Solution Overview

Problem

Existing methods for user authentication in networks, particularly in public facilities, lack security and efficiency, especially when using biometric signatures.

Innovation Solution

A system and method for authenticating users using biometric signatures, involving a sign-on server that receives a biometric sample from a user device, compares it with stored data, and grants network access if the sample matches a valid biometric signature associated with a username.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional authentication methods (information entry, agreement acceptance) are used in public facilities, then ease of operation is improved, but security deteriorates

Engineering Contradiction:
Improveease of authenticationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (keyboard entry, mouse clicking) with biometric authentication using fingerprint sensors, facial recognition, or other physiological characteristics. This substitution maintains ease of operation by using automatic sensing while dramatically improving security through unique biological identifiers that cannot be easily replicated or shared.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If biometric authentication is implemented, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal biometric authentication system that can be deployed across multiple devices and platforms (mobile phones, computers, tablets, access control systems). By creating a centralized database and using standardized biometric algorithms, the system achieves high security without requiring each individual device to be complex, as the authentication logic is distributed and standardized.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a centralized biometric database and authentication server as intermediaries between the user devices and the authentication process. These intermediaries handle the complex tasks of storing biometric templates, comparing authentication data, and making authorization decisions, thereby keeping individual endpoint devices simple while maintaining high security through centralized control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If biometric samples are stored and processed, then authentication accuracy is improved, but data protection requirements increase

Engineering Contradiction:
Improveauthentication accuracyVSAvoiddata protection risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential biometric features (creating biometric templates or hashes) and stores these processed representations rather than raw biometric data. This extraction process removes personally identifiable information while retaining the unique characteristics needed for authentication, thereby improving authentication accuracy while reducing data protection risks by storing minimal necessary data.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a secure, isolated environment for storing and processing biometric data through encrypted databases, secure authentication servers, and controlled access protocols. This 'inert environment' protects biometric information from unauthorized access, hacking, and misuse while allowing accurate authentication to occur within the protected system boundaries.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

AI summary

Methods, systems, and media for authenticating users using biometric signatures are provided. In some embodiments, the method comprises: receiving, from a user device, an indication that the user device is to be connected to a communication network; in response to receiving the indication, causing a user interface to be presented on the user device that receives a username corresponding to a user of the user device; receiving, from the user device, a biometric sample corresponding to the user of the user device; determining whether the biometric sample matches a stored biometric sample associated with the username; and in response to determining that the biometric sample matches the stored biometric sample associated with the user name, causing the user device to be connected to the communication network.
