A blockchain data processing method and device

Abstract

The embodiment of the present application discloses a block chain data processing method and equipment, wherein the method includes the following steps: acquiring the target user's sign material, and acquiring the target user's DNA (deoxyribonucleic acid) information according to the sign material; according to the DNA The information generates the DNA characteristic data of the target user; adopts a hash algorithm to convert the DNA characteristic data into a hash value, and uses the hash value as the private key of the target user; adopts the private key pair of the target user The DNA information and the target user are encrypted to obtain ciphertext, and the ciphertext is sent to the block chain node, so that the block chain node generates the block corresponding to the ciphertext, and the block is added into the blockchain. By adopting the application, the risk of information leakage can be reduced, and the security of data can be improved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a blockchain data processing method and equipment. Background technique [0002] With the rapid development of the Internet, while people are enjoying the convenience of the Internet, more and more attention has been paid to its security issues. In particular, hackers on the network pretend to be legitimate users to receive or send data, and information receivers forge and tamper with data, etc., occur from time to time, which bring huge hidden dangers to people's lives. Through blockchain technology, the security of data received or sent between users can be guaranteed, and data forgery and tampering can be prevented. However, at present, the private keys of users in the blockchain system are randomly generated strings, and private keys need However, there is still a risk of information leakage if mnemonic words and other means are used to save the data, and it ca...

Problems solved by technology

In particular, hackers on the network pretend to be legitimate users to receive or send data, and information receivers forge and tamper with data, etc., occur from time to time, bringing huge hidden dangers to people's lives

Through blockchain technology, the security of data received or sent between users can be guaranteed, and data forgery and tampering can be prevented. However, at present, the private keys of users in the blockchain system are randomly generated strings, and private keys need There is still a risk of information leakage, and there is no guarantee that the security and privacy of user data will not be threatened
