Hereinafter, an electronic commerce method and system by providing product information of a user according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1, an electronic commerce system by providing product information of a user according to an exemplary embodiment of the present invention has a configuration including a user computer, a network, and a server computer.

Here, the server computer is a computer provided in the company that performs electronic commerce by providing the product information of the user of the present invention.

In addition, the user computer accesses the server computer to provide high quality product information, and after a predetermined period of time (one cycle, one cycle, for example, one day, several days, several weeks, etc.), the user's product information is of good quality. In the case of information, that is, the product information of the lowest price, it is the computer of the person who receives a part of the profit generated by the purchaser.

The server computer and the user computer are connected to each other via the network. User computers connected to the network have an Internet browser (Netscape, Internet Explorer, etc.) capable of displaying web content in the form of HTML, XML, and the like.

On the other hand, the server computer includes a program and a database necessary to realize the electronic commerce method by providing the product information of the user according to the present invention.

Here, the program constitutes a control unit, and the control unit may include a main program that operates the entire program, and a low-cost or high-quality product information (for example, a sale site of a difficult-to-purchase product or a large quantity of products available for sale). Sales program), a selection program for selecting the best product information, a purchaser requesting a purchase from the online or offline business company at the lowest price after a predetermined period of time after the purchaser makes a purchase, and the seller decides according to the purchase request. When the prepayment from the buyer is paid to the seller, the remaining amount is returned to the buyer who applied for the purchase at the lowest price, and the payment program and user pays some of the profits from the purchase to the lowest price information provider. The product information provided by It includes a confirmation program for registering and updating product information after checking in real time whether the information is actually available for purchase.

In addition, the database includes a user database and basic product information, additional product information, past, which stores user ID, password, personal information, reliability, shopping expert status, past information provision, product purchase history, holding amount, payment amount, etc. It includes a product database for storing sales volume, hit products, and the like.

As a result, the server computer includes a control unit and a database and is implemented in the form of a website to a user on a network such as the Internet.

Therefore, if a user accesses the server computer through the user computer, executes a main program, and transmits good product information to the server computer, whether the product information provided by the user by the confirmation program is actually purchaseable information. In the case of the actual product information, the lowest price product information of the user's product information is selected in real time by a selection program, and the lowest price product selected from the product information provided by the user during a predetermined period (1 cycle, 1 cycle). The information can be purchased by the purchase program by the information, and the user who provides the good product information can receive some of the profits generated by the purchaser by the payment program.

Here, when the user provides the information, the operator can register the initial product information without a separate confirmation procedure in the case of the information provider who is commissioned as a shopping expert according to the various competitions or the creditworthiness of the individual, but in the case of the general user, the garbage information ( In order to prevent uncompetitive product information that is not sold, the product information of the product actually purchased in the shopping mall operated by the operator or other shopping malls should be provided only when the initial product information is registered, which is confirmed in real time by a confirmation program. .

Once the product information is registered, it is possible to competitively update the product information without distinguishing between shopping experts and general users.

Therefore, according to the present invention, a new concept of shopping information providing job that can sell high-quality information is created even without a shopping mall directly operated among shopping professionals or general users who can provide product information freely through authentication.

In this series of processes, personal information about the user and the buyer is updated in the user information, and the user is provided with the contents of the product information database including basic product information and additional product information of all products.

At this time, the buyer can purchase the product at the lowest price by applying the purchase to the server computer without directly accessing the online operator computer that the user, that is, the information provider has purchased at the lowest price, based on the product information of the user, Such purchase information is not necessarily provided only to online operators, but also to offline operators in each region, so that products can be sold if they belong to an appropriate price (the same or lower price as the online operators).

In other words, an offline operator who can sell the same type of products at the same price as an online operator who sells the same product at the lowest price obtains a priority for selling the product for the rest of the product except for the product provided to the online operator in return for confirming product information and actual purchase. This is a benefit to local consumers because local offline operators are advantageous in delivery, service, and after-sales service.

