File Distribution System Using Segmentation for Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file distribution methods face challenges in data security due to the high processing power required for encryption, increased file size, and complexity of encryption software and keys, which can be cumbersome and expensive.
Innovation Solution
A file distribution system and method that divides a file into multiple portions and distributes them across separate storage devices, providing security without encryption by scattering contiguous data bits, allowing only the file source to reassemble the file using distribution information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is used to protect stored files, then data security is improved, but processing power requirements increase significantly
Solution Approach 1:
The patent divides a file into multiple portions and distributes them across separate storage devices. This segmentation approach provides security without requiring encryption processing power, as the file cannot be accessed unless all portions are retrieved and reassembled.
2Reliability
If encryption is used to protect stored files, then data security is improved, but file size increases
Solution Approach 1:
The patent segments the file into multiple portions distributed across different storage devices. This segmentation provides security equivalent to encryption without adding the overhead of encryption algorithms, thereby avoiding file size expansion.
3Reliability
If highly secure encryption is used, then data security is improved, but processing time increases significantly
Solution Approach 1:
The patent uses file segmentation distributed across multiple storage devices, eliminating the need for time-consuming encryption and decryption operations. The security is achieved through distribution rather than computational complexity.
4Reliability
If encryption is used to protect stored files, then data security is improved, but system complexity increases due to keys and software
Solution Approach 1:
The patent simplifies the security system by dividing the file into portions and distributing them across storage devices. This eliminates the complexity of encryption keys, encryption software, and key management systems while maintaining security through physical distribution.
Data Source
AI summary
A file distribution system is provided. The file distribution system includes a communication interface configured to communicate with a plurality of storage devices, to receive a file from a file source, and to transfer two or more file portions to two or more storage devices of the plurality of storage devices. The file distribution system further includes a processing system coupled to the communication interface, with the processing system being configured to receive the file from the communication interface, divide at least part of the file into the two or more file portions, and distribute the two or more file portions to the two or more storage devices through the communication interface. The two or more storage devices correspond to the two or more file portions. Each storage device of the two or more storage devices is separate from all other storage devices of the two or more storage devices.
