When the user selects the 'setting' menu on the execution screen of the hidden view service application, sub menu items of 'setting' are displayed as shown in the screen M110a of FIG. 4, and 'effect' (E.g., deletion, blurring, mosaic, character, etc.) of various hidden effects are displayed on one side of the screen M110b. The user selects one of them and the hidden effect is designated.

5 is a diagram illustrating the hidden effect according to the present invention.

The types of hidden effects illustrated in FIG. 5 are intended to facilitate understanding of the present invention, and the present invention is not limited to the effects listed in FIG. 5 (e.g., deletion, blurring, mosaic, character) Techniques may be employed.

If the user selects one of the 'effect' items (e.g., deletion, blurring, mosaic, character, etc.), the controller 810 performs a hidden process as shown in FIG. 5, Is separately transmitted to the server 200 and stored separately from the entire image.

FIG. 6 is a flowchart illustrating a procedure of performing a hidden view service according to the first embodiment of the present invention.

As shown in FIG. 6, when the hidden view service application is executed and the user selects a specific image, the terminal A 100 displays the selected image on the terminal screen. (S10 to S20)

3, when the user designates a hidden area on the image and selects a kind of hidden processing (e.g., deletion, blurring, mosaic, character), the terminal A 100 first determines The image of the hidden area is stored separately. Then, the hidden process of the selected kind is applied to the hidden area. (S30) FIGS. 3A and 3B respectively designate the face and the chest area on the image as the hidden area, and hide the designated area (hidden area) as the character.

Then, when the hidden processing is completed, the terminal A 100 transmits the image of the hidden area to the server 200 together with the entire image subjected to the hidden processing. (S40) At this time, the terminal A (100) sets the authentication password for restoration of the hidden processing, and then transmits the authentication password to the server (200).

When the image of the hidden area transmitted from the terminal A 100 and the entire image subjected to the hidden processing are transmitted to the server 200, the server 200 divides the received images into different repositories and stores them. (S50)

Thereafter, when another user's terminal (terminal B 300) or the terminal A 100 accesses the server 200 and tries to view or download the hidden image, the server 200 performs a predetermined authentication procedure . (S60, S70, S75) At this time, the authentication password set by the user A is required to pass the authentication procedure.

A terminal (e.g., the terminal B 300 or the terminal A 100) attempting to view or download the hidden image must undergo a login authentication process and then authenticated for image browsing (downloading). The user according to the present invention can browse or download the original image through the two-step authentication process.

If the user of the terminal (for example, the terminal B 300 or the terminal A 100) passes the authentication, the server 200 overlaps the image of the hidden area with the hidden image, And displays it so that it can be viewed by the user, or is downloaded to the user side. (S80, S90). On the other hand, when the user does not pass the authentication, the server 200 directly displays or downloads the hidden image. (S95)

FIG. 7 is a block diagram of a hidden view service system according to a second embodiment of the present invention.

7, the hidden view service system according to the second exemplary embodiment of the present invention includes a terminal A 100, a server 200, and a terminal B 300.

The terminal A 100 executes the hidden view service application and hides the area designated by the user (e.g., the hidden area).

The terminal A 100 can hide the area (e.g., hidden area) designated by the user as hidden processing such as deletion, blurring, mosaic, and character. To this end, the terminal A 100 includes a deletion processing module 186a, a fog processing module 186b, a mosaic processing module 186c, and a character processing module 186d.

The terminal A 100 according to the present exemplary embodiment of the present invention does not separate the image of the designated hidden area from the entire image subjected to the hidden processing and separately stores the image in the server 200, (Hereinafter referred to as " pixel value ") of each pixel in the hidden area according to the hidden processing method to one side or hidden area of the corresponding image. When restoring the original image, the pixel values of the relocated hidden area are restored to their original values by the respective hidden process restoration modules (e.g., 240a, 240b, 240c, and 240d).

Accordingly, the hidden area image of the present example is consequently stored at one side of the image through the relocation procedure.

When the pixel values of the hidden area are relocated to the hidden area (or the image one side), each hidden processing module (e.g., 186a, 186b, 186c, 186d) And relocates it to the calculated position. In restoring the original image, each of the restoration modules (e.g., 240a, 240b, 240c, and 240d) restores the relocated pixels to an original value by using an inverse calculation method using the key value.

The deletion processing module 186a applies pixel values of the image background color to each pixel of the hidden area and then stores the pixel values of the hidden area in one of the upper, So that a frame having a predetermined thickness is formed. 9 (a) shows a frame having a certain thickness formed on the lower side of the image. FIG. 9 is an illustration of images each of which is subjected to hiding according to a second embodiment of the present invention. Instead of rearranging in the frame shape, the present invention may generate a QR code and transmit the pixel values of the hidden area to the server 200 in a QR code.

