Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus and, more particularly, to an information processing apparatus which restricts an operator by a password and has improved measures for forgetting a password.

[0002]

2. Description of the Related Art In a conventional information processing apparatus, when the operator of the information processing apparatus is limited by a password, a password set by a person who is allowed to operate and known only to this person (hereinafter, An operator password) is stored in the information processing device, and a password entered by the operator from a keyboard or the like (hereinafter referred to as an input password) is collated with the operator password. When the two match, the operation is permitted. Is given to the operator. As a result, it is possible to prevent a person who does not know the operator password from illegally operating the information processing apparatus. However, if a person who is allowed to operate forgets the operator password, the information processing apparatus cannot be operated. In particular, privileged level operator passwords that allow unlimited access to all information are used infrequently and are therefore often forgotten by operators.

As a password forgetting measure, a special password (hereinafter referred to as a special password) is stored in the information processing apparatus in addition to the operator password, and the password stored in the floppy disk (hereinafter referred to as external password) is stored. Japanese Patent Laid-Open No. 4-361342 discloses a method of not executing a normal operator password collation on condition that the password is called) and the special password match. In this method, a special password is stored in the floppy disk as an external password, and when the password is forgotten, the operator mounts this floppy disk in the information processing apparatus. As shown in FIG. 12, when the information processing apparatus detects attachment of a floppy disk in step 1200, it reads the external password from the floppy disk in step 1201. Next, in step 1202, the external password read from the floppy disk is compared with the special password stored in the information processing apparatus. If the collations match, the process moves to step 1206, and the operation permission is given to the operator without requesting the password. Thus, the operator can operate the information processing device even if he forgets the operator password.

As another password forgetting method, a method of using an external password stored in a floppy disk instead of the input password input by the operator is disclosed in Japanese Patent Laid-Open No. 4-169959. In this method, the operator password is stored on the floppy disk as an external password. If the operator password is forgotten, the operator inputs the floppy disk set request key and mounts the floppy disk storing the operator password as an external password. As shown in FIG. 11, when the floppy disk mounting request key is input instead of the password input by the operator in step 1100, steps 1101 to 110
Move to 2. In step 1102, the external password is read from the floppy disk. Next, step 110
The external password read from the floppy disk in step 3 is collated with the operator password as the input password input by the operator. If the collations match, step 1
Operation permission is given at 104. This allows the information processing apparatus to be operated even if the password is forgotten.

However, as a problem common to these password forgetting measures, since the actual work can be started after the operation permission is obtained by these methods, the forgotten operator password remains set. However, there is a problem in that when the user tries to obtain the operation permission next time, these password forgetting measures must be used again.

As a solution to such a problem, the password is stored in the password management device (information processing device) on condition that the external password stored in the floppy disk and the input password input by the operator are matched. A password management device that enables the operation of the management device by erasing the operator password and prevents the forgotten operator password from being set remains It is disclosed in Japanese Patent No. 124266. Further, in this password management device, the operator password stored in the password management device as well as the external password stored in the floppy disk are erased, so that the floppy disk cannot be used and security is protected. We are trying to increase the effectiveness in terms of aspects.

[0007]

However, in the password management device, the operator may forget to reset the operator password after erasing the operator password.
In such a case, there is a problem that the operator password is not set in the password management device, and a third party can freely operate the password management device.

Further, in the password forgetting method in which the normal operator password collation is not performed by collating the external password stored in the floppy disk with the special password, the same special password is set for each information processing device. In this case, if you obtain this floppy disk, you will be able to obtain operation permission for all information processing devices. There was a problem that a high degree of care must be taken for storage. On the other hand, if different special passwords are set for each information processing device, separate floppy disks must be created for each information processing device in the manufacture of the floppy disk storing the special password as an external password. In addition, there is a problem in that the management of the created floppy disk requires a complicated work of associating each information processing device with the floppy disk.

The present invention has been made in order to solve such a problem. When a password is forgotten, the password is updated when the operation of the information processing apparatus is permitted, and the password is forgotten to be reset. It is an object of the present invention to provide an information management device that can prevent such a situation.

