Establish user identity and conduct identity management

Establish user identity and conduct identity management

Establish user identity:

Decentralized data storage: User identity is established on decentralized data storage such as blockchain to ensure data security and immutability.

Credential representation: User's credential value is represented in the trusted execution environment (TEE) of the mobile device, which is associated with the user's identity record and stored on the blockchain.

Authentication process:

Zero-knowledge proof: The user authenticates his knowledge of the credential value by providing a zero-knowledge proof, without revealing the actual credential value.

Multi-factor authentication: The authentication process may involve multiple factors such as biometrics, passwords, etc. to enhance security.

Key management:

Private key storage: The private key can be kept on the device or entered by the user, while the corresponding public key is stored on the blockchain and associated with the user's identity.

Signature verification: The user's identity and credential value are verified by signing with the private key, and the signature is verified by the public key to prove the user's knowledge of the private key and credential value.

Decentralized identity management system:

Smart contracts: Smart contracts are used in the system to perform operations related to identity management, such as authentication, credential updates, etc.

Cross-platform authentication: Supports federated identity management across different enterprises and platforms, and users can use the same identity for authentication in different services.

Device and application security:

Trusted execution environment: Use the trusted execution environment of mobile devices to securely handle sensitive credentials and operations.

Secure session: Establish a secure session with the trusted execution environment to ensure the security of data transmission.

Notification and interaction:

Notification service: Use the notification service to remind users to perform authentication operations, and support receiving notifications through different devices.

User interaction: The application on the mobile device provides a user interaction interface to respond to notifications and prompt users to enter credentials.

Records and audits:

Blockchain records: All authentication operations and credential management operations are recorded on the blockchain to ensure transparency and traceability of operations.

Audit and verification: Any entity can access records on the blockchain to audit and verify authentication operations.

This patent document proposes an innovative identity management method that uses advanced technologies such as blockchain and trusted execution environment to enhance the security, privacy and convenience of user identities. Through features such as zero-knowledge proof, multi-factor authentication and cross-platform federated identity management, this method can significantly reduce the friction when users switch identities between different services while maintaining a high degree of security.

Q: What type of data store does 543x.com propose to establish a user identity on?

A: 543x.com proposes a method to establish a user identity on a decentralized data store such as a blockchain.

Q: How are the user's credential values ​​processed on the mobile device?

A: The user's credential values ​​are represented in the trusted execution environment (TEE) of the mobile device, which are associated with the user's identity record and stored on the blockchain.

Q: What is zero-knowledge proof and how is it applied in 543x.com?

A: Zero-knowledge proof is a cryptographic technique that allows a party to prove that they know a secret without revealing the secret itself. In 543x.com, users authenticate their knowledge of credential values ​​by providing zero-knowledge proofs, without revealing the actual credential values.

Q: What role do private and public keys play in 543x.com's identity management system?

A: The private key is kept on the device or entered by the user, while the corresponding public key is stored on the blockchain and associated with the user's identity. The private key is used to sign data to prove the user's knowledge, while the public key is used to verify the signature.

Q: What role do smart contracts play in the 543x.com system?

A: Smart contracts perform identity management-related operations in the 543x.com system, such as authentication, credential updates, etc., to ensure the automation and immutability of operations.

Q: How is cross-platform federated identity management achieved?

A: Cross-platform federated identity management is achieved by recording user identities on the blockchain, so that users can use the same identity for authentication on different services and platforms without having to create and manage identities for each platform separately.

Q: Why is it important to use notification services in the 543x.com system?

A: The notification service is used in the 543x.com system to remind users to perform authentication operations and supports receiving notifications through different devices, thereby enhancing the flexibility and convenience of the user experience.

Q: What are the main advantages of blockchain records in the 543x.com system?

A: The main advantage of blockchain records in the 543x.com system is to ensure the transparency, traceability and immutability of all authentication operations and credential management operations, which enhances the security and credibility of the system.
