Description

An apparatus and method for preventing the pirated copy of software program}

The present invention is to prevent illegal copying of software, and more specifically, the main function provided in one software is selected only by a very large number of character codes, so that the main function of the program cannot be performed during illegal copying of software. In addition, the present invention relates to an apparatus and a method for preventing illegal use of a program that can maximize the difficulty in decrypting a secret code corresponding to a corresponding character.

In general, unauthorized copying of software is made by hackers, and exponential distribution of software is achieved. Therefore, programmers are developing more advanced lock programs to protect their intellectual property. Such a lock program is divided into a software method and a hardware method. First, a software lock program is as follows.

First, there is an Over Format technique, which formats a larger number of tracks than standard tracks when formatting a disk, stores arbitrary information there, and then executes the program when the program is run. Check the copy and original from The second is the unformat technique. Unlike the over-format technique, this does not format a certain track of the disc, and is a technique using a disc that must be formatted when copying a program.

Third, there is an over sector technique and an unsector technique, in which a track used in the over format and unformat technique is used for a sector. This increases the number of eight sectors per track of the disk to ten or eleven, or does not create a specific sector of the original disk to facilitate identification with the copy disk.

Such a software lock program has continually developed, and many programs are used in addition to the above-described techniques. On the other hand, unlike software lock programs, there are hardware techniques that are quite difficult to copy, allowing the execution of programs through software and certain hardware devices.

As the lock device using the hardware, a method of performing a lock function from the presence or absence of a hardware device, a method of storing information in the hardware device and checking the program when the program is executed, and a method of storing some data of the program are used.

However, the lock program using the above-described hardware has a low frequency of use as a high cost is required, and also causes a problem that unlocking can be performed by eliminating a routine for checking such a hardware device. In addition, the software lock program also uses a copy-only program or a separate device is easily unlocked from hackers. Therefore, the protection of intellectual property becomes more urgent as the illegal copying of software continues.

The present invention was created to solve the above problems, and an object of the present invention is to provide an apparatus and method for preventing illegal use of a program that can prevent illegal copying of software.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a first embodiment of the present invention, which is a block diagram having a separate button. FIG. 2 is a block diagram illustrating in detail the code generation unit of FIG. 1. First, the present invention with reference to FIG. 1 includes a software for allowing a function selection of a specific menu to be made through a plurality of consecutive codes, and then a separate button for selecting a specific function of the software. Switching unit 110 for outputting using the code, Code generation unit 112 for enabling a specific function of the software by generating a plurality of consecutive codes based on the switching unit 110, and the code Computer hardware, i.e., an input / output port 114, a central processing unit 116, and a memory for storing copy protection programs for allowing a plurality of code signals generated by the generation unit 112 to be applied to a computer, are stored.

In addition, the output terminal of the input / output port 114 is provided with a video port 120 for outputting a video signal to the CRT (CRT), the code generator 112 is a code storage unit 214 is stored a plurality of codes ), A controller 212 for overall control of the system so that the stored data of the code storage unit 214 can be read according to an input condition, and a serial for serially transmitting the stored data of the code storage unit 214. The output unit 216 and the pulse supply unit 210 for synchronous control of the system.

Hereinafter, the operation of the present invention according to the above configuration will be described.

For example, when a user purchases a copy protection program 'Hangul Windows' and installs it on his computer, and the Hangul window has a predetermined function for copy protection. For example, 'open file' or 'save file' to 'end' It is assumed that a function such as' is programmed to display the function by a specific signal. In addition, the specific signal means a plurality of key input signals such as' Alt-C, T, G, B, 3, 4, W, R, B, N, T, X, X, X, 'to' enter. Multiple consecutive key signals such as keys, shift keys,%, $, @ .... 'may be taken as an example. That is, in order for the user to perform 'open file' to use the 'Hangul window', the plurality of key signals must be continuously input.

Of course, in the input of such a key signal, even if the user does not input the key signal directly by adding a predetermined extremely short operation time, the present invention will not depart from the gist of the present invention.

The user installs such a copy-protection program in the memory 118, and the central processing unit 116 performs an initial function of the program. In installing the program, the control command a is sent to the second port P2 of the I / O port 114 mounted in the computer through a keyboard provided in the switching unit 110. Enter it. The CPU 116 continuously controls to use the second port P2 of the input / output port 114 to receive a command from the keyboard of the switching unit 110.

In other words, in installing the program, the duplication is possible by the usual procedure. However, when the user performs 'open file' to use the installed program, the user operates a button provided separately in the switching unit 110. In this case, the switching signal b generated by the button is input to the controller 212 and transmits the control signal g to the code storage unit 214 in which a plurality of codes are stored. The control unit 212 generates a predetermined output signal j to inform the central processing unit 116 of the computer that the current button signal is input.

As a result, the central processing unit 116 outputs a control signal e to the input / output port 114 to control the gate of the input port. The control signal e blocks the signal flowing through the second port P2 and allows the signal to flow through the first port P1.

In this case, the plurality of data stored in the code storage unit 214 outputs data based on the synchronization signal f of the pulse supply unit 210 (h). The data is applied to the serial output unit 216, and the control unit 212 applies a control signal i to transmit the data flowing in the serial output unit 216 in series. Accordingly, the serial output unit 216 transmits a plurality of data stored in the code storage unit 214 to the first port P1 of the input / output port 114.

