Home Gateway Content Backup with Privacy Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of apparatus and methods for automatically backing up content generated from mobile terminals and cameras in home network systems, as well as for selectively storing and classifying content based on user-set information to protect privacy.
Innovation Solution
A content backup method and apparatus for a home gateway that receives control commands from mobile terminals or cameras, automatically backing up content while excluding it from backup if it meets predetermined conditions, and allows for user-set criteria such as location and memo-based exceptions for privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic backup of all content is implemented, then backup completeness is improved, but user privacy is compromised due to inclusion of sensitive content
Solution Approach 1:
The patent extracts sensitive content from the overall backup process by identifying and excluding specific content types (photos, videos, audio files) that contain personal information. The home gateway detects content metadata and filters out sensitive items before backup, ensuring they are not stored in the cloud, thus protecting user privacy while maintaining backup of non-sensitive content.
Solution Approach 2:
The patent applies different backup policies to different content based on their sensitivity. Non-sensitive content is backed up automatically, while sensitive content is excluded. This local differentiation of backup quality allows the system to maintain high backup completeness for safe content while protecting privacy for sensitive content through selective exclusion.
2Object-affected harmful factors
If selective exclusion of content from backup is implemented, then user privacy is protected, but backup completeness deteriorates
Solution Approach 1:
The patent performs preliminary identification and classification of content sensitivity before the backup process begins. The home gateway analyzes content metadata (file types, tags, user-defined categories) in advance to determine which content should be excluded, allowing users to review and adjust exclusion criteria before actual backup occurs, thus maintaining transparency and control.
3Measurement precision
If manual review of each content item is required for backup decisions, then backup accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent implements automatic content classification and sensitivity detection by the home gateway without requiring user intervention for each content item. The system uses metadata analysis, file type recognition, and user-defined rules to automatically determine which content to backup and which to exclude, significantly reducing operation complexity while maintaining accurate backup decisions.
Solution Approach 2:
The patent provides feedback mechanisms where users can review the automatically classified sensitive content, adjust exclusion criteria, and provide corrections. This feedback loop allows the system to learn from user preferences and improve its automatic classification accuracy over time, balancing automation with user control.

AI summary
According to the present invention, content generated from a mobile terminal, a camera, or the like is stored automatically in a home gateway in a home network system. If synchronization is set between the home gateway and a home device, the home gateway may transmit backup content to the synchronized home device. Content may be selectively stored and classified based on a specific location, memo, voice, and the like set by a user for privacy protection.
