Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contactless card transactions face challenges in data security and authentication, with existing security measures being easily circumvented by bad actors, leading to increased fraud risks in digital transactions.
Innovation Solution
A system that associates biometric data with a contactless card, authenticating the card by decrypting encrypted data, receiving and comparing biometric data with a stored profile, and authorizing transactions only when the data matches, with additional security measures for high-risk transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures (user names and passwords) are used for digital transactions, then ease of operation is maintained, but reliability deteriorates due to frequent circumvention by bad actors
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (usernames and passwords) with biometric authentication systems. The mobile device captures biometric data (fingerprint, facial recognition, or voice recognition) and compares it against stored biometric profiles to authenticate users. This substitution eliminates the weaknesses of traditional password-based systems while maintaining user convenience, as biometric authentication requires no manual input and is difficult to circumvent.
Solution Approach 2:
The patent changes the fundamental parameter of authentication from knowledge-based (something you know: passwords) to biology-based (something you are: biometric traits). By storing and comparing biometric data profiles, the system transforms the authentication mechanism into a more reliable form that cannot be easily compromised. The system also dynamically adjusts security levels based on transaction risk factors, changing authentication parameters adaptively.
2Reliability
If biometric verification is implemented for all transactions, then reliability improves through enhanced security, but device complexity increases due to additional authentication components
Solution Approach 1:
The patent makes the mobile device universal by integrating multiple functions into a single platform: contactless card reader, biometric sensor, authentication server, and transaction processor. The mobile device replaces multiple separate security devices (card reader, fingerprint scanner, password manager) with a single multi-functional device. This universality reduces overall system complexity despite adding biometric capabilities, as the mobile device already contains the necessary hardware and software components.
Solution Approach 2:
The patent merges the authentication function with the existing mobile device ecosystem. Rather than adding separate authentication hardware, the system combines biometric sensing, data storage, processing, and verification within the mobile device itself. The mobile device serves as both the card reader and the biometric authentication system, merging multiple security functions into a unified platform that leverages existing mobile infrastructure.
3Reliability
If encrypted data from contactless cards is decrypted for authentication, then reliability improves through verification, but loss of information increases due to potential data breaches
Solution Approach 1:
The patent performs preliminary encryption of card data before it leaves the contactless card. The mobile device receives already-encrypted data and only decrypts it locally for immediate authentication purposes. Biometric profiles are pre-stored and encrypted in the mobile device. This preliminary security measure ensures that sensitive data is protected during transmission and storage, reducing the risk of information loss while enabling reliable authentication when needed.
Solution Approach 2:
The patent applies different security measures to different data elements. Card authentication data is encrypted and verified locally on the mobile device without being transmitted to external servers. Biometric profiles are stored locally in encrypted form. Only authentication results (approve/deny) are transmitted to merchants. This localized handling of sensitive information minimizes exposure risks while maintaining authentication reliability.
4Reliability
If multiple security layers (contactless card + biometric) are implemented, then reliability improves through enhanced verification, but ease of operation deteriorates due to additional authentication steps
Solution Approach 1:
The patent implements dynamic authentication that adapts to transaction circumstances. The system evaluates transaction risk factors (amount, merchant type, location, device history) and dynamically adjusts the authentication required. For low-risk transactions, the system may use simplified authentication. For high-risk transactions, full biometric verification is required. This dynamic approach maintains reliability for risky transactions while improving ease of operation for routine transactions.
Solution Approach 2:
The patent performs biometric profile setup and encryption in advance during device initialization. When a transaction occurs, the pre-configured system can quickly capture and compare biometric data without requiring complex real-time processing. The mobile device already has the necessary algorithms and stored profiles ready, enabling rapid authentication that feels instantaneous to the user despite the multiple security layers.

AI summary
Systems and methods for validating and securing transactions are provided. A registration process can include receiving, via a short-range communication antenna of a mobile device, encrypted data from a contactless card, successfully decrypting the encrypted data to authenticate the contactless card, receiving, via the mobile device, first biometric data, and storing the first biometric data in a biometric profile of a customer account associated with the contactless card. An authorization process can include transmitting a solicitation message to the mobile device responsive to receiving a request to authorize a digital transaction in connection with the customer account, receiving, via the mobile device, second biometric data responsive to the solicitation message, comparing the second biometric data with the biometric profile, authorizing the digital transaction when the second biometric data matches the biometric profile, and denying the digital transaction when the second biometric data fails to match the biometric profile.
