Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If biometrics technology is used for identity authentication, then convenience of identity verification is improved, but reliability of authentication is worsened due to influences from shooting angle, distance, light conditions, and similarities among individuals

Engineering Contradiction:

Improveconvenience of identity verificationVSAvoidreliability of authentication

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent transforms the authentication process from a single-dimension biometric comparison to a multi-dimensional verification system by incorporating location information (GPS coordinates, address data) as an additional authentication dimension. The server compares both biometric data and location data against stored reference information, creating a two-factor authentication mechanism that resolves the reliability issue while maintaining convenience

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a server as an intermediary between the authentication device and the verification system. The server receives authentication requests, performs comprehensive verification including both biometric and location data comparison, and returns authentication results. This intermediary coordinates multiple verification factors to achieve reliable authentication without requiring direct complex interactions between authentication devices

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If personal identity information is stored for authentication purposes, then authentication accuracy is improved, but security and privacy protection are worsened due to unauthorized storage and potential information leakage

Engineering Contradiction:

Improveauthentication accuracyVSAvoidprivacy security risks

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent segments personal identity information into two distinct categories: biometric information (facial features, fingerprints) and location information (GPS coordinates, addresses). Each type of information is stored and processed separately in the server's database, allowing for targeted verification without exposing unnecessary personal data. This segmentation reduces privacy risks by limiting the scope of stored sensitive information

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The server acts as a secure intermediary that stores and processes identity information without exposing it to unauthorized access. The authentication device only sends verification requests and receives results, while the server performs all data comparison operations in a controlled environment. This intermediary architecture protects personal information from leakage while maintaining authentication accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If dynamic rasterization processing is performed on location information, then authentication security is improved, but device complexity and processing time are worsened

Engineering Contradiction:

Improveauthentication securityVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical or algorithmic rasterization processing with a simplified coordinate-based location matching system. Instead of performing dynamic rasterization that divides geographic space into complex grids, the system directly compares GPS coordinates and address data against stored reference location information. This substitution maintains security through location verification while dramatically reducing processing complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention relates to the technical field of identity authentication. Provided are a method and device for authenticating identity information, and a server. The method is executed by a server respectively in communication connection with a target authentication apparatus and a user terminal. The method comprises: receiving first identity information of a user requiring authentication and identifier information of a target authentication apparatus sent by the target authentication apparatus (S102); performing validity authentication of the identity information of the user on the basis of stored first identity information of a valid user and the identifier information of the target authentication apparatus (S104); and sending an authentication result to the target authentication apparatus (S106). The method can effectively protect personal identity information, thereby enhancing security, reliability and convenience of identity authentication, and improving user experience.
