IoT Device Onboarding via Segmented Identity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices operating in multi-framework environments face challenges in discovery and onboarding due to the need for framework-independent unique identifiers, which can compromise privacy and lead to confusion among multiple logical devices representing a single physical device.
Innovation Solution
A method for discovering and onboarding multi-framework IoT devices using a three-identity approach: a non-unique identity for discovery, a secure unique identifier for authenticated sessions, and a physical device identifier for secure directory provisioning, without relying on publicly trackable identifiers, ensuring privacy and disambiguation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If framework-independent unique identifiers are used for device discovery and onboarding, then device identification and tracking capability is improved, but device privacy is compromised and confusion arises among multiple logical devices representing a single physical device
Solution Approach 1:
The patent segments the identification system into three distinct identity types: a non-unique identity for discovery, a secure unique identifier for authenticated sessions, and a physical device identifier for secure directory provisioning. This segmentation allows each identity to serve its specific purpose without exposing trackable information, resolving the contradiction between identification accuracy and privacy protection.
Solution Approach 2:
The patent introduces an intermediary onboarding tool that mediates the onboarding process between the device instance and the secure directory. This intermediary handles the complex identity management and provisioning operations, allowing devices to be identified and onboarded securely without directly exposing unique identifiers in public discovery channels.
2Productivity
If framework-independent unique identifiers are used for device discovery, then device tracking and management capability is improved, but confusion arises among multiple logical devices representing a single physical device
Solution Approach 1:
The patent segments device representation into multiple identity layers: a non-unique identity for public discovery that prevents doppelganger confusion, a secure unique identifier for authenticated management, and a physical device identifier for directory provisioning. This segmentation maintains management efficiency while eliminating confusion about device representations.
Solution Approach 2:
The patent applies local quality by making each identity type context-specific: the non-unique identity is used locally in public discovery channels where trackability is harmful, the secure unique identifier is used locally in authenticated sessions where precision is needed, and the physical device identifier is used locally in secure directory operations. This context-specific application resolves the contradiction between management efficiency and representation clarity.
3Stability of the object's composition
If a single unique identifier is used across all frameworks, then device identification consistency is improved, but adaptability to different framework requirements is reduced
Solution Approach 1:
The patent implements universality by creating a multi-functional identity system where a single device can present different identities appropriate to each framework context. The device instance can use the non-unique identity for discovery in any framework, the secure unique identifier for authenticated sessions in any framework, and the physical device identifier for provisioning in any framework, making the system universally compatible across all frameworks while maintaining consistency.
Solution Approach 2:
The patent applies dynamics by making the device's identity presentation flexible and context-dependent rather than fixed. The device can dynamically select which identity to use based on the framework context and security requirements, allowing consistent device identification across frameworks while adapting to each framework's specific requirements.

AI summary
Various systems and methods for discovery and onboarding in an interconnected network framework of Internet of Things (IoT) devices are described. In an example, a technique for onboarding and provisioning a device onto an interconnected network framework includes operations to: receive a unique temporary device identifier from a device instance, the device instance indicating availability for onboarding onto a network; onboard the device instance onto the network; establish a secure session with the device instance via the network; receive, in the secure session, a secure device identifier; and initiate provisioning of the device instance in a secure directory based on the secure device identifier. In a further example, techniques are provided to securely identify and provision a second device instance (a doppelganger device instance) operating on a physical device that hosts both the first device instance and the second device instance.
