Image Metadata Encoding for Secure Storage and Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional security software often fails to provide a direct recovery path for original images that have been replaced in a computing device's image album, making it difficult for users to retrieve sensitive content when they forget which images were replaced.
Innovation Solution
The method involves identifying image files in a public folder, storing a copy in a secure data storage application, encoding metadata to reveal the image, masking the image with encoded metadata to prevent sharing, and decoding the metadata to render the unmasked image upon request, ensuring secure and recoverable storage of sensitive images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security software replaces sensitive images with generic images in the device image album, then security against unauthorized sharing is improved, but the ability to retrieve original images is lost
Solution Approach 1:
The patent extracts the sensitive image data from the public image album and stores it separately in a secure container with encrypted metadata. The public album contains only placeholder or generic images, while the original sensitive images are removed to a protected location, preventing unauthorized access while preserving the ability to retrieve them through authenticated requests.
Solution Approach 2:
The patent introduces metadata as an intermediary between the user and the sensitive images. This metadata contains encoded information about the original images and serves as a key that can be used to retrieve the full-resolution or unmasked versions from secure storage, without exposing the actual image content in the public album.
2Reliability
If security software masks images to prevent viewing, then unauthorized access is prevented, but users cannot recover their original content when forgotten
Solution Approach 1:
The system enables users to retrieve their own masked images through self-service mechanisms. By providing tools that allow users to search for and recover their masked content using authentication credentials or associated metadata, the system eliminates the need for customer support intervention while maintaining security.
Solution Approach 2:
The patent implements feedback mechanisms where the system provides information about masked images to authorized users. Through metadata that contains searchable information about the masked content, users can identify what they have masked and retrieve it when needed, creating a feedback loop between the security system and the user.
3Reliability
If images are replaced with generic images in the public folder, then sharing security is improved, but the public folder size is reduced and original content is lost
Solution Approach 1:
The patent creates copies of sensitive images and stores them in secure storage locations, while the public folder contains either generic placeholder images or masked versions. The original high-quality images are copied to protected storage, allowing the public folder to maintain a smaller size while the secure copies preserve the original content for authorized retrieval.

AI summary
The disclosed computer-implemented method for utilizing metadata for protecting against the sharing of images in a computing network may include (i) identifying an image file stored in a public folder on a computing device, (ii) storing a copy of the image file within a secure data storage application, (iii) encoding metadata for revealing an image in the image file, (iv) performing a security action that protects against sharing the image file from the public folder by masking the image in the image file with the encoded metadata, and (v) rendering the image in the image file as an unmasked version of the image from the image file or the copy of the image file in the secure data storage application by decoding the metadata utilized to mask the image. Various other methods, systems, and computer-readable media are also disclosed.
