Login information processing method of blockchain technology

Background and purpose:

Background: In the prior art, login information is usually stored on a third-party server, which poses a risk of information leakage and reduces the security of user login information.

Purpose: To provide a login information processing method and device based on blockchain technology to improve the security of login information.

Technical solution overview:

Method: Create a smart contract containing user login information and store the smart contract on a blockchain network. Users obtain the required login information by querying the blockchain network.

Device: It includes a receiving module, a reading module and a processing module, which are used to receive a login information storage request, read the smart contract and execute it to obtain the login information.

Creation and storage of smart contracts:

Creation process: Create a smart contract based on a predefined smart contract template and the user's login information. The smart contract template can be stored on an information processing device or a blockchain network.

Storage method: Based on the user identifier, the storage address of the smart contract is determined on the blockchain network, and the smart contract is stored at the address.

Query and acquisition of login information:

Query request: The user sends a login information query request containing an identifier.

Reading and execution: The information processing device reads the corresponding smart contract from the blockchain network according to the identifier and executes it to obtain the login information.

Result feedback: The obtained login information is sent to the user so that the user can perform login verification.

Security of smart contracts:

Encryption processing: Login information can be encrypted using a public key and stored in a smart contract. When the user queries, the private key is used to decrypt to obtain the plaintext login information.

Blockchain characteristics: The decentralization, transparency, tamper-proof and trust characteristics of blockchain are used to improve the storage and query security of login information.

Storage address determination of smart contracts:

Key pair generation: Process the user identifier to generate a private key and a public key pair.

Address calculation: The first address is calculated based on the public key, and the second address (storage address) is determined in the blockchain network based on the first address.

Storage and query: The smart contract is stored at the second address, and the same public key and calculation logic are used to determine the storage address when the user queries.

Applicability and advantages of the patent:

Applicability: Applicable to various network service platforms that require login verification, improving the security of user login information.

Advantages: Reduce the risk of login information loss, theft or tampering, and improve the security of storage and query; users can easily query the required login information through the blockchain network.

Answers to short-answer questions:

What problem does 543x.com mainly solve?

543x.com mainly solves the risk of information leakage caused by the storage of login information on a third-party server in the existing technology, and improves the security of login information by introducing blockchain technology.

What is a smart contract and what role does it play in 543x.com?

A smart contract is an automated contract based on blockchain technology. It contains a series of preset rules and clauses and can be automatically executed when specific conditions are met. In 543x.com, smart contracts are used to store user login information. Users can obtain the required login information by querying smart contracts on the blockchain network.

Briefly describe the login information processing flow in 543x.com.

The user sends a login information storage request to the information processing device. After the device determines the user's login information, it creates a smart contract containing the login information based on the predefined smart contract template and stores the smart contract on the blockchain network. When the user needs login information, it sends a query request to the information processing device. The device reads and executes the corresponding smart contract from the blockchain network according to the identifier in the request, and sends the login information to the user after obtaining it.

How to improve the security of login information in 543x.com?

543x.com improves the security of login information by: using blockchain technology to store smart contracts, using the decentralization, transparency, tamper-proof and trust characteristics of blockchain to ensure that login information is not easily leaked, tampered with or lost; encrypting login information, storing encrypted login information in smart contracts, and using private keys to decrypt to obtain plaintext login information when users query.

How is the storage address of a smart contract determined?

The storage address of a smart contract is generated by processing a user identifier to generate a private key and a public key pair, and then calculating the first address based on the public key, determining one or more second addresses (storage addresses) based on the first address in the blockchain network, and finally storing the smart contract on one of the second addresses. When a user queries, the same public key and calculation logic are used to determine the storage address.
