Method for generating customized views in blockchain

Blockchain customized views:

System overview: The system maintains a blockchain in a distributed network consisting of multiple nodes, each block entry contains multiple data parts, and each part is associated with an access level.

Access control: Receive a user's request to view one or more data parts, evaluate the request according to the user's data access guide, and generate a customized view containing the data parts accessible to the user.

Data access guide:

Guideline definition: The data access guide specifies the framework for user access to one or more data parts in the blockchain, including how data is routed, processed, and stored in the distributed ledger.

Application process: The system receives the data access guide and applies it to the user's access request to determine the data parts that the user is authorized to view.

Customized view generation:

Generation logic: Based on the user's access level and transaction format, the system identifies the accessible data parts in the blockchain and generates a customized view containing these parts.

User interface: The customized view is displayed through the user interface, and the user can only see the data parts that he is authorized to access.

Data classification and encryption:

Data classification: The system is able to identify data categories such as personal information (PII) and set different encryption levels for different categories of data as needed.

Encryption technology: Use non-homomorphic encryption and homomorphic encryption technology to protect data security. Homomorphic encryption allows data to be calculated without decryption.

Regulatory compliance:

Compliance requirements: The system supports various privacy laws and privacy requirements around the world to ensure that data is stored and accessed in a compliant manner.

Audit function: Built-in audit function allows regulators or authorized users to view transaction data in the form of customized views without revealing sensitive information.

Multi-industry application:

Application scenarios: The system can be applied to a variety of industries, including finance, medical care, retail, logistics, etc., providing secure data sharing and auditing functions.

Customized solutions: Provide customized blockchain solutions for different industries to meet specific data access and privacy protection needs.

Technical architecture and components:

System architecture: Including blockchain server, client interface, multi-factor authentication module, report generator and other components, together to realize the customized view function.

Security measures: Multi-level security measures such as encryption/decryption module, analysis module, event module, etc. are adopted to ensure the security and privacy of data.

These points comprehensively summarize the core content of the document, covering key aspects such as system overview, data access guidelines, customized view generation, data classification and encryption, regulatory compliance, multi-industry applications, and technical architecture and components.
