Fingerprint Template Matching for Screen-Off Application Launch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint identification technologies in mobile terminals lack convenience, quickness, and privacy protection, especially when transitioning between applications and modes, and do not efficiently manage screen states for seamless operation.
Innovation Solution
A method and system that pre-register fingerprints as templates associated with specific application operations, allowing for direct execution of associated tasks in both screen-on and screen-off states, with orientation-specific touches for different applications, modes, and system themes, enhancing convenience and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fingerprint identification is used for unlocking, then security is improved, but convenience and responsiveness are worsened due to additional unlocking steps required
Solution Approach 1:
The system pre-registers multiple fingerprint templates and associates each with specific application operations in advance. When a fingerprint is scanned, the system directly executes the pre-associated operation without requiring additional unlocking steps, thus maintaining security while improving convenience and responsiveness
2Productivity
If screen is kept on for quick access to applications, then responsiveness is improved, but energy consumption increases
Solution Approach 1:
The system performs fingerprint template matching and operation association in advance during screen-off state. When quick access is needed, the pre-prepared associations enable immediate execution of applications without requiring the screen to remain on, thus improving responsiveness while reducing energy consumption
3Ease of operation
If multiple applications are accessible without restrictions, then ease of use is improved, but privacy protection is worsened
Solution Approach 1:
The system segments access rights by creating multiple fingerprint templates, each associated with specific application operations. Different fingerprints can have different permission levels and access different sets of applications, enabling both ease of use for authorized users and privacy protection through fine-grained access control

AI summary
The present invention discloses a method and system for processing input fingerprint information, and a mobile terminal thereof. The method includes the following steps: a fingerprint information identification step: when it is scanned that fingerprint information is input, identifying whether a fingerprint template matching with the input fingerprint information is present in a fingerprint database, wherein the fingerprint database includes a plurality of pre-registered fingerprint templates, each fingerprint template being associated with an application operation; and an operation execution step: if it is identified that a fingerprint template matching with the input fingerprint information is present in the fingerprint database, performing the application operation associated with the identified fingerprint template. According to the present invention, a plurality of fingerprints are pre-registered as a fingerprint template, and then an application operation is set to be associated with each fingerprint template. In this way, no matter in a screen on or screen off state, the associated application may be started, such that a user experiences more convenient and quicker services. In addition, since various application operations are all associated with specific fingerprint information, the privacy is better protected.
