Wireless Device User-Service Association for Ad Hoc Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack a secure and efficient method to differentiate between known and unknown users for service exchange in ad hoc networks, posing safety concerns when receiving services from nearby devices.
Innovation Solution
A wireless communication apparatus that associates service information with user information and transmits this data, allowing the control unit to judge whether to receive services based on user information matching an allow list or blocked list, ensuring safe service exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication apparatuses autonomously interconnect in an ad hoc network, then communication freedom and ease of operation are improved, but safety and reliability deteriorate due to inability to distinguish between known and unknown users
Solution Approach 1:
The patent applies preliminary action by pre-registering user information (device identifiers, user profiles) in a database before wireless communication occurs. When a service request is made, the system proactively checks the requester's identity against the pre-stored user information to determine whether to grant service access, thereby preventing unauthorized access before it can occur.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a user information database that mediates between wireless communication apparatuses. This database stores and verifies user identities, acting as a trusted intermediary that enables safe service exchange without requiring direct trust relationships between all communicating devices in the ad hoc network.
2Productivity
If service information is transmitted without user identification, then communication efficiency is improved, but security and access control worsen
Solution Approach 1:
The patent merges service information transmission with user identification data by incorporating device identifiers and user profile information into the same communication packets. This combination allows the system to simultaneously achieve efficient service discovery and robust access control, as the receiver can verify the sender's identity while processing the service request in a single integrated operation.
