Electronic identity authentication verification method

Identity authentication verification method:

Method overview: The method involves generating and signing authentication records by generating a unique salt value and combining data hash after user data is registered on the blockchain to enhance the security of the authentication process.

Data registration: User data is registered on the blockchain, a registration tx-ID is generated, and the hash value of the data is signed using the user's private key.

Authentication record generation: The hash data combined with the salt value is signed using the private key of the authentication entity to generate an authentication record, and the hashed authentication record is stored on the blockchain.

Blockchain and sidechain storage:

Blockchain storage: The hashed authentication record is first stored on a public or private blockchain to ensure the immutability of the data.

Sidechain storage: The authentication data block is then stored on a sidechain, which can be public or private, further dispersing the storage load and providing additional privacy protection.

Application of salt value:

Salt value generation: Generate a unique salt value and hash it with the data to increase the complexity and unpredictability of the hash value and prevent hash collision attacks.

Authentication record obfuscation: Salt values are used in the authentication record generation process, making it difficult for authentication records to be discovered and cracked by unauthorized third parties.

Authentication verification process:

Data verification: During the verification process, first verify whether the newly submitted data matches the hash value stored on the blockchain to ensure that the data has not been tampered with.

Authentication record verification: Further verify the authenticity and integrity of the authentication record, including verifying the signature and hash value of the authentication record.

Multi-entity authentication and compensation mechanism:

Multi-entity authentication: Multiple authentication entities can authenticate the same data, and each entity generates its own authentication record to enhance the credibility of the data.

Compensation mechanism: Through methods such as initial coin offerings (ICOs), the distribution of salt values is controlled, so that downstream authentication entities need to pay compensation to obtain salt values, thereby sharing the cost of the first authentication.

Application scenarios:

Commercial applications: Identity authentication methods can be used in multiple business fields such as banking, travel, and communications to ensure the security of user identity verification.

Privacy protection: Allow users to selectively share authentication data to protect user privacy from being leaked.

System architecture:

System components: The system includes user devices, authentication devices, verification devices, blockchain networks and other components, and realizes data registration, authentication and verification through network connection.

Device functions: User devices are used to generate and submit user data, authentication devices generate authentication records, and verification devices verify the authenticity and integrity of data.

What is the "salt value" in the electronic identity authentication verification method, and what role does it play in the authentication process?

Answer key: The salt value is a unique value, usually a random number or GUID. During the authentication process, the salt value is combined with the user data for hashing to increase the complexity and unpredictability of the hash value, prevent hash collision attacks, and thus improve the security of the authentication record.

Briefly describe the process of user data registration and authentication record generation on the blockchain.

Answer key: User data is first registered through the blockchain, a registration tx-ID is generated, and the hash value of the data is signed with the user's private key. Then, the authentication entity generates a unique salt value, hashes the salt value with the user data, and signs the hashed data with the private key of the authentication entity to generate an authentication record. The authentication record and its hash value are then stored on the blockchain.

What roles do blockchain and sidechain play in the electronic identity authentication method?

Answer key: Blockchain is used to store hashed authentication records to ensure that the data cannot be tampered with. As a supplement to blockchain, sidechain is used to store authentication data blocks, further dispersing the storage load and providing additional privacy protection. Sidechains can be public or private, depending on specific needs.

How does the multi-entity authentication mechanism work and how does it enhance the credibility of data?

Answer key: The multi-entity authentication mechanism allows multiple authentication entities to authenticate the same data, and each entity generates its own authentication record. These authentication records together constitute multiple verifications of the data, thereby enhancing the credibility of the data. Even if one authentication entity has a problem, other authentication records can still serve as valid proof.

In the electronic identity authentication method, how to share the cost of the first authentication through a compensation mechanism?

Answer key: Control the distribution of salt values through methods such as initial coin offerings (ICOs). Downstream authentication entities need to pay compensation to obtain the salt values generated by the first authentication entity so that they can generate their own authentication records. This method allows the cost of the first authentication to be shared among multiple authentication entities.

What are the potential advantages of electronic identity authentication methods in commercial applications?

Answer key: In commercial applications, electronic identity authentication methods can provide an efficient and secure identity authentication mechanism, which is suitable for multiple fields such as banking, travel, and communications. It can ensure the authenticity and integrity of user identities while protecting user privacy from being leaked. In addition, multi-entity authentication mechanisms and flexible storage solutions also provide more flexibility and security for commercial applications.
