Secure File Distribution via Multi-Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file distribution methods lack secure mechanisms to prevent unauthorized access and interception of files, as they often transmit complete data objects that can be decrypted if intercepted.
Innovation Solution
A system that divides a file into multiple portions, associates each portion with a different recipient's electronic device, and assembles the file only after authenticating the recipient on each device, ensuring secure distribution and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete data object is transmitted as a single file, then transmission simplicity is maintained, but security is compromised as the complete file can be intercepted and decrypted
Solution Approach 1:
The patent divides a data object into multiple discrete data segments, each encrypted separately and stored on different electronic devices. This segmentation ensures that no single device contains the complete decrypted data, preventing unauthorized access even if one device is compromised. The segments are distributed across multiple devices and can be reassembled only through coordinated access to all segments.
2Reliability
If file segments are distributed across multiple devices, then security is improved, but system complexity and authentication requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-distributing encrypted data segments to multiple electronic devices before the actual file access is needed. Each device is pre-configured with its specific segment and the necessary decryption keys. When file access is required, the system coordinates authentication across devices and reassembles the data, eliminating the need for complex real-time operations during actual file access.
3Reliability
If discrete encrypted data objects are transmitted via separate means, then interception risk is reduced, but transmission time and coordination overhead increase
Solution Approach 1:
The system implements feedback mechanisms where each electronic device reports the status of its stored data segment to a central coordinator. The coordinator tracks which segments are available and ready for assembly, and only initiates file reassembly when all necessary segments are confirmed present. This feedback loop prevents unnecessary assembly operations and reduces waiting time by providing real-time visibility into segment availability.

AI summary
Apparatuses, methods, systems, and program products are disclosed for secure file distribution. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to divide a file that is intended for a recipient into a plurality of portions. The code is executable by the processor to associate each of the plurality of portions with a different one of the recipient's electronic devices. The code is executable by the processor to assemble the plurality of portions of the file for the recipient in response to authenticating the recipient on each of the recipient's electronic devices that is associated with a portion of the plurality of portions of the file.
