Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods using passwords on mobile devices are time-consuming, error-prone, and insecure, particularly when accessing financial accounts or web pages.
Innovation Solution
A method utilizing a Near-Field Communication (NFC) enabled credit card to acquire a unique digital identifier, which is used to authenticate the cardholder and access financial accounts on a mobile device, eliminating the need for manual password entry by launching a secure application connection to a financial institution's server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password entry is used for authentication, then security is maintained, but authentication time increases to 8-10 seconds and errors occur
Solution Approach 1:
The patent applies preliminary action by pre-storing biometric data (fingerprint, facial recognition data) and authentication credentials in secure elements of the mobile device and NFC card. When authentication is needed, the system quickly retrieves and compares these pre-stored data without requiring real-time manual input, thus reducing authentication time while maintaining security.
Solution Approach 2:
The patent replaces the mechanical keyboard typing process with biometric sensing systems (fingerprint sensors, facial recognition cameras) and NFC wireless communication. This substitution eliminates the manual character-by-character input process, reducing authentication time from 8-10 seconds to approximately 2-3 seconds while maintaining or improving security through harder-to-replicate biometric data.
2Reliability
If password entry is used for authentication, then security is maintained, but error rate increases due to typing mistakes
Solution Approach 1:
The patent replaces the manual typing process with automated biometric sensing and NFC communication. Fingerprint sensors capture ridge patterns, facial recognition cameras map facial features, and NFC readers exchange encrypted credentials wirelessly. These automated processes eliminate human typing errors while maintaining security through cryptographic verification of biometric data against stored templates.
Solution Approach 2:
The patent creates digital copies of unique physical characteristics (fingerprint patterns, facial geometry) and stores them in secure elements. During authentication, the system captures a new copy and compares it against the stored template using cryptographic algorithms. This copying and comparison process eliminates errors associated with manual password entry while maintaining high security through the uniqueness of biometric traits.
3Productivity
If NFC card and mobile device are used for authentication, then authentication speed increases to 2-3 seconds, but system complexity increases
Solution Approach 1:
The patent implements multi-functionality by integrating multiple authentication methods (NFC card reading, fingerprint sensing, facial recognition) into a single unified system. The mobile device serves as both the authentication credential holder and the verification system, while the NFC card contains encrypted authentication data that works across multiple devices. This universal approach consolidates complexity into standardized components that can be reused across different authentication scenarios.
Solution Approach 2:
The patent introduces secure elements and trusted execution environments as intermediaries between the biometric sensors/NFC readers and the authentication logic. These secure intermediaries handle the cryptographic operations and data protection, isolating the complex security protocols from the user interface and application logic. This mediation allows fast authentication while managing system complexity through layered security architecture.
