Solution Overview
Problem
Current secure data transmission systems face challenges in managing file transfers, including resource inefficiency and incomplete file transmission verification, which can compromise network security.
Innovation Solution
A secure data transfer device and method that breaks down digital files into packets for individual or sequential verification, using a verification module with a buffer memory to ensure complete file integrity before transferring, and includes a second file management module for organized storage and access, preventing unauthorized access by malicious elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If files are transferred in parallel through a secure transfer device, then transfer speed is improved, but resource consumption increases due to multiple description tables
Solution Approach 1:
The patent segments the file transfer process into distinct phases: a first phase where files are transferred to a secure transfer device and stored in a first file management module, and a second phase where verified files are transferred to a second file management module. This segmentation allows parallel transfers to be managed efficiently without requiring multiple simultaneous description tables, thus maintaining high transfer speed while reducing resource consumption.
Solution Approach 2:
The patent applies preliminary action by completing the entire transfer of a file to the secure transfer device and performing verification before initiating transfer to the destination system. This ensures that file integrity is confirmed upfront, eliminating the need for complex parallel tracking mechanisms and reducing resource consumption while maintaining productivity.
2Reliability
If verification is performed on transferred files, then security is improved, but transfer time increases due to sequential processing
Solution Approach 1:
The patent segments verification into two distinct stages: first verification of files transferred to the secure transfer device, and second verification of files transferred to the destination system. This segmentation allows for efficient resource management and parallel processing opportunities, maintaining high security standards while minimizing the time impact on overall transfer operations.
Solution Approach 2:
The patent ensures continuity of useful action by implementing a seamless two-phase transfer process where verification occurs during natural transition points rather than as separate interruptive steps. Files are continuously moved through the system with verification integrated into the transfer flow, maintaining security without significant time loss.
3Measurement precision
If a central storage element tracks file transmission completion, then file management accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments file tracking responsibilities between two distinct file management modules: the first file management module tracks files incoming to the secure transfer device, and the second file management module tracks files outgoing to destination systems. This segmentation provides precise tracking at each stage without requiring a single complex centralized tracking system, thus maintaining measurement precision while reducing overall system complexity.

AI summary
The invention relates to a method for the secure transfer of a digital file from a first computerised system to at least one second computerised system, said method comprising the following steps: writing (110) the digital file on a first file-management module of a secure transfer device, transferring (120) said digital file to an internal verification module of the secure transfer device, verifying (130) at least one portion of the transferred digital file in the verification module, and transferring (140) the at least partially verified digital file to a second file-management module of the secure transfer device according to the result of said verification, in order to allow the file to be read by the at least one second computerised system according to the result of said verification. The invention also relates to a secure transfer device capable of implementing such a transfer method.
