Fingerprint Authentication for Mobile App Login Security
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Productivity
If fingerprint authentication is implemented, then login speed is improved, but system complexity increases
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.
3Ease of operation
If automatic login is used, then login convenience is improved, but information security is compromised
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.

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.
