Description

System for providing wallpaper replacement service through communication network {Advertising System With Exchangeable Wallpaper Via Internet}

The present invention relates to an advertisement method through a communication network, in particular, the Internet, and more specifically, an advertisement is displayed on a desktop which is not a part of a user monitor, and at the same time, the desktop is changed using a desktop of the computer monitor. It relates to an advertising method.

Until now, the process of encountering a particular advertisement by a computer user over a communication network, especially the Internet, can only occur after the user turns on the computer, accesses the Internet, automatically or manually launches a web browser, and then accesses the advertising agency's website. It was. In addition, the advertisement form on the advertisement agency's website is in the form of a linked banner or text appearing at a predetermined position on a monitor that is widely known, and the user is clicked on the link to connect to the company's website. .

Recently, in order to solve the disadvantages of the passive advertising technique, an advertisement technique using a user's wallpaper as an advertisement screen has appeared, and the present invention belongs to the category of an advertisement method using the wallpaper.

An example of such an advertisement method using a computer wallpaper is Korean Patent Application No. 99-73129 (hereinafter referred to as '129 patent application'). Referring to the '129 patent application, the user's computer operating system changes the screen change system of the computer by changing at least one of the start and end screen, the desktop and screen save screen files of the user computer, or the sound files at the computer startup and shutdown A technology for changing a screen or sound file downloaded through the Internet to allow a user to access the changed screen or sound is disclosed. 6 shows a brief flowchart of an advertisement method according to the conventional method.

Looking at the '129 patent application in more detail, there is a push server 24 for delivering the above-mentioned various screen files or sound files to the user computer, the user computer is connected to the Internet, the server 24 After downloading and storing the screen or sound file through the change of the control portion of their operating system to display the corresponding advertisement screen on the user's computer monitor.

Of course, the server 24 includes a member information storage unit, a server control unit, an advertiser information storage unit, an update file storage unit, etc. to classify the advertisement targets and to push corresponding files, and to allow the user to click on the advertisement. It constantly checks the time, date, etc., pays users for the advertisements, and allows advertisers to understand their advertising volume.

In addition to these advertising methods, when a user clicks on a banner or text that links to the advertiser's website, the user checks the number of clicks or the time of viewing the advertiser's webpage by clicking on it, and the user receives a predetermined amount of prize money for the accumulated amount. In addition, by providing a product, and providing an accurate number of user clicks to the advertiser to help determine the actual amount of advertising.

However, according to the advertisement method using the conventional background screen including the '129 patent application, since the user adopts a method of linking the corresponding websites of each advertiser on the background screen, the user is listed on the background screen. It is inconvenient to access the corresponding advertiser website and view the web page only by clicking the desired advertisement link among the links. In particular, when a user clicks a link on the desktop, he or she usually connects to the company's 'home page', and the user must click the link displayed on the 'home page' again to see the desired information. Page search is possible.

In addition, when looking at the specific technical idea of the conventional wallpaper advertisement method, it is possible to use the HTML document as a background screen which is one of the active desktop functions of Windows of the United States, which is currently used as the operating system of most personal computers. In this case, the file downloaded from the push server 24 is set as the desktop by default. However, if the user manually cancels the active desktop function at any time, the user returns to the desktop set by the original user. There is a problem that the user does not know whether the user is actually viewing an advertisement because the push server 24 does not recognize it.

The present invention is to solve the drawbacks derived from the above-described advertising method using the conventional wallpaper, and does not display a separate advertising screen linked to a plurality of advertiser web pages on the desktop, the advertiser's corresponding web page All, specifically, the advertiser's 'home page' is displayed on the desktop, and it can be replaced at regular intervals to make the web page search faster. Even if you turn off the system, it will be immediately recognized and forced to be reactivated so that the advertiser's web page is always displayed on the desktop when the user's computer is connected to the server. The purpose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described by way of example only with reference to the accompanying drawings. In the following description, a personal computer operating system and a web browser will be described using Microsoft's Windows 98 and Internet Explorer 5.0 as an example, and the communication between the server and the user's computer uses the HTTP protocol.

Referring to FIG. 1, an overall schematic diagram of a wallpaper replacement service system according to the present invention is shown.

The advertisement information storing means 110 of the web server 100 shown in FIG. 1 stores and manages a web page of an advertiser website registered in a service according to the present invention in the form of a web file. The web file is stored in HTML format so that it can be set as a desktop according to the user's computer operating system. In this specification, the stored file will be collectively referred to as 'ilovesoft.htm file', and the same expression will be used below. . Each of the ilovesoft.htm files is appropriately the homepage of each advertiser.

