It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

1 is a flowchart schematically illustrating a process of executing a security file in a computing device according to an embodiment of the present invention, and FIG. 2 is an exemplary view illustrating a screen according to execution of a security file according to an embodiment of the present invention. 3 and 4 are flowcharts illustrating a process of determining a size of a display area according to an exemplary embodiment of the present invention and an exemplary view of the display area.

Prior to describing a method of processing an execution screen of a security file in a computing device with reference to FIG. 1, the security file referred to below is to distinguish a file from a file that is generally processed. Means the file to be applied. In addition, the computing device is a computing device such as a computer, laptop, smart phone, tablet PC, etc., and executes a file such as an image file, a document file, a video file, etc. Output through the display means.

Referring to FIG. 1, the computing device outputs a screen such that only a partial region (hereinafter referred to as a partial region) corresponding to a display region having a specific size among execution screens according to execution of a security file is displayed (S110). Referring to FIG. 2 together, not the entire execution screen 210 is shown, only the display area 230-1, which is a part of the entire screen as shown by reference numeral 220-1, is clearly seen, and the remaining area 240 is shown. Outputs a screen (220-1 or less output screen) to make it appear dim. Of course, this is one embodiment, and according to another embodiment, no contents may be displayed in the screen area 240 except for the display area 230-1, or an image other than the execution screen (see FIG. 4) may be used. It may be displayed.

Here, the first output screen according to the execution of the file may be a screen in which the display area 230-1 exists at a predetermined position as shown by reference numeral 220-1. According to another embodiment, the display area does not exist initially. (Ie, no execution screen is shown), the display area may be displayed at a corresponding position after a user input (for example, touch manipulation of a screen in the case of a touch screen).

In the case of the touch screen, the display area 230-1 may be displayed to correspond to the point where the user's finger touches. According to an example, the touch point of the user may be the center point of the display area. According to another example, the display area may be displayed with the user's finger contact point as the lowest point or the highest point. When the display area is displayed as the contact point as the highest point, the contents of the display area may be partially touched by the finger. It may be hidden.

In addition, the display area 230-1 to be described below including the present embodiment has a circular shape. Of course, this is only one embodiment, and the display area has a shape of any shape displayed on two-dimensional surfaces such as a rectangle and a pentagon. It will be obvious that this can be implemented.

Referring back to FIG. 1, when the user input for the movement of the display area is input from the user and recognizes it (S120), the computing device determines the position of the display area to correspond to the user input (S130). The output screen corresponding to the display area is output (S140). In other words, the user can change the position of the display area, and changing the position changes the display area of the entire execution screen. Referring again to FIG. 2, the display area 230-1 on the output screen 220-1 before the user input is inputted and the display area 230-on the output screen 220-2 after the user input is inputted. The positions of 2) are different from each other, and part of the execution screen shown is changed. Therefore, the user can check only a part of the execution screen, and the user can adjust the portion (display area) displayed through the manipulation of the direction key or the touch of the screen when the screen is the touch screen.

According to this embodiment, since the entire screen is not shown, it is difficult to leak the contents by screen capture and the like, thereby enhancing security, and it is also necessary to perform an inconvenient authentication procedure for the use of a security file such as a separate password input. There will be no.

The display area may vary in size or number depending on various conditions.

Referring to FIG. 3, which illustrates a process of determining a size, such as a size or number of display areas, the computing device checks a security level set in a security file (S310). According to an example, the computing device may check the security level recorded in the header of the security file, or in another example, the security level may be assigned to a specific server by using identification information (for example, a file name) of the security file. You can also contact us.

The computing device confirming the security level of the security file determines the size of the display area corresponding to the security level (S320). For example, a display area standard according to each security level may be set in advance, and a computing device having related information may determine the display area standard according to the security level of the identified security file.

The computing device outputs an output screen to which the display area according to the determined display area standard is applied (S330).

Referring to FIG. 4, which illustrates a display area, in the case of a security file having a relatively high security level of 1, an output screen having a display area 410 having a relatively small size (that is, area) is displayed. In contrast, a security file having a relatively low security level has a larger display area 420. According to this, the lower the security level is, the wider the area of the execution screen is.

Although not shown in the drawing, the number of display areas may vary depending on the security level. For example, when the security level is 3 level, an output screen in which two display areas, such as reference number 420, are displayed at different positions may be displayed. Of course, when there are a plurality of display areas, the user may adjust the position of each display area.

As shown in the figure, other contents other than the execution screen may be displayed in the remaining area 430 (hereinafter, referred to as the margin area) of the screen except for the display area 410. For example, a preset picture is displayed. Alternatively, the computing device may use the blank area for various purposes. For example, a still image or a video corresponding to the type of security file (for example, document, image, video, etc.) may be displayed in the blank area. As another example, the computing device may display advertisement data (which may be a still image or a moving image, of course), which is stored or received from a predetermined server, in the margin area. The above examples are not limited to the exemplary embodiments, and the blank area may be used for various purposes.

In the embodiment of FIG. 3, the size of the display area varies according to the security level of the security file. According to another embodiment, the display area standard may vary according to the type of the security file. As an easy example, the display area standard may vary depending on whether the security file is a document, image, video, etc., or what file format among the documents (for example, a general document creation file such as Korean, MS Word, or MS Excel). (Excel) recognition, etc.) may be determined.

According to another embodiment, the display area specification may vary according to the security level of the user or the location of the computing device. For example, the computing device may execute a security file only when a user performs an authentication procedure with a specific server, and determines the specification of the display area according to the user's membership level according to the authentication procedure.

According to an embodiment according to the location of the computing device, the computing device measures the current location using a GPS receiver, etc., and compares the measured current location with location information set in the security file to determine the security level. The size of the display area varies depending on the grade. For example, if the information of [Seoul area-3 grade, Gyeonggi-do-2 grade, rest-1 grade] is set in the security file, the security level of the security file is determined according to which region the current location of the computing device is measured. To decide.

So far, the execution screen processing method according to the security file in the computing device has been described. Hereinafter, the processing of the execution screen in the terminal device when the server provides the security file to the terminal device connected through the communication network according to another embodiment will be described.
