Abstract

The invention discloses a data processing method based on a block chain. The method comprises the following steps: encrypting private data according to a data key of a signer and a preset encryption algorithm to obtain a data ciphertext; recording a timestamp generated by carrying out block generation on the privacy data at this time; obtaining a new data block according to the data ciphertext, the timestamp and the hash value of the previous data block of the privacy data; sending the signature message of the new data block to a verification node for verification; when the verification node passes the verification, adding the new data block into a pass issued by the signer in a block chain system; wherein the pass comprises an excrement field, and basic information of private data bound with the pass is recorded in the excrement field. The invention further provides a data processing device based on the block chain and a computer readable storage medium. The privacy data of the user can be stored through the block chain, and the privacy data can be safely stored.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a data processing device, method and computer-readable storage medium based on block chains. Background technique [0002] Blockchain is a new type of decentralized protocol, which can safely store digital currency transactions or other data. The information cannot be forged and tampered with. The transaction confirmation on the blockchain is completed by all nodes on the blockchain. The consensus algorithm To ensure its consistency, a public ledger is maintained on the blockchain, and the public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. In cryptocurrency applications such as Bitcoin, the blockchain saves the user's transaction information, and in smart contract applications such as Ethereum, the blockchain saves the user's smart contracts. If the user has private data that he does not want to discl...
