Chain-of-Manipulation Tracking for Audio-Video Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The unauthorized manipulation of audio-video content is difficult to detect, leading to potential legal jeopardy for content owners and distributors, as subtly altered or fake content may be inadvertently used instead of original content, violating contractual and regulatory restrictions.
Innovation Solution
A method for tracking the chain-of-manipulation of AV content using CoM tags, which include application tags, origination tags, and persistent metadata, inserted into specific frames of the content, allowing for automated detection and authentication of modifications, ensuring the integrity and authenticity of the content across various devices and platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AV content is manipulated through editing applications, then artistic or legitimate modifications can be made, but unauthorized manipulation becomes difficult to detect and may lead to legal jeopardy
Solution Approach 1:
The patent applies preliminary action by embedding authentication tags and metadata into the AV content during creation or authorized editing, before any potential unauthorized manipulation occurs. This proactive approach ensures that the content carries inherent authentication markers that can later verify its legitimacy and track its modification history, resolving the contradiction between allowing modifications and maintaining authenticity.
2Object-affected harmful factors
If AV content is substantially altered or replaced with fake content, then malicious manipulation occurs, but detection of such manipulation is typically difficult
Solution Approach 1:
The patent implements feedback by creating a traceable chain-of-manipulation through embedded tags that record each modification event. When AV content is manipulated, the system generates feedback in the form of authentication verification results that indicate whether the content has been authorizedly modified or tampered with. This continuous feedback mechanism enables detection of malicious manipulation while maintaining content integrity.
Solution Approach 2:
The patent uses authentication tags and metadata as intermediaries between the AV content and the verification system. These tags serve as mediators that carry authentication information and modification history, enabling the detection system to verify content integrity without directly analyzing the entire AV content. This intermediary approach makes manipulation detection feasible and reliable.
3Ease of operation
If authorized modifications are made to AV content, then legitimate editing can occur, but tracking the chain of manipulation becomes necessary to ensure compliance
Solution Approach 1:
The patent merges the authentication tracking functionality with the AV content itself by embedding tags and metadata directly into the content structure. This integration allows the tracking system to operate seamlessly with standard AV processing workflows without requiring separate complex tracking infrastructure. The authentication information is combined with the content in a way that maintains ease of operation while enabling comprehensive tracking.

AI summary
A device for use in a system for tracking a chain-of-manipulation (CoM) of audio-video (AV) content includes a hardware processor, and a system memory storing a CoM tagging software code and an AV processing application. The hardware processor executes the CoM tagging software code to detect manipulation of the AV content by the AV processing application that modifies at least one of video or audio of the AV content, and to generate, when the manipulation is detected, one or more CoM tag(s) including a device identification tag identifying the device used for modifying the AV content. The hardware processor also executes the CoM tagging software code to insert the CoM tag(s) in each modified segment of the AV content modified by the AV processing application, the inserted CoM tag(s) being human and machine imperceptible when the AV content is played back by a playback device on a display.
