IoT Blockchain Data Security via Segmentation

The patent segments the centralized cloud storage system into multiple distributed nodes forming a blockchain network. Each node stores copies of the data ledger, eliminating the single point of failure. The data is divided into blocks that are chained together cryptographically, with each block containing data from multiple IoT devices. This segmentation maintains data availability for analysis while distributing security risks across the network.

The patent introduces blockchain technology as an intermediary layer between IoT devices and cloud storage. This intermediary provides decentralized data management through smart contracts that automatically execute data storage and retrieval operations. The blockchain acts as a trusted mediator that enables secure peer-to-peer data transmission without requiring centralized cloud servers, thus maintaining analysis capability while improving security.

The patent implements self-service through smart contracts that automatically execute transactions and data operations without human intervention. IoT devices autonomously generate data, the blockchain network automatically validates and stores it in appropriate blocks, and smart contracts trigger executions based on predefined conditions. This self-service mechanism enables autonomous operation while the standardized blockchain protocol simplifies security management compared to custom complex security systems.

The patent applies a universal blockchain protocol that serves multiple functions: data storage, authentication, transaction management, and security validation. This single multi-functional infrastructure replaces multiple separate security protocols and management systems. The blockchain network simultaneously handles identity verification, data integrity checking, and authorized access control, reducing overall system complexity while enabling autonomous operations.

The patent segments data into discrete blocks that are processed and transmitted independently through the blockchain network. Each block contains a subset of IoT data and can be validated and stored separately. This segmentation allows parallel processing of multiple blocks simultaneously, improving overall throughput. The segmented approach maintains security through cryptographic chaining while enabling efficient data transmission by avoiding the need to process entire data sets sequentially.

The patent implements partial validation where not every transaction requires full network consensus before being accepted. The system uses a threshold mechanism where a predetermined number of nodes must validate a block before it is committed to the chain. This partial action approach maintains security by requiring sufficient consensus while avoiding the delays of requiring complete network agreement, thus improving data transmission speed without sacrificing reliability.
