Access Control System with Health Risk Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems do not account for real-time health risks of individuals, allowing potentially contagious persons to enter communal areas and potentially spread diseases, leading to health risks and business disruptions.
Innovation Solution
A method and system that measure characteristics such as body temperature, heart rate, and mask usage to classify individuals as high-risk, denying access to communal areas while allowing access to private areas, using sensors, wearable technology, and machine learning algorithms to update access rights dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control systems are used that only check credentials, then access management is simple and straightforward, but real-time health risks cannot be detected and potentially contagious persons can enter communal areas
Solution Approach 1:
The patent combines traditional credential-based access control with real-time health monitoring systems. The access control system is merged with temperature sensors, facial recognition cameras, and wearable device integration to create a unified system that simultaneously verifies identity and assesses health status, thereby improving reliability without requiring entirely separate systems
Solution Approach 2:
The access control system is transformed into a multi-functional system that performs credential verification, health screening, temperature monitoring, and risk assessment all through a single integrated platform. This allows the system to serve multiple purposes - security access and public health protection - addressing the complexity concern while significantly improving health safety
2Reliability
If access rights are updated in real-time based on health status, then contagious persons can be isolated promptly, but the system requires continuous monitoring and dynamic updates
Solution Approach 1:
The system implements continuous feedback loops where health data from sensors and wearables is constantly monitored, analyzed, and used to dynamically update access rights. When a person's health status changes (e.g., temperature exceeds threshold), the system automatically receives feedback and adjusts their access permissions in real-time, enabling prompt isolation without manual intervention
Solution Approach 2:
The system performs preliminary health screening and risk assessment before granting access to communal areas. By proactively identifying potential health risks through pre-entry temperature checks and health data analysis, the system prevents contagious persons from entering high-risk zones in the first place, rather than reacting after infection occurs
3Measurement precision
If multiple characteristics are measured to classify high-risk persons, then classification accuracy improves, but measurement complexity and processing time increase
Solution Approach 1:
The system implements a tiered measurement approach where essential characteristics (such as temperature and basic credential verification) are measured for all persons to enable quick initial assessment. More comprehensive measurements (detailed health metrics, multiple biometric checks) are performed only on individuals who trigger risk thresholds or show concerning symptoms, thereby maintaining high classification accuracy while minimizing average processing time for the overall population

Function Achieved in This Case
Effectively prevents the spread of infectious diseases by restricting high-risk individuals from communal areas while allowing them to isolate in private spaces, reducing health risks and business disruptions.

AI summary
A method of controlling access of a person (101) to an area that is accessed via an access point having an associated set of access rights, the method including: measuring a characteristic of a person; and based at least in part on the measured characteristic, classifying the person (101) as being in a high risk category of persons, wherein the associated set of access rights of the access point deny permission for the high risk category of persons to access the area.
