System and method for providing P2P contents / services {P and P2P service}

The present invention relates to a system and method for providing P2P content / service, and more particularly, to provide digital content sharing and various services in a P2P manner by using a terminal device of a user in a ubiquitous wired / wireless Internet environment. The present invention relates to a P2P content / service providing system and method for providing a service for a fee and separating the authentication and payment to use the content or the service in a secure state regardless of the P2P membership.

In general, P2P (peer-to-peer) technology is an individual device that has various wired / wireless communication methods such as the Internet, mobile communication, and ad-hoc network using personal terminals including computers in ubiquitous environment. It means a tool that allows to share various information and contents.

In addition, P2P service is a service that can receive information directly from all personal terminals connected to wired / wireless communication network, search as well as download information, unlike the existing method that the server must find information on the Internet through a search engine. Information extraction paths can be extended to databases operated by individuals or companies.

Currently, P2P service has the advantage of sharing the desired file by searching the computer of individual users connected to the Internet, but there is a problem that the authentication system and the billing system are not properly equipped.

Most commercially available P2P services operate on a membership system with an intermediary web server, so that P2P transactions can be made after real name verification and membership authentication.

However, in the conventional method, the purchaser has to register as a P2P member in order to purchase a service provided by the P2P seller, and the purchaser needs a membership certification to receive the P2P service certification.

Accordingly, in the conventional P2P service provision, a commercial P2P service could not be provided to a P2P service purchaser or user who has not subscribed as a P2P member.

In addition, a communication environment for providing or using a P2P service is not only a wired / wireless Internet environment but also a wireless broadband, Wi-Fi (Code Division Multiple Access), a wideband CDMA (WCDMA), and a high-speed downlink packet access (HSDPA). It is not directly connected to mobile and mobile internet environment, terminal inside firewall, and wired / wireless internet, but various serial / parallel such as short range wireless interface such as Bluetooth or IR (Infra Red) Port, RFID (Radio Frequency Identification), USB, IEEE 1394, etc. Ad-hoc network environments, such as a terminal environment connected to a computer in a wired or wireless Internet environment through a wired interface such as a cable, should be considered.

In the past, a service that separates member authentication and purchase service authentication is used by a software vendor to open a web shopping mall and provide a secret URL so that only the purchaser can download the software to the e-mail address registered when the user pays by credit card. In some cases, this is a method of simultaneously operating a shopping mall server and a content server on an intranet on a wired Internet, which is far from a P2P environment with a flexible IP or service location, and purchases digital content or commercialized services in a P2P manner.

Instead, authentication may be performed by directly accessing the P2P providing terminal 20.

In addition, since the P2P service user once authenticated via the intermediary server 110 can directly access the same P2P access URL again, in this case, the authentication processing unit 146 is configured in the P2P agent to perform authentication. have.

Now, in the embodiment of the above-described P2P content / service providing system, a method for providing P2P content / service will be described in detail.

6 is a flowchart illustrating an embodiment of a method for providing P2P content / service according to the present invention.

Referring to Figure 6, the P2P content / service providing method according to the present invention goes through the following process.

First, a P2P providing terminal 20 to provide content / service stored in the terminal as a P2P service registers a P2P service member to the P2P service providing system 100 through the Internet network and then provides a P2P service from the P2P service providing system 100. An agent is downloaded to the P2P providing terminal (S61).

Second, after the P2P service agent is started, the P2P providing terminal 20 is registered in the P2P service providing system 100 and the P2P service agent provides a path to the P2P authentication server 130 by the P2P service agent. The virtual P2P connection URL of the providing terminal 20 is set (S62).

Here, the P2P access URL is described, the P2P access URL is to recognize the registered specific P2P providing terminal 20, when the P2P providing terminal 20 is registered in the P2P authentication server 130. A virtual P2P connection URL is set by the service agent and uniquely recognized by the gateway server 120.

The P2P access URL is a P2P URL mapping unit 124 of the gateway server 120 when the P2P providing terminal 20 uses an unauthorized IP in a firewall or under an ad-hoc network environment. It is used to provide a unique P2P URL by making a direct connection with the providing terminal 20. That is, the P2P access URL acts as a P2P access path and also serves as a P2P URL including substantial content or commercial service.