It is another object of the present invention to provide an information processing device capable of preventing unauthorized use by a third party when permitting operation of the information processing device when the password is forgotten.

Further, each of the information processors corresponds to
An object of the present invention is to provide an information processing device in which it is easy to create and manage a portable storage means that stores a special password.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. The first embodiment of the present invention corresponds to claim 1. 1 is a block diagram showing a hardware configuration of an information processing apparatus according to the first embodiment. In FIG. 1, reference numeral 12 is an information processing apparatus main body including a computer, and 11 is a password from the information processing apparatus main body 12 to an operator. It is an output device for transmitting information such as an input instruction, and for example, a display, a speaker for voice instruction, or the like can be used. Reference numeral 13 is an input device as an input means for inputting information such as a password from the operator to the information processing device main body 11, and for example, a keyboard or the like can be used. Reference numeral 14 is an operator password storage means for storing password information including a special password and a password storage device as a special password storage means, and for example, a hard disk drive, a battery backup memory or the like can be used.
Reference numeral 16 is a floppy disk as a portable storage means for storing an external password, and 15 is a floppy disk 16
Is a floppy disk drive as a mounting means for accessing the external password in the floppy disk 16, and these constitute the hardware of the information processing apparatus.

In the first embodiment, the operator password is stored in the floppy disk 16 as an external password. Further, the information processing apparatus main body 12 implements a discriminating means for discriminating whether or not the portable storage means is mounted, an input password collating means, an external password collating means, an operation permitting means, and an operator password updating means. Further, the operator password update requesting means is realized by the output device 11 and the information processing device main body 12.

FIG. 2 is a flow chart showing the operation permission processing of the information processing apparatus main body 12. The operation of the information processing apparatus according to the first embodiment will be described below with reference to FIGS. 1 and 2. When the operator normally tries to obtain the operation permission,
Since the operator remembers the operator password, the floppy disk 16 is not loaded in the floppy disk drive 15. The information processing apparatus main body 12 determines in step 200 whether or not the floppy disk 16 is present. Since the floppy disk 16 is not loaded, the process proceeds to step 201. When the existence of the operator password is confirmed in step 201, the process proceeds to step 202. In step 202, the operator is requested to input the password through the output device 11, and in response to this, the operator inputs the password through the input device 13. This input password is used as the information processing device body 1
2 is received in step 203. Next, step 204
Then, the input password entered by the operator is compared with the operator password stored in the password storage device 14, and if they match each other, an operation permission is given to the operator in step 205.

If the operator forgets the operator password,
Since the correct password cannot be input in response to the password input request in step 202, the input password in step 204 and the operator password do not match, the process cannot proceed to step 205, and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 200 whether or not the floppy disk 16 is present, and the floppy disk 1
Since No. 6 is attached, the process proceeds from step 200 to step 206. Next, in step 206, the information processing apparatus main body 12 reads the external password from the floppy disk 16 by the floppy disk drive 15.
Next, in step 207, the external password read in step 206 is compared with the operator password stored in the password storage device 14.

When the operator password is stored in the floppy disk 16 as the external password, the information processing apparatus main body 12 verifies the external password and the operator password in step 207 and the step 20 is executed.
Move to 8. In step 208, the information processing device main body 12 requests the operator to input a new password through the output device 11, and in response to this, the operator inputs the new password through the input device 13. Next, in step 209, the information processing apparatus main body 12 receives this new operator password. Next, in step 210, the information processing apparatus main body 12 updates the operator password in the password storage device 14 with the new operator password received in step 209. After that, the process moves to step 205 and the operation permission is given. Here, the operation permission may not be given. When the operation permission is not given, the operator can obtain the operation permission in steps 202 to 205 by inputting the updated operator password. This prevents the operator from forgetting to set a new password, and in the information processing device that gives the operator operation permission on the condition that the matching with the operator password is performed, after the operation permission is given to the operator, It is possible to prevent the forgotten operator password from being set, and the operator forgets to reset the operator password, such as when deleting the operator password, and the information processing device is It is possible to prevent freely operable.

