Multi-Fingerprint Touch Screen Authentication for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint recognition technologies using a single fingerprint for unlocking mobile devices have inadequate security, leading to vulnerabilities in protecting confidential information and accounts, especially for high-security applications.
Innovation Solution
A fingerprint recognition method and device for touch screens that utilize at least two preset fingerprint codes, including a user identification fingerprint group and an SOS fingerprint group, allowing multiple fingerprints to be inputted in a sequence, which are compared to execute specific operations such as unlocking or activating a secret SOS mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single fingerprint is used for recognition, then the ease of operation is improved, but the security level deteriorates
Solution Approach 1:
The patent divides the fingerprint recognition into multiple segments by requiring a sequence of multiple fingerprints instead of a single fingerprint. The system divides the authentication process into multiple steps where each fingerprint contributes to the overall security, making it harder to crack while maintaining usability through sequential input.
Solution Approach 2:
The patent transitions from one-dimensional single-fingerprint recognition to multi-dimensional sequential fingerprint recognition. By adding the dimension of sequence order and multiple fingerprint combinations, the system dramatically increases the security space without significantly complicating the user interaction process.
2Reliability
If multiple fingerprint codes are used for recognition, then the security level is improved, but the device complexity increases
Solution Approach 1:
The patent makes the fingerprint recognition system multi-functional by enabling it to perform both normal unlocking operations and emergency SOS mode activation through the same multi-fingerprint sequence mechanism. This universal approach allows a single system to handle multiple security scenarios without requiring separate complex systems for each function.
Solution Approach 2:
The patent changes the parameter of fingerprint recognition from single fingerprint to multiple fingerprint sequences. By adjusting this key parameter, the system achieves enhanced security without proportionally increasing complexity, as the core recognition mechanism remains the same while only the input requirements change.
3Reliability
If multiple preset fingerprint codes are stored, then the security level is improved, but the loss of information increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring different fingerprint sequence patterns corresponding to different functions (normal unlocking vs. SOS mode). This allows the system to securely store multiple fingerprint codes while maintaining information security through structured organization and access control, reducing the risk of information leakage.

AI summary
A fingerprint recognition method and device for a touch screen, and a touch screen. The fingerprint recognition method for a touch screen includes: determining a fingerprint code input by a user; and comparing the fingerprint code input by the user with at least two pre-set fingerprint codes, and when the fingerprint code input by the user is the same as a fingerprint code in the at least two pre-set fingerprint codes, executing an operation corresponding to the fingerprint code. The fingerprint recognition method and device and the touch screen can improve the security of the touch screen, so as to ensure the personal and property safety of a user.
