Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing email-based e-commerce systems lack robust security measures, necessitating password authentication that can be cumbersome and vulnerable to unauthorized access, limiting their viability for secure financial transactions.

Innovation Solution

Implementing a system with dual authorization or multi-factor authentication using email-based confirmations, separate media alerts, and a management oversight tool to enhance security, allowing transactions without requiring a password prompt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If email-based financial transaction systems are implemented, then new possibilities for consumer transactions are enabled, but security vulnerabilities and unauthorized transactions occur

Engineering Contradiction:

Improvetransaction capabilityVSAvoidsecurity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary authentication system that mediates between the email-based transaction system and the financial transaction completion. This intermediary layer verifies sender identity through multiple channels (email, SMS, voice call) before allowing transactions to proceed, thus enabling email-based transactions while maintaining security through the mediating authentication mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary authentication actions before the actual financial transaction occurs. The sender must first verify their identity through email confirmation and additional verification channels (SMS codes, voice calls) before the transaction is authorized. This preliminary security check prevents unauthorized transactions while maintaining the email-based transaction capability.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If traditional password-based authentication is used, then user verification is achieved, but password management burden and security risks increase

Engineering Contradiction:

Improveauthentication simplicityVSAvoidpassword management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the password requirement from the authentication process entirely. Instead of requiring users to remember and manage passwords, the system uses email address as the identifier and implements passwordless authentication through email confirmation links and alternative verification channels (SMS, voice calls), thereby eliminating password management complexity while maintaining ease of operation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables self-service authentication where the user's email client itself serves as the authentication mechanism. The email client automatically handles verification through confirmation links sent to the user's email address, eliminating the need for manual password entry and management while maintaining simple user interaction.

Inventive Principle:

Principle #25Self-service

3Reliability

If email client security is leveraged, then secure correspondence is provided, but transaction verification limitations occur

Engineering Contradiction:

Improveemail securityVSAvoidverification capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the authentication system universal by supporting multiple verification channels beyond just email client security. The system can verify identities through email confirmation, SMS text messages with verification codes, and voice calls with automated code delivery. This multi-functional verification capability maintains the security benefits of email while adding versatility through alternative verification methods.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system transitions from a single-dimension email-based verification to multi-dimensional verification by adding spatial and temporal dimensions. Verification can occur through different channels (email, SMS, voice), at different times (immediate email confirmation, delayed SMS codes), and through different mechanisms (confirmation links, verification codes), thereby expanding verification capability while maintaining email security foundations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An email-based e-commerce system is disclosed with additional features for added security. The system may include security features for email based e-commerce providing added assurance to customers of a higher level of protection than generally required. These security features enhance the password reset function without requiring a password, generate confirmations on outside messaging systems and implement an oversight management tool for authorizing transactions. The methods and apparatus described herein may enhance security by designing a system that can confirm payments through a separate non-email based media. The e-commerce system may send alerts or requests for confirmation in a variety of media to ensure a secure payment process. The methods and apparatus described herein may expand the list of individuals that may request or approve payments based on a single account registered by a single credit card holder. A single user may receive requests from registered sub-customers for payments by email.
