Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart card technologies, particularly contactless smart cards, face inefficiencies and security concerns due to complex fingerprint identification processes that can lead to card damage and unauthorized transactions, especially in situations requiring high-security access or large transactions where legitimate users cannot verify operations personally.
Innovation Solution
A method and device that integrate fingerprint identification technology into a contactless smart card chip, allowing activation of the fingerprint verification process based on a conditional value such as transaction amount or access level, ensuring secure and efficient transactions by determining whether to activate fingerprint verification based on these conditions, using a control unit, induction unit, wireless communication unit, fingerprint acquisition unit, and fingerprint identification unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint identification process is always activated for high-security transactions, then security is improved, but card damage increases and usability deteriorates
Solution Approach 1:
The patent implements dynamic activation of fingerprint identification based on transaction conditions. The system automatically adjusts whether to require fingerprint verification depending on the transaction amount threshold, making the security mechanism adaptive rather than static. This resolves the contradiction by enabling high security when needed (large transactions) while maintaining ease of use for routine operations.
Solution Approach 2:
The patent changes the parameter of security verification activation from a fixed state to a variable state based on transaction parameters. By setting conditional thresholds for transaction amounts, the system dynamically adjusts the security level required, thereby improving usability for small transactions while maintaining strong security for large transactions.
2Reliability
If fingerprint identification process is always activated, then security is improved, but processing time increases
Solution Approach 1:
The system dynamically determines whether to activate fingerprint verification based on real-time assessment of transaction conditions. For transactions below the threshold amount, the system skips fingerprint verification entirely, reducing processing time. For transactions above the threshold, fingerprint verification is activated to ensure security, thereby optimizing the balance between security and processing efficiency.
Solution Approach 2:
The patent applies partial action by selectively activating fingerprint identification only when necessary (for transactions exceeding the threshold). Instead of always performing full fingerprint verification, the system applies the security measure partially - only to the extent required by the transaction conditions - thereby reducing unnecessary processing time while maintaining adequate security.
3Reliability
If fingerprint identification is integrated into smart card chip, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the fingerprint identification functionality directly into the smart card chip, integrating multiple security functions into a single device. This combination reduces the need for separate external verification systems and simplifies the overall architecture while enhancing security capabilities through the unified design.
4Reliability
If fingerprint verification is required for all transactions, then unauthorized transactions are prevented, but convenience deteriorates when legitimate user cannot verify personally
Solution Approach 1:
The patent introduces a transaction amount parameter that dynamically controls the verification requirement. For small transactions below the threshold, no fingerprint verification is required, providing convenience. For large transactions above the threshold, fingerprint verification is activated to prevent unauthorized transactions. This parameter-based approach balances security and convenience based on the specific transaction context.
