Video Reception Switching After Tamper Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video data tampering detection systems fail to ensure the reception of untampered video data after tampering is detected, as they do not provide mechanisms to continue receiving or protect untampered data.
Innovation Solution
A video transmission and reception system that generates and attaches a digital signature to video data using a hash value, allowing the client to detect tampering and respond by changing delivery methods or recording settings to ensure untampered data is received, including encryption, machine learning, and multimodal analysis for tampering detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data tampering detection is implemented using digital signatures and hash values, then tampering detection capability is improved, but the system cannot receive untampered video data after tampering is detected
Solution Approach 1:
The video delivery system dynamically switches between different delivery methods based on tampering detection results. When tampering is detected in the first delivery method, the system transitions to a second delivery method to continue receiving untampered video data, making the system adaptive rather than static
Solution Approach 2:
The system changes the delivery method parameter when tampering is detected. By altering the delivery approach (e.g., switching from one transmission path or protocol to another), the system maintains video data reception while avoiding tampered data streams
2Reliability
If the system stops receiving video data when tampering is detected, then video data integrity is protected, but video reception continuity is lost
Solution Approach 1:
The video reception system dynamically adjusts its operation mode based on tampering detection. Instead of simply stopping reception, it transitions to an alternative delivery method, maintaining continuous operation while protecting data integrity
Solution Approach 2:
A second video delivery method acts as an intermediary solution when the first method is compromised. This alternative path mediates between the need for continuous reception and the requirement for data integrity, allowing the system to bypass tampered data streams

AI summary
A video reception apparatus configured to communicate with a video transmission apparatus using at least a first method includes one or more processors, and one or more memories storing instructions that, when executed by the one or more processors, cause the one or more processors to function as a reception unit configured to receive video data via the communication using the first method, a determination unit configured to determine whether the received video data has been tampered with, and a transmission unit configured to transmit, to the video transmission apparatus, a command to start communication using a second method different from the first method in a case where the received video data is determined to have been tampered with.
