Programmable blockchain

User authentication method:

Based on blockchain technology, user ID and public key are registered in the blockchain.

Verify the signature and original text to ensure the authenticity and integrity of the user's identity.

System composition:

Includes user terminal, service provider server and programmable blockchain.

Connect the user terminal, service provider server and blockchain through the network.

Technical features:

Using programmable blockchain, you can load and execute a variety of programs.

Use programmable blockchain platforms such as Ethereum to ensure the security of user information and the integrity of the authentication program.

User registration stage:

Users encrypt personal information with public keys to generate ciphertext.

Users submit ciphertext to the blockchain for registration.

User authentication stage:

The service provider server sends an authentication request to the user terminal.

The user terminal signs the authentication request with a private key and sends the signature to the service provider server.

The service provider server verifies the signature and original text to confirm the user's identity.

Information transmission security:

Ensure the transmission security of user information through blockchain to prevent hacker attacks.

Even if the blockchain is attacked, user information is still safe because the private key is only held by the user.

User information changes:

Users can encrypt new information with public keys and update it to the blockchain.

The service provider server can verify whether the specific information provided by the user is true.

A user authentication method and system based on blockchain technology, by registering user ID and public key to the blockchain, realizes the authenticity and integrity verification of user identity, while ensuring the security of user information transmission, and improves the security and efficiency of user authentication.

Short answer question:
