The present invention relates to a security management method of an electronic drawing and a recording medium for recording a program for implementing the same. The present invention relates to a security management method of an electronic drawing capable of systematically maintaining security for drawings requested by a user by providing an installation file for creating an execution program, and a recording medium recording a program for implementing the same.

Drawing design has become electronic drawing (CAD) due to the rapid spread of computers, and in recent years, with the explosive increase of the Internet use population, various electronic drawings are rapidly leaking on the Internet. In addition, in the case of electronic drawing preparation, most of the ordering companies make a drawing request to a service company, and a service provider prepares an electronic drawing and supplies it to the ordering company.

Therefore, irrespective of the ordering company's intention, important design drawings are leaked and copied outside, and important technical contents are not protected properly.

In particular, the design work of national projects related to large-scale design, high-tech equipment, semiconductor-related equipment, military buildings, electrical facilities, and national public facilities will inevitably damage the electronic drawings. Therefore, design security in these areas must be accompanied by drawing security system.

Thus, a security system was introduced so that only the person who entered the correct password by opening a password in the drawing file itself could open the electronic drawings.However, if the password itself is leaked, the security system itself will be destroyed and the important electronic drawings will be leaked. A problem that cannot be prevented has occurred. In particular, there is no system that can fundamentally prevent the outsourcing of contractors from contracting out electronic drawings.

In addition, although the contents related to the electronic drawing exchange system have been recently introduced, the prior art focuses only on the external leakage that may occur when the drawing file is transferred between the client and the service company. There was a problem that could not fundamentally block the possibility of leaking.

The present invention is to solve the above problems, while running the existing application program that can create an electronic drawing as an installation file that can generate an executable program for performing the drawing operation and encryption in the encrypted drawing file; The purpose of the present invention is to provide an electronic drawing security management method capable of systematically maintaining security for drawings requested by an administrator to a user, and a recording medium recording a program for implementing the same.

In addition, it is easy to create installation files to distribute to users, manage the history of distribution of installation files to users, control the commands of application programs related to drawing leakage, and the process of user's drawing work. It can be searched as a log file, and the other purpose is to be able to decode the delivered drawing file into an electronic drawing and a log file.

In order to achieve the above object, the electronic drawing security management method of the present invention comprises the steps of: an administrator registering a user by setting a license period; And generating an installation file in which the license period is set, and encrypting a drawing file, wherein the installation file is a drawing operation in the encrypted drawing file while driving an application program capable of creating an existing electronic drawing as it is. Characterized by generating an executable program to perform and encrypt.

On the other hand, the recording medium recording a program for implementing the electronic drawing security management method of the present invention, the step of registering the user by setting the license period of the administrator; And generating an installation file in which the license period is set, and encrypting a drawing file, wherein the installation file is a drawing operation in the encrypted drawing file while driving an application program capable of creating an existing electronic drawing as it is. To implement the electronic drawing security management method, characterized in that for generating an executable program for performing and encrypting.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

Electronic drawing security management method according to a preferred embodiment of the present invention, the license period setting and user registration step (S10) as shown in Figure 1a and 1b; Installation file creation (S20) and drawing file encryption step (S30).

As the manager terminal 1 and the user terminal 5, any type of PC or terminal can be used as long as the device has a processing function capable of supporting a program, and the actual electronic drawing security management is built in the manager terminal 1, and the user The terminal 5 executes the distributed installation file and generates an execution program for performing drawing operations on the encrypted drawing file and encrypting the same while using an application program for creating an existing electronic drawing, and using the execution program. It serves to complete the drawing file.

When the administrator installs and executes a program for implementing the electronic drawing security management method on the manager terminal 1, a screen as shown in FIG. 2 is displayed. When the administrator clicks the user management (10), the name of the company who has distributed the installation file in the meantime is displayed on the left to manage the history of the installation file distribution. Click (11) to register the information on the user by entering the license period, management code, company name and service name, etc. (S10).

After the user registration (S10) with the license period set as described above is completed, installation file creation 12 is activated, and when the installation file creation 12 is clicked on, the administrator terminal 1 is designated as shown in FIG. An installation file (IntelliDosInstall.exe, etc.) to be distributed to the user is created in the directory (S20). In this case, the installation file may be executed in the user terminal only during the license period specified in the proxy such as a user to generate an execution program.

