Content Provenance Verification for Trusted Image Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to determine whether digital images are edited by a valid user or tampered by an invalid user, and do not verify the authenticity of the image itself being generated by a reliable imaging apparatus.
Innovation Solution
A content management apparatus that includes units for receiving, storing, and determining the authenticity of content based on provenance information and verification results, using hash values and digital signatures to ensure the image is generated by a reliable device and has valid edits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hash value verification is used to detect image tampering, then tampering detection capability is improved, but the ability to verify user validity and content authenticity is insufficient
Solution Approach 1:
The verification system is divided into multiple independent modules: a content generation module that creates content with embedded user identification information, a content distribution module that manages content delivery, and a verification module that checks both tampering and user validity. This segmentation allows each module to specialize in specific verification tasks, enabling comprehensive authenticity verification while maintaining system reliability.
2Loss of information
If metadata is added to indicate editing content, then editing information is preserved, but the ability to verify original content authenticity is lost
Solution Approach 1:
User identification information and authenticity markers are embedded in the content during the generation phase, before any editing or distribution occurs. This preliminary embedding ensures that the original creator's identity is permanently associated with the content, allowing verification of both the original authenticity and subsequent editing operations without loss of either information type.
3Adaptability or versatility
If content is distributed through multiple channels, then content reach is improved, but verification of content source authenticity becomes difficult
Solution Approach 1:
A content management apparatus acts as an intermediary between content generators and distributors. This apparatus verifies user identification information and content authenticity before allowing distribution through any channel. The intermediary maintains a record of verified content and its original source, ensuring that even when content is widely distributed, the verification of source authenticity remains reliable through centralized validation.

AI summary
The present disclosure is provided to enable determination of not only whether content is tampered by an invalid user but also whether an original content before change is the first content generated by a reliable content generation apparatus. A content management apparatus of the present disclosure receives content in content generation from the content generation apparatus and stores the generated content in a storage device. The content management apparatus acquires content to be determined and provenance information added to the content from a user terminal. The content management apparatus determines authenticity of the content to be determined based on whether the content in content generation corresponding to the content to be determined is stored in the storage device and a result of verification based on the provenance information. The content management apparatus notifies the user terminal of a result of determination.
