Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing device usage information, particularly in the industrial sector, rely on central authorities for manipulation protection, which is inefficient and lacks decentralized security mechanisms.
Innovation Solution
A method utilizing a blockchain data structure based on cryptocurrency, where transaction data related to device usage is generated and stored in a decentralized network, ensuring protection against manipulation through a distributed database with multiple trusted nodes performing mining and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized trusted authority is used to store and protect device usage information, then manipulation protection is provided, but the system complexity and dependency on central authorities increase
Solution Approach 1:
The patent segments the centralized trust model into a decentralized network of blockchain nodes. Instead of relying on a single trusted authority, the system distributes trust across multiple independent nodes that collectively secure the device usage information through cryptographic verification and consensus mechanisms.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between device usage information and trusted storage. The blockchain acts as a decentralized mediator that provides manipulation protection without requiring traditional central authorities, using cryptographic hashing and distributed consensus to ensure data integrity.
2Ease of manufacture
If device usage information is stored in centralized databases or controllers, then storage is simplified, but security against manipulation is compromised
Solution Approach 1:
The patent creates redundant copies of device usage information across multiple blockchain nodes in the decentralized network. Each node stores and verifies copies of the data, ensuring that no single point of failure exists and that manipulation attempts are detected through cryptographic verification at each node.
3Reliability
If traditional key infrastructure and certificates are used for securing device usage information, then trust is established, but the cost and complexity of implementation increase
Solution Approach 1:
The patent replaces the mechanical and administrative systems of traditional key infrastructure and certificate authorities with a cryptographic-based blockchain system. Trust is established through mathematical cryptography and distributed consensus rather than through hierarchical certificate validation, simplifying the implementation while maintaining or enhancing security.

AI summary
Provided is a method for securing an item of device use information of a device, having the following steps: —determining the item of device use information; —generating transaction data depending on the item of device use information; —generating a blockchain data structure which is based on a cryptocurrency and includes the transaction data or a checksum of the transaction data; —sending the generated blockchain data structure to at least one blockchain node. The item of device use information of a device according to the described method is change-protected by a decentralized security structure. Thanks to the distributed blockchain database, the item of device use information of the device cannot be manipulated subsequently. The use of the decentralized blockchain technology also advantageously means that no central trusted point or party is necessary.
