Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current transaction methods, especially in e-commerce and brick-and-mortar commerce, face security concerns due to the need to transmit personal information, lack of authentication for parties involved, and vulnerabilities in existing payment systems, which can lead to identity theft and insecure transactions.

Innovation Solution

A system utilizing a multiplex code, which is a secure, optically scannable tag with higher density capabilities and nonlinear patterns, allows for secure authentication and transactions by using a mobile device's camera to scan and decrypt the code, eliminating the need for password entry and credit card information, and ensuring secure information transfer through encryption and hashing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional payment methods (credit/debit cards, PayPal) are used, then transactions can be conducted, but security concerns arise due to transmission of personal information and lack of authentication

Engineering Contradiction:

Improvetransaction securityVSAvoidpersonal information transmission

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces an optical code as an intermediary carrier that replaces direct transmission of personal information. The code contains encrypted transaction data that can be scanned and processed without exposing sensitive information like credit card numbers or passwords, thus resolving the contradiction between enabling transactions and protecting personal information

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/electronic payment systems (card readers, password verification) with an optical scanning system. By using camera-based optical codes, the system eliminates the need for physical card insertion and password entry, reducing security vulnerabilities associated with information transmission while maintaining transaction functionality

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If QR codes are used for transactions, then ease of use is improved, but security is compromised due to lack of authentication capabilities

Engineering Contradiction:

Improvetransaction convenienceVSAvoidauthentication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent creates a composite optical code structure that combines multiple functional elements: identification markers, encrypted data fields, and authentication codes. This composite design maintains the simplicity of QR-like scanning while adding layered security features including cryptographic authentication that verifies both parties involved in the transaction

Inventive Principle:

Principle #40Composite materials

3Quantity of substance

If multiplex codes with higher density capabilities are used, then information storage capacity is improved, but device complexity increases

Engineering Contradiction:

Improveinformation densityVSAvoidcode structure complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the optical code into segmented regions with distinct functions: identification zones, data encoding areas, and authentication sections. This segmentation allows the complex multiplex code to be processed systematically by breaking it down into manageable components, reducing the effective complexity for both encoding and decoding operations while maintaining high information density

Inventive Principle:

Principle #1Segmentation

AI summary

A method for limiting exposure to infectious disease by controlling access to a controlled access venue to admit individuals who have tested non-infectious for a particular highly infectious disease or have received a vaccination against the same comprises receiving, at a central website operator server, consumer user identification information from consumer users and storing that information in a consumer user database associated with the server. A biometric identifier from the consumer users is transmitted to the consumer user database and each associated with its respective associated consumer user to form an enrollment record. Identity of a presented individual is collected at a medical certification point and an authority record is created in an accessible authority database. At said medical certification point, an antibody test or vaccination is administered and the same is noted in the authority record. A biometric is collected from a venue presented consumer at a presentation venue, compared to authority records for a match, and the result provided to the venue.
