Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fingerprint authentication in mobile devices is vulnerable to fraudulent methods, as users inadvertently leave fingerprints on various surfaces, allowing criminals to mimic them and gain access to devices and accounts.
Innovation Solution
A computerized method that combines fingerprint data collection with heartbeat data verification using optical sensors, where fingerprint data is matched against stored data, and heartbeat detection is used to confirm the presence of a heartbeat, ensuring secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fingerprint authentication is used, then user-friendly fast authentication is achieved, but security against fraudulent use deteriorates
Solution Approach 1:
The patent combines fingerprint authentication with heartbeat detection into a unified authentication system. The optical sensor simultaneously captures both fingerprint pattern data and heartbeat physiological data, merging two authentication modalities into a single integrated process that maintains user convenience while significantly improving security against spoofing attacks.
Solution Approach 2:
The patent introduces heartbeat detection as an intermediary verification layer between the fingerprint sensor and authentication approval. The heartbeat signal serves as a mediator that confirms the authenticity of the fingerprint by detecting genuine physiological activity, thereby preventing fraudulent authentication while maintaining the user-friendly interface.
2Reliability
If additional authentication methods are added, then security is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional optical sensor that performs both fingerprint pattern recognition and heartbeat detection using the same hardware infrastructure. This universal sensor design allows the system to implement enhanced security through multiple authentication modalities without proportionally increasing device complexity, as a single sensor component executes multiple authentication functions.
Solution Approach 2:
The patent merges fingerprint sensing and heartbeat detection into a single integrated sensor system that operates simultaneously. By combining these functions in one hardware platform rather than using separate sensors, the system achieves improved security through multi-factor authentication while minimizing the increase in device complexity through shared hardware resources.

Function Achieved in This Case
This approach provides a secure and user-friendly authentication method that is resistant to fingerprint exploitation, reducing reliance on slower or less secure authentication methods like passwords, while streamlining the authentication process.
Implementation Method 1
collecting, via an optical heartbeat sensor, heartbeat data from the digit based on light projected from a light source
Data Source
AI summary
The methods described herein are configured for authenticating a user identity. Fingerprint data is collected from a digit via a fingerprint sensor and heartbeat data is collected from the digit, via an optical heartbeat sensor, based on light projected from a light source. The collected fingerprint data is verified by comparison to stored fingerprint data associated with the user identity. The collected heartbeat data is used to detect the presence of a heartbeat. Based on a successful verification of the collected fingerprint data and a successful detection of the heartbeat, the user identity is authenticated. Authenticating the user identity based on both fingerprint data and heartbeat data enhances the security of the authentication process by preventing fraudulent use of fingerprints.
