Therefore, the watermarking image generating system 100 receives the coupon information to be provided to the coupon client 110 to receive the watermarking image and the coupon client 110 personal information from the watermarking coupon providing server 105 (415). ). The personal information of the provided coupon client 110 is watermarked on the watermarking image in the step of generating the watermarking image by the watermarking image generating system 100.

On the other hand, if the watermarking coupon providing server 105 cannot provide the personal information of the coupon client 110 at the step of requesting the watermarking image generation (420), the watermarking image generating system 100 targets an unspecified number. A watermarking image can be generated. Therefore, the watermarking image generating system 100 receives only coupon information necessary for generating a watermarking image from the watermarking coupon providing server 105 (425). Of course, in such a case, the personal information of the watermarking coupon providing server 105 is not included in the watermarking image in the step of generating the watermarking image by the watermarking image generating system 100.

When the coupon generation information to be included in the watermarking image is transferred to the watermarking image generation system 100 through the above process, the watermarking image generation system 100 receives the coupon generation information directly processed from the coupon information among the transferred information. It is determined whether to include in the watermarking image or to include coupon generation information obtained by processing the location information in which the coupon information is stored in the watermarking image (430).

If the watermarking image generation system 100 does not directly include coupon generation information in the watermarking image (435), the watermarking image generation system 100 generates a coupon delivered from the watermarking coupon providing server 105. After storing the information in a storage space on the wired or wireless Internet accessible by the wireless terminal of the coupon client 110 (440), the water processing information of the location information on the wired and wireless Internet where the coupon generation information is stored watermarked A marking image is generated (445). The location information on the coupon generation information watermarked on the watermarking image through the above process is used as reference information for the wireless terminal to access the coupon information stored on the wired / wireless internet.

On the other hand, if the watermarking image generation system 100 wants to generate a watermarking image including coupon generation information directly processed coupon information (450), the watermarking image generation system 100 is based on personalized coupon generation information The wireless terminal of the coupon client 110 obtains the wireless coupon presented from the coupon generation information watermarked in the watermarking image by referring to the included wireless terminal information or the wireless terminal information obtained from the mobile communication system 125. It is checked whether it can be generated (455).

For example, not all types of wireless terminals on the market can generate the wireless coupon presented by the present invention. If the wireless coupon proposed by the present invention is a wireless coupon in the form of a barcode as in the embodiment of the present invention, almost all wireless terminals on the market can generate the wireless coupon from the watermarking image. However, if the wireless coupon proposed by the present invention is a wireless coupon in the form of a sound or a wireless coupon that is not standardized, not all wireless terminals in the market can generate a wireless coupon. Accordingly, the watermarking image generation system 100 may directly generate the wireless coupon according to the characteristics of the wireless coupon and the penetration rate of the wireless terminal supporting the wireless coupon.

If the wireless terminal of the coupon client 110 can generate the wireless coupon proposed by the present invention from the watermarking image (460), the watermarking image generation system 100 from the watermarking coupon providing server 105 The watermarking image is generated by directly processing the provided coupon generation information (465).

On the other hand, the wireless terminal of the coupon client 110 can not generate a wireless coupon presented by the present invention from the watermarking image, or the wireless terminal of the coupon client 110 to be used by the policy of the watermarking image generating system 100 If the coupon is generated directly (470), the watermarking image generation system 100 processes the coupon generation information provided from the watermarking coupon providing server 105 to generate a wireless coupon that can be used in the wireless terminal of the coupon client 110 In operation 480, the wireless coupon generated as described above is stored in the coupon D / B 305 mounted in the wireless coupon server 300 on the wired or wireless Internet accessible by the wireless terminal of the coupon client 110 (480). . In operation 485, the wireless terminal of the coupon client 110 generates a watermarking image by processing location information on the wired / wireless internet that can be accessed through the wired / wireless internet.

The watermarking image generated through the above process is transferred to the watermarking coupon providing server 105 providing a coupon providing screen to the coupon client 110 (490), and the watermarking coupon providing server 105 is The watermarked image transmitted as described above is output to the coupon client 110 through the coupon providing screen of the coupon client 110 (495).

FIG. 5 recognizes the watermarking image output on the coupon providing screen through a digital camera mounted in the wireless terminal, and displays the coupon generation information included in the watermarking image through the watermarking image coupon agent. This is a simple flow chart for generating and storing wireless coupons that can be interpreted and used in stores on and offline.

