Information processing method and device based on block chain and computer readable storage medium

Abstract

The embodiment of the invention discloses an information processing method based on a block chain, and the method comprises the steps: obtaining an original index information set which comprises at least one piece of original index information, wherein each piece of original index information comprises sensitive content in a plaintext form; obtaining information in the to-be-matched block, the information comprising information content and an information index, and the information content and the information index having a corresponding relationship; matching information contents in the information through the original index information set to obtain a matching result; and when the matching result indicates that the matching is successful, generating variant index information set variant index information according to the matching result, wherein the variant index information set variant index information comprises an information index in information in the to-be-matched block. The invention further discloses an information processing device. The specific content of the index information is not directly displayed, and maintenance is carried out in an information index mode, so thatpotential safety hazards are not prone to occurring, and the safety of information maintenance is improved.

Description

Technical field [0001] This application relates to the field of computer technology, and in particular to a blockchain-based information processing method, device and computer-readable storage medium. Background technique [0002] With the development of computer technology, blockchain data processing technology continues to develop. Blockchain technology (BT), also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization and openness and transparency, allowing everyone to participate in database records. Block chains currently mainly include public chains, private chains, alliance chains, permission chains, and hybrid chains. [0003] Transactions based on blockchain technology need to consider the security of transaction information. The current solution is based on a plaintext sensitive vocabulary. Specifically, the service provider maintains a plaintext sensitive vocabulary. When the user needs content detection and ...

[0004] However, the currently used sensitive thesaurus is maintained in a centralized organization in the form of clear text. When it is necessary to update the sensitive thesaurus, a clear text sensitive thesaurus file is usually used to synchronize the latest sensitive words. Therefore, If the carrier file of the sensitive lexicon is leaked during the synchronization process, it will lead to security risks in transaction information and cause a series of social hazards
