Solution Overview

Problem

Existing mobile terminal login methods are insecure and cumbersome, as they require manual input of usernames and passwords, making it easy for unauthorized access to personal information.

Innovation Solution

A method that uses fingerprint authentication to quickly and securely log into multiple application programs by matching input fingerprint information with locally preset correct information, allowing for automatic retrieval and use of corresponding usernames and passwords.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual username and password input is used for login, then login security can be maintained, but login process becomes tedious and time-consuming

Engineering Contradiction:
Improvelogin securityVSAvoidlogin time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically retrieving and pre-filling username and password information from locally stored login data before the user completes the login process. This eliminates the need for manual input of credentials while maintaining security through fingerprint verification, thus resolving the contradiction between security and login time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces fingerprint recognition as an intermediary authentication mechanism between the user and the login system. Instead of directly using username/password input, the system uses fingerprint verification as a mediator to trigger automatic credential retrieval, thereby reducing login time while preserving security through biometric authentication.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If fingerprint authentication is implemented, then login speed is improved, but system complexity increases

Engineering Contradiction:
Improvelogin speedVSAvoidauthentication system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by making the fingerprint authentication system serve multiple functions: it acts as both a security verification mechanism and a trigger for automatic credential retrieval. This multi-functionality allows the system to improve login speed without requiring separate complex modules for each function, thereby managing system complexity while enhancing productivity.

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

3Ease of operation

If automatic login is used, then login convenience is improved, but information security is compromised

Engineering Contradiction:
Improvelogin convenienceVSAvoidinformation security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by implementing different authentication mechanisms for different security requirements. Fingerprint recognition is used for the critical security verification step, while automatic retrieval is used for convenience. This differentiated approach ensures that security-critical operations maintain high reliability while non-critical operations benefit from improved ease of operation.

Inventive Principle:
Principle #3Local quality

AI summary

The present invention discloses a mobile terminal and an application program login method thereof. The method includes acquiring the to-be-authenticated fingerprint information inputted by a user when the user is required to log into an application program; determining whether the to-be-authenticated fingerprint information is the same as a correct fingerprint information which is locally preset and corresponds to the application program; if yes, then acquiring, according to the identifying fingerprint information, a user name and a password corresponding to the application program from a login information file which is locally preset; and logging into the application program according to the user name and the password. By logging into the application program via fingerprint, the present invention not only ensures the security of personal information, but also allows the user to quickly log into the application program, thereby improving user experience.
