Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The lack of secure identity verification in online financial and insurance applications poses risks, especially for substantial monetary obligations, as existing methods lack robustness in confirming the identity of customers.

Innovation Solution

A vendor system that utilizes biometric information, such as fingerprint or voice scans, to create and verify electronic signatures, ensuring that only authorized users can electronically sign documents, transfer funds, or notarize documents, by comparing received biometric data with registered information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric verification is implemented, then security and reliability are improved, but device complexity increases

Engineering Contradiction:

Improveidentity verification securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces biometric data as an intermediary element between the user and the electronic signature process. The biometric verification system acts as a mediator that confirms user identity before allowing signature execution, thereby enhancing security without requiring fundamental changes to the core e-signature infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical identity verification methods (physical signatures, paper-based authentication) with biometric scanning and digital verification systems. This substitution uses optical, acoustic, or electronic fields to capture and verify biometric characteristics, improving reliability while the digital nature keeps complexity manageable

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If traditional username and password verification is used, then ease of operation is maintained, but security and reliability deteriorate

Engineering Contradiction:

Improveuser convenienceVSAvoididentity verification security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent performs biometric verification as a preliminary action before the actual electronic signature is executed. The system captures and verifies biometric data in advance of the signing action, ensuring identity confirmation is completed before the critical moment of document execution, thereby maintaining convenience while enhancing security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the verification parameter from simple credential checking (username/password) to biometric characteristic analysis. By shifting from verifying knowledge-based secrets to verifying physiological or behavioral traits, the system improves reliability while keeping the user experience relatively simple through automated scanning and comparison

Inventive Principle:

Principle #35Parameter changes

AI summary

A vendor system may allow a user to electronically sign documents. The vendor system may receive a package of biometric information from the user. In one embodiment, the vendor system may compare the received package of biometric information with a registered package of biometric information associated with the user. If the received package of biometric information matches the registered package of biometric information, the vendor system may sign a document with an electronic signature.
