Solution Overview

Problem

Conventional authentication methods for electronic devices require multiple user interactions, making the process complicated and cumbersome, especially when dealing with encrypted applications and files.

Innovation Solution

An authentication method that collects a user's biological feature, such as a fingerprint or facial image, upon touching an icon, compares it with the bound biological feature, and logs in to the application or file library without displaying an unlock screen, allowing for single interaction authentication and simplified user operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional authentication method is used (display unlock screen and verify password/pattern), then security verification is achieved, but user operations become complicated and require multiple interactions

Engineering Contradiction:
Improveauthentication operation simplicityVSAvoidauthentication process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the authentication interface with the application icon interaction. Instead of separating the unlock screen as a distinct authentication interface, the system combines the icon clicking action with biological feature collection, allowing authentication to occur within the same interaction flow as application launching.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the unlock screen display step from the authentication process. By removing the intermediate unlock screen that requires separate interaction, the system directly collects biological features when the user clicks the application icon, thereby simplifying the user操作流程 while maintaining security verification.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If multiple interaction steps are used for authentication (click icon, enter password on unlock screen), then verification security is maintained, but user time and operational steps increase

Engineering Contradiction:
Improveauthentication speedVSAvoidauthentication time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by having the user bind their biological feature to the application in advance. During authentication, the system directly collects and verifies the pre-bound biological feature without requiring the user to manually input credentials, thereby reducing authentication time and steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent skips the intermediate steps of displaying an unlock screen and manually entering passwords or patterns. By rushing through the authentication process to directly collect and verify biological features during icon interaction, the system significantly reduces the time and steps required for authentication.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

This application discloses an authentication method and an electronic device. When a user performs a touch operation on an icon of a first application, a biological feature of the user is directly collected without displaying an authentication screen, the collected biological feature is compared with a biological feature bound to the first application, and when a comparison result indicates that the collected biological feature matches the biological feature bound to the first application, the first application is logged in to. Based on the foregoing process, authentication can be implemented through only one interaction between the user and the electronic device, so that user operations are simplified.
