Blockchain Video Evidence Sharing for Multi-Transport Accident Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient and secure method to collect, share, and store video data from multiple transports involved in accidents, which is essential for identifying fault parties but is hindered by the inability to automatically share videos between vehicles and with authorities.
Innovation Solution
A blockchain-based system that allows transports involved in accidents to query and access video data from other transports within the accident's location and time parameters, using smart contracts to ensure secure and consensus-based data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data from multiple transports is collected and stored centrally, then the ability to identify fault parties is improved, but the system complexity and data security risks increase
Solution Approach 1:
The patent segments the centralized video storage system into decentralized storage across multiple transports. Each transport stores its own video data locally, and the blockchain distributes the indexing and access control information across multiple nodes. This eliminates the need for a single centralized server while maintaining the ability to retrieve relevant video data from multiple sources during accident investigation.
Solution Approach 2:
The patent introduces a blockchain as an intermediary layer between transports and the accident processing authority. The blockchain smart contract mediates the access requests by verifying permissions, locating relevant video data across distributed transports, and facilitating secure data retrieval. This intermediary simplifies the system architecture by abstracting the complexity of distributed data location and access control.
2Productivity
If automatic video sharing between transports and authorities is enabled, then the accident processing efficiency is improved, but the data privacy and security concerns increase
Solution Approach 1:
The patent implements preliminary action through pre-configured smart contracts that define access permissions and data sharing policies before accidents occur. These smart contracts automatically execute when accidents are detected, enabling rapid video data sharing without manual intervention while maintaining privacy through predefined access control rules. The system prepares and enforces data sharing protocols in advance, eliminating the need for ad-hoc decisions during emergency processing.
Solution Approach 2:
The patent uses parameter changes in the blockchain smart contracts to dynamically control data access based on accident severity, user permissions, and legal requirements. The system can modify access parameters such as who can view the video data, how long the data is retained, and what notifications are sent, allowing flexible privacy protection that adapts to different accident scenarios while maintaining processing efficiency.
Data Source
AI summary
An example operation may include one or more of querying, by a transport, a plurality of transports within a range of an accident location, receiving, by the transport, agreements to access profiles of the plurality of transports on a storage, and responsive to the profiles containing video data associated with the accident location, linking the video data to a profile of the transport.
