Digital Key and Box Authentication for Secure Network Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for data sharing via USB flash disks are inefficient due to distance limitations, require redundant data transfer, lead to version control issues, and compromise security with potential interception and unauthorized access in cloud-based storage.
Innovation Solution
A security information sharing system utilizing a digital key and digital box for secure data transmission over Internet or Local Area Network, eliminating the need for usernames and passwords, and ensuring encrypted data access through a verification code and decoding program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If USB flash disk is used for data transfer between computers, then data can be shared between devices, but data transfer efficiency is reduced by 50% due to two-stage copy in and copy out process
Solution Approach 1:
The patent extracts the data directly from the source computer and transmits it via network to the destination computer, eliminating the intermediate USB flash disk storage step. This direct network transmission approach removes the redundant copy-in-and-copy-out process, thereby improving data transfer efficiency and reducing time loss.
2Ease of operation
If cloud-based remote data storage and sharing is used, then data can be accessed remotely, but security is compromised as digital packets may be intercepted
Solution Approach 1:
The patent introduces a digital key as an intermediary authentication mechanism between the user and the cloud storage system. The digital key contains verification codes that mediate the authentication process, ensuring that only authorized users can access or transmit data, thereby maintaining security while enabling remote access.
3Adaptability or versatility
If data is stored in plain codes in cloud storage, then data can be accessed by authorized users, but individual privacy is lost to unauthorized access
Solution Approach 1:
The patent applies local quality by encrypting data with unique verification codes specific to each user's digital key. Each user's data is protected by their own local encryption key stored in their digital key, ensuring that even if data is accessible remotely, only the authorized user with their specific digital key can decrypt and access it, preventing unauthorized access.
4Productivity
If USB flash disk is used for data sharing, then data can be transferred between computers, but version control becomes difficult when data is duplicated multiply
Solution Approach 1:
The patent implements a feedback mechanism where the cloud storage server maintains centralized version control of all data files. When users upload, modify, or share data, the server receives feedback about these changes, updates the master version, and notifies relevant users. This eliminates version control problems by providing real-time feedback and centralized management of data versions across all users.
