Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of determining the overall security state of a mobile terminal relies heavily on user experience, leading to low accuracy and reduced user experience due to the lack of objective assessment methods.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user experience is used to determine overall security state, then the method is simple and easy to operate, but the accuracy of security state determination is low
Solution Approach 1:
The patent segments the overall security state determination into multiple key indicators (e.g., malicious software, junk files, software running state, system vulnerabilities). Each indicator is assessed separately through detection software, and then aggregated to form the overall security state. This segmentation allows for more precise measurement while maintaining ease of operation through automated aggregation.
Solution Approach 2:
The patent introduces an intermediary assessment mechanism that objectively evaluates key indicators through detection software. This intermediary layer bridges the gap between simple user experience and accurate security state determination by providing automated, standardized assessment of multiple indicators, thereby improving accuracy without complicating user interaction.
2Measurement precision
If multiple key indicators are assessed with weight values, then the accuracy of overall security state assessment is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining weight values for each key indicator and establishing assessment policies before actual security assessment. This preparation work is done in advance, so that during runtime, the system only needs to collect indicator data and perform straightforward calculations, improving accuracy without significantly increasing operational complexity.
Solution Approach 2:
The patent uses parameter changes by assigning different weight values to different key indicators based on their importance. This allows the system to dynamically adjust the influence of each indicator on the overall security state assessment, improving measurement precision while maintaining manageable system complexity through structured parameter management.
