Short answer

The user terminal (100) can be any smart device that can provide services and perform communications, such as a personal computer, tablet, smartphone, car navigation, etc. These devices need to have communication functions and the ability to process information.

The first service (210) and the second service (220) are both platforms that provide services to users, and the difference is that the service content they provide is different. For example, the first service can be a social media platform, and the second service can be an e-commerce platform.

The role of the first server (310) and the second server (320) is to perform blockchain integration, connect to the first blockchain (410) and the second blockchain (420) respectively, and handle operations such as user authentication, data writing and reading.

PKI (Public Key Infrastructure) is a system for generating and managing key pairs. In the system, it is used to generate a user's public and private key pair and sign user information with a private key to ensure the authenticity of the user's identity.

The user's biometric information can be used to generate a private key or as an auxiliary verification method. For example, the user can use fingerprint or iris information for identity authentication to enhance the security of the system.

The verification value is a value used to verify the user's identity. The system uses verification values ​​such as random numbers (nonce), one-time passwords (OTP) and timestamps to ensure the real-time and tamper-proof nature of user identity authentication requests.

The Merkle tree is used to efficiently verify the integrity of data. The system uses the Merkle tree to record the user's transaction information and stores the root hash value of the Merkle tree on the blockchain to quickly verify the integrity of the user's data.

The trigger condition is the condition that triggers a specific operation. The system uses trigger conditions such as the number of transactions, time intervals, and block generation to determine when to write user information to the blockchain.

The URL scheme is used to transfer information between applications. For example, when a user completes identity authentication on the first application (110), the verification result can be passed to the second application (120) through the URL scheme.

When the second user is not registered on the second blockchain (420), the second server (320) returns the query result to the first server (310), and the first server (310) can choose to reject the user's login request or guide the user to register on the second service.
