Distributed Ledger Profile Sharing Across Private Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of IoT devices connected to local wireless networks leads to complex access control and profile management, making it difficult for users to port their personal settings and preferences seamlessly across different environments, such as when traveling.
Innovation Solution
A method utilizing a combination of private and public distributed ledgers, where profile information is stored and shared securely, allowing nodes to authenticate and request profile data across networks, enabling secure and automatic access control and delivery of user profiles without relying on centralized trust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If profile information is manually configured for each device, then device-specific customization is achieved, but user mobility and ease of operation deteriorate
Solution Approach 1:
The patent creates a digital copy of user profile information stored on a user's device, which can be automatically transferred to new devices or networks. This copy contains all personalized settings and preferences, eliminating manual reconfiguration when users move between networks or devices.
Solution Approach 2:
The system performs preliminary actions by pre-configuring profile information on the user's device before network transitions occur. When a user joins a new network, the profile data is automatically made available without requiring manual setup, as the configuration work was already done in advance.
2Reliability
If distributed ledgers are used for profile sharing, then security and reliability are improved, but device complexity and information loss increase
Solution Approach 1:
The patent introduces a distributed ledger as an intermediary layer between users and networks. This mediator securely stores and manages profile information, allowing automatic verification and sharing without requiring complex trust relationships between individual devices and networks.
Solution Approach 2:
The distributed ledger serves multiple functions simultaneously: it acts as a secure storage repository, an authentication mechanism, a data sharing platform, and a trust verification system. This multi-functionality reduces the need for separate complex systems for each purpose.
3Adaptability or versatility
If profile information is stored locally on devices, then access speed is improved, but adaptability and information loss worsen
Solution Approach 1:
The patent merges local profile storage with distributed ledger technology. Profile information is stored locally on user devices for quick access, while simultaneous copies are maintained on the distributed ledger network, ensuring information availability and portability without loss during transmission between devices or networks.

AI summary
According to an example aspect, there is provided a method for obtaining profile information by a node of a distributed network. Need for providing profile information for a user by a node of a second local private network is detected. A profile request transaction is provided to a public distributed ledger for obtaining profile information associated with the user. Profile information associated with the user is received from a providing node capable of accessing a first private distributed ledger storing the profile information. At least some of the received user profile information is provided for at least one device connected to the second local private network.