Therefore, as shown in Figure 2, according to the electronic commerce system by providing the product information of the user according to an embodiment of the present invention, providing a reliable profit structure to the operator, as well as buyers and users, online operators As beneficial to both business and offline operators, the operator can obtain high-quality product information from the user without additional information search time and manpower, and can receive the purchase price from the buyer in advance without the product, You can get commissions for purchasing products from online and offline operators.

In addition, the user, that is, the information provider may receive a part of the profit generated from the purchase of the buyer according to the product information of the user by providing the operator with the high-quality product information obtained from the online operator rather than the boss.

In addition, if a purchaser applies for a purchase at an amount that is considered suitable for the operator, the purchaser can purchase the product at the price of the user who provided the product information even at a lower price. As it can be purchased, high-quality product information can be obtained, and there is no inconvenience of having to access online operators one by one.

In addition, since the online operators and offline operators can receive the purchase information on the products from the operator, they can sell the products to the buyers, so there is no need to perform separate promotions, promotions, and advertising activities for the products, especially offline operators. Even if you do not build a homepage in cyberspace, you can provide goods and services to buyers in cyberspace and receive the purchase price directly.

Therefore, unlike the traditional purchase method in which an online provider unilaterally presents a price and the buyer must follow it, the buyer does not access the website of another online operator and applies for a purchase with only satisfactory product information. You can buy the lowest priced product by purchasing the product at a price lowered.

In addition, unlike the prior art, in which a lot of time and a lot of manpower were consumed in order to know the lowest price of the same product, a benefit is granted to a user providing high-quality product information, so that high-quality product information is not lost and active transactions can be made.

In addition, since the buyer can purchase the product at the lowest price within a predetermined period of time, the buyer can solve the complaint that the purchase more expensive than other buyers.

In addition, it is possible to sell the product to the buyer at a low cost by reducing the cost of performing various promotional activities, promotions and advertising activities to the online or offline operators.

In particular, the registration and update of the product information is made in real time as if competing, information providers who have won in the product information competition can be as profitable as operating a shopping mall even if you do not operate a separate shopping mall.

On the other hand, as shown in Figure 3, when the electronic commerce method by providing the product information of the user of the present invention in order, the product information database to store the product information transmitted by the user, and the product stored in the product information database Comprising a server computer comprising a selection program for selecting a good product information of the information and a purchase program for purchasing a product according to the selected high quality product information (S1), the user through the computer network Transmitting product information to the product information, storing the transmitted product information in the product information database (S2), and selecting high-quality product information according to the value of the product information stored in the product information database by the selection program. (S3), the purchase program according to the quality information selected by the buyer Steps to buy a product by (S4), comprises a step (S5) to award some of the gains by buying the goods to provide a high-quality product information of the user.

Here, FIG. 4 illustrates a more specific embodiment of performing an electronic commerce by providing a user's product information using a server computer constructed after the server computer configuration step S1.

As shown in FIG. 4, when a user accesses the server computer configured in the step S1 and receives a user confirmation (S11), the main screen of the homepage is displayed as shown in FIG. 9 by the main program. In this case, the user decides whether to provide information (S12), apply for a purchase (S13), or simply search for information (S14).

In this case, hit products are displayed on the main screen of the homepage, and these hit products are displayed in the order in which the most purchase applications have been received so far, and are configured to motivate the information provider.

Subsequently, when the user wants to provide the information, the basic product information as shown in FIG. 6, such as a manufacturer, a product name (model name), a product picture, a product video, etc., of the product previously stored in the product information database of the server computer, is displayed. It is displayed (S15).

In this case, it is preferable that the operator provides the characteristics of the product, the description of the use, and the number of sales in advance, and the reason for displaying the number of sales of the products is to display the number of actually sold, so that the user can obtain the amount of profit allowance that can be obtained when the user is an owner. If the earnings allowance is large, it can be a powerful motivation to actively seek cheaper information.

In addition, the greater the number of sold (the number applied for purchase), the higher the possibility that the online operators themselves will provide product information at a lower price.

Subsequently, in addition to the basic product information, the user adds product features, instructions for use, trade names of shopping malls, selling shopping mall addresses, selling prices, sales numbers, product information provider names, usage periods, and reasons for recommendation to the product information database. As shown in FIG. 7 and FIG. 11, actual product information that can be purchased is provided (S16).

