Finger Vein Authentication in Biological Measurement Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological information measuring devices, such as those for blood sugar levels, face issues with patient privacy protection as unique IDs can be compromised, allowing unauthorized access to test results if the device is lost.
Innovation Solution
Incorporating a vein pattern measurement system where the vein pattern is used instead of a unique ID for authentication, ensuring that personal information is not stored on the device and can only be accessed through authentication by an external server, thus preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a unique ID is pre-set to the measuring device for patient identification, then patient identification and data transmission to the server are enabled, but patient privacy is compromised when the device is lost
Solution Approach 1:
The patent extracts the identification function from static device IDs and relocates it to dynamic biometric data (vein patterns). Instead of relying on a pre-set unique ID stored in the device, the system uses temporarily captured vein pattern information as the identification key, which is transmitted to the server for authentication. This extraction removes the vulnerable static identifier from the device while maintaining the identification capability.
Solution Approach 2:
The patent changes the identification parameter from a static device ID to dynamic biometric data (vein pattern). The vein pattern measurement results vary with each measurement and are tied to the user's physical characteristics rather than the device itself. This parameter change ensures that even if the device is lost, the stolen device cannot access personal information without the corresponding biometric authentication.
2Object-affected harmful factors
If no identification information is included in transmitted data, then privacy is protected, but the server cannot identify which patient the test result belongs to
Solution Approach 1:
The patent introduces vein pattern measurement results as an intermediary between the device and the server for identification purposes. Rather than transmitting personal identification information directly, the system uses the vein pattern data as a mediator that enables the server to authenticate and identify the patient without exposing sensitive personal information in the transmitted data.
3Reliability
If vein pattern measurement results are used for authentication instead of user ID, then personal information is not stored on the device, but the system complexity increases
Solution Approach 1:
The patent replaces the mechanical/storage-based identification system (storing user IDs and personal information in device memory) with an optical/biometric system (capturing vein patterns through light transmission). The vein pattern measurement unit uses light sources and light-receiving elements to capture biometric data, substituting the traditional storage-and-retrieval mechanism with a real-time biometric authentication mechanism that doesn't require storing sensitive personal information.

Function Achieved in This Case
This approach effectively protects patient privacy by ensuring that even if the device is lost, the personal information cannot be accessed by third parties, maintaining the confidentiality of user data.
Implementation Method 1
a first light source which emits, to the finger insertion part, first light having a first wavelength; a first light-receiving unit configured to receive first reception light which is the first light transmitted through the finger or reflected from the finger
Implementation Method 2
a second light source which emits, to the finger insertion part, second light having a second wavelength different from the first wavelength; a second light-receiving unit configured to receive second reception light which is the second light transmitted through the finger or reflected from the finger
Data Source
AI summary
A biological information measuring device includes a finger insertion part; a first light source which emits, to the finger insertion part, first light; a second light source which emits, to the finger insertion part, second light; and a first light-receiving unit which receives first reception light which is the first light transmitted through the finger or reflected from the finger. A second light-receiving unit receives second reception light which is the second light transmitted through the finger or reflected from the finger; a calculating unit measures a vein pattern of the user based on the first reception light, and measures biological data of the user based on the second reception light; and a transmitting and receiving unit transmits, to an external server, a measurement result of the vein pattern and a measurement result of the biological data.