According to the present invention, after the watermarking image coupon agent mounted on the wireless terminal generates the wireless coupon, a certain time difference may be required until the step of using the wireless coupon. Therefore, the wireless coupon generated by the watermarking image coupon agent is stored in a storage space on the wireless terminal and the wired / wireless internet. That is, when the wireless coupon generated by the watermarking image coupon agent may be stored in the wireless terminal, and there is not enough wireless terminal storage space or when the wireless coupon is to be stored in the wireless coupon server 300 by policy. The wireless coupon generated by the watermarking image coupon agent is a coupon D / B of the wireless coupon server 300 linked with the wired / wireless internet and the mobile communication system 125 accessible by the wireless terminal of the coupon client 110. Stored at 305.

Of course, if the watermarking image generation system 100 previously generated the wireless coupon in the step of generating the watermarking image, the wireless coupon is a wireless terminal by downloading the wireless coupon in the step of generating the wireless coupon by the watermarking image coupon agent It may be stored internally, or may be stored and used as it is in the coupon D / B 305 of the wireless coupon server 300.

Hereinafter, the watermarking image output on the coupon providing screen is recognized through a digital camera mounted on the wireless terminal through FIG. 5, and the watermarking image coupon agent interprets the watermarked image included in the recognized watermarking image. The process of generating and storing wireless coupons that can be used in stores on and offline will be briefly described. 5 is a brief description of a process of selecting and processing a specific method from the above-described various methods, and the watermarking image coupon processing method proposed by the present invention includes two or more of the various methods described above. Includes all combined and combined methods.

The watermarking coupon providing server 105 displays the watermarking image output on the coupon providing screen included in the web browser or banner advertisement of the coupon client 110 through the digital camera mounted on the wireless terminal. When photographing (500), the watermarked image photographed as described above is temporarily stored in the wireless terminal, and the watermarking image coupon agent mounted on the wireless terminal confirms the validity of the watermarked image (505).

In the above process, the validity checking process of the watermarking image presented by the present invention is to confirm whether the image image information recognized by the digital camera mounted on the wireless terminal takes the form of the watermarking image proposed by the present invention. will be. That is, the watermarking information suggested by the present invention is included in the image image photographed and recognized by the digital camera, or the watermarking information is not included at all, or copyright information other than the watermarking information suggested by the present invention. This is to check whether the image includes watermarking information.

If the watermarking image image information input and stored in the wireless terminal through the process is not valid (510), the watermarking image coupon agent deletes the image image information (515), and then the watermarking image through the digital camera. Take a picture again and repeat the process of temporarily storing in the digital storage medium inside the wireless terminal.

On the other hand, if the watermarking image input as described above satisfies the condition as the watermarking image proposed by the present invention and the validity is confirmed (520), the watermarking image coupon agent interprets the watermarking image captured and input as described above. By checking whether the coupon generation information can be extracted according to the method of the present invention (525). That is, even if the watermarking image includes the coupon generation information presented by the present invention, it is determined whether the coupon generation information can be accurately extracted due to distortion or damage of the monitor screen of the coupon client side. In particular, the above process includes checking whether coupon generation information can be extracted when a watermarking image is provided through a printing medium such as paper rather than a monitor screen.

If the watermarking image coupon agent cannot extract coupon generation information from the watermarking image according to the method of the present invention (530), after the watermarking image coupon agent deletes the image image information (515), The process of taking a watermarked image through a digital camera and temporarily storing the watermarked image in a digital storage medium inside the wireless terminal is repeated.

On the other hand, if the watermarking image can extract the coupon generation information according to the method proposed by the present invention through the above process (535), the watermarking image coupon agent to generate the watermarked image to generate the wireless coupon proposed by the present invention The generation system 100 extracts coupon generation information included by watermarking the watermarking image (540).

When the coupon generation information included in the watermarking image generation system 100 by watermarking the watermarking image is extracted through the above process, the watermarking image coupon agent is configured to generate a watermarking image generation system from the extracted coupon generation information. In operation 545, the wireless coupon is generated according to the characteristic of the coupon generation information included through the process of FIG.

In the present invention, the wireless terminal recognizes the watermarking image of the coupon providing screen through the digital camera and generates the wireless coupon through the watermarking image coupon agent, the watermarking image generating system 100 through the process of Figure 4 Depends on how this watermarking image is generated.

For example, if the watermarking image generating system 100 generates a watermarking image including personal information such as member information, the watermarking image coupon agent mounted on the wireless terminal may validate the watermarking image through the corresponding member information. Check and generate a wireless coupon including personal information. Of course, even when the watermarking image generating system 100 generates a watermarking image without including the member information, the watermarking image coupon agent mounted on the wireless terminal may be an IC chip or a mobile communication system 125 mounted on the wireless terminal. The wireless coupon including personal information of the coupon client 110 may be generated through the wireless terminal subscriber information obtained from the wireless terminal subscriber information.