On the other hand, when the external password is not stored in the floppy disk 16 or when an incorrect operator password is stored, the collation between the external password and the operator password in step 207 does not match. Then, the process proceeds to step 201. Step 2
In 01, the information processing apparatus main body 12 checks whether or not the operator password exists, and the operator password is set, so the process proceeds to step 202. Then, in step 202, a normal operator's password input is requested, but the operator cannot obtain the operation permission because he does not know the password. Therefore, a person who does not have a floppy disk in which the correct operator password is stored as an external password and who does not know the operator password can delete the operator password or obtain operation permission. First, it is prevented that such a person illegally deletes the operator password or obtains the operation permission.

Embodiment 2 The second embodiment of the present invention corresponds to claim 2. The hardware configuration of the information processing apparatus according to the second embodiment is the same as that of the first embodiment.

Since No. 6 is attached, the process proceeds from step 300 to step 306. In step 306, the information processing device main body 1
2 reads the external password from the floppy disk 16 by the floppy disk drive 15. next,
In step 307, the external password read in step 306 is compared with the special password stored in the password storage device 14.

When the special password is stored in the floppy disk 16 as the external password, the collation between the external password and the special password in step 307 coincides, and the process proceeds to step 308. In step 308, the information processing apparatus main body 12 issues a new password input request to the operator through the output device 11, and in response to this, the operator inputs the new password through the input device 13. Next, in step 309, the information processing apparatus main body 12 receives this new operator password. Next, in step 310, the information processing device main body 12 sends the password storage device 14
The operator password therein is updated to the new operator password received in step 309. Then step 3
Move to 05 and give operation permission. Note that this operation permission does not necessarily have to be given, as described in the first embodiment. As a result, in the information processing device that gives the operator permission to operate on the condition that the collation with the special password is the same, the operator password that has been forgotten and the operator password that has been forgotten remains set. In addition to the prevention of the operator password, it is possible to prevent the operator from forgetting to reset the operator password and allowing the information processing apparatus to be freely operated by a third party.

If the external password does not exist in the floppy disk 16 or if a different special password is stored as the external password, the collation between the external password and the special password in step 307 does not match, and step 301 is executed. Move. Step 30
In step 1, the information processing apparatus main body 12 checks whether or not an operator password exists, and since the operator password is set, the process proceeds to step 302. Then, in step 302, a normal operator's password input is requested, but since the operator does not know the password, the operation permission cannot be obtained. Therefore, do not have a floppy disk with the correct special password stored as an external password,

The operation of the information processing apparatus according to the third embodiment will be described below with reference to FIGS. 1 and 4. The case where the operator normally tries to obtain the operation permission is the same as that in the first embodiment, and therefore the description thereof is omitted.

If the operator forgets the operator password,
Since the correct password cannot be input in response to the password input request in step 402, the input password in step 404 and the operator password do not match, the process cannot proceed to step 405, and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 400 whether or not the floppy disk 16 is present, and the floppy disk 1
Since No. 6 is attached, the process moves from step 400 to step 406. Next, at step 406, the information processing apparatus main body 12 reads the external password from the floppy disk 16 by the floppy disk drive 15. Next, in step 407, the external password read in step 406 is compared with the operator password stored in the password storage device 14.

This will prevent the operator from forgetting to set a new password, and at the same time as updating the operator password, a floppy disk for storing the updated operator password will be obtained.
Even if you forget the updated operator password, it is possible to take corrective measures.

The case where the external password is not stored in the floppy disk 16 or the incorrect operator password is stored in the floppy disk 16 is the same as in the first embodiment, and the description thereof is omitted.

Fourth Embodiment The fourth embodiment of the present invention corresponds to claim 5. The hardware configuration of the information processing apparatus according to the fourth embodiment is the same as that of the first embodiment. In FIG. 1, in the second embodiment, a special password is stored in the floppy disk 16 as an external password. Further, the discriminating means for discriminating whether or not the portable storage means is mounted, the input password collating means, the external password collating means, the operation permitting means, and the operator password updating means are realized by the information processing apparatus main body 12. .

