Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional user authentication methods during calls are burdensome, inefficient, and costly, often requiring personal information such as social security numbers, leading to user hesitation and increased call duration.

Innovation Solution

Implementing a quick access service that allows users to authenticate using a unique identifier and user verifier, such as a phone number and PIN, associated with their user profile, enabling efficient and secure authentication without the need for personal identifiable information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods are used requiring personal information, then authentication security is maintained, but authentication time increases and user experience deteriorates

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing a mapping between device identifiers and user profiles during device registration. This advance preparation allows the authentication system to quickly match devices to users without requiring real-time personal information verification, thus reducing authentication time while maintaining security through pre-validated device-user associations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces device identifiers as intermediary elements that mediate between the user and the authentication system. Instead of directly verifying personal information, the system uses device identifiers as a proxy to access user profiles and verify authentication credentials, thereby streamlining the authentication process and reducing time loss while maintaining security

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If traditional authentication methods requiring personal information are used, then authentication can be performed, but operational costs increase and user hesitation increases

Engineering Contradiction:

Improveauthentication efficiencyVSAvoidoperational cost

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent extracts sensitive personal information from the authentication process by using device identifiers as substitutes. The system extracts only the necessary authentication credentials from the user profile associated with the device, eliminating the need to transmit and process sensitive personal information during authentication, thereby reducing operational costs and improving efficiency

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates a copy of the user profile associated with the device identifier rather than requiring direct access to personal information. This profile copy contains only the necessary authentication credentials, allowing the system to verify user identity without handling sensitive data, thus reducing operational complexity and costs

Inventive Principle:

Principle #26Copying

3Reliability

If traditional authentication methods are used, then user identity can be verified, but transmission of sensitive information increases security risks

Engineering Contradiction:

Improveuser identity verificationVSAvoidsecurity risk from sensitive information transmission

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Device identifiers serve as intermediary elements that prevent direct transmission of sensitive personal information during authentication. The system uses these identifiers to access and verify user profiles securely, maintaining user identity verification while eliminating the need to transmit sensitive data over communication channels, thereby reducing security risks

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts sensitive information from the authentication transmission process by using device identifiers as substitutes. Only non-sensitive authentication credentials associated with the device identifier are transmitted and verified, eliminating the transmission of sensitive personal information while maintaining reliable user identity verification

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Methods and systems described in this disclosure allow customers to quickly be authenticated. In some embodiments, a device and a user verifier are associated with a user profile. When a call is received from the device, the user may be requested to input the user verifier. After verifying that the device is unique to the user and that the user verifier matches the user verifier associated with the user profile, the user may be authenticated to the call or activity.
