Blockchain-based authorization management

Glossary

Term DefinitionsBlockchainA distributed ledger technology used to record transaction data and share it among multiple nodes in a secure, transparent, and tamper-proof manner.Data blockThe basic unit of a blockchain, containing a set of verified transaction data and linked to the previous data block to form an immutable chain.Smart contractA self-executing contract stored on a blockchain, whose terms are defined in code and automatically executed when preset conditions are met.Self-executing tokenA special smart contract that represents the ownership or right to use a tangible or intangible asset and contains self-executing logic for managing and controlling access to and use of that asset.Authorization managementThe process of managing and controlling user access rights to specific resources or services, ensuring that only authorized users can access sensitive information or perform specific actions.Authorization credentialsInformation used to verify user identity and authorize access rights, such as a username, password, access key, or digital certificate.License smart contractA special smart contract that represents a software license agreement and contains self-executing logic for managing the validity, term, terms, and conditions of a license.License factory smart contractA special smart contract used to create and manage multiple license smart contracts and define templates and logic for generating licenses. Usage information Information about how a user uses a particular resource or service, such as usage time, frequency, location, and functional access records. Trigger events Events that trigger the system to perform specific actions or evaluate specific conditions, such as access requests, usage restrictions, or license expiration. Distributed node A node in a blockchain network that maintains a copy of the blockchain and participates in verifying and confirming transactions. Consensus mechanism A mechanism for reaching consensus among distributed nodes to verify and add new data blocks to the blockchain, ensuring data integrity and consistency. Short answer questions

What is a self-executing token and how is it used for authorization management? A self-executing token is a smart contract that represents ownership or usage rights to an asset. In authorization management, a self-executing token can embed licensing terms and automatically grant or restrict access to software or hardware based on preset rules.

What are the advantages of a blockchain-based authorization management system over a traditional system? A blockchain-based authorization management system has the advantages of being decentralized, transparent, secure, and tamper-proof. It eliminates the need for a centralized authorization authority, improves transparency and traceability, and enhances security.

What is the role of a license factory smart contract? The license factory smart contract is used to create and manage multiple license smart contracts. It defines the templates and logic for generating licenses and allows licenses to be automatically created and assigned based on predefined rules.

How is usage information used in a blockchain-based authorization management system? Usage information is recorded on the blockchain and used to track users' usage of authorized resources. Smart contracts can enforce license terms based on usage information, such as limiting usage time or number of accesses.

What is a trigger event and give an example of its role in authorization management? A trigger event is an event that triggers the system to perform a specific action, such as an access request, usage restriction, or license expiration. For example, when a user attempts to access an authorized resource, the system triggers an access request event and verifies the user's access rights based on the license terms.

Explain how blockchain helps maintain the security and integrity of the authorization management system. The decentralized and tamper-proof nature of blockchain enhances the security and integrity of the authorization management system. All transactions are recorded on the blockchain, and any modification requires network consensus, which makes it extremely difficult to tamper with the data.

What role does the company smart contract play in a blockchain-based authorization management system? The company smart contract stores company information and can be linked to the products it provides and the license factory smart contract. It allows company information to be managed and updated and provides a transparent record of the company's authorization activities.

What is the relationship between a product smart contract and a license smart contract? A product smart contract contains information about a specific product and can be linked to one or more license factory smart contracts. A license factory smart contract can use the information defined in a product smart contract to generate license smart contracts that grant access to that product.

Explain how license transfers are implemented in a blockchain-based authorization management system. License transfers can be achieved by updating the ownership information of the license smart contract. The process can be managed by self-executing logic to ensure that only authorized parties can make transfers and that all transfers are recorded on the blockchain.

Describe how a blockchain-based authorization management system facilitates auditing of authorization usage. A blockchain-based authorization management system provides a transparent and immutable record of all authorization activities, including license creation, access requests, and usage information. This makes auditing authorization usage easy and reliable.
