Picture Sharing Apparatus with Level-Based Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing picture sharing technologies lack the ability to differentiate and control access to shared images based on user-defined sharing levels, often requiring either complete sharing or no sharing at all, failing to balance privacy protection with the desire to share content.
Innovation Solution
A picture sharing apparatus and method that differentiates images based on user-defined sharing levels by employing a storage unit, level determination unit, differentiation unit, and picture provider to adjust settings such as image definition, resolution, cropping, metadata display, and audio/video outputs according to the user's sharing level, allowing for nuanced control over shared content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pictures are shared through establishment of acquaintance relationships (such as friend relationships), then access control is simplified, but the ability to differentiate sharing levels is lost
Solution Approach 1:
The patent segments the binary access control (friend/not friend) into multiple sharing levels (first sharing level, second sharing level, third sharing level). Each level corresponds to different differentiation methods applied to pictures, enabling granular control over content accessibility while maintaining relationship-based authorization.
Solution Approach 2:
The system dynamically adjusts picture differentiation based on the sharing level of the requesting user. The differentiation unit selects different differentiation methods (blurring, cropping, resolution reduction) depending on whether the user is at the first, second, or third sharing level, making the access control mechanism adaptive rather than static.
2Device complexity
If pictures are completely shared or not shared at all, then access control is binary and simple, but privacy protection is insufficient for nuanced sharing needs
Solution Approach 1:
The patent applies local quality by selectively differentiating specific regions or attributes of pictures based on sharing levels. Instead of completely blocking or fully sharing entire pictures, the system applies different differentiation methods to different aspects of the picture (e.g., blurring faces while keeping bodies visible, or reducing resolution for certain regions), enabling nuanced privacy protection.
Solution Approach 2:
The system changes key parameters of picture quality (resolution, definition, cropping extent) based on the sharing level. The differentiation unit modifies these parameters dynamically when generating pictures for users at different sharing levels, transforming the binary access control into a multi-level system with graduated privacy protection.
3Adaptability or versatility
If multiple differentiation methods are applied to pictures, then sharing control is enhanced, but processing complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining multiple differentiation methods (first differentiation method, second differentiation method, third differentiation method) that correspond to different sharing levels. These methods are prepared in advance and selected based on the user's sharing level, avoiding the need for complex real-time decision-making during picture delivery.
Solution Approach 2:
The system creates differentiated copies of pictures for different sharing levels. Instead of modifying the original picture in place, the differentiation unit generates separate picture versions tailored to each sharing level, allowing multiple differentiation methods to coexist without interfering with each other and simplifying the processing architecture.

AI summary
A picture sharing apparatus and method are provided. The picture sharing apparatus includes technology for providing pictures differentiated according to sharing levels. The picture sharing technology may receive a picture request from a user's terminal and determine that user's sharing level and provide a picture differentiated in a predetermined form according to the user's sharing level. The picture sharing technology fulfills the two conflicting tasks of privacy protection and picture sharing.