FIG. 5 is a flow chart showing the operation permission processing of the information processing apparatus main body 12. The operation of the information processing apparatus according to the fourth embodiment will be described below with reference to FIGS. 1 and 5. The case where the operator normally tries to obtain the operation permission is the same as that in the first embodiment, and therefore the description thereof is omitted.

If the operator forgets the operator password,
Since the correct password cannot be input in response to the password input request in step 502, the input password and the operator password in step 504 do not match each other, and the process cannot proceed to step 505 and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 500 whether or not the floppy disk 16 is present, and the floppy disk 1
Since No. 6 is attached, the process moves from step 500 to step 506. In step 506, the information processing device body 1
2 reads the external password from the floppy disk 16 by the floppy disk drive 15. next,
In step 507, the external password read in step 506 is compared with the special password stored in the password storage device 14.

Further, the operator password update requesting means is realized by the output device 11 and the information processing apparatus main body 12, and the external password updating means is realized by the information processing apparatus main body 12 and the floppy disk drive 15.

FIG. 6 is a flow chart showing the operation permission processing of the information processing apparatus main body 12. The operation of the information processing apparatus according to the fifth embodiment will be described below with reference to FIGS. 1 and 6. The case where the operator normally tries to obtain the operation permission is the same as that in the first embodiment, and therefore the description thereof is omitted.

If the operator forgets the operator password,
Since a correct password cannot be input in response to the password input request in step 602, the input password and the operator password in step 604 do not match, and it is impossible to move to step 605 and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 600 whether or not the floppy disk 16 is present, and the floppy disk 1
Since No. 6 is attached, the process proceeds from step 600 to step 606. In step 606, the information processing device body 1
2 reads the external password from the floppy disk 16 by the floppy disk drive 15. next,
In step 607, the external password read in step 606 is compared with the special password stored in the password storage device 14. Here, three external passwords are stored in the floppy disk 16 as a special password, an operator password, an unstored password, or an incorrect password. There are cases. Each case will be described below.

First, when the special password is stored as the external password in the floppy disk 16, the collation between the external password and the special password in step 607 coincides, and the process proceeds to step 609. Step 609
Then, the information processing device main body 12 requests the operator to input a new password through the output device 11, and in response to this,
The operator inputs a new password through the input device 13. Next, the information processing apparatus main body 12 causes the step 610.
And receive this new operator password. Next, in step 611, the information processing apparatus main body 12 performs step 61.
The new operator password received at 0 is stored in the floppy disk 16 through the floppy disk drive 15 as a new external password. Further, in step 612, the operator password in the password storage device 14 is updated to the new operator password received in step 610. After that, the process proceeds to step 605 and the operation permission is given. Note that this operation permission does not necessarily have to be given, as described in the first embodiment.

Next, when the operator password is stored in the floppy disk 16 as an external password,
The collation between the external password and the special password in step 607 does not match, and the process proceeds to step 608. In step 608, the information processing apparatus main body 12 collates the external password read in step 606 with the operator password stored in the password storage device 14. Since the operator password is stored as the external password in the floppy disk 16, the collation with the operator password in step 608 coincides, and the process proceeds to step 609. In step 609, the information processing apparatus main body 12 issues a new password input request to the operator through the output device 11,
In response to this, the operator inputs a new password through the input device 13. Next, in step 610, the information processing apparatus main body 12 receives this new operator password. Next, in step 611, the information processing apparatus main body 12
The new operator password received in step 610 is stored in the floppy disk 16 through the floppy disk drive 15 as a new external password.
Further, in step 612, the operator password in the password storage device 14 is updated to the new operator password received in step 610. After that, the process proceeds to step 605 and the operation permission is given.

