Distributed Video Verification via Color and Audio Value Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively verify the authenticity and integrity of media files, particularly videos, which can be tampered with using computer applications or online tools, leading to potential errors in legal or surveillance contexts.
Innovation Solution
An electronic device and method for generating values from media files, including video and audio components, which retrieves color and audio values, combines them to create a unique information set stored across multiple databases, ensuring robustness against alterations and enabling accurate verification of media file authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media files are stored and verified using a single centralized database, then the verification process is simple, but the system becomes vulnerable to tampering and compromise
Solution Approach 1:
The patent divides the verification system into multiple independent databases distributed across different locations or entities. Each database stores a portion of the verification data, so that no single point of failure or compromise can invalidate the entire verification system. This segmentation increases reliability by ensuring that even if one database is tampered with, the other databases remain intact and can still verify authenticity.
2Measurement precision
If the entire media file is analyzed for verification, then the verification accuracy is high, but the processing time and computational resources increase significantly
Solution Approach 1:
The patent extracts specific identifying features or characteristics from the media file that can serve as verification markers. Instead of analyzing the entire media file, the system identifies and extracts key elements (such as metadata, digital signatures, or specific frame characteristics) that are sufficient for authenticity verification. This extraction process maintains high verification accuracy while dramatically reducing processing time and computational resource requirements.
3Reliability
If verification data is stored in a single location, then the storage and retrieval process is efficient, but the system lacks robustness against data loss or compromise
Solution Approach 1:
The verification data is segmented and distributed across multiple storage locations or databases. Each database holds a portion of the verification information, creating a redundant system where data integrity can be maintained even if one storage location is compromised or experiences data loss. The system retrieves verification data by querying multiple databases, ensuring robustness against single-point failures.
4Measurement precision
If the system verifies every media file in detail, then the detection of tampering is accurate, but the productivity and throughput of the system decrease
Solution Approach 1:
The system extracts and verifies only the critical identification features of each media file rather than performing detailed analysis of the entire file. This extraction-based approach maintains high accuracy in detecting tampering by focusing on the most significant verification markers, while significantly improving verification throughput by reducing the amount of data that needs to be processed for each file.
Data Source
AI summary
An electronic device and a method for value generation for distributed video content verification are disclosed. The electronic device receives a first media file corresponding to a video. The electronic device retrieves color values of each row in a frame of a plurality of frames from the video. The electronic device determines a first value for each row in the frame. The electronic device combines the first value for a predefined set of frames to determine a second value. The electronic device retrieves audio values for the plurality of frames to determine a third value, in case the video includes an audio component. The electronic device determines first information based on the second value and the third value. The electronic device transmits the first information to a plurality of databases for storage. The first information determines whether a second media file is unaltered or not.
