BIM-Based Security Analysis Engine for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems are cumbersome to set up and configure, especially when dealing with large numbers of sensors and varying security levels, leading to potential human errors and missed threats such as weak partitions and improper authentication levels.
Innovation Solution
A security system that utilizes a building information model (BIM) and an analysis engine to identify potential threats by comparing access control configurations with physical layouts, applying rules like physical risk, walkway restriction, and authentication versus card holder ratio to automatically flag and suggest mitigation for logical and physical security weaknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of security systems with large numbers of sensors and different security levels is used, then system setup time and complexity increase, but human errors and missed threats increase
Solution Approach 1:
The system performs self-configuration by automatically importing sensor locations and building geometry from BIM models, eliminating the need for manual configuration and reducing human errors in security system setup
Solution Approach 2:
The system pre-configures security parameters and threat detection rules based on imported BIM data before actual security operations begin, ensuring accurate initial setup without manual intervention
2Reliability
If comprehensive sensor coverage is implemented to detect all potential threats, then security coverage improves, but system cost and complexity increase
Solution Approach 1:
The system assigns different security levels and sensor types to different zones based on their specific risk profiles and functional requirements, optimizing sensor placement and types for each local area rather than uniform coverage
Solution Approach 2:
The system implements threat detection at multiple levels of detail, focusing comprehensive analysis on high-risk areas identified through BIM-based spatial analysis while using simpler detection methods in lower-risk zones
3Measurement precision
If manual analysis of security configurations is performed to identify threats, then detection thoroughness improves, but analysis time and productivity decrease
Solution Approach 1:
The system replaces manual analytical processes with automated computational algorithms that analyze BIM models and sensor configurations, achieving both high precision in threat identification and rapid processing speeds
Solution Approach 2:
The system introduces an automated analysis engine as an intermediary between raw security configuration data and human decision-makers, performing thorough threat analysis automatically and presenting results for human review

AI summary
An apparatus including a building information model (BIM) of a secured area having a plurality of different portions, the BIM embodied in a memory, a processor that identifies portions of the secured area having different levels of security and a processor that alerts a user of a security weakness based upon an interaction between the security levels and physical characteristics of the secured area defined by the BIM.
