Description

{Method for securing computer file}

The present invention relates to a security method of a computer file, and more specifically, to install a security-only program and then run the program to select a file or folder requiring security and to set a predetermined security function option for the selected file or folder. The present invention relates to a method of securing computer files that can secure computer files or folders.

When using a computer, various files are used, such as writing a document file using a word processor tool, drawing a picture file using a graphic tool, or designing an electric circuit using a circuit design tool. The aspects are very diverse.

However, in the operation of such a file, it is often required to secure externally personally or work. In general, such security is performed through the file password setting function provided by the above tools, or the entire folder is secured by including a hidden function in a folder to which the file is required to be secured.

Such file security is becoming more important nowadays as computers are networked through the Internet, and each company has installed a firewall to prevent intrusion from the external network. However, due to the complexity of the firewall installation and the rising cost of installation, it is difficult to use the firewall in small businesses, and even if the firewall is installed, there is always a possibility of information leakage from the company, and not all the tools provide the file password setting function. The files supported by these tools can be helpless for information leakage.

Therefore, the present invention has been made in view of the above-mentioned needs and problems, and an object of the present invention is to provide a computer with a security-only program to selectively select files or folders requiring security, and then set predetermined security function options. The present invention provides a security method of a computer file that can prevent the leakage of information to others by securing the computer file in a manner.

In order to achieve the above object, the security method of the computer file of the present invention includes the steps of a user inputting an ID and password for security, a step of checking whether the user is currently operating a security function, and a user setting a security option to newly secure the security file. It includes the step of setting.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, it is assumed that the present invention is implemented in the Windows OS operating system.

The implementation of the present invention first requires the process of installing the above-described security-only program on a computer, and the installation can be prevented that the user can arbitrarily delete the security-only program by using the control panel instead of the program file folder.

1 is a flowchart in which the present invention is implemented.

The user inputting a security ID and password (S1) is a preliminary step that the user takes to set new security on a specific file or folder or check whether the security function is in operation. The window shown in 2 will appear, and the user will enter his ID and password. The password can be set to various encryption methods such as 64-bit and 128-bit methods. At this time, multiple ID and password can be supported in one security-only program. This can be done by making individual ID and password data into DB. This can also be very handy when you need to share a particular file with a particular person, for example, when a single computer is used by multiple people. In addition, security-only programs are designed to run automatically when the computer boots and to recommend security settings when the computer shuts down so that users can be alerted to the security of their files at any time while using the computer. desirable.

In step S1, the user reaches a step S2 of confirming whether the security function is operated. An example of this is illustrated in FIGS. 3A and 3B. This is a step in which a window is displayed on the computer indicating whether the security function is currently active or not, and the user checks the current security status.

In the step S3 of newly setting security by setting the security option by the user, when the user clicks the OK button in step S2, the state of the set security other than the setting window shown in FIG. 4 is shown on the screen of the computer. In this state, the user can select a new file or folder that needs security and set security options to secure the file or folder or release the preset security.

At this time, the selection of a file or folder that requires security can be selected by placing a 'V' mark in the check box portion preceding the folder name or the file name as shown in FIG. 4 (only a function of selecting a folder is illustrated here). The security option setting specifies the level of security for the selected file or folder, which is a list of fully locked (not read / write), read-only, secured files or folders (where the screen is shown in FIG. 4). Options, such as a window), and the list of files or folders for which security options are specified is not displayed at all even if the explorer supported by the Windows OS is opened except when the above program is started. Full security of specified files or folders is possible.

In this step (S3), the user can also change the preset password, and if the password is lost, password recovery can be used to recover the password by using a password inference technique. It is possible by entering a phrase that can be. An illustration of this is shown in FIG. 5.

You can cancel the preset security by deleting the 'V' mark in the check box in front of the folder name or the file name.In addition, the batch release function that allows you to temporarily select and release multiple security files or folders. It is possible.

Although the preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that the present invention may be modified without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Thus, modifications to the foregoing embodiments of the invention will not depart from the teachings of the invention.

Use of the present invention has the following advantages.

Since security can be achieved through general computer programs, the cost of building a conventional security (for example, building a firewall) can be reduced, and as shown in FIG. 1D, the screen of option setting has a structure such as a window explorer. Anyone can easily set up security for their files.

Claims (4)

In a method of securing computer files using a security-only program: A first user inputting a security ID and password that can be multiplely supported in one security-only program in order for the computer user to newly set security on a specific file or folder embedded in the computer or to check whether a security function is in operation; step; A second step of checking whether the security function is in operation by looking at a window indicating whether the security function displayed on the computer is operated; And And a third step of allowing the user to select a new file or folder requiring security to set a security option or to release a preset security.
