Solution Overview

Problem

Personal computers pose challenges in user authentication due to shared usage among multiple individuals and higher susceptibility to compromise, making existing security measures inconvenient and less effective.

Innovation Solution

A two-factor authentication system that uses a PIN input combined with secure browsing features, device fingerprint verification, and a token generator to authenticate users, allowing access only when a confidence threshold is met, thereby enhancing security without requiring additional user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods are used on personal computers, then security is improved, but user convenience deteriorates due to multiple users sharing the device and additional security steps required

Engineering Contradiction:

Improveauthentication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs authentication automatically by detecting device characteristics and comparing them to stored profiles without requiring user input. The authentication process serves itself by autonomously verifying device identity through hardware/software fingerprints, eliminating the need for manual security questions or token verification while maintaining security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Device characteristics including hardware identifiers and software configurations are captured and stored during an initial setup phase. These pre-captured device fingerprints are then used for subsequent automatic authentication, eliminating the need for repeated manual authentication steps and enabling quick logon for recognized devices.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If device fingerprint verification is implemented, then authentication accuracy is improved, but system complexity increases due to multiple verification steps

Engineering Contradiction:

Improveauthentication accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple device characteristics including hardware identifiers, software configurations, and system parameters are combined into a single composite device fingerprint. This merged fingerprint is stored and compared as one unit, achieving high authentication accuracy through multi-factor verification while presenting a simple single-step authentication interface to users.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Methods and systems for verifying a user's identity on a computing device using two-factor authentication are described. More particularly, the system can use a personal identification number input by a user, together with one or more of a secure browsing feature, a device fingerprint, and a token generator to authenticate the user on the computer.
