Blockchain-Enabled Reader Identity Attestation for IoT Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices, such as RFID scanners and sensors, lack integration with blockchain networks, leading to issues with data integrity and trust due to missing decentralized identity management, particularly in industrial and logistics applications where machine-to-machine communication protocols like OPC UA lack the ability to manage blockchain identities.
Innovation Solution
A blockchain IoT system is introduced, featuring a publisher node that attests event data from a blockchain-enabled reader using a decentralized identity, which is verified by a subscriber node within the blockchain network, allowing the data to be stored securely in a distributed ledger, thereby maintaining data integrity and trust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing IoT devices communicate using traditional machine-to-machine protocols, then device compatibility and ease of operation are maintained, but data integrity and trustworthiness deteriorate due to lack of decentralized identity management
Solution Approach 1:
The patent merges traditional M2M communication protocols with blockchain technology by integrating decentralized identity management into existing communication frameworks. The system combines OPC UA or MQTT protocols with blockchain-based identity verification, allowing devices to maintain familiar communication methods while gaining enhanced security and data integrity through blockchain-verified identities.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary layer between IoT devices and the central system. This intermediary manages decentralized identities and verifies device authenticity without requiring direct complex cryptographic operations at each device endpoint, thus improving data integrity while managing complexity through the intermediary blockchain infrastructure.
2Reliability
If decentralized identity management is implemented in IoT devices, then data trustworthiness and security are improved, but device complexity and integration difficulty increase
Solution Approach 1:
The patent creates a universal decentralized identity management system that works across multiple IoT devices and communication protocols simultaneously. The blockchain-based identity framework provides a multi-functional solution that can be applied to various device types (sensors, actuators, gateways) and communication standards (OPC UA, MQTT), making the system easier to manufacture and integrate across diverse IoT ecosystems.
Solution Approach 2:
The patent implements preliminary action by pre-provisioning devices with decentralized identities during manufacturing or device initialization. The blockchain identity infrastructure is set up in advance, allowing devices to automatically authenticate and communicate securely from the moment they are deployed, eliminating the need for complex post-deployment identity configuration and reducing integration difficulty.
3Reliability
If blockchain technology is integrated with IoT devices, then data security and integrity are enhanced, but processing time and system complexity increase
Solution Approach 1:
The patent applies partial action by implementing blockchain-based decentralized identity verification only for critical authentication and data integrity checks, rather than requiring full blockchain processing for every IoT communication. This selective approach maintains data security for essential operations while minimizing processing time overhead by avoiding unnecessary blockchain interactions for routine device communications.

AI summary
Examples described herein relate to integrating a blockchain-enabled reader with a blockchain network over machine-to-machine communication protocol. A subscriber node may receive event data published by a publisher node. The event data may be communicated to the publisher node from a blockchain-enabled reader using a machine-to-machine communication protocol. The event data may be attested by the blockchain-enabled reader using a decentralized identity provisioned to the blockchain-enabled reader from the blockchain network. The decentralized identity of the blockchain-enabled reader may be verified. The event data may be submitted by the subscriber node to a distributed ledger upon successful verification of the decentralized identity of the blockchain-enabled reader.
