FILE SHARING METHOD, DEVICE, AND SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240330242 titled 'FILE SHARING METHOD, DEVICE, AND SYSTEM
The patent application describes a method, apparatus, and system for sharing files in the field of computers. One implementation involves compressing files into packages, uploading them to a blockchain, and using root hash values to access the shared files efficiently.
- Acquiring files to be shared and uploading compressed file packages on a blockchain
- Generating root hash value based on file names and hash values of compressed packages
- Accessing compressed file packages on a blockchain using the root hash value
- Storing or updating files and sharing root hash value using data structures like binary tree or multi-way tree
- Improving file security by using root hash value and node hash values to access shared files
Potential Applications: - Secure file sharing platforms - Data storage and retrieval systems - Blockchain-based file management tools
Problems Solved: - Excessive network resource burden due to large number of files - Inefficient file uploading and sharing processes - File security and access control issues
Benefits: - Increased efficiency in file sharing and storage - Enhanced security and access control mechanisms - Streamlined file management processes
Commercial Applications: Title: Blockchain File Sharing System for Enhanced Security and Efficiency Description: This technology can be used in cloud storage services, document management systems, and collaborative platforms to improve file sharing and security measures.
Questions about the technology: 1. How does the use of root hash values improve file security in the system? 2. What are the potential drawbacks of compressing files into packages for sharing on a blockchain?
Original Abstract Submitted
the disclosure relates to a method, apparatus and system for sharing files, and mainly relates to the technical field of computers. one specific implementation mode of the method comprises: acquiring files to be shared, and uploading, on a blockchain, formed compressed file packages; generating by calculation a root hash value in accordance with file names of the compressed packages and hash values thereof; and acquiring respective compressed file packages in a blockchain in accordance with the root hash value. the technical problem of an excessive burden of network resources caused by a large number of files is partially overcome by compressing a plurality of files into compressed file packages, and the file uploading and sharing efficiencies are increased by uploading the respective compressed file packages on the blockchain concurrently; the files are stored or updated, and the root hash value is shared by using data structures such as a binary tree structure, a multi-way tree structure, and a dynamic tree structure to acquire, by the root hash value and respective node hash values, the shared files, which improves the security of the files.
