Solution Overview
Problem
Challenges exist in providing secure, real-time custom data selection and communication of multiple data points from IoT-enabled devices, such as vehicles, to data buyers while ensuring control and compensation for the device owners.
Innovation Solution
Utilizing an on-board computing resource like a Controller Area Network (CAN bus) to compile custom data selections requested by data buyers, secured by a Mobile Edge Computing (MEC) server, which applies hash functions and interacts with a decentralized entity like a blockchain to facilitate smart contracts for data exchange and reward transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom data selection and transmission from IoT devices is implemented, then data buyers can obtain specific valuable data, but security and control mechanisms increase system complexity
Solution Approach 1:
The patent introduces a computing device as an intermediary between the vehicle (edge device) and the decentralized entity (blockchain). This intermediary handles the complexity of smart contract execution, hash function application, and reward distribution, thereby enabling custom data selection capabilities without directly increasing the complexity of the vehicle's onboard systems. The computing device mediates the interaction, absorbing the computational and security overhead.
2Speed
If real-time data transmission is implemented, then data buyers receive timely information, but data integrity and security verification increase processing time
Solution Approach 1:
The patent applies hash functions to the custom data selection before transmission to the decentralized entity. This preliminary action creates a cryptographic fingerprint of the data, enabling later verification of data integrity without requiring re-transmission or re-processing of the original data. The hash computation is performed in advance, allowing fast verification at a later stage while maintaining real-time transmission capabilities.
3Productivity
If device owners receive direct rewards, then compensation is streamlined, but smart contract execution and verification increase computational overhead
Solution Approach 1:
The computing device serves as an intermediary that executes the smart contract logic and manages reward distribution. Instead of requiring the vehicle's onboard computing resources to handle complex smart contract execution and verification, the computing device absorbs this computational overhead. This enables direct reward distribution to device owners while keeping the vehicle's energy consumption and computational burden minimal.
