Blockchain Wireless Access Point Information Sharing

The patent segments the centralized backend server into multiple distributed blockchain nodes. Each node stores a copy of the access information in the blockchain ledger, transforming a single point of failure into a distributed network where service continuity is maintained even if individual nodes fail. This segmentation resolves the contradiction by distributing data storage across multiple independent entities while maintaining operational simplicity through standardized protocols.

The patent introduces smart contracts as intermediaries that automatically manage access information sharing and verification between terminal devices and blockchain nodes. The smart contract acts as a mediator that enforces access control policies, handles verification processes, and coordinates resource transfers without requiring complex centralized management. This intermediary layer maintains ease of operation while enabling reliable distributed storage and retrieval.

The patent implements preliminary verification through smart contracts that validate terminal device credentials and access requests before allowing access information to be retrieved from the blockchain. The verification process checks user authentication, device legitimacy, and access permissions in advance, preventing unauthorized access. This preliminary action ensures that while access information is widely synchronized across blockchain nodes for reliability, security risks are mitigated through pre-validated access control.

The patent applies local quality by allowing different blockchain nodes to have different levels of access information storage and verification capabilities based on their roles and security requirements. Not all nodes store or process all types of access information equally - instead, nodes are configured with appropriate permissions and verification levels suited to their specific functions. This differentiation maintains security while enabling widespread distribution of critical access information for service continuity.

The patent performs verification in advance through smart contracts that authenticate terminal devices and validate access permissions before the actual access request is processed. By conducting verification preliminarily - checking credentials, validating device identity, and confirming access rights before allowing blockchain access - the system ensures security without adding time delays during the critical access moment. The preliminary verification results are cached and used to expedite subsequent access operations.

The patent implements self-service verification where terminal devices autonomously present their credentials and the smart contract automatically validates them against stored verification data in the blockchain. The verification process is automated and self-executing, eliminating the need for manual security checks or time-consuming human intervention. This self-service approach maintains high security standards while minimizing processing time through automated credential validation and rapid authentication decisions.
