Authentication System Using Multi-Source Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems are inadequate in preventing fraud as they rely solely on information from the card, allowing malicious third parties to forge cards and evade detection.
Innovation Solution
An authentication system that includes input information acquisition, identification information acquisition, and authentication means to compare input information from a user's terminal with registered information stored on a server, utilizing NFC and image authentication to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication is executed by comparing two pieces of information obtained from the card (card face information and card information from magnetism or electric circuit), then the authentication process is simple, but security is insufficient because forged cards with illegally obtained card information can evade detection
Solution Approach 1:
The patent introduces a new dimension of verification by comparing three distinct pieces of information: card face information (visual), card information from magnetic strip or electric circuit (electronic), and additional verification information (such as hologram or RFID data). This multi-dimensional approach transforms the authentication from a two-dimensional comparison to a three-dimensional verification system, making it significantly harder for forged cards to evade detection while maintaining operational simplicity.
2Device complexity
If only card information is used for authentication, then the authentication system is easy to implement, but it cannot detect forged cards with illegally obtained card information
Solution Approach 1:
The patent segments the authentication process into three distinct information sources: card face information (visual identification), card information from magnetic strip or electric circuit (electronic identification), and additional verification information (such as hologram patterns or RFID data). By dividing the authentication system into multiple independent verification channels, the patent enhances fraud detection capability without significantly increasing overall system complexity, as each segment can be implemented using existing technologies.
3Ease of operation
If card face information is converted into comparable information format, then authentication can be executed, but the conversion process may introduce errors or lose original information characteristics
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms card face information (visual patterns, holograms, or images) into a standardized digital format that can be compared with card information from magnetic strips or electric circuits. This intermediary step uses image recognition and data extraction algorithms to accurately convert visual information without losing critical characteristics, ensuring high comparison accuracy while enabling automated authentication execution.

AI summary
Input information acquisition means (101, 201) of an authentication system (S) acquires input information, which accompanies a card possessed by a user, and has been input from a user terminal through use of reading means (33A) or photographing means (36). Identification information acquisition means (102, 202) acquires identification information that enables identification of the card. Registered information acquisition means (105, 203) acquires registered information, which accompanies the card, and has been registered in a server in association with the identification information in advance. Authentication means (103) executes authentication based on the input information and the registered information.