On the other hand, in the case of a public IP environment in which the P2P providing terminal 20 does not have a firewall installed, the virtual P2P access URL becomes a temporary P2P URL providing a path of the gateway server 120, and the P2P URL mapping unit 124. By providing the actual P2P URL provided by the P2P providing terminal 20, when the P2P using terminal 30 is authenticated, the actual location containing the content or commercial service is a P2P URL.

Third, the P2P sharing target content / service is selected by selecting among the contents / services stored in the P2P providing terminal 20 registered in the P2P service providing system 100, and the set contents / service list is set as a P2P mediation server ( In step 110, the web is posted through a web browser (S63).

Fourth, the P2P user terminal accesses the P2P service providing system to search for a web / published content / service list, and purchases and pays for the content / service (S64).

Fifth, the access authentication key for the content / service set as the P2P sharing target is issued and transmitted to the P2P providing terminal 20 (S65).

Sixth, the P2P access terminal 30 transmits the P2P access URL and the authentication key to the P2P use terminal 30 to which the P2P user terminal 30 authenticates access (S66).

Here, the P2P user terminal 30 may be a terminal of a user who has not subscribed to a P2P service as well as a member who has subscribed to a P2P service, and a third party different from a user who directly purchases and pays the P2P content / service. Now you can.

Seventh, the P2P user terminal 30 accesses the transmitted P2P access URL, inputs the authentication key, performs an authentication procedure, and then accesses the content / service purchased through a P2P connection to the P2P URL where the content / service is stored. It is a step of accessing (S67).

Here, when the P2P using terminal 30 accesses the transmitted P2P access URL and inputs the authentication key, the authentication server 130 matches the authentication key transmitted to the P2P using terminal 30. The P2P user terminal 30 is authenticated and the providing system 100 permits P2P access of the P2P user terminal 30 to the P2P URL where the content or commercial service is stored to access the content or commercial service.

However, if the authentication key does not match, the authentication fails and the P2P URL is not provided to the user, so that the service using terminal 30 cannot access content or commercial services.

Next, the P2P service agent 140 provides the P2P content / service, and transmits a usage log to the P2P service providing system 100 (S68).

The content provided by the service agent 140 allows to show or download various multimedia contents such as music, video, photo / image, ebook, document / folder.

In addition, the service agent 140 is a commercial service, and even if the execution software or application is not installed in the P2P user terminal 30, music service, video viewing, photo / picture viewing, e-book viewing, or real-time multimedia streaming can be performed. Or provide services such as remote digital device control.

Finally, the P2P service providing system 100 transmits P2P content / service usage and billing history statistics to the P2P providing terminal 20 and the P2P using terminal 30 (S69).

Here, the authentication process is processed by the authentication processing unit 146 of the service agent 140 in the P2P providing terminal 20.

On the other hand, in the step of setting the P2P sharing target content, commercial service by selecting from the content stored in the P2P providing terminal 20 registered in the P2P providing system 100, commercial service (S30), the P2P sharing A password can be set for content or commercial services set as targets.

In this way, the owner or user of the terminal 20 can control the access level for each P2P sharing target content or type of commercial service to the service user accessing the P2P through the P2P URL, so that the P2P service user authenticates. After authentication by inputting a key, access may be granted only when the additional password is set, and access rights may be variously granted by setting the password or by another method.

Meanwhile, in addition to setting a password, the method may include inputting a mobile phone number of the user when the terminal of the P2P service user is a mobile phone in the user authentication step.

This may be useful for billing purposes or as an aid to real name verification.

7 is a flowchart illustrating yet another embodiment of a method for providing P2P content / service according to the present invention.

First, a P2P providing terminal 20 to provide content / service stored in the terminal as a P2P service registers a P2P service member to the P2P service providing system 100 through the Internet network and then provides a P2P service from the P2P service providing system 100. An agent is downloaded to the P2P providing terminal (S71).

Second, after the P2P service agent is started, the P2P providing terminal 20 is registered in the P2P service providing system 100 and the P2P service agent provides a path to the P2P authentication server 130 by the P2P service agent. A virtual P2P connection URL of the providing terminal 20 is set (S72).

