Offsite Temperature Screening for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security measures, such as on-site thermal detectors, are inadequate in preventing contamination from individuals carrying diseases, as they require close spatial range and cannot screen access before contamination occurs, posing a risk to building occupants.
Innovation Solution
A system that uses offsite sensors to detect user characteristics, such as temperature, and verifies user identification before access, transmitting notifications to allow or deny access to access-controlled areas, with onsite sensors providing secondary authentication upon entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site thermal detectors are used for access control, then user identification can be verified, but contamination risk increases because screening occurs after entry
Solution Approach 1:
The system performs temperature screening and health verification offsite before the user physically enters the controlled area. Users complete health screenings, temperature checks, and symptom assessments remotely through a mobile application, allowing the system to pre-approve or deny access before the user reaches the building entrance, thereby eliminating post-entry contamination risks
2Object-affected harmful factors
If offsite sensor screening is implemented, then contamination risk is reduced, but system complexity increases
Solution Approach 1:
Users autonomously complete their own health screenings, temperature measurements, and symptom assessments through a mobile application without requiring manual intervention from security personnel or complex automated equipment. The system provides clear instructions and automatically processes the data, minimizing the need for additional hardware and reducing operational complexity
Solution Approach 2:
The mobile application serves multiple functions: it guides users through health screenings, collects temperature data, assesses symptoms, verifies user identity, and communicates access decisions. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated platform, reducing overall system complexity
3Productivity
If pre-entry verification is performed, then access control efficiency is improved, but user convenience may be reduced
Solution Approach 1:
Users independently complete all screening procedures through their personal mobile devices at their own pace, eliminating the need to wait in lines or interact with security personnel. The system processes screenings automatically and provides immediate access decisions, making the process as convenient as using a traditional digital key while maintaining rigorous security protocols

Function Achieved in This Case
This system effectively screens users for temperature-based health conditions before they enter a building, reducing the risk of contamination and improving access control efficiency by allowing pre-entry verification.
Implementation Method 1
offsite sensor data associated with the user and satisfying a temperature threshold
Data Source
AI summary
The present disclosure relates to systems and methods of control access to a controlled-access area. The method includes receiving offsite sensor data, receiving offsite user identification data corresponding to the offsite sensor data, determining that the offsite sensor data satisfies an organizational standard, determining that the offsite user identification data corresponds to an approved user, and transmitting a notification to a user device. The method may also include receiving onsite user information and using the offsite sensor data and the onsite user information to determine if a user is approved for access to an access-controlled area. In some examples, the offsite sensor data may be temperature data associated with a febrile condition of a user attempting to gain access to the controlled-access area.
