Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The frequent need to enter payment card information at multiple merchant websites and manage multiple accounts, along with the risk of information theft, diminishes the online shopping experience and security.

Innovation Solution

Utilizing unsupervised learning classifiers to determine merchant and user groups based on payment card types, spending habits, and demographic data to recommend merchant registrations, and employing virtual payment card information that does not include the actual card number for secure transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If payment card information is entered at each merchant website, then transactions can be completed, but the online experience is diminished and security risks increase

Engineering Contradiction:

ImprovesecurityVSAvoidonline experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a payment card registration system that acts as an intermediary between users and multiple merchant websites. The system automatically registers payment card information with selected merchants based on unsupervised learning classifications, eliminating the need for users to manually enter card details at each site while maintaining security through controlled registration processes.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary registration of payment card information with merchant accounts before actual transactions occur. By using machine learning to predict which merchants a user will visit, the system proactively completes registration in advance, so users can shop without repeatedly entering card information.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple merchant accounts are managed manually, then payment flexibility is maintained, but account management becomes difficult

Engineering Contradiction:

Improvepayment flexibilityVSAvoidaccount management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables self-service account management by automatically maintaining payment card registrations across multiple merchant accounts. The unsupervised learning classifier continuously analyzes user behavior patterns and automatically updates registrations with new merchants, eliminating the need for manual account management while preserving payment flexibility.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The payment card registration system serves multiple functions simultaneously: it manages payments across diverse merchants, learns user preferences through machine learning, automatically registers cards with relevant merchants, and provides a unified interface for account management. This multi-functionality reduces complexity while maintaining adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If payment card information is stored at multiple merchant websites, then convenience is improved, but the risk of information theft increases

Engineering Contradiction:

ImproveconvenienceVSAvoidinformation theft risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system introduces a secure intermediary layer between the user's payment card information and merchant websites. Rather than directly exposing card details to multiple merchants, the system controls and manages the registration process through unsupervised learning classifications, reducing the attack surface for potential theft while maintaining convenience for users.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Measurement precision

If manual account updates are performed for each merchant, then payment card changes are accurate, but time consumption increases

Engineering Contradiction:

Improvepayment card update accuracyVSAvoidtime for account updates

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary updates to merchant accounts when payment card information changes are detected. Instead of requiring users to manually update each merchant account after a card change, the system proactively identifies affected merchants based on learned patterns and automatically updates their records, ensuring accuracy while saving significant time.

Inventive Principle:

Principle #10Preliminary action

AI summary

Aspects described herein may relate to methods, systems, and apparatuses for applying machine learning techniques as part of registering, for a user, a payment card with at least one account of a merchant. The machine learning technique may be an unsupervised learning classifier that is configured to determine classifications of merchant groups and/or user groups. Based on a classification, the user may be able to select which merchants to register the payment card. Based on the selection, the payment card may be registered with the user's account at the selected merchants. Further, the registration may be performed based on virtual payment card information configured for use with the merchant. The virtual payment card information may be configured to initiate transactions only with the merchant.
