Abstract

A method comprises the steps: receiving to-be-stored data uploaded by a user, collecting storage key information of the to-be-stored data, and uploading the to-be-stored data to an interstellar file system; verifying the to-be-stored data by utilizing the interstellar file system, after the verification is passed, fragmenting the to-be-stored data by the interstellar file system, storing the fragmented to-be-stored data to different nodes, and generating a hash value for each fragment of the to-be-stored data in the interstellar file system; and storing the hash value and the evidence storagekey information in transaction record detail information in the form of a blockchain transaction record based on an intelligent contract, establishing a corresponding mapping relationship between theuser and related data, and respectively storing the transaction record detail information in a blockchain and a database. Through the decentration characteristic of the blockchain, and in combinationwith the distributed storage characteristic and encryption strength of the interstellar file system, higher tamper-proof capability is effectively realized.

Description

technical field [0001] The invention relates to the technical field of computing data security, in particular to a method and system for storing data certificates based on a blockchain and an interplanetary file system. Background technique [0002] In the traditional electronic depository platform, data is generally stored in a centralized manner, and the operator of the platform endorses it through its own credit, or cooperates with a notary public to increase its authority. Nevertheless, the problem of tamper resistance has not been effectively solved in the technical nature. With the in-depth exploration of the application of blockchain technology, its decentralization, tamper-proof and traceability effectively solve the pain points of traditional depository platforms. An electronic depository platform using blockchain can provide multi-party depository services in conjunction with authoritative institutions such as judicial authentication, auditing, notarization, and a...