In addition, for example, if the watermarking image generating system 100 has generated a watermarking image including coupon generation information that directly processes the coupon information, the watermarking image coupon agent mounted on the wireless terminal may be configured from the watermarking image. The wireless coupon may be generated through the obtained coupon generation information. On the other hand, if the watermarking image generating system 100 generates a watermarking image including location information in which coupon generation information is stored, the watermarking image coupon agent mounted on the wireless terminal is located at the coupon generation information position on the wired / wireless Internet. After the access, the coupon information may be obtained to generate a wireless coupon.

In addition, for example, the watermarking image generating system 100 previously generates a wireless coupon that can be used in the wireless terminal through the coupon generation information, stores the coupon in the coupon D / B 305 of the wireless coupon server 300, and the corresponding position. If the information is included in the watermarking image, the watermarking image coupon agent mounted on the wireless terminal may download and use the wireless coupon in the step of using the wireless coupon.

When the wireless coupon proposed by the present invention is generated through the above process, the watermarking image coupon agent determines a location to store the wireless coupon (550).

If the watermarking image coupon agent determines to store the generated wireless coupon inside the wireless terminal (555), the watermarking image coupon agent stores the wireless coupon generated through the process in a storage space inside the wireless terminal. (560).

On the contrary, if the watermarking image coupon agent determines to store the generated wireless coupon in the coupon D / B 305 of the wireless coupon server 300 other than the wireless terminal (565), the generated wireless coupon is the coupon client. It is transmitted to the wireless coupon server 300 that is linked to the wired and wireless Internet and the mobile communication system 125 accessible by the wireless terminal of 110 and stored in the coupon D / B 305 (570), watermarked image The coupon agent generates wireless coupon location information of the wired / wireless internet and the mobile communication system 125 in which the wireless coupon is stored and stores it in the wireless terminal.

As described above, when the wireless coupon is stored in the wireless coupon server 300 interworking with the wireless terminal and the wired / wireless Internet or the mobile communication system 125 as described above, the watermarking image coupon agent may output the wireless coupon immediately. An output menu is generated (575).

6 is a simple flowchart illustrating a step of outputting a wireless coupon generated and stored by a watermarking image coupon agent mounted on a wireless terminal of the coupon client 110 to the wireless terminal and using the wireless coupon collection system 120.

Coupon client 110 is generated through the process as shown in Figure 5 and the wireless coupon output menu for using the wireless coupon stored in the wireless coupon server 300, which is interlocked with the wireless terminal inside and wired or wireless Internet or mobile communication system 125 If the corresponding wireless coupon is selected in (600), the watermarking image coupon agent is a wireless coupon server that is linked with the wired or wireless Internet and mobile communication system 125 or whether the wireless coupon selected by the coupon client 110 exists in the wireless terminal It is checked whether the coupon is stored in the coupon D / B 305 (300) (605).

If the wireless coupon selected as described above is stored in the wireless terminal (610), the watermarking image coupon agent extracts the wireless coupon stored in the wireless terminal (615).

On the other hand, if the selected wireless coupon is stored in the wireless coupon server 300 linked with the wired / wireless internet and the mobile communication system 125 (620), the watermarking image coupon agent wireless coupon server 300 corresponding to the selected wireless coupon Extract the wireless coupon location information for the coupon D / B 305 of (625), through the extracted wireless coupon location information to access and use the coupon D / B (305) of the wireless coupon server 300 In operation 630, the wireless coupon is downloaded to the wireless terminal.

The watermarking image coupon agent is extracted from the wireless coupon extracted inside the wireless terminal through the above process, or from the coupon D / B 305 of the wireless coupon server 300 linked to the wired / wireless internet and the mobile communication system 125. In operation 635, the downloaded wireless coupon is output to the wireless terminal of the coupon client 110.

When the wireless coupon extracted from the watermarking image is output to the wireless terminal as described above, the coupon client 110 satisfies the condition for using the wireless coupon. Accordingly, the coupon client 110 transmits the coupon information output to the wireless terminal to the wireless coupon collection system 120, the wireless coupon collection system 120 generates the watermarked image through the network the coupon information delivered as described above The system 100 or the watermarking coupon providing server 105 may be transferred to a coupon issuing agency such as to retrieve the corresponding wireless coupon (640).

According to the present invention, the watermarking image generation system on the wired and wireless Internet generates a watermarking image including the coupon generation information and outputs the watermarking image on the coupon providing screen of the coupon client via the watermarking coupon providing server, and is output on the coupon providing screen.
