Blockchain-based data processing method, device and terminal

Abstract

The embodiment of the present application discloses a blockchain-based data processing method, device, and terminal, wherein the method includes: receiving an acquisition request for target data sent by a second terminal, acquiring a key pair corresponding to the first terminal, The key pair corresponding to the first terminal includes a second private key and a second public key; use the second public key to encrypt the target data to obtain the ciphertext of the target data; and use the first public key to encrypt the target data The second private key is encrypted to obtain the ciphertext of the second private key; the ciphertext of the second private key and the ciphertext of the target data are stored in the block chain network, so that the second terminal can obtain the ciphertext from the area The ciphertext of the second private key and the ciphertext of the target data are read in the block chain network, and the ciphertext of the target data is decrypted according to the ciphertext of the second private key to obtain the target data. Through the embodiments of the present application, the security of data in the blockchain can be improved.

Description

technical field [0001] The present application relates to the field of block chain technology, and in particular to a block chain-based data processing method, a block chain-based data processing device, and a terminal. Background technique [0002] Blockchain is a new application mode of distributed data storage, point-to-point transmission (P2P transmission), consensus mechanism, encryption algorithm and other computer technologies. Allow multiple parties to effectively record data, and the recorded data can be read and verified (that is, anti-counterfeiting). In practice, it has been found that due to the existence of illegal personnel who read data from the blockchain and use the read data for profit, it brings great mental and economic losses to the data owner. Based on this, how to improve the security of data in the blockchain is an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present ...
