Abstract
The present invention relates to a technology for building a data marketplace centered on P2P (Peer-to-Peer) based file data transfer function without a central server and a block chain-based password money payment function, Therefore, there is a characteristic that content price and transmission participant are determined. It is advantageous that a plurality of participants can deal with a file or contents without paying attention to each other by paying a password using a block chain and distributing profit.
Description
The present invention relates to a technique for constructing a data marketplace centered on peer-to-peer (P2P) file data transmission and block-chain-based password settlement.
More particularly, the present invention relates to a method and system for performing a payment through a block-chain-based cryptography in the case of a user purchasing a specific file in a data marketplace, a P2P-based (S11), the distribution participant list is provided so that the user can receive the file, and the distribution fee is distributed to the transmission participant and the fee proprietors thereof.
Conventional traditional peer-to-peer (P2P) data transmission environments do not provide payment and profit sharing functions for content.
For this reason, after receiving all of the files, there is no gain in the P2P file transmission behavior, so the file is not shared. As time passes, the share is gradually reduced and the peer (C2) The user who wants to download the file last will not be able to receive the file.
In addition, free content may be maliciously distributed to normal content, including computer viruses, Trojan horses, and Ransomware.
The underlying data marketplace has been implemented in such a way that it is downloaded directly from a central server that does not transmit data on a P2P basis.
For this reason, it has been cost prohibitive to keep the central server online, and therefore, non-mainstream data or contents that are not sought by many people have not been sold.
In addition, existing data marketplaces can only settle in general legal currencies. In this case, participating transit participants in other countries have difficulties in allocating profits to small amounts due to the burden of exchange fees and exchange fees for international remittances.
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to solve the above-mentioned problems by adding a password settlement function and a settlement step which were not present in the existing P2P file transfer environment and file marketplace configuration.
Users tend to justify paying for valuable materials, so they can choose to pay for data that is more reliable than free, thereby providing benefit to the transmission participants, thus ensuring that the transmission participants remain on the sender role And provides a way to build a data marketplace that allows participants from different nationalities to participate.
In order to achieve the above object, the present invention provides a P2P transmission-based data marketplace comprising a block-chain-based cryptographic billing function and a method thereof, which comprises the steps of: A transmission participant grouping unit 320 for grouping the transmission participants; A transmission participant assignment unit 330 for determining in the transmission participant group whether to be included in the priority or list of assignments by an algorithm; A participating contribution settlement unit 340 for distributing the encrypted password to the peers (C2) participating in the file transfer and those having the right of commission; And a block chain transaction transmitting unit (370) for performing a transfer function of the encrypted money. The network system according to claim 1, further comprising: a tracker (B2) (230); And a block-chain transaction transfer unit 270 for transferring the encrypted password to the P2P client B4.
Preferably, the file encryption unit 240 encrypts the file. And a file decryption unit (250) for recovering the file to an original file using the encryption key, and a cryptographic key generation unit (250) for generating a cryptographic key used for encrypting and decrypting the file And a tracking unit (B2) configured to further include a generating unit (350).
In determining the priority or inclusion of the assignment in the algorithm operating in the transmission participant assignment unit 330, the deciding factor is the
Requesting a transmission participant list (S06) for the P2P client (B4) to perform P2P data communication from the tracker (B2); A sender list providing step (S08) in which the tracker (B2) provides the sender list to the P2P client (B4); A coin settlement step (S09) in which the user (C1) transfers a block-chain-based encrypted currency to a tracked account address of the tracker; A file transmission step (S10) of receiving a file by dividing a file into a fragment unit from a plurality of transmission participants based on P2P; And a contribution fee payment step (S11) for distributing the cryptographic proceeds to the peer (C2) contributing to each transmission and those having the fee right.
The present invention has an advantage in that people in the world can participate in settlement and profit distribution by allowing contents to be purchased through a password money settlement in a P2P data transmission environment.
In addition, since the settlement of accounts is made with a password, there is an advantage that there is no burden of a fee for transfer and loss of a small amount of cutting.
In addition, it is expected that the distribution of high-quality paid content can be expected compared with the existing P2P file sharing environment in which most of the free content files are.
Also, based on P2P transmission, it is not necessary to directly construct a file transfer server in a group that intends to build a data marketplace, and there is no need to bear the traffic cost, which is advantageous in that the operation cost is greatly reduced.
