Biometric Card Authentication Using Invisible Code Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information recording cards, such as IC cards, lack effective security measures to protect biometric information and ensure secure user authentication, particularly against unauthorized use.
Innovation Solution
The card incorporates an invisible code section with encoded biometric information, a memory for encrypted data, and a display section, utilizing biometric authentication to securely verify user identity and update displayed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric information is stored in visible form on the card, then user verification is convenient, but security against unauthorized use deteriorates
Solution Approach 1:
The patent applies invisible ink technology that changes optical properties to hide biometric information. The biometric data is printed using invisible ink that cannot be seen under normal conditions but can be detected by specific devices, thus preventing unauthorized viewing while enabling legitimate verification through appropriate equipment.
Solution Approach 2:
The patent introduces an intermediary verification system where a card reading device acts as a mediator between the card and the verification system. The device reads the invisible biometric information and performs verification, so users don't need to directly view or handle the sensitive biometric data, enhancing security while maintaining convenience.
2Reliability
If biometric information is concealed in invisible form, then security against unauthorized use is improved, but ease of verification deteriorates
Solution Approach 1:
The card reading device serves as an intermediary that automatically handles the complex process of reading and verifying invisible biometric information. Users simply present their card and biometric data (fingerprint, facial recognition), and the system automatically completes verification without requiring users to understand or interact with the invisible information directly.
Solution Approach 2:
The system implements self-service verification where the card and biometric data work together automatically. The invisible biometric information on the card is automatically read and verified against the user's live biometric data by the reading device, eliminating the need for manual verification steps and maintaining user convenience despite the concealed information format.
3Ease of operation
If traditional visible authentication methods are used, then ease of operation is maintained, but security measures deteriorate
Solution Approach 1:
The patent replaces visible authentication elements with invisible ink printing of biometric information. This maintains the simple card-presentation interaction while dramatically improving security by making the authentication data invisible to unauthorized persons, thus preventing spoofing and unauthorized use that plague visible authentication methods.
Solution Approach 2:
The patent replaces traditional mechanical or visual authentication systems with an optical detection system. Instead of relying on visible patterns, magnetic strips, or physical tokens that can be seen and copied, the system uses invisible ink with specific optical properties that require specialized reading devices, substituting a more secure detection mechanism while maintaining user convenience.

AI summary
A card includes an invisible code section in which a biometric code obtained by encoding the biometric information of a user using a predetermined encoding process is recorded in an invisible manner, a memory that stores encrypted information encrypted using the biometric information, and a display section that displays reference information referenced by the user when using the card.
