Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in managing and securing private photos and videos captured by mobile devices, as they are often automatically uploaded to cloud servers, risking exposure to unauthorized individuals.
Innovation Solution
An electronic device with a controller that performs codec processing and privacy detection on captured images or videos, encrypting files containing privacy information to prevent unauthorized access and upload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If photos are automatically uploaded to cloud server for convenient storage and management, then storage accessibility and convenience are improved, but security and privacy protection deteriorate
Solution Approach 1:
The system performs privacy detection and encryption on images before they are uploaded to the cloud server. The controller detects whether captured images contain privacy information, and if so, encrypts them using a preset encryption algorithm before automatic upload, thus preventing potential privacy exposure while maintaining the convenient automatic storage function
Solution Approach 2:
The patent introduces an intermediary processing mechanism between image capture and cloud upload. The controller acts as an intermediary that intercepts images, performs privacy detection, conditionally encrypts them, and then proceeds with upload. This intermediary layer ensures privacy protection without completely blocking the automatic upload function
2Object-affected harmful factors
If privacy detection and encryption are performed on all captured images, then security and privacy protection are improved, but processing time and computational resources increase
Solution Approach 1:
The system does not encrypt all captured images, but only those detected to contain privacy information. The controller performs privacy detection first, and only applies encryption to images that meet the privacy criteria, thus avoiding unnecessary processing time and computational resource consumption on non-sensitive images
Solution Approach 2:
The system implements a feedback mechanism where the privacy detection result directly controls whether encryption is applied. The controller receives feedback from the privacy detection module about whether an image contains sensitive content, and based on this feedback, dynamically decides to encrypt or not encrypt the image, optimizing processing efficiency

AI summary
An electronic device is provided. The electronic device includes a controller, configured to receive an input image signal captured by a camera device, perform a codec process on the input image signal to generate a processed file. The controller is further configured to perform privacy detection on the input image signal or the processed file. In response to the input image signal or the processed file being detected to include privacy information, the controller is further configured to encrypt the processed file to generate an encrypted file.
