Recently, as the penetration rate of computers and high-speed Internet has increased, electronic commerce using the Internet has been actively performed. In particular, P2P (Peer to Peer) e-commerce system is widely spread due to the advantage that can easily purchase a variety of products, compared to the e-commerce using the Internet shopping mall. P2P is a concept that has been used for a long time in information communication theory and computing structure. It means that a plurality of devices do not have different roles like a client or a server, but have an equal status and exchange data.

The P2P e-commerce system introduces the concept of P2P to e-commerce. Instead of trading products using information stored on the server, a plurality of users have their own information about the product and other users' information about the product. It is a system for searching for a desired product by searching and trading the product through a direct transaction with the user having the information.

As shown, the conventional P2P e-commerce system is composed of a plurality of user terminals (110, 120) and the e-commerce server 130 connected to the Internet. When the first user terminal 110 transmits a keyword regarding a desired product to the e-commerce server 130, the e-commerce server 130 searches for digital content corresponding to the keyword from other user terminals. As a result of the search, when digital content corresponding to the keyword exists in the second user terminal 120, the first user terminal 110 requests the second user terminal 120 to transmit the digital content. The second user terminal 120 transmits the digital content to the first user terminal 110 in response to the request.

If the e-commerce server 130 provides the search results to the first user terminal 110 without a separate authentication procedure, and the digital content is free content that does not require a separate payment, the first user terminal 110 Through the above process, the digital content can be downloaded conveniently. However, when the electronic commerce server 130 requires authentication, the first user terminal 110 should receive the authentication information from the user and transmit it to the electronic commerce server 130. In addition, when the digital content is a paid content, the first user terminal 110 receives payment information such as a credit card number from a user to perform a payment or transmit the payment information to a predetermined payment server.

Therefore, in the case of purchasing digital content using the existing P2P e-commerce system, the user must register to the e-commerce server by inputting personal information and enter the authentication information to log in to the e-commerce server to search for the product. Enter the payment information to pay the price of the desired digital content. As such, since personal information, authentication information, and payment information must be frequently input, there is a risk that personal information is leaked, there is inconvenience in use, and reliability of payment cannot be guaranteed.

Therefore, it would be a meaningful invention if the P2P e-commerce service can be used without inputting personal information, authentication information and payment information. Therefore, in the present specification, in a P2P e-commerce system, a product is located between a user's terminal and the Internet, and in response to the request without transmitting the request to the user terminal when there is a request for authentication information or payment information in a transaction of a product. The present invention proposes a new technology related to an accountless billing processing device that returns authentication information or payment information.

In general, a packet used in data communication has a structure including a header including information about a destination to which a packet is to be transmitted and information about data included in the packet, a Taylor including error information, and a data to be transmitted. However, the term "packet" in the present invention is used as a term encompassing all data that can be transmitted through the Internet, a network, or a data transmission channel regardless of an internal structure.

2 is a diagram illustrating a network configuration of a P2P e-commerce system using an accountless billing processing device according to an embodiment of the present invention.

In the P2P e-commerce system using an accountless billing processing apparatus according to an embodiment of the present invention, a plurality of user terminals 210 and 230 are connected to the e-commerce server through the Internet, as in the conventional P2P e-commerce system illustrated in FIG. 1. It has a configuration that is connected to (250). However, the non-account billing processing devices 220 and 240 are located between the respective user terminals 210 and 230 and the Internet, and the user terminals 210 and 230 relay packets sent and received through the Internet.

The first user terminal 210 and the second user terminal 230 are user terminals in which a P2P e-commerce client program is installed, and allow a user to trade a product using the P2P e-commerce client program. The user terminal may include any terminal that can be connected to the Internet such as a personal computer, a PDA, a mobile phone, and a digital TV.

The first non-accounting processing unit 220 and the second non-accounting processing unit 240 are respectively connected between the first user terminal 210 and the Internet and between the second user terminal 230 and the Internet, respectively. The user terminal 210 and the second user terminal 230 relay packets transmitted and received through the Internet. In the process of relaying the packet, the first non-accounting processing unit 220 and the second non-accounting processing unit 240 transmit the packet to the user terminal when the relayed packet is a packet requiring authentication or payment. Without passing, the authentication information is returned, or payment is made and information about the payment is returned.

