Solution Overview

Problem

Current mobile terminal user mode switching methods are tedious and insecure, as they require manual input of passwords to change modes, leaving private data vulnerable to unauthorized access.

Innovation Solution

Implementing an iris recognition system that collects and matches iris feature data to automatically determine and switch user modes, preventing unauthorized access to private data by using pre-set user iris groups and corresponding permissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual password input is used for user mode switching, then security can be maintained, but operation complexity increases and user convenience deteriorates

Engineering Contradiction:
ImprovesecurityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical manual password input system with an optical biometric recognition system. The iris recognition system uses optical sensors to capture and analyze iris patterns, automatically identifying users and switching modes without requiring manual password entry. This substitution maintains security through unique biometric verification while dramatically improving operation convenience.

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

Solution Approach 2:

The system enables self-service authentication where the user's iris pattern automatically serves as the authentication credential. When a user looks at the camera, the system autonomously captures the iris data, performs pattern matching against stored templates, and switches user modes without requiring the user to manually input passwords or perform additional actions. The system serves itself by using the user's own biological feature for authentication.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual mode switching is required, then security control is maintained, but time consumption increases and productivity decreases

Engineering Contradiction:
Improvesecurity controlVSAvoidmode switching efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary action by pre-registering and storing multiple user iris patterns and their corresponding mode permissions during device setup. This advance preparation enables the system to quickly authenticate and switch modes during actual use without requiring time-consuming manual password entry. The security control rules are also pre-configured, allowing instant enforcement when authentication occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the time-consuming manual password input and mode switching process with automated optical iris recognition. The system captures iris images, extracts features, performs pattern matching, and switches modes automatically, reducing the mode switching process from multiple manual steps to a single glance at the camera, thereby dramatically improving productivity.

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

3Ease of operation

If simple authentication methods are used, then ease of operation improves, but security reliability deteriorates

Engineering Contradiction:
Improveauthentication simplicityVSAvoidsecurity reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces simple but insecure authentication methods (such as basic passwords or patterns) with advanced optical biometric authentication. The iris recognition system captures detailed iris patterns, extracts unique features, and performs cryptographic pattern matching, providing military-grade security while maintaining ease of operation through automated capture and processing.

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

Solution Approach 2:

The system changes the authentication parameter from user-chosen passwords to unique biological iris patterns. Iris patterns contain hundreds of unique features including color, texture, shape, and structural characteristics that are immutable and difficult to replicate. This parameter change dramatically increases security reliability while the automated capture process maintains ease of operation.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention discloses a user mode control method and system based on iris recognition for mobile terminal. When the mobile terminal receives an operation instruction of a user to start a display screen, iris feature data of the current user are scanned. The iris feature data of the current user are matched with iris feature data of users collected in advance, and the corresponding user mode is started when the match succeeds. The present invention prevents a stranger from accessing private data, and greatly improves security of the user data.
