Embodiment Construction

[0048] In order to describe the content and object of the present invention more concisely and clearly, the present invention will be further described below in conjunction with the accompanying drawings. The specific steps to implement the case are as follows:

[0049] Step 001: The user registers an account, such as Figure 6 shown.

[0050] Step 002: The data owner publishes the data, such as Figure 8 shown.

[0051] Step 003: The user views the published data, such as Figure 9 shown.

[0052] Step 004: Data consumers publish data request tasks, and set task-related attribute information, such as Figure 10 shown.

[0053] Step 005: The data owner receives the data request task, and adds the task publisher to his data request list

[0054] Step 006: The data owner authorizes and submits the task for the data consumer.

[0055] Step 007: The user checks the change history of reputation points.

[0056] Step 008: The user checks the usage history of the personal da...

Abstract

The invention discloses an Internet of Things credible data service model based on a block chain. An application layer provides system visual interaction entrances for different terminals; The servicelayer adopts an eggjs framework based on nodejs upwards to provide a service interface for the application layer, and adopts web3js downwards to interact with the intelligent contract layer to realize a service providing function interface; The intelligent contract layer uses a Solidity language to realize the core function of the perception service and related business logic; The block chain layer builds a private chain based on an Etherum platform to realize a distributed block chain network environment, and utilizes a consensus mechanism, an encryption algorithm, a timestamp and other technologies to help to realize data security storage and data traceability; And the storage layer stores metadata in a manner of combining a traditional database and an IPFS distributed file system. A more effective solution is provided for data service management of the Internet of Things, and meanwhile, a convenient data interaction means is provided for related data analysis departments.

Description

technical field [0001] The present invention relates to technical fields such as Internet of Things services, block chain technology, encryption algorithm technology, and distributed data storage, and in particular to block chain technology to realize a distributed trusted data service model of the Internet of Things based on block chains. Background technique [0002] The Internet of Things is a new model of urban development in the world today, and smart city applications based on Internet of Things technology are used to process and analyze urban big data collected from devices, citizens, and assets to revolutionize many aspects of urban management, such as the environment, Transportation systems, sanitation, water supply networks, etc. The Internet of Things (IoT) is the foundation - the spiritual infrastructure that enables big data collection in cities. Generally speaking, IoT solutions for urban data collection can be divided into dedicated sensor platforms (i.e., wi...
