Biometric-Linked Image Processing Circuitry for User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for imaging devices do not reliably ensure that the user who unlocked the device is the same user using it, and methods for verifying image authenticity are vulnerable to manipulation, as metadata can be easily forged.
Innovation Solution
An image processing circuitry and method that obtain biometric feature data from users, such as through retina or iris scans, and associate this data with image data to verify the user's authenticity, using encryption and watermarking to secure the image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (e.g., fingerprint sensor) are used to unlock the device, then the user can access the imaging device, but it cannot ensure that the same user who unlocked the device is the user using the device
Solution Approach 1:
The system captures biometric data (retina, iris, or fingerprint) in advance during the unlocking process and stores it temporarily. This preliminary capture of authentication data allows the system to verify user identity continuously during image capture without requiring repeated authentication actions, ensuring the same user operates the device throughout the imaging process.
Solution Approach 2:
The patent introduces biometric data as an intermediary element that mediates between the user and the imaging device. By using biometric features (retina, iris, or fingerprint) as the intermediary authentication mechanism, the system creates a reliable link between the user's physical identity and the device operations, preventing unauthorized use even after initial unlocking.
2Reliability
If metadata is added to image data to indicate position and time for authenticity verification, then image manipulation can be recognized, but the metadata can be easily forged
Solution Approach 1:
The patent merges biometric authentication data with image metadata into a unified authentication package. Instead of relying solely on separate metadata fields that can be forged, the system combines multiple authentication elements (biometric data, position, time, device information) into an integrated verification system, making forgery significantly more difficult as all elements must be simultaneously replicated.
Solution Approach 2:
The authentication system uses a composite approach by combining multiple types of data (biometric features, geolocation, timestamp, device identifiers) into a composite authentication record. This composite structure resembles a multi-layered security system where each layer provides additional verification, and the combination makes the overall system resistant to forgery attacks that might succeed against individual elements.
3Reliability
If biometric feature data is obtained and associated with image data for user verification, then user authenticity can be verified, but the system complexity increases
Solution Approach 1:
The patent implements a universal biometric authentication system that can handle multiple biometric modalities (retina scan, iris scan, fingerprint recognition) through a single integrated framework. This multi-functional approach allows the system to adapt to different authentication requirements and hardware configurations without requiring separate processing systems for each biometric type, thereby managing complexity while maintaining high verification accuracy.
