Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In remote desktop (RD) services, concurrent user sessions can lead to confusion and security issues when using RD scanning, as users may select and access image capturing devices (ICDs) connected to other users' client computers.

Innovation Solution

The implementation of a scanner redirection method in an RD computer system, where each client computer maintains separate lists of connected ICDs accessible only to its respective RD session, preventing users from selecting and accessing ICDs connected to other users' computers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple users concurrently access the same endpoint with RD scanning enabled, then scanner redirection functionality is provided to all users, but users can mistakenly select or access ICDs connected to other users' client computers causing confusion and security issues

Engineering Contradiction:

Improvescanner redirection functionalityVSAvoidICD access confusion and security risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the ICD resource pool by creating separate ICD lists for each RD session. Each session receives only the ICDs connected to its own client computer, preventing access to other users' ICDs. This segmentation resolves the contradiction by maintaining scanner redirection functionality while eliminating cross-user access confusion and security risks.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If all connected ICDs are presented to each user session, then complete ICD availability is achieved, but user confusion increases when multiple users have ICDs with the same model or name

Engineering Contradiction:

ImproveICD availabilityVSAvoidICD selection clarity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by customizing the ICD list content for each RD session based on its specific client computer's connected devices. Each session receives a tailored list containing only locally connected ICDs, eliminating confusion from duplicate ICD names across different users while maintaining complete availability of each user's own ICDs.

Inventive Principle:

Principle #3Local quality

AI summary

A scanner redirection method for a remote desktop computer system, wherein the remote desktop computer system includes a plurality of client computers and a remote computer, and wherein the remote computer concurrently has a first remote desktop session with a first client computer and a second remote desktop session with a second client computer, the scanner redirection method comprising: creating a first list of image capturing devices that are connected to the first client computer; creating a second list of image capturing devices that are connected to the second client computer; in response to receiving from the first client computer a selection of a first image capturing device from the first list, transmitting to the first client computer, an identifier (ID) of the first image capturing device; and after transmitting the ID, receiving from the first client computer, an image created by the first image capturing device.