When the e-commerce server 250 receives a search request from the first user terminal 210 as a server for mediating P2P e-commerce, the e-commerce server 250 searches for digital content stored in another user terminal to obtain a search result corresponding to the search request.

Figure 3 is a block diagram showing the internal configuration of the accountless billing processing apparatus according to an embodiment of the present invention. As shown in the figure, the accountless processing apparatus 302 includes a terminal interface 310, a network interface 320 and the relay unit 330, the payment unit 340, the media reader 350, It may further include a class identification unit 360, access restriction unit 370 and the activation unit 380. Hereinafter, the function of each component will be described in detail.

The terminal interface 310 is connected to the user terminal 301 where the P2P e-commerce client program is installed to exchange packets. The P2P e-commerce client program is installed in the user terminal 301 to allow a user to use P2P e-commerce, and provides functions such as content search, content information check, and content download. The user terminal 301 may be any terminal provided that the P2P e-commerce client program can be installed and connected to the Internet.

The network interface unit 320 is connected to a predetermined remote system through the Internet 303 to exchange packets. The remote system may be another user's accountless processing device or a predetermined e-commerce server, and may also include any system capable of connecting to the Internet 303. Since the accountless processing device of the present invention is located between the user terminal 301 and the Internet 303, the network interface unit 320 connected to the Internet can be accessed by the user terminal 301 through the Internet. It can be connected to a remote system.

The relay unit 330 transmits the packet received from the remote system through the Internet 303 in the network interface unit 320 to the user terminal 301 through the terminal interface unit 310, and in the terminal interface unit 310. The packet received from the user terminal 301 is transmitted to the internet through the network interface 320. Therefore, in general, packets transmitted and received by the user terminal 301 through the Internet are relayed without a separate processing procedure.

However, if the packet received from the remote system via the Internet 303 in the network interface 320 is a packet for requesting user authentication information for the user of the user terminal 301, the relay unit 330 may be configured to transmit the packet to the packet. In response, the user authentication information is transmitted to the remote system through the network interface unit 320. Accordingly, the user terminal 301 may use a remote system that requires user authentication information without inputting user authentication information. In addition, the relay unit 330 may not transmit the packet to the user terminal 301, and the user terminal 301 may conveniently use a remote system without checking whether there is a request for user authentication information. The user authentication information may be transmitted to the user terminal 301 in advance, stored in a predetermined storage device, and used.

For example, in a P2P e-commerce system, when a user terminal wants to search for content existing in another user terminal, a search keyword may be requested by inputting a search keyword to a predetermined e-commerce server. In the case of a server requiring user authentication, a packet for requesting user authentication information may be transmitted to the user terminal. In a conventional P2P e-commerce system, a user terminal receives a packet requesting user authentication information, requests a user to input user authentication information, receives user authentication information from a user, and sends the user authentication information to the e-commerce server. Had to be sent to. However, when using the accountless processing device according to the present invention, in response to the user authentication information request packet, the relay unit 330 of the accountless processing device transmits the user authentication information to the e-commerce server, the user authentication Since the information request packet is not transmitted to the user terminal, the user can conveniently use the P2P e-commerce system without checking whether the user authentication information is requested.

In addition, when the packet received from the user terminal 301 through the terminal interface unit 310 is a packet that requires user authentication information, the relay unit 330 may add user authentication information to the packet to add a network interface unit ( 320 may be transmitted to the Internet 303. Therefore, even if the remote system does not request user authentication information, when the user authentication information is required, a packet to which the user authentication information is added may be automatically transmitted to the remote system through the Internet 303. Therefore, since the user authentication information request packet and the user authentication information packet do not need to be transmitted and received separately, the amount of packets sent and received between the remote system can be reduced, and the user using the user terminal 301 can use the separate user authentication information. The advantage is that the remote system can be used conveniently without input.

In addition, the relay unit 330 decrypts the packet when the packet received from the remote system through the network interface unit 320 is encrypted by the remote system and transmitted to the user terminal through the terminal interface unit 310. Forward to 301. Alternatively, the packet received from the user terminal 301 through the terminal interface 310 may be encrypted and transmitted to the remote system through the network interface 320. Therefore, when receiving content from another user's accountless processing device, the relay unit of another user's accountless processing device encrypts and transmits a packet including all or part of the content, and relay unit 330. In the present invention, the packet may be decoded and transmitted to the user terminal 301. Therefore, there is an effect that can maintain the security of the content without installing a separate encryption and decryption module.

