Abstract: A service server 100 stores commodity information including an image of a commodity for sale and extracts visual information on the commodity image in a form of image information. The service server 100 receives information on an image displayed on or provided at a webpage of a client 200, extracts visual information in the form of image information, and compares the extracted image information with pre-stored commodity image information. When there is a matching commodity, the service server 100 generates visual data, by which information on the commodity can be identified, and displays the generated visual data above or around the image displayed on the webpage of the client 200. Accordingly, a user can identify commodity image information displayed on the webpage or move to a purchase page during web surfing, thereby easily identifying additional information on an interested commodity during web surfing and purchasing the commodity in real time.
