Image Sensor Biometric Authentication Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication systems using mobile terminals face security risks due to the transmission of unencrypted biometric information between the terminal and an image processing server, which can lead to potential information leakage.
Innovation Solution
An image sensor with integrated biometric information acquisition, storage, and authentication units, along with an encryption processing unit that encrypts and outputs biometric authentication information, allowing for secure comparison and authentication within the sensor, thereby reducing the risk of information leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information is transmitted to an image processing server for authentication, then authentication functionality is achieved, but security of biometric information deteriorates due to potential monitoring and leakage during transmission
Solution Approach 1:
The patent extracts the biometric information processing function from the external server and relocates it to the image sensor itself. The image sensor now performs authentication locally by comparing captured biometric data with reference data stored in its internal memory, eliminating the need to transmit sensitive biometric information externally and thus resolving the security contradiction.
Solution Approach 2:
The patent introduces an encryption processing unit as an intermediary between the biometric information acquisition and output stages. This unit encrypts the biometric authentication information before it leaves the image sensor, adding a security layer that protects the information even during necessary external communications, thus maintaining both functionality and security.
2Object-affected harmful factors
If biometric information is encrypted during transmission, then security is improved, but complexity of the system increases due to additional encryption components and processes
Solution Approach 1:
The patent merges the encryption processing unit within the image sensor device itself, combining multiple functions (biometric acquisition, authentication, and encryption) into a single integrated sensor module. This consolidation achieves the security benefits of encryption while minimizing overall system complexity by eliminating the need for separate external authentication servers and complex transmission protocols.
3Adaptability or versatility
If biometric authentication is performed outside the mobile terminal using an image processing server, then authentication capability is achieved, but risk of information leakage increases due to data transmission vulnerabilities
Solution Approach 1:
The patent extracts the biometric authentication function from external servers and embeds it directly within the image sensor. The sensor now stores reference biometric data in its internal memory and performs authentication comparisons locally, completely eliminating the need to transmit biometric information to external servers and thus preventing information leakage during transmission.
Solution Approach 2:
The image sensor becomes self-sufficient by performing biometric authentication internally without requiring external server assistance. It autonomously compares captured biometric data with stored reference data and generates authentication results, making the system independent of external infrastructure and eliminating transmission-related security vulnerabilities.