2 is a flowchart illustrating an operation process of the web server 100. In a suitable embodiment according to the invention, the operation of the web server 100 begins with a user identification step 111. As will be described later in the operation process of the user computer 200, the user identification step 111 is a unique software that enables the user computer 200 to implement the advertisement according to the present invention by connecting to the web server 100 It is assumed that it is installed and running. Hereinafter, the unique software will be referred to as 'AdDesk', which will be described later. The AdDesk may be downloaded and installed through the server 100 if desired by the user, or the user may be purchased and installed through a separate computer-readable recording medium such as a diskette or a CD ROM including the AdDesk. In addition, the AdDesk may be operated on the web server 100 to remotely control the user computer. In the following description, it is assumed that AdDesk is installed and running on the user's computer.

Referring back to FIG. 2, the user confirmation step 11 is performed through a user login through the user computer 200. The login procedure may use a conventional method for inputting a user's ID and password. When the user is confirmed, the push server 140 of the web server 100 pushes the ilovesoft.htm files stored in the advertisement information storing means 110 to the user computer. Since AdDesk is running on the user's computer 200, the active desktop of Windows is activated, and when the ilovesoft.htm files are downloaded after connecting with the web server 100, the user's desktop is automatically set as the desktop of the user's computer. . A detailed description of the process of setting the pushed ilovesoft.htm files as the desktop of the user computer and replacing the desktop will be described later.

Next, in a suitable embodiment according to the present invention, the web server 100 monitors the ilovesoft.htm file pushed to the user computer 200 and the web page desktop replacement time preset in AdDesk installed on the user computer. And counter means 151 for synchronization. One of the roles of the counter means 151 is to identify the time when the user manually adjusts the background change time, and synchronize the time with the push time of the push server 140 (step '116 of FIG. 2). '). If the wallpaper replacement time is too fast, the user is inconvenient, and if it is set too slow, the advertisement effect is reduced, so it is appropriate to limit the appropriate time, for example, about 3 to 7 seconds.

Preferably, the counter means 151 may be executed on the user computer 200 to transmit the user's desktop replacement time change information to the control means 150 of the server 100.

In addition, the server 100 may push all of the plurality of ilovesoft.htm files stored in the advertisement information storing means 110 to the user computer 200, or when the user of the authenticated user initially installs AdDesk or the computer. The user preference management means 121 for collecting, storing, and managing a file type to be downloaded during use is set, and the selection means 122 for selecting the advertiser corresponding to the user's preference is further included. In addition, the control means 150 may push the ilovesoft.htm file within the limited range.

The web server 100 grasps the entire ilovesoft.htm file information pushed to each user computer and the ilovesoft.htm file currently set on the desktop (113), selects and pushes the ilovesoft.htm file to push (114). When the user clicks on the webpage displayed on the desktop (115), the corresponding advertisement is stored in the database and recorded in the user's point database, and the record of the advertiser and the user is stored. When the web browser is driven on the forwarding of the advertiser's web page (117). Through such a record, the user can accurately determine the amount of advertisement viewing and the number of clicks on the advertisement, and thus can be used as a basis for giving the user a predetermined amount of prizes or prizes, and provide the advertiser with the actual amount of advertisement.

Next, referring to FIG. 3, an operation of the user computer 200 is illustrated in a flowchart. First, operation of the user's computer is started 310. When the computer is booted, the aforementioned AdDesk program is driven (311). If the AdDesk program is not yet installed on the user's computer 200, as described above, the user can download and install the web server 100 after accessing it, or a computer-readable recording medium such as a separately purchased CD or floppy diskette. Install it on your computer.

When the AdDesk is driven, a login procedure 312 is performed to confirm a user. Since the confirmation procedure is performed by inputting a conventional ID and password as described above, a detailed description thereof will be omitted. When the user is identified through the user database of the server 100, if the active desktop function of the window is not activated, the user is automatically activated (313).

Then, after confirming that the user through the user information according to the user information transmission step 315 described in the operation of the web server 100, and set the ilovesoft.htm file downloaded from the web server 100 as a wallpaper Subsequently, the replaced new ilovesoft.htm file is continuously downloaded (317) while replacing it every predetermined time interval according to the time set by the counter means 151 or the user's manual operation described above (316).

