Abstract

PURPOSE:To obtain a simplified system enabling a user to access plural data groups continuously without complete execution of password inputs by storing the inputted passwords in a prescribed storing area. CONSTITUTION:A means for storing inputted passwords in a prescribed storing area is formed. If an access request to an information set is inputted to a proccessor 3 through a keyboard 2, a protection code 7 in a file 5 is checked to test whether the information is locked or not. When the protection code 7 is ''1'' and the information is locked, whether a password 8 necessary for the unlocking of the information is included or not in a password stack in a storage device 4 is tested, and when the password 8 is not included, a password input request is displayed on a display 1. When the inputted password coincides with a key necessary for the unlocking, the input password is stored in the password stack and then the information is unlocked. In case of inconsistency, an input request is displayed again on the display 1.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a security control method that releases a series of locks without inputting the same password by setting a temporary storage area called a password stack for storing passwords. It is related to.

[Background of the invention]

Conventional security control methods do not have a password stack to remember the passwords required to access locked data, so the required password must be entered each time the lock is unlocked. There is a drawback in operability.

[Purpose of the invention]

An object of the present invention is to enable a user to access a plurality of data sets consecutively without having to input passwords one after another. This provides a simplified security control method.

[Summary of the invention]

By retaining the input password in a certain storage area, it is possible to access desired data without inputting the password to unlock the next password corresponding to the password being retained.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail with reference to examples. 1st
The figure shows the data security system TR1 method J of the present invention.
This figure shows the construction of the tube wear.

In FIG. 1, 1 is a CRT display device, 2 is an input device such as a keyboard, 3 is a processor, 4 is a storage device that stores passwords, and 5 is a second storage device that stores programs created by each user. (This is a file as a medium.

Figure 2 shows 5 in Figure 1, the file structure.
6 describes the name of the data, and 7 is used as a protection code. The protection code is 1'' when the lock is locked, and 0'' when the lock is released when the corresponding password (1 key) is input. 8 stores a password, which is a key necessary for unlocking, and 9 stores data.

FIG. 3 shows the structure of the storage device shown in FIG. 1 and 4.
The structure is such that passwords are stacked starting from a certain address (@address).

The details of this method will be explained below using the flowchart shown in FIG. At step 10, it is determined whether the user's work is continuing or has ended. If termination is instructed here, the contents of the four storage devices shown in FIG. 1 are erased, and then the work is terminated. When a request to access an information set is issued during work, a check is made to see if the information is locked. This is 1
1, the test is performed by examining the 7 protection code of FIG.

When the protection code is ``0'', password blocking is not set, and when the protection code is ``1'', password blocking is set. If the designated data is locked, check whether password 8 in Figure 2, which is required to unlock the specified data, is included in the password stack in Figure 3. This is 12.

If the password is not included in the password stack, a password input request 13 is displayed on the display device 1 in FIG. 1 to prompt the user to input the password. The password entered in step 13 is the key (password) required to unlock.
Check if it matches. This check is to check whether the input password name matches the password stored at 8 in FIG. 2.

If both passwords match (15), the manual password is stored in the password stack at the stack point SP in FIG. 3, and then the unlocked state (16) is established.

If the two passwords do not match, a password re-entry request message is displayed on the CRT display device 1 in FIG. If the password does not match after re-entering the password a certain number of times, the task is terminated.

By using this system, even if a user starts work and locks some data with a password, that password will be registered in the password stack from the second call during that work period. You can unlock the device without having to re-enter the same password.

[Effects of the Invention] According to the present invention, once a key for unlocking an information set (such as a password) is input during a work period, a password for accessing the same locked information set can be entered. This is effective in simplifying the operation since the process can be performed without any additional steps.

Claims (1)

[Claims] The purpose is to allow only specific users to read and update a set of data handled by an information processing device such as a computer, and a lock such as a password is assigned to the relevant information set in advance and stored. In a mechanism that enables a user to input a key such as a password corresponding to a lock when updating a readout, and to perform processing after confirming that the input key matches a pre-stored lock, one person When a user processes a series of information while sequentially reading and updating multiple pieces of information, the key can be locked to simplify the effort of manually inputting information by one user. It has a storage area that holds input keys, and each time the user inputs a key, the key is added to the storage area, and when the user's processing attempts to read and update the information set, the set is locked. A mechanism for detecting whether a lock has been assigned or not, and when a lock assignment is detected, it is checked whether a key corresponding to the detected lock exists in the key set in the storage area, and if it exists, the lock is released. Information read/update management mechanism that has a mechanism that instructs the user to process the key, and requests the user to input the key only if the key does not exist, and a mechanism that clears the key storage area when the user inputs a process termination instruction.
