Drawings
The accompanying drawings, which are included to provide a further understanding of the application and are incorporated in and constitute a part of this specification, illustrate embodiments of the application and together with the description serve to explain the application. In the drawings:
FIG. 1 is a schematic diagram of a file security management system based on a blockchain technique according to an embodiment of the present invention.
Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
Example 1
As shown in fig. 1, in this embodiment, a file security management system based on a blockchain technology is provided, including:
1.A file storage module: for encrypting the user's files for storage in the blockchain network. Each file has a unique address through which the contents of the file can be accessed. Meanwhile, in order to ensure the security of the file, the file storage module performs multiple signature verification on the file, and only a user who obtains enough rights can access the file.
The encrypted storage of the file is to encrypt the file by using a public-private key encryption algorithm, and only users with private keys can decrypt and access the file. Meanwhile, in order to prevent the file from being tampered with, a hash algorithm may be used to hash the file contents and store the hash value on the blockchain. Thus, even if someone tampers with the file content, the hash value can be detected as long as the hash value changes.
Multiple signature verification: to ensure the security of the file, a multiple signature verification mechanism may be employed. I.e. multiple users are required to sign together to access the file. For example, the access rights of a file may be assigned to multiple users, each of whom may need to provide their own private key for signature verification. The file can be accessed only after a sufficient number of user signatures pass. Thus, even if someone steals the private key, the file cannot be accessed.
2. And the permission management module is used for: for managing access rights of different users. The system can allocate different rights according to the identity and the roles of the users, for example, an administrator can manage and modify all files, and the ordinary users can only view and download own files. In addition, the authority management module can also realize the audit and tracking functions of the file access records so as to check the operation records of the user at any time. Therefore, the access authority of the file can be effectively controlled, and the safety of the file is ensured.
Backing up data: to prevent data loss or corruption, a data backup mechanism may be employed. Copies of the file are stored on multiple nodes to ensure reliability and integrity of the data. Meanwhile, version control technology can be used for carrying out version management on the file, so that a user can conveniently check a historical version and recover data.
3. And a distributed computing module: for handling a large number of data computing tasks. Because the blockchain network is a decentralised network consisting of a plurality of nodes, the computing tasks can be distributed to different nodes for processing through the distributed computing module, so that the parallelism and the efficiency of the system are improved. Meanwhile, in order to ensure the safety and reliability of data, the distributed computing module performs multiple signature verification on each computing result.
The distributed computing module is a computing model based on a distributed system architecture, which decomposes a large-scale data processing task into a plurality of subtasks, and executes the subtasks on a plurality of computers simultaneously, and finally merges the results. Such a computing mode can greatly increase the speed and efficiency of data processing, and particularly for complex computing tasks requiring processing of large amounts of data, distributed computing modules are of significant advantage.
In particular, a distributed computing module is typically composed of several parts:
(1) Task scheduler: and the task to be processed is distributed to different computing nodes for processing, and the running state and progress of each node are monitored.
(2) Computing node: is responsible for executing specific computing tasks, including data reading, data processing, result storage and the like.
(3) And a communication module: for data transmission and coordination between different nodes, messaging or RPC (remote procedure call) is typically used.
(4) And a data storage module: for storing intermediate and final results, it is usually implemented in a distributed file system or database, etc.
Through the cooperative work of the components, the distributed computing module can realize efficient data processing and analysis.
4. An intelligent contract module: business logic and rule control for automation. The system can automatically execute corresponding operations according to preset conditions and rules, for example, when the access times of a certain user exceed a certain threshold, the system can automatically limit the access authority of the user or send reminding information. In addition, the intelligent contract module can also realize the transaction and management functions of digital money, thereby facilitating the operations such as online payment, transfer and the like of users.
The intelligent contract module is a tool for automatically executing contracts based on the blockchain technology, and can realize automatic transaction and contract management without intervention of a third party organization. The smart contract module is typically composed of several parts:
(1) Programming components: the smart contract module typically uses a programming language such as Solidity to write smart contract code, which can be automatically executed on the blockchain.
(2) Block chain network: the smart contract module needs to interact with the blockchain network in order to execute the smart contract code on the blockchain. Common blockchain networks include ethernet, EOS, TRON, etc.
(3) Intelligent contract library: a smart contract library is a set of functions and interfaces provided for use by developers to write and manage smart contract code. Common intelligent contract libraries include web3.js, truffle, etc.
(4) Deploying a testing module: after the intelligent contract code is written, the intelligent contract code needs to be deployed on a blockchain network and tested to ensure the correctness and the safety of the intelligent contract code.
Through the cooperative work of the above components, the intelligent contract module can realize the function of automatically executing contracts, such as automatic transfer, automatic auction, automatic insurance, and the like. In addition, the smart contracts may enable the development of decentralised applications (DApp) so that users can conduct transactions and services without the need to trust third party institutions.
The file storage module provided by the invention can perform multiple signature verification on the file, and the distributed computing module can perform multiple signature verification on each computing result, so that the security is higher. The novel intelligent contract module not only can automatically execute corresponding operations according to preset conditions and rules, but also can realize the transaction and management functions of digital currency, has wider application range and widens the business mode to form a closed loop from file management to financial management.
The authority setting is strict and reasonable, the authority setting is scientifically managed in a layering manner, the authority setting has audit and tracking functions, the parallelism and the efficiency can be improved through distributed computing, and the intelligent contract module can also realize automatic business logic and rule control.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
