User identity and permissions of blockchain

User identity and permissions of blockchain

It mainly introduces the innovative solution of verifying user identity and permissions through blockchain technology. The following is a summary of the key points of the document:

System Overview:

System composition: including components such as server, blockchain network, program memory, etc. The server communicates with the blockchain network and executes program instructions to verify user identity and permissions.

Verification process: receiving blockchain ID, aggregating blockchain transactions, establishing trust relationship, and generating trust profile.

Blockchain ID and transaction:

Blockchain ID: A blockchain identifier associated with a user, usually an encrypted public key.

Blockchain transaction: includes various transactions performed by users on the blockchain, which are used to verify the identity and behavior of the user.

Trust relationship and trust profile:

Trust relationship: established based on blockchain transactions between users and second entities (such as insurance companies, banks, etc.).

Trust profile: contains the trust level between the user and the second entity, and is generated based on the number and quality evaluation of blockchain transactions.

Verification method and implementation:

Method overview: Determine the user's trust level by receiving blockchain ID, aggregating transaction data, and analyzing verification events in transactions (such as marriage, divorce, house purchase, etc.).

Implementation: This paper specifically describes how to perform the verification process in a blockchain network, including communication between nodes, grouping and storage of transactions, and generation of trust profiles.

Security and privacy:

Security: The decentralized, open, and encrypted nature of blockchain enhances the security of the system, making it difficult for hackers to attack.

Privacy protection: Users can choose which private transactions can be accessed to protect their privacy.

Application scenarios:

Financial services: such as bank transaction verification and insurance claim processing.

Identity authentication: Verify user identity through blockchain records, which is applicable to a variety of scenarios requiring identity authentication.

Other fields: This system can be applied to any field that requires high security and identity authentication.

Advantages and features:

Enhance trust: Enhance trust between users and entities through the immutability of blockchain.

Improve efficiency: Automated verification processes reduce the need for manual review and improve processing efficiency.

Reduce risks: Reduce the risk of identity fraud and abuse of authority.

This document describes in detail a user identity and authority verification system based on blockchain, demonstrating the great potential of blockchain technology in improving data security and enhancing trust relationships, and provides innovative solutions for multiple fields such as financial services and identity authentication.
