Abstract

PURPOSE:To provide an information processor checking a password and the input procedure of the password and preventing illegal use or secret leakage. CONSTITUTION:When a power supply switch 1 is turned on, power is supplied to the information processor by a power supply device 2 and a CPU 3 reads out an OS out of a ROM 6 and then checks the password and the information of password procedure data of a RAM 7 backed up by a battery 8. When there is no password setting, operation is continued. When any password was set, an operator inputs the password from a keyboard 5 and in the case of incoincidence between the input data and the password and the input procedure data and the password procedure data, a keyboard controller 4 requests the interruption of supplying power from the power supply device 2 and inhibits key input. In the case of coincidence of the password and the password procedure data, the operation is continued.

In order to solve the above-mentioned problems, an information processing apparatus with security according to the present invention includes a power supply device, a keyboard for inputting various data under the power supply of the power supply device, A reading unit that reads input data input from the keyboard, a procedure reading unit that reads input procedure data that specifies an input order of the input data, a storage unit that stores a password in advance, and an input order of the password. A procedure storing means for storing password procedure data in advance, a comparing means for respectively comparing the input data and the password, and the input procedure data and the password procedure data, and power supply from the power supply device based on the result of the comparing means. A power supply control means for controlling the input data and password or input procedure data and password procedure data. When discrepancies only, and inhibits an access request to stop power supply from the power supply.

Further, the information processing device with security of the present invention is an RO which is backed up by a battery and which has a RAM equipped with the storage means and procedure storage means and an operation system for performing the processing of the comparison means.
It is characterized by being composed of M and.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A security information processing apparatus according to an embodiment of the present invention will be described below with reference to FIG.

As shown in FIG. 1, the information processing apparatus with security according to the present invention turns on / off the power supply 2 for supplying power to the information processing with security and the power supply of the power supply 2. A power switch 1 for controlling, a CPU 3 that receives power from the power supply device 2 and performs various processes, and a CP.
Keyboard 5 for inputting various data according to U3 commands
And a keyboard controller 14 which sends various data from the keyboard 5 to the CPU 3 for control and also has a power supply control means, a system program of the information processing device with security protection, and an operating system (hereinafter referred to as OS) ROM 6 in which the name) is stored,
R for reading and writing various data by the processing of the system program and having storage means and procedure storage means
AM7 and RAM7 backup power supply battery 8
Composed of and.

The operation of the information processing apparatus according to the embodiment of the present invention will be described.

First, when the operator turns on the power switch 1, power is supplied from the power supply device 2 to the information processing device with security so that the CPU 3 first reads the ROM 6
R that was backed up by battery 8 after reading the OS
The password and password procedure data which are the storage information of the storage means and the procedure storage means of the AM 7 are confirmed.

Therefore, if the administrator has not set a password, the operation is continued. On the other hand, if the administrator has set a password, the operator must enter the password from the keyboard 5. Prompt and wait for input from the keyboard 5 while stopped.

When the operator inputs data from the keyboard 5, the input data and the password and the input procedure data and the password procedure data are compared, and if they are correct, the operation is continued.

If the operator makes a wrong key input or does not make a key input, the keyboard controller 4 outputs a command to the power supply device 2 to stop the power supply, thereby supplying power. Stops and key input becomes impossible.

If the administrator sets the password in advance, it will be effective the next time the operation is carried out, and the contents of the password will be set unless the power of the battery 8 backing up the RAM 7 is consumed. Not erased.

Next, a conventional example will be described with reference to the block diagram of the conventional information processing device with security shown in FIG.

As shown in FIG. 2, the conventional information processing apparatus with security control controls the power supply device 12 for supplying power to the information processing apparatus with security protection and the on / off of power supply of the power supply device 12. A power switch 1, a CPU 3 that receives power from the power supply device 12 to perform various processes, and a CP
Keyboard 5 for inputting various data according to U3 commands
And a lock key 19 for prohibiting input on the keyboard 5,
A keyboard controller 14 that sends various data from the keyboard 5 to the CPU 3 for control, and a ROM 1 that stores a system program of the information processing device with security protection.
6, a RAM 7 for reading and writing various data by the processing of the system program, and a battery 8 as a backup power source for the RAM 7.

Here, as shown in FIG. 2, the operation of the conventional information processing device with security is such that the lock key 19 is turned on even when the power switch 12 is turned on and power is supplied from the power supply device 12 to the CPU 3. Therefore, the input from the keyboard 5 is prohibited.

After that, the lock key 19 is turned off by a dedicated key to enable the input from the keyboard 5, and the data input from the keyboard 5 is backed up by the program stored in the ROM 16 and the battery 8 for RA.
It is processed by M7.

If there is any other means for retaining the information regarding the password setting of the information processing device with security according to the embodiment of the present invention, the battery 8 and the RAM.
It is not limited to 7.

[0021]

As described above, according to the information processing apparatus with security of the present invention, even if the power switch of the main body is turned on, the password and the password input procedure are double checked and if they do not match. For example, since the access request is prohibited, it is effective in preventing unauthorized use or leakage of confidential information and preventing data destruction by an unskilled operator.
