Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Debit or credit cards lack the ability to verify the identity of the person carrying them, making them susceptible to fraudulent activity if lost and obtained by unauthorized individuals.
Innovation Solution
A transaction instrument equipped with microprocessors and sensors that sense environmental parameters, performing real-time pattern analysis and augmented authentication by comparing observed hashes to stored hashes, ensuring only authorized users can initiate transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional debit or credit cards are used for transactions, then ease of operation is maintained, but security against fraudulent activity deteriorates because the card cannot sense the identity of the person carrying it
Solution Approach 1:
The patent embeds multiple functional components within the card structure: sensors (accelerometer, gyroscope, magnetometer, ambient light sensor) are integrated into the card body, along with processing units and communication modules. This nesting allows the card to perform environmental sensing and pattern recognition while maintaining a compact form factor suitable for portable use
Solution Approach 2:
The patent introduces an intermediary authentication system between the card and the transaction terminal. The card communicates environmental data and authentication tokens to the terminal, which then verifies the cardholder's identity through pattern recognition algorithms. This intermediary layer enables enhanced security without requiring direct complex interactions between the card and user
2Reliability
If environmental sensors and pattern recognition are added to the card, then transaction security is improved, but device complexity increases
Solution Approach 1:
The patent divides the authentication system into distinct functional segments: environmental sensing components (accelerometer, gyroscope, magnetometer, light sensor), processing units for pattern recognition, communication modules for data exchange, and power management systems. This segmentation allows each component to be optimized independently and facilitates modular integration within the card
Solution Approach 2:
The patent utilizes changes in environmental parameters (acceleration, orientation, magnetic field strength, light intensity) to create unique authentication patterns. By monitoring multiple physical parameters simultaneously and analyzing their temporal variations, the system generates distinctive signatures that verify cardholder identity without requiring complex cryptographic operations
3Measurement precision
If real-time pattern analysis is performed using distributed model, then measurement precision of environmental parameters is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic sampling of environmental parameters rather than continuous monitoring. The sensors take measurements at predetermined time intervals, and the processing unit analyzes these discrete samples to detect patterns. This periodic approach reduces computational load and power consumption compared to continuous real-time analysis, while still maintaining sufficient measurement precision for authentication purposes
