Online shopping has become a very common form of shopping as the Internet is becoming more common and, as a result, advances in electronic payment and security technologies. However, when using such online shopping, consumers cannot directly access and buy goods, so they exchange opinions with other users interested in the goods or refer to the reviews of users who have already purchased the goods. . Therefore, recently, online shopping sites generally provide a bulletin board function so that users can exchange opinions or upload purchase reviews.

Recently, social shopping has become popular as a form of online product sales site. Social shopping is also known as social commerce, in which certain items are sold on the Internet for a limited period of time only at a very low price, but only when a minimum amount predetermined by a site operator is sold. This allows buyers to receive discounts and sellers to enjoy both mass sales and promotions. Eating out tickets, commodity exchange tickets, and service vouchers are usually traded.

Recently, as social network services have proliferated and communication environments such as mobile communication have changed, more advanced social shopping malls have emerged. In the conventional online shopping mall, if the shoppers were recruited through online advertisements, social shopping is characterized by adding the effect of creating tipping points by actively informing the products to be purchased by users who actively use the social network and participating in the purchase together. .

In such social shopping, in order to maximize the effect of tipping point, only one item is sold per day, which leads buyers to respond and cooperate in a short time.

In such social shopping, sales of a certain product are terminated in a short period of time, so users have to make a decision to purchase the product quickly. To this end, users exchange opinions about the product and review reviews of users who have already purchased the product. The role of the bulletin board to share is even more important.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described by an embodiment of a product buyer display method of an online product selling site and an online product selling system therefor.

Example of the web page of the online product sales site according to the display method, and Figure 6 is an example showing the purchase history of the buyer on the web page of the online product selling site according to the buyer display method of the online product selling site according to an embodiment of the present invention It is also.

As illustrated in FIG. 1, an online product selling system according to an embodiment of the present invention exchanges data with a plurality of user terminals 100 to sell a product, and configures an online product selling site in the user terminal 100. It includes a product sales server 200 for transmitting a web page and a database server 210 for storing product-related bulletin board data and user account information, and product purchase history information for each user account.

Here, the user terminal 100 may include a variety of wired / wireless information processing devices such as a desktop computer, a laptop computer, a mobile communication terminal, a tablet computer, and the like.

The product selling server 200 transmits web pages included in the online product selling site to the user terminal 100 at the request of the user terminal 100. In this case, the online product selling site may be a general product selling site or a social shopping site.

In this case, the online product sales site may be configured as a separate web page including an independent bulletin board for each product or service to be sold. That is, as illustrated in FIG. 3, the online product sales site is provided with separate bulletin boards each subordinate to one same product or service. Since a separate bulletin board is provided for each product or service, users can exchange opinions or post product purchase reviews only for the corresponding product or service. In addition, in the online product sales site, one web page may be allocated to one product or service.

That is, for example, as shown in FIG. 4, product information may be displayed at the top of one web page for one product and a bulletin board may be configured at the bottom thereof. Here, the bulletin board displays the registered articles from the user terminal 100 in the order of registration.

In addition, the database server 210 stores information about each user and information about each product, information about the user includes the purchase history of the user, and information about each product is included in the bulletin board Contains post information. Accordingly, the product selling server 200 provides an online product selling service to the user terminal 100 using the data stored in the database server 210.

In particular, in the embodiment of the present invention, the merchandise sales server 200 displays the ID (ID) or nickname, etc. of the user who registered the article, for each article uploaded to such a bulletin board, the uploaded article is Indicate who is registered by. For example, in the web page shown in FIG. 3, when looking at the bulletin board displayed at the bottom, the user ID that registered the post for each post is displayed in the front of the post, and the user ID has a cover with a circular shape filled in red. Optionally attached, such a cover is displayed on the ID of the user who uploaded the post, if the user who registered the post has already purchased a product on which the bulletin board to which the post is registered is already purchased.

In other words, when a post is registered with a specific user ID on a web page bulletin board of a specific product, the product sales server 200 searches for the purchase history of the user who registered the post in the database server 210 and includes the corresponding product in the purchase history. Check whether or not. If the corresponding item is included in the user purchase history, a predetermined mark is displayed together with the user ID. If the corresponding product is not included in the user purchase history, the cover letter is not displayed on the user ID. Here, the cover may be composed of icons having various colors and shapes.