In addition, when the format management 20 is clicked to encrypt the drawing file to be distributed to the user together with the installation file, as shown in FIG. 4, a directory of the administrator terminal 1 is displayed on the left side, and a directory exists on the right side. A drawing file with an extension of dwg is displayed, and a drawing file to be distributed to a user is selected and encrypted (S30). Therefore, due to the encryption of the drawing file, it is possible to block access to the drawing file of the general public and to suppress the use beyond the authority of the user.

At this time, the encryption algorithm uses a symmetric encryption algorithm, which is a 128-bit DES3 encryption module, but any encryption algorithm that can be decrypted regardless of symmetric or asymmetric may be used.

The administrator distributes the installation file and the encrypted drawing file to the user (S40). As a distribution method, a variety of methods may be used, such as transmitting a file using a communication network such as the Internet, or uploading a file for a user to download from a designated website.

Since the distributed drawing file is encrypted, a user cannot open the drawing file with an application program (AutoCAD) that can create an existing electronic drawing in the user terminal 5 and perform a drawing operation at all. Therefore, the user must first execute the distributed installation file and select a version corresponding to the application program (FIG. 3), and generate an execution program (IntelliDOS) as shown in FIG. 5 (S50). At this time, the execution program not only uses the module of an application program that can create an existing electronic drawing as it is, but also continuously encrypts and manages the drawing file in which the user works. In other words, the module for drawing creation controls the commands (such as saving as other name) related to the drawing leak among the commands for drawing drawing generally used in the application program while using the application program as it is. By continuously encrypting the password, you can block the public's access and prevent the user's unauthorized use.

If the application program is AutoCAD, after the executable program written in LISP and / or Visual C ++ is installed, the user executes the drawing work in the drawing file by using the executable program using the module of the application as shown in FIG. (S60). In other words, AutoCAD commands are executed as preset, controlled by executable programs written in LISP and / or Visual C ++. In addition, although the drawing may be performed by opening the unencrypted drawing using the executable program, the drawing file worked using the executable program is automatically encrypted and stored so that the drawing file cannot be opened by another application. .

The execution program not only continuously encrypts and manages the drawing file but also stores the process of the user's drawing work in the drawing file as a log file. At this time, the log file records the date when the file was first encrypted, the number of prints of the drawing, and the work contents of the drawing. When the user outputs the drawing while drawing, the drawing file must be saved to use the printer. This function allows you to print and display the number of prints on the label of the drawing so that you can check the output drawings and saved drawing files. This can prevent a mismatch between the output drawing and the finished drawing file that the user delivers to the manager.

After the license period set at the time of user registration, the user can no longer use the executable program. Therefore, a new installation file must be distributed to the administrator. This prevents users from using drawing files after the license period has passed.

After completing the drawing file using the execution program, the user delivers the completed drawing file (S70). The delivery method can be delivered in the same manner as the administrator distributes the installation file and the drawing file to the user.

The administrator designates the drawing file and clicks the log search 30, so that the user can inquire the drawing work performed in the drawing file as shown in FIG. 7 (S80), and only the log file is a separate document file. Can be stored as At this time, you can search the contents recorded in log files such as user information, working date, drawing output frequency, etc., to check whether the user performed drawing work while observing the security of drawing thoroughly, and the user performs drawing work effectively. It can also be used as a data for evaluating the design ability of a user who is a user.

In addition, the administrator may decrypt the delivered drawing file as shown in FIG. 8 and separate it into an electronic drawing and a log file (S90). This has the advantage that the drawing file can be conveniently used by the internal personnel of the administrator.

Although the above-described preferred embodiment is described with reference to AutoCAD, an electronic drawing creating application, it can be applied to various applications such as an application for creating an important plan or presentation material requiring security as well as other electronic drawing drawing applications. Could be.

The above description is merely illustrative of the technical spirit of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the claims below, and all technical ideas within the scope of the claims should be construed as being included in the scope of the present invention.

As described above, according to the present invention, since the administrator can systematically manage the installation file and the drawing file distributed to the user, there is an effect that security management of the electronic drawings can be thoroughly maintained.

Inquiry of the drawing work performed by the user in the log file can be used as a material to objectively evaluate the user's drawing design ability.

In addition, since the manager can systematically manage the overall electronic drawings, the technical contents of the manager can be systematically protected.
