Steganographic Card Encoding for Private Biometric Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card-based transaction verification methods, such as passwords and PINs, are prone to hacking and user forgetfulness, while implementing biometrics on cards is challenging.
Innovation Solution
A steganographically encoded card containing biometric data, such as facial patterns or fingerprints, which is embedded on the card substrate, allowing for secure identity verification through a processor that matches user-provided biometric data with the encoded data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional verification methods (passwords, PINs) are used, then ease of operation is maintained, but security reliability deteriorates due to hacking risks and user forgetfulness
Solution Approach 1:
The patent creates a visual copy of biometric data (facial patterns, fingerprints, or other biometrics) and embeds it within a steganographic pattern on the card. This allows the card to contain verified biometric information in a visual format that can be read by a camera, combining the security of biometrics with the portability of a card.
Solution Approach 2:
The steganographic pattern serves as an intermediary that bridges the gap between physical biometric verification and card-based portability. The pattern encodes biometric data visually, allowing a camera to capture and process the information without requiring direct contact with the user's actual biometric features.
2Reliability
If biometric data is stored on third-party servers, then verification capability is improved, but user privacy and security are worsened due to data exposure risks
Solution Approach 1:
The patent extracts biometric verification capability from centralized servers and embeds it directly into the card itself through steganographic encoding. This eliminates the need to store or transmit biometric data to third-party servers, keeping the verification process local and private.
Solution Approach 2:
The card becomes self-sufficient by containing the encoded biometric data internally. The card can independently provide verification information to authorized devices without requiring external server infrastructure, making the system more private and less vulnerable to centralized data breaches.
3Ease of operation
If biometric information is visibly displayed on the card, then ease of operation is improved for user awareness, but security is worsened due to exposure to unauthorized viewing
Solution Approach 1:
Instead of displaying actual biometric images, the patent creates a steganographic visual copy that encodes biometric data within a pattern that appears ordinary or decorative. The biometric information is present but hidden, allowing user awareness without unauthorized viewing.
Solution Approach 2:
The steganographic pattern has different qualities for different observers: to the naked eye it appears as an ordinary decorative pattern, but to a camera or image-processing system it contains encoded biometric data. This local differentiation of information quality solves the contradiction between visibility and security.
Data Source
AI summary
A card, system, and method for validating a user's identity with card image steganography are provided. The system includes a card, a user device, and a processor. The card comprises a face with a steganographic pattern encrypted onto its substrate. The processor is configured to receive a request associated with the card, recognize the biometric data from the steganographic pattern on the card, and verify the user's identity by matching the user's biometric to the card's biometric.