In addition, the relay unit 330 may check whether the packet received through the network interface unit 320 is a safe packet and allow the packet only when the packet is a safe packet. In order to check whether the received packet is a secure packet, a list of untrusted systems may be stored in a predetermined storage device, and it may be checked whether the packet is transmitted from a system included in the list. In addition, by identifying which port the packet is received by the user terminal 301, the packet may be identified as a secure packet. The relay unit 330 may add and transmit predetermined data, which means an unauthorized packet, to a packet that has not been identified as a secure packet, and may ignore the unauthorized packet in the P2P e-commerce client program installed in the user terminal 301. Can be. Therefore, it is possible to obtain the same security effect as installing a firewall by identifying and filtering packets that are dangerous for security.

The payment unit 340 performs payment corresponding to the payment request when the packet received by the network interface unit 320 is a packet related to the payment request. In the case of performing the payment, when user authentication information is required, payment may be performed using user authentication information recorded in a predetermined storage device without requiring user authentication information to the user terminal 301.

In addition, the payment unit 340 may transmit the information on the payment made to a predetermined e-commerce server, the e-commerce server relates to the list of beneficiaries to be compensated in association with the content corresponding to the payment request and the revenue ratio After storing the information, the beneficiary may be compensated according to the profit ratio based on the payment information. The beneficiary may be a person who owns the copyright of the content or a person who has the right to distribute the content, and has a certain profit ratio according to the right of the content. As described above, when the payment is made, the amount paid according to a predetermined profit ratio is distributed to the beneficiaries. Therefore, those who have a right to the content more actively use the P2P e-commerce system using the accountless processing apparatus of the present invention. Through this, it is possible to induce content distribution.

The media reader 350 reads a portable storage medium that stores the user's charge amount information. In order to easily perform a payment without inputting additional payment information in the payment unit 340, a payment means is required. The media reader 350 reads a portable storage medium in which an amount is charged in advance, thereby allowing a payment amount to be subtracted. Provide a payment method. The portable storage medium may be a card including an IC chip, a card on which a bar code is recorded, or a card including a magnetic bar. The media reader 350 may use an RFID reader, a barcode reader, or a magnetic bar reader according to the type of the portable storage medium. It may include.

In addition, the user authentication information may be stored in the portable storage medium. In this case, the media reader 350 may be portable when necessary, without having to store user authentication information by having a separate storage device inside the accountless processing device 302. The user authentication information stored in the storage medium can be read and used.

The rating identifier 360 identifies the rating of the content associated with the packet received through the network interface 320. Among the digital contents, there are contents whose users can be used according to age. Accordingly, when a packet corresponding to the content is received, the class of the content may be identified to determine whether to forward the packet according to the class. In order to identify the grade of the content, the system for transmitting the packet may add data indicating the grade of the content to the packet and transmit the data so that the grade identifying unit 360 may check the data, and the predetermined e-commerce server Maintaining a database that stores the rating of the content being traded, if the rating identification unit 360 requests a rating for the content, the e-commerce server may transmit information about the rating in response to the request.

The access restricting unit 370 restricts access to the packet related to the content of the user by referring to the content class identified by the class identification unit 360 and the user class of the user. The user class may be received from the user terminal 301 and recorded and used in a predetermined storage device, or may be stored in a portable storage medium readable by the media reader 350 and then read and used by the media reader 350. . In order to restrict access to the packet, the packet may be discarded without being delivered to the user terminal 301, and as in the relay unit 330, the user may add predetermined data representing an unauthorized packet to the packet. The packet may be ignored by the P2P e-commerce client program installed in the terminal 301.

The activation unit 380 receives an activation password from the user terminal 301 and activates the accountless billing processing device 302 according to the activation password. The activation unit 380 receives the activation password from the user terminal 301 in advance and stores the activation password in a predetermined storage device. When the user inputs the activation password through the user terminal 301 for activation, the activation password stored in advance and Compare the activation password entered by the user to activate the accountless billing processing unit 302 only if the same. Therefore, since the accountless processing unit 302 is activated only when there is an activation password input by the user, it is possible to prevent other users from using the P2P e-commerce system using the accountless processing unit 302 arbitrarily. It works.
