Door Lock Security Assessment Using Multi-Source Risk Indices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door lock security assessment methods are simplistic and lack accuracy, primarily focusing only on the door lock end, leading to inadequate security evaluation results.
Innovation Solution
A comprehensive door lock security assessment method that involves sending security evaluation instructions to the door lock end for local assessment, obtaining historical behavior data, and combining it with security indices from a control end and a server to determine a comprehensive security assessment result, using formulas to weight and calculate the overall security score based on multiple dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only the door lock end is analyzed for security assessment, then the assessment process is simple, but the accuracy of security assessment results is low
Solution Approach 1:
The security assessment process is divided into three independent segments: door lock end assessment (first security index), control end assessment (third security index), and server-side historical behavior analysis (second security index). Each segment evaluates different aspects of security, and their results are combined to form a comprehensive assessment. This segmentation allows each component to focus on specific security dimensions while maintaining overall system complexity manageable.
Solution Approach 2:
The assessment methodology transitions from a single-dimensional evaluation (only door lock end) to a multi-dimensional evaluation framework that incorporates: 1) local environment security (door lock end), 2) control end security (user terminal), and 3) historical behavior patterns (server-side). This dimensional expansion provides a more comprehensive security picture by evaluating security from multiple perspectives simultaneously.
2Reliability
If multiple security indices from different ends are combined for assessment, then the accuracy of security assessment results is improved, but the device complexity increases
Solution Approach 1:
The server acts as an intermediary that receives security indices from both the door lock end and control end, performs historical behavior analysis, and synthesizes all information to generate the final comprehensive security assessment result. This intermediary approach centralizes the complex integration logic in a dedicated component, preventing the complexity from propagating throughout the entire system.
Solution Approach 2:
The system merges three distinct security evaluation results (first security index from door lock end, second security index from server-side historical analysis, and third security index from control end) into a single comprehensive security assessment result. This merging process integrates multiple security perspectives while presenting a unified output, simplifying the result delivery to users.

AI summary
A door lock security assessment method and a related device. The method comprise: sending a security assessment instruction to a door lock end, so as to trigger the door lock end to perform local security environment assessment to obtain a first security index corresponding to the door lock end; acquiring historical behavior data for the door lock end within a specified time period; performing security assessment analysis on the historical behavior data to obtain a second security index; receiving a third security index, which is sent by a control end; determining a security assessment result of a door lock on the basis of the first security index, the second security index and the third security index; and sending the security assessment result of the door lock to the control end.
