Embodiment Construction

[0057] 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:

[0058] Step 001: The user registers an account, such as Figure 5 shown.

[0059] Step 002: Data provider registration data, such as Figure 6 shown. At this time, the system will record the newly registered traceability records and store them on the chain.

[0060] Step 003: The user views the published data list, such as Figure 14 shown. Data consumers select data according to their own needs and make data requests, and then wait for the data provider to review the request.

[0061] Step 004: After the data provider reviews the data request, it authorizes data access. At this time, the system records and stores the data entity circulation information and traceability records. Data consumers evaluate the data...

Abstract

The invention discloses an Internet of Things data tracing method based on a block chain, and the method comprises the steps: dividing roles of users in an Internet of Things data service system in tracing data collection, so as to facilitate the collection of tracing data through a PROV tracing model standard. A seller and a processor can carry out secondary processing on data obtained from a provider, operation information carried out for a data entity needs to be submitted when the data is published, and whether the data operation information is submitted or not is listed as an important component of data evaluation; in the traceability data storage, a data entity ID number is taken as a key, a traceability record is value, and different key value pairs are subjected to uplink storage through an intelligent contract; and the traceability data query queries the traceability record of the data through the unique ID number of the data entity. According to the method, the capability ofchecking the data transfer process before the data is used is provided for the user, and due to the characteristics of decentralization, tamper resistance, trusted storage and the like of the block chain, the standard automatic execution of the Internet of Things data traceability service entity is realized.

Description

technical field [0001] The present invention relates to technical fields such as Internet of Things data services, block chain technology, data traceability technology, and encryption algorithm technology, and especially relates to block chain technology and data traceability technology. The present invention aims to realize a block chain-based Internet of Things data traceability method. Background technique [0002] Data has become the most important strategic resource since humans entered the era of big data. With the continuous development of IoT technology, the amount of IoT data collected by sensors has exploded. Through deep mining and analysis of IoT data, it can continue to facilitate human life in various ways. While IoT data brings positive impact, it also brings some problems: this kind of data is integrated and shared among various enterprises and departments through different circulation channels, or a series of data processing is performed, and the middle pr...
