Sensitive data trading system and method based on block chain

Abstract

The invention relates to a sensitive data trading system based on a block chain, which comprises a block chain bottom layer module, an electronic contract layer module and a SaaS layer module. The block chain layer module provides technical support for bottom block chain, includes a virtual machine supporting electronic contract running, a consensus algorithm, a transaction verification mechanismand an accounting mechanism; The electronic contract layer module provides distributed application services, endorses by using block chain technology, and runs the code of system sensitive data transaction and the code of digital generation algorithm in electronic contract layer. The SaaS layer module provides cloud platform services, so that the participants through the web platform, client, areconvenient to participate in business cooperation. The invention provides the data trading system based on the block chain, which is used for multiple parties to participate in the joint production ofsensitive data, the final sensitive data is obtained by the final data generator, and other roles do not know the final data in the data production process, so that the leakage of the sensitive datain the circulation process is prevented.

Description

technical field [0001] The present invention relates to the fields of block chain technology and e-commerce technology, in particular, to a sensitive data transaction system and method based on block chain. Background technique [0002] Anti-counterfeiting traceability has always been one of the necessary production elements for traditional enterprises. All products produced by regular enterprises have an anti-counterfeiting label with a QR code or a one-dimensional code for anti-counterfeiting traceability query. The content of the label is essentially a string of numbers. Code (referred to as: digital). [0003] In the current industry, the digital is usually generated by the system integrator, and then delivered to the printing factory. The printing factory uses the digital to make paper or plastic anti-counterfeiting labels, and then gives it to the industrial customers (manufacturing companies). The industrial customers label in the production process and use the system...

AI Technical Summary

Problems solved by technology

[0006] 1. In the process of digital circulation, there is a risk of artificial leakage of digital information;

[0007] 2. In the event of a digital leak, all parties involved cannot prove their innocence, and usually share the responsibility and make compensation together;

[0008] 3. System integrators and printing factories cannot store evidence well and identify the authenticity of upstream agents

[0009] 4. After the digital data is produced, it is stored in the database of each system integrator for future reference, and may be tampered with by the staff