Third, the P2P sharing target content / service is selected by selecting among the contents / services stored in the P2P providing terminal 20 registered in the P2P service providing system 100, and the set contents / service list is set as a P2P mediation server ( In step 110, the web is posted through a web browser (S73).

Fourth, the P2P user terminal accesses the P2P service providing system, searches for a web-published content / service list, and purchases and pays for the content / service (S74).

Fifth, the access authentication key for the content / service set as the P2P sharing target is issued and transmitted to the P2P providing terminal 20 (S75).

 Sixth, the P2P service providing system 100 transmits the mediation URL and the authentication key to the P2P using terminal 30 as a connection window for performing the authentication procedure (S76).

Next, when the P2P user terminal 30 accesses the transmitted intermediary URL, inputs the authentication key and performs an authentication procedure, the P2P service providing system guides to the P2P access URL, and the P2P access URL is Permit P2P access of the P2P user terminal to the P2P URL where the content / service is stored (S77).

Here, the mediation URL guides for the authentication connection provided by the P2P mediation server 110, and the initial authentication procedure for the authentication key is performed in the providing system 100, but then the P2P connection is again performed. Since the P2P URL may be provided to the P2P providing terminal 30, the authentication processing unit 146 of the service agent 140 of the P2P providing terminal 20 may be processed as the authentication key delivered in step S75.

Next, the P2P service agent 140 provides the P2P content / service and transmits the usage history log to the P2P service providing system (S78).

Finally, the P2P service providing system 100 transmits P2P content / service usage and billing history statistics to the P2P providing terminal 20 and the P2P using terminal 30 (S79).

8 is a flowchart illustrating P2P content / service providing when the P2P content / service providing terminal is not online.

The virtual server 117 of the P2P service intermediation server 110 checks the state of the P2P providing terminal corresponding to the P2P URL where the content / service is stored, and when not in the online state, the P2P connection of the P2P service terminal of the P2P service providing system. The method may further include guiding the virtual server to provide P2P content / service.

6 and 8, the P2P service providing system 100 first accesses a P2P access URL and checks the P2P access URL in order to access the content / service purchased by the P2P user terminal 30. As to whether the P2P providing terminal 20 is in a state capable of P2P service, the online state checking unit 126 of the gateway server 120 checks whether the P2P connection is available in the online state through which the P2P connection is possible. (S90).

In this case, when the P2P providing terminal 20 is online and accessible using the P2P URL, steps S67 and S68 are typically performed in FIG. 6.

However, when the P2P providing terminal 20 is not online and the connection is not possible through the P2P URL, the P2P providing terminal 20 guides the access back to the virtual server 117 which has synchronized and stored the content / service set as the sharing target. After the authentication process, the content / service can be accessed (S91).

Thereafter, when the virtual server of the P2P service providing system 100 provides the content or commercial service purchased from the P2P using terminal 30 and transmits the usage history log to the intermediary server 110 in the virtual server 120, The P2P service providing system 100 transmits the P2P content / service usage and billing history statistics to the P2P providing terminal 20 and the P2P using terminal 30 (S69).

Here, also in FIG. 7, when the P2P providing terminal 20 is online and can be accessed using the P2P URL, steps S77 and S78 are normally performed, and if connection is not possible, S90 after step S76. Steps S91 and S92 are performed.

9 is an embodiment of authentication and payment for use of P2P content / service according to the present invention.

9a is an authentication screen for using a P2P service, and 9b is a purchase screen for P2P content / service.

On the P2P service authentication screen of 9a, a P2P access URL and an authentication key necessary for performing the authentication procedure are transmitted to an e-mail or a mobile phone.

In addition, in the payment of 9b, purchase payment can be made using a credit card, bank transfer, mobile phone payment, and telephone payment, and an example of mobile phone payment is shown.

9, in the P2P service providing method according to the present invention, service authentication and payment authentication are separated.

In other words, when performing the authentication procedure on the P2P service authentication screen, the P2P user terminal to be transmitted is assigned an authentication path to the P2P terminal of the purchaser and other users, and transmits the necessary P2P access URL and authentication key to the e-mail or mobile phone. You can have third parties other than the purchaser use the P2P service.
