As the development of IoT technologies has progressed rapidly recently, most IoT data are focused on monitoring and control to process IoT data, but the cost of collecting and linking various IoT data increases, requiring the ability to proactively integrate and analyze collected IoT data so that cloud servers (data centers) can process smartly. In this paper, we propose a blockchain-based IoT big data integrity verification technique to ensure the safety of the Third Party Auditor (TPA), which has a role in auditing the integrity of AIoT data. The proposed technique aims to minimize IoT information loss by multiple blockchain groupings of information and signature keys from IoT devices. The proposed technique allows IoT information to be effectively guaranteed the integrity of AIoT data by linking hash values designated as arbitrary, constant-size blocks with previous blocks in hierarchical chains. The proposed technique performs synchronization using location information between the central server and IoT devices to manage the cost of the integrity of IoT information at low cost. In order to easily control a large number of locations of IoT devices, we perform cross-distributed and blockchain linkage processing under constant rules to improve the load and throughput generated by IoT devices.
随着物联网技术近年来的快速发展，大多数物联网数据都集中在监测和控制以处理物联网数据，但收集和链接各种物联网数据的成本增加，需要具备主动整合和分析收集到的物联网数据的能力，以便云服务器（数据中心）能够智能处理。在本文中，我们提出了一种基于区块链的物联网大数据完整性验证技术，以确保在审核人工智能物联网数据完整性方面发挥作用的第三方审计机构（TPA）的安全。所提出的技术旨在通过对物联网设备的信息和签名密钥进行多个区块链分组来最小化物联网信息丢失。所提出的技术通过将指定为任意固定大小块的哈希值与分层链中的先前块链接起来，有效地保证了物联网信息对人工智能物联网数据的完整性。所提出的技术利用中央服务器和物联网设备之间的位置信息进行同步，以低成本管理物联网信息完整性的成本。为了轻松控制大量物联网设备的位置，我们在恒定规则下进行交叉分布式和区块链链接处理，以改善物联网设备产生的负载和吞吐量。
