Chat File Transfer via MSRP Tunnel and Hidden Access Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
File transfer during online chat sessions poses security risks due to the vulnerability of links, allowing unauthorized access and resource inefficiencies from simultaneous file distribution.
Innovation Solution
Implementing a secure file transfer method using Message Session Relay Protocol (MSRP) tunnels and password-protected links, where the link and password are transmitted invisibly through MSRP, ensuring seamless file delivery while protecting against interception and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If file links are transmitted openly during chat sessions, then file transfer ease is improved, but security is worsened due to vulnerability of links to unauthorized access
Solution Approach 1:
The patent introduces an intermediary mechanism where the messaging application server acts as a mediator between the chat participants. Instead of directly sharing vulnerable file links, the server receives file transfer requests, manages the actual file transmission through controlled channels, and only provides necessary access information to authorized parties. This intermediary role resolves the contradiction by maintaining ease of operation through automated server-mediated transfer while improving security through controlled access management.
2Productivity
If file links are distributed to multiple users simultaneously, then productivity is improved, but resource consumption is worsened due to inefficiencies from simultaneous file distribution
Solution Approach 1:
The patent implements preliminary action by having the messaging application server prepare and manage file transfer operations before actual user downloads occur. The server receives file transfer requests in advance, establishes controlled distribution channels, and coordinates multiple user accesses through a centralized mechanism. This allows the server to optimize resource usage by handling requests sequentially or in coordinated batches rather than simultaneously, improving productivity while reducing resource consumption through efficient resource management.
3Ease of operation
If file transfer is performed through open links, then ease of operation is improved, but harmful factors are worsened due to unauthorized access risks
Solution Approach 1:
The messaging application server serves as a secure intermediary that receives file transfer requests from senders and manages distribution to recipients. Instead of using open vulnerable links, the server establishes controlled communication channels, validates recipient authorization, and manages file transmission securely. This intermediary mechanism maintains ease of operation through automated processes while eliminating harmful factors by preventing unauthorized access through server-side authentication and controlled delivery.

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transferring files securely data are disclosed. In one aspect, a method includes the actions of receiving, by a content management application, a file and a request to provide the file to the second computing device. The actions further include providing, by the content management application and to the first computing device, the link to the file and the password to access the link. The actions further include providing, to the first computing device via the MSRP tunnel, the link to the file and the password to access the link. The actions further include receiving, by the content management application, a request for the file, the link to the file, and the password to access the link. The actions further include providing, to the second computing device, the file.
