Solution Overview

Problem

Existing remote transaction systems face challenges in ensuring user anonymity while conducting secure transactions, as they often require users to provide personal details to merchants, exposing them to fraud risks and inefficiencies, and the use of access credentials can lead to unauthorized transactions.

Innovation Solution

A secure remote transaction framework that embeds a checkout element within a website, allowing communication with an initiator server to populate transaction details without exposing sensitive information to the merchant, using tokens generated by a secure remote transaction platform to complete transactions securely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users provide personal details to merchants to complete transactions, then transaction security and authentication are improved, but user anonymity and exposure to fraud risks deteriorate

Engineering Contradiction:
Improvetransaction authenticationVSAvoidfraud risk and information exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a token as an intermediary that mediates between the user and merchant. The token contains authentication information but does not reveal the user's personal details to the merchant, thus maintaining transaction security while preserving user anonymity and reducing fraud risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the essential authentication functionality from personal details. Instead of requiring users to provide sensitive personal information, the system extracts only the necessary authentication capability and encapsulates it in a token, separating the authentication function from personal data exposure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If merchants obtain access credentials from users during transactions, then transaction authorization is improved, but security risks and unauthorized transaction potential deteriorate

Engineering Contradiction:
Improvetransaction authorizationVSAvoidunauthorized transaction risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements single-use tokens that are valid for only one transaction. After use, the token becomes invalid, preventing merchants from reusing or misusing the authentication credentials. This disposable approach maintains ease of authorization while eliminating the risk of unauthorized future transactions.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The token serves as an intermediary credential that provides authorization without exposing long-term access credentials. The merchant receives the token for authorization purposes but cannot use it for any other purpose, thus maintaining operational ease while preventing unauthorized transactions.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If users remain anonymous during transactions, then privacy protection is improved, but transaction verification and trust establishment deteriorate

Engineering Contradiction:
Improveprivacy exposureVSAvoidtransaction verification
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The token acts as a mediator that carries verification information without revealing user identity. The merchant can verify the token's authenticity and validity to ensure transaction reliability, while the user's personal information remains protected and anonymous throughout the process.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of the invention are directed to systems and methods of providing secure remote transaction (SRT) transactions. In some embodiments, a resource provider is able to embed a checkout element into a webpage that it hosts. The checkout element enables interaction between a user that has accessed the webpage and an initiator application server located remotely in order to complete a transaction while preventing the resource provider from gaining access to sensitive information. In some embodiments, the user's information may be determined by an initiator server and populated into the checkout element.