Suitably, the user computer 200 backs up the ilovesoft.htm file downloaded from the server 100 before replacing it with a new ilovesoft.htm file so that the user's computer 200 may be offline even when the network connection is released. Allow the screen to be constantly replaced.

In addition, the ilovesoft.htm file downloaded from the web server 100 is stored, and the desktop replacement can be executed even when the user is offline, and the ilovesoft.htm file information stored when connected to the web server 100 is transmitted. It is desirable to be able to easily identify the updated file of the corresponding ilovesoft.htm file in the web server (100).

On the other hand, when the user clicks on the web page displayed on the desktop (318), the embedded web browser is driven to access the web page clicked by the user to perform normal Internet operations.

In a suitable embodiment according to the present invention, the web browser may be driven to display a separate advertisement such as a banner, text, sound, or video for a short time before the website is displayed on the screen.

The role and function of AdDesk running on the user computer 200 will now be described in detail.

As described above, the file for the desktop that is pushed from the web server 100 to the user computer is a ilovesoft.htm file stored in HTML format. Therefore, you can set this file as wallpaper using the desktop feature of Windows 98.

In a suitable embodiment according to the present invention, the AdDesk utilizes the IActiveDesktop interface of shell32.dll, a Windows system file, to set the downloaded ilovesoft.htm file as the desktop, and newly downloaded ilovesoft.htm every predetermined time interval. Replace with a file. A schematic diagram of the execution process of AdDesk is shown in FIG. 5.

In FIG. 5, the setting of the downloaded ilovesoft.htm file as a wallpaper is described as a SetWallpaper method, and the replacing of the set wallpaper at predetermined time intervals is described as an ApplyChanges (AD_APPLY_ALL) method.

In a suitable embodiment according to the present invention, the SetWallpaper method is configured to change the HKEY_CURRENT_USER / SOFTWARE / Microsoft / Windows / CurrentVersion / Explorer / ShellState item in the Windows 98 registry to the active desktop setting, and then set HKEY_CURRENT_USER / SOFTWARE / Microsoft / InternetExplorer / Desktop This is done by changing the entry / General / Wallpaper.

Through this setting, the ilovesoft.htm file downloaded from the server 100 to the user computer 200, that is, the entire advertiser's homepage is displayed as the desktop, and the user executes the advertisement as if the web browser was executed. You look at your monitor as if you were connected to the home page. Of course, since it is set as the desktop, various icons and the like arranged on the user's computer monitor are displayed as it is.

Next, referring to the ApplyChanges (AD_APPLY_ALL) method, in a suitable embodiment according to the present invention, the AdDesk utilizes the IActiveDesktop interface of shell32.dll, a Windows system file.

The IActiveDesktop interface implemented by AdDesk according to the present invention is attached to the present specification as an appendix. According to the present invention, the IActiveDesktop interface may be implemented in Windows 95/98 or Windows NT / 2000 in which Internet Explorer 4.0 or higher is supported. In this way, the set wallpaper can be replaced every predetermined time interval, thereby making it an effective advertising method for the user.

The contents described so far are examples for helping the understanding of the present invention, and the present invention is not limited thereto. Accordingly, it will be apparent to one skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the appended claims.

For example, if ilovesoft.htm stored in the advertisement storage means stores sub-ilovesoft.htm for some of the main links among the pages linked to the advertiser's homepage, and the user clicks the link displayed on the desktop, Instead of running the web browser right away, you can set the sub-ilovesoft.htm as your desktop once again to allow users to do some sort of web page search.

In addition, the advertisement effect may be enhanced by changing not only the desktop but also the window start, end screen, or screen save screen.

In addition, the web server 100 may not push an advertisement screen that is not a simple homepage, but may push other screens or videos desired by the user, and may implement this as a desktop of the user's computer.

In addition, in the desktop replacement advertising method according to the present invention, various advertising techniques through the Internet, for example, the user is paid a price differentially depending on the time the user saw the advertisement, the number of clicks on the desktop or the number of downloaded web files, etc. Combining well-known advertising methods, such as payment, can increase the user satisfaction and can also expect better advertising effects.

Using the advertising method through the desktop replacement service system according to the present invention, to provide the user with the effect as if the desktop is connected to the advertiser's homepage by running a web browser, the link listed on the desktop directly The user can directly access the web page with the desired information by clicking to shorten the connection time. For the advertiser, the Windows Active Stop function is always activated while the user's computer is connected to the web server 100. Ads can be guaranteed to last for a certain amount of advertising.
