Multi-Screen Fingerprint Recognition via Cross-Device Template Reuse

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multi-screen electronic devices require users to repeatedly provide fingerprint information across different screens for recognition, leading to high user operation redundancy.

Innovation Solution

A fingerprint recognition method that involves obtaining first fingerprint information through one screen, extracting a pre-stored fingerprint template for another screen based on its recognition mode, and then verifying this template against fingerprint information obtained from the second screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fingerprint information is obtained through all screens in multi-screen electronic devices, then fingerprint recognition can be achieved on each screen, but user operation redundancy increases

Engineering Contradiction:

Improvefingerprint recognition capabilityVSAvoiduser operation redundancy

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by obtaining and storing fingerprint information from a first screen in advance. This pre-obtained fingerprint data is then reused for recognition on a second screen, eliminating the need for users to repeatedly provide fingerprint information and reducing operational redundancy while maintaining recognition capability across multiple screens.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements universality by making the fingerprint information obtained from the first screen applicable to multiple screens. The same fingerprint data serves recognition purposes on both the first and second screens, allowing one fingerprint capture to fulfill multiple recognition functions across different screens.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If different fingerprint recognition modules are arranged on different screens, then each screen can perform independent recognition, but the system complexity increases

Engineering Contradiction:

Improvescreen independenceVSAvoidmodule arrangement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies merging by consolidating the fingerprint recognition functionality across screens. Instead of requiring separate recognition modules on each screen, the system combines the fingerprint data from one screen and uses it for recognition on multiple screens, reducing the number of independent modules needed while maintaining screen independence for recognition operations.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A fingerprint recognition method that is performed by an electronic device including a first screen and a second screen includes: obtaining first fingerprint information through the first screen; extracting a first fingerprint feature from the first fingerprint information based on a fingerprint recognition mode corresponding to the second screen, and using the first fingerprint feature as a first pre-stored fingerprint template corresponding to the second screen; obtaining second fingerprint information through the second screen; and extracting a second fingerprint feature from the second fingerprint information, and determining whether the second fingerprint feature matches the first pre-stored fingerprint template.
