IoT Location Service Address Masking via Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based service technologies fail to adequately protect the privacy of IoT terminals by exposing their real addresses to service providers, compromising user data security.
Innovation Solution
A method and apparatus utilizing a blockchain with smart contracts to replace the real addresses of IoT terminals with temporary addresses, ensuring secure communication between IoT terminals and location service providers while maintaining service functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real addresses of IoT terminals are exposed to location service providers, then location-based services can be provided, but user privacy and data security are compromised
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a mediator between IoT terminals and location service providers. The smart contract on the blockchain receives location service requests, replaces real addresses with temporary addresses, and forwards requests to providers. This intermediary mechanism enables location services to function while preventing direct exposure of real terminal addresses, thus resolving the contradiction between service functionality and privacy protection.
2Reliability
If temporary addresses are used to protect privacy, then data security is enhanced, but communication complexity increases
Solution Approach 1:
The smart contract automatically performs address replacement operations without requiring manual intervention. When a location service request arrives, the smart contract autonomously generates temporary addresses, replaces real addresses in the request, and manages the mapping between real and temporary addresses. This self-service automation reduces the perceived complexity for users while maintaining enhanced data security through systematic address management.
Data Source
AI summary
The present disclosure provides a method and an apparatus for processing location-based service data, an electronic device, and a computer readable storage medium. The method includes: receiving a location service request sent by an IoT terminal, the location service request including a real address of the IoT terminal, location information, a type of the location service request, and a location service provider; replacing the real address of the IoT terminal in the location service request with a temporary address using a smart contract, and sending a replaced location service request to the location service provider; receiving a location service response sent by the location service provider; and replacing the temporary address included in the location service response with the real address using the smart contract, and sending a replaced location service response to the IoT terminal.
