Facial Recognition False Positive Reduction via Contextual Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial recognition systems in public events face challenges in accurately verifying the presence of individuals due to high rates of false positives, particularly in environments where contextual and location data analysis is resource-intensive and inaccurate.
Innovation Solution
An apparatus and method that combines contextual and location data with facial recognition analytics, using a processor to receive and compare image data with user device contextual data, employing two-dimensional, three-dimensional facial recognition, or convolutional neural networks to accurately identify individuals in images, thereby reducing false positives by determining potential user presence before facial recognition analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If facial recognition alone is used to identify people in pictures, then identification capability is provided, but false positives occur and accuracy deteriorates
Solution Approach 1:
The patent combines facial recognition analysis with contextual data verification (location data, timestamp, device information) to create a multi-factor identification system. This merging of multiple verification methods reduces false positives while maintaining identification capability, directly resolving the contradiction between identification accuracy and false positive rate.
Solution Approach 2:
The system performs preliminary verification by checking contextual data (location, timestamp, device context) before finalizing facial recognition identification. This preliminary action filters out potential false positives early in the process, improving overall identification reliability without sacrificing accuracy.
2Reliability
If contextual and location data analysis is performed to verify presence, then false positives are reduced, but processing resources are consumed
Solution Approach 1:
The system applies contextual verification selectively - performing full contextual data analysis only when facial recognition detects a potential match, rather than analyzing all images uniformly. This partial action approach reduces overall processing resources while maintaining false positive reduction where it matters most.
Solution Approach 2:
The system performs preliminary filtering using low-resource contextual checks (timestamp, location) before committing to more resource-intensive facial recognition analysis. This preliminary action reduces the number of images requiring full processing, thereby reducing overall resource consumption while maintaining reliability.
3Productivity
If contextual data verification is performed before facial recognition, then processing load is reduced, but system complexity increases
Solution Approach 1:
The system performs preliminary contextual verification (checking timestamp, location, device information) before initiating facial recognition analysis. This preliminary action filters out images that cannot possibly contain the target person, reducing processing load and improving productivity without requiring complex system architecture changes.
Solution Approach 2:
The verification process is segmented into distinct stages: contextual data checking, facial recognition analysis, and final verification. This segmentation allows each component to operate independently and efficiently, managing system complexity while improving overall processing productivity through modular architecture.
Data Source
AI summary
An apparatus can include a memory, a communication interface, and a processor. The processor is configured to receive image data from an imaging device and first contextual data associated with the image data. The image data includes at least one image of a field of view. The processor is also configured to receive second contextual data associated with a user of a user device. The second contextual data is generated in response to the user device receiving a wireless signal sent by an antenna operably coupled to the imaging device. The processor is further configured to determine a potential presence of the user in the image data based on comparing the first contextual data with the second contextual data, analyze the image data to identify the user in the image data, and send the image data to the user.
