Dynamic Scene Changing Element for Video Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a more secure method to detect unauthorized tampering of real-time video feeds in the video security context, as existing technologies are inadequate in verifying the authenticity and integrity of streaming video data.
Innovation Solution
A system that uses a dynamic scene changing element to alter the video data stream according to a unique sequence or pattern, allowing the system to compare expected scene changes with actual changes in the video stream, and take remedial measures if inconsistencies are detected, such as generating an alert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional video security systems are used to monitor real-time video feeds, then the system is simple and easy to operate, but the system cannot detect unauthorized tampering or verify the authenticity of video data
Solution Approach 1:
The patent introduces a scene changing element as an intermediary object within the monitored scene that actively modifies the video feed by changing its visual characteristics (color, position, shape) according to a predetermined pattern. This intermediary element serves as a reference marker that allows the system to verify video authenticity without fundamentally redesigning the entire video security infrastructure
Solution Approach 2:
The system implements feedback by continuously comparing the observed scene changes (caused by the scene changing element) with expected scene changes (predetermined pattern). When the observed changes match the expected changes, the video is authenticated; when they diverge, tampering is detected. This feedback mechanism enables reliability improvement through continuous verification
2Reliability
If a dynamic scene changing element is introduced to authenticate video streams, then the system can detect tampering and verify authenticity, but the device complexity and difficulty of operation increase
Solution Approach 1:
The scene changing element operates autonomously according to a predetermined pattern, automatically modifying the video scene without requiring manual control or intervention. The element self-manages the scene changes, and the system automatically compares observed changes with expected changes, eliminating the need for complex manual operation while maintaining high reliability
3Reliability
If scene change detection is implemented to verify video integrity, then unauthorized tampering can be detected, but the measurement precision and detection difficulty increase
Solution Approach 1:
The patent utilizes color changes as a primary mechanism for the scene changing element to modify the video scene. By changing visual characteristics such as color, the element creates distinct, easily measurable differences in the video feed that can be accurately detected and compared against expected patterns, simplifying the measurement process while maintaining high detection precision

AI summary
The present disclosure is directed to a novel system that uses a dynamic scene changing element to authenticate real-time video data. In particular, the dynamic scene changing element may alter the video data stream collected a video input device according to a sequence or pattern that is unique for a given timeframe. The system may then compare the expected video stream (based on scene changes created from the unique pattern) with the current video stream. If the system detects that the dynamic scene changes are incorrect or missing, the system may determine that the real-time video data is not authentic, and subsequently take remedial measures. In this way, the dynamic scene changing element allows the system to determine whether the real-time streaming video data is reflective of the current or “true” state of the scene as captured by the video input device.
