Image Encoding and Blurring for Secure Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices and servers face challenges in securely transmitting and restoring images, as existing technologies do not effectively protect images from unauthorized access by encoding them in a way that ensures only authorized users can decode and view the original content.
Innovation Solution
An electronic device and server system that encodes images using security information to create code information, blurs the images, and transmits this encoded version, allowing only authorized users to decode and restore the original image using corresponding security information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images are transmitted in original form, then image quality is maintained, but security and privacy are compromised
Solution Approach 1:
The patent applies preliminary action by encoding the image with security information and blurring it before transmission. This preprocessing ensures that the image is protected against unauthorized access before it leaves the device, while still allowing authorized users to restore it later using their credentials.
Solution Approach 2:
The patent changes the state of the image from clear to blurred through encoding with security information. This parameter change transforms the image into an unreadable form for unauthorized users while maintaining the ability to restore it to its original state for authorized users who provide correct credentials.
2Reliability
If images are encoded with security information, then unauthorized access is prevented, but transmission and processing complexity increases
Solution Approach 1:
The system uses the user's existing security credentials (password, biometric data, or other authentication information) that they already possess to encode and decode their own images. This self-service approach eliminates the need for separate complex encoding keys or additional security hardware, as the user's existing authentication mechanisms serve dual purposes.
3Reliability
If images are blurred for security, then privacy is protected, but image usability for authorized users is reduced
Solution Approach 1:
The system implements feedback by using the same security information that proves user authorization to also serve as the key for restoring the blurred image. When an authorized user provides their credentials, the system verifies them and uses that verified information to decode and restore the image, creating a closed-loop authentication and restoration process.
