Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing user authentication systems are vulnerable to hacking and unauthorized access, as they often rely on easily guessable or shared passwords, and may require users to carry separate devices for token generation, which can be lost or tampered with.

Innovation Solution

A biometric-based authentication system that uses software running on personal devices with biometric sensors, in conjunction with a server, to authenticate users by comparing biometric data such as iris, face, fingerprint, or speech data with stored profiles, and optionally sends a one-time passcode for additional verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional password-based authentication is used, then users can access digital systems and physical locations, but the system becomes vulnerable to hacking and unauthorized access

Engineering Contradiction:

Improveauthentication securityVSAvoidhacking and unauthorized access

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical/password-based authentication systems with biometric authentication. Instead of using passwords that can be guessed or hacked, the system uses biological characteristics (iris patterns, fingerprints, facial recognition) that are unique to each individual and extremely difficult to replicate or steal, thereby fundamentally improving authentication security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the authentication parameter from something users know (passwords) to something users are (biometric characteristics). This parameter change makes authentication more reliable because biometric data cannot be forgotten, lost, or easily compromised like passwords, directly addressing the security vulnerability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If token generators and one-time passwords are used, then authentication security is improved, but the system becomes overly complex and costly

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the authentication verification process from external devices (token generators, separate authentication devices) and integrates it directly into the user's personal device. The biometric authentication is performed locally on the user's smartphone or computer, eliminating the need for separate token-generating devices and simplifying the overall system architecture.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent makes the personal device serve multiple functions: it stores biometric data, performs authentication verification, and provides secure access to both digital and physical locations. This multi-functionality eliminates the need for separate authentication devices, reducing system complexity while maintaining high security standards.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If key cards with digital identifiers are used for physical location access, then access control is improved, but users must carry the card and it can be misused by unauthorized individuals

Engineering Contradiction:

Improveaccess controlVSAvoidunauthorized use of key card

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces physical key cards with biometric authentication. Instead of relying on a physical card that can be lost, stolen, or copied, the system uses unique biological characteristics that are inherently tied to the authorized user's body, making unauthorized use impossible and eliminating the need to carry physical access credentials.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If multiple usernames and passwords are required for different accounts, then access to multiple digital systems is enabled, but users forget credentials and security is compromised

Engineering Contradiction:

Improveaccess to multiple accountsVSAvoidauthentication reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a universal biometric authentication system that can access multiple digital accounts and physical locations using a single biometric identifier. Instead of requiring separate passwords for each account, the user's fingerprint, iris pattern, or facial recognition data serves as a universal key, enabling access to multiple systems while improving reliability since the biometric data cannot be forgotten or lost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems and methods are provided involving a user registration and authentication system for granting access to digital systems, content, computing systems and devices, applications including document execution applications, and physical locations. The registration and authentication system may involve a personal device, a computing device and/or a server and may grant access to digital systems, applications, and content. The registration and authentication system may also involve a personal device, an interface device, a secure system and/or a server and grant access to computing systems, applications, devices and physical locations. A user may be registered for the authentication system in-person by a third-party to perform in-person verification.
