Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional hands-free interaction systems between users and resource providers face challenges such as signal interference, security concerns due to lack of authentication, and unauthorized access, as they rely on wireless signals and do not ensure proper authorization for resource access.

Innovation Solution

A method and system where a mobile communication device receives a broadcast signal from a beacon device, authenticates both the entity and itself through an authentication system, and only initiates an interaction process once both are confirmed authentic, using cryptographic techniques and a blockchain for secure verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless signals are used for hands-free interaction, then interaction speed is improved, but security and authentication reliability deteriorate

Engineering Contradiction:

Improveinteraction speedVSAvoidauthentication reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

A beacon device is introduced as an intermediary between the mobile communication device and the resource provider. The beacon device broadcasts identification information and credentials, enabling the mobile device to authenticate with the resource provider without direct wireless signal transmission of sensitive credentials, thus improving security while maintaining hands-free interaction speed

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional mechanical card insertion and physical interaction with a wireless-based authentication system using mobile communication devices and beacon devices, eliminating the need for physical manipulation of access tokens while maintaining or improving security through cryptographic credentials

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional hands-free interaction systems are used, then ease of operation is improved, but security against fraudulent activities deteriorates

Engineering Contradiction:

Improvehands-free convenienceVSAvoidsecurity risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The authentication system acts as a secure intermediary that verifies credentials before allowing interaction. The beacon device broadcasts identification information and credentials, and the mobile device must authenticate with the resource provider through this controlled intermediary system, preventing direct unauthorized access while maintaining convenience

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary authentication actions before allowing the main interaction to proceed. Credentials are verified in advance through the authentication system, and only after successful verification does the system permit the resource provider interaction to occur, preventing fraudulent activities before they can harm the system

Inventive Principle:

Principle #10Preliminary action

3Productivity

If wireless broadcast signals are used for interaction, then interaction speed is improved, but reliability of signal identification deteriorates

Engineering Contradiction:

Improveinteraction speedVSAvoidsignal identification accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The beacon device serves as a dedicated intermediary that broadcasts identification information and credentials at the resource provider location. The mobile communication device receives this specific broadcast signal and uses it to authenticate with the resource provider, ensuring accurate signal identification while maintaining fast hands-free interaction

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The beacon device is deployed locally at the resource provider location and broadcasts identification information specific to that location. This localizes the authentication process to the specific resource provider, ensuring that the mobile device correctly identifies and interacts with the intended resource provider without confusion from other signals

Inventive Principle:

Principle #3Local quality

AI summary

The method includes receiving a broadcast signal from a beacon device, the broadcast signal encoding a first credential associated with a first entity. In response to receipt of the broadcast signal, the mobile communication device transmits the received first credential to an authentication system. The authentication system determines if the first entity associated with the broadcast signal is authentic and generates a confirmation message confirming the authenticity of the first entity. The mobile communication device then receives the confirmation message indicating that the first entity is authentic. The mobile communication thereafter receives and transmits a second credential for the mobile communication device to the beacon device, which transmits the second credential to the authentication system. The authentication system then confirms the authenticity of the mobile communication device. Then, the beacon device can initiate an interaction process with the user of the mobile communication device.
