Facial Recognition Authentication Using Wearable ID Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facial recognition systems for authentication are slow and lack adequate security due to the need to compare extracted facial features against all data in a database, often requiring a single level of authentication and delaying the verification process until a subject's face is identified.
Innovation Solution
A method and system that utilize a broadcast device to send an identification code, allowing pre-identification of stored facial data associated with the code, generating and comparing second facial data for rapid authentication, and optionally incorporating gait data for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If facial features are extracted and compared against all database data, then authentication accuracy is maintained, but authentication speed deteriorates
Solution Approach 1:
The system performs preliminary actions by receiving and processing the identification code from the wearable device before the facial recognition process begins. This pre-identification step prepares the system in advance, allowing the facial feature comparison to start immediately with pre-loaded reference data, thus maintaining accuracy while reducing wait time.
2Device complexity
If single-level facial recognition authentication is used, then system simplicity is maintained, but security level deteriorates
Solution Approach 1:
The system merges two distinct authentication methods into a unified process: wearable device identification (first level) and facial recognition verification (second level). This combination creates a multi-factor authentication system that enhances security while maintaining operational simplicity through automated sequential processing.
3Use of energy by moving object
If facial recognition process begins only after face picture is identified, then system resource usage is optimized, but user wait time increases
Solution Approach 1:
The system performs preliminary processing by receiving the identification code from the wearable device before initiating the facial recognition process. This allows the system to prepare reference data and configure processing parameters in advance, so that when the user presents their face, the comparison can begin immediately without delay.

AI summary
Systems and methods for authenticating a broadcast device using facial recognition are herein disclosed. The disclosure includes receiving, from a wearable device, a broadcast signal comprising an identification code of the wearable device; determining, using a processor, whether the identification code is stored within a database; identifying first facial data stored within the database, the first facial data associated with the identification code; generating second facial data; and determining, using the processor, whether the second facial data matches the first facial data. In an implementation, the broadcast device is a Bluetooth low energy device. In a further implementation, the broadcast device comprises the wearable device. In a still further implementation, the disclosure includes detecting gait data and determining whether the gait data matches gait feature data extracted from stored gait data features.
