Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facial recognition systems are vulnerable to defeat by sophisticated face-altering technologies such as masks and prosthetics, leading to misidentification, resource wastage, and potential illegal activities.
Innovation Solution
A detection platform that identifies facial areas and measures characteristics like temperature and moisture levels to determine if the appearance is altered by face-altering technology, selectively performing facial recognition only when the appearance is likely not altered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition is performed on all individuals, then authentication coverage is maximized, but computing resources are wasted on face-altering technologies and misidentification occurs
Solution Approach 1:
The system performs preliminary detection of face-altering technologies using temperature sensing before conducting facial recognition. By detecting temperature anomalies in the facial area that indicate masks or prosthetics, the system prevents unnecessary facial recognition processing, thereby avoiding resource waste and misidentification while maintaining accurate authentication for legitimate users.
2Ease of operation
If facial recognition is performed on individuals with altered appearances, then authentication attempts are processed, but misidentification and security vulnerabilities occur
Solution Approach 1:
Temperature sensing acts as an intermediary detection mechanism between the individual's appearance and the facial recognition system. By measuring temperature in the facial area, the system identifies face-altering technologies without requiring direct visual analysis of the altered features, thus maintaining accurate identification while preventing security vulnerabilities.
3Measurement precision
If temperature sensing is added to detect face-altering technologies, then detection capability improves, but device complexity increases
Solution Approach 1:
The temperature sensing component serves multiple functions: detecting face-altering technologies, validating authentication attempts, and preventing security vulnerabilities. By using a single sensing mechanism for multiple detection purposes, the system improves measurement precision without proportionally increasing device complexity.

Data Source
AI summary
A device may select an individual that is a candidate for authentication by facial recognition. The device may identify a facial area of the individual and an area of exposed skin of the individual. The device may obtain a first temperature associated with the facial area of the individual and a second temperature associated with the area of exposed skin of the individual. The device may determine, based on the first temperature and the second temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology. The device may selectively perform facial recognition on the facial area of the individual based on whether the appearance of the facial area of the individual is likely altered by the face-altering technology.
