Method and System for Identifying and Tracking IoT Device based on Multi-dimensional Block Chain

摘要

Disclosed is a method and system for identification and transaction transaction tracking of IoT devices based on multiple blockchains. Device information block chain that linearly connects device information blocks containing IoT device identification information in a row direction (transverse direction), and transaction information blocks containing transaction information related to the transaction behavior of each IoT device. It uses multiple blockchains that include a transaction information blockchain that is linearly connected to the block in the column direction (longitudinal direction). The device information blockchain is placed on the top row of multiple blockchains. This type of arrangement of device information blocks is a very efficient arrangement for finding a device information block corresponding to an IoT device since only the top row desired is searched. Any IoT device's transaction processing can be done very efficiently. When the device information block of the desired IoT device is found, it is only necessary to find the last transaction information block targeting only the transaction information block connected to the block and connect a new transaction information block below the block. It is not necessary to search the entire transaction information of all IoT devices.