If the external password is not stored in the floppy disk 16 or if an incorrect password is stored in the floppy disk 16, the comparison between the external password and the special password in step 607 does not match. Move to step 608. In step 608, the information processing device body 12 determines
External password and password storage device 1 read in 6
It collates with the operator password stored in 4.
Since no external password is stored in the floppy disk 16 or an incorrect password is stored in the floppy disk 16, the collation with the operator password in step 608 does not match, and the process proceeds to step 601. In step 601, the information processing apparatus main body 12 checks whether or not the operator password exists, and since the operator password is set, the process proceeds to step 602. Then, in step 602, a normal operator's input of a password is requested, but the operator does not know the password and cannot obtain the operation permission.

Accordingly, when the special password is stored as the external password in the floppy disk 16 or when the operator password is stored, the operator password is updated in steps 609, 610 and 611. Since it is performed, it is possible to prevent the operator from forgetting to set a new password, and at the same time when the operator password is updated in step 611, a floppy disk for storing the updated operator password is obtained. Even if you forget the updated operator password, you can be sure to deal with it.

If a special password common to all information processing devices is set, a floppy disk storing the special password as an external password is effective for all information processing devices, but this floppy disk is used once. Then, the special password stored as the external password in the floppy disk is replaced with the new operator password that is effective only for this information processing apparatus, so even if this floppy disk is used for another information processing apparatus, The external password and the special password in step 607 do not match, and the external password and the operator password in step 608 do not match, and step 609.
Cannot proceed to the subsequent steps. Therefore, it is possible to prevent illegally updating the password of another information processing apparatus using the same floppy disk, or illegally obtaining operation permission.

Further, if the password is not stored in the floppy disk 16 as the external password, or if an incorrect password is stored, the operation permission cannot be obtained in step 602, and the correct special password is obtained. , Or a person who does not have a floppy disk in which the operator password is stored as an external password, and who does not know the operator password, cannot update the operator password or obtain operation permission. It is prevented that such a person illegally updates the operator password or obtains the operation permission.

Embodiment 6 FIG. Embodiment 6 of the present invention corresponds to claim 6. The hardware configuration of the information processing apparatus according to the sixth embodiment is the same as that of the first embodiment. In FIG. 1, in the sixth embodiment, a floppy disk 16 stores an operator password and operator identification information. For example, a user name and a user ID can be used as the operator identification information. Further, the discriminating means for discriminating whether or not the portable storage means is mounted, the input password collating means, the operator identification information collating means, the external password collating means, the operation permitting means and the operator password updating means are the information processing apparatus main body. 1
2 is realized. Further, the operator password update requesting means is realized by the output device 11 and the information processing device main body 12.

FIG. 7 is a flow chart showing the operation permission process of the information processing apparatus main body 12. The operation of the information processing apparatus according to the sixth embodiment will be described below with reference to FIGS. 1 and 7. When the operator normally tries to obtain the operation permission,
Since the operator remembers the operator password, the floppy disk 16 is not loaded in the floppy disk drive 15. First of all, the information processing apparatus main body 12 is step 7
At 00, the operator is requested to input the operator identification information through the output device 11, and in response to this, the operator inputs the operator identification information through the input device 13. The information processing apparatus main body 12 receives the operator identification information in step 701.
Next, in step 702, it is determined whether or not the floppy disk 16 is present. Since the floppy disk 16 is not loaded, the process proceeds to step 703. Thereafter, in the same manner as in the first embodiment, the operation permission is given to the operator (step 7).
03-707).

Next, when the operator forgets the operator password, the correct password cannot be input in response to the password input request in step 704, so step 706.
When the input password and the operator password are collated with each other, they do not match each other, and it is impossible to move to step 707 and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 702 whether or not the floppy disk 16 is present.
Move to step 708. In step 708, the information processing apparatus body 12 reads the operator identification information from the floppy disk 16 by the floppy disk drive 15.
Next, in step 709, the operator identification information read in step 708 is compared with the operator identification information received in step 701. If the operator identification information stored in the floppy disk 16 and the operator identification information provided by the operator are the same, step 70
The collation in 9 coincides, and the process moves to step 710. After step 710, the external password read from the floppy disk 16 and the operator password are collated in the same manner as in the first embodiment (step 711). If the collation results match, the operator password is updated, Then, the operation is permitted (steps 712 to 714, 707), and if the collation results do not match, the operation is not permitted (steps 703 to 706).