For example, as shown in FIG. 4, when a user having a user ID of "kya03 **" registers a post on a bulletin board that is dependent on a product related to "Enprani", the product sales server 200 has a user ID of " If the user's purchase history of "kya03 **" has a purchase record for "Enprani" cosmetics-related products, and if it is confirmed that there is a purchase record for "Enprani" cosmetics-related products, By displaying a predetermined sign next to the ID "kya03 **", not only the users but also other users can confirm that the user with the ID "kya03 **" is the buyer of the subordinate product. On the other hand, if a user with ID "qnddjskav **" does not have a record of purchasing "Enprani" cosmetics in the purchase history of a user, the user may register a post and set a predetermined name next to the ID "qnddjskav **". You can see that no cover is shown.

A specific user may purchase A product and not B product. As described above, when a user uploads a post to a bulletin board of a web page about A product, the user is displayed in the uploaded post. While the ID is displayed with the buyer's cover, when the user uploads a post on the bulletin board of the web page for the product B, the user's ID is not displayed on the uploaded post. Accordingly, even the posts of the same user may be evaluated differently depending on the purchase of each product.

Here, the 'buyer's cover' is used as a cover indicating that a post about a specific product was made by a person who purchased a specific product, and in this specification, an icon that visually indicates whether or not a buyer has written on each post on a web page. It may also be used as a term to mean an identifier that makes it possible to identify whether each post was made by a buyer when each post is stored in a database.

Referring to the description of the buyer display method of the online product selling site using the online product selling system as described above, as shown in Figure 2, any product being sold on the online product selling site (hereinafter referred to as 'first product') When a new post upload request is received through the user terminal 300 with an account of an arbitrary user (hereinafter, referred to as 'first user') (S100), the merchandise sales server 200 is connected to the database. The server 210 reads the purchase history of the first user newly uploading the post (S110).

Then, it is checked whether the first product to which the bulletin board to which the post is registered is included in the purchase history of the first user (S120). When the first product is included in the purchase history of the first user, the post data received together with the post upload request is included in the buyer cover and stored in the database server 211 (S130). If not included in the purchase history of the user, only the post data received with the post upload request is stored in the database server 210 (S140).

By distinguishing whether each post uploaded to the bulletin board is written by the buyer or not to the buyer through the above method, as shown in FIG. 4, each post of the bulletin board for each product is the author of the post. Buyer markers are displayed which distinguishably indicate whether is a buyer of the product.

In addition, as described above, in addition to the embodiment in which one web page is assigned to one product and the bulletin board displayed on the web page is dependent on only one product, the user who registered the post on the bulletin board indicates whether to purchase the corresponding product. As shown in FIG. 5, when each user wants to register a post on one bulletin board for multiple products, the user who wants to register the post selects one of a plurality of products to find out what products related to the post are. The product sales server 200 can be confirmed.

When the user creates and registers a post, the product sales server 200 searches the database server 210 whether the product selected by the user is included in the purchase history of the user who created the post, and if the user directly If the selected item is included in the user's purchase history, the buyer's cover will be displayed next to the user ID displayed on the post. If the user's selected product is not included in the user's purchase history, the user's ID will be displayed next to the user ID. Do not display buyer signs.

For example, as illustrated in FIG. 5, in order to exchange or transfer a product purchased by a plurality of users, a user who wants to transfer a product on a bulletin board set up to express exchange or transfer of the purchased product. Posts the product, the product sales server 200 allows the user to select a product to be transferred among a plurality of products in the user terminal. A list of products included in the purchase list of the user may be provided to the user terminal to select one of them. When a user selects a product and writes and registers a post, the selected product information and the created post are registered together on the bulletin board. In this case, for example, if a user using the ID "pooh43 **" selects a "Musical Wizards" ticket among a plurality of products as a product to be transferred and registers a post, the database server for the user of the ID "pooh43 **" is registered. After checking whether the purchase record recorded in 210 includes the "musical wizards" ticket, the buyer cover may be displayed together with the ID "pooh43 **" only if it is included. In this case, the user who wants to transfer the product can check whether the user who registered the transfer-related post is the buyer of the actual product, and thus can make a more reliable transaction.

On the other hand, if the user who purchased a particular product cancels the purchase, the product sales server 200 is a bulletin board dependent on one product as shown in Figure 4, or a plurality of products as shown in FIG. The buyer cover can be removed from the user ID that is displayed on the post registered on the bulletin board. Alternatively, the cover, which was indicated by a red icon filled with red in the purchase state, may be changed to a circular icon filled with gray after canceling the purchase.

