to reliably avoid the situation where the HDD unit 30 continues to be used without setting a password. On the other hand, when the third type of security level has been selected in the past for the HDD unit 30, the security level selection menu screen is not presented, and therefore when the user has intentionally selected not to set a password once. The user is not bothered by the operation of selecting the security level when starting up the printer device 20.

  Further, when the password lock function of the HDD unit 30 is valid, that is, when a password is set, the HDD driver 22 first uses password candidates that can be automatically created based on the password creation unique information and non-unique information. In this case, the password is set to the HDD unit 30 and the security level of the password set in the HDD unit 30 is set in the printer device 20. Even when the password is not held in the password (for example, when a password is set in the HDD unit 30 by another device), the password can be canceled adaptively.

(Modification)
The present invention is not limited to the above-described embodiment, and can be variously modified and applied. For example, the host device 10 and the printer device 20 may be connected based on a standard (protocol) other than USB.

  In the above-described embodiment, the printer apparatus is described as an example of the electronic apparatus. However, the present invention can also be applied to an electronic apparatus such as a copying machine, a facsimile machine, and a multifunction machine.

  Further, a part or all of the HDD driver 22 may be realized by hardware, or may be realized as a function of an OS or BIOS mounted on an electronic device.

  In the above embodiment, the password candidate based on the non-unique information for password creation is tried first, and then the password candidate based on the unique information for password creation is tried first. Processing may be configured in reverse order.

  Further, in the above embodiment, when the password lock of the HDD unit 30 cannot be released even by the password input by the user in the adaptive lock release process, a predetermined message is output and the process is terminated. In such a case, an error message may be output and the process may be stopped as is (does not proceed to the next process).

  In the above embodiment, the password lock of the HDD unit 30 is released by the adaptive lock release process. However, the security level selected by the user when setting the password is stored in the nonvolatile RAM of the printer device 20. A configuration may be adopted in which the password corresponding to the stored security level is acquired and the password lock of the HDD unit 30 is released when the lock is released.

  In the above-described embodiment, the HDD unit for which the user has selected the third type of security level is configured so that the security level selection menu screen is not displayed after the selection. The security level may be reselected. Or, for example, when the user instructs “setting initialization”, the security unit selection menu screen is displayed when the HDD unit identification information stored so far is deleted and the printer device 20 is started up next time. You may comprise. However, if the password has already been set and used, in order to display the security level selection menu screen and change the security level, it is necessary to disable the password lock function once using the already set password. is there.
