Description

[Detailed description of the invention] Automatic protection processing of information data and a device for executing the same This invention relates to automatic protection processing of information data processed by information processing means similar to the above.

The data to be protected may be stored on the hard disk of the information processing means, for example. It's like data.

The invention also relates to a device for carrying out this process.

With the present invention, data protection is provided by peripheral storage devices such as magnetic tape or printers. This is done by storing these data using a storage support means. Traditional de Computer programs and protection support devices are generally used for data protection processing. the current, The most frequently used protection aids are the classic disk, Winchester-type devices. discs, magnetic tapes, optical discs, etc. The program used includes two There is a type. The first type is the so-called disk operating system. Using information processing means using C0PY in DO3, which is a copy under system management. A group of control programs integrated into the system for This process is protected It is not allowed to memorize reference items of files that are used in the order is requested.

The second type of protection program is a subprogram that stores references to the files being protected. Programs and Operating Systems - Using the procedures of the system or its control programs. It consists of a protection sub-product for use.

The use of such protection programs necessarily requires preparation, loading of the program, The information processing that will be used will involve the intervention of an external operator, such as starting a program. complicating the process of using administrative means.

The purpose of the present invention is to provide processing for protecting information data that overcomes the drawbacks of conventional processing. and, in particular, by preliminary storage of references to protected files. Enables automatic, systematic and programmable protection.

The alphanumeric references or reference numbers of the equipment and their connections shall be It is used to differentiate and standardize equipment. used in the example described The numerical values of the various passive devices are further purely exemplary. Also, as a practical matter All indicated different equipment connections indicated by Vcc are not shown. It is connected to the positive terminal of the DC power supply of device 4. Here, the protection device 4 according to the invention Describe the behavior. In particular, detection and execution of protection requests as shown in Figures 6A and 6B. is written in conjunction with a flow chart of a program for.

Activation of switch 7 (see Figure 2) triggers monostable circuit 18 at "H'," Its output Q subsequently changes from 0 to 1, and after a time delay, from 1 to 0. Ru. It consists of the winding 12a of the relay 12 (see Figure 4) and the output of the NOR gate 19. This is done by the rectification of the transistor 25 interconnected between the power and the power. By this Therefore, the power supply to the sector S is cut off before the power supply voltage is turned on again after a time delay.

Similarly, said actuation of switch 7 triggers monostable circuit 24 to flip the JK flip. Set clock 1 of flop 17 and relay 20 for confirmation of protection request. change the direction of current in the transistor 26 (see Figure 4) which controls the winding 20a of the . In this way, the contact 20b of the relay 20 is connected to the microcomputer 1. Set the 5th bit of the status register of interface gate 9 to “1” do. At the end of the protection process, the interface game of microcomputer 1 Setting “1” to bit 908 and protection device 4 interface gate 8 These settings set the output of the NAND game (with 8 inputs) 21a to “0”. cut. This signal is inverted by the NAND gate 22 and outputs the monostable circuit 24 as “ Set to H'. The output Q' of the monostable circuit 24 changes from "1" to 0", and After a time delay to allow the buffer memory of printer 2 to energize, 1”. This latter signal is combined at the output of the NAND gate 21. It is used as an input to the NANO gate 23 and sets the output of this gate 23 to "L". It constitutes the clock signal for the JK flip-flop 17. Flipf The output of the loop 17 obtains a value of “1” and triggers the control sector relay 12 to Finally, power is supplied to the microcomputer 1, instruction printer 2, and protection support device 3. Cut off.

In summary, it can be seen that the operation of the protection device 4 is as follows.

1. At the stage of detecting a protection request from the microcomputer 1, the interface The data of gate 8 is set to 255 at the end. If a protection request is made, device 4 If detected, the fifth bit of the status register of microcomputer 1 Set 1″ to .

- During the end of protection detection phase, the sector ensures that the device is powered down. For the timing before setting “1” to the JK flip-flop 170 input, Accordingly, the microcomputer inputs the data of interface gate 8 for more than 5 seconds. Set the computer to 255.

- Apart from these two sets of stages, gates 9 and 10 are electrically isolated from the device 4 by circuits 9a, 10a (see Figure 4). There is.

The invention thus provides an electrical protection device with simple concept and implementation. , in cooperation with the protection program, allows automatic execution of one operation of the control device. to the unusable memory of a microcomputer or such device.
