Video Source Authentication via Frame Identification Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media outlets face challenges in authenticating the source of video segments captured by private citizens, especially when these segments are transmitted over communication networks, due to the lack of reliable methods to verify the origin and integrity of the content.
Innovation Solution
A method is introduced where video segments received over a communication network are marked with identification data, allowing for the authentication of the source device, and access information is transmitted for accessing the marked video segment, utilizing a communication node with storage and control logic to manage and verify the video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video segments are transmitted over communication networks from private citizen devices, then media outlets can obtain additional video content for news coverage, but the ability to authenticate the source device and verify content integrity is compromised
Solution Approach 1:
The system embeds identification data from the source device into the video segment before transmission occurs. This preliminary marking of the video content with authenticating information allows media outlets to verify the source and integrity of received video segments without requiring additional authentication infrastructure at the time of reception.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where identification data serves as a mediator between the source device and the media outlet. This identification data, embedded within the video segment, acts as a trusted intermediary that carries authentication information through the communication network, enabling verification without direct connection between source and outlet.
2Reliability
If identification data is embedded in each frame of the video segment, then source authentication and tampering detection are enabled, but the data processing and storage requirements increase
Solution Approach 1:
The authentication system divides the video content into discrete frames, with identification data embedded in each frame. This segmentation allows for frame-level authentication and tampering detection, where individual frames can be verified independently. The identification data is broken down and associated with specific frame identifiers, enabling granular verification without requiring complex whole-video analysis.
Data Source
AI summary
A method is provided for authenticating a source device transmitting a video segment. In the method, the video segment is received from the source device over a communication network. The video segment comprises a number of frames. Identification data indicating the source device is also received over the communication network. Each of the frames of the video segment is marked with a form of the identification data. Access information is transmitted over the communication network for accessing the marked video segment.
