Embodiment Construction

[0041] As mentioned in the background art, the existing data transaction methods usually use a centralized service platform for data transactions, which has some shortcomings. For example, once the centralized service platform is attacked, the security of transaction data and transaction funds are threatened; and usually after the transaction is completed, the centralized service platform transfers the money, which is inefficient. It can be seen from the above that the current data transaction method needs to be optimized.

[0042] In the embodiment of the present invention, through the smart contract running on the block chain and the authentication of the transaction data before the transaction, it is possible to avoid breach of contract or use of unsafe transaction data for transactions during the transaction process, thereby ensuring data The security of transactions improves the efficiency of data transactions.

[0043] In order to make the above objects, features and be...

Abstract

The invention discloses a data transaction method and system, a platform and a storage medium. The data transaction method comprises the steps of authenticating transaction data of a data supplier; when the authentication is passed, receiving ciphertext data obtained by encrypting the transaction data by the data supplier, and confirming a data demander; Creating an intelligent contract accordingto the transaction demand of the data demander and issuing the intelligent contract to a block chain; when it is monitored that the smart contract locks the transaction money of the data demander, a transaction request is sent to the data supplier; when it is confirmed that the data supplier agrees with the transaction request and receives a re-encryption key, re-encrypting the ciphertext data toobtain re-encrypted data; And triggering the smart contract to send the transaction money of the data demander to the data supplier, and notifying the data demander to extract the re-encrypted data and decrypt the re-encrypted data to obtain the transaction data. By adopting the data transaction method, the data transaction efficiency and safety can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data transaction method, system, platform, and storage medium. Background technique [0002] With the development of the Internet and the prevalence of online transactions, Internet transactions have become the preferred method for more and more people. Internet transactions provide great convenience to people's lives, especially data transactions. [0003] At present, during the entire transaction process, since the parties to the transaction cannot establish a trust relationship, the transaction data is transferred by the centralized transaction platform, and usually after the transaction is completed, the transaction is transferred by the centralized service platform. [0004] However, using a centralized service platform for data transactions is difficult to guarantee the security of transactions, and the transaction efficiency is low. Contents of the invention...
