Digital Media Authenticity Verification via Capture Mode Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively verify the authenticity of digital media, such as photos and videos, which can be easily manipulated using techniques like deepfakes and augmented reality, making it difficult to trust the origin and integrity of media content.
Innovation Solution
A client-server system that verifies the authenticity of media by transmitting instructions to a capturing device to implement specific operation modes, such as changing frame rates or activating actuators, and checking if the media reflects these changes, making it hard to manipulate the media without detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media is captured and shared using accessible devices and applications, then ease of operation and accessibility are improved, but vulnerability to manipulation and loss of authenticity increases
Solution Approach 1:
The system performs preliminary actions by embedding verification data (such as digital signatures, metadata, or cryptographic hashes) into the media at the moment of capture. This preliminary authentication mechanism ensures that the media's origin and integrity are verified before sharing, preventing later manipulation while maintaining ease of use for end users.
Solution Approach 2:
The system implements feedback mechanisms where verification results are provided to users about the authenticity of media. This feedback loop allows users to know whether media has been manipulated, maintaining trust while preserving the accessibility of media capture and sharing operations.
2Adaptability or versatility
If media manipulation techniques like deepfakes and augmented reality are used, then versatility and adaptability of media creation are improved, but detection difficulty and reliability of verification worsen
Solution Approach 1:
The system embeds verification data at capture time that serves as a baseline for detecting later manipulations. This preliminary action creates an authentic reference that can be compared against the media to detect any subsequent alterations, including sophisticated manipulations like deepfakes and augmented reality modifications.
Solution Approach 2:
The system applies preliminary anti-action by pre-marking authentic media with verification data that actively counters manipulation attempts. This verification data acts as a protective measure that makes it difficult for manipulators to alter media without detection, thereby maintaining verification reliability despite increased versatility in media creation tools.
3Reliability
If verification mechanisms are implemented to ensure media authenticity, then reliability of media verification is improved, but device complexity and processing requirements increase
Solution Approach 1:
The system extracts the complex verification processing from end-user devices and concentrates it on server-side infrastructure. Capture devices only perform simple operations like embedding verification data or generating hashes, while the computationally intensive verification and analysis are performed remotely, reducing device complexity while maintaining high reliability.
Solution Approach 2:
The system introduces an intermediary verification service that mediates between media capture and authentication. This intermediary layer handles the complex verification logic, allowing capture devices to remain simple while ensuring reliable authentication through a dedicated verification infrastructure.

AI summary
Method, system and computer program product, the method comprising: during a streaming session of a media by a capturing device to the processing platform, transmitting to the capturing device an instruction to implement an operation mode when capturing a second portion of the media; receiving from the capturing device the media, wherein the media comprises at least a first portion and the second portion; and verifying authenticity of the media, wherein said verifying is based on a determination that the second portion of the media complies with the operation mode.
