Security Inference Module for Trusted User-Based App Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Less technical users face challenges in making informed security decisions about application installations on their devices, particularly when their more technical friends are unavailable for guidance.
Innovation Solution
A security inference module on the computing device identifies candidate applications, trusted users, and their installation activities to determine whether to install the application based on the trusted users' behavior, such as installation rates, settings, and reviews.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users rely on their own judgment for application installation decisions, then they maintain independence and speed in making decisions, but they risk installing harmful applications due to lack of technical knowledge
Solution Approach 1:
The patent introduces a security inference module that acts as an intermediary between the user and the application installation process. This module automatically analyzes trusted users' installation behaviors and security decisions, inferring recommendations without requiring the user to directly consult trusted friends. The module mediates the complex social decision-making process by translating trusted users' actions into actionable security guidance, thereby improving reliability while maintaining ease of operation.
2Reliability
If users consult trusted friends for application installation advice, then they improve security decision accuracy, but they cannot obtain guidance when friends are unavailable
Solution Approach 1:
The security inference module performs preliminary analysis of trusted users' installation behaviors and security decisions in advance, building a knowledge base of security patterns before they are needed. When a user encounters an application installation decision, the module can immediately query this pre-analyzed data and provide recommendations without requiring real-time communication with trusted friends. This eliminates the time loss associated with contacting friends while maintaining the reliability of their expertise.
3Reliability
If users manually analyze application security information, then they make informed decisions, but they lack the technical expertise to effectively evaluate security risks
Solution Approach 1:
The patent implements a system where trusted users' security evaluation capabilities serve themselves automatically. The security inference module monitors and analyzes the installation behaviors and security decisions of trusted users, extracting security patterns and recommendations without requiring those trusted users to actively participate or teach their knowledge. This self-service mechanism transfers security expertise from trusted users to less technical users automatically, improving both reliability and ease of operation simultaneously.

AI summary
Inferring security decisions from trusted users, including: identifying, by a security inference module on a computing device, a candidate application to be installed on the computing device; identifying, by the security inference module, one or more trusted users; identifying, by the security inference module, trusted user installation activity associated with the candidate application; and determining, by the security inference module, whether to install the candidate application in dependence upon the trusted user installation activity associated with the candidate application.
