Blockchain IoT Profile Transfer for Smart Device Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart devices in living or working spaces often require manual reconfiguration by new users after a change in occupancy, which is time-consuming and inefficient.
Innovation Solution
A method utilizing a blockchain-based system to create, modify, and transfer ownership of network blocks containing device metadata, allowing seamless transfer of device control from one user to another without manual reconfiguration.

Engineering Contradiction Analysis
1Reliability
If manual reconfiguration of each smart device is performed by new users, then device control can be transferred, but time and effort are significantly consumed
Solution Approach 1:
The system performs preliminary actions by pre-configuring device metadata and control permissions in a blockchain ledger before user transfer occurs. When a user moves out, their device preferences and control settings are already stored and linked to their profile. The new user simply needs to claim the profile, and the system automatically transfers all device control permissions and configurations, eliminating the need for manual reconfiguration of each device.
Solution Approach 2:
The system creates a digital copy of the previous user's device control profile and preferences in the blockchain ledger. This profile copy contains all necessary metadata, permissions, and settings. When transfer is initiated, this copied profile is linked to the new user's account, effectively replicating the previous user's device control experience without requiring them to manually reconfigure anything.
2Ease of operation
If each smart device is individually configured with user settings, then precise device control is achieved, but system complexity increases
Solution Approach 1:
The system merges individual device configurations and user settings into a unified user profile stored in the blockchain ledger. Instead of managing separate configurations for each smart device, all device metadata, permissions, and preferences are consolidated into a single transferable profile. This unified approach simplifies the system architecture while maintaining precise device control capabilities.
Solution Approach 2:
The blockchain-based profile system serves multiple functions simultaneously: it stores device metadata, manages user permissions, preserves device preferences, and enables seamless transfer of control. This universal profile structure replaces multiple separate configuration systems, reducing overall system complexity while maintaining comprehensive device control functionality.

AI summary
A method may create a network block related to one or more devices located within the physical space. The method may write the network block to a ledger under a first user profile. The method may receive a request to transfer ownership of the network block. The method may link the network block to a second user profile in response to receiving the request.
