Print Gateway Server Mediator for Remote Desktop Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote desktop printing systems face security risks due to direct communication between the remote desktop server and the printer, which can lead to potential attacks from malicious programs.
Innovation Solution
A printing system that includes a location registration equipment for user authentication, a remote desktop server for operating office terminals, and a printing device that transmits location information and printing data through a network, ensuring that the printer and client terminal do not communicate directly, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote desktop server and printer communicate directly, then printing functionality is achieved, but security risks increase due to potential attacks from malicious programs
Solution Approach 1:
The patent introduces a print gateway server as an intermediary component between the remote desktop server and the printer. The print gateway server receives printing requests from the remote desktop server, processes them through location information matching, and forwards them to the appropriate printer. This mediator architecture prevents direct communication between the remote desktop server and printer, thereby blocking potential attack paths while maintaining printing functionality through the controlled gateway interface.
2Reliability
If location information is added to printing data through a gateway server, then security is enhanced, but system complexity increases
Solution Approach 1:
The print gateway server is designed to perform multiple functions within a single system component: it acts as a security gateway, a location information manager, a request router, and a communication bridge. By consolidating these functions into one multi-functional server, the patent reduces overall system complexity compared to having separate dedicated components for each function, while still achieving enhanced security through location-based access control.
3Reliability
If direct communication is prevented between printer and client terminal, then security is improved, but communication efficiency may decrease
Solution Approach 1:
The system performs preliminary actions by pre-registering location information for various workspaces and pre-establishing the print gateway server's routing rules before actual printing operations. When a printing request arrives, the gateway server can quickly match the client's location information against pre-stored data and forward the request accordingly, minimizing processing delays. This preliminary preparation maintains security while reducing the impact on printing speed.
