Abstract

The invention discloses a data security transmission method. The method includes: when a task creation instruction is received, creating a shared task corresponding to the task creation instruction, and uploading the shared task to a preset main chain; When downloading the instruction, download the shared task from the preset main chain, and obtain external source data from outside the sharing system by running the source data acquisition contract in the shared task; encrypt the external source data to obtain encrypted source data, and encrypt the encrypted source data. The source data is uploaded to the preset main chain; when the download instruction issued by the target node is detected, the shared task and encrypted source data are downloaded from the preset main chain, and the contract is obtained by running the target data in the shared task, and the encrypted shared data is processed. Decrypted so that the target node obtains the external source data. The invention also discloses a data security transmission device, equipment and readable storage medium. The present invention realizes the safe transmission of data under the condition of reducing the use of the block chain.

Description

technical field [0001] The present invention relates to the field of data security, and in particular, to a data security transmission method, apparatus, device and readable storage medium. Background technique [0002] In a blockchain-based data sharing and exchange system, it is usually through the use of blockchain smart contracts to interact with external data. For example, real-time price data of stocks, weather forecasts, market forecasts and other data, but the blockchain is a closed environment, and the chain cannot actively obtain real-world data outside the chain. [0003] The mechanism for writing information outside the blockchain into the blockchain is generally called an oracle. The function of the oracle is to write external information into the blockchain to complete the data exchange between the blockchain and the real world. However, after the information is written into the blockchain, the direct data sharing and exchange through the blockchain has proble...
