Method for ensuring safety of buyer and seller in network transaction

Technical Field

The invention relates to a network transaction method, in particular to a network transaction method which can ensure that 'virtual commodities are not maliciously used, or software registration codes or point card verification passwords are not sold by more than one object, or a seller preempts the buyer before registering before the buyer is sold to the buyer', and both the buyer and the seller can respectively and really obtain the virtual commodities and money.

Background

With the advancement of network communication technology and the vigorous development of electronic commerce, more and more enterprises and individuals can choose to trade commodities through a network platform, and particularly for individual consumers, the consumers can buy commodities around the world without being limited by regions and time only by pressing keys of a computer or a mobile phone, so that the system has extremely high convenience and can greatly expand the field of selling and increase the trade opportunities of global market marketing.

According to taiwan electronic commerce method of 96 years and the innovative electronic commerce model research report of the basic environment construction plan, the current forms of network transactions can be largely divided into:

(1) Business-to-Business transactions (Business to Business, abbreviated as B2B): the system refers to the cooperative operation among enterprises, and transactors such as electronic order purchase, bid placing, customer service, technical support and the like are performed among the enterprises in an electronic mode through the Internet, an Intranet or an Extranet;

(2) business-to-individual transactions (Businessto Customer, short B2C): the system provides goods, services or information for the consumers through the Internet for enterprises, and is also network consumption realized by individuals through a network shopping platform, and comprises applications of online shopping, securities ordering, online databases and the like;

(3) person-to-person transaction (Customer to Customer, C2C for short): the network service provider provides an electronic commerce platform and a transaction program, allows two parties (mainly individual users) engaged in trade and sale transaction to independently bid or negotiate price on the platform in a network transaction mode, and spontaneous commodity transaction behaviors among consumers include a manufacturer network direct marketing pipeline, a network auction platform, a general personal auction website or a second-hand flea market and the like;

(4) person-to-Business transactions (Customer to Business, C2B for short): the buyer group shopping power is integrated to negotiate with the seller to achieve the group price killing purpose, and the information provided by the consumer is shared with other consumers, such as: product price comparison mechanisms such as a co-purchase platform and a group purchase website.

As mentioned above, for general consumers, the most commonly used network transactions are two types, i.e., B2C and C2C, but as more and more consumers are willing to go online for shopping, consumption disputes of network transactions are caused and frequently occur. Because the average consumption amount of the network transaction is not high, the time and money consumed for litigation obviously greatly exceed the consumption amount after a consumption dispute event occurs, and the network transaction is not beneficial to consumers. Therefore, to avoid the foregoing situation, most of the existing network transaction platforms tend to maintain the rights of the consumers (i.e. buyers), such as: and paying the money to the merchant (namely, the seller) by the third party transaction platform after the seven-day appreciation period or after the consumer confirms that the goods are received. Also, with the prevalence of online games, many game commodities (e.g. virtual game, point cards) will be sold in online transaction manner, for example, after the introduction of the prior online transaction system and transaction method for providing game commodities, please refer to fig. 1, the online transaction system 1 includes a first terminal device 11, a second terminal device 12 and a third-party server 13, wherein the third-party server 13 is provided with a transaction platform (e.g. treasure transaction 8591 website) for a user to view commodity contents on the transaction platform through the displays of the first terminal device 11 and the second terminal device 12, and the third-party server 13 is provided with an account data 131 and a money data 132, the account data 131 includes a plurality of accounts, the money data 132 includes a plurality of money items, and each account corresponds to one money item, in particular, each account is an account number that the user registers in advance on the third-party server 13, and the user can perform a value storing procedure in the third-party server 13, so that the registered account number can correspond to the amount of money to be recharged, so as to smoothly perform subsequent transactions.

Referring to fig. 1, when a seller wants to sell a credit card, the seller can transmit a commodity sale information to the third-party server 13 through the first terminal device 11, wherein the commodity sale information includes account information (such as an account name or an identification code representing the account), a name of the credit card and a sale amount of the credit card of the seller, and after the third-party server 13 receives the commodity sale information, the sale information of the credit card is displayed on the transaction platform for others to search for a virtual commodity desired to purchase through the transaction platform, and when a buyer views the contents of the transaction platform through the second terminal device 12 and wants to purchase the credit card, the seller can enable the second terminal device 12 to transmit a commodity purchase information to the third-party server 13 through the transaction platform, wherein the commodity purchase information includes the account of the buyer, The name of the point card and a purchase amount, when the third party server 13 receives the commodity purchase information, it will first determine whether the corresponding money in the buyer's account is enough to pay the purchase amount, if it is enough, the third party server 13 will first deduct the money from the buyer's account to deduct the purchase amount, but will not pay the purchase amount to the seller, but will first freeze the purchase amount, and send a notice to the first terminal device 11, so that the seller knows that the point card is sold, then the seller can mail the point card to the buyer, or directly provide the serial number on the point card to the buyer, when the buyer gets the point card, the seller will transmit a transaction completion information to the third party server 13 through the second terminal device 12, after the third party server 13 receives the transaction completion information, the frozen purchase amount will be added to the money corresponding to the account, thus, the buyer can obtain the commodity of the seller smoothly.

However, referring to fig. 1, the foregoing network transaction method still has some problems, first, for the credit card, once the buyer receives the physical card or the serial number of the credit card, the buyer will usually transmit the transaction completion information directly through the second terminal device 12, so if the seller sells and receives the money, the seller will use the serial number of the credit card on the network immediately, which will make the buyer unable to use the serial number of the credit card. In addition, if the buyer receives the serial number of the physical card or the credit card and is late to transmit the transaction completion information, the seller cannot obtain the money, and further a lot of transaction disputes are derived.

In summary, the conventional third party payment and network transaction method is fundamentally very defective for the buyer or seller and still requires to rely on interpersonal trust for success, so how to design a better network transaction method for the above defects becomes an important issue for the related network business.
