Embodiment Construction

[0193] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0194] like figure 1 Shown, embodiment of the present invention and concrete implementation process thereof are as follows:

[0195] A. Generate a key:

[0196] Each user of the buyer user and the seller user generates a user transaction key pair (pk C ,sk C ), where pk C Indicates the user transaction public key, sk C Indicates that the user trades the private key, and the user pk the public key in the key pair C Send to the data trading platform, and pk C =sk C P, P represents the generator of cyclically added groups; and for the user transaction key pair (pk C ,sk C ), the transaction key pair of the buyer user is expressed as The transaction key pair of the seller user is expressed as

[0197] During each transaction between any seller user and buyer user, the data transaction platform generates...

Abstract

The invention discloses a multi-signature transaction information processing method for a data transaction platform based on a block chain. Each of a buyer and a seller generates a transaction key pair at self client, and the data transaction platform generates and distributes a single transaction key pair for each transaction process; the seller releases data to be transacted on the block chain via the data transaction platform; after the buyer submits a transaction application, an intermediate address is generated according to a three-party public key, money is transferred to the intermediate address after payment, and the seller receives the money, writes the money into the block chain, then encrypts data and sends the encrypted data to the buyer; after the buyer receives the data, if transaction is acknowledged, the double parties sign, and the money is transferred to the address of the seller; and if objection exists, the data transaction platform makes a judgment, and determines to transfer the money to the buyer or the seller according to the judgment result. Data and transaction information during transaction of the double parties are processed in a special regional chain manner, and meanwhile, the data transaction platform cannot embezzle the transaction money, so that the security of digital assets during transaction is further guaranteed.

Description

technical field [0001] The invention relates to a multi-signature method, in particular to a method for processing multi-signature transaction information in a blockchain-based data transaction platform in the technical field of blockchain. Background technique [0002] With the rapid development of cloud computing and the Internet of Things, more and more data has been recorded and saved, and it has now entered the era of big data. Data trading is an inevitable demand of the market and reality. In order to maximize the value of data, data trading centers have been established in various places. However, due to the particularity of data, such as easy copying and no clear ownership constraints, it is difficult to guarantee data security and rights, so companies and individuals do not want to Take the data out and share the transaction. [0003] In order to better ensure data security and the rights and interests of enterprises and individuals, existing people have proposed ...
