Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] The purpose of the present invention is to provide a block chain-based P2P network cloud storage method in a big data environment, that is, by using the block chain as a transaction mechanism, the data is encrypted in blocks and randomly stored in the entire P2P network to provide a fixed size At the same time, the Merkle hash tree is used to verify the integrity of all transaction information in the network, which greatly guarantees the security of data in cloud storage.

[0025] Blockchain: Blockchain (Blockchain) is an additive-only distributed database that stores all transactions sorted by time and widely accepted by all users. Blockchain is an underlying technology behind Bitcoin. It has come into people's sight after the success of Bitcoin. Its characterist...

Abstract

The invention relates to a block-chain based P2P network cloud storage method in a big data environment. The block-chain based P2P network cloud storage method in the big data environment comprises the steps of dividing data into blocks, encrypting the data and numbering the data according to a sequence; uploading the processed data into a computer with idle storage space in the whole P2P network; storing an encrypted file in a computer around a user who needs the storage space randomly by regarding the block-chain as a transaction mechanism; and finally carrying out completeness verification for all the transaction information by using a Meckel Hash Tree in the network and detecting whether the transaction information is tampered. The block-chain based P2P network cloud storage method in the big data environment is characterized in that the related information of the stored file block rather than the file block per se is stored in the block-chain while encrypted file blocks are randomly stored in the computer around the user who needs the storage space.

Description

technical field [0001] The invention relates to the technical field of secure cloud storage, in particular to a blockchain-based P2P network cloud storage method in a big data environment. Background technique [0002] The concept of big data: big data (big data) refers to the collection of data that cannot be captured, managed and processed by conventional software tools within a certain period of time. Massive, high growth rate and diverse information assets of process optimization capabilities. Big data has 5V characteristics (proposed by IBM), which are Volume (mass), Velocity (high speed), Variety (variety), Value (low value density), and Veracity (authenticity). [0003] cloud storage: figure 1 It is a traditional cloud storage architecture diagram. Cloud storage is a network storage technology, which refers to the cloud storage service provider providing software and hardware infrastructure through functions such as cluster applications, network technology, or distr...
