Image Authentication Using Wearable ID for Spoof Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems are vulnerable to spoofing and impersonation, particularly when biometric information is used, as they do not effectively differentiate between the intended user and an impersonator.
Innovation Solution
An information processing system that associates and registers biometric identification information with wearing item identification information, allowing for verification and spoofing determination using captured images, thereby distinguishing between the intended user and potential impersonators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric information is used for authentication, then identification accuracy is improved, but vulnerability to spoofing and impersonation increases
Solution Approach 1:
The patent introduces wearing item identification information as an intermediary element between the biometric information and the authentication decision. This mediator (wearing item) serves as an additional verification layer that must be present alongside the biometric data, thereby preventing spoofing attacks where only biometric information is compromised. The wearing item acts as a physical token that the legitimate user possesses but an impersonator would not have.
Solution Approach 2:
The authentication system combines multiple types of information (biometric identification information + wearing item identification information) into a composite authentication mechanism. This composite approach merges the uniqueness of biometric data with the physical possession verification of wearing items, creating a more robust authentication system that leverages the strengths of both methods while mitigating their individual weaknesses.
2Reliability
If multiple authentication methods are combined, then authentication reliability is improved, but system complexity increases
Solution Approach 1:
The patent designs the authentication system with multi-functionality by using a single image capture device that simultaneously extracts both biometric information and wearing item identification information. This universal approach allows one component (the imaging device) to perform multiple functions (capturing facial features and wearing item details), thereby reducing the need for separate dedicated devices for each authentication method and simplifying the overall system architecture.
Solution Approach 2:
The system merges the authentication process by combining biometric verification and wearing item verification into a single integrated workflow. Both types of information are extracted from the same captured image and processed together in one authentication decision, eliminating the need for separate authentication stages and reducing system complexity while maintaining enhanced security.
3Measurement precision
If high-quality images are required for biometric verification, then verification accuracy is improved, but processing load and facility costs increase
Solution Approach 1:
The patent applies partial action by extracting only the specific features needed from the captured image - namely, biometric identification information and wearing item identification information. Rather than requiring full high-quality image processing, the system selectively extracts relevant data elements, reducing the processing burden while maintaining verification accuracy for the essential authentication parameters.
Solution Approach 2:
The system segments the image processing task by separating the extraction of biometric information from wearing item information. This segmentation allows each type of information to be processed independently using optimized algorithms tailored to its specific requirements, thereby reducing the overall processing load compared to processing the entire image at high resolution for both purposes simultaneously.

AI summary
An information processing system includes: a registration unit that associates and registers biometric identification information capable of identifying a living body, biometric information on a predetermined part of the living body, and wearing item identification information presented by a wearing item worn by the living body, the wearing item identification information being capturable in an image; an acquisition unit that acquires a captured image obtained by capturing the living body wearing the wearing item; a verification unit that verifies the living body by using the wearing item identification information included in the captured image; and a spoofing determination unit that determines whether or not a body other than the living body is impersonating the living body, by using an image of the predetermined part of the living body included in the captured image, in response to a predetermined condition being satisfied.
