Solution Overview

Problem

Users face difficulty in selecting the most secure communication service for point-to-point communication over a network due to lack of knowledge about the security levels provided by different communication applications on their client devices, leading to potential information interception or manipulation.

Innovation Solution

A system and method that automatically selects the communication application with the highest security level from available options on client devices to establish a secure communication link, allowing users to choose based on indicated security levels and enabling secure communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manually select communication applications from multiple available options, then they can choose communication services, but users cannot identify which application provides the highest security level due to lack of knowledge about security levels

Engineering Contradiction:

Improvecommunication securityVSAvoidapplication selection

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables automatic selection of the most secure communication application without requiring user knowledge of security levels. The client device autonomously evaluates available communication applications, compares their security levels, and selects the highest-security option, making the system self-serve the security selection function.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides feedback to users about the security level of the selected communication application. This feedback mechanism informs users about the security characteristics of the automatically selected application, enabling them to make informed decisions while maintaining automated selection processes.

Inventive Principle:

Principle #23Feedback

2Reliability

If the system automatically selects the communication application with the highest security level, then communication security is maximized, but the system complexity increases due to automatic selection logic

Engineering Contradiction:

Improvecommunication securityVSAvoidautomatic selection mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The client device incorporates an automatic selection mechanism that autonomously evaluates and selects communication applications based on their security levels. This self-service capability maximizes security without requiring manual user intervention, though it does increase device complexity through the automated evaluation and selection logic.

Inventive Principle:

Principle #25Self-service
