Image Display Controller Local Viewing History for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in selecting content on image display apparatuses due to inaccurate recommendations, as existing methods rely on external servers collecting personal viewing history, leading to potential privacy concerns and incomplete content suggestions, especially when not logged in or for terrestrial broadcasting content.
Innovation Solution
An image display apparatus with a network interface, broadcast reception unit, memory, and controller that adds content information to a viewing history database, determines content priority based on user history, and recommends content through a display, using a camera to gather user features for personalized recommendations without relying on external servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external servers collect user viewing history for content recommendation, then content recommendation accuracy is improved, but user privacy security deteriorates
Solution Approach 1:
The patent extracts the viewing history data collection function from external servers and relocates it to the image display apparatus itself. The controller locally stores viewing history information in internal memory and performs content recommendation based on this local data, eliminating the need to transmit personal viewing history to external servers while maintaining recommendation accuracy.
Solution Approach 2:
The patent introduces an intermediary mechanism where the image display apparatus acts as a local mediator between user viewing behavior and content recommendation. Instead of direct external server access, the apparatus processes viewing history locally and generates recommendations internally, serving as a privacy-protecting intermediary that prevents direct exposure of user data to external parties.
2Measurement precision
If external servers collect comprehensive viewing history for content recommendation, then content recommendation accuracy is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges the viewing history storage function and content recommendation function into the image display apparatus itself. The controller integrates both the viewing history database and the recommendation algorithm within the device, eliminating the need for separate external server infrastructure and reducing overall system complexity.
Solution Approach 2:
The image display apparatus performs self-service by independently collecting, storing, and processing its own viewing history data to generate content recommendations. The controller autonomously manages the viewing history database and executes recommendation algorithms without requiring external server assistance, making the system self-sufficient and simpler in structure.
3Measurement precision
If user login is required for content recommendation service, then content recommendation accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent performs preliminary action by collecting and storing viewing history information automatically as users watch content, without requiring explicit login actions. The controller continuously accumulates viewing data in the background during normal content playback, preparing the recommendation database in advance so that recommendations are ready whenever users request them, eliminating login barriers.
4Measurement precision
If viewing history is stored externally for content recommendation, then content recommendation accuracy is improved, but loss of information deteriorates
Solution Approach 1:
The patent extracts the viewing history storage function from external servers and relocates it to local memory within the image display apparatus. This ensures that viewing history information remains permanently stored in the device unless explicitly deleted by the user, preventing external server outages, data breaches, or access restrictions from causing data loss.