On the other hand, when the operator identification information does not exist in the floppy disk 16 or when different operator identification information is stored, the information processing apparatus main body 12
Then, the collation of the operator identification information in step 709 does not match, and the process proceeds to step 703. In step 703, the information processing apparatus main body 12 checks whether or not the operator password is present. Since the operator password is set, the process proceeds to step 704. Then, in step 704, a normal operator's password input is requested, but since the operator does not know the password, the operation permission cannot be obtained. Therefore, a person who does not have the floppy disk in which the correct operator identification information is stored and who does not know the operator password cannot update the operator password or obtain the operation permission, It is prevented that such a person illegally updates the operator password or obtains the operation permission.

As described above, in the sixth embodiment, the external password collating means performs the collation on the condition that the collation with the operator identification information is performed. Therefore, the operator password is used as the external password. When the operation permission is obtained using the stored floppy disk, a double check is performed to check the operator password and the operator identification information. For example, the external password happens to match the operator password. Even in this case, it is possible to prevent unauthorized operation permission, and it is possible to increase the confidentiality of information when dealing with a forgotten password.

Embodiment 7 FIG. Embodiment 7 of the present invention corresponds to claim 7. The hardware configuration of the information processing apparatus according to the seventh embodiment is the same as that of the first embodiment. In FIG. 1, in the seventh embodiment, the password storage device 14 stores the operator password and the special password, as well as the information processing device identification information uniquely present in each information processing device. As the information processing device identification information, for example, a host name, a host I
D etc. can be used. In addition, a special password is stored as an external password in the floppy disk 16, and the information processing device identification information is also stored. Further, the discriminating means for discriminating whether or not the portable storage means is mounted, the input password collating means, the information processing device identification information collating means, the external password collating means, the operation permitting means, and the operator password updating means are information processing means.

The case where the operator normally tries to obtain the operation permission is the same as that in the first embodiment, and therefore the description thereof is omitted.

If the operator forgets the operator password,
Since a correct password cannot be input in response to the password input request in step 802, the input password and the operator password in step 804 do not match, the process cannot proceed to step 805, and the operation permission cannot be obtained. Then, the operator mounts the floppy disk 16 in the floppy disk drive 15. As a result, the information processing apparatus main body 12 determines in step 800 whether or not the floppy disk 16 is present, and the floppy disk 1
Since No. 6 is attached, the process proceeds from step 800 to step 806. In step 806, the information processing device body 1
A floppy disk drive 15 reads information processing apparatus identification information from the floppy disk 16.
Next, in step 807, the information processing device identification information read in step 806 is compared with the information processing device identification information stored in the password storage device 14.
If the information processing device identification information read from the floppy disk 16 and the information processing device identification information stored in the password storage device 14 are the same, step 8
The collation in 07 matches and the process moves to step 808. After step 808, as in the second embodiment, the external password read from the floppy disk 16 and the operator password are collated (step 809). If the collation results match, the operator password is updated, Then, the operation is permitted (steps 810 to 812, 805). If the collation results do not match, the operation is not permitted (steps 801 to 804).

On the other hand, if the information processing apparatus identification information does not exist in the floppy disk 16 or if different information processing apparatus identification information is stored, the information processing apparatus main body 12 determines the information processing apparatus identification in step 807. The collation of information does not match, and the process moves to step 801. In step 801, the information processing apparatus main body 12 checks whether or not the operator password exists, and since the operator password is set, the process proceeds to step 802. And step 802
However, a normal operator is required to enter a password, but the operator does not know the password and cannot obtain the operation permission. Therefore, a person who does not have the floppy disk in which the correct information processing device identification information is stored and who does not know the operator password cannot update the operator password or obtain the operation permission, It is prevented that such a person illegally updates the operator password or obtains the operation permission.

As described above, in the seventh embodiment, the external password collating means performs the collation on the condition that the collation with the information processing device identification information is performed.
