Solution Overview

Problem

Password-based login systems are inconvenient for users, prone to security risks, and two-factor authentication methods using hardware devices are burdensome and unreliable.

Innovation Solution

A graphical identifier authentication system that generates and captures one-time use graphical authentication identifiers, allowing users to automatically authenticate without manually entering credentials, using a mobile device to interpret and respond to authentication requests from websites or other entities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If password-based login is used, then users can access multiple websites, but security risks increase and user convenience deteriorates

Engineering Contradiction:

Improveaccess to multiple websitesVSAvoidsecurity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a graphical authentication identifier as an intermediary element between the user and the password entry field. This graphical identifier is displayed on the login screen and contains encoded authentication information that automatically provides credentials to the website, eliminating the need for users to manually enter passwords while maintaining security through encoded transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical action of manual password typing with an automated graphical identifier system. The graphical authentication identifier is captured by a mobile device camera and automatically processed to provide authentication credentials, substituting the manual mechanical process with an automated optical recognition and data transmission system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If two-factor authentication with hardware devices is used, then security improves, but device complexity and user burden increase

Engineering Contradiction:

ImprovesecurityVSAvoidhardware devices

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the mobile communication device universal by enabling it to perform multiple functions: capturing the graphical authentication identifier via camera, processing the encoded authentication information, generating rolling values for two-factor authentication, and transmitting credentials automatically. This eliminates the need for separate dedicated hardware authentication devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses a visual copy of authentication information (the graphical identifier displayed on the login screen) that contains encoded credentials. This graphical copy is captured by the mobile device and processed to provide authentication, replacing the need for physical hardware tokens with a visual information carrier that can be easily captured and processed.

Inventive Principle:

Principle #26Copying

3Reliability

If manual password entry is required, then authentication can be performed, but user convenience and time efficiency deteriorate

Engineering Contradiction:

ImproveauthenticationVSAvoidmanual entry time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-encoding authentication information within the graphical identifier before the user needs to login. The graphical authentication identifier is generated in advance with embedded credentials, so when the user captures it with their mobile device, the authentication information is already prepared and can be automatically transmitted without requiring manual entry or additional user actions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs self-service by automatically capturing, processing, and transmitting authentication credentials without requiring manual user intervention. The graphical authentication identifier system encodes its own authentication information and enables automatic credential provision through mobile device capture, eliminating the need for users to manually enter passwords or provide authentication codes.

Inventive Principle:

Principle #25Self-service

AI summary

A graphical authentication identifier is used to facilitate automatic authentication of a user. A graphical identifier authentication system receives a request from an authenticating entity for a onetime use graphical authentication identifier. In response to the received request, a onetime use graphical authentication identifier to be displayed by the authenticating entity is generated. A request for user authentication information by the authenticating entity is encoded in the graphical authentication identifier, which is transmitted to the authenticating entity for display (e.g., on a login screen). The onetime use graphical authentication identifier being displayed by the authenticating entity is captured by a registered user operated computing device. In response, the requested user authentication information is transmitted to the authenticating entity, such that the user is automatically authenticated to the authenticating entity, without the user manually entering the requested user authentication information.