Subsequently, it is determined whether the product information provided from the user is the lowest price (S17), and if the lowest price, a message as shown in FIG. 12A may be output, and in the case of registering product information, whether the provided product information is actually purchaseable product information. It is confirmed in real time (S18).

If the product information provided from the user is not the lowest price, a message as shown in FIG. 12B can be outputted. If the product information provided from the use is already registered product information, as shown in FIG. You can output the same message.

At this time, if the user's trust is high or the shopping expert commissioned to the operator, the confirmation procedure can be omitted. Otherwise, in order to prevent garbage information, the product of the user who actually purchased the product must be registered when registering the initial product information. Only information can be updated.

In other words, the confirmation of the product information, the operator performs the procedure to check the product information provided by the user in real time on the wire or computer network, and it is impossible to register the product information or register the product information depending on the authenticity of the product information Message to the user, calculate the personal reliability of this, and register as an information provider according to the calculated personal reliability, or later, it can be achieved by blocking the computer access to the false information provider.

Subsequently, when the product information is actually confirmed as the product information that can be purchased, the user who provided the new product information is recognized as the right holder who can receive the profit, and the product information is updated accordingly (S19).

Subsequently, when a predetermined time, that is, a time when information is available (S20) ends, it is checked whether the provided product information is the lowest (S21), and as shown in FIG. 8, the lowest price among the product information provided by the users. As shown in FIG. 14, a message is output to the user who has provided the lowest price product information selected as a portion, and a portion of the profits from the purchase is awarded (S22), and the fact is stored in the user database to update the user information. (S23).

At this time, it is possible to give users the privilege of providing online payments, giving cyber money or giveaways, giving access to other sites, or providing product information as a shopping expert without a separate confirmation procedure. .

On the other hand, if the user wants to purchase, the buyer selects the product (S24), click on the purchase in the screen as shown in Figure 13 to apply for a purchase (S25), when the information providing time is over ( S26), irrespective of the purchase application time, the product can be purchased at the lowest price at the time when the information providing time ends (S27).

In other words, when the conventional buyer thought that the product was bought cheaply, and found that another store sells the same kind of product at a lower price, it is possible to solve the dissatisfaction.

Such a product purchase, first, when the product information provided by the buyer, which is considered to be a good condition, is applied for a purchase, and after one cycle, the product price drops further, the cash is returned or the settlement amount is corrected. You can earn cyber money by paying or giving points.

This fact is also stored in the user database so that the user information is updated (S28).

On the other hand, if the user wants a simple information search, as well as the basic product information provided by the operator, as well as additional product information provided by other users, that is, information providers as shown in Figure 10, it is possible to search for general product information In operation S29, the hit product information S30 in which a predetermined amount or more is sold during the past period may be searched.

Subsequently, when the user wants to purchase (S31), select a product (S24), apply for a purchase (S25), after the information providing time is finished (S26) a series of products to purchase the lowest price (S27) The procedure can be repeated.

On the other hand, as shown in Figure 5, the step of purchasing the product at the lowest price (S27) is made of the following process. The operator excludes one purchase information to be provided to the online operator, and provides the remaining purchase information to offline operators scattered in each region (S271), and the offline operator purchases the item for sale by the user in one click. It is possible to supply the goods to the users who applied for (S272), if the supply is insufficient (S273), the online provider provides the purchase information of the goods that were not supplied to the offline operators (S274), It is possible to supply the goods to the users who applied for a purchase (S275).

In other words, when the lowest price is determined at the final price, the online provider is allowed to sell only one product requested by the buyer to the online operator in exchange for the product information registration. The remaining product information is limited to the offline operator's computer. Make sure to display for a period of time (eg 1 hour).

At this time, the offline operator selects a product that can be sold by only one-click among the displayed purchase information, and the operator provides more detailed information of the product selected by the offline operator through the server computer to make the sale.

After that, a number of off-line operators give up products that can be sold by the on-line operators.

If the inventory is not available due to lack of inventory, it is a factor that can facilitate the purchase application of the buyer by supplying the products in the order of purchase application.
