Authentication Chip with Optical Verification for Card Forgery Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for cards, such as magnetic cards and IC cards, are vulnerable to forgery and do not provide adequate security, especially when personal identification numbers are used, and existing biometric techniques are inconvenient and not foolproof.
Innovation Solution
Incorporating an authentication verifying chip with unique features like metal granules, fiber pieces, or embossed holograms, combined with a certifying chip that uses encryption and decryption to verify the card's authenticity, allowing for secure identification without relying on human judgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic stripes or IC cards are used for card information storage, then card functionality is enabled, but security against forgery is insufficient
Solution Approach 1:
The patent combines multiple authentication elements (magnetic stripe, IC chip, and optical verification chip with metal granules/fibers) into a single card structure. The optical verification chip contains metal granules or fibers arranged in a specific pattern that is difficult to replicate, creating a composite authentication system that leverages the strengths of different materials and technologies to resist forgery while maintaining card functionality.
2Ease of operation
If personal identification numbers are used for authentication, then card usage is enabled, but security is compromised
Solution Approach 1:
The patent introduces an optical verification chip as an intermediary authentication mechanism between the user and the card verification system. This chip contains metal granules or fibers arranged in a unique pattern that serves as a physical intermediary for verification, replacing or supplementing the vulnerable PIN-based system while maintaining ease of card usage.
3Reliability
If biometric techniques are used for authentication, then security is improved, but convenience and reliability are reduced
Solution Approach 1:
The patent uses a disposable optical verification chip containing metal granules or fibers that can be easily manufactured and integrated into cards. This approach provides strong security through unique physical patterns while maintaining convenience, as the verification process is automated and does not require complex biometric scanning or user interaction.
4Ease of operation
If authentication verification is performed without host server, then convenience is improved, but complexity of authentication system increases
Solution Approach 1:
The optical verification chip is designed to be self-verifying through its unique physical structure (metal granule or fiber arrangement). The card itself contains all necessary authentication elements, allowing verification without requiring constant communication with a host server. This self-service capability improves convenience while the standardized chip design keeps system complexity manageable.

AI summary
It is possible to prevent use of a forged card. An authentication chip describing information which cannot be copied or difficult to be copied is attached to a card and a card processing device includes a card authentication processing device. The information described in the authentication chip is degitized and encrypted to obtain encrypted data, which is described on an authentication certifying chip. The authentication certifying chip is attached to the card. The authentication certifying chip checks the validity of the authentication chip. Before a specific operation such as entry of a password is started, it is judged whether the card is true so as to exclude a forged card.
