METHOD AND SYSTEM FOR MIMICRY STORAGE TAMPER-PROOF LOG FUSED WITH BLOCKCHAIN TECHNOLOGY

摘要

A method for a mimicry storage tamper-proof log fused with blockchain technology, comprising: S1. collecting logs of each heterogeneous body in a mimicry storage system and converting same into logs with a standard format; S2. sending the converted standard logs to a blockchain network node, and the blockchain network node packaging the logs into a transaction; S3. the blockchain node sending the transaction to a manager node, and the manager node storing the logs in a preblock; S4. the manager node sending the preblock to a committee member node, and the committee member node verifying the preblock and sending a signature to the manager node; S5. the manager node determining whether more than half of the signatures of the committee members are collected; and S6. each node synchronizing the received new blocks into a blockchain. Using a block chain as a mimicry storage system log storage module can protect the mimicry storage logs from being tampered with. The process of generating a block by using a PoV algorithm is relatively low in communication complexity, is relatively good in performance, and is strong in expandability, and facilitates an increase or decrease in the number of cluster nodes.
