Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0055] Based on the relatively low security of the data recorded in the current blockchain, this application provides a data processing method based on the blockchain, which can prevent the data in the blockchain from being illegally Read, improve the security of data in the blockchain. First introduce the data processing system applied by the blockchain-based data processing method, such as figure 1 As shown, the data processing system may include a blockchain network, a first terminal an...

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain and a terminal, and the method comprises the steps: receiving an obtaining request, sent by a second terminal, for target data, obtaining a secret key pair corresponding to a first terminal, and enabling the secret key pair corresponding to the first terminal to comprise a second private key and asecond public key; encrypting the target data by adopting the second public key to obtain a ciphertext of the target data; encrypting the second private key by adopting the first public key to obtaina ciphertext of the second private key; and storing the ciphertext of the second private key and the ciphertext of the target data in a blockchain network, so that the second terminal reads the ciphertext of the second private key and the ciphertext of the target data from the blockchain network, and decrypts the ciphertext of the target data according to the ciphertext of the second private key to obtain the target data. Through the embodiment of the invention, the security of the 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 ...
