Remote Document Control via Server-Mediated Permission Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies lack secure user permission settings for electronic documents, allowing unauthorized access and compromising document security even when encryption is used.
Innovation Solution
A system utilizing a remote control client APP program on intelligent mobile devices and client devices to set user permissions and manage access to electronic documents, employing identification data to authenticate and control document sharing and viewing permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication software is used to transmit electronic documents, then document sharing becomes convenient, but document security deteriorates because user permission cannot be set and unauthorized access occurs
Solution Approach 1:
A server acts as an intermediary between the intelligent mobile device (owner) and client devices (users). The server stores identification data, verifies permissions, and controls document access. This mediator enables convenient sharing through the server while maintaining security through centralized permission management, resolving the contradiction between ease of sharing and document security.
2Reliability
If encryption software is used to protect electronic documents, then document security is improved, but security deteriorates because the password must be transmitted and revealed using communication software
Solution Approach 1:
The password (first identification data) is extracted from the communication transmission process and stored only on the server. The server verifies permissions using this extracted password without transmitting it to clients. This separation removes the harmful factor of password exposure while maintaining security verification, resolving the contradiction between security protection and password safety.
3Reliability
If user permission settings are implemented through the system, then document security is improved, but device complexity increases due to multiple components and identification data management
Solution Approach 1:
The server performs multiple functions: storing identification data, verifying permissions, controlling document access, and managing sharing requests. The intelligent mobile device and client devices use the same client application interface for both secure document access and communication functions. This multi-functionality reduces overall system complexity while maintaining security through centralized server management.
Data Source
AI summary
A system for remotely controlling a document includes a server, an intelligent mobile device, and a first client device. The server stores a first identification datum corresponding to the intelligent mobile device and at least a second identification datum corresponding to the first client device. The intelligent mobile device and the first client device respectively installed with a remote control client APP program and a first customer client APP program. The intelligent mobile device uses the remote control client APP program to set up a user permission of an electronic document. The intelligent mobile device uses the remote control client APP program to transmit the electronic document to the server according to the second identification datum. The first client device uses the first customer client APP program to download the electronic document from the server and control the electronic document according to the user permission.
