The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. The technical solution of the present disclosure is described in various aspects below with reference to various figures and embodiments.
Hereinafter, "first", "second", etc. are only descriptive differences and have no other special meanings.
Fig. 1 is a schematic flow chart diagram of an embodiment of a data storage method according to the present disclosure, as shown in fig. 1:
There are many ways to store files. For example, a file chunk is generated from a file, the file chunk is distributed in a chunk chain, or the file is stored in an object storage cluster (the file is stored as an object).
And 105, obtaining a first operation authority from the first operation contract, and correspondingly operating the file based on the first operation authority and the operation request.
The block chain technology is a common account book technology based on consensus, and has the characteristics of no center, no tamper property, openness and transparency and the like. The blockchain technology utilizes a blockchain data structure to verify and store data, utilizes a distributed node consensus algorithm to generate and update data, utilizes a cryptographic approach to secure data transmission and access, and utilizes an intelligent contract composed of automated script code to program and manipulate data, which is a completely new distributed infrastructure and computing approach.
In the data storage method in the above embodiment, a high-reliability storage service may be implemented based on a blockchain technique, and when a file storage request sent by an object storage client is received, a first operation restriction block corresponding to a file object is recorded by using the blockchain technique, where the first operation restriction block includes a first operation contract, and the first operation contract includes a first operation permission, that is, an executable operation on the file. When a user needs to execute a certain operation, the operation is verified based on the first operation limiting block, so that the control over the operation of all data is achieved, and data tampering and data embezzlement are avoided.
In one embodiment, it is determined whether the operation request sent by the user matches the first operation right. For example, if the operation request is to perform query operation on a file, and the first operation permission is that a user can only perform query operation on the file, the operation request is matched with the first operation permission; and if the operation request is to delete the file, the operation request is not matched with the first operation authority.
And if the operation request is matched with the first operation authority, acquiring a file block corresponding to the file from the block chain, acquiring the file from the file block, and performing corresponding operation according to the operation request, such as query operation and the like.
The general mechanism of the block chain, such as a public key/private key mechanism, a data signature and the like, can ensure the credibility of both information interaction parties and the credibility of transactions, and the adoption of a consensus mechanism of the block chain ensures the consistency and the non-tamper-ability of data.
And if the operation request does not match the first operation authority, starting a consensus mechanism and sending a modification request to each node in the block chain. The modification request includes: a second operation authority corresponding to the operation request, and the like, wherein the second operation authority may be an authority for deleting a file and the like. Each node of the block chain negotiates the modification request based on the intelligent contract, and correspondingly processes the file based on the negotiation result and according to the second operation authority.
An intelligent contract is a piece of code stored on a blockchain that can be triggered by an operation on the blockchain, and after triggering, the piece of code can read data from the blockchain or write data to the blockchain. An intelligent contract is a collection of code and data, and intelligent contracts can be of various kinds.
If the negotiation result of each node of the block chain for the second operation authority is to agree to modify the first operation authority, generating a second operation contract, wherein the second operation contract comprises: and a second operation right. And generating a second operation limiting block according to a second operation contract, issuing the second operation limiting block in the block chain, so that each node in the block chain replaces the first operation limiting block with the second operation limiting block according to the intelligent contract, and storing the operation limiting information of the file through the second operation limiting block. And acquiring the file blocks from the block chain, acquiring the files from the file blocks and operating according to the operation request.
And if the negotiation result of each node of the block chain on the second operation authority is that the first operation authority is not approved to be modified, the operation cannot be carried out according to the operation request. And when the operation is forbidden, the second operation restriction block cannot be linked up and is forbidden, so that the data access is effectively restricted.
The data storage method in the above embodiment can be implemented by modifying the source code of the object storage server, and the operation of the block chain is completely transparent to the user, so that the user does not need to perform additional research and development work due to the requirement on data security.
Fig. 2 is a schematic flowchart of an operation performed on a stored file according to an embodiment of the data storage method of the present disclosure, as shown in fig. 2:
In step 206, each node of the blockchain negotiates a modification request based on an intelligent contract.
And step 207, if the negotiation result is that the modification is approved, generating a second operation contract, wherein the second operation contract comprises: and a second operation right.
And step 208, generating a second operation limiting block according to the second operation contract, and issuing the second operation limiting block in the block chain.

The second operating contract comprises: file ID and storage node ID, etc.
When the file is uploaded, the object storage server uploads the object ID, the first operation authority, the storage cluster ID and the like which are obtained after the file is split into the objects as a first operation contract to the block chain cluster according to the operation limit of the configuration file on the file. When the uploaded file is operated, if the operation is not limited, the operation is normally carried out; if the operation is restricted, the object ID, the second operation right, and the storage cluster ID need to be uplink-operated, so that most nodes in the blockchain cluster can recognize the operation and the operation can be continued, i.e. the operation is normally prohibited.
When generating a file block according to a file, the file is encrypted based on an encryption key, the encryption key is added into a first operation contract, and the file block is generated according to the encrypted file. An encryption key is obtained from a first operation contract. And obtaining the encrypted file from the file block and decrypting the encrypted file according to the encryption key.
