Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for image transmission and storage in biometric systems lack adequate security measures, leading to risks of information leakage and non-compliance with legal standards.
Innovation Solution
An image encryption method that processes pixel values of an original image based on the number of target devices to receive images, generating multiple first target images, which are then encrypted using a target key and sent to corresponding target devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If images containing users are directly transmitted and stored for subsequent recognition, then the recognition process can be performed efficiently, but it leads to information leakage risks and legal compliance issues
Solution Approach 1:
The patent divides the original image into multiple first target images by splitting pixel values into multiple sub-pixel values. Each first target image contains only part of the original image information, making it impossible to reconstruct the original image from a single encrypted image. This segmentation approach maintains recognition efficiency while preventing information leakage.
Solution Approach 2:
The patent introduces an intermediary encryption mechanism using target keys to protect the image data during transmission and storage. The encryption ensures that even though images are transmitted and stored, the actual image content remains protected, eliminating direct exposure of user information while enabling subsequent recognition operations.
2Reliability
If pixel values are split into multiple sub-pixel values to create multiple first target images, then security is improved, but the complexity of image processing increases
Solution Approach 1:
The patent segments pixel values into multiple sub-pixel values and distributes them across multiple first target images. This segmentation is implemented through systematic pixel value splitting and redistribution algorithms that, while increasing processing complexity, maintain a structured and manageable approach to security enhancement.
3Reliability
If multiple first target images are encrypted and sent to multiple target devices, then information leakage is prevented, but the transmission and storage requirements increase
Solution Approach 1:
The patent segments the original image into multiple first target images with reduced information content each. By distributing the image data across multiple devices and encrypting each segment separately, the system prevents information leakage while the total data volume remains manageable due to the segmented structure.
