Chat Room File Sharing with Access Control and Modification Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file sharing technologies lack control over access rights and tracking of file modifications during collaborative tasks, leading to potential misuse and loss of control over shared files.
Innovation Solution
A chat room-based file sharing system that creates a controlled environment for sharing files, allowing users to share files while restricting access rights and tracking modifications through a chat room, ensuring that only authorized users can access, modify, and store the files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If file sharing is enabled through existing technologies, then file accessibility and collaboration are improved, but control over access rights and tracking of file modifications are lost
Solution Approach 1:
The patent introduces a server as an intermediary between file sharers and file recipients. The server manages file storage, controls access rights, and tracks modifications centrally, allowing users to share files while maintaining control through the intermediary system rather than direct peer-to-peer sharing.
Solution Approach 2:
The system implements feedback mechanisms where the server continuously monitors and records file access and modification actions. This feedback loop provides the file owner with information about who accessed the file and what changes were made, enabling ongoing control and accountability.
2Productivity
If file sharing is enabled through existing technologies, then collaboration efficiency is improved, but tracking of file modifications and unauthorized use prevention are worsened
Solution Approach 1:
The server implements continuous feedback by recording all file access and modification events. This creates an audit trail that tracks who accessed the file, when, and what changes were made, preventing information loss about file modification history while enabling efficient collaboration.
Solution Approach 2:
The system creates copies of file metadata and access logs on the server, separate from the actual file content. This copying mechanism preserves information about file modifications without interfering with the collaborative editing process, allowing tracking while maintaining productivity.
3Reliability
If a chat room-based file sharing system is implemented, then control over access rights is improved, but system complexity increases
Solution Approach 1:
The patent merges file sharing functionality with chat room functionality into a single integrated system. The chat room serves as both the communication platform and the file sharing interface, eliminating the need for separate file sharing software and reducing overall system complexity despite enhanced control capabilities.
Solution Approach 2:
The chat room system is designed to perform multiple functions: communication, file sharing, access control management, and modification tracking. This multi-functionality reduces the need for separate specialized systems, managing complexity through consolidation rather than proliferation of components.
Data Source
AI summary
A chat room-based file sharing device includes: a memory; and a processor electrically connected to the memory, wherein the processor receives file sharing request information including information about a target shared file and a shared file recipient, creates a file sharing chat room associated with the target shared file, that is specified by the file sharing request information, and, when the file sharing chat room is rendered on a terminal of the shared file recipient, provides a file object corresponding to the target shared file through the file sharing chat room, wherein the file sharer and the shared file recipient share the target shared file through the file sharing chat room by participating as chat participants in the file sharing chat room.
