Image Privacy Tagging in Storage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack effective privacy features for managing and distributing captured images, leading to inefficient resource management and unauthorized access.
Innovation Solution
An image processing application configures images as private by generating a metadata table with a privacy tag, determining a privacy value, and storing the image with the metadata in a local or cloud-based storage container, allowing access control based on the privacy value, which can be set to either private or public.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no privacy features are embedded in captured images, then distribution and access are simple and unrestricted, but unauthorized access occurs and resource management becomes inefficient
Solution Approach 1:
The patent applies preliminary action by embedding privacy tags and metadata into images at the moment of capture, before any distribution or access requests occur. This pre-configuration of privacy settings ensures that access control is automatically enforced without requiring complex real-time authorization systems, thus improving reliability while minimizing added complexity.
Solution Approach 2:
The patent introduces metadata tables and privacy tags as intermediary elements between the image data and access requests. These intermediaries carry privacy information that mediates access control decisions, allowing the system to enforce privacy rules without requiring direct complex communication between all parties, thereby improving access control reliability with minimal complexity overhead.
2Reliability
If privacy tags are embedded in all images, then unauthorized access is prevented, but processing and storage requirements increase
Solution Approach 1:
The patent segments privacy information into separate metadata tables rather than embedding it directly in the image data. This segmentation allows the privacy tags to be processed independently from the main image content, reducing the processing energy required for each operation while maintaining comprehensive privacy protection across all images.
Solution Approach 2:
The patent uses metadata tables that can be copied and referenced multiple times without duplicating the actual privacy control logic. Instead of processing privacy rules repeatedly for each access request, the system copies metadata references, significantly reducing processing energy consumption while maintaining reliable privacy protection.
3Reliability
If manual privacy configuration is required for each image, then precise access control is achieved, but user operation time increases
Solution Approach 1:
The patent implements self-service by enabling automatic privacy tag generation based on image metadata such as location, timestamp, and device information. The system automatically configures privacy settings without requiring manual user input for each image, thus maintaining precise access control while eliminating configuration time overhead. Users can override these automatic settings when needed.
4Reliability
If images are stored without privacy metadata, then storage operations are fast and simple, but third party access cannot be properly restricted
Solution Approach 1:
The patent uses metadata tables as intermediary structures that store privacy information separately from the main image data. This intermediary approach allows storage operations to remain efficient by storing only lightweight metadata references, while still enabling comprehensive third-party access control through the embedded privacy tags in the metadata.
Solution Approach 2:
The patent extracts privacy control information from the main image data and places it in separate metadata tables. This extraction allows the bulk storage operations to proceed quickly with minimal overhead, while the extracted privacy metadata maintains precise third-party access control restrictions without impacting storage efficiency.
Data Source
AI summary
An image is configured as private within a storage container. An image processing application initiates operations to configure the image as private upon receiving the image captured by an image capture device. A metadata table is generated for the image. The metadata table includes a privacy tag. A privacy value is determined for the privacy tag. Next, the privacy tag is configured based on the privacy value. The privacy tag determines an access to the image based on the privacy value. The image is stored with the metadata table in a storage container. The storage container is hosted locally or in a cloud based storage.