The pixel values of the hidden area rearranged in the frame shape are restored to the original values again by the deletion restoration module 240a when restoring the original image.

The blurring module 186b relocates the pixel values of the hidden area so that the blurring effect is applied to the image of the hidden area as shown in FIG. 9 (b). The pixel values of the relocated hidden area are restored to the original values by the blurring restoration module 240b upon restoration of the original image.

The mosaic processing module 186c rearranges the pixel values of the hidden area so that the hidden area has a mosaic shape as shown in FIG. 9 (c). The pixel values of the relocated hidden area are restored to their original values by the mosaic restoration module 240c upon restoration of the original image.

The character processing module 186d rearranges the pixel values of the hidden area so that the hidden area has a predetermined character shape as shown in FIG. 9 (d). The pixel values of the rearranged hidden area are restored to their original values by the character restoration module 240d upon restoration of the original image.

The terminal A 100 uploads an image subjected to the hidden processing to the server 200 according to the user's selection. At this time, the terminal A (100) transmits the authentication password for restoring the hidden processing to the server 200 together with the hidden image.

The server 200 temporarily stores the hidden processed images uploaded by the terminal A 100 in a storage. If the other user's terminal (e.g., the terminal B 300 or the terminal A 100) accesses the downloaded (or browsed) image, the authentication process is performed and the password is input .

If the user fails to pass the authentication by inputting the wrong password, the server 200 directly displays (displays) the hidden image or downloads it to the user side.

On the other hand, when the user passes the authentication by inputting the correct password, the server 200 restores the original image by locating the relocated pixels through a restoration procedure corresponding to the hidden processing.

The server 200 includes a deletion restoration module 240a, a fog restoration module 240b, a mosaic restoration module 240c, and a character restoration module 240d as shown in FIG. 7 .

The deletion restoration module 240a restores the pixel values of the hidden area rearranged in a frame shape on the lower side of the image, corresponding to the deletion inhibiting process.

The blur recovery module 240b corresponds to the blurred process, and restores the pixel values of the relocated hidden area back to the original value.

The mosaic restoration module 240c corresponds to the mosaic hidden process and restores the pixel values of the relocated hidden area back to the original value.

The character restoration module 240d restores the pixel values of the relocated hidden area to the original value, corresponding to the character hidden process.

FIG. 8 is a flowchart illustrating a procedure of performing a hidden view service according to a second embodiment of the present invention.

As shown in FIG. 8, when the hidden view service application is executed and the user selects a specific image, the terminal A 100 displays the selected image on the terminal screen. (S100 to S110)

Thereafter, when the user designates the hidden area on the image and selects the kind of hidden processing (e.g., deletion, blurring, mosaic, character) as shown in FIG. 3, The values are relocated to one side of the image or hidden area. (S120 to S130)

When the user selects the hidden processing of the 'delete' function, the terminal A 100 applies the pixel values of the image background color to the pixels of the designated hidden area, and then stores the pixel values of the hidden area in one of the upper, So that a frame having a predetermined thickness is formed.

When the user selects the hidden processing of the 'blur' function, the terminal A (100) relocates the pixel values of the hidden area so that the blurring effect is applied to the image of the designated hidden area.

When the user selects the hidden processing of the 'mosaic' function, the terminal A (100) relocates the pixel values of the hidden area so that the designated hidden area has a mosaic shape.

When the user selects the hidden processing of the 'character' function, the terminal A (100) relocates the pixel values of the hidden area so that the designated hidden area has a predetermined character shape.

When the hidden processing according to the user's selection is completed, the terminal A (100) accesses the server 200 and uploads the hidden image. (S140) At this time, the terminal A (100) transmits the authentication password for restoring the hidden processing together with the hidden image to the server (200).

Then, the server 200 temporarily stores the hidden processed image uploaded by the terminal A 100 in the storage. (S150). If another terminal (e.g., the terminal B 300) or the terminal A 100 accesses and downloads (or browses) the hidden image (S160 & S170) Performs a predetermined authentication procedure and requests the terminal side (100 or 300) to input a password. (S175)

If there is an error in the password input on the terminal side (100 or 300), the user fails to authenticate and the server 200 displays (reads) the hidden image as it is or downloads it to the user side. (S180 & S185)

On the other hand, if there is no error in the password input, the user succeeds in authentication, and the server 200 restores the original image by locating the relocated pixels through a restoration procedure corresponding to the hidden processing. (S190 & S195)
