Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video editing and check processes lack comprehensive trace recording and security, as they cannot ensure whole-process trace leaving for video clipping and tamper-proofing of manuscript editing information.
Innovation Solution
A method using key frames from video clipping information to generate histogram data, which is encrypted and stored on a blockchain with timestamps as nodes, forming a trace chain for comprehensive and secure video clipping trace leaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional methods are used to record traces of graphics and manuscripts, then the recording process is simple, but the trace record is not comprehensive and cannot be applied to whole-process trace leaving of consecutively video clipping
Solution Approach 1:
The video clipping process is segmented into discrete key frames that are extracted and recorded individually on the blockchain. Each key frame represents a specific moment in the video editing process, allowing comprehensive tracking of changes without requiring continuous recording of all video data.
Solution Approach 2:
Blockchain technology serves as an intermediary layer between the video editing system and the trace recording system. It mediates the storage and verification of video modification information, enabling comprehensive trace recording while maintaining system independence and reducing direct complexity.
2Reliability
If manuscript editing information is stored in a conventional database, then storage and retrieval are straightforward, but tamper-proofing and security of trace data cannot be guaranteed
Solution Approach 1:
The critical trace data (video modification information) is extracted from the conventional database storage model and transferred to the blockchain for secure storage. This separation allows the system to maintain simple database operations for routine tasks while ensuring security and tamper-proofing for critical trace data through blockchain's inherent security mechanisms.
3Loss of information
If key frame extraction and histogram generation are performed for every video clipping, then comprehensive trace information is captured, but processing time and computational resources increase
Solution Approach 1:
Key frames are extracted and histogram data is generated in advance during the video clipping process, before the actual blockchain recording occurs. This preliminary processing allows the system to capture comprehensive modification information efficiently, reducing the computational burden during the trace recording phase.