The central processing unit 116 receives a plurality of serial code data flowing through the input and output port 114, this continuous code is to select the 'open file' function of the 'Korean window'.

On the other hand, as a second embodiment of the present invention, a case where you want to perform this function through the existing keyboard without a separate button described above are as follows.

3 is a block diagram according to a second embodiment of the present invention. 4 is a block diagram for describing the code generator of FIG. 3 in more detail. 5 is a flowchart for describing an operation state of the controller of FIG. 4. First, the present invention with reference to FIGS. 3 and 4 is not provided with a separate button, and is provided with a switching unit 310 for generating a plurality of commands by a keyboard, and connected in series with the switching unit 310 to specify a program. A code generator 312 for generating a corresponding code for performing a function, an input / output port 314 and a central processing unit 116 provided to allow a code generated by the code generator 312 to flow into a computer. ), Memory 118, and video port 120.

The code generator 312 detects a pulse supply unit 414 for performing synchronous control, a controller 416 for overall control of the system, and a specific switching signal flowing from the switching unit 310. In order to compare the data storage unit 420 for storing the data for detection, the comparison unit 418 for mutually comparing the stored data of the data storage unit 420 and the currently input switching signal, a code stored a plurality of codes A storage unit 422 and a serial output unit 424 for serially transmitting the data of the code storage unit 422.

On the other hand, the key signal generated in the switching unit 110 and the code data generated in the code storage unit 422 is 3S-buffer (3-State buffer: 412) to be smoothly transmitted to the input and output port 314 of the computer Is provided.

Hereinafter, the operation of the present invention according to the above configuration will be described with reference to FIG. 5.

The user installs the 'Korean window' through the switching unit 310. A plurality of commands for installation are introduced to the code generator 312, the control unit 416 provided in the code generator 312 detects whether a specific command, that is, a specific key signal of the keyboard when the current command is input. .

The specific command is already stored in the data storage unit 420, and the controller 416 compares the currently introduced command with the command stored in the data storage unit 420. The controller 416 outputs a control signal according to the data comparison to the comparator 418 and simultaneously controls the data of the data storage 420 to be transmitted to the comparator 418.

If the user inputs a command for installing a program without inputting a specific key signal, the controller 416 determines that the key signal is not a specific key signal through the data storage unit 420 and the comparison unit 418. Recognize. Therefore, the controller 416 outputs a low level signal to the 3S-buffer 412. This is to transmit a switching signal (a) generated by the switching unit 310, that is, a plurality of commands (c) to the input / output port 314 of the computer.

Accordingly, the command flowing into the input / output port 314 installs a 'Korean window' as the command d is transmitted to the CPU 116 (step S101). The program installed as described above allows the user to select a start menu. For example, when a user wants to open a file, a specific key provided in the keyboard is operated (step S103).

The key signal is input to the controller 416, and the controller 416 reads the stored data of the data storage unit 420 to determine whether the currently input key signal is a key signal that is already set. In step 418, it is determined whether mutual data are the same (S105 and S107). At this time, when the determination result of the controller 416 determines that the data generated by the switching unit 310 and the data stored in the data storage unit 420 are the same, the high level signal is output to the 3S-buffer 412. do.

The 3S-buffer 412 blocks the switching signal output from the switching unit 310 and is controlled to transmit the signal output from the serial output unit 424 to the input / output port of the computer. At this time, the control unit 416 controls to transmit a plurality of codes stored in the code storage unit 422, that is, a plurality of character data shown as an example in the first embodiment, to the serial output unit 424.

Data output from the code storage unit 422 is transmitted in parallel, and the serial output unit 424 is serially output according to the pulse signal obtained from the pulse supply unit 414. The output signal of the serial output unit 424 is applied to the 3S-buffer 412, and since the control unit 416 enables the 3S-buffer 412 as a high level, the code storage unit 422 The stored plurality of code data is transmitted to the input / output port 314 (step S109).

The CPU 116 receives the code data and performs the 'open file' function of the 'Korean window'. 'Alt-C, T, G, B, 3,4, W, R, B, N, T, X, X, X' is an example of performing 'open file' function through 'Alt-O'. 'Open file' function through a plurality of character data, such as ',' (step S111).

That is, in selecting the main function of the program, it is possible to be made through a very complex character input, and when the user selects a specific key, the code generator 312 is to output a plurality of codes.

Therefore, the developed program can be freely distributed, and the original program can use a predetermined board including the code generator 312 to prevent unauthorized copying of the program.

The present invention described above is programmed to select main functions used in one piece of software by a plurality of character data, and includes a code generator so that a plurality of character data can be easily selected by a user. By disabling the function, it is possible to prevent unauthorized copying of intellectual property.

In the above, the present invention has been described in detail with reference to the above-described embodiments, but the apparatus and method for preventing illegal use of the present inventors are not limited thereto, and instead of a series of character codes, a series of digital codes that are binarized are used. Modifications or improvements are possible within the ordinary knowledge of those skilled in the art.
