Web Service Intermediary for Secure Operator Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote access systems for online services require authentication, are vulnerable to virus attacks, and necessitate trust relationships and special software installations, complicating operator assistance and data sharing without compromising security or network settings.
Innovation Solution
Utilizing an existing web service connection and protocol to enable operators to provide directions and share documents on a visitor's terminal without authentication, using a passive acceptance model that does not allow remote control or data exchange beyond graphical data, thus maintaining security and avoiding software installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote access systems are used to enable operator assistance and screen sharing, then operator guidance capability is improved, but terminal security deteriorates due to authentication requirements and vulnerability to virus attacks
Solution Approach 1:
The patent introduces a server as an intermediary between the operator terminal and visitor terminal. The server hosts a web service that generates unique web service URLs, allowing the operator to share their screen view with the visitor without establishing direct remote access to the visitor's terminal. This mediator approach enables assistance while maintaining terminal security by avoiding direct connections and authentication requirements.
2Ease of operation
If traditional remote desktop services are implemented, then operator control capability is improved, but device complexity increases due to special software installations and trust relationships
Solution Approach 1:
The patent utilizes a standard web browser and web service infrastructure that is universally available across different operating systems and devices. Instead of requiring specialized remote desktop software installations, the system uses web technologies (HTML, JavaScript, WebSocket) that can be accessed through any modern browser, making the solution universally applicable without increasing device complexity.
Solution Approach 2:
The patent replaces traditional mechanical remote desktop protocols with web-based technologies. Instead of using specialized remote access protocols that require software installation and configuration, the system uses web sockets and JavaScript to achieve screen sharing and communication, substituting a complex mechanical system with a lighter web-based approach.
3Productivity
If direct terminal-to-terminal connections are established for assistance, then communication efficiency is improved, but network security deteriorates due to firewall and trust relationship requirements
Solution Approach 1:
The server acts as a mediator that hosts the web service and facilitates communication between operator and visitor. The web service URL generated by the server enables the operator to share their view without creating direct network connections between terminals. This approach maintains network security by avoiding firewall penetration and trust relationship establishment while still enabling efficient communication through the web-based interface.

AI summary
An apparatus comprises a memory and a controller. The controller is configured to identify at least one visitor terminal accessing a web service and to initiate an assistance session. The apparatus further generates a visitor-specific copy of said web service and shares said visitor-specific copy between said at least one visitor terminal and an operator terminal.
