Problems solved by technology

[0005] 1. In the process of digital circulation, there is a risk of artificial leakage of digital information;
[0006] 2. In the event of a digital leak, all parties involved cannot prove their innocence, and usually share the responsibility and make compensation together;
[0007] 3. System integrators and printing factories cannot store evidence well and identify the authenticity of upstream agents
[0008] 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

Embodiment 1

[0079] Embodiment 1: a blockchain-based sensitive data transaction system, including a blockchain layer module, an electronic contract layer module, and a SaaS layer module;

[0080] The blockchain layer module provides the technical support of the underlying blockchain, including a virtual machine that supports the operation of electronic contracts, a consensus algorithm, a transaction verification mechanism and an accounting mechanism;

[0081] The electronic contract layer module provides distributed application services, endorsed by blockchain technology, and at the electronic contract layer, runs the code of the system sensitive data transaction and the code of the digital generation algorithm;

[0082] The SaaS layer module provides cloud platform services, allowing all participants to easily participate in business collaboration through the web platform and the client.

[0083] Preferably, each of the blockchain layer module, electronic contract layer module and SaaS la...

Embodiment 2

[0101] Embodiment 2: The present invention also proposes a method for a blockchain-based sensitive data transaction system, including the following steps:

[0102] In the first step, the first participant obtains a random number A_1 through the hash algorithm according to the order information, which is stored in the electronic contract and is invisible to the outside world;

[0103] In the second step, the second participant obtains a random number A_2 through the Hash algorithm according to the order information, and stores it in the electronic contract for the subsequent generation of the code, which is invisible to the outside world;

[0104] The third step is the step of uploading the seed code by the third party. If the third party has the seed code, he / she can choose to upload the seed code to the blockchain electronic contract, and the seed code is generated by the third party; If the third party does not have the seed code, the seed code will actually be automatically...

Embodiment 3

[0106] Embodiment 3: The present invention also proposes a method for applying a blockchain-based sensitive data transaction system, including the following steps:

[0107] S1, the steps for industry customers to place anti-counterfeiting label orders to agents or directly to system integrators and printing factories;

[0108] Industry customers log in to the industry user sub-module, place anti-counterfeiting label orders to agents, and call the electronic contract interface through the SaaS layer. The hash algorithm obtains a random number A_1, which is stored in the electronic contract and is invisible to the outside world;

[0109] S2, the steps that the agent obtains the anti-counterfeiting label order from the industry customer and outsources it to the system integrator and the printing factory;

[0110] The agent logs into the agent user sub-module, and the anti-counterfeiting label order is transferred to the agent's account at this time. The agent confirms the anti-c...

Abstract

A sensitive data transaction system based on the blockchain, including the underlying module of the blockchain, the electronic contract layer module and the SaaS layer module; the blockchain layer module provides technical support for the underlying blockchain, including a virtual machine that supports the operation of the electronic contract , consensus algorithm, transaction verification mechanism and accounting mechanism; the electronic contract layer module provides distributed application services, uses blockchain technology for endorsement, and at the electronic contract layer, runs the code of sensitive data transactions of the system and the code of digital generation algorithm; SaaS The layer module provides cloud platform services, allowing all participants to participate in business collaboration conveniently through the web platform and client. This invention proposes a blockchain-based data transaction system for multiple parties to participate in the joint production of sensitive data. The final sensitive data is obtained by the final data generator, and other roles do not know the final data during the process of participating in the data production. Therefore Prevent sensitive data from leaking during circulation.

Description

technical field [0001] The present invention relates to the fields of blockchain technology and e-commerce technology, and in particular, to a system and method for sensitive data transaction based on blockchain. Background technique [0002] Anti-counterfeiting traceability has always been one of the necessary production factors for traditional enterprises. All products produced by regular enterprises have a two-dimensional code or one-dimensional code anti-counterfeiting label for anti-counterfeiting traceability query. The content of the label is essentially a string of numbers. Code (abbreviation: 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 takes the digital to make paper or plastic anti-counterfeiting labels, and then takes it to the industry customers (manufacturing enterprises). The industry customers label the production process and use the syst...
