Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional passwords and PINs are used for authentication, then ease of operation is improved, but security against interception and observation attacks deteriorates
Solution Approach 1:
The patent replaces traditional mechanical input methods (keyboard typing, PIN entry) with a wireless communication-based authentication system. The mobile device communicates with the contactless card through NFC or similar wireless technology, eliminating the need for visible manual input and thereby preventing shoulder-surfing and eavesdropping attacks while maintaining ease of use.
Solution Approach 2:
The patent introduces an intermediary wireless communication channel between the user's contactless card and the mobile device. This intermediary mechanism allows authentication data to be transmitted securely without direct human observation or interception, solving the vulnerability of traditional visible input methods while preserving operational convenience.
2Reliability
If contactless card with pattern recognition is implemented, then security against interception is improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of contactless cards, which are already widely possessed by users for financial and identification purposes. By making these existing cards functional for authentication through pattern recognition, the system avoids requiring specialized hardware while enhancing security. The mobile device's existing NFC capability is multi-used for both communication and authentication functions.
Solution Approach 2:
The authentication system utilizes the mobile device's own resources (NFC antenna, processor, pattern recognition algorithms) to verify the contactless card patterns. The device serves itself by performing the verification locally without requiring additional external verification hardware, thereby enhancing security while minimizing the increase in overall system complexity.
3Measurement precision
If multiple antennas are used for detection, then measurement precision of communication pattern is improved, but device complexity increases
Solution Approach 1:
The patent divides the detection function across multiple antennas positioned at different locations on the mobile device. Each antenna independently detects communication signals from the contactless card, and the processor combines these segmented detections to create a comprehensive pattern recognition system. This segmentation improves measurement precision by providing multiple data points while distributing the complexity across separate components.