In addition, when displaying a buyer's cover next to a user ID, the user ID displayed on all posts of the user included in a specific bulletin board, without distinguishing between posts registered by a user who purchased a certain product and posts registered after the product purchase. All may display a buyer cover, or a buyer cover may be added only to a user ID that is displayed in a post registered after a product purchase. That is, when user A registers two posts on a bulletin board included in a web page for a specific product as shown in FIG. 4 and then purchases the corresponding product and registers one more post, the bulletin board of the corresponding web page Of the three posts of the user A registered in, two posts registered before the product purchase do not display the buyer cover, and only one post registered after the product purchase may display the buyer cover. Alternatively, the cover color or shape may be changed to distinguish posts registered before purchase and posts registered after purchase.

In addition, if the user who purchased the product on the bulletin board subordinate to a specific product wants to register a post, the product sales server 200 looks up the purchase history of the user who wants to register the post specific user that the bulletin board depends If it is confirmed that the buyer is a product, whether the user is satisfied or dissatisfied with the purchased product may be selected whether the user is satisfied or dissatisfied. In this case, the buyer cover may be divided into two different signs, and may be displayed to distinguish whether the buyer is satisfied or dissatisfied with the product. In this case, the user who wants to purchase the product can check the satisfaction or dissatisfaction of the users who registered the posts on the bulletin board, so that they can assist in the purchase decision.

Meanwhile, in the embodiment of the present invention, when a request for viewing a bulletin board of a first product is received from an arbitrary user as shown in FIG. 3 (S200), a bulletin board for the first product is provided (S210).

If a user clicks or touches a buyer cover displayed on a post made by the first user in the provided bulletin board (S220), a list of product purchases registered in the user account of the first user is displayed (S230). 1You can check what products you have purchased. Alternatively, when selecting the ID of the author displayed on each post, the purchase history of the user of the selected ID may be displayed. That is, as shown in Figure 6, the product sales server 200, when the user selects the ID of a particular user displayed in the post registered on the bulletin board of the web page, the user of the ID in the online product purchase site You can check the purchase history of the product. For example, when the user selects the ID "sang **" while viewing the bulletin board, a list of the product purchase history of the user corresponding to the selected ID may be displayed. As shown in FIG. 6, the product purchase history of the selected ID user may be displayed as a pop-up window of a separate layer. ID "sang **" It can be seen that a separate pop-up window containing the user's product purchase list is displayed on the existing web page. Of course, even when the user ID displayed on the bulletin board as shown in FIG. 5 is clicked, a pop-up window including a purchase history list as shown in FIG. 6 may be displayed.

In addition, according to an embodiment, the purchase history list of such users may be confirmed only by the logged-in member. When a user who is not logged in clicks on a specific user's ID on the bulletin board, the user may send a guide to log in to check the purchase history list, and the purchase history list may not be exposed.

Each user can choose whether or not to publish his purchase list to other users. To this end, the merchandise sales server 200 may provide a web page including a user interface through which users can select whether to disclose their purchase history to other users. If you do not want to expose your purchase list to other users, you can set your purchase list to be private, and users who set their purchase list to private can log in to the online product sales site and use other users on the bulletin board. Even if you click on the ID of the selected user can not see the list of purchase history. That is, the product sales server 200 selects a specific user ID from the user terminal requesting the web page including the bulletin board to view the purchase history list. If it is confirmed that the user is logged in, the user checks again whether the user has set his or her purchase history list to others, and publishes the purchase history list of other users only when the user is set to publish.

If a specific user sets their purchase list to private and then switches to public later, the user can check the purchase list of other users at the same time as the conversion, but switching to private again is a set time (for example, Only after 24 hours, it is possible to prevent the user from checking the purchase history of another person without exposing his / her purchase list to others.

In addition, the product sales server 200 is not only set the public / private setting of the entire purchase history list from the users, but also to enable the individual / public setting of each of the details included in the purchase history list, A user may provide a select box that allows a user to check his / her purchase history on his account management web page and set whether to disclose each of them. When setting the purchase record of a specific product to be private, even if another user clicks the user's ID, the product set as private in the entire purchase history list may be displayed. However, even in such a case, when a user posts on a bulletin board of a web page about a product which is set as private in his purchase list, the buyer's cover may appear on the user's ID. However, even if a user sets a purchase record for a specific product in his purchase list as private, the purchase record for the specific product of the user is not deleted in the corresponding user account stored in the database server 210, and all the purchase history continues. Can be stored cumulatively.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
